To examine the frequency and adverse effects of voice disorders on job performance and attendance in teachers and the general population, 2,401 participants from Iowa and Utah (n1 = 1,243 teachers and n2 = 1,279 nonteachers) were randomly selected and were interviewed by telephone using a voice disorder questionnaire. Teachers were significantly more likely(More)
Pediatric patients with voice or speech problems usually should receive a team assessment in which communication between the pediatrician or primary care physician, the otolaryngologist, and speech pathologist occurs. Although speech or voice problems may prompt an otolaryngologic evaluation, the voice or speech problem simply may be the manifestation or(More)
PURPOSE To evaluate a high-resolution, thin-section fast spin-echo MR imaging technique of the inner ear to identify the large vestibular aqueduct syndrome seen on temporal bone CT scans. METHODS We retrospectively reviewed the temporal bone CT scans of 21 patients with hearing loss and enlarged bony vestibular aqueducts by CT criteria. High-resolution(More)
Vocal function was assessed in 15 patients who received thyroplasty type I for the rehabilitation of unilateral vocal fold paralysis. The function was assessed by perceptual evaluation, voice intensity and frequency range profiles, and questionnaire. Goals of the study were to evaluate the efficacy of thyroplasty in improving the voice, to compare(More)
Anchoring fibers are collagenous structures that help secure basal cells to the superficial layer of the lamina propria (SLLP). Transmission electron microscopy was used to study the morphology and organization of these anchoring fibers at the human vocal fold basement membrane zone. This study shows that anchoring fibers loop from the lamina densa through(More)
In humans, vocal tissue stiffness increases with age, suggesting a possible contribution of age-associated variations in vocal fold collagen turnover to voice senescence. The underlying mechanisms remain to be explored. With the use of reverse-transcriptase polymerase chain reaction (RT-PCR), collagen subtypes expressed in rat vocal folds were determined,(More)
