Composite rhytidectomy.

Signs of aging in the face reflect the change in position of deep anatomic elements, which are the platysma muscle, cheek fat, and the orbicularis oculi muscle. These changes occur from progressive ptosis of these elements, which continue to keep their intimate relationship with each other throughout the aging process. Conventional face lift procedures disrupt this normal relationship by separating the skin from these elements. All SMAS techniques reposition only the platysma muscle without repositioning the cheek fat and orbicularis muscle. This composite rhytidectomy allows elevation of a composite musculocutaneous flap containing all three elements for repositioning while maintaining their intimate relationship with each other and with the skin. One-hundred and sixty-seven composite rhytidectomies have been done with impressive results and minimal complications.

Repositioning the orbicularis oculi muscle in the composite rhytidectomy.

While blepharoplasties are routinely done with face lift procedures, the improvement is accomplished by removing excess orbital fat with eyelid skin and muscle along the incisional line. The orbicularis oculi muscle remains intact as its inferior border, which has become ptotic and redundant with aging, and actually remains in the same position following a conventional lower lid blepharoplasty and rhytidectomy. However, by elevating the orbicularis oculi with the cheek fat and platysma in a composite face lift flap, and by excising the redundant inferior border of the orbicularis muscle, a total rejuvenation of the malar area is accomplished. The descent of the orbicularis oculi muscle is in an inferolateral vector, whereas the vector of facial aging is inferomedial. Thus, repositioning the orbicularis oculi is in a superomedial vector and is obligatory in a composite rhytidectomy.

The deep-plane rhytidectomy.

Lack of significant improvement in redundant nasolabial folds has always been a problem in face lift procedures. The purpose of this paper is to describe the deep-plane rhytidectomy, which addresses the problem of laxity of the nasolabial folds. A Skoog-type sub-SMAS dissection is extended superiorly over the zygomaticus muscles and medially beyond the nasolabial folds, totally releasing all SMAS attachments and creating a thick musculocutaneous flap comprised of skin, all subcutaneous fat of the cheeks, and the platysma muscle. Four-hundred and three patients have been operated on with minimal complications. Dramatic postoperative improvements in the nasolabial folds are demonstrated, and the step-by-step techniques for the face and neck dissection are described.

The tri-plane face lift dissection.

This article reviews the author's series of 750 rhytidectomies done over an eight-year period, beginning with the earlier pure Skoog technique with no subcutaneous undermining and evolving into the present technique with widespread undermining except in the lower face. The current technique, which is a tri-plane dissection, is discussed in detail. The upper face dissection is in the subcutaneous plane. The lower face dissection is in the sub-SMAS plane and the neck dissection is in the preplatysmal plane. Ways to avoid post-operative neck deformities are discussed. The conclusion is that whether one undermines the skin of the lower face or not probably makes no difference in the aesthetic results, but this technique would appear to minimize complications, particularly hematoma formation.
