Background: Thyroid gland is the largest and most vascular structure among the endocrine glands. The recurrent laryngeal nerve and the superior laryngeal nerve are closely related to the thyroid gland; these nerves control voice and are vital in breathing. Anatomical preservation of the recurrent laryngeal nerve (RLN) is the gold standard in thyroid surgery. Visual identification of RLN has decreased the rates of permanent RLN palsy during thyroid and parathyroid operations. Prior knowledge about the branching patterns will help in predicting and preventing injury to the nerve during thyroid surgery. Aim and objectives: The aim of the study is to observe the terminal branching pattern of recurrent laryngeal nerve before its entry into the larynx. Methods: An observational study with 50 participants who fulfilled the inclusion and exclusion criteria were enrolled in the study. After a complete evaluation and pre-anaesthetic checkup, the patients were operated and intraoperative findings of RLN branching were recorded and compared for the study. Results: In our study, out of the 50 patients who underwent thyroid surgery during the course of the study, right-sided RLN branching was demonstrated in 25 patients (21 right hemithyroidectomy and 4 total thyroidectomy). Ten patients had RLN bifurcation, 7 had trifurcation, 5 had numerous branches, and 3 with no branching pattern were noted. Similarly, out of 29 patients (25 left hemithyroidectomy and 4 total thyroidectomy) in whom left-sided RLN branching was studied, bifurcation was seen in 10 patients, trifurcation in 12 patients, and multiple branching was observed in 7. Conclusion: The anatomical variations seen in RLN may increase the risk of vocal cord palsy due to its injury. Anatomical variations are categorized according to the original direction of the RLN and the number of terminal branches in the larynx. This classification aids in the identification and preservation of its branches, hence facilitating a safer thyroidectomy. [ABSTRACT FROM AUTHOR]

Introduction: Graves' disease (GD) is the most common cause of hyperthyroidism in children and adolescents. Data regarding pediatric GD in Indonesia are limited and pose challenges to diagnosing and treating the patients. In many aspects the clinical presentation of GD in children and adolescents resembles that of the adult population. There are three treatments for pediatric GD: anti-thyroid drugs, radioiodine ablation, and thyroidectomy. Although surgery is gaining acceptance as the definitive first-line treatment for children with GD, several studies examining pediatric populations have shown high complication rates. This study aims to describe a series of pediatric GD cases from a tertiary care center over an eight-year period. Presentation of Cases: Retrospective data of five patients with hyperthyroidism diagnosed with GD between 2014 and 2022 were reviewed. Clinical presentation, diagnosis, therapies, and short-term postoperative outcomes of GD were analyzed. All five GD patients presented with neck lumps. Low TSH levels and elevated FT4 levels were found in all patients preoperatively. Total thyroidectomy was performed in all patients, while one patient had lymphadenectomy concurrently. Histopathologic examination confirmed a diagnosis of GD in all patients. All patients in this study experienced postoperative complications such as hoarseness, while only three patients had hypocalcemia as a complication. Discussion: Total thyroidectomy in pediatric patients remains challenging. The euthyroid condition in patient prior to surgery is recommended to avoid the risk of thyroid storm during surgery, but a few studies have revealed that there is no difference in outcomes for hyperthyroid individuals. Close postoperative surveillance for complications of total thyroidectomy is necessary. Conclusions: Results of this study showed that pediatric GD patients had the same symptoms of hyperthyroidism as adults with all patients complained of neck lumps. Total thyroidectomy is the definitive therapy for GD in pediatrics as well as in adults. The minority of patients will experience transient and benign morbidities, with hoarseness of the voice being the most common transient postoperative morbidity. In performing total thyroidectomy, meticulous surgery and good anatomical recognition are required to avoid postoperative complications. So that, follow-up of post-total thyroidectomy in pediatric GD patients needs to be done. [ABSTRACT FROM AUTHOR]

A 44-year-old patient presented with hoarseness of voice and a polypoidal lesion on the left vocal cord. Complete excision was done. To our knowledge, this is the second reported case of molluscum contagiosum of the vocal cords. It should be considered as a differential diagnosis of a vocal cord lesion. [ABSTRACT FROM AUTHOR]

