INTRODUCTION In a group of persons using the voice occupationally, the frequent symptoms are hoarseness, voice fatigability and aphonia. Pathological changes in the larynx may have organic or functional character which require different methods of treatment and rehabilitation. Visualization of vibrations of the vocal folds is an essential condition for an appropriate assessment of the causes of...

INTRODUCTION Type I thyroplasty is the treatment of choice for unilateral vocal cord palsy with no spontaneous recovery. OBJECTIVES To compare the use of silastic implant with titanium vocal fold medializing implant (TVFMI®) in type I thyroplasty for unilateral vocal cord palsy with respect to subjective and objective improvement in voice, endoscopic changes in vocal cords, surgical time, and...

Monitoring cutting tool quality in the machining process is essential to success of part manufacturing. To directly monitor information tools under drilling or milling operations, this paper presents a novel 3D imaging technique enable direct geometry measurement. This method combines stroboscopy and stereoscopy, strobo-stereoscopy, which synchronizes stroboscopic illumination system with spind...

BACKGROUND The purpose of this study was to show our comparison of the quality of voice obtained after superficial transoral endoscopic cordectomies (types I, II, and III) according to the European Laryngological Society classification versus the more extended cordectomy (types IV and V) among patients with glottic precancerous lesions or early glottic cancer. METHODS Sixty-two patients under...

Aspiration has been frequently noted among patients suffering from vocal-fold paralysis. The association between a defect of glottal closure and aspiration in patients with unilateral vocal paralysis appears to have been rarely reported. The current study reviews collected data consisting of videotaped flexible nasoendoscopy and stroboscopy for patients with a unilateral vocal-fold paralysis. M...

OBJECTIVE To explore aerodynamic, acoustic, and laryngeal changes surrounding opera performance. STUDY DESIGN Prospective preperformance, postperformance, and day after performance. METHODS The laryngeal and vocal function of five male and five female classically trained singers was assessed immediately before, immediately after, and 1 day after an actual operatic performance. Phonatory thr...

The aim of the present investigation was to study hoarseness and its perceptual, acoustic and physiological characteristics in ten-year-old children’s voices. Fifty-eight children’s voices were perceptually evaluated along 15 voice parameters. The rank ordered means of each parameter revealed a discontinuity in the distribution for all parameters except pitch, breathiness and vocal fry. This di...

PURPOSE We report a case of laryngeal edema associated with the Vogt-Koyanagi-Harada (VKH) syndrome. PATIENT AND METHODS A 32-year-old African-American female presented with a 12-day prodrome, including headache, tinnitus and shortness of breath, which preceded sudden photophobia and bilateral visual loss. Examination and clinical testing were most consistent with VKH, and the patient improve...
