This study demonstrated that lower-lid malposition or abnormal function after lower-lid blepharoplasty cannot be explained by denervation of the zygomatic branch of the facial nerve. Any acute or residual denervation seen in the subciliary orbicularis is not clinically significant. The importance of lower-lid support and canthal anchoring cannot be emphasized enough in preventing lower-lid malposition. Blepharoplasty is a challenging procedure that requires careful preoperative planning, intraoperative reassessment, and meticulous surgical technique to optimize facial rejuvenation and patient safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
