We describe our experience with reconstruction of the mandibular condyle with a costrochondral graft (CCG). We retrospectively evaluated 122 patients with diagnoses including osteoarthrosis, ankylosis, tumours, idiopathic condylar resorption, comminuted condylar fracture, and chronic osteomyelitis of the temporomandibular joint (TMJ). We used a modified preauricular approach and an endoscopically assisted technique. The grafts were followed-up by computed tomograms (CTs) and magnetic resonance (MR) examinations. All patients had successful reconstruction of the mandibular condyle with a CCG. No patient had permanent weakness of the facial nerve or any other severe complication. With its wide range of indications, the endoscopically assisted reconstruction of the mandibular condyle with a CCG through a modified preauricular approach can produce good aesthetic and functional results while reducing operating time and tissue damage.
