N2 - Mandibular condylar hyperplasia is a rare disorder, characterized by unilateral mandibular overgrowth with overeruption of the dentition on the affected side. Although the etiology is unclear, multiple surgical techniques have been described to correct the associated mandibular bone, occlusal, and soft tissue deformities. Often a condylectomy, to arrest mandibular growth, is combined with various orthognathic procedures to restore occlusion and facial harmony. Here we report our technique of isolated high condylectomy with simultaneous intraoral placement of maxillary and mandibular miniplates. Each plate has an intraoral extension that allows our orthodontists to develop vertical force vectors to intrude the maxillary and mandibular molar segments. Using this combined surgical and orthodontic technique, we were able to postoperatively control the occlusal cant, restore the dental midline, improve facial aesthetics, and resolve the patient's contralateral temporomandibular joint dysfunction without concomitant orthognathic surgery. As a result of our findings, we are currently using, and would recommend, this technique for patients requiring surgical-orthodontic intervention for other conditions.
