Functional Outcomes of Dorsal Preservation Rhinoplasty: A Systematic Review and Meta-Analysis

Introduction: Preservation rhinoplasty is an increasingly popular alternative to structural rhinoplasty. However, concerns remain regarding potential nasal airway narrowing and the limited availability of objective postoperative functional data. Objectives and Hypotheses: To review and analyse current studies assessing functional outcomes of preservation rhinoplasty, with or without comparison to structural rhinoplasty. Study Design: Systematic review and meta analysis of functional outcomes in preservation rhinoplasty. Methods: A comprehensive database search identified studies using key words. Eligible studies that were included reported original quantitative data using validated functional outcome measures (NOSE, SCHNOS-O, VAS-F, SNOT-22, or rhinometry). Results: Twenty-two studies (n = 2058) met inclusion criteria. Controlled studies showed no significant difference between preservation and structural rhinoplasty outcomes, while uncontrolled studies demonstrated postoperative improvement from baseline. Conclusions: Preservation and structural rhinoplasty yield comparable functional results, both significantly improving validated patient-reported outcome measures.
