Effect of intravenous and topical laryngeal lidocaine on sore throat after extubation: a prospective randomized controlled study.

OBJECTIVE: The present study aimed to compare the effect of topical laryngeal lidocaine with intravenous lidocaine before endotracheal intubation on the incidence and severity of postoperative sore throat, hoarseness, and cough. PATIENTS AND METHODS: This prospective randomized controlled study enrolled 144 patients undergoing laparoscopic cholecystectomy with endotracheal intubation. The patients were randomized to three groups and received 2% lidocaine by topical laryngeal spray (group T), intravenous 2% lidocaine (group I), and the equivalent volume of intravenous saline (group C) before intubation. The incidence and severity of sore throat, hoarseness, and cough reaction at 0.5, 1, 6, and 24 h after extubation were collected. RESULTS: The incidence of sore throat was significantly lower in group T than in groups I and C (6.4% vs. 37.2% and 86.7%, p < 0.001), respectively at 0.5 h after extubation, and it was significantly lower in group I than that in group C (37.2% vs. 86.7%, p < 0.001). Both the incidence of hoarseness and cough were significantly lower in group T than in group I and in group C (14.9% vs. 97.7% and 97.8%, p < 0.001, and 19.1% vs. 72.0% and 93.3%, p < 0.001), respectively. The severity of sore throat, hoarseness and cough in group T was significantly lower than that in group I and that in group C (p < 0.05), and it was significantly lower in group I than in group C (p < 0.05). CONCLUSIONS: Both topical laryngeal lidocaine and intravenous lidocaine before intubation have positive effects on preventing sore throat. Topical laryngeal route was superior to intravenous route.

[Thyroid cartilage fracture following sneezing as a cause of spontaneous pneumomediastinum]. / Perelom shchitovidnogo khryashcha vsledstvie chikhan'ya kak prichina spontannogo pnevmomediastinuma.

OBJECTIVE: To evaluate the possible etiological factors of spontaneous pneumomediastinum and to describe a case that was unusual in its etiology: a thyroid cartilage fracture as a result of sneezing. MATERIAL AND METHODS: Six patients (four male, two female, aged 16-82 years) were hospitalized with spontaneous pneumomediastinum diagnosed with a chest X-ray in five patients and 100% with computed tomography. Treatment was symptomatic. RESULTS: The commonest symptoms (cough, shortness of breath, hoarseness) were in four patients. Spontaneous pneumomediastinum developed in three cases as a result of bronchospasm during an attack of bronchial asthma, in one patient after exercise, in one after fibrogastroscopy, in one after sneezing. We report a 30-year-old man who presenting subcutaneous emphysema on the neck, hoarseness, pain when swallowing, hemoptysis developed after sneezing. His computed tomography revealed a pneumomediastinum due to fistula of the fracture of the thyroid cartilage following sneezing while simultaneously obstructing both nostrils. At laryngoscopy, there was a linear hematoma in the resolution stage on the anterior wall of the larynx. He was treated conservatively and recovered rapidly. There are no previous published reports of spontaneous pneumomediastinum following fracture of the thyroid cartilage. CONCLUSION: Fracture of the thyroid cartilage as a result of a sharp rapid increase in airway pressure during a sneeze with blocked nasal passages can be one of the rare causes of spontaneous pneumomediastinum. Avoid closing both nostrils at the same time when sneezing.

A Plasmacytoma of the Lateral Pharyngeal Wall: A Diagnostic Enigma.

Plasmacytoma is a rare plasma cell dyscrasia that grows in bones or soft tissues such as the pharynx. Soft tissue plasmacytomas are rare, and a higher burden has been reported in the upper aero-digestive tract, often manifesting as hoarseness, dysphagia, or odynophagia. Due to their rarity, extramedullary plasmacytomas (EMPs) have unknown prognostic factors, and guidelines for optimal management are still lacking. However, radiation therapy and surgery have been used with positive outcomes. Herein, we describe a unique case of plasmacytoma of the pharyngeal tissue in a male patient with a history of HIV disease. The patient completed 28 sessions of radiation therapy, resulting in an improvement in his throat pain and hoarseness. Given the patient's age and lack of traditional risk factors for head and neck cancers, his hoarseness and odynophagia proved to be a diagnostic conundrum. Although infrequent, soft tissue plasmacytomas should be considered in the differential diagnosis of head and neck tumors.

