OBJECTIVES/HYPOTHESIS This study intends to objectively quantify and compare the regression rates of vocal lesions in patients receiving either vocal fold steroid injection (VFSI) or vocal hygiene education (VHE). Potential influence of occupational vocal demands on the treatment outcome was also investigated. STUDY DESIGN Retrospective case series. METHODS This study enrolled 176 patients ...

background:speech is the most important communication tool and is the smooth product of four systems: respiratory, phonatory, resonatory, and articulatory. currently, a variety of voice disorder occurred because of life style and environmental pollutants. vocal nodule is one of the most prevalent disorders in this category. considering the point that the air required for vocal cords vibration i...

OBJECTIVES This case-control designed field study examines the vocal behavior in teachers with self-estimated voice problems (VP) and their age- and school-matched voice healthy (VH) colleagues. It was hypothesized that teachers with and teachers without VP use their voices differently regarding fundamental frequency, sound pressure level (SPL), and in relation to the background noise. METHOD...

Budgerigars were trained to produce specific vocalizations (calls) using operant conditioning and food reinforcement. The bird's call was compared to a digital representation of the call stored in a computer to determine a match. Once birds were responding at a high level of precision, we measured the effect of several manipulations upon the accuracy and the intensity of call production. Also, ...

Using long-term-spectrum (LTAS) analysis of fluent speech, the effects of speaking in noise and of speaking with differently filtered auditory feedback as well as of voluntarily changing vocal intensity are analyzed in nine male adult singers and nonsingers. Three values in the LTAS are analyzed: the level of the main pedk near 500 HZ, of a secondary peak near 2000 Hz and at the average fundame...

OBJECTIVES/HYPOTHESIS Unilateral vocal fold paralysis with no preceding causes is diagnosed as idiopathic unilateral vocal fold paralysis. However, comprehensive guidelines for evaluating the defining characteristics of idiopathic unilateral vocal fold paralysis are still lacking. In the present study, we hypothesized that idiopathic unilateral vocal fold paralysis may have different clinical a...

case presentation herein, we reported a case of a 22-year-old woman diagnosed with erms, t1n0m0 stage, localized at the right vocal cord. tumor was successfully treated with a radical excision and selective neck dissection and followed-up for 5 years with no evidence of local recurrence. introduction although embryonal rhabdomyosarcomas (erms) represent the most common (50% - 60%) clinical form...

Like humans, songbirds learn vocal sounds from "tutors" during a sensitive period of development. Vocal learning in songbirds therefore provides a powerful model system for investigating neural mechanisms by which memories of learned vocal sounds are stored. This study examined whether NCM (caudo-medial nidopallium), a region of higher level auditory cortex in songbirds, serves as a locus where...

OBJECTIVES/HYPOTHESIS To critically review current literature comparing interventional approaches for unilateral vocal fold paralysis. STUDY DESIGN Systematic review of the literature. METHODS All English-language literature published in the PubMed database was eligible for inclusion. Inclusion criteria were: 1) the major topic must be a direct comparison of outcomes in interventions for un...
