Orthomorphic Correction for Facial Asymmetry in a Patient With Long-Standing Temporomandibular Joint Ankylosis: A Case Report.

This case report presents the successful management of a 28-year-old female patient with facial deformity resulting from long-standing temporomandibular joint (TMJ) ankylosis. The patient underwent orthomorphic correction using a stereolithographic model of the upper and lower jaw to aid in surgical planning. The surgery was performed under general anesthesia via an intraoral approach. Cancellous bone graft harvested from the anterior iliac crest was utilized to cover the bone defect caused by the orthomorphic rotation of the lower jaw. The patient experienced satisfactory postoperative healing, and a six-month follow-up revealed significant improvement in facial symmetry and function.