Extramedullary plasmacytoma of the larynx - Case report.

Extramedullary plasmacytoma of the larynx is an extremely rare entity accounting for 0.04-0.45% of malignant tumours of the larynx. The objective of this clinical case report is to highlight the diagnosis and management of a unique case such as this. A 77-year-old gentleman presented with complaints of hoarseness for 1 year. Computed tomography image revealed a soft tissue mass lesion involving the right true vocal cord. Direct laryngoscopic biopsy was performed and subjected to histopathological examination, which showed collection of plasma cells. Immunohistochemistry confirmed the presence of Kappa and Lambda cells. Multiple myeloma (MM) was ruled out. The patient received radical intent radiation therapy using 3DCRT technique with a dose of 50Gy in 25# over 5 weeks. He experienced improvement in hoarseness on subsequent follow-up visits. At 1-year follow up, positron emission tomography computed tomography showed near total resolution of disease with no progression to MM. Radiation therapy alone is known to achieve good local control, recurrence free survival, and organ preservation in such cases.

The effect of different endotracheal tube cuff pressure monitoring systems on postoperative sore throat in patients undergoing tracheal intubation: a randomized clinical trial.

BACKGROUND: Postoperative sore throat (POST) is an unpleasant outcome that can occur as a result of tracheal intubation in adults. Increased pressure from the endotracheal tube (ETT) cuff often leads to local mucosal injury, resulting in sore throat. The purpose of this study was to compare the effect of two different ETT cuff pressure monitoring systems vs. no cuff pressure monitoring on the incidence and severity of POST in adults. METHODS: One hundred and fourteen ASA I-III patients of either gender, aged 18-65 years, and undergoing surgery requiring endotracheal intubation were included in this study. Patients were randomized into three groups: control (C), cuff pressure gauge (G), and automated cuff controller (A). The ETT cuff pressure was not monitored intraoperatively in group C but was monitored using a cuff pressure gauge and an automated cuff controller in groups G and A, respectively. Postoperatively, patients were assessed at 2, 24, and 48 h for the presence and severity of POST, hoarseness and cough. RESULTS: One hundred and eleven patients completed the study. POST occurred in 40.5% of the patients in group G (n = 37) (p = 0.013) and 23.7% of the patients in group A (n = 38) (p < 0.001) within 48 h after surgery, compared to 69.4% in group C (n = 36). There were no significant differences in hoarseness, coughing, and dysphagia across the groups at any time. When comparing groups A and C, individuals in group A exhibited a lower occurrence of significant (grade ≥ 2) POST and hoarseness (10.5% vs. 41.7%, p = 0.002; 26.3% vs. 58.3%, p = 0.005). The incidence of significant cough and dysphagia did not differ substantially across the patient groups within 48 h after surgery. POST scores in group A at 2, 24 h postoperatively were both 0 (0-0), which was significantly lower than those in group C (1 (0-2) at 2 h, p < 0.001 ; 1 (0-1) at 24 h, p = 0.001). POST in group G at 2 h postoperatively was graded as 0 (0-1.5) which was milder than group C (P = 0.024). The severity of hoarseness in group A with scores of 0 (0-2) was superior to that in group C (2 (0-2), p = 0.006) at 2 h postoperatively. CONCLUSIONS: In conclusion, the findings of this study indicated that the occurrence of POST can be reduced by using either the cuff pressure gauge approach or the automated cuff controller method. The automated cuff controller monitoring can potentially decrease the severity of POST and hoarseness.

The effects of video double-lumen tubes on intubation complications in patients undergoing thoracic surgery: A randomised controlled study.

