Abstract: ObjectiveTo describe the use of endoscopic technique for exposure of the mandibular ramus-condyle unit(RCU) to facilitate reduction and rigid fixation of the fractures.MethodsSixteen patients ( 18 sides) with diagnosis of subcondylar fracture ( 11 sides),condylar neck fracture ( 2 sides ),and mandibular ramus fracture (5 sides ),who underwent endoscopic exposure of the RCU and fixation with miniplates by an extraoral or transoral approach.Six sides were no displacement,10 sides were obvious displacement,and 2 sides were dislocation.ResultsAll patients had successful treatment of fractures of the mandibular RCU,all patients showed quick recovery to preinjury occlusion.Followed up 12-36 months,normal temporomandibular joint function was noted in all patients.No patient had marginal mandibular nerve weakness or other complications.ConclusionsIt demonstrates the feasibility of endoscopic access to the RCU for treatment of the fractures.The procedures can be performed with minimal morbidity and functional impairment.
