Clinical Outcomes in Dorsal Preservation Rhinoplasty: A Meta-Analysis

Background: Dorsal preservation rhinoplasty (PR-D) attempts to preserve as much of the native nasal anatomy as possible when performing a hump reduction, but clinical outcomes are unclear. Objective: In patients undergoing PR-D rhinoplasty, this article investigates the rates of complications and revisions. Methods: This meta-analysis was prospectively registered on the PROSPERO database. The Pubmed, Embase, and Scopus databases were searched. Pooled incidence was calculated in a meta-analysis within a random-effects model. Results: Twenty-two studies representing a cohort of 5660 patients were included in this study. Postoperative hump recurrence rates (4.18%, 95% confidence interval [CI]: 2.41-6.40%), rates of revision rhinoplasty (3.48%, 95% CI: 1.77-5.74%), rates of postoperative nasal deviation (1.13%, 95% CI 0.37-2.28%), and rates of infection (1.89%, 95% CI: 0.35-4.62%) were all found to be low. Conclusion: PR-D has low rates of revision surgery, residual or recurrent hump, postoperative nasal deviation, and postoperative infection.