BACKGROUND: Tracheal injuries, vocal cord injuries, sore throat and hoarseness are common complications of double-lumen tube (DLT) intubation. OBJECTIVE: This study aimed to evaluate the effects of 'video double-lumen tubes' (VDLTs) on intubation complications in patients undergoing thoracic surgery. DESIGN: A randomised controlled study. SETTINGT: Xuzhou Cancer Hospital, Xuzhou, China, from January 2023 to June 2023. PATIENTS: One hundred eighty-two patients undergoing elective thoracic surgery with one-lung ventilation were randomised into two groups: 90 in the DLT group and 92 in the VDLT group. INTERVENTION: VDLT was selected for intubation in the VDLT group, and DLT was selected for intubation in the DLT group. A fibreoptic bronchoscope (FOB) was used to record tracheal and vocal cord injuries. MAIN OUTCOME MEASURES: The primary outcomes were the incidence of moderate-to-severe tracheal injury and the incidence of vocal cord injury. The secondary outcomes included the incidence and severity of postoperative 24 and 48 h sore throat and hoarseness. RESULTS: The incidence of moderate-to-severe tracheal injury was 32/90 (35.6%) in the DLT group, and 45/92 (48.9%) in the VDLT group ( P  = 0.077; relative risk 1.38, 95% CI, 0.97 to 1.95). The incidence of vocal cord injury was 31/90 (34.4%) and 34/92 (37%) in the DLT and VDLT groups, respectively ( P  = 0.449). The incidence of postoperative 24 h sore throat and hoarseness was significantly higher in the VDLT group than in the DLT group (for sore throat: P  = 0.032, relative risk 1.63, 95% CI, 1.03 to 2.57; for hoarseness: P  = 0.018, relative risk 1.48, 95% CI, 1.06 to 2.06). CONCLUSION: There was no statistically significant difference in the incidence of moderate-to-severe tracheal injury and vocal cord injury between DLTs and VDLTs. While improving the first-attempt success rate, intubation with VDLT increased the incidence of postoperative 24 h sore throat and hoarseness.

Ease of endotracheal intubation with the conventional polyvinyl chloride endotracheal tube versus wire-reinforced flexometallic tube through the intubating laryngeal mask airway: A comparative study.

Background The I-LMA ventilates while providing a port for blind insertion of an endotracheal tube. The ILMA Fastrach is used especially for intubating in a difficult airway scenario. Its accompanying endotracheal tube is not economical nor readily available. In comparison, two alternative endotracheal tubes - polyvinyl chloride and wire-reinforced tubes were used for tracheal intubation through the ILMA. AIMS AND OBJECTIVES: The aim of our study was to compare the ease of intubation when using conventional PVC tubes versus the wire-reinforced flexometallic tubes with the ILMA-FastrachTM. The number of attempts, time taken and additional maneuvers were noted. Intra-operative hemodynamic changes, post-operative sore throat, bleeding and hoarseness of voice was recorded over a period of 24 hours. METHODOLOGY: After informed consent, 60 ASA I-II patients undergoing elective surgeries under general anesthesia were allocated to undergo blind intubation with the PVC tube or the wire-reinforced flexometallic tube. RESULTS: More attempts were required for successful intubation using the wire-reinforced tube than the PVC tube with 76.7% passing in the first attempt in the PVC, and 53.3% passing in the first attempt in the flexometallic group. (P = 0.4). Average time for intubation in the PVC group: 28.24 ± 7.22 seconds. Average time for intubation in the flexometallic tube: 45.8 ± 15.78 sec. Occurrence of post-operative sore throat was 13.3% in the PVC group and 26.6% in the flexometallic group, with minimal hoarseness of voice 3.3% in the PVC group and 10% in the flexometallic group. There was also a slightly higher hemodynamic response in those who were intubated with the flexometallic tube than a PVC tube. CONCLUSION: Intubating via the ILMA-Fastrach with the PVC tube offered better intubating conditions with regards to lesser time taken, lesser attempts, less manipulation, and less hemodynamic variations as compared to the patients who were intubated using the wire-reinforced tube.

