Background: This review aimed to investigate the surgical, functional, and oncological outcomes of transoral laser microsurgery supraglottic laryngectomy (TOLM-SGL) for cT1-T3 laryngeal cancers., Methods: PubMed, Scopus, and Cochrane Library were searched by two independent investigators for studies investigating the surgical, functional, and oncological outcomes of TOLM-SGL using the PRISMA statements. A bias analysis was carried out with MINORS., Results: Twenty-four studies were included (937 patients), including 206 (25.9 %) cT1, 467 (58.7 %) cT2, and 123 (15.4 %) cT3 cases. Most patients were cN0 (63.9 %). The mean hospital stay of TOLM was 10.1 days. Aspiration (5.5 %), and bleeding (5.3 %) were the most prevalent complications. The laryngeal preservation rate was 93.7 %. Temporary tracheotomy was performed in 18.0 % of patients, with a mean time of decannulation of 6.8 days. A feeding tube was placed in 59.9 % of patients. The oral diet restarted after 6.4 days. Definitive gastrostomy was necessary in 2.4 % of cases. The 5-year OS and DFS were 70.1 % and 82.0 %, respectively. Distant metastasis, local, and regional recurrence occurred in 4.6 %, 11.6 %, and 5.1 % of patients. There was an important heterogeneity between studies for inclusion criteria, patient profiles, TOLM indications, and details of surgical, functional, and oncological outcomes., Conclusion: TOLM supraglottic laryngectomy is a safe, and effective procedure associated with adequate functional, surgical, and oncological outcomes. Future studies are needed to define the place of TOLM in advanced LSCC; the role and timing of concomitant bilateral neck dissection, the indications of tracheotomy and feeding tube., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: Primary fit tracheoesophageal puncture (TEP) is widely preferred for individuals who have not undergone prior radiation. However, there is no consensus on the relative utility of primary-fit TEP in the setting of salvage laryngectomy., Methods: A retrospective, single-center review was conducted of individuals undergoing laryngectomy with primary fit TEP between 2012 and 2018. Multivariable analysis was conducted to compare short-term and long-term complications, as well as speech and swallowing outcomes, of those who underwent primary versus salvage laryngectomy., Results: In this study, 134 patients underwent total laryngectomy with primary fit TEP. Aside from a higher rate of peristomal dehiscence (13.1% vs. 1.4%) found in the salvage group, there was no difference in incidence of all other complications, including pharyngocutaneous fistula formation. The groups had comparable speech and swallow outcomes., Conclusion: Primary fit TEP is a safe and effective surgical choice for individuals undergoing salvage laryngectomy who desire a voice prosthesis., (© 2024 The Authors.

Objectives: The aim of this study was to document 10-year outcomes after supracricoid partial laryngectomy (SCPL) in selected cT3M0 laryngeal squamous cell carcinoma (SCC) patients., Methods: This real-life retrospective observational study analyzed an inception cohort of 168 patients with isolated, untreated, selected cT3M0 laryngeal SCC, that were consecutively managed by SCPL during the period 1973-2013, and followed up until death or for a minimum of 10 years in 92% of cases at a single French academic and tertiary referral care center. Prior induction chemotherapy, arytenoid cartilage removal, level II-IV neck dissection, and postoperative radiation therapy were performed on 148, 77, 136, and 27 patients, respectively. The main objective was to determine 10-year actuarial local control and laryngeal preservation estimates. Secondary objectives included 10-year actuarial survival and cause-of-death analysis, and assessment of correlations between endpoints and clinical variables. The significance threshold was set at p < 0.005., Results: Ten-year actuarial local control, laryngeal preservation, and survival estimates were 90%, 85%, and 52%, respectively. Salvage treatment resulted in an overall 99% local control rate. Metachronous second primary cancer, intercurrent disease without evidence of SCC, SCPL-related death, and uncontrolled local recurrence accounted for 31%, 26%, 7%, and 2% of causes of death. On univariate analysis, overall local recurrence and laryngeal preservation rates varied significantly, from 5% to 54% and 90% to 46% when resection margins were R0 and R1, respectively., Conclusion: The present study highlighted successful 10-year outcomes after SCPL, providing further evidence in favor of its integration into the conservative armamentarium for endolaryngeal cT3 SCC., Level of Evidence: 4 Laryngoscope, 134:4557-4563, 2024., (© 2024 The Author(s).

Recurrent respiratory papillomatosis is medical condition strictly connected with HPV infection of the epithelium of the upper respiratory track. The main treatment of lesions located in larynx or lower pharynx includes microsurgical excision by using CO2 laser. A thorough preoperative assessment of patients is extremely important, which should not only be based on traditional laryngological examination, but also on endoscopy of the larynx and the use of the NBI (narrow band imaging) technique to assess the vascularization of lesions. In patients with recurrent papillomas, neoadjuvant therapy with antiviral agents or agents that inhibit angiogenesis is also often used. Among our group of 31 patients with laryngeal papillomas, 15 people (48%) required repeated surgical intervention and additional antiviral therapy while 10 (33%) people had to undergo the procedure three or more times due to disease recurrence. In this article we will discuss that laryngeal microsurgery with a CO2 laser is an effective method of treating patients with laryngeal papillomatosis and we will present the possibilities of adjuvant therapy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objective: To analyze oncological efficacy and voice outcomes of the 445-nm blue laser (BL) in the treatment of early glottic carcinoma and compare results with the 532-nm potassium-titanyl-phosphate (KTP) laser., Study Design: Single institution, retrospective chart review., Methods: All patients who underwent microlaryngoscopic KTP or BL laser excision of early glottic carcinoma from 2018 to the present day with at least 1-year follow-up were included. Primary and recurrent disease, including radiation and surgical failures, were included. Demographic data, voice outcomes and oncologic outcomes were compared between the two laser groups., Results: Forty-nine patients met the inclusion criteria for the BL group and 88 for the KTP group, with average follow-up of 635 and 1236 days, respectively. Oncologic outcomes were not significantly different, with disease-specific survival rates of 95.9% for BL and 100% for KTP (p = 0.13), organ preservation rates of 98.0% for BL and 95.6% for KTP (p = 0.39), and local control rates of 93.9% for BL and 92.1% for KTP (p = 0.81). Both BL and KTP groups showed significant improvement in CAPE-V (p = 0.04, 0.006 respectively) and VHI-10 scores (p = 0.003, <0.00001) following surgery., Conclusions: Photoangiolytic removal of early glottic carcinoma with BL appears to be equally safe and effective as with KTP laser at minimum one-year follow-up, and with excellent voice outcomes. Additional study will be warranted over time to assess long-term outcomes in BL patients., Level of Evidence: 3 Laryngoscope, 134:4656-4660, 2024., (© 2024 The Author(s).

