ABSTRACT
PURPOSE: The present study aimed to investigate the clinical efficacy of simultaneous management of condylar osteochondroma and its secondary dentofacial deformities using an intraoral surgical approach. METHODS: Six patients with condylar osteochondroma were treated with intraoral vertical ramus osteotomies and condylar resection. The free rising branch was used for reconstructing the temporomandibular joint. The simultaneous orthognathic surgery and plastic surgery were performed sequentially to correct the secondary dentofacial deformities. The indexes of aesthetic symmetry, occlusion relationship, temporomandibular joint function, condylar height, and volume change were assessed in the subsequential follow up. RESULTS: The mean follow up period was 31 months. All patients had no tumor recurrence. The ipsilateral joint function, occlusal relationship, and facial symmetry were satisfied. The ipsilateral condylar reconstruction had no obvious bone resorption and the ramus height was maintained well. Postoperative assessment showed the preoperative design was accurately fulfilled. CONCLUSIONS: The simultaneous condylar osteochondroma resection and temporomandibular joint reconstruction using intraoral approach avoids extraoral scars and correct facial asymmetry without compromising the long-term joint function and occlusal relationship.
