OBJECTIVES/HYPOTHESIS Despite the high prevalence of voice disorders, the prevalence of laryngeal disease in the general population has not been determined using laryngoscopy. Factors considered associated with laryngeal disease have mostly been assessed using patient data or highly specific populations. We evaluated the prevalence of and associated factors with laryngeal diseases in the genera...

Objective: The aim of this study was to compare the success rates for insertion using the laryngeal mask, laryngeal tube, and I-gel supraglottic airway devices in a neonatal airway manikin during a resuscitation simulation course. Methods: Three groups of health care professionals were given a brief supervised training in using the devices. For each participant the positioning of each device wa...

Recurrent laryngeal nerve palsy is a common post-operative complication of many head and neck surgeries. Theoretically, the best treatment to restore partial function to a damaged recurrent laryngeal nerve would be reinnervation of the posterior cricoarytenoid muscle via anastomosis of the recurrent laryngeal and phrenic nerves. The pig is an excellent model of human laryngeal anatomy and physi...

OBJECTIVE To investigate the protein expression of matrix metalloproteinase 2 (MMP2) and its clinical significance in laryngeal cancer. METHODS A comprehensive search for the related literature published in China and other countries was conducted in a variety of databases, including MEDLINE, Embase, China Academic Journals Full-text Database, Wanfang Data and VIP Database. A total of seven ca...

BACKGROUND AND PURPOSE The larynx is a rare site for primary NHL. Fewer than 100 cases have been reported in the literature, with the largest imaging review involving only 4 patients. We describe the findings of laryngeal lymphoma on CT, PET, and MR imaging and identify features that may distinguish laryngeal lymphoma from the far more common laryngeal squamous cell carcinoma. MATERIALS AND M...

OBJECTIVE Laryngeal hemiplegia, also known as vocal fold paralysis, causes severe communicative disability. Although voice therapy is commonly considered to be beneficial for improving the voice quality in several voice disorders, there are only a few papers that present scientific evidence of the effectiveness of voice therapy in treating the disabilities of laryngeal hemiplegia. The aim of th...

Introduction The outcome of thyroid surgery is usually assessed according to two major complications: recurrent laryngeal nerve paralysis and hypoparathyroidism. The purpose of the study was to monitor the outcomes of thyroid surgery using Shewhart control charts, and then to identify possible ways to improve quality by exploring the special causes of variation in the observed complication rate...

Laryngeal papillomas are benign tumors caused by human papillomaviruses types 6 and 11. This study addressed alterations in levels of signal transduction from the epidermal growth factor receptor (EGFR) in papillomas and cultured papilloma cells compared to normal tissue and cells. Mitogen-activated protein kinase (MAPK) was activated to a greater extent, phosphotyrosine was more abundant, and ...

Speech production is one of the most complex and rapid motor behaviors, and it involves a precise coordination of more than 100 laryngeal, orofacial, and respiratory muscles. Yet we lack a complete understanding of laryngeal motor cortical control during production of speech and other voluntary laryngeal behaviors. In recent years, a number of studies have confirmed the laryngeal motor cortical...
