Traumatic Bony Ankylosis of Temporomandibular Joint as a Complication After Reduction Malarplasty

Reduction malarplasty is one of the most commonly performed cosmetic and plastic surgery in Asian countries. Bony ankylosis of the temporomandibular joint (TMJ) occurs usually as a result of trauma, infection, failed surgeries, and autoimmune diseases. Reduction malarplasty has low incidence of TMJ-related complications. A 33-year-old female patient came with complaint of restricted mouth opening around 18 mm, which was developed immediately after the reduction malarplasty 2 years before. On computed tomography image, bony adhesion and the defect from the surgical drilling were found around right TMJ. The TMJ interpositional gap arthroplasty with temporalis myofascial pedicled flap was done with simultaneous right coronoidectomy. Interincisal opening increased up to 47 mm intraoperatively.
