RESUMO
BACKGROUND: Reoperative face lift can be technically more demanding than primary face lift because of altered anatomy and scarred tissue plane. This study was carried out to analyze the outcome of reoperative face lift using sub-superficial musculoaponeurotic system (SMAS) techniques, including facial nerve injury. METHODS: Seventy reoperative face lifts using sub-SMAS techniques were studied. Data analysis includes the patients' demographic information, the interval between the previous face lift and the reoperative face lift, intraoperative findings of the SMAS-platysma anatomy, complications, and rate of revision. A separate group of 180 primary face lifts using sub-SMAS techniques during the same period was analyzed for the incidence of facial nerve injury only. RESULTS: Intraoperative findings in the reoperative group consist of anatomical changes in the SMAS-platysma in 82.9 percent of the cases, including increased fibrosis, changes in thickness, limited movement, and increased adhesion on the undersurface. Sub-SMAS dissection was completed in 137 hemifaces. Complication consists of seroma (1.4 percent), delayed healing (1.4 percent), and temporary facial nerve injury (7.1 percent), which was not correlated with increased fibrosis or adhesion under the SMAS-platysma. The rate of revision within 18 months was 11.4 percent. There was a 2.2 percent incidence of temporary facial nerve injury in the primary face-lift group. CONCLUSIONS: Sub-SMAS techniques, with few exceptions, were successfully used in a series of reoperative face lifts. Temporary facial nerve injury was the most frequent complication. Satisfactory outcome was obtained in all the cases. The incidence of facial nerve injury was higher than in primary face lift using sub-SMAS techniques. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
