Abstract: Objective: To investigate the safety and efficiency of surgical treatment for subcondylar fractures though intraoral approach. Methods: This is a retrospective study of patients with subcondylar fractures who underwent surgical open reduction and internal fixation through intraoral approach in our department from January 2014 to April 2016. Results: Eight patients with 10 subcondylar fractures were treated, 5 of which were associated with mandibular body fractures. All of them underwent treatment of surgical open reduction and internal fixation by transbucal instrument or angular screwdriver though intraoral approach. All patients healed by first intention, and no patients were observed facial paralysis and salivary fistula. Orthopantomography and 3DCT showed that apposition of fractures were good. After 3 months, no obvious scars were observed on facial incision, and X-ray showed subcondylar fractures anatomical reduction. Conclusion: There is advantageous in an intraoral and transoral or angular screwdriver approach than preauricular, retromandibular or submandibular approaches, such as small incision, satisfactory appearance and quick recovery. Fracture reduction and fixation can be performed by using the endoscope. It is a safe and efficient approach for open reduction and internal fixation of subcondylar fracture.