Objective: This study aims to investigate how the impact of preoperative sarcopenia and inflammatory markers for laryngeal cancer patients and develop a new scoring system to predict their prognosis., Materials and Methods: Patients who underwent laryngectomy for laryngeal cancer (LC) from December 2015 to December 2020 at the Second Affiliated Hospital of Fujian Medical University were included. Independent prognostic factors were determined using univariate and multivariate analyses. A new scoring system (SFAR) was established based on FAR and preoperative sarcopenia, and statistically analyzed., Results: 198 cases included in this study that met the admission criteria. Multivariate analysis shown that preoperative sarcopenia, pTNM stage, and FAR were independent prognostic factors for laryngeal cancer. Based on these three indicators, we developed the SFAR scoring system. Multivariate analysis showed that SFAR was an independent predictor of laryngeal cancer (p < 0.001). SFAR was then incorporated into a prognostic model that included T-stage and N-stage, and a column-line graph was generated to accurately predict its survival., Conclusion: Systemic inflammation and sarcopenia are significantly associated with postoperative prognosis in laryngeal cancer. A new scoring system (SFAR) had implications for improving the prognosis of patients undergoing surgery for laryngeal cancer., (© 2024. The Author(s).)

Objective: To analyze long-term prognosis and influencing factors of recurrence in vocal fold leukoplakia treated by endoscopic cordectomy with CO 2 laser. Methods: A retrospective review was conducted on 599 patients with vocal fold leukoplakia [566 males and 33 females, aged 17-84 years (median age 55 years)], undergoing endoscopic cordectomy by CO 2 laser under general anesthesia at the Department of Otorhinolaryngology Head and Neck Surgery of Beijing Tongren Hospital, Capital Medical University, from January 2000 to December 2023. The study analyzed the clinical features, pathological grade, surgical methods, postoperative voice function, recurrence, malignant changes and analyzed the long-term efficacy and and its influencing factors. The patients were followed up for a duration of 6-249 months postoperatively, with a median follow-up time of 48 months. SPSS 20.0 software was used for statistical analysis. Results: Among the 599 patients, the histopathological grades included simple squamous cell hyperplasia in ( n =264, 44.08%), mild dysplasia ( n =96, 16.03%), moderate dysplasia ( n =74, 12.35%), severe dysplasia( n =43, 7.81%), carcinoma in situ( n =35, 5.84%), and carcinoma in situ with microinvasion( n =87, 14.52%). The 3-year and 5-year overall recurrence rates were 12.91% and 16.00%, respectively. In patients with precancerous lesion, 3.91% of recurrences presented with an upgraded pathologic grade and 2.34% evolved into carcinoma. The risk of recurrence was higher in lesions involving the anterior commissure, larger lesions, significant reduction/absence of mucosal waves, neovascularization/suspected neovascularization, and pathology of dysplasia/carcinoma in situ/carcinoma in situ with microinvasion( F =44.76,21.54,11.55,8.78,23.20,respectively, P< 0.05). Additionally, patients with recurrent disease exhibited higher reflux symptom index scores compared to those without recurrence. Exophytic lesion characteristics and the inability to cease smoking postoperatively were identified as independent risk factors for recurrence with an upgraded pathological grade, with odds ratios of 8.675 and 11.380 times greater than those with non-exophytic lesions and successful smoking cessation, respectively. At the 6-months postoperative assessment, patients who underwent subepithelial cordectomy (typeⅠ) demonstrated a statistically significant increase in fundamental frequency ( t =-3.38, P <0.05), and while other voice acoustic parameters were not significantly different.Conversely, those who underwent transmuscular cordectomy (TypeⅢ) exhibited significant alterations in multiple voice acoustic parameters when compared to preoperative values ( P <0.05). Furthermore, postoperative vocal fold adhesions developed in 84 patients with 13 of these individuals requiring surgical intervention for adhesion release. Conclusions: Lesions involving the anterior commissure, larger lesions, pathology of dysplasia/carcinoma in situ/carcinoma in situ with microinfiltration, significant reduction/absence of vocal fold mucosal waves, and neovascularization visible under NBI are indicative of an increased risk of recurrence, whereas exophytic lesions and the inability to cease smoking postoperatively significantly increase the risk of recurrence with elevated pathologic grade. Recovery of postoperative voice quality is procedure-dependent, underscoring the importance of surgical approach selection in the management of vocal fold leukoplakia.

Objective: To investigate the prognosis and influencing factors of endoscopic surgery for early glottic carcinoma. Methods: In this retrospective study, we applied the Cox proportional hazards regression model and the random survival forest model to analyze the clinical characteristics of 385 patients [362 males, 23 females, age ranging from 33 to 91 years (62.0±9.6)] who visited the Sixth Medical Center of the General Hospital of the People's Liberation Army from January 2009, to December 2022 and diagnosed with early glottic carcinoma, encompassing variables such as age, gender, T stage, surgical approach, pathological typing, etc. The primary evaluation indicators were overall survival(OS) and disease-free survival rates (DFS). The follow-up duration ranged from 30 to 5,557 days (with a median follow-up time of 1,596 days). Results: After a three-year follow-up, the OS rate for the 385 patients was 95.83%, while the DSF rate was 82.98%. The Cox proportional hazards regression analysis revealed age ( HR =2.35, 95% CI : 1.75 to 3.15, P <0.001) and T staging ( HR =1.59, 95% CI : 1.13 to 2.23, P= 0.019) as predominant factors affecting the OS and DFS. The random survival forest model identified poor tumor differentiation, and high expression of P53 and Ki-67 as predictors of inferior prognosis. Conclusion: Endoscopic surgery for early glottic carcinoma yields favorable short-term OS and reduces short-term recurrence rates, with T-stage emerging as a pivotal factor influencing recurrence. Tumors with poor differentiation and elevated expression of P53 may be indicative of an increased risk of recurrence.

