Continuous laryngoscopy quantitates laryngeal behaviour in exercise and recovery

Continuous laryngoscopy quantitates laryngeal behaviour in exercise and recovery.

Exercise-induced laryngeal obstruction (E-ILO) causes exertional dyspnoea. There is no standardised methodology which characterises laryngeal obstruction in relation to exercise or links laryngeal obstruction and dyspnoea severity. Continuous laryngoscopy during exercise (CLE) may improve diagnostic sensitivity by enabling laryngeal visualisation at peak work capacity in patients with rapidly r...

Assessment of effect of nasal continuous positive pressure on laryngeal opening using fibre optic laryngoscopy.

AIM To assess the effect of nasal continuous positive airways pressure (CPAP) on the dimensions of the laryngeal opening. METHODS Nine preterm infants who had previously received ventilatory support for respiratory distress syndrome (RDS) were studied. All were receiving nasal CPAP. The laryngeal opening was visualised using a fibre optic video camera system. The ratio of width to length of t...

Voice Recovery in a Patient with Inhaled Laryngeal Burns

Introduction: Laryngeal burns cause long-term voice disorders due to mucosal changes of the vocal folds. Inhalation injuries affect voice production and result in changes in the mucosal thickness and voice quality.   Case Report: A 47-year-old woman was transferred to our department with laryngeal burns sustained during a house fire. On laryngoscopic examination, mucosal waves of both vocal fol...

A study of laryngeal gestures in Mandarin citation tones using simultaneous laryngoscopy and laryngeal ultrasound (SLLUS)

Head-elevated laryngoscopy position: improving laryngeal exposure during laryngoscopy by increasing head elevation.

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...