Purpose: Hoarseness and voice problems are one of the chronic conditions experienced by children. The aim of this study was to investigate the prevalence of hoarseness, possible risk factors and effects of the remediation of school buildings to the prevalence of hoarseness among school children. Methods: The material was gathered from all the schools in a large city in the south of Finland and the collection method used was an e-mail survey sent to the parents of the pupils and a simultaneous survey sent to the personnel in the schools. Results: All 51 schools participated, and 5889 pupils returned the questionnaire (39%). The exposure data was obtained from two building experts who knew the repair history of the schools. A subjective estimation of the quality of the indoor air was obtained from teachers and the parents. The overall prevalence of hoarseness among pupils was 6.3%; prevalence being higher in unrepaired school buildings than in schools in a good condition or buildings with a thorough remediation. Hoarseness was associated with asthma and allergies, several respiratory symptoms, and respiratory infections. Exposure to tobacco smoke increased the risk, and consumption of caffeine containing drinks seemed to reduce the risk. Noise, stuffiness of the indoor air and microbial smells correlated strongly with the occurrence of hoarseness in a logistic regression model when controlled for age, gender, asthma, passive smoking, and caffeine consumption. Conclusions: We recommend renovations in school buildings with the aim of providing better acoustics, sufficient ventilation, and a reduction in exposure to moisture damage microbes.

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. [ABSTRACT FROM AUTHOR]

Background: The conventional double-lumen tube (DLT) insertion method requires a rotatory maneuver that was developed using direct laryngoscopy and may not be optimal for video laryngoscopy. This study compared a new non-rotatory maneuver with the conventional method for DLT insertion using video laryngoscopy. Methods: Patients scheduled for thoracic surgery requiring one-lung ventilation were randomly assigned to either the rotating (R) or non-rotating (NR) method groups. All patients were intubated using a customized rigid J-shaped stylet, a video laryngoscope, and a left-sided silicone DLT. The conventional rotatory maneuver was performed in the R group. In the NR group, the stylet was inserted with its tip oriented anteriorly (12 o'clock direction) while maintaining the bronchial lumen towards the left (9 o'clock direction). After reaching the glottic opening, the tube was inserted using a non-rotatory maneuver, maintaining the initial orientation. The primary endpoint was the intubation time. Secondary endpoints included first-trial success rate, sore throat, hoarseness, and airway injury. Results: Ninety patients (forty-five in each group) were included. The intubation time was significantly shorter in the NR group compared to the R group (22.0 [17.0, 30.0] s vs. 28.0 [22.0, 34.0] s, respectively), with a median difference of 6 s (95% confidence interval [CI], 3–11 s; p = 0.017). The NR group had a higher first-attempt success rate and a lower incidence of sore throats. Conclusions: The non-rotatory technique with video laryngoscopy significantly reduced intubation time and improved first-attempt success rate, offering a viable and potentially superior alternative to the conventional rotatory technique.

Purpose: Lipoid proteinosis (LP) or Urbach-Wiethe disease (OMIM 247100) is a rare syndrome characterised by early vocal folds infiltration and subsequent multi-organ involvement. LP is often unrecognised and its associated hoarseness is overlooked. The main objective of the study was to investigate hoarseness in LP and implement a diagnosis among otolaryngologists. Methods: PubMed/MEDLINE and OMIM databases were systematically searched. Authors concentrated the search on published articles starting from the discovery of the pathogenesis of LP by Hamada et al. in 2002. Only cases in which a diagnosis was reported both clinically and through biopsy and/or genetic molecular testing were included. Characteristics of the LP cases were extracted from each included study. Results were obtained through Generalized Estimating Equations. Results: The search strategy yielded 217 articles, of which 74 (34.1%) met the selection criteria. A total of 154 cases were included. Hoarseness was described in all LP cases and clearly stated as the onset symptom in 68.8%. The onset was on average at 19 months of age (CI: 3.00–20.00), while the mean age at diagnosis was 15 years (CI: 10.00–30.00). Therefore, the diagnostic delay amounted to 13.42 years (CI: 8.00–23.83). Hoarseness alone was responsible for an LP diagnosis in only 14.3% of cases. In 43.5% of cases, genetic analysis of the ECM1 gene was performed and exon 6 was the most frequently altered portion. Conclusion: Analysing the largest number of published cases, the study underlined that hoarseness is the key symptom for diagnosing LP since early childhood, though frequently overlooked.

