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

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.

Diagnosis of PVFM requires a multidisciplinary approach.

Abstract:

Neuralgic Amyotrophy (NA) is a rare disturb of the peripheral nervous system that can include extreme pain, multifocal paresis and atrophy of the muscles of the upper limbs. When the nerves located outside of the brachial plexus are involved, the term Neuralgic Amyotrophy Extended (ANE) is used. Diagnosis of NA is clinical and has a series of inclusion and compatibility criteria established by the European CMT Consortium. On this study the clinical history, multidimensional vocal assessment data and the vocal techniques used in five-weeks voice therapy for one patient, professional voice, with

Objectives. The purpose of this study was to quantify the size of vocal fold polyps and to investigate the relationship between the glottal gap and parameters of acoustic voice analysis and phonetography. Material and methods. Eighty-one microlaryngoscopic images and digital recordings of voices (acoustic analysis and phonetogram) acquired from the patients with vocal fold polyps (VFPs) were employed in this study. Vocal fold (VF) images were collected during routine direct microlaryngoscopy using Moller-Wedel Universa 300 surgical microscope, 3-CCD Elmo 768×576- pixel color video camera and a

Abstract:

Examination of the surface wave properties of the vocal fold mucosa is becoming an important part of assessment of vocal function. A key wave property is propagation velocity, which determines the phase delay between the upper and lower margins of the vocal folds. Excised canine larynges were used to measure this phase delay, and therewith propagation velocity. The motion of two flesh points was tracked stroboscopically. Differential displacements between the flesh points were matched to displacements of a model. A least-squared fit of the data to the model provided the numeric values of propa

Abstract:

Assessment of laryngeal framework surgery requires an awareness of the effect of vocal fold mass, stiffness, and position on voice production. The vibratory pattern of the vocal folds during phonation depends on the subglottic pressure as well as the mass and stiffness of the folds. To assess the effect of variations in vocal fold tension with contraction of the cricothyroid muscle on phonation, eight mongrel dog larynges were studied in vivo. Photoglottography, electroglottography, and subglottic pressure were simultaneously recorded as airflow rate and superior laryngeal nerve (SLN) stimulat

Abstract:

Poland has about 25000–30000 thyroid glands operations per year. These kind of operations are in fourth place as to the frequency of scheduled operations. Most patients have total thyroidectomy. In addition to the classic method of accessing the collar cut at the neck, there are also alternative access, e.g. through the vestibule of the mouth or armpit. Surgery carries the risk of serious and even life-threatening consequences. One of the most serious complications of this surgery is failure of one or both laryngeal recurrents nerves. Laryngeal recurrents nerves are responsible for the proper
