A prominent jawline creates a masculine or square face appearance that may be undesirable especially in Asian females. Asian beauty emphasises subtlety; a prominent jawline throws off the balance of midfacial structures particularly the nose and chin by overpowering the mid face. Reducing the jawline restores the balance and improves facial harmony. When it comes to the prominent jawline, patients may have a significant muscle component, bone component, or both. The aetiology of this condition is unknown. However, some of these conditions have been associated ethnicity which is commonly seen in East Asian descendants, masseter muscle hypertrophy (jaw muscle overgrowth) as a result of habitual jaw clenching, teeth grinding or diet (dried squid, tough and chewy delicacies).
Reduction angleplasty or mandibular angle reduction surgery is a cosmetic surgical procedure done to transform a square shaped face to a more delicate and feminine facial appearance. This surgical procedure is effective in correcting prominent body and angle of the lower jaw, thus reducing the width of the lower face and changing a square face to an oval or “V” shaped face. In some cases, mandible angle reduction surgery is combined with other facial contouring surgeries such as zygoma reduction, masseter muscle reduction or genioplasty to achieve facial balance. Mandible angle reduction surgery is often performed through the intraoral approach; hence there is no visible scar externally.
Patients who seek mandibular angle reduction surgery have usually had the desire to improve their appearance, and they should not attempt to mimic the Caucasian facial features. Preservation of ethnicity remains the cornerstone of this surgery, and the patient should have realistic expectations from the surgery.