Objective: To retrospectively analyze the clinical effect of biomaterial combined with silicone keel technology in the prevention and treatment of vocal folds adhesion. Methods: The basic data, perioperative conditions and prognosis of 21 cases of vocal folds adhesion treated by biofilm-silicone keel complex were retrospectively analyzed in Huashan Hospital Fudan University. Results: A total of 21 patients were enrolled in this study（19 males（90.5%）, 2 females（9.5%）. Among these patients, 18 cases of early glottic laryngeal carcinoma（T1b）, 1 case of bilateral vocal folds leukoplecta and 2 cases of postoperative vocal folds adhesion. No accidental rupture of the silicone keel occurred during perioperative period, and the silicone keel was removed in 22.4±2.6 days. All patients were reviewed after removing the silicone keel, the overall effective rate was 90.5%（19/21）. Postoperative complications occurred in 5 patients（1 laryngeal infection, 4 granulation tissue hyperplasia）, all of whom were cured after conservative treatment. Conclusion: This study explored the feasibility of biomaterial in the treatment of vocal folds adhesion. The biomaterial-silicone keel complex technology is simple to operate and has effect on the prevention of vocal folds adhesions, which is worth of clinical promotion., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Objective: Comparing the primary tumor control, vocal function recovery, postoperative adhesion rate and degree of adhesion in early glottic cancer involving the anterior commissure treated with CO₂ laser staged and lateral surgery, one-stage surgery combined with laryngeal stent placement, and simple CO₂ laser excision. Methods: This study focuses on 83 patients with T1-2N0M0 stage glottic squamous cell carcinoma involving the anterior commissure who underwent CO₂ laser treatment. The study was divided into three groups: Group A with 15 cases, treated with staged resection surgery; Group B with 18 cases, treated with one-stage surgery combined with the placement of a silicone laryngeal stent; and Group C with 50 cases, treated with simple CO₂ laser excision. The Voice Handicap Index-10（VHI-10）, the GRBAS auditory-perceptual assessment, and the maximum phonation time（MPT） were used to evaluate the vocal function of the patients before and six months after surgery. The degree of vocal cord adhesion was assessed using the Cohen classification of vocal cord adhesion. Statistical analysis was performed to determine the differences in each indicator before and after surgery, and the primary tumor control rates among the three groups. Results: Local recurrence occurred in 1 case each in Groups A and B, and in 4 cases in Group C, with no distant metastasis observed. Postoperative vocal cord adhesion of varying degrees occurred in a total of 77 cases, with an adhesion rate of 73.3%（11/15） in Group A, 88.9%（16/18） in Group B, and 100%（50/50） in Group C. The postoperative vocal cord adhesion rate and degree in Group C were significantly higher than in Groups A and B. The postoperative VHI-10 scores in all three groups were significantly increased compared to preoperative scores（ P <0.05）, and when compared between groups postoperatively, Group C was significantly worse than Groups A and B （ P <0.05）. The postoperative maximum phonation time（MPT） in Group C was significantly reduced compared to preoperative and was markedly shorter than that of Groups A and B postoperatively（ P <0.05）. The postoperative grades of G（Grade） and R（roughness） in Group C were significantly higher than preoperatively, indicating a noticeable deterioration in voice quality, and were also significantly worse than those postoperatively in Groups A and B, with all differences（ P <0.05）. Conclusion: For early glottic cancer involving the anterior commissure, choosing staged surgery or one-stage surgery combined with the placement of a silicone anterior commissure laryngeal stent were better than simple laser tumor excision in terms of secondary vocal cord adhesion and voice function preservation., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Background: The study evaluated the prognostic impact of the immune microenvironment in LSCC with markers of major immune cells to identify the key determinants of short-term disease-free survival (ST DFS) and reveal factors related to disease progression., Methods: The study cohort included 61 patients who underwent total laryngectomy, 83.6% of whom were male with a mean age of 64.3 years at the time of surgery. Twenty-five patients had long term DFS (over 5 years), 8 - had moderate DFS (between 2 and 5 years), and 28 had short-term DFS (less than 2 years). Immunohistochemical staining and evaluation were performed on samples collected after the laryngectomy., Results: The samples' assessment revealed that the mean expression of all analysed markers was the highest both in stroma and the tumor compartment for short term DFS (ST DFS) patients. Analysis confirmed that a high stromal density of CD8 cells (p = 0.038) significantly correlated with DFS, and that the increased presence of CD57 cells (p = 0.021) was significantly associated with ST DFS. Moreover, the high density of CD68 cells in the tumor epithelial compartment had a negative prognostic impact on DFS (p = 0.032). Analysis of overall survival in the studied cohort with Kaplan-Meyer curves revealed that a high stromal density of CD68 cells was a significant negative predictor of OS (p = 0.008)., Conclusions: The observed associations of CD68 cells infiltration with progression and prognosis in patients with LSCC provide potential screening and therapeutic opportunities for patients with unfavourable outcomes., (© 2024.

Over the last 2 decades, the paradigm of laryngeal cancer management has pivoted toward preserving laryngeal function without sacrificing oncologic outcomes. Transoral laser microsurgery has diminished the role of open laryngeal surgery. For early-stage laryngeal cancer, the common primary modalities are endoscopic laryngeal surgery and narrow field radiation. Total laryngectomy followed by either radiation or chemoradiation is option for advanced laryngeal cancer. In experienced hands and following meticulous patient selection, supracricoid laryngectomy may serve as a viable alternative to total laryngectomy to preserve laryngeal function. Total laryngectomy is still the recommended treatment in those with airway compromise and/or laryngeal dysfunction., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2024 Elsevier Inc.

Purpose: The study aimed to identify parameters that could predict oncological and functional outcomes in patients with pT4aN0 laryngeal squamous cell carcinoma (LSCC) who underwent open partial horizontal laryngectomy (OPHL). The role of paratracheal neck dissection (PTND) was analyzed as the primary outcome. Additionally, the study compared the outcomes of patients who underwent postoperative radio/chemotherapy (PORT/PORCT) with those who refused or did not adhere to adjuvant treatments., Methods: Twenty-nine OPHL patients whose pathological exam was consistent with pT4aN0-x disease were enrolled and their clinical charts were retrospectively reviewed. The study analyzed oncological outcomes, such as local, regional, and distant recurrence rates (RR), overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS). Additionally, functional results were analyzed, including decannulation rate, hospitalization time, and postoperative complication rate., Results: The study revealed and overall recurrence rate of 27%. The final rates for OS and DSS were 68% and 79%, respectively. Based on the univariate analysis the PTND was significantly associated with longer DFS. No significant differences inoncological outcomes were observed between pT4a patients who underwent adjuvant radio/radiochemotherapy and those who did not, in terms of RR, DFS, DSS or OS. However, adjuvant treatment was found to significantly increase decannulation time., Conclusions: In a properly super-selected subgroup of patients with pT4aN0 LSCC, OPHL may beconsidered as a conservative surgical option even without adjuvant treatment. However, for optimal oncological outcomes, it is strongly recommended to consider a central compartment dissection in cases of hypoglottic and anterior extra-laryngeal tumor extension., (© 2024.