Injection laryngoplasty (IL) has become a mainstay in the treatment of unilateral vocal fold paralysis due to technical ease and avoidance of open surgery. The duration of IL effect depends on the injected material and has not been defined clearly. We aimed to define the effective duration of IL and to investigate the associated factors. Fifty-nine patients who underwent IL for unilateral vocal fold paralysis were included. IL was performed using a cricothyroid membrane approach under local anesthesia. During follow-up, in cases that developed subjective hoarseness with objective glottic insufficiency, a second IL was performed, and loss of IL effect was recorded. The duration of IL was analyzed using Kaplan-Meier estimates, and the associations between duration of effect and various factors such as postinjection voice therapy, injected material, and cause of paralysis were investigated using log-rank test. Of 59 patients, 20 (33.9 %) received a second IL. The median time interval between the first and second IL was 3.3 months (95% CI, 0.4∼27.8 months). The mean duration of effect after IL was 42.5 months (95% CI, 32.1∼52.9 months), and the rate of persisting effect was 63.4% at 1-year after IL (1-year effect rate) and 59.4% at 2 years after IL. The 1-year effect rate was 80.8% in cases with postinjection voice therapy and 57.8% in those without postinjection voice therapy (P = 0.084). Injected material, DM, HTN, patient age and sex, and cause of paralysis had no effect on the 1-year effect rate. The mean duration of IL effect was 42.5 months, and the rate of persisting effect was 63.4% at 1-year after IL. There were no significant factors affecting the duration of effect, although the duration tended to be slightly longer in cases with postinjection voice therapy. Further study with a prospective, randomized design is needed. [ABSTRACT FROM AUTHOR]

To determine the relationship between working conditions, especially room acoustics, with voice symptoms and voice-related quality of life among Colombian school and college teachers during online classes in times of COVID-19 pandemic. Exploratory cross-sectional study. Participants were thirty-two primary, secondary and university Colombian teachers, who were invited to fill in an online survey about working conditions and voice symptoms during online classes in times of COVID-19 pandemic. In the statistical analysis, four dependent variables and eight independent variables were defined. We used Generalized Linear Model with a Gamma distribution and Binary Logistic Regression to determine the association between voice with working conditions. High reverberation time and stress during online classes in times of the COVID-19 pandemic reduced slightly the VRQOL scores. For Factor 3 of the VFI, high reverberation time and months teaching online classes were associated at the multivariate analysis. Stress and years of experience were statistically associated with an increased odds of reporting hoarseness. Similar to pre-COVID-19, teachers with online classes during the COVID-19 pandemic are affected by two work-related factors namely high reverberation time and stress. These two factors are increasing their likelihood of reporting hoarseness and having lower voice-related quality of life, which may confirm the relationship between reverberation, stress, and voice also during online classes. This highlights the need of implementing workplace vocal and mental health programs to decrease the occurrence of voice problems among teachers in times of and post-COVID-19 pandemic.

Aim: Postoperative sore throat (POST) is a commonly encountered and significant complication following anesthesia, which can adversely affect the quality of a patient's recovery. Many factors contribute to the development of POST. Controlled hypotension (CH) is a surgical technique used to reduce blood flow, improve visibility, and shorten procedure time by safely lowering blood pressure. In this study, we aimed to investigate the effects of CH on POST, coughing, hoarseness, and vomiting in patients undergoing surgery in a supine position with a fixed endotracheal cuff pressure. Material and Method: A total of 124 patients, aged between 18 and 65 years, classified as American Society of Anesthesiologists (ASA) class I-II and scheduled for elective surgical procedures, were included in the study. The patients were divided into two groups: Group N (n=65), consisting of normotensive individuals, and Group H (n=59), which included patients subjected to CH. In both groups, the endotracheal cuff pressure was manually set to 25 cmH2O using a cuff pressure manometer. CH was achieved in Group H by administering glyceryl trinitrate (nitroglycerin) infusion, maintaining the mean arterial pressure (MAP) within the range of 55-65 mmHg. Patients were assessed for POST, coughing, hoarseness, and vomiting at postoperative 15 minutes, 2, 6, 12, and 24 hours. Results: Demographic data, smoking status, ASA scores, surgical and anesthesia durations were similar between the groups. Statistically significant differences were observed between the groups in the numeric rate scores (NRS) for throat pain at 15 minutes and 2 hours, as well as hoarseness scores at 2 and 6 hours. The groups were similar regarding vomiting rates and cough scores. Conclusion: In this study investigating the impact of CH on sore throat, we observed an increased incidence of POST and hoarseness in patients subjected to CH. [ABSTRACT FROM AUTHOR]

Background: Thyroid Hydatid Cyst (THC), a pathological state induced by the larval form of Echinococcus granulosus, represents a multifaceted clinical entity with nonspecific symptoms, making both diagnosis and treatment intricate. The current understanding of THC's attributes is somewhat limited. To gain a broader perspective on the disease's clinical and epidemiological characteristics, we have systematically reviewed the existing literature. Methods: We performed an extensive review of articles on THC across four key scientific databases: PubMed, Scopus, Web of Science, and Google Scholar. Our study encompassed all patients diagnosed with THC through post-surgical pathology or Fine Needle Aspiration Cytology (FNAC) examinations, extracting clinical, epidemiological, and therapeutic data of THC patients from publications up to October 2023. Results: From 770 articles, 57 met our criteria, detailing 75 THC patients. The gender ratio was 2.36 females per one male. The patients averaged 36.1 years old, with common symptoms including neck mass, hoarseness, shortness of breath, and dysphagia. The left lobe was involved in most patients, and only 21.3% had extrathyroidal involvement. Cysts averaged 36.4 mm in diameter, with cystic nodules being the most frequent imaging finding (91.2%). Serological tests were performed for 42.6% of cases, of which 62.5% were positive. Surgery was undertaken in 71 patients (94.6%). Conclusion: Cystic echinococcosis (CE) of the thyroid should be considered as part of the differential diagnosis in patients with cervicofacial mass, especially in endemic countries. The present study provides reliable data to improve our understanding of the features of the disease for a better diagnosis and management. [ABSTRACT FROM AUTHOR]

