[The study of combined unilateral intraoral and extraoral reduction approach in the treatment of anterior temporo-mandibular joint dislocation].

OBJECTIVE: To observe the clinical outcomes of a combined unilateral intraoral and extraoral reduction approach in the treatment of anterior temporomandibular joint (TMJ) dislocation. METHODS: Postural muscular chains were utilized in the biomechanical analysis of stomatognathic systems for improving TMJ repositioning approaches. A total of 87 patients with anterior TMJ dislocation were included in the present study. A combined unilateral intraoral and extraoral reduction approach was applied, and the clinical effects were evaluated. RESULTS: Biomechanical analysis reveal that reflexive contrac-tion of the maxillary muscle group was blocked sufficiently during the combined unilateral intraoral and extraoral reduction process. All dislocated TMJs were set successfully and efficiently with few complications. CONCLUSIONS: Combined unilateral intraoral and extraoral reduction approach is an effective, convenient, and minimally invasive way to treat anterior TMJ dislo-cations.