Résumé Arrière-plan: L'I-LMA ventile tout en fournissant un port pour l'insertion aveugle d'une sonde endotrachéale. L'ILMA Fastrach est utilisé notamment pour l'intubation dans un scénario de voies respiratoires difficiles. La sonde endotrachéale qui l'accompagne n'est ni économique ni facilement disponible. En comparaison, deux tubes endotrachéaux alternatifs ­ du chlorure de polyvinyle et des tubes renforcés de fil ­ ont été utilisés pour l'intubation trachéale via l'ILMA. Buts et objectifs: Le but de notre étude était de comparer la facilité d'intubation lors de l'utilisation de tubes en PVC conventionnels par rapport aux tubes flexométalliques renforcés de fil avec l'ILMA-FastrachTM. Le nombre de tentatives, le temps nécessaire et les manÓuvres supplémentaires ont été notés. Les changements hémodynamiques peropératoires, les maux de gorge postopératoires, les saignements et l'enrouement de la voix ont été enregistrés sur une période de 24 heures. Méthodologie: Après consentement éclairé, 60 patients ASA I-II subissant des interventions chirurgicales électives sous anesthésie générale ont été affectés à une intubation aveugle avec le tube en PVC ou le tube flexométallique renforcé de fil. Résultats: Plus de tentatives ont été nécessaires pour réussir l'intubation à l'aide du tube renforcé par fil métallique qu'avec le tube PVC, avec 76,7 % de réussite lors de la première tentative dans le groupe PVC et 53,3 % de réussite lors de la première tentative dans le groupe flexométallique. (P = 0,4). Temps moyen d'intubation dans le groupe PVC : 28,24 ± 7,22 secondes. Temps moyen d'intubation dans le tube flexométallique : 45,8 ± 15,78 sec. La survenue de maux de gorge postopératoires était de 13,3 % dans le groupe PVC et de 26,6 % dans le groupe flexométallique, avec un enrouement minime de la voix de 3,3 % dans le groupe PVC et de 10 % dans le groupe flexométallique. Il y avait également une réponse hémodynamique légèrement plus élevée chez ceux qui étaient intubés avec le tube flexométallique qu'avec un tube en PVC. Conclusion: L'intubation via l'ILMA-Fastrach avec le tube en PVC offrait de meilleures conditions d'intubation en ce qui concerne moins de temps, moins de tentatives, moins de manipulations et moins de variations hémodynamiques par rapport aux patients intubés à l'aide du tube renforcé de fil Mots-clés: Facilité d'intubation, sonde endotrachéale flexométallique, masque laryngé d'intubation des voies respiratoires, sonde endotrachéale en polychlorure de vinyle.

Comparative Efficacy and Safety of Radiofrequency Ablation and Microwave Ablation in the Treatment of Benign Thyroid Nodules: A Systematic Review and Meta-Analysis.

OBJECTIVE: The current body of evidence lacks clarity regarding the comparative efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) as minimally invasive treatments for benign thyroid nodules. The primary objective of this study is to clarify these concerns. MATERIALS AND METHODS: A comprehensive search was conducted using the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 10th, 2023, using a combination of relevant keywords. This study incorporated literature that compared RFA and MWA for benign thyroid nodules. The primary outcome was the volume reduction ratio (VRR) from baseline to follow-up. Secondary outcomes were symptom score, cosmetic score, ablation time, major complications rate, hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. We used Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool to assess the risk of bias in the included studies. We employed random effects models to analyze the standardized mean difference (SMD) and odds ratio for the presentation of outcomes. RESULTS: Nine studies with 2707 nodules were included. The results of our meta-analysis indicated similar efficacy between RFA and MWA in terms of VRR during the 1 (SMD 0.06; 95% confidence interval [CI]: -0.13 to 0.26; P = 0.52) and 3 (SMD 0.11; 95% CI: -0.03 to 0.25; P = 0.12) months of follow-up. VRR was significantly higher in RFA than in MWA at the 6 (SMD 0.25; 95% CI: 0.06-0.43; P = 0.008) and 12 month of follow-up (SMD 0.38; 95% CI: 0.17 to 0.59; P < 0.001). There were no significant differences between RFA and MWA in symptom scores, cosmetic scores, or the incidence of complications, including hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. CONCLUSION: RFA showed a higher VRR than MWA at 6 and 12-month follow-ups, with a comparable safety profile.

