This surgery is a mini facelift, similar to MACS lift in procedure but with the surgical area relatively confined to the low face between the preauricular area and chin. Its aim is to enhance tightening of the jawline and partially improve double chin problems. As for the procedures, Dr. Chuang first makes a short S-shaped incision from the anterior border of the earlobe to behind the ear, enters the skin’s superficial fascia, and performs subcutaneous dissection along the jawline to the corner of the mouth. If patients have concurrent chin hypertrophy requiring liposuction, liposuction can be performed through the same incision. After the limited dissection of the skin and underlying superficial fascia near the earlobe, the distal (proximal to the chin) fascia should be suspended to the proximal preauricular deep fascia for fixation and suture. This way, the peripheral skin of the chin and circumoral fat will become tight to effectively sculpt the jawline and sharpen the contour of the lower face.
This surgery boasts a small operating field and minimal invasiveness as well as rapid postoperative recovery. It is indicated for patients with congenital jawline hypertrophy, jawline laxity due to cheek collagen loss, or young patients with premature lower face aging. It may also effectively improve or prevent potential jaw skin laxity as a result of mandible reduction. This surgery has numerous indications and is appropriate for young people in particular. However, its drawback is that the surgical results are poor for patients with bulging cheek fat or severe lower face laxity due to aging. The duration of the result varies from person to person, averaging approximately 3–5 years. The S-shaped scar anterior and posterior to the earlobe gradually fades away within 6 months so that there is no obviously visible scar later.
