APPLICATION STUDY OF CHAMPY’S TECHNIQUE IN SURGICAL TREATMENT OF MANDIBULAR ANGLE FRACTURE

Abstract

Background: Angle mandibular fractures are among the most common traumatic injuries of the maxillofacial region. The optimal treatment modality for angle fractures remains controversial. The present study was designed to describe the clinical and radiographic features of patients who had suffered mandibular angle fractures and evaluate the postoperative outcome in patients treated for the Champy’s technique. Materials and methods: 32 patients with 32 fractures of the mandibular angle were treated by the Champy’s technique at the department of maxillo facial surgery of Hue University of Medicine and Pharmacy and Hue Central Hospital, from April 2018 to February 2019. Evaluating of results when patients were discharged from hospital, 3 and 6 months after surgery. Results: The majority of the patients were males (84.4%). The majority of angle fractures have unfavorable fractures (96.9%) and displaced fractures (68.7%). The most common symptoms were pain, throbbing pain, mouth limited opening, swelling, malocclusion. Panoramic radiographs plays an important role in diagnosis (96.9). The patients were treated successfully according to Champy’s principle of osteosynthesis. Conclusions: The Michelet – Champy’s technique for surgical treatment of mandibular angle fractures was simple, easy to use, had high success rates and few complications. Key words: mandibular angle fracture, Champy’s technique