Introduction: Carotid endarterectomy is performed for patients with symptomatic carotid artery occlusions. Surgery can be performed under general and regional anesthesia. Traditionally, surgery is performed under deep cervical plexus block which is technically difficult to perform and can cause serious complications. This case series describes 5 cases in which an intermediate cervical plexus block was used in combination with a superficial cervical plexus block for Carotid endarterectomy surgery. Methods: Five patients who were classified as American Society of Anesthesiologists 2–3 were scheduled for Carotid endarterectomy due to symptoms and more than 70% occlusion of the carotid arteries. The procedures were carried out in the University Teaching Hospital- Peradeniya, Sri Lanka. All patients were given superficial cervical plexus block followed by intermediate cervical plexus block using 2% lignocaine and 0.5% plain bupivacaine. Results: Adequate anesthesia was achieved in 4 patients, and local infiltration was necessary in 1 patient. Two patients developed hoarseness of the voice, which settled 2 h after surgery. Hemodynamic fluctuations were observed in all 5 patients. No serious complications were observed. All 5 patients had uneventful recoveries. Discussions: Regional anesthesia for CEA is preferable in patients who are medically complicated to undergo anesthesia or in patients for whom cerebral monitoring is not available. Intermediate cervical plexus block is described for thyroid surgeries in literature, but not much details on its use for carotid surgeries. Deep cervical plexus blocks has few serious complications which is not there with the use of ICPB making it a good alternative for CEA surgeries. Conclusions: Superficial cervical plexus block and intermediate cervical plexus block can be used effectively for providing anesthesia for patients undergoing Carotid endarterectomy. It is safe and easier to conduct than deep cervical plexus block and enables monitoring of cerebral function. [ABSTRACT FROM AUTHOR]

Patients with Voice problems are frequently encountered in clinics. There is no tool available in Punjabi language for evaluation of impact of voice disorder on patient's life. The aim of this study was to adapt Voice Handicap Index in Punjabi language and to obtain validity, reliability and consistency of the developed tool. The study also aims to compare the scores of VHI-Punjabi between patients with voice problems and asymptomatic age-matched controls. The study follows qualitative research design with purposive sampling. The study was conducted at the Audiology and SLP unit of ENT, Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab. A total of 200 subjects in the age group of 20–50 years were included, 100 each in study and control group. Combination of reverse translation, committee, and bilingual models were used for development of VHI-Punjabi. The construct validity was very good (r = 0.91). A statistically significant difference (p < 0.001) was obtained between the study group and control group in all the subtest scores and on the total scores of VHI-Punjabi. Statistical significant correlation is found in two administrations of VHI-Punjabi after a gap of 2 weeks in both study group and control group (p < 0.001). To find the internal consistency of VHI-Punjabi, Chronbach alpha was calculated, which came to be 0.97. The internal consistency was high. The results of the present study indicate that VHI-Punjabi is a valid and reliable tool that can be used for evaluation of patients with different types of voice problems. [ABSTRACT FROM AUTHOR]

