Endoscopic approach to the ramus/condyle unit: Clinical applications

Abstract

Purpose: The purpose of this report is to describe use of an endoscopic technique for exposure of the mandibular ramus/condyle unit (RCU) to facilitate reconstructive jaw procedures. Patients and Methods: This is a retrospective evaluation of 10 patients with diagnoses of idiopathic condylar resorption (n = 2), subcondylar fracture (n = 5), mandibular prognathism (n = 1), condylar hyperplasia (n = 1), and mandibular asymmetry (n = 1), who underwent endoscopic exposure of the RCU. Results: All 10 patients had successful reconstruction of the RCU using the endoscopic approach. The procedures performed included the following: condylectomy (n = 5 sides), costochondral graft reconstruction (n = 4 sides), reduction of subcondylar fracture (n = 5 sides), and mandibular ramus osteotomy (n = 4 sides). Mean operating time was 84 minutes. No patients had marginal mandibular nerve weakness or other complications. Conclusion: This case series demonstrates the feasibility of endoscopic access to the RCU. The procedures can be performed with no increase in operative time and with minimal morbidity. © 2001 American Association of Oral and Maxillofacial Surgeons
