[Vocal fold superficial layer of lamina propria histology after the position of mucosa pediculated flap: canine experimental study].

any techniques were applied to treat patients with sulcus vocalis and scarred vocal folds. Their results were not good enough. In the Technique of Vocal Fold Pediculated Mucosa Flap, an anterior pediculated flap of vocal fold is positioned on the superficial layer of the lamina propria, below the free margin.

A contribution to simulating a three-dimensional larynx model using the finite element method.

A three-dimensional model is presented to simulate the larynx during vocalization. The finite element method is used to calculate the airflow velocity and pressure along the larynx as well as tissue displacement. It is assumed that the larynx tissue is transversely isotropic and divided into three tissues: cover, ligament, and body.

Adaptive estimation of residue signal for voice pathology diagnosis.

The use of noninvasive techniques to evaluate the larynx and vocal tract helps the speech specialists to perform accurate diagnose of diseases. In this study, a method to distinguish among 21 different pathologies using speech signals was developed. Through inverse filtering (Kalman and Wiener filters) of the voice signal, the residue was estimated and seven acoustic features were extracted from it to evaluate the laryngeal diseases.

[Congenital rubella syndrome and the occurrence of congenital heart disease].

Aiming to document the incidence and type of associated congenital heart disease, 20 children affected with the congenital rubella syndrome have been evaluated during a 5 year period, starting 1988. Congenital heart disease was detected in 45% of the cases. Persistent ductus arteriosus was the most frequent finding, followed by ventricular and atrial septal defects.

[Ankylosing temporomandibular arthritis following masseter cellulitis. 3 cases].

Treatment of temporomandibular ankylosis complicating masseter muscle cellulitis in three patients, as a result of a dental lesion, required wide excision of bone structure and, in two cases, of adjacent infected soft tissues.
