Hyperplastic aberrations are differently classified and the term of precancerosis diversely interpreted; therefore, it is extremely difficult to evaluate the effectiveness of particular therapeutic methods. A standardized classication would enable an objective assessment of the treatment for precanceroses. Our own conception of the histologic patterns in precanceroses is presented. In the perio...

Background: Video stroboscopy has been the only way to visualize vocal fold movement for more than 50 years. Now we can capture the true movement of the vocal folds with high-speed recordings. Objective: A prospective randomized study was made to show if high speed films gave supplementary information that was better than video stroboscopy for diseases of the laryngeal function. Method: Randomi...

We present in-vivo 3D human vocal fold images with polarization sensitive optical coherence tomography (PS-OCT). Characterizing the extent and location of vocal fold lesions provides useful information in guiding surgeons during phonomicrosurgery. Previous studies showed that PS-OCT imaging can distinguish vocal fold lesions from normal tissue, but these studies were limited to 2D cross-section...

OBJECTIVES/HYPOTHESIS This study assessed the long-term efficacy and recurrence rates of percutaneous steroid injections (PSIs) for benign vocal fold lesions. STUDY DESIGN Prospective clinical study. METHODS A prospective human clinical trial was performed from October 2008 to September 2014 at Soonchunhyang University Hospital, Bucheon, Korea. Percutaneous steroid injection was performed i...

The paper presented a three-dimensional, first-principle based fluid-structure-acoustics interaction computer model of voice production, which employed a more realistic human laryngeal and vocal tract geometries. Self-sustained vibrations, important convergent-divergent vibration pattern of the vocal folds, and entrainment of the two dominant vibratory modes were captured. Voice quality-associa...

OBJECTIVE To assess the effectiveness and identify vocal fold leukoplakia types appropriate for nonsurgical treatment. METHODS The vocal fold leukoplakia in 178 patients was divided by gross appearance into three subtypes: flat and smooth, elevated and smooth, and rough. All patients received nonsurgical treatment including smoking and drinking cessation, voice rest, omeprazole, and Chinese m...

Method A prospective observational study involving 80 patients aged ≥ 18 years, diagnosed with severe asthma. After anamnesis, physical examination, and application of a questionnaire with 6 questions to identify vocal cord dysfunction. Then patients underwent spirometry and laryngoscopy. On the basis of the laryngoscopic findings, we created three patient groups: vocal cord dysfunctio...

The vocalizations of cattle provide conspecifics with meaningful information about the caller. If we can learn how to interpret this information correctly, it could be used to improve management and welfare assessment. Vocalization may be viewed as a subjective commentary, by an individual, on its own internal state. The vocal behaviour of cattle is potentially a useful indicator of their physi...

Describing unidentified sounds with words is a frustrating task and vocally imitating them is often a convenient way to address the issue. This article reports on a study that compared the effectiveness of vocal imitations and verbalizations to communicate different referent sounds. The stimuli included mechanical and synthesized sounds and were selected on the basis of participants' confidence...

Upper airway obstruction can mimic bronchial asthma. A particular type results from psychogenic dysfunction of the vocal cord, and presents as bronchial asthma or organic upper airways obstruction. If not recognized, ineffective and potentially harmful therapy is given instead of focusing on the underlying psychopathology. We report three Saudi females with this condition, in whom polygamy and ...
