Background: East Asian faces vary in shape but only oval faces seem to be considered attractive. Many patients with wide faces seek removal of part of the mandibular angle and/or zygoma to achieve an ideal facial contour, but the procedure is high risk and the recovery period is relatively protracted.
Objectives: We sought to achieve ideal facial contours through the use of autologous fat grafting (AFG) combined with masseter botulinum toxin (BTX) injection for patients with wide faces and masseter hypertrophy.
Methods: Fourteen patients with wide faces underwent AFG of the forehead, temporal region, cheeks, zygomatic body, nose, nasolabial fold, tear trough, and chin; and BTX injection into the masseter muscles. Each patient was photographed more than 6 months after the operation. The pre- and postoperative ratios pertaining to the facial aesthetics of the face were calculated. The Hollowness Severity Rating Scale (HSRS) and Ricketts's E-line were used to evaluate the photographs. Patient satisfaction was also investigated.
Results: All patients received AFG and 1 to 3 BTX injections. The face length:bizygomatic breadth, bigonial breadth:bizygomatic breadth, and lower-face height:middle-face height ratios improved greatly after treatment. The mean HSRS score decreased from 2.214 preoperatively to 1.071 postoperatively. The chin and nose became more prominent than before. Facial swelling persisted for an average of 11.929 days. All patients were satisfied with the treatment outcome.
Conclusions: A combination of AFG and BTX injection was able to achieve an ideal oval face in East Asian patients with wide faces and masseter hypertrophy, with very few complications. Recovery was rapid and patient satisfaction was high.