Emergency airway management is critical in trauma care. Cricothyroidotomy (CRIC) is a salvage procedure commonly used in failed endotracheal intubation (ETI) or difficult airway cases. However, more data is needed regarding the short and long-term complications associated with CRIC. This study aimed to evaluate the Israel Defense Forces experience with CRIC over the past 2 decades and compare the short-term and long-term sequelae of prehospital CRIC and ETI. Data on patients undergoing either CRIC or ETI in the prehospital setting between 1997 and 2021 were extracted from the Israel Defense Forces trauma registry. Patient data was then cross-referenced with the Israel national trauma registry, documenting in-hospital care, and the Israel Ministry of Defense rehabilitation department registry, containing long-term disability files of military personnel. Of the 122 patients with short-term follow-up through initial hospitalization, 81% underwent prehospital ETI, while 19% underwent CRIC. There was a higher prevalence of military-related and explosion injuries among the CRIC patients (96% versus 65%, P = 0.02). Patients who underwent CRIC more frequently exhibited oxygen saturations below 90% (52% versus 29%, P = 0.002). Injury Severity Score was comparable between groups.No significant difference was found in intensive care unit length of stay and need for tracheostomy. Regarding long-term complications, with a median follow-up time of 15 y, CRIC patients had more upper airway impairment, with most suffering from hoarseness alone. One patient in the CRIC group suffered from esophageal stricture. This retrospective comparative analysis did not reveal significant short or long-term sequelae among military personnel who underwent prehospital CRIC. The long-term follow-up did not indicate severe aerodigestive impairments, thus suggesting that this technique is safe. Along with the high success rates attributed to this procedure, we recommend that CRIC remains in the armamentarium of trauma care providers. The findings of this study could provide valuable insights into managing difficult airway in trauma care and inform clinical decision-making in emergency settings. [ABSTRACT FROM AUTHOR]

Background: The neuromuscular blocking agent mivacurium can be used during anesthesia to facilitate tracheal intubation. Data on onset time, duration of action, and effect on intubating conditions in patients 80 years and older are however limited. We hypothesized that onset time and duration of action of mivacurium would be longer in elderly patients than in younger adults. Methods: This prospective observational study included 35 elderly (≥80 years) and 35 younger (18–40 years) patients. Induction of anesthesia comprised fentanyl 1–3 μg kg−1 and propofol 1.5–2.5 mg kg−1 and propofol and remifentanil for maintenance. Acceleromyography was used for monitoring neuromuscular blockade. The primary outcome was onset time defined as time from injection of mivacurium 0.2 mg kg−1 to a train‐of‐four (TOF) count of zero. Other outcomes included duration of action (time to TOF ratio ≥0.9), intubating conditions using the Fuchs‐Buder scale and the intubating difficulty scale (IDS), and occurrence of hoarseness and sore throat postoperatively. Results: No difference was found in onset time comparing elderly with younger patients; 219 s (SD 45) versus 203 s (SD 74) (difference: 16 s (95% CI: −45 to 14), p =.30). Duration of action was significantly longer in elderly patients compared with younger patients; 52 min (SD 17) versus 30 min (SD 8) (difference: 22 min [95% CI: 15 to 28], p <.001). No difference was found in the proportion of excellent intubating conditions (Fuchs‐Buder); 31/35 (89%) versus 26/35 (74%) (p =.12) or IDS score (p =.13). A larger proportion of younger patients reported sore throat 24 h postoperatively; 34% versus 0%, p =.0002. No difference was found in hoarseness. Conclusion: No difference in onset time of mivacurium 0.2 mg kg−1 was found comparing elderly and younger patients. However, elderly patients had significantly longer duration of action. No difference was found in intubating conditions. [ABSTRACT FROM AUTHOR]

Introduction: Recurrent laryngeal nerve palsy is a rare but important complication after endarterectomy (CEA). The impact on voice quality after this procedure is also important. The aim of the study was to assess voice quality and vocal cord function after CEA. Material and Methods: 200 patients were enrolled in the study. Inclusion criteria were indications for CEA and patient consent to the procedure. Endoscopic examination of the larynx was performed before the procedure, immediately after the procedure, on the 2nd day after the procedure, then 3 month and 6 months after the procedure. Voice was assessed by maximum phonation time (MPT), GRBAS scale, Voice Handicap Index (VHI) and the Voice-Related Quality of Life (V-RQOL) questionnaire. Results: In the study group, the results on the GRBAS scale were significantly worse and the average MPT was shorter compared to the control group. In the V-RQOL assessment, patients rated their voice as fair or good, significantly more often noticed that they had difficulty speaking loudly and being heard, and that they felt short of air when speaking. In VHI-30, the total score was significantly higher in the study group compared to the control group. Voice disorders after the procedure were reported by 68 patients, while a disorder of the recurrent laryngeal nerve was observed immediately after the procedure in 32 patients. Most vocal cord disorders were transient. Ultimately, 3% of patients were diagnosed with vocal cord paralysis. Conclusion: Cranial nerves paralysis, including the recurrent laryngeal nerve, are a common complication after CEA. Majority the paralysis is transient, but requires appropriate diagnostic and therapeutic procedures. Vocal cord evaluation is a non-invasive and widely available examination and should be performed pre- and postoperatively after all neck surgeries. The incidence of voice disorders after CEA significantly affects the quality of life of patients and requires voice rehabilitation and patient care with psychological support. [ABSTRACT FROM AUTHOR]

Bamboo nodes (BNs) is a rare disease detected in the Department of Otorhinolaryngology. Here, we reported two cases of BNs, highlighting a potential association of BNs with autoimmune diseases. Upon presentation, the primary concerns of both patients were hoarseness and foreign body sensation. In both cases a co-existence between BNs and an autoimmune disease was identified. In one case, BNs were initially diagnosed while undifferentiated connective tissue disease was later identified by serological testing. In contrast, the other patient did not show any BN-related symptom until two months of therapy for undifferentiated connective tissue disease. Both cases received oral administration of medicines for immunotherapy, with one taking voice training. Both recovered from the larynx symptoms after 10 to 12 months of therapy. This report reminded us of the potential association of BNs with autoimmune diseases. Voice training may be an effective adjuvant intervention for the treatment of BNs.

