title: Endoscope-assisted conservative condylectomy combined with orthognathic surgery in the treatment of mandibular condylar osteochondroma.
abstract: Mandibular condylar osteochondroma (OC) results in asymmetric prognathism with facial morphologic and functional disturbance. The aim of this study was to explore the feasibility of endoscope-assisted conservative condylectomy combined with simultaneous orthognathic surgery in the treatment of condylar OC. Thirteen patients with OC of the mandibular condyle were enrolled in this study. With the aid of endoscope, condylar OC resection and conservative condylectomy were carried out via intraoral approach. A direct vision of the magnified and illuminated operative field was realized. Simultaneous orthognathic surgery was used to correct facial asymmetry and malocclusion. All patients healed uneventfully. No facial nerve injury and salivary fistula occurred. Facial symmetry and morphology were greatly improved, and stable occlusion was obtained in all cases. The patients showed no signs of recurrence and temporomandibular joint ankylosis in the 16 to 54 months of follow-up. Endoscope-assisted tumor resection and condylectomy combined with simultaneous orthognathic surgery provide us a valuable option in the treatment of mandibular condylar OC.
