Asian faces have somewhat different characteristics that could be distinguished from those of the faces of whites in terms of both shape of the skull and facial fat. Asians usually have wide and flat faces with wide bizygomatic distance and underdeveloped premaxilla. Their facial fat is abundant around the malar and submalar regions. As the facial fat descends with aging, the Asian faces tend to be of a more rectangular and boxy shape. Along with facial tightening, more anatomically vertical, rather than oblique, repositioning of the descending facial fat is necessary to obtain more attractive angular facial shape in a rectangular face.1,2 As the malar is highlighted in a higher position with the improvement of submalar fullness and the jaw line is clearly defined by vertical repositioning of the facial fat, the facial shape can be more attractive and angular.3 We have done the extended superficial musculoaponeurotic system (SMAS) facelift technique4 with modification of the design of malar SMAS to regain attractive malar highlight without the widening of bizygomatic distance in Asian faces.

STEPS

  1. The retrotragal skin incision line and the area of skin undermining are designed.
  2. The subcutaneous flap is dissected.
  3. The malar, horizontal, and vertical SMAS flaps are designed.
  4. The malar SMAS flap is dissected from the underlying orbicularis oculi and zygomaticus minor muscle.

  • 5. The preauricular SMAS flap is dissected from the underlying sub-SMAS fat to the anterior border of the masseter muscle.

For step 5, see video, Supplemental Digital Content 2, which displays the sub-SMAS dissection in the preauricular region, preparotid region, area of lateral to masseter muscle, and around the sternocleidomastoid muscle http://links.lww.com/PRSGO/A389.

  • 6. The major retaining ligaments (zygomatic, upper, and mid masseteric ligaments) are released.

For step 6, see video, Supplemental Digital Content 3, which displays the release of the major retaining ligaments and deep fascia covering the buccal fat pad in sub-SMAS dissection, http://links.lww.com/PRSGO/A386.

  • 7. The dissected SMAS flap is vertically repositioned and fixed by the 3-0 Mersilene suture.

  • 8. The skin flap is advanced horizontally without tension.
  • 9. A suction drain is inserted.

OPERATIVE TIPS

  1. To reposition the malar fat to a higher position in wide bizygomatic patients, the malar SMAS flap is designed more laterally and cephalically (video 1).
  2. The preauricular vertical SMAS flap is designed below 4 cm from the mandibular border (video 1).
  3. The SMAS flap is dissected from the underlying sub-SMAS fat and subplatysmal fat, which covers the parotid masseteric fascia and the origin of zygomaticus major muscle (video 2).
  4. The lower platysma-SMAS flap is dissected from the fascia of the SCM muscle medially 3–4 cm to the area of loose attachment between the platysma muscle and the deep fascia5 (video 2).
  5. The upper and mid masseteric ligament is released from the undersurface of the SMAS flap, and the anterior masseteric ligaments are usually not released (video 3).
  6. The platysma-SMAS flap below the mandibular angle is sutured first upward to the level of the arch of zygoma. The malar and medial SMAS flaps can be vertically repositioned in turn as well (video 4).
  7. The SMAS flap is folded and sutured tightly (video 4).

DRESSING

Light compressive dressing is applied, and suction drain is removed on postoperative day 3.
