    Abstract:
    PURPOSE: To determine the complication rate for patients presenting with isolated mandibular angle fractures treated by open reduction and internal fixation using a single superior border miniplate technique. PATIENTS AND METHODS: This is a retrospective study of consecutive patients with isolated mandibular angle fractures treated using a specific protocol at a Regional Oral and Maxillofacial Department between January 1998 and December 2004. Patient demographics, fracture etiology, length of hospital stay, removal of third molar, and postoperative complications were recorded. Preoperative and postoperative inferior alveolar nerve function was recorded. Objective sensory testing and patient interviews were conducted to determine the incidence of postoperative sensory deficit. RESULTS: The study population included 50 patients presenting with isolated mandibular angle fractures, 6 patients (12%) experienced complications requiring bone plate removal. These complications were minor and occurred after fracture healing as follows: 4 patients (8%) experienced superficial soft tissue infection associated with the bone plate, treated with oral antibiotics, 1 patient (2%) experienced bone plate exposure, and a further patient (2%) presented with a fractured bone plate. All 6 patients (12%) were treated by bone plate removal under general anesthesia as elective day case surgery. Thirty-nine (78%) patients had long-term sensory follow-up, mean 37 months (2 to 84 months). Permanent inferior alveolar sensory deficit (>12 months) was present in 4 (8%). Five of 26 (19%) patients with normal postinjury/preoperative sensory function had a postoperative sensory deficit. All patients in this group reported recovery of normal sensation within 6 months. CONCLUSIONS: The results of this study suggest that the complication rates associated with the treatment of isolated mandibular angle fractures using a superior border plating technique, in this patient population, is relatively low (12%). The complications were all minor in nature. There was a permanent (>12 months) inferior alveolar sensory deficit in 4 (8%) patients.