Evaluating hoarseness after cardiac surgery could be crucial to detecting decreased swallowing function. However, objectively detecting hoarseness has been difficult in daily clinical practice of cardiovascular domains, because it is only performed by skilled voice treatment specialists. Recently, some evaluating methods of hoarseness using artificial intelligence with its recent development have been reported. This exploratory study aimed to investigate the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) scale items using an iPhone application "GRBASZero" for detecting aspiration following cardiac surgery.

Objective: To systematically review vagus nerve stimulation (VNS) studies to present data on the safety and efficacy on motor recovery following stroke, traumatic brain injury (TBI), and spinal cord injury (SCI). Methods: Data sources: PubMed, EMBASE, SCOPUS, and Cochrane. Study selection: Clinical trials of VNS in animal models and humans with TBI and SCI were included to evaluate the effects of pairing VNS with rehabilitation therapy on motor recovery. Data extraction: Two reviewers independently assessed articles according to the evaluation criteria and extracted relevant data electronically. Data synthesis: Twenty-nine studies were included; 11 were animal models of stroke, TBI, and SCI, and eight involved humans with stroke. While there was heterogeneity in methods of delivering VNS with respect to rehabilitation therapy in animal studies and human non-invasive studies, a similar methodology was used in all human-invasive VNS studies. In animal studies, pairing VNS with rehabilitation therapy consistently improved motor outcomes compared to controls. Except for one study, all human invasive and non-invasive studies with controls demonstrated a trend toward improvement in motor outcomes compared to sham controls post-intervention. However, compared to noninvasive, invasive VNS, studies reported severe adverse events such as vocal cord palsy, dysphagia, surgical site infection, and hoarseness of voice, which were found to be related to surgery. Conclusion: Our review suggests that VNS (non-invasive or invasive) paired with rehabilitation can improve motor outcomes after stroke in humans. Hence, VNS human studies are needed in people with TBI and SCI. There are risks related to device implantation to deliver invasive VNS compared to non-invasive VNS. Future human comparison studies are required to study and quantify the efficacy vs. risks of paired VNS delivered via different methods with rehabilitation, which would allow patients to make an informed decision.

Carcinoma showing thymus-like differentiation (CASTLE) is a rare malignant tumor that accounts for 0.1%–0.15% of all thyroid cancers. More than half of the patients have tumor extension to adjacent organs, including the recurrent laryngeal nerve, trachea, and esophagus. The diagnosis of CASTLE is based on histology and immunohistochemistry. A 58-year-old female patient complained of hoarseness for one and half years. Right side vocal cord palsy was diagnosed by fiberscopy. Thyroid sonography revealed right thyroid tumors, which were reported to be papillary thyroid carcinoma through FNAC. Total thyroidectomy with central lymph node dissection was performed. Pathologist found 2 isolated malignancy tumors. One patient in the right thyroid lobe had papillary thyroid carcinoma features. The other extrathyroid tumor seemed to be separated from the first tumor and invaded the thyroid capsule. After multiple immunohistochemical studies, PTC synchronous CASTLE was the final diagnosis. Coexisting PTC and CASTLE is very rare. This is the first report to describe a case showing PTC at first, while subsequent pathologic examination revealed the presence of CASTLE in addition to PTC. Since the prognosis of CASTLE is favorable, the treatment is different from other aggressive thyroid cancers, such as poorly differentiated or anaplastic thyroid carcinoma. [ABSTRACT FROM AUTHOR]

Esophageal duplication cysts are rare congenital noncancerous growths. Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended. However, when the cyst is situated in the upper mediastinum, surgical excision becomes technically challenging. Here, we report a case of an obese female patient with esophageal duplication cyst in the upper mediastinum who underwent successfully robotic‐assisted complete removal of the cyst. A 50‐year‐old woman presented to a local clinic with a persistent cough and hoarseness lasting 4 months. A computed tomography scan revealed a large cystic tumor in the upper mediastinum, causing displacement of the trachea. The resection of the cystic tumor was safely performed with robotic assistance. The use of robotic system for the removal of esophageal duplication cyst is technically safe and feasible. [ABSTRACT FROM AUTHOR]

