Overgrowth of a costochondral graft in temporomandibular joint reconstructive surgery: An uncommon complication

A 16-year-old girl had a history of unilateral ankylosis of the temporomandibular joint, which was reconstructed with an autogenous costochondral graft. About 2.5 years after surgery, the patient presented with overgrowth of the costochondral graft, resulting in deviation of the jaw toward the unaffected side.
