Phonation critically depends on precise controls of laryngeal muscles in coordination with ongoing respiration. However, the neural mechanisms governing these processes remain unclear. We identified excitatory vocalization-specific laryngeal premotor neurons located in the retroambiguus nucleus (RAmVOC ) in adult mice as being both necessary and sufficient for driving vocal cord closure and eliciting mouse ultrasonic vocalizations (USVs). The duration of RAmVOC activation can determine the lengths of both USV syllables and concurrent expiration periods, with the impact of RAmVOC activation depending on respiration phases...

The primary objective of the study was to find out the aetiology of hoarseness and analyse people with hoarseness based on socio-demographic profile like age, gender, occupation and socio-economic status. Secondary objective was to find out the predisposing factors of hoarseness and to see their association between benign and malignant causes of hoarseness. The study was conducted for a period of one and half years in 178 patients who were above the age of 18 years of age and presented with hoarseness lasting for more than 2 weeks to the Department of Otorhinolaryngology...

BACKGROUND: Intravascular papillary endothelial hyperplasia (IPEH) also known as Masson's tumour named after Pierre Masson is a benign lesion of vascular origin which is characterized by reactive proliferation of endothelial cells with papillary formation. It is an extremely rare entity which can present anywhere in the body but is particularly found in the extremities and head and neck regions most commonly the lips, oral mucosa, tongue, gingiva, or buccal mucosa and due to its close resemblance to Angiosarcoma, it becomes important to distinguish between these two entities to avoid unnecessary aggressive treatment...

Purpose Leukoplakia is a macroscopic morphological term for thick white or grey mucosal patches that can represent various histologic diagnostic entities ranging from hyperplasia to malignancy. Aim was the study morphology of the superficial mucosa and microvascular network of the vocal cords in patients with suspected glottic squamous cell carcinoma (SCC) using contact endoscopy (CE). Material and Methods Seventy-nine patients (21 female, 58 male), with a mean age of 57.5 years ± 7.12 (range, 32-73 years), were prospectively enrolled and evaluated...

PURPOSE: Recurrent laryngeal nerve injury after thyroid surgery may cause vocal cord palsy (VCP), which leads to unexpected additional costs. In recent years, intraoperative neural monitoring (IONM) has been used to lower the incidence rate of VCP. This study aimed to analyze postoperative management costs for patients with papillary thyroid carcinoma (PTC). METHODS: We analyzed the medical records of patients who underwent lobectomy for PTC from September 2018 to August 2019 at The Catholic University of Korea, Seoul St...

Ortner's syndrome, a rare condition characterized by hoarseness due to left recurrent laryngeal nerve palsy caused by cardiovascular structural compression, is typically associated with an enlarged left atrium secondary to conditions like mitral stenosis. However, recent studies propose additional causes, including compression between the dilated pulmonary artery and the aorta. We present a case of a 54-year-old male with Ortner's syndrome secondary to severe mitral regurgitation and pulmonary hypertension...

PURPOSE: Ultrasound performed after extubation has been suggested to be useful for the diagnosis of recurrent laryngeal nerve (RLN) paralysis. However, the use of ultrasound for this purpose before extubation has not been examined. The aim of this study was to examine the versatility (interrater reliability) and usefulness of ultrasound for evaluating the movement of vocal cords before extubation.

This observational study aimed to compare the glottic view between video and direct laryngoscopy for tracheal intubation in the surgical position for thyroid surgery with intraoperative neuromonitoring. Patients scheduled for elective thyroid surgery with intraoperative neuromonitoring were enrolled. After the induction of anesthesia, patients were positioned in the thyroid surgical posture with a standard inclined pillow under their head and back. An investigator assessed the glottic view using the percentage of glottic opening (POGO) scale and the modified Cormack-Lehane grade in direct laryngoscopy and then video laryngoscopy sequentially while using the same McGRATH™ MAC video laryngoscope at once, with or without external laryngeal manipulation, at the surgical position...

BACKGROUND: Laryngopharyngeal reflux (LPR) refers to the backflow of acidic stomach content into the larynx, pharynx, and upper aerodigestive tract. The diagnosis of LPR is based on the patient's history and findings of the laryngoscopy associated with LPR. Other possible manifestations consistent with LPR symptoms include laryngeal cancer, vocal fold granulomas, Reinke's space edema, and vocal polyps. In this study, we compared the characteristics of patients with LPR symptoms and incidental laryngeal findings (ILF) in the laryngoscopic evaluation to those without ILF (WILF)...

BACKGRUOUND: Active surveillance (AS) has been introduced as a management strategy for low-risk papillary thyroid carcinoma (PTC) due to its typically indolent nature. Despite this, the widespread adoption of AS has encountered several challenges. The aim of this systematic review was to evaluate the safety of AS related to disease progression and its benefits compared with immediate surgery (IS). METHODS: Studies related to AS in patients with low-risk PTC were searched through the Ovid MEDLINE, Embase, Cochrane Library, and KoreaMed databases...

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...

Hereditary neuropathy with liability to pressure palsy (HNPP) is a rare peripheral neurological disorder that manifests with increased sensitivity to pressure. In people with this disorder, the peripheral nerves are unusually sensitive to pressure. Minor trauma or compression causing paralysis in the extremities is a hallmark of this disorder. Ensuring there is no pressure on the extremities is recommended as a preventive measure. We describe for the first time, postoperative vocal cord paralysis in a patient with HNPP due to left recurrent laryngeal nerve palsy...

Foreign body (FB) inhalation in the pediatric population is a common emergency referral in otolaryngology practice. Mismanagement can lead to significant morbidity or even mortality. Anesthesiologists conventionally use the Cook® airway exchange catheter (CAEC) during endotracheal tube exchange in the intensive care unit, but its usage as an oxygen conduit is beneficial in other airway procedures. A healthy two-year-old boy was brought to casualty for allegedly choking on a boneless chicken meat bolus during mealtime...

Parkinson's disease patients have early vocal cord damage, and their voiceprint characteristics differ significantly from those of healthy individuals, which can be used to identify Parkinson's disease. However, the samples of the voiceprint dataset of Parkinson's disease patients are insufficient, so this paper proposes a double self-attention deep convolutional generative adversarial network model for sample enhancement to generate high-resolution spectrograms, based on which deep learning is used to recognize Parkinson's disease...

This report details a challenging case of difficult extubation due to a lodged tracheal tube following surgery, presenting an unexpected and complex clinical situation. An inspection of the airway using videolaryngoscopy revealed an over-inflated cuff beneath the vocal cords. Initial efforts to deflate the cuff with various methods were unsuccessful. The situation was ultimately resolved through the intervention of an otolaryngology surgeon. This case not only reviews various mechanisms of difficult endotracheal tube removal reported in the literature, but also underscores the potential for serious complications and highlights the critical role of multidisciplinary collaboration in managing extubation challenges...