Open Partial Horizontal Laryngectomy (OPHL) Type IIa surgery is a conservative surgical technique used in the treatment of laryngeal carcinomas. In this pilot study, we aimed to characterize swallowing function and physiology in a series of patients after OPHL Type IIa surgery through comparison to healthy reference values for quantitative measures for videofluoroscopy. We performed retrospective quantitative analysis of videofluoroscopy recordings of thin liquid swallows for a preliminary sample of 10 male patients. Each videofluoroscopy clip was rated in triplicate by trained blinded raters according to the ASPEKT Method (Analysis of Swallowing Physiology: Events, Kinematics and Timing). This preliminary sample of patients with previous OPHL surgery showed functional airway protection, with only 2 patients showing incomplete laryngeal vestibule closure (LVC) and associated airway invasion. However, the majority of patients (90%) showed prolonged latencies to LVC and upper esophageal sphincter (UES) opening. Prolonged durations of LVC and UES opening were also noted, but these were in the direction of compensation rather than impairment. Reduced pharyngeal area at rest was seen in 70% of the sample, and all patients showed poor pharyngeal constriction. Post-swallow residue was a prominent finding in ≥ 75% of these patients. In particular, reduced or absent constriction of the hypopharynx in the region of the pyriform sinuses was noted as a characteristic of swallowing in this sample. The data from these patients suggest that despite functional airway protection, severe swallowing dysfunction involving poor pharyngeal constriction and bolus clearance may be likely after OPHL surgery., (© 2024.

Rhabdomyomas are rare benign mesenchymal tumors of the skeletal muscles and uncommon in the head and neck region. Laryngeal rhabdomyomas are much rarer. We present the case of a 32-year-old woman who was admitted to our hospital for shortness of breath due to pneumothorax. As otolaryngologists, we were consulted for a soft tissue tumor over the left side of the larynx that was accidentally found on the chest computed tomography (CT). The patient underwent laryngomicrosurgery for tumor biopsy, and histological examination revealed a laryngeal rhabdomyoma. After the operation, magnetic resonance imaging of the neck was performed and the tumor was suspected as rhabdomyosarcoma. Positron emission tomography/computed tomography (PET/CT) showed an 18F-fluoro-2-deoxy-D-glucose (FDG)-avid soft tissue mass on the left side of the larynx. After complete tumor removal via transoral laser microsurgery, no recurrence was reported for 5 years., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Spindle cell lipoma is a very rare occurrence in the larynx and can be cured by complete excision. In this case report we present the case of a 71-year-old female who presented to the otorhinolaryngology outpatient department of Northwest General Hospital and Research Centre, Peshawar, with complaints of occasional irritation and a foreign body sensation in the throat while swallowing, for the last three years. She had undergone a surgical procedure 30 years back for the same complaint and remained asymptomatic till three years back. On examination, through fibre-optic laryngoscope, the attending surgeon saw an abnormal mass arising from the aryepiglottic folds of the larynx. An excisional biopsy was performed through micro-laryngoscopy. The patient's symptoms subsequently improved and she is currently doing well. Histopathological reports confirmed it as spindle cell lipoma.

Background: The purpose of this multicenter study was to retrospectively investigate the prognostic significance of the tumor microenvironment, in relation to survival in a large cohort of patients with laryngeal squamous cell carcinoma (LSCC), using the method proposed by the International TILs Working Group in breast cancer., Methods: All consecutive patients with biopsy-proven LSCC who underwent total laryngectomy (TL) between January 2014 and January 2023 were retrospectively included in the study. A retrospective review of medical records including surgical, pathological and follow-up reports was performed. The density of TILs was determined according to the recommendations of the International TILs Working Group., Results: The study group included 186 patients with LSCC. High TILs were statistically correlated with reduced size and extension of primary tumor (pT stage) with a statistically significant value (S: p = 0.01; P: p = 0.0003) and without needs of salvage therapy (S: p = 0.03; P: p = 0.004). Low TILs were indicative of worse prognosis., Conclusions: Our study confirmed the protective value of TILs and the prognostic role of the tumor microenvironment in LSCC; furthermore, our results showed that the score proposed by the International TILs Working Group for breast cancer can be applied to LSCC., (© 2024 Wiley Periodicals LLC.)

Purpose: In laryngeal squamous cell carcinoma (LSCC) treated with transoral laser microsurgery (TOLMS), the status of margins significantly affected local control. When a positive or close margin is present, there is no ubiquitous consensus regarding further treatments. The rationale of the present systematic review and meta-analysis is to investigate the survival impact of the status of the margins in patients affected by LSCC treated with TOLMS., Data Sources: PubMed, EMBASE, and Cochrane Library., Methods: We performed a systematic search, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were: patients affected by LSCC, staged according to the American Joint Committee on Cancer Staging System and treated by TOLMS without any previous treatment; margins status (close, positive, negative) and the adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) of overall survival, disease-specific survival, and disease-free survival has to be reported., Results: Nine studies were deemed eligible for the qualitative analysis, and 3 for the quantitative analysis to investigate the association between margin status and OS. The cumulative number of patients was 3130. The sample size ranged from 96 to 747 patients. The follow-up period ranged from 0 to 201 months. The meta-analysis results show that positive margins have an aHR of 1.30 yet with CI range (0.56 to 2.97)., Conclusions: Our current meta-analysis results are unable to definitively assess the real impact of resection margins on OS. Few authors provide accurate data regarding position and types of margins. Further prospective or high-quality studies are required., (© 2024.

Objective: The larynx is the second most prevalent subsite for head and neck cancer. Over half of head and neck cancer patients present with advanced disease. We report our regional practices for palliative intent laryngeal squamous cell cancer (SCC)., Methods: Retrospective analysis of patients with laryngeal SCC treated with palliative intent, discussed at the regional head and neck multidisciplinary team meeting from July 2010 to June 2016., Results: A total of 65 patients were included, of whom 45 per cent had potentially curable disease but were not fit for curative treatment. Nine patients (14 per cent) underwent tracheostomy, with mean survival and hospital stay of 278 and 48 days, respectively. Four patients (6 per cent) underwent debulking surgery with mean survival and hospital stay of 214 and 1 days, respectively., Conclusion: All palliative treatment measures offered to patients can have an impact on survival and quality of life. Patients should be at the centre of the decision-making process and counselled on the potential impact of interventions.

Background: With advancements in medicine and economy, it would be expected that there will be changes in the clinical characteristics of upper respiratory papillomatosis. The aim of this study was to examine the current clinical characteristics of upper respiratory papillomatosis, as there are no recent data in the literature., Methods: The medical records of 1894 patients with upper respiratory papillomatosis were retrospectively reviewed. Data extracted included clinical features, laryngoscopy images, and surgical procedure data., Results: The upper frequency of upper respiratory papillomatosis in the oropharynx was 69.1 %, and in the larynx was held 28.9 %. The overall postoperative relapse rate was 2.4 %. The relapse rate of laryngeal papillomatosis was 6.5 %. Approximately 2.6 % of cases were in children. All postoperative recurrences in children were laryngeal, and the recurrence rate was 30.4 %., Conclusion: The oropharynx has the highest frequency of upper respiratory papillomatosis. The larynx, however, has the highest rate of postoperative recurrence. Compared to adults, children are more likely to experience a postoperative recurrence., Competing Interests: Declaration of competing interest The authors have declared that no competing interest exists., (Copyright © 2024 Elsevier Inc.

