Abstract

Condyle fractures represent 20% to 30% of all mandibular fractures and are thus among the most common facial fractures. The fracture pattern can vary greatly and may occur anywhere along the line from the sigmoid notch to the mandibular angle. The main problems are access, difficulty in repositioning the extremely slender fragments, and fixation of the condyle.Eighty-seven patients were diagnosed with condylar neck or condylar base fractures from January 2007 to December 2009 in the Department of Oral & Maxillofacial Surgery of Kyung Hee University Dental Hospital. In this study, we included 35 patients who underwent open surgery and a total of 28 patients who were treated using a retromandibular transparotid approach.Surgical treatment aims were anatomic repositioning and rigid fixation of the fragments, occlusal stability, rapidly return to function, maintenance of vertical ramus dimension, no airway compromise, and reduced long-term temporomandibular joint dysfunction. Considering the high rate of occurrence of condylar fracture and the importance of the condylar as a growth center of the mandible, extraoral approaches for the open reduction of condylar fractures are considered effective and can be used widely.Short access route, easy reduction, short operating time, and stable postoperative occlusion are the advantages of the retromandibular transparotid approach. Also, there was no permanent damage from facial nerve injury, salivary leakage, or preauricular hypoesthesia. Therefore, the retromandibular transparotid approach is considered a safe and effective method for patients with a condylar neck or condylar base fracture classified according to the Strasbourg Osteosynthesis Research Group's classification, who require surgical treatment with an extraoral approach.
