Remodeling of Neocondyle

Abstract

Temporomandibular joint (TMJ) ankylosis in children is one of the most complex and challenging problems managed by oral and maxillofacial surgeons. TMJ ankylosis in growing children often leads to facial deformity, difficulty in chewing and swallowing, severe malocclusion, poor oral hygiene, multiple decayed teeth, and impairment of speech. A good functional and esthetic outcome can be achieved after reconstruction with the autogenous grafts. Here, we present a case of a 9-year-old patient treated with condylectomy and ipsilateral coronoidectomy, followed by reconstruction with costochondral graft with 5 years of follow-up. During this period, the reconstructed graft remodeled into a neocondyle and also regrowth of the coronoid process. The mouth opening and facial symmetry were acceptable.