The lightwand is a valuable device for managing the airways of patients with neck immobilization due to its ease of minimal neck movement. For lightwand intubation, adopting a face-to-face technique offers the potential for improved accessibility and reduced risk of injury associated with blind scooping maneuvers. In this study, we compared the initial success rate of the face-to-face approach with the conventional method as the primary endpoint and their complications as the second endpoint, including postoperative sore throat, the incidence of bleeding and hoarseness in neckimmobilized patients. Our findings indicate that the initial success rate was 84.1% for the face-to-face approach and 88.6% for the conventional approach (p = 0.381). The intubation times for the face-to-face approach and conventional approach were 12.0 and 14.0 seconds, respectively (p = 0.704). Furthermore, there were no statistically significant inter-group differences observed in the overall incidence of postoperative complications, including sore throat, bleeding and hoarseness. In summary, our study shows that the face-to-face approach in lightwand intubation for neck-immobilized patients could be suggested as one of the alternatives, yielding outcomes similar to the conventional lightwand technique.

The article focuses on congenital laryngeal webs, a rare malformation resulting from embryonic laryngeal recanalization failure, with less than 5 present of congenital laryngeal anomalies. Topics include the anatomical location and etiology of laryngeal webs, presenting symptoms such as hoarseness and respiratory distress, and a case report detailing a 6-year-old with unrecognized laryngeal web misdiagnosed as laryngopharyngeal reflux and vocal cord paresis.

Introduction: Noninvasive respiratory support may be provided to decrease the risk of postextubation failure following surgery. Despite these efforts, approximately 3%–27% of infants and children still experience respiratory failure after tracheal extubation following cardiac surgery. This systematic review evaluates studies comparing the efficacy of high‐flow nasal cannula to conventional oxygen therapy such as nasal cannula and other noninvasive ventilation techniques in preventing postextubation failure in this patient population. Methods: A systematic and comprehensive search was conducted in major databases including MEDLINE, EMBASE, Web of Science, and Central. The search encompassed articles focusing on the prophylactic use of high‐flow nasal cannula following tracheal extubation in pediatric patients undergoing cardiac surgery for congenital heart disease. The inclusion criteria for this review consisted of randomized clinical trials as well as observational, cohort, and case–control studies. Results: A total of 1295 studies were screened and 12 studies met the inclusion criteria. These 12 studies included a total of 1565 children, classified into three groups: seven studies compared high‐flow nasal cannula to noninvasive ventilation techniques, four studies compared high‐flow nasal cannula to conventional oxygen therapy, and one observational single‐arm study explored the use of high‐flow nasal cannula with no control group. There was no significant difference in the incidence of tracheal reintubation between high‐flow nasal cannula and conventional oxygen therapy (risk ratio [RR] = 0.67, 95% confidence interval [CI]: 0.24–1.90, p =.46). However, there was a lower incidence of tracheal reintubation in patients who were extubated to high‐flow nasal cannula versus those extubated to noninvasive ventilation techniques (RR = 0.45, 95% CI: 0.32–0.63, p <.01). The high‐flow nasal cannula group also demonstrated a lower mortality rate compared to the noninvasive ventilation techniques group (RR = 0.31, 95% CI: 0.16–0.61, p <.01) as well as a shorter postoperative length of stay (mean difference = −8.76 days, 95% CI: −13.08 to −4.45, p <.01) and shorter intensive care length of stay (mean difference = −4.63 days, 95% CI: −9.16 to −0.11, p =.04). Conclusion: High‐flow nasal cannula is more effective in reducing the rate of postextubation failure compared to other forms of noninvasive ventilation techniques following surgery for congenital heart disease in pediatric‐aged patients. high‐flow nasal cannula is also associated with lower mortality rates and shorter length of stay. However, when comparing high‐flow nasal cannula to conventional oxygen therapy, the findings were inconclusive primarily due to a limited number of scientific studies available on this specific comparison. Future study is needed to further define the benefit of high‐flow nasal cannula compared to conventional oxygen therapy and various types of noninvasive ventilation techniques.

