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.
