Diferencias anatomoquirúrgicas de ritidectomía supra-high SMAS vs ritidectomía con plicatura del SMAS en tres vectores

Descriptions have been provided for multiple rhytidectomy techniques, some with greater manipulation of the tissues and; therefore, longer surgical time, slower recovery and greater probability of complications related to the procedure. We describe the pathological anatomy of two widely used rhytidectomy techniques: supra-high SMAS and SMAS plication. Next, we compare aesthetic satisfaction retrospectively, intraoperative duration, speed of recovery, and probability of related complications during follow-up. We carried out a retrospective, comparative, observational longitudinal study in 19 cases of SMAS plication and 20 supra-high SMAS controls. The homogenization of the data was analyzed with the χ 2 and Fisher tests, and we used the Odds Ratio (OR, 95% CI) as a measure of association between the surgical technique used and the probability of having complications. There was no statistically signi fi cant di ff erence between the technique used and the probability of presenting an aesthetic satisfaction ≥ 80%, OR = 0.93 (95% CI, 0.22-1.42). There was also no statistically signi fi cant di ff erence between the technique used and the probability of not having postoperative complications, OR = 2.13 (95% CI, 0.34-13.24). Both the supra-high SMAS rhytidectomy and SMAS plication are previously known and widely used rhytidectomy techniques. There are no signi fi cant di ff erences in terms of aesthetic satisfaction or in the probability of having complications; however, the patients with SMAS plication were operated in a shorter time and recovered more quickly.
