Abstract Background Over the past decade, therapeutic options in head and neck supraglottic squamous cell carcinoma have constantly evolved. The classical total laryngectomy has been partially replaced by alternative organ- and function-sparing techniques with the same prognosis but less morbidity, such as Radiotherapy, Transoral Laser Microsurgery (TLM) and Trans-Oral Robotic Surgery (TORS). Up to now, a prospective comparison of these innovant techniques has not been conducted. Methods/design We will conduct an original international multicentric prospective nonrandomized clinical trial to compare the efficacy between these treatments (Arm 1: Radiotherapy ± chemotherapy; Arm 2: TLM and Arm 3: TORS) with 4 classes of outcomes: quality of life (QoL), oncological outcomes, functional outcomes and economic resources. The population will include cT1-T2 /cN0-N1/M0 supraglottic squamous cell carcinoma. The primary outcome is a Clinical Dysphagia QoL evaluation assessed by the MD Anderson Dysphagia questionnaire. Secondary outcomes include others QoL evaluation, oncological and functional measures and cost parameters. The sample size needs to reach 36 patients per arm (total 108). Discussion In the current literature, no prospective head-to-head trials are available to compare objectively these different treatments. With the increase of highly efficient treatments and the increase of oncological survival, it is imperative also to develop management strategies that optimize QoL and functional results. We will conduct this innovate prospective trial in order to obtain objective data in these two main issues. Trial registration NCT05611515 posted on 10/11/2022 (clinicaltrial.fgov).

Background: In oral and oropharyngeal squamous cell carcinoma (SCC), sentinel node biopsy (SNB) was described as a reliable and reproductive alternative to elective neck dissection for the staging of clinical N0 T1-T2 patients. The SNB technique in supraglottic laryngeal SCC was successfully described in small series. The aim of this study is to analyze retrospectively the results of SNB technique in supraglottic SCC in CHU Godinne, to determine if the technique is reliable and may be proposed in a future multicentral prospective trial., Methods: The study involved a retrospective analysis of 39 patients who underwent surgery between 2003 and 2019 at CHU Godinne. All patients presented with clinical N0 neck status. The SNB procedure included general anesthesia, 99-technetium colloid peritumoral injection, and lymphoscintigraphy. The hand-held gamma probe was utilized for SNB after tumoral resection during the same operating session. Out of 39 patients, 36 underwent SNB as the sole staging tool, while 3 patients received SNB in combination with elective neck dissection. Primary outcome was the 2-years neck recurrence-free survival (RFS). Secondary outcomes were the 2- and 5-years disease-specific survival (DSS). Additionally, sensitivity and negative predictive value (NPV) of the SNB technique were analyzed., Results: Sentinel nodes were successfully identified in all 39 patients. An average of 4 nodes excised per patient. Positives SN were detected in 23% (9 in 39) cases, leading to subsequent selective neck dissection. Two cases of neck recurrence were observed, both considered as false negatives, occurring after an average of 3.5 months. Th median follow-up period was 48 months with a 2-year RFS of 95%. Sensitivity and NPV of the SNB technique were found to be 82% and 94%, respectively. Two and five years DSS were 84% and 71.7%, respectively., Conclusions: The results suggest that SNB in T1-T2 supraglottic SCC is a feasible and reliable technique for managing the neck in N0 early-stage patients. However, to establish its oncological equivalence with selective node dissection, further prospective and comparative studies are warranted. The findings of this study underscore the importance of ongoing research in refining and validating the role of SNB in the management of supraglottic SCC, potentially paving the way for more widespread adoption in clinical practice., (© 2024 Wiley Periodicals LLC.)

Background: Recurrent respiratory papillomatosis (RRP) is a currently incurable benign neoplasm caused by human papilloma virus (HPV) infection. It usually reduces voice, respiratory, and general quality of life, and is sometimes life-threatening. Patients usually need repeated operations. The use of adjuvant bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor A, has been described in several case reports, with a good efficacy and safety profile., Methods: We report the cases of five patients with aggressive RRP who were treated with adjuvant systemic bevacizumab in a single Belgian tertiary center., Results: A complete response was achieved in four patients after a median of 4.5 months, and a partial response in one. In all cases, the number of surgeries was drastically reduced, and quality of life improved. Toxicity was easily managed., Conclusions: Systemic bevacizumab seems to be an effective and safe adjuvant treatment for aggressive RRP., (© 2023 The Authors.

Purpose: Spasmodic dysphonia (SD) or laryngeal dystonia is as a rare vocal disorder characterized by involuntary action-induced endolaryngeal contraction. In the last decade, botulin toxin injection has become the standard treatment in adductor spasmodic dysphonia necessitating repetitive injections. The purpose of this study is to analyze retrospectively data from patients treated with the minimal-invasive transoral radiofrequency-induced thermotherapy (RFITT) of the terminal branches of the recurrent nerve., Methods: Between 2009 and 2015, 11 patients (six females and five males aged from 32 to 91 years) with adductor SD were treated with RFITT. Pre-operative and post-operative vocal assessments (VHI-30, GRBASI, and acoustic-aerodynamics measurements), number of surgical revisions, delay between procedures, and post-operative complications were recorded. Statistical analyses were carried out on the first vocal assessment performed 2-8 weeks after the first procedure., Results: Based on available data from ten patients, voice handicap index (VHI) showed improvement with a mean value of -17.7 points (p-value (pval) = 0.014, adjusted p-value (adj pval) = 0.21); instability has also revealed improvement in six patients (pval = 0.05, adj pval = 0.31). Four patients underwent only one procedure including one patient showing still long-term beneficial results after 5 years of follow-up. Other patients required one to three new procedures with an average time between procedures of 15.3 months. Over 24 surgeries performed on a total of 11 patients, one definitive treatment-related severe adverse event was reported., Conclusion: Thanks to long-lasting effect, repetitive treatments are less frequent compared to botulin toxin therapy. In our opinion, RFITT is a promising alternative to botulin toxin as a second-step procedure in case of toxin resistance or patient's lack of compliance., (© 2022.