Squamous Cell Carcinoma of the Supraglottis Presenting as Hoarseness.

Hoarseness is a well-known condition in primary care offices, with over 1% of primary care visits secondary to this ailment.1 The most common causes are acute laryngitis (40%), functional dysphonia (30%), benign and malignant tumors (2.2 to 30%), neurogenic factors such as vocal cord paralysis (8%), physiological aging (2%), and psychogenic factors (2.2%). Most of these cases are secondary to viral infections and do not require antibiotics on most occasions. These viral infections subside after 1 to 2 weeks, and in the case of persistent hoarseness (above 4 weeks) the American Academy of Otolaryngology recommends direct visualization with a laryngoscopy before treatment with proton pump inhibitors, antibiotics, or steroids. Our patient presented with prolonged hoarseness (greater than eight weeks) but had a quick turn around time interval between primary care visit and laryngoscopy evaluation (less than 2 weeks). This led to her diagnosis and treatment with chemo and radiation therapy within three months of diagnosis with Squamous Cell Carcinoma of the Supraglottis. The Primary care physician serves as the number one point of visitation by sufferers of hoarseness. It is important that they are knowledgeable and up to date with recommendations and guidelines for managing this condition, as unwarranted delay can affect overall outcome on the part of the patient. This is especially important in patients such as ours with high risk factors including Nicotine dependence, alcohol use, asbestos exposure, and HPV infection.

La voix rauque est une condition bien connue dans les cabinets de soins primaires, avec plus de 1 % des visites en soins primaires dues à ce problème. Les causes les plus courantes sont la laryngite aiguë (40%), la dysphonie fonctionnelle (30 %), les tumeurs bénignes et malignes (2,2 à 30 %), les facteurs neurogènes tels que la paralysie des cordes vocales (8 %), le vieillissement physiologique (2 %) et les facteurs psychogènes (2,2 %). La plupart de ces cas sont dus à des infections virales et ne nécessitent pas d'antibiotiques dans la plupart des cas. Ces infections virales disparaissent après 1 à 2 semaines, et en cas de voix rauque persistante (plus de 4 semaines), l'American Academy of Otolaryngology recommande une visualisation directe avec une laryngoscopie avant le traitement par inhibiteurs de la pompe à protons, antibiotiques ou stéroïdes. Notre patiente présentait une voix rauque prolongée (plus de huit semaines), mais a bénéficié d'un délai rapide entre la visite en soins primaires et l'évaluation par laryngoscopie (moins de 2 semaines). Cela a conduit à son diagnostic et à son traitement par chimiothérapie et radiothérapie dans les trois mois suivant le diagnostic de carcinome épidermoïde du supraglotte. Le médecin de soins primaires est le premier point de visite pour les personnes souffrant de voix rauque. Il est important qu'ils soient informés et à jour des recommandations et des lignes directrices pour la prise en charge de cette condition, car un retard non justifié peut affecter le résultat global pour le patient. Ceci est particulièrement important chez les patients comme le nôtre présentant des facteurs de risque élevés, y compris la dépendance à la nicotine, la consommation d'alcool, l'exposition à l'amiante.

The effectiveness of various treatment approaches for laryngeal contact granulomas.

OBJECTIVES: To assess and compare the effectiveness of various treatment approaches for laryngeal contact granulomas (LCG). METHODS: A retrospective analysis was conducted on a cohort of 45 patients diagnosed with LCG at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2017 to May 2023. Based on the treatment modalities administered, patients were categorized into three groups: acid suppression alone, hormone injection combined with acid suppression, and surgery combined with acid suppression. Subsequently, the study compared differences in treatment efficacy and average healing time among these three groups, using various indicators. RESULTS: The findings indicate that the granuloma size in LCG patients with hoarseness (0.126, 95% CI 0.087-0.288) was significantly greater compared to LCG patients without hoarseness (0.047, 95% CI 0.014-0.083) (P = 0.001). However, there were no significant variations in age, morphology (unlobulated/lobulated), laterality ratio (left/right), sex ratio (male/female), history of tracheal intubation (non-intubation/intubation), and RFS score (RFS > 7/RFS ≤ 7) (P > 0.05), regardless of the presence of hoarseness symptoms. At the treatment observation endpoint of 3 months, the curative ratio in the group receiving hormone injection combined with acid suppression was found to be significantly higher compared to the group receiving acid suppression alone (P = 0.018). In addition, the average healing time of patients in the hormone injection combined with acid suppression group was notably shorter than that of the acid suppression alone group (P = 0.007). CONCLUSIONS: The combination of hormonal injections and acid suppression may enhance the curative ratio and expedite the healing time of LCG.

