Abstract:
Scarring of the vocal folds can occur as the result of blunt laryngeal trauma or, more commonly, as the result of surgical, latrogenic injury after excision or removal of vocal fold lesions. The scarring results in replacement of healthy tissue by fibrous tissue and can irrevocably alter vocal fold function and lead to a decreased or absent vocal fold mucosal wave. The assessment and treatment of persistent dysphonia in patients with vocal fold scarring presents both diagnostic and therapeutic challenges to the voice treatment team. The common causes of vocal fold scarring are described, and p

Abstract:
AbstractInjury to the vagus nerve or one of its branches during carotid endarterectomy (CEA) can result in vocal fold paralysis (VFP). This study assessed prospectively 73 patients undergoing CEA. A total of 76 procedures were performed in these patients over a one-year period. All patients underwent preoperative and post-operative assessment of vocal fold mobility by indirect laryngoscopy and/or flexible nasendoscopy. All patients had normal vocal fold mobility pre-operatively. Eight patients (10 per cent) complained of hoarseness after surgery and in three patients (four per cent) examinatio

Abstract:
One of the most important challenges in laryngological practice is the early diagnosis of laryngeal cancer. Detection of non-vibrating areas affected by neoplastic lesions of the vocal folds can be crucial in the recognition of early cancerogenous infiltration. Glottal pathologies associated with abnormal vibration patterns of the vocal folds can be detected and quantified using High-speed Videolaryngoscopy (HSV), also in subjects with severe voice disorders, and analyzed with the aid of computer image processing procedures. We present a method that enables the assessment of vocal fold patholo

Glottal area waveform, which was normalized with glottal length, was composed to quantitatively assess the overall vibratory pattern of vocal folds.

In a sense, Jorge is a prototypical individual diagnosed with autism because he provides clear-cut examples of the excesses and deficits that are often described by parents, teachers, and caregivers.

The quasi-steady approximation involves modeling the complex unsteady flow through the glottis as a sequence of steady flows through rigid orifices, which is numerically less expensive. Theoretical and experimental assessments of the quasi-steady approximation have been attempted, but contradictions in previously reported results prompt further analysis.
