Complications Associated with Rhinoplasty: An Umbrella Review of Meta-analyses.

[BACKGROUND] An increasing number of studies have investigated the effect of various methods in avoiding complications in rhinoplasty. Our study aims to analyze the connections between various choices in rhinoplasty and the rate of multiple complications by summarizing results in related meta-analyses.

[MATERIALS AND METHODS] Through Pubmed, MEDLINE, Embase, and the Cochrane Database were associated systematic reviews searched to gather and review the available evidence of different plans and health outcomes in rhinoplasty for this umbrella review.

[RESULTS] The study included 14 systematic reviews with 128 meta-analyses of randomized clinical trials. Edema and ecchymosis were the two most investigated outcomes. The implementations of steroid, tranexamic acid, periosteal preservation, external approach in lateral osteotomy, and piezoelectric osteotomy were linked with significantly lower incidence of several complications. Multiple administration of steroids was found to be associated with fewer complications in a prolonged time.

[CONCLUSIONS] With summarized evidence of complications related to rhinoplasty, this research can help surgeons to avert patients from suffering complications and optimize cosmetic outcomes.