Objective: Transoral robotic surgery total laryngectomy is a promising procedure. We conducted a systematic review to study the indications, surgical techniques and complications of this procedure., Methods: We followed the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement., Results: We concluded with 5 studies and 27 surgeries. The main indications of transoral robotic surgery total laryngectomy were selected recurrent laryngeal squamous cell carcinomas, dysfunctional larynx, and specific primary non-squamous cell carcinoma laryngeal cancers. The rate of pharyngocutaneous fistula was 20 per cent overall. In every reported cancer case, the specimen was excised within negative surgical margins. The average time of the procedure was 282.6 minutes., Conclusion: Transoral robotic surgery total laryngectomy is a safe procedure of high value. The preservation of strap muscles and hyoid bone as well as the sacrifice of less mucosa compared to the traditional technique reduces the risk of certain complications and improves the swallowing outcome.

Laryngeal transplant (LT) is a promising option to restore quality of life in patients with severe laryngeal dysfunction or a laryngectomy. These patients may be tracheostomy tube dependent or gastrostomy tube dependent and may lose their ability to verbally communicate. The loss of these important functions frequently results in social isolation and a severe decrease in quality of life. Laryngeal transplant has the potential to restore all of these important laryngeal functions.

Objective: This study aimed to solve the debate over the role and extent of neck dissection to treat any occult nodal metastasis in patients undergoing salvage laryngectomy for recurrent and/or residual squamous cell carcinoma of larynx., Methods: This was a retrospective study over a time frame of 6 years (2016-2022) of 74 patients who underwent bilateral neck dissection and salvage laryngectomy for recurrent or persistent disease with N0 neck. We calculated the incidence of occult nodal metastasis in ipsilateral and contralateral neck., Results: Incidence of ipsilateral neck disease was calculated as 8.11 per cent and it was 0 per cent in contralateral neck. Regarding ipsilateral nodal level distribution, level II was the highest at 6.76 per cent, followed by level III at 5.41 per cent. There was 0 per cent metastasis in levels IV and IIb., Conclusion: In patients undergoing salvage laryngectomy with N0 neck, ipsilateral super selective neck dissection is considered a convenient and oncologically safe option to treat the neck.

Background: Voice outcome after carbon dioxide transoral laser microsurgery (CO 2 TOLMS) for glottic cancer is of prime importance. However, a comprehensive overview according to the European Laryngological Society (ELS) classification of cordectomies is still lacking. The aim of this systematic review is to summarize data on voice outcome associated with individual types of ELS glottic cordectomy after CO 2 TOLMS., Materials and Methods: A systematic review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The initial search identified 936 records of which 25 publications were then included. Voice outcome data (Voice Handicap Index [VHI] version 30, grade of dysphonia [G] and maximum phonation time [MPT]) were extracted per resection type. Weighted averages were calculated., Results: Data show a gradual increase in the VHI scores although they were still similar for all cordectomy types (range 14.2 to 21.5). The grade of dysphonia showed a gradual increase with increasing resection depth (range 1.0 to 1.9). There was a gradual decrease in the MPT (range 15.2 to 7.2)., Conclusion: Voice outcome is related to cordectomy type with mild dysphonia characterizing ELS type I, II and III cordectomies, while more extended cordectomies (ELS type IV, V and VI) result in moderate dysphonia and shortness of breath during phonation. The voice handicap experienced by patients is limited even in the more extended cordectomies., (Copyright © 2022. Published by Elsevier Inc.)

Objective: Open partial horizontal laryngectomies (OPHLs) represent a comparable alternative to total laryngectomy and nonsurgical protocols in selected cases. While short-term functional outcomes of OPHLs have been widely investigated, few have focused on the effect of aging on residual laryngeal structures., Study Design: Retrospective cohort study., Setting: Tertiary care academic center., Methods: Patients who underwent OPHLs after at least 1 year follow-up and optimal functional rehabilitation were included in the study. Swallowing function was assessed according to PAS (Penetration aspiration scale) and Pooling scores. Spectrogram analysis of voice was conducted according to Yanagihara classification and acoustic parameters were also recorded. Subjective questionnaire data about phonation and swallowing were also recorded. Data obtained were compared among patients according to age at time of surgery, evaluation and duration of follow-up., Results: Ninety-seven patients were enrolled with a mean age at surgery and evaluation of 63 and 70 years old, respectively. Median follow-up length was 5 years. OPHL type II was mostly performed. No significant correlation was observed between most of the analyzed variables and patient's age at the time of surgery and at the time of evaluation. Some acoustic parameters were negatively correlated with follow-up length, while Jitter, NHR (Noise-Harmonic Ratio), and Global grade and Roughness were significantly higher in patients >65 years old., Conclusion: Patients who complete rehabilitation reach equally good results as their younger peers with stability over time. Finally, the effects of aging on residual larynx are of minor entity compared to the nonoperated patients., Level of Evidence: Level IV-retrospective cohort study., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objectives: The aim of this study is to compare voice outcomes in open partial horizontal laryngectomy vs. total laryngectomy (TL) with voice prosthesis., Methods: In this retrospective monocentric study patients undergoing OPHL or TL with voice prosthesis were enrolled during the usual oncological follow-up consultations at the Otolaryngology and Audiology Unit of a University Hospital in the period between July 2022 and June 2023. Acoustic analysis (F0, HNR, NHR), maximum phonation time, I-SECEL and INFV0 scale were used to assess voice outcome., Results: Forty-three patients were enrolled. Voices of patients undergoing LT were better in quality of voice (V0) at INFV0 scale. The scores in I-SECEL and acoustic analysis were comparable., Conclusions: Voice quality could be slight better in patients undergoing TL with voice prosthesis than those undergoing OPHL., (© 2024.

