[Facial anatomic study and application in rhytidectomy].
OBJECTIVE
To find a procedure for facial rejuvenation which is simple, safe with lasting aesthetic results based on facial anatomic study.


METHODS
Anatomy study was performed on 12 sides from 6 head specimens. Observe the range and thickness of fat lateral to the nasolabial grooves. Observed the location of the skin retaining ligaments and reappraised their functions combining with clinical observations.


RESULTS
Skin and subcutis and SMAS (including mimic muscles) become slackening with aging, but the loosening degrees are different, especially in the region lateral to the nasolabial groove. So they should be handled respectively. The fat lateral to the nasolabial groove is thick and is mobile with aging . So the subcutaneous detachment need not beyond the anterior border of the masseter. In the past two years, we performed rhytidectomy on 100 patients by limited subcutaneous detachment and SMAS double-plication. Satisfactory results were obtained. There are no serious complications observed.


CONCLUSIONS
Rhytidectomy by limited subcutaneous detachment and SMAS double-plication is a simple and safe procedure with lasting aesthetic results.
