Rationale and Objectives. The purpose of this retrospective study was to estimate the economic consequences of evaluating suspected vocal cord paralysis with magnetic resonance (MR) imaging and computed tomography (CT). Materials and Methods. Reports from MR imaging (n = 30) or CT (n = 19) studies of the neck in 49 patients were retrospectively reviewed for causes of vocal cord paralysis. The p...

Sleep related respiratory dysfunction and vocal cord paralysis are considered to be the major factors responsible for respiratory failure in multiple system atrophy (MSA). We report a patient initially presenting with alveolar hypoventilation culminating in respiratory failure, ultimately diagnosed as MSA. No central sleep apnea or marked paralysis of the vocal cords was noted. The most likely ...

The purpose of this study was to evaluate the effectiveness of several acoustic measures in predicting breathiness ratings. Recordings were made of eight normal men and seven normal women producing normally phonated, moderately breathy, and very breathy sustained vowels. Twenty listeners rated the degree of breathiness using a direct magnitude estimation procedure. Acoustic measures were made o...

The degree of glottal closure during phonation has an influence on voice quality and it is related to the robustness of the voice source. To quantify glottal closure a frame of reference was created by investigating 47 healthy men and 92 healthy women with no vocal complaints using videolaryngostroboscopy. Observing recorded images the degree of glottal closure was rated with a percentage. Resu...

CASE PRESENTATION A non-smoking 45-year-old white man presented with a globus sensation worsened by lying down, with no complaints of hoarseness or dysphonia. He denied fever, fatigue, cough, chest pain, sweats, weight loss, reflux, arthralgias, myalgias and rash. He also denied exposure to asbestosis, beryllium, silica, HIV or tuberculosis, but he reported a recent cat bite. Physical examinati...
