“…Two of the three facial palsy cases developed Frey syndrome at approximately 2.5 years after surgery (5.1%). Moreover, there was one case of salivary fistula, one of visible scar, and one of condylar resorption 16 (2.6%). However, no massive bleeding during surgery, hematoma, or temporomandibular joint pain after surgery were found.…”

The optimal surgical treatment of mandibular condylar fractures remains controversial 1-6 because (1) surgical treatment is difficult owing to poor visualization during surgery, (2) it may cause postoperative complications including facial palsy, 7 and (3) closed reduction can also achieve good occlusion. [8][9][10] The Innsbruck-style retromandibular anterior trans-parotid (RAT) approach and a triangular-positioned double mini-plate osteosynthesis (TDO) technique have been reported by Dalla Torre et al. from Innsbruck, Austria. This technique allows direct visualization and is associated with lower incidence of facial palsy. 11 This study reviewed the details of mandibular condylar neck and base fractures treated using the Innsbruckstyle RAT approach and TDO technique. MATERIALS AND METHODSA retrospective review of the records, radiographs, and computed tomography scans of patients who had undergone surgery using the RAT approach and the TDO technique between May 2016 and March 2020 was conducted at the department of oral and maxillofacial surgery, Tokyo Women's Medical University Hospital (TWMU), and department of plastic and reconstructive surgery, Tokyo Metropolitan Police Hospital (TMPH) in Tokyo. All cases Craniofacial/Pediatric Original artiCleBackground: The retromandibular anterior trans-parotid (RAT) approach and a triangular-positioned double mini-plate osteosynthesis (TDO) technique have been reported from Innsbruck Medical University. This minimally invasive technique involves direct visualization of the condyle and is associated with lower incidence of facial palsy. Methods: A retrospective review was performed on the RAT approach and TDO technique conducted by a surgeon and team at two hospitals in Tokyo during a period of 3 years and 10 months. Results: This technique was performed on 35 patients with 39 condylar fractures. Sixty-nine percent of cases were due to accidental fall, 17% to traffic accidents, and 9% to sports. Furthermore, 92% cases were condylar base fractures. Nighty-seven percent of cases achieved good occlusion. The mean maximum mouth opening was 49 ± 1.3 mm. Postoperatively, facial palsy developed in three patients (7.7%), and two of them developed Frey syndrome at approximately 2.5 years postoperatively (5.1%). All patients completely recovered within 3 months postoperatively. One case each of salivary fistula, visible scar, and condylar resorption was found (2.6%). No case of massive bleeding during surgery, hematoma, or TMJ pain after surgery was found. Conclusion:This technique could achieve good occlusion with low incidence of complications and could contribute to early social reintegration among patients.