Objective: Cartilaginous tumors of the larynx are rare, representing less than 1% of all laryngeal tumors. Chondromas are benign mesenchymal tumors characterized by a slow-paced growth, primarily originated in the cricoid cartilage, followed by the thyroid, arytenoid, and epiglottic cartilages. This scoping review aims to understand the extent of evidence on the epidemiology, clinical characteristics, morbidity, and recurrence of the laryngeal chondroma (LC). Data sources: MEDLINE (Ovid), Embase (Elsevier), Web of Science (Clarivate), Cochrane Central Register of Controlled Trials and Systematic Reviews, Lilacs, Scopus, and Google Scholar databases. Review Methods: The scoping review was conducted from 1816 to 2023, for observational studies describing LC. Titles and abstracts were screened for relevance, followed by an evaluation of the full text for eligibility. The data were collected from the qualifying articles, and a narrative summary of the outcomes was prepared. Results: One hundred and nineteen studies met the inclusion criteria. Ninety-four case reports, 22 case series, and 3 cohorts. Two hundred and four participants with a diagnosis of LC were described. Male:female ratio was 2.8:1. The most common localization was the cricoid (113; 47.08%), followed by the thyroid (45; 18.75%), and the arytenoid cartilage (27; 11.25%). Dyspnea (78.85%) and hoarseness (74.28%) were the most reported symptoms. The recurrence rate was 11.25%, and complications were uncommon following the resection. Conclusion: This scoping review found a low-frequency rate over all the cartilaginous laryngeal tumors. Most patients were treated with resection, with a low rate of malignancy conversion. This population has low attributable mortality, morbidity, and recurrence according to the current literature. [ABSTRACT FROM AUTHOR]

Hypothyroidism is a frequently diagnosed endocrine disorder. Common signs and symptoms include fatigue, cold intolerance, hoarseness, dry skin, constipation, a slow relaxation phase of deep tendon reflexes, and bradycardia. However, some patients may exhibit atypical signs and symptoms, which can result in diagnostic confusion. Pituitary hyperplasia resulting from longstanding primary hypothyroidism was first described by Niepce in 1851. It is usually asymptomatic, but sometimes, in addition to symptoms of overt hypothyroidism, patients may complain of headaches, hypopituitarism, visual field impairment, and hyperprolactinemia. Furthermore, on imaging, pituitary hyperplasia can be mistaken for a pituitary adenoma. Distinguishing between the two is crucial, as their management differs; the former often responds to thyroid hormone replacement therapy, while the latter might need treatment with surgery and/or radiotherapy. Here we describe a patient who developed pituitary hyperplasia in the setting of longstanding uncompensated primary hypothyroidism due to a lack of compliance with levothyroxine replacement therapy. We also review the clinical, laboratory, and radiologic findings of the case reports available in the literature up to now in order to improve the knowledge and the care of the disease.

Introduction: Tracheal tumors are rare in the pediatric population. Primary tumors within the trachea often present with non-specific symptoms during the initial stages, leading to a delayed diagnosis. Prompt diagnosis of a tracheal tumor is crucial due to the risk of life-threatening airway obstruction it poses. This article discusses the case of a twelve-year-old girl who experienced 8years of breathing difficulties without an adequate response to treatment. Case Presentation: The patient was referred to Mofid Children's Hospital after experiencing 8 years of difficulty with dyspnea. Her dyspnea was classified as functional class 2 and was accompanied by dry coughs. Additionally, a biphasic stridor was observed during her auscultation. Further investigations revealed an intra-tracheal mass, identified as a mucous gland adenoma (MGA). Imaging and pathology showed no signs of malignancy. Following her surgery, she was completely free of symptoms, and her follow-up spirometry showed no abnormalities. Conclusions: In this article, we present a detailed case of MGA. Despite the low incidence of intra-tracheal tumors, conducting further studies in patients who respond poorly to treatment is crucial. The potential complications from these tumors can be catastrophic. Thus, enhancing our knowledge and expertise in this area is of great importance. [ABSTRACT FROM AUTHOR]

Teachers are at high risk of voice disorders due to the heavy vocal demand of their profession as well as diverse classroom conditions that can stress the voice. Healthy vocal hygiene practices reduce this risk, but many teachers lack knowledge in these areas or have misconceptions about ways to improve their vocal health. This study aimed to identify knowledge deficits among teachers, and directly address topics with poorest performance to better generate vocal health resources for teachers and improve their overall vocal health.

Ortner's syndrome or cardiovocal syndrome is a rare condition referring to laryngeal recurrent nerve paralysis due to cardiovascular conditions. We report the case of a 66-year-old man, with a medical history of active smoking, who complained of hoarseness of voice secondary to vocal cord palsy. A neck and thoracic CT scan revealed severe enlargement of pulmonary main artery, which caused compression of the left recurrent laryngeal nerve in the aortopulmonary window. The prolonged course of the left laryngeal nerve makes it susceptible to injury from cardiovascular structures in the mediastinum. Consequently, cardiovascular conditions such as dilated pulmonary artery or an aneurysm of the aortic arch can compress the nerve, resulting in Ortner's syndrome.