Objective: Advanced-stage laryngeal squamous cell carcinoma is treated with primary surgery or chemoradiation. We aim to determine if there are differences in postoperative functional oral intake in primary (PL) versus salvage laryngectomees (SL)., Study Design: Retrospective cohort study., Setting: Patients who underwent laryngectomy between 2011 and 2021., Methods: We examined demographic, diagnostic, treatment, and swallow function data pre- and postoperatively. A follow-up survey was distributed to assess current swallow status., Results: One hundred twenty-five patients were included. Preoperatively, 68.8% of patients reported dysphagia. Median functional oral intake score (FOIS) was 4.0 [interquartile range, IQR: 1.0-6.75]. The SL group had lower preop FOIS [2.0; IQR: 1.0-4.75] that did not reach significance compared to the PL group [4.5; IQR: 1.0-7.0] (P = .052). 73.4% of patients had a feeding tube. The PL group was more likely to have the tube removed [odds ratio, OR: 2.4; confidence interval, CI: 1.0-5.7]. The SL group was more likely to require feeding tube placement more than 6 months postop [OR: 6.9; CI: 1.65-32.6]. SL FOIS scores improved by 3 months postop to 5 (SL ΔFOIS = 3, P = .0150). PL scores improved to 7 [PL ΔFOIS = 2, P = .0005] at 12 to 15 months. Sixty-nine patients were contacted for a follow-up survey and 16 completed this survey. 30.4% patients reported dietary restrictions (mean 4.4 years postop)., Conclusion: Patients undergoing SL appear to obtain similar swallow outcomes compared to PL at 3 to 6 months postlaryngectomy, but plateau. The PL group continues to improve up to 1 year postoperatively. Fifty percent of patients report on-going dysphagia after 5 years., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objective: Laryngeal cancer is a common tumor in the head and neck, and surgery is one of the main treatment methods for laryngeal cancer. Laryngeal cancer surgery destroys the laryngeal cartilage scaffold, leading to structural changes in the laryngeal cavity and affecting respiratory compliance during sleep. However, less attention has been paid to the impact of changes in laryngeal structure on sleep breathing conditions. This article conducts a prospective study on the effects of preserving laryngeal function in cancer glottic surgery on sleep and respiratory status in patients, in order to understand the preoperative and postoperative OSAHS(obstructive sleep apnea-hypopnea syndrome) of glottic cancer patients , as well as the impact of surgery on OSAHS of patients. Provide a reference for improving the sleep quality of postoperative patients with laryngeal cancer., Methods: 47 patients with glottic cancer who underwent laryngeal function preservation surgeries were studied. They are divided into 28 cases of T1 and T2, who underwent vertical lateral frontal partial laryngectomy (VLFPL), and 19 cases of T3 and T4 who underwent vertical lateral frontal subtotal laryngectomy (VLFSL). All patients' sleep breathing statuses were recorded using a portable sleep breathing monitor one week before surgery and two months after the removal of the tracheal cannula. Analyze the proportion of OSAHS in the 47 patients before and after surgery and compare the obstructive sleep apnea scores of these patients using the Wilcoxon rank sum test of paired grade data. The paired data t-test was used to analyze the apnea-hypopnea index (AHI), apnea index (AI), hypopnea index (HI), minimum blood oxygen saturation (LSaO2), and mean blood oxygen saturation (MSaO2) of all study subjects, patients undergoing VLFPL and VLFSL., Results: 1. Among the 47 patients with glottic cancer, 42.6% (20 / 47) were in line with OSAHS before the operation, and 57.4% (27 / 47) were in line with OSAHS after the operation. 47 patients showed an increasing trend in the OSAHS scores (no, mild, moderate, and severe) after surgery compared to the before-surgery scores, and the difference was statistically significant (P < 0.05). 2. Among the 47 study subjects, AHI and HI increased after surgery compared to preoperative, while LSaO2 and MSaO2 decreased after surgery compared to preoperative (P < .05); There was no statistically significant difference between postoperative and preoperative AI (P > .05). Among 28 patients undergoing VLFPL, LSaO2 decreased after surgery compared to before surgery (P < .05) and there was no statistically significant difference in AHI, AI, MSaO2, and HI after surgery compared to before surgery (P > .05). Among 19 patients undergoing VLFSL, AHI, and HI increased after surgery, while LSaO2 and MSaO2 decreased after surgery (P < .05) and there was no statistically significant difference in postoperative AI compared to preoperative (P > .05)., Conclusion: The prevalence of OSAHS in patients with glottic cancer before and after surgery was higher than that in the general population. The effect of functional preservation surgery on sleep breathing in patients with glottic cancer is related to the degree of destruction of the thyroid cartilage scaffold and the scope of surgery. Surgery mainly increases the degree of OSAHS by aggravating patients' hypoventilation rather than apnea.

Objective: We evaluated vessel counts in the pharyngeal mucosal margins of patients who underwent salvage laryngectomy to establish whether mucosal vascularity might predict fistula risk., Study Design: Retrospective cohort., Setting: Tertiary Medical Center., Methods: Patients who underwent salvage total laryngectomy at our institution between 1999 and 2015 were identified. Pharyngeal mucosal margins from laryngectomy specimens were evaluated histologically for each patient, and vessel counts were performed on 5 ×10 images. The primary outcome measure was fistula within 30 days of surgery and mean vessel counts were assessed as the principle explanatory variable., Results: Seventy patients were included and 40% developed a postoperative fistula. There was a large difference in the mean vessel count in patients who did develop fistula (48.6 vessels/×10 field) compared to those who did not (34.7 vessels/×10 field). A receiver operative characteristic curve found that a cutoff value of 33.9 vessels/×10 field provided a sensitivity of 75% and specificity of 62% to predict the likelihood of fistula occurrence (area under the curve = 0.71, 95% confidence interval [CI]: 0.59-0.83). In a binary logistic regression, patients with vessel counts greater than 33.9 had a 5-fold increased risk of developing fistula (95% CI: 1.8-16.45). Histologically, vessels in the pharyngeal mucosa of patients who developed fistulas were more disorganized., Conclusion: After salvage laryngectomy, patients with higher mean mucosal margin vessel counts are at increased risk of fistula. The mechanism is unknown, but the disorganization of the vasculature may contribute to poor wound healing. Vessel counting may allow for fistula risk stratification and guide postoperative care., (© 2024 The Author(s).

Laryngeal schwannomas are rare benign neurogenic tumors of the larynx. They cannot be detected in the early stages because disease onset is asymptomatic. This case of laryngeal schwannoma provided a reference for clinical diagnosis and treatment strategy. A 24-year-old man presented with a 3-year history of hoarseness and sore throat for 6 months. Laryngoscopy and computed tomography showed submucosal bulging of the right ventricular fold in the right paraglottic space. The patient underwent tracheotomy first, followed by laryngotomy. The edema of the laryngeal mucosa was significantly alleviated, with normal movement of the bilateral vocal cords on the 10th day after surgery. The tracheal tube was removed at the time of discharge. The hoarseness had disappeared at the end of the first month after surgery. The effective treatment of laryngeal schwannoma involves complete resection with surgery while protecting the integrity of the larynx and restoring laryngeal function. The indication for surgery should be strictly controlled to avoid damage to the mucosa and structures of the larynx., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Frozen biopsy may guide surgical intraoperative decisions. We evaluated the accuracy of frozen biopsy for diagnosing benign, dysplastic and malignant laryngeal lesions, compared to paraffin section (gold standard)., Methods: Retrospective review of the charts of all patients presenting with laryngeal lesions suspicious of malignancy, who underwent laryngeal microsurgery with frozen biopsy in our institution, between 2015 and 2020. Results of frozen biopsy and paraffin section examinations were compared., Results: Among 113 samples of 89 patients, paraffin section diagnosed 23 benign, 31 dysplastic and 59 malignant lesions. The accuracy of the frozen biopsy in identifying dysplasia or malignancy was 80.5% (91/113), and greater for lesions >5 mm (78.8% × 51.5%; p = 0.009). The positive and negative predictive values, sensitivity and specificity were 95.9%, 51.3%, 78.9% and 86.9%, respectively., Conclusions: Frozen section is a reliable tool when malignancy is detected, but almost half of benign results exhibit dysplasia or malignancy in paraffin section. Other clinical parameters should be considered in intraoperative decisions to prevent undertreatment., (Copyright © 2024. Published by Elsevier España S.L.U.)