Purpose: With the development of minimal invasive procedure, trans-oral robotic surgery (TORS) is expanding in the field of ENT. Most reviews focus on oropharyngeal and laryngeal (supra-glottic) localization. We report here the feasibility and outcomes of TORS hypopharyngectomy (TORSH) for selected patients with hypopharyngeal tumor., Methods: Between September 2009 and July 2017, 22 patients, retrospectively included, underwent TORSH with curative intent., Results: From 22 successful hypopharyngectomy, no conversion to open procedure was needed. Three patients (13%) presented a post-operative bleeding and were managed by surgical revision. No fistula was encountered. The 3-year overall survival and disease-specific survival rates were 54 and 92%, respectively. Patients started oral feeding after an average of 7 days. Naso-gastric feeding tubes were removed after a median period of 16 days. Two patients (9%) needed a transient gastrostomy (< 1 year). Three patients (13%) received a transient tracheostomy (< 2 months). Median hospitalization stay was 13 days., Conclusions: TORSH is a safe technique. Patients' outcomes are favorable and the post-operative morbidity is reduced compared to open neck approach. Hospitalization length and safe swallowing time are reduced.

Background: When a patient is seen with a newly diagnosed oropharyngeal squamous cell carcinoma, it remains unclear to the treating physicians how fast the tumor growth rate is., Methods: From patients with oropharynx squamous cell carcinoma treated by radiotherapy, the investigators selected comparable diagnostic CT-scan (DiCT) and radiotherapy planning CT-scan (RtCT). Tumor and pathological lymph node volumes were measured in order to calculate tumor progression., Results: From the selection of 19 patients, the mean absolute tumor progression rate was 0.23 ± 0.2 cm 3 /d and mean relative progression rate was 1.84 ± 1.64%/d. Mean tumor doubling time is 286 days (range 7-1282 days), demonstrating a wide range of tumor growth pattern. Significant tumor progression (>20%) between DiCT and RtCT was shown in 73% of patients, and 53% of the patients were seen a tumor progression of >50% within a mean waiting time of 42.1 days. Kaplan-Meier curves showed a non-significative link between fast progression tumors (>1%/d) and higher risk of recurrence (HR: 2.2; P = .23)., Conclusions: Tumor progression can be assessed based on DiCT and RtCT. Treatment delay should be avoided at all cost. Different growth patterns were evidenced. For the fast-growing tumors subgroup, pejorative clinical outcomes were suggested. Prospective studies are needed to confirm a link between fast-growing tumors and higher risk for recurrence., (© 2019 Wiley Periodicals, Inc.)

Objective: The aim of our study is to demonstrate our technique for performing transoral robotic surgical total laryngectomy (TORS-TL) with the use of the da Vinci robotic system., Materials and Methods: We provide a comprehensive description of the TORS-TL operative techniques. Two fresh-frozen human cadavers were selected after ethics approval to describe the appropriate step-by-step surgical resection. We adopted a 5-step procedure that was later applied to 2 of our patients. The first patient presented initially with a squamous cell carcinoma (SCC) in the laryngeal glottis area. A lack of clinical response to initial treatment by chemoradiotherapy led to the decision of performing salvage TL surgery. The second patient had a previous history of head and neck SCC (HNSCC); he had no recurrence of his primary tumor but suffered significantly from postoperative breathing and swallowing difficulties due to severe laryngeal incompetence., Results: TORS-TL was successfully performed in all cases. The operative time for the cadavers was approximately 65 and 55 min, respectively. It was significantly longer for the patients, 210 and 235 min, respectively, despite the fact that exactly the same steps were followed throughout all procedures. There were no intra- or postoperative complications or surgical morbidity related to the use of the da Vinci system., Conclusion: TORS-SL for SCC was performed in a safe, reliable, and smooth manner and was shown to be successful in treating our patients. We thus believe that our step-by-step surgical technique for TORS-SL is efficient and reproducible., (© 2018 S. Karger AG, Basel.)

Epiphora is a frequent reason for ophthalmologic consultation. Among the multiple causes, obstructions of the lacrimal excretory system are common. Sacal and postsacal obstructions are much more frequent than presacal obstructions. Obstruction at the level of the Hasner's valve is rare and likely underestimated. The authors report the clinical history and the imaging of 3 patients with a cystic dilation of the distal end of the nasolacrimal duct (NLD). These patients were easily managed by an ENT surgeon. In one case, the surgery consisted of an endonasal DCR where in the 2 other cases, a marsupialisation of the cystic expansion of the nasolacrimal duct was successfully performed with the micro- debrider. The authors review the world literature on this specific topic. They conclude that a coronal sinus CT scan and an inferior meatus endoscopy should be included in the ophthalmologic work-up performed in all cases of low obstruction of the lacrimal system. When there is a dilation of the distal end of the NLD the marsupialisation of the cystic expansion in the inferior meatus is the option of treatment instead of performing a DCR. ENTs must play a role in the assessment and treatment of low obstructions of the lacrimal excretory system.
