Tratamento cirúrgico da luxação recidivante da ATM: uso de miniplaca
Abstract
Introdução: A luxação da articulação temporomandibular (ATM) ocorre quando o côndilo mandibular move-se para fora da cavidade glenóide e permanece travado anteriormente a eminência articular, sendo sua ocorrência repetitiva geralmente associada a hipermobilidade mandibular e a inclinação da eminência articular. Geralmente, é bilateral e suas características clínicas são: incapacidade de fechar a boca, depressão pré-auricular da pele, protusão do mento, salivação, dificuldade de falar, dor em graus variáveis e tensão da musculatura mastigatória. Nos casos de luxação unilateral ocorre um desvio do mento para o lado oposto. Em geral, existem duas modalidades de tratamento cirúrgico para a luxação recidivante da ATM, uma com o objetivo de restringir a abertura bucal (aumento da eminência articular com uso de anteparo) e outra com a finalidade de promover movimentos mandibulares livres (remoção da eminência articular), cada um com suas vantagens e desvantagens. Objetivo: Este trabalho discute a técnica de miniplaca (restrição do movimento do côndilo mandibular). Material e método: Apresentação de caso clínico.
UNITERMOS: articulação temporomandibular; luxações; mandíbula.
SUMMARY
Introduction: Luxation of the temporomandibular joint occurs when the mandibular condyle is displaced anterior to the articular eminence on maximal incisal opening and becomes locked in front of the eminence such that the patient cannot close the mouth again. The dislocation of the mandible is as a rule bilateral, and the symptoms are: inability to close the mouth, preauricular depression of the skin, protruding chin, tense masticatory muscles, salivation, speech difficult and more or less pain in the joints. In unilateral cases the mandible is deviating toward the opposite side from dislocation. In order to treat these patients, various methods, conservative and surgical, are described in the literature. There are two surgical approaches to treating chronic recurrent luxation of the temporomandibular joint, one restricts the opening and the other proposes free movements of the mandible. Objective: This report describes the use of miniplate as surgical procedures. Material and method: Clinical case is presented.
UNITERMS: temporomandibular joint; dislocations; mandible.