Objective: This study aimed to evaluate rate of the COVID-19 disease, its severity, mortality rate and anxiety levels in subjects who underwent total laryngectomy., Methods: The subjects who underwent total laryngectomy were included in the study. The data were first obtained retrospectively and then a telephone survey was applied. Anxiety levels was evaluated by the Coronavirus Anxiety Scale (CAS)., Results: A total of 54 subjects were included in the study. Nine (16.7%) males were reported to be infected with SARS-CoV-2. Five (55%) of them were hospitalized; 2 of them (22%) were taken to intensive care units, and one subject (11%) died. Although a tendency to increase risk of COVID-19 disease in the tracheoesophageal voice prosthesis users (23.1% vs 14.63%) was observed, statistically difference was not significant. The average total CAS score was significantly higher in those who had COVID-19., Conclusion: The data documented that people who underwent total laryngectomy developed more frequent and more severe COVID-19 disease and had a higher mortality rate. Although no obvious variable was found, our data suggest that using a tracheoesophageal voice prosthesis may be somewhat effective. Besides, our subjects presented very low anxiety about COVID-19.

Objective: To explore the differences between clinical features and computed tomography (CT) findings of early-stage glottic cancer (EGC) with or without recurrence after transoral laser microsurgery (TLM) and to establish a preoperative nomogram to predict postoperative recurrence., Methods: The clinical and CT features of 168 consecutive patients with EGC with or without recurrence were analyzed retrospectively. Multivariate logistic regression analysis was used to determine the independent predictors of recurrence. A nomogram was constructed to preoperatively predict recurrence. To assess the nomogram's performance, the C-index and calibration plot were used., Results: EGCs with and without recurrence differed significantly in T-stage, depth, and normalized CT values in the arterial phase (NCTAP) and venous phase (NCTVP) (all P < 0.05). T-stage, depth, and NCTVP were independent predictors of recurrence in EGCs (all P < 0.05). The C-index (0.765, 95% confidence interval: 0.703-0.827) and calibration plot showed that the nomogram has good prediction accuracy. Nomograms based on T-stage and CT variables provided numerically predicted recurrence rates and were better than those based on only T-stage (C-index of 0.765 vs. 0.608)., Conclusions: Using clinical and CT variables, we developed a novel nomogram to predict the recurrence of EGC before TLM, which may be a potential noninvasive tool for guiding personalized treatment., (Copyright © 2024 Copyright: © 2024 Journal of Cancer Research and Therapeutics.)

No previous study has published magnetic resonance imaging (MRI) findings for a subglottic pleomorphic adenoma. Here, we describe the case of a 62-year-old man with a subglottic pleomorphic adenoma. Endoscopic findings revealed a smooth-surfaced tumor arising from the subglottic posterior wall. MRI revealed the lesion as an isointense region on T1-weighted images, which was homogeneously enhanced. This lesion showed a heterogeneously hyperintense region on T2-weighted images. Diffusion-weighted imaging (DWI) showed slightly high intensity in the same area, with a normal or only slightly high apparent diffusion coefficient (ADC). Laryngomicrosurgery was performed for transoral excision of the subglottic tumor, resulting in a postsurgical diagnosis of pleomorphic adenoma., Competing Interests: No potential conflict of interest relevant to this article was reported.

Objectives: Decision-making for patients with a locally advanced laryngeal carcinoma (T3 and T4) is challenging due to the treatment choice between organ preservation and laryngectomy, both with different and high impact on function and quality of life (QoL). The complexity of these treatment decisions and their possible consequences might lead to decisional conflict (DC). This study aimed to explore the level of DC in locally advanced laryngeal carcinoma patients facing curative decision-making, and to identify possible associated factors., Methods: In this multicenter prospective cohort study, participants completed questionnaires on DC, level of shared decision-making (SDM), and a knowledge test directly after counseling and 6 months after treatment. Descriptive statistics and Spearman correlation tests were used to analyze the data., Results: Directly after counseling, almost all participants (44/45; 98%) experienced Clinically Significant DC score (CSDC >25, scale 0-100). On average, patients scored 47% (SD 20%) correct on the knowledge test. Questions related to radiotherapy were answered best (69%, SD 29%), whilst only 35% (SD 29%) of the questions related to laryngectomy were answered correctly. Patients' perceived level of SDM (scale 0-100) was 70 (mean, SD 16.2), and for physicians this was 70 (SD 1.7)., Conclusion: Most patients with advanced larynx cancer experience high levels of DC. Low knowledge levels regarding treatment aspects indicate a need for better patient counseling., Level of Evidence: 4 Laryngoscope, 134:3604-3610, 2024., (© 2024 The Authors.

Objective: Tracheoesophageal puncture (TEP) is one of the most established methods for voice reacquisition following total laryngectomy. The most difficult complication following TEP is the management of saliva leakage or secretion into the trachea due to TE fistula enlargement. In this study, we devised a new strategy to close TE fistulas and confirmed its safety and effectiveness., Methods: Skin incision: If the tracheal mucosa around the voice prosthesis appears intact and normal, an arcuate incision, from 10 to 2 o'clock, is made on the skin 5 mm superior to the edge of the stoma. However, if the surrounding tracheal mucosa is fragile because of leaking, the incision is made on the superior edge of the stoma, with later reconstruction of the posterior tracheal wall. Separation of the trachea and esophagus: If the esophagotracheal spatium appears normal and is easy to dissect, the connective pipes can be found easily. After cutting the pipe, a ligature alone is sufficient for the tracheal side; however, the esophageal wall is closed with Gambee sutures. If the esophagotracheal spatium is compromised and the posterior tracheal wall is fragile (due to saliva leakage), we remove the posterior wall and reconstruct the area using the superior skin flap. We performed our novel method on four patients with intractable conditions; postradiotherapy for laryngeal cancer, total pharyngo-laryngo-esophagectomy (TPLE) with jejunum reconstruction, TPLE with gastric lifting reconstruction, and in a patient who underwent cervicothoracic incisional drainage for descending necrotizing mediastinitis., Results: None of the cases showed postoperative leakage from the fistula, and oral intake was resumed without difficulty., Conclusion: This study showed that this strategy based on TE fistula conditions is effective even in difficult-to-treat cases., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

