The multi-vectored rhytidoplasty

CHAPTER 13 The multi-vectored rhytidoplasty



Jack A. Friedland


The stigmata of facial aging are well known. They include loss of elasticity and laxity of the cheeks, jowl formation, perioral wrinkles, platysmal bands, and laxity of cervical skin. The possible combinations are infinite, and each patient must be carefully analyzed to formulate a treatment plan. Our challenge as plastic surgeons is to recreate harmony between facial regions and to balance and smoothly blend the transition between these regions. It is important to ascertain what patients looked like early in their lives. Several questions then arise for the plastic surgeon. Do the patients themselves remember? Do we restore their youthful appearance? Do we make them look different, or even better? It is also important to keep in mind that not everyone needs to have everything corrected.


My goals in choosing a procedure for facial rejuvenation are:



• It must provide reproducible results with repeated use.


• It must allow familiarity with easily mastered techniques.


• It must be able to be performed in a reasonable time at a reasonable cost.


• It must meet the patient’s goals.


• The technique must be equally applicable for primary and secondary procedures.


The outer layers of the face are similar to a theater curtain in the front of a stage. The curtains are made of two layers – an outer surface (skin) and an inner lining (subcutaneous tissue) which are intimately adherent. The curtain moves by ropes or cables attached at the top and medial side with forces exerted for movement in superior and lateral vectors. Unlike the theater curtain, the face is different, because the contiguous external tissues are attached to the bony skeleton in several areas by strong osseocutaneous ligaments for support and suspension. The muscles of facial expression insert into the skin and move it in vectors perpendicular to their long axis. With the loss of elasticity and thinning of the skin seen in aging, the repetitive movements over time cause wrinkling of the skin perpendicular to the vector of pull of the muscles of facial expression. To correct this problem it is necessary to dissect the skin and subcutaneous tissues from their attachments to the underlying SMAS, releasing the attachments of the osseocutaneous ligaments, and redraping each as a separate vector. If this is not done, the initial good correction will fail and not be long-lasting.


If a foreheadplasty is to be included in the overall plan for facial rejuvenation it is performed primarily, followed by eyelidplasties, and then the facialplasty. Patients are placed under deep sedation with local anesthesia, or more often, they are administered general anesthesia by an anesthesiologist, utilizing narcotic sedation and a continuous propofol drip. Often they are intubated with a laryngeal mask or an endotracheal tube. Prior to performance of the facialplasty, both sides of the face and neck are injected with image xylocaine with 1 : 200,000 epinephrine.


The facialplasty is begun by undermining the right side of the face and neck and then the left side. The submental, anterior, and lateral aspects of the neck are undermined and defatted as necessary. Bands may be excised vertically and/or transected transversely (inferiorly), and then the SMAS in the left and right cheeks and neck is tightened. Finally, the submental incision is closed and the flaps on the right and left sides of the face and neck are redraped, the excess skin is excised and the incisions are closed. The incisions must be placed so that they will heal well, and great attention to technique and detail will result in scars that will be almost imperceptible. It does not matter how long the scar is, it matters where it is, and how it looks! (see Fig. 13.1).

Laxity in the lower face and submental areas develops because of loss of support from the SMAS, and especially because of loss of elasticity of the skin and its attachments to the deeper tissues, except where attached to the facial skeleton by the osseocutaneous ligaments. These ligaments do not become lax with time and are the cause for some of the deformities seen in the aging face due to the descensus of the soft tissues, such as the lateral perioral labiomandibular creases and formation of jowls. Therefore it is important to release the zygomatic and mandibular osseocutaneous ligaments (see Figs 13.2, 13.3, and 13.4).