Machine learning based estimation of hoarseness severity using sustained vowelsa).

Auditory perceptual evaluation is considered the gold standard for assessing voice quality, but its reliability is limited due to inter-rater variability and coarse rating scales. This study investigates a continuous, objective approach to evaluate hoarseness severity combining machine learning (ML) and sustained phonation. For this purpose, 635 acoustic recordings of the sustained vowel /a/ and subjective ratings based on the roughness, breathiness, and hoarseness scale were collected from 595 subjects. A total of 50 temporal, spectral, and cepstral features were extracted from each recording and used to identify suitable ML algorithms. Using variance and correlation analysis followed by backward elimination, a subset of relevant features was selected. Recordings were classified into two levels of hoarseness, H<2 and H≥2, yielding a continuous probability score y∈[0,1]. An accuracy of 0.867 and a correlation of 0.805 between the model's predictions and subjective ratings was obtained using only five acoustic features and logistic regression (LR). Further examination of recordings pre- and post-treatment revealed high qualitative agreement with the change in subjectively determined hoarseness levels. Quantitatively, a moderate correlation of 0.567 was obtained. This quantitative approach to hoarseness severity estimation shows promising results and potential for improving the assessment of voice quality.

Comparative study of left vertebral artery revascularization in patients with and without aberrant left vertebral anatomy.

OBJECTIVE: Left vertebral artery revascularization is indicated in surgery involving zone 2 of the aortic arch and is typically accomplished indirectly via subclavian artery revascularization. For aberrant left vertebral anatomy, direct revascularization is indicated. Our objective was to compare the outcomes of direct vertebral artery revascularization with indirect subclavian artery revascularization for treating aortic arch pathology and to identify predictors of mortality. METHODS: A retrospective cohort study was conducted at a single tertiary hospital, including patients who underwent open or endovascular vertebral artery revascularization from 2005 to 2022. Those who underwent direct vertebral revascularization were compared with those who were indirectly revascularized via subclavian artery revascularization. The outcomes of interest were a composite outcome (any of death, stroke, nerve injury, and thrombosis) and mortality. Univariate logistic regression models were fitted to quantify the strength of differences between the direct and indirect revascularization cohorts. Cox regression was used to identify mortality predictors. RESULTS: Of 143 patients who underwent vertebral artery revascularization, 21 (14.7%) had a vertebral artery originating from the aortic arch. The median length of stay was 10 days (interquartile range, 6-20 days), and demographics were similar between cohorts. The incidence of composite outcome, bypass thrombosis, and hoarseness was significantly higher in the direct group (42.9% vs 18.0%, P = .019; 33.3% vs 0.8%, P < .0001; 57.1% vs 18.0%, P < .001, respectively). The direct group was approximately three times more likely to experience the composite outcome (odds ratio, 3.41; 95% confidence interval, 1.28, 9.08); similarly, this group was approximately six times more likely to have hoarseness (odds ratio, 5.88; 95% confidence interval, 2.21, 15.62). There was no significant difference in mortality rates at 30 days, 1, 3, 5, and 10 years of follow-up. Age, length of hospital stay, and congestive heart failure were identified as predictors of higher mortality. After adjusting for these covariates, the group itself was not an independent predictor of mortality. CONCLUSIONS: Direct vertebral revascularization was associated with higher rates of composite outcome (death, stroke, nerve injury, and thrombosis), bypass thrombosis and hoarseness. Patients with aberrant vertebral anatomy are at higher risks of these complications compared with patients with standard arch anatomy. However, after adjusting for other factors, mortality rates were not significantly different between the groups.

