Reliability and clinical relevance of perceptual evaluation of pathological voices.

The perceptual GIRBAS scale for deviant voice quality was tested in 5 different institutes on 943 voice patients. Each voice was evaluated separately by 2 professionals. The interrater and intrarater correlation is satisfactory for G, R and B.

Differentiated perceptual evaluation of pathological voice quality: reliability and correlations with acoustic measurements.

The perceptual GRBAS scale for deviant voice quality (completed with a "I" parameter: Instability = fluctuation of voice quality over time) was tested in 5 different institutes on 943 voice patients. Each voice was evaluated separately by 2 professionals. The interrater correlation reaches 0.

[Indications for botulinum toxin in laryngectomy].

The botulinum toxin is a highly potent neurotoxin, used since several years in the treatment of the focal musculary dystonias. We define the laryngeal dystonia as a clinical entity, which is represented by a spasmodic dysphonia or an inspiratory dyspnea without dysphonia, related to a specific dystonia of the thyroarytenoid muscles. The laryngeal functional exploration (i.

[Treatment of spasmodic dysphonia with botulinum toxin].

Spasmodic dysphonia is a focal laryngeal dystonia, a rare form of dystonia. Videostroboscopy, acoustic analysis, computerized voice analysis and over all electrophysiological analysis allow for the study of the different muscles involved in this dysphonia. There are two types of spasmodic dysphonia: adductor spasmodic dysphonia and abductor spasmodic dysphonia.

[Testing and re-education of candidates for the SIVO prosthesis].

The SIVO prosthesis, developed by Pr A. Fourcin (London), is an aid to lip reading for profoundly deaf patients with residual hearing at low frequencies below 500 Hz. This prosthesis reduces the complexity of the acoustic wave of speech to sa simple sinusoidal wave, allowing better perception of the fundamental frequency of the voice and its variations, i.
