INTRODUCTION Endotracheal intubation in the ICU is a challenging procedure and is frequently associated with life-threatening complications. The aim of this study was to investigate the effect of the C-MAC® video laryngoscope on laryngeal view and intubation success compared with direct laryngoscopy. METHODS In a single-center, prospective, comparative before-after study in an anesthetist-lea...

In this work, we evaluate laryngeal ultrasound as a technique to study the state and height of the larynx. We first discuss general structural registration in laryngeal ultrasound (LUS) and illustrate the articulation of glottal stop. We then present a method for quantifying change in larynx height using optical flow analysis on laryngeal ultrasound video data. The analysis is quantitatively va...

Objective/Hypothesis Comparing detection and extension of malignant tumors by flexible laryngoscopy in the outpatient setting with under general anesthesia using both White Light Imaging (WLI) Narrow Band (NBI). Study Design Prospective study. Methods Two hundred thirty-three patients laryngeal pharyngeal lesions underwent rigid laryngoscopy, WLI NBI. Extension (n = 132) was compared between te...

STUDY OBJECTIVE The objective of this study was to determine the effect of increasing head elevation and neck flexion on the quality of laryngeal view during laryngoscopy. METHODS Laryngoscopy with a straight blade was performed on 7 fresh human cadavers. Laryngeal views were recorded with the direct laryngoscopy video system, and the laryngoscopy angle was measured throughout the procedure w...

OBJECTIVE To evaluate the effect of video laryngoscopy on the rate of endotracheal intubation on first laryngoscopy attempt among critically ill adults. DESIGN A randomized, parallel-group, pragmatic trial of video compared with direct laryngoscopy for 150 adults undergoing endotracheal intubation by Pulmonary and Critical Care Medicine fellows. SETTING Medical ICU in a tertiary, academic m...

Here we present the case of a 64 year old female with a history of neck radiation and Reinke’s edema that experienced unexpected respiratory failure after a sedation anesthetic. After the case terminated, the patient was noted to be hypoventilating and stridorous. Mask ventilation, laryngeal mask airway ventilation, and direct laryngoscopy failed. The patient was intubated with video laryngosco...

IMPORTANCE Vocal fold immobility following injury to the recurrent laryngeal nerve (RLN) may lead to substantial morbidity. A reinnervation treatment strategy offers several theoretical benefits over static treatment options. This study evaluates the robustness of reinnervation of the larynx using a split-hypoglossal nerve graft in an animal model, with outcomes assessed by independent blinded ...

BACKGROUND Exercise-induced laryngeal obstruction (EILO) may affect as many as 6% of the adolescent population, with some patients experiencing symptoms refractory to conservative interventions. OBJECTIVES This report describes therapeutic laryngoscopy during exercise, a novel, non-surgical intervention that harnesses real-time laryngoscopy video as biofeedback to control laryngeal aperture d...
