Comparison of the results of frontal endoscopic lift with three incisions and deep posterior dissection and five incisions and districted dissection

Abstract

Background: This study aimed to compare the results of frontal endoscopic lift with three incisions and deep posterior dissection and five incisions with districted dissection. Methods: In a clinical trial study, 50 patients who were candidates for endoscopic lift of eyebrow and forehead were selected and randomly divided into two group of 25. The first group was operated with three incisions and deep posterior dissection and the second group was operated with five incisions with districted dissection. Characteristics and wrinkles of the forehead and eyebrow were measured before and after intervention, and compared between the two groups. Findings: Six months after operation, the mean difference of eyebrows and foreheads characteristics was higher in the group with three incisions. There was no significant difference between the two groups in the improvement of gaze and transverse claws (P = 0.110), but the improvement in glabellar crowns was significantly higher in the three incisions group; so that 63.6 of the patients in three incisions and 14.3 of patients in five incisions groups were completely improved (P = 0.004). Temporal prominence was improved in 31.8 of the patients in three incisions group, and no evidence of improvement of temporal prominence was seen in five incisions group (P = 0.013). Conclusion: Both methods, three incisions with deep dissection and five incisions with districted dissection, are effective in improving facial wrinkles. However, the improvement in some cases, including the repair of pear-shaped chin, as well as eyebrows and eyelids, are more favorable in the endoscopic lifting by three incisions and deep posterior dissection. © 2019, Isfahan University of Medical Sciences(IUMS).
