Complications in endoscopic-assisted open reduction and internal fixation of mandibular condyle fractures.

Endoscopic-assisted open reduction and internal fixation (EAORIF) of subcondylar fractures is minimally invasive, provides excellent visibility without a large incision, and reduces surgical scarring and the risk of facial nerve injury. This study evaluated the complications associated with EAORIF. Twenty-six patients underwent EAORIF for mandibular condyle fractures. The postoperative follow-up period was longer than 6 months. We analyzed associations between the complication incidence and the number of fixation plates, accompanying mandibular fractures, and age. Eighteen (69.2%) and 6 (23.1%) patients had temporary (<3 months after surgery) and long-term (>6 months after surgery) complications, respectively. Patients older than 30 years had complications more frequently than those younger than 30 years. Complication rates were similar for different numbers of fixation plates and among patients with and without accompanying mandibular fractures. EAORIF is a reliable technique for treating condylar fractures, regardless of patient age, number of fixation plates, or accompanying mandibular fractures. However, improvements are needed to reduce long-term complications.
