PURPOSE OF REVIEW To summarize recent technological advancements and insight into the role of stroboscopy in laryngeal imaging. RECENT FINDINGS Although stroboscopic technology has not undergone major technological improvements, recent clarifications have been made to the application of stroboscopic principles to video-based laryngeal imaging. Also recent advances in coupling stroboscopy with...

Abstract Introduction Drug-induced sleep endoscopy (DISE) is a useful tool for assessing upper airway collapse in patients with obstructive apnea (OSA) and frequently influences surgical plans. The standard DISE setup of an endoscopic tower flexible bronchoscope adequate visualizing configurations, but findings do not always correlate actual respiratory physiology. We describe our enhanced clin...

OBJECTIVE To determine the role played by the tensor veli palatini and levator veli palatini muscles (mTVP and mLVP, respectively) in eustachian tube (ET) opening. DESIGN Prospective study. SETTING Research laboratories at a tertiary care hospital. PATIENTS Fifteen healthy adults with normal middle ears and documented ET openings. INTERVENTIONS Submental and ground surface electrodes we...

The equine upper airway is highly adapted to provide the extremely high oxygen demand associated with strenuous aerobic exercise in this species. The tongue musculature, innervated by the hypoglossal nerve, plays an important role in airway stability in humans who also have a highly adapted upper airway to allow speech. The role of the hypoglossal nerve in stabilizing the equine upper airway ha...

The aim of this study was to determine whether the lung side being sampled would significantly influence bronchoalveolar lavage (BAL) cytological profiles and subsequent diagnosis in Standardbred racehorses. One hundred and thirty-eight French Trotters in active training and racing were included in a prospective observational study. BAL was performed using videoendoscopy in both right and left ...

OBJECTIVE To compare upper airway mechanics, arterial blood gases, and tracheal contamination in horses with induced left laryngeal hemiplegia (recurrent laryngeal neuropathy [RLN]) treated by laryngoplasty/vocal cordectomy (LPVC) or modified partial arytenoidectomy (MPA). STUDY DESIGN Repeated measures under the following conditions: Control, RLN, LPVC, and MPA. ANIMALS Six horses. METHO...

BACKGROUND Laser assisted uvulopalatoplasty (LAUP) is increasingly offered for the treatment of obstructive sleep apnoea (OSA), although there is a lack of objective data to support its indications and efficacy. A study was undertaken to determine the treatment response to LAUP. METHODS Overnight polysomnography was performed before and at least three months after surgery in 44 consecutive pa...

OBJECTIVE In the present study, an attempt was made to examine the effects of aural stimulation with ointment containing capsaicin on swallowing function in order to develop a novel and safe treatment for non-obstructive dysphagia in elderly patients. DESIGN A prospective pilot, non-blinded, non-controlled study with case series evaluating a new treatment. SETTING Secondary hospitals. PAT...

OBJECTIVES/HYPOTHESIS To seek a correlation between the four types of transoral supraglottic laryngectomies (TSLs) according to the European Laryngological Society (ELS) and postoperative morbidity. STUDY DESIGN Retrospective case series at an academic institution. METHODS Chart review was done for 96 patients affected by T1-T3 supraglottic cancers (28 pT1, 46 pT2, 22 pT3) treated by TSL (2...

BACKGROUND AND PURPOSE A close correlation between B-mode sonography and the histopathology and surface structure of plaque is rarely seen in vivo with high-grade stenoses of the extracranial carotid artery. The goal of this study was to determine whether normalized gray scale analysis and surface analysis of the plaque are capable of characterizing the attributes correctly. METHODS Optimized...
