Tóm tắt

Objective: 1. Describe the clinical and radiological characteristics of patients with mandibular angle fractures (MAF); 2. Evaluate the results of treatment of the Champy technique associating with tension wire loop and the standard Champy technique in the surgical treatment of MAF.

Methods: Controlled randomized clinical trial study on 98 patients of MAF were examined and treated at the department of maxillo–facial surgery of National Institute of Odonto-Stomatology and Vietnam–Cuba Hospital in Ha Noi, from January 2008 to August 2012.

Results: MAF often coordinates with other mandibular fractures (66.3%) that the majority located in the chin area (87.5%), by traumatic force impacting on opposite mandibular body with MAF (80.6%), majority of MAF is open fractures (90.8%), unfavorable fractures (98.0%) and displaced fractures (74.5%); MAF often occurs in the left side (60.2%) and has mostly wisdom tooth in the fracture line (96.9%). The common symptoms of MAF include limited mouth opening, malocclusion, throbbing pain and bleeding torn gums in wisdom tooth. In the diagnosis of MAF, the diagnostic vulue of  CT scan is 100%; of panoramic X-ray 92.9%, of facial X-ray 96.9% and coordinating the panoramic and facial X-ray 100%. Survey on cone beam CT to measure the bone anatomical dimentions of mandibular angle region from which giving the recommended screw length and estimating the position of osteosynthesis. Evaluation at discharge, 3 and 6 months after surgery), the treatment success rates of the group II were 87.8%; 90.7% and 92.7% (in succession) and that of group I were 61.2%; 61.4% and 62.9%.

Conclusion: Early and late postoperative results showing that the Champy technique associating the tension wire loop (group II) is better the standard Champy technique (group I) statistically significant with p < 0.05.
