抄録

The surgical reduction and plate fixation of a condylar fracture can lead to early recovery, but the extraoral approach might induce complications, such as facial nerve injury and the creation of visible scars. Recently, an endoscopically-assisted intraoral approach has been introduced to avoid these complications, and we performed this procedure in two cases with subcondylar fractures. Case 1: A 33-year-old female had subcondylar and mandibular body fractures due to a traffic-related injury. She had hearing loss and visual impairment. Case 2: An 84-year-old female had subcondylar and mandibular body fractures due to a traffic-related injury. She had dementia and delirium. Both patients had difficulty communicating, and surgical treatments were performed to enable early recovery. An endoscope with a 30-degree angle was used to visualize the condylar fracture through an intraoral incision. Titanium miniplates and screws were used to stabilize the fracture site with the help of a contra-angle drill and screwdriver. The intermaxillary fixation was released on the seventh and fifth postoperative days, respectively. This surgical procedure is minimally invasive and can lead to an early recovery, and so can be a useful method for treating condylar fractures, if the patients and indications are properly selected.