Purpose: Many series have compared voice quality after radiotherapy or surgery for cT1 glottic carcinoma. Different meta-analyses identify better results for radiotherapy while others do not identify any difference, some finally find a superiority of surgery. The purpose of this study was to compare the voice quality in the long term of patients who underwent transoral surgery versus exclusive irradiation for the treatment of cT1 glottic carcinoma., Material and Methods: The VOQUAL study was a pilot comparative multicenter cross-sectional study. The primary endpoint was the Voice Handicap Index comparison between two groups (radiotherapy or surgery). The voice assessment also consisted in the heteroevaluation of voice quality by the Grade, Roughness, Breathness, Asthenia, and Strain rating scale reported by Hirano., Results: The study included 41 adult patients with cT1 carcinoma of the vocal cord treated by cordectomy or exclusive radiation in two oncologic centers. The median Voice Handicap Index value was 20 [8; 32.5] in the surgery group and 10 [4; 18.5] in the radiotherapy group. There was no statistically significant difference between the median values and the various components F, P and E of the questionnaire (P=0.1585). The median value of the numeric dysphonia Grade, Roughness, Breathness, Asthenia, and Strain scale was 2 [0; 5] in the surgery group and 2 [0.25; 3.75] in the radiotherapy group. There was no statistically significant difference between these values (P=0.78)., Conclusion: Our study did not show any significant difference on the primary endpoints of Voice Handicap Index and Grade, Roughness, Breathness, Asthenia, and Strain scores., Level of Evidence: III., Clinical Trial Registration: The VOQUAL study was registered on the ClinicalTrials.gov platform under the number NCT04447456, in July 2020., (Copyright © 2024 Société française de radiothérapie oncologique (SFRO).

Purpose: Current literature lacks consensus on risk factors for pharyngocutaneous fistula (PCF), and empirical antibiotic guidelines for PCF are limited. The aim of this study was to reduce the incidence of PCF and improve antibiotic treatment efficacy for patients with PCF after open neck surgery by analyzing their clinical characteristics, pathogenic bacteria, and antibiotic susceptibility., Methods: This study was a 13-year single-center retrospective cohort study, including 699 patients who underwent open neck surgery for laryngeal and hypopharyngeal cancer. Univariate and multivariate logistic regression analyses were conducted to identify the risk factors associated with the occurrence of PCF after surgery. The microbial species causing PCF were analyzed, and the antibiotic sensitivity of the top three pathogens was assessed. Venn diagrams were used to illustrate the antibiotics that exhibited 100% sensitivity against all three identified pathogens., Results: The incidence of PCF after open neck surgery was 8%. Logistic univariate and multivariate analyses revealed that flap reconstruction (OR = 3.62, 95% CI [2.02-6.52]), history of preoperative radiotherapy (OR = 2.01, 95% CI [1.31-2.73]), significant postoperative bleeding (OR = 1.79, 95% CI [1.11-2.69]), and history of diabetes (OR = 1.34, 95% CI [1.29-2.46]) were significantly associated with PCF occurrence. Among the 38 cases of PCF patients, the top three identified pathogens were Pseudomonas aeruginosa, Escherichia coli, and Enterobacter cloacae. The antibiotics cefepime, meropenem, ticarcillin/clavulanic acid, and cefoperazone/sulbactam showed 100% sensitivity against these top three pathogens., Conclusion: Special attention should be given to patients undergoing open neck surgery, especially those with intraoperative flap reconstruction, a history of preoperative radiotherapy, postoperative bleeding, or diabetes. Strengthening monitoring and care is crucial in preventing the occurrence of PCF. According to antibiotic usage guidelines and considering the distribution of pathogens in PCF patients, empirical antibiotic treatment with cefoperazone/sulbactam or ticarcillin/clavulanic acid is recommended prior to obtaining susceptibility test results., (© 2024.

Background and Objectives: To analyze oncological and functional results of transoral minimally invasive surgery (TMIS) for supraglottic laryngeal carcinoma (SGLC), and investigate independent prognostic factors., Methods: Seventy SGLC patients treated with TMIS were included. The overall survival (OS), recurrence-free survival (RFS), and postoperative functions were analyzed., Results: Sixty-two patients were early-stage (Tis, T1, and T2) and eight patients were T3. Eleven patients received preoperative induction chemotherapy (IC). Sixty patients received transoral laser microsurgery (TLM), and 10 patients received transoral robotic surgery (TORS). Fifty-eight patients were scored Grade-1 by water swallow test, and 49 patients were scored Grade 0 by grade, roughness, breathiness, asthenia, strain. The 1, 3, and 5 year OS of all were 95.450%, 84.877%, and 78.026%, and RFS were 89.167%, 78.052%, and 75.451% respectively. Kaplan-Meier survival analysis showed N stage and clinical stage were associated with OS, smoking, clinical stage, surgical margins, and Ki-67 index were associated with RFS. There were no significant differences in preoperative IC or direct surgery, TLM, or TORS. Cox analyses showed smoking and surgical margins were independent prognosis factors for RFS., Conclusions: The positive margin, Ki-67 index ≥40% and P53(+)&Ki-67 index ≥40% are worse factors affecting recurrence for SGLC patients. Both smoking and surgical margins are independent prognostic factors affecting recurrence., (© 2024 The Authors. Cancer Reports published by Wiley Periodicals LLC.)

Objective: To observe the clinical effect of placing heterogeneous acellular dermal matrix membrane for laryngeal cavity wound healing after CO2 laser Type-Ⅴa cordectomy for glottic carcinoma. Methods: Thirty-five patients with bilateral vocal cord laryngeal cancer who underwent endoscopic CO2 laser surgery at the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University from March 2018 to December 2019 were selected and divided into 2 groups, including 18 patients in the study group and 17 patients in the control group. The control group was simply placed silicone tube stent, while in the study group, heterogeneous acellular dermal matrix membrane was coated with silicone tube stent. The postoperative laryngeal wound repair and clinical manifestations were observed and compared between the two groups. Results: Compared postoperative laryngeal wound after 6 months: no patients in the study group had granulation tissue, whereas 4 patients in the control group had granulation tissue; 3 patients in the study group developed moderate to severe tissue adhesion, while 9 patients in the control group; 10 patients in the control group developed 2nd to 4th degree laryngeal obstruction, compared with only 4 patients in the study group. Conclusion: The primary placement of ADM can reduce laryngeal granulation tissue and tissue adhesion after CO2 laser Type-Ⅴa cordectomy for laryngeal cancer, and may reduce the occurrence of postoperative laryngeal obstruction., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)
