OBJECTIVE In recent years numerous osteosynthesis devices have become available for the management of condylar fractures. The aim of this study was to compare and evaluate the clinical outcomes of delta plates and conventional miniplates for internal fixation of mandibular condylar fractures in adults. METHODS We performed a prospective study of 20 patients with subcondylar fractures requiring open reduction and internal fixation for their management. Patients were randomly divided into 2 groups using computer software: Group A patients (n = 10) were treated using delta plates whereas group B patients (n = 10) were treated using conventional miniplates via an extraoral retromandibular transparotid approach. RESULTS There was no statistically significant difference between delta plates and conventional miniplates for internal fixation of mandibular condylar fractures in adults. However, the time taken for adaptation of the delta plates was significantly lower than that required for the 2 miniplates (P < .001), and the ease of adaptation was significantly better for the delta plates (P < .001). CONCLUSIONS The study results indicated that the delta plate and miniplate are equally effective in terms of long-term clinical success in the management of mandibular subcondylar fractures in adults. The delta plate is superior in terms of handling characteristics, such as ease of adaptation and time required for adaptation, as only 1 plate and 4 screws are required as compared with 2 plates and 8 screws.
