Abstract
There are several manners for surgical approaches to the mandibular condyle. With the retromandiular approach, the condyle and fracture are exposed directly and allow for good inspection and reduction. The retromandibular scar is very well camouflaged and practically invisible. The aim of this study was to evaluate clinical results of retromandibular approach for the reduction and fixation of fractured mandibular condyles. We described postoperative complications such as temporary facial nerve weakness involving the marginal mandibular branch, mouth opening limitation and malocclusion in 13 patients with mandubular condylar fractures; 11 subcondylar fractures and 2 condylar neck fractures. The follow-up period was longer than 6 months in all patients. The retromandibular approach was successful in all subcondylar fracture cases. 2 patients with condylar neck fracture had mouth opening limitation and temporary marginal nerve palsy longer than 3 months. But there were no cases of permanent nerve injury and malocclusion. Our findings indicate that retromandibular approach is an easy and safe technique for subcondylar fracture but not for condylar neck fracture.