Laryngological Complaint Prevalence in Hypermobile Ehlers-Danlos or Hypermobility Spectrum Disorders.

OBJECTIVE: The aim was to study laryngological complaints in patients with hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobility spectrum disorders (HSD). METHODS: A total of 363 patients met inclusion for the study by completing questions related to voice, upper airway, and swallowing between July 7, 2020 and July 13, 2022. Demographic data, voice-related questions, and hypermobility diagnosis were analyzed retrospectively. From those, 289 patients were diagnosed with hEDS or HSD with 74 that did not meet the diagnostic criteria for either diagnosis serving as controls. RESULTS: There were no statistically significant differences between patients with hEDS and HSD regarding Voice Handicap Index (VHI-10) scores, voice, upper airway, or swallow complaints. However, more hEDS/HSD patients answered positively to the laryngeal dysfunction question versus controls (p = 0.031). 22.5% of hEDS/HSD patients (n = 65) reported hoarseness, of which 52.3% reported hoarseness >2 days/month. 33.9% (n = 98) with hEDS/HSD reported symptoms of dysphagia, and 27.0% (n = 78) reported laryngeal dysfunction symptoms. Controls demonstrated 20.3% prevalence of hoarseness, of which 46.7% reported hoarseness >2 days/month. 24.3% of controls had dysphagia and 14.9% laryngeal dysfunction symptoms. Of the 363 patients, VHI-10 scores >11 were more likely in patients reporting >2 days of hoarseness/month (p = 0.001) versus those with <2 days of hoarseness/month. There was an increased prevalence of voice, upper airway, and dysphagia symptoms in hEDS/HSD patients compared with previously reported prevalence data in the general population. CONCLUSION: A significant proportion of patients diagnosed with hypermobility due to hEDS or HSD were found to have voice, upper airway, and dysphagia symptoms. These rates are higher than those previously reported in the general population. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:773-778, 2024.

An Atypical Cause of Hoarseness in a Patient With Thyroid Nodules.

Hoarseness due to vocal fold paresis (VFP) has a multitude of etiologies including systemic lupus erythematosus (SLE). During a clinical evaluation of a 58-year-old woman with long-standing hoarseness, an incidental finding of thyroid nodules was found to have VFP. Direct laryngoscopy and vocal fold biopsy confirmed the source was an inflammatory process involving the cricoarytenoid joint of the right hemilarynx. A presumptive diagnosis of SLE was made 3 years before meeting the clinical criteria of overt SLE. The VFP debut of SLE is extremely rare, and a literature review includes a handful of case reports (4 of a total of 37) since 1959. Only partial recovery of laryngeal function using glucocorticoids and Plaquenil was accomplished in the current case.

Clinical characteristics and prognosis of laryngeal tuberculosis combined with respiratory tuberculosis.

PURPOSE: To investigate the clinical characteristics, diagnosis and prognosis of patients with laryngeal tuberculosis (LTB) combined with respiratory tuberculosis. MATERIALS AND METHODS: A retrospective analysis was conducted on 134 patients who underwent endoscopy and were eventually diagnosed with LTB. The patients' demographic characteristics, clinical manifestations, endoscopic features, auxiliary examination, imaging examination and prognostic characteristics were analyzed. RESULTS: LTB patients had a median age of 45.5 years (range from 12 to 87 years) and a median course of 3.0 months (range from 0.1 to 72 months). The patients' symptoms mainly presented as hoarseness (97.0 %), abnormal sensation of pharyngeal (49.3 %), cough and sputum (41.0 %), pharyngalgia (39.6 %), dysphagia (10.4 %) and dyspnea (8.2 %). The positive rate of tuberculous symptoms was 25.4 %. Endoscopic features showed that the lesions mainly involved the glottis (87.3 %), presenting as unilateral lesions (66.7 %), near-full-length involvement (88.0 %), with mucosal waves significantly reduced (86.3 %), followed by supraglottis (43.3 %), subglottis (24.6 %) and the pharynx (15.7 %). The lesions may present as granulomatous proliferation (66.4 %), ulceration (65.7 %) or swelling and exudation (51.5 %). A total of 75 patients (56.0 %) were finally diagnosed with combined pulmonary tuberculosis (PTB), with a positive chest X-ray rate of 25.6 % and a positive chest CT rate of 71.2 %. A total of 42 patients who received anti-tuberculosis treatment were followed up, and 73.8 % of patients had significant improvement in symptoms. The morphology of the pharyngeal and laryngeal mucosa returned to basically normal (59.4 %) or scar-like (34.4 %). CONCLUSIONS: LTB is usually found in middle-aged men, and patients' symptoms are mainly hoarseness, abnormal sensation of pharyngeal, pharyngalgia, cough and sputum, and can be combined with tuberculous symptoms. These lesions mainly involve multiple subregions, mainly in the glottis, and can be combined with pharyngeal involvement. There were various types of lesions. Half of the patients were complicated with PTB, and chest CT was superior to X-ray in the detection of pulmonary lesions. After regular anti-tuberculosis treatment, the symptoms and morphology of the pharyngeal and laryngeal mucosa of most patients were significantly improved.

