OBJECTIVES/HYPOTHESIS Currently, drug-induced sleep endoscopy (DISE) in obstructive sleep apnea (OSA) is predominantly performed in supine position. When positional therapy (avoidance of supine sleeping position in positional OSA (POSA) is implemented as (part of the) treatment, one should assess levels of obstruction in the other sleeping positions. Therefore, the current study examined the in...

To the Editor:-The McCoy levering laryngoscope is a useful device,’.’ but does not uniformly improve the view in some cases of difficult laryngoscopy.’.’ We report a case in which the McCoy laryngoscope did not improve the direct view of the larynx, but instead lifted the epiglottis and expanded structures around the laryngeal aperture (LA), thereby facilitating “blind” tracheal intubation. A 7...

OBJECTIVE To determine the correlation between anatomical features of the upper airway (evaluated via computed tomography imaging) and the ease of light wand-assisted endotracheal intubation in patients undergoing ear, nose and throat surgery under general anaesthesia. METHODS Mallampati class, laryngoscopic grade, thyromental distance, neck circumference, body mass index, mouth opening and u...

We describe a case of laryngeal amyloidoma in a 39-year-old man in whom CT examination disclosed a calcifield soft-tissue mass arising in the epiglottis. The presence of focal calcifications suggested a cartilaginous tumor.

Nerve growth factor (NGF) exerts its action through two types of receptor: high-affinity tyrosine kinase A receptor (trkA) and low-affinity p75 receptor. NGF has a neurotrophic role in central and peripheral nervous system development, but there is also clear evidence of its involvement in the developing skeleton. The aim of the present immunohistochemical study was to investigate the expressio...

Primary malignant melanoma of the epiglottis is extremely rare. Until now, only 4 cases have been reported in the world literature. We describe a new case of epiglottic primary malignant melanoma in a 74-year-old man who presented with hoarseness and a foreign-body sensation. Clinical examination revealed the presence of a small, whitish, polypoid tumor on the laryngeal surface of the epiglotti...

BACKGROUND The purpose of this study was to show the investigated prevalence rate of brownish spots of early cancer under narrow band imaging (NBI) in different sites/types of the epithelium. METHODS In all, 125 adults with early mucosal cancer underwent NBI examination. Four types of epithelium were categorized: keratinized thick stratified squamous (type 1), nonkeratinized thin (type 2a) or...
