Eminectomía bilateral como tratamiento para luxación crónica de articulación temporomandibular. Reporte de caso / Bilateral eminectomy as a treatment for chronic temporomandibular joint dislocation. Case report

Introducción: la luxación de la articulación temporomandibular es un desplazamiento del cóndilo fuera de sus posiciones funcionales dentro de la fosa articular y la eminencia articular, la cual ocasiona una pérdida completa de la función articular. La luxación crónica es toda luxación aguda que progresa sin un tratamiento específico y que puede ser de carácter recurrente. La eminectomía es un tratamiento quirúrgico definitivo contra la luxación crónica de articulación temporomandibular. Objetivo: reportar el caso clínico de un paciente masculino, de la tercera década de su vida, con diagnóstico de luxación crónica de la articulación temporomandibular de cinco meses de evolución y presentar una revisión actualizada de la literatura sobre este procedimiento quirúrgico. Caso clínico: el paciente fue tratado quirúrgicamente con eminectomía bilateral. Discusión: la eminectomía es un procedimiento quirúrgico controversial; sin embargo, recientes investigaciones lo catalogan como seguro y efectivo. Conclusión: el caso clínico presentado muestra un buen resultado.

Background: Temporo-mandibular joint dislocation is a displacement of the condyle, out of its functional positions within the articular fossa and articular eminence, causing a complete loss of joint function. Chronic dislocation is any acute dislocation that progresses without specific treatment and that can be recurrent. Eminectomy is a definitive surgical treatment for chronic temporomandibular joint dislocation. Objective: To report the clinical case of a male patient in the third decade of his life with a diagnosis of chronic dislocation of the temporomandibular joint of 5 months of evolution and to carry out an updated review of the literature on this surgical procedure. Case Report: The patient was treated surgically with bilateral eminectomy. Discussion: Eminectomy is a controversial surgical procedure; recent research classifies it as safe and effective. Conclusion: The presented clinical case shows a good result.

Surgical Treatment Of Recurrent Tmj Dislocation By Eminectomy With Discoplasty

PURPOSE: Various treatment methods have been utilized for recurrent dislocation of the TMJ (temporomandibular joint). The purpose of this study is to define the effect of the eminectomy with discoplasty that had been performed in patients with TMJ luxation. MATERIALS AND EMTHODS: Twenty patients (22 joints), whose diagnosis were TMJ dislocation were selected in 772 patients (871 joints) who had been underwent TMJ surgery between 1988 and 2000. The selected patients were divided into two groups. Group I (12 joints) was the habitual-luxation group which involves the recurrent TMJ dislocation patients. Group II (10 joints) was the open lock-history group which involves the patients who had more than two episodes of TMJ luxation and TMJ disorders. The history of TMJ luxation, maximum mouth opening and other TMJ signs and symptoms before and after surgery were reviewed. RESULTS: In group I, one patient who had been underwent both TMJ operation had a intermittent locking, but it disappeared after post-operative 32 months. In group II, intermittent pain was present in one patient who had bruxism, but it was disappeared by splint therapy. No more TMJ dislocations and other pains were checked in other patients of group I and II. CONCLUSION: Eminectomy with discoplasty may be used to successfully treat the TMJ habitual luxation accompanied with abnormal condition of the disc-condyle complex.