Effect of thermal softening of double-lumen endobronchial tubes on postoperative sore throat in patients with prior SARS-CoV-2 infection: a randomized controlled trial.

BACKGROUND: The incidence of postoperative sore throat (POST) after tracheal intubation using double-lumen endobronchial tubes (DLTs) is higher in patients with prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than in the general population. This prospective trial was conducted to determine whether thermal softening of DLTs could decrease the incidence of POST or other airway injuries in patients with prior SARS-CoV-2 infection. METHODS: A total of 120 patients with prior SARS-CoV-2 infection undergoing thoracoscopic surgery were randomly assigned to two groups (n = 60 each). In the thermal softening group, the distal portion of the DLT was placed in thermostatic saline (50 °C) for 10 min before endotracheal intubation. In the control group, the distal portion of the DLT was placed in room temperature saline for 10 min before endotracheal intubation. The incidence and severity of POST and hoarseness were assessed at 1, 6 and 24 h postoperatively. The primary outcomes were the incidence and severity of POST at 6 h postoperatively. The secondary outcomes were the incidence and severity of hoarseness, vocal cord and tracheal injuries, and hemodynamic changes in patients at intubation. RESULTS: The incidence of POST at 6 h postoperatively was greater in the control group than in the thermal softening group [41 (68%) vs. 22 (37%), P = 0.001]. The overall incidence of POST at 24 h postoperatively was greater in the control group than in the thermal softening group [46 (76%) vs. 24 (40%), P < 0.001]. The overall incidence of tracheal injuries was also greater in the control group than in the thermal softening group (P = 0.016). Vocal cord injuries occurred more frequently in the control group than in the thermal softening group (P = 0.006). CONCLUSION: Thermal softening of DLTs before intubation can reduce the incidence of POST and airway injuries in patients with prior SARS-CoV-2 infection undergoing DLT insertion.

Malignant Minor Salivary gland neoplasms ofLarynx: Our Experience.

<br><b>Introduction:</b> Malignant minor salivary gland tumors are rare, accounting for fewer than 1% of all laryngeal cancers.</br> <br><b>Aim:</b> This study aims to share our experiences regarding clinical, radiological, pathological profiles and their management.</br> <br><b>Materials and methods:</b> The current study reviews 11 cases of malignant minor salivary gland tumors of the larynx treated surgically at our Institute between 2005 and 2019.</br> <br><b>Results:</b> The mean age of the patients was 54 years (range 38-75 years) with six females and five males in the series (1.2:1). Subglottis and trachea were the sites of origin in 54% of the cases, and hoarseness with dyspnea were the most common presenting symptoms. There were nine Adenoid cystic and two Mucoepidermoid carcinoma patients. Surgery was the primary mode of treatment.</br> <br><b>Conclusions:</b> Most of the larynx's malignant minor salivary gland tumors are submucosal in origin. The outcome and prognosis vary considerably based on the tumor's histology, grade, and stage.</br>.
