Abstract

The safety and efficacy of extracorporeal septoplasty (ECS) has long been debated. Our objective was to determine this technique's functional and aesthetic outcomes and complications through a systematic review of the literature. PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science databases were evaluated for studies detailing functional or aesthetic outcomes of ECS. Bias was evaluated using the Cochrane Risk of Bias Tool and the Methodological Index for Non-randomized Studies (MINORS) score. Aesthetic and functional outcomes in addition to complications were evaluated using subjective and objective measures. Meta-analyses were performed when appropriate. Seventeen studies encompassing 1418 patients were included. The average MINORS score for observational studies was 9.2. Overall there was a significant improvement in subjective nasal function with a preoperative average Nasal Obstruction Symptom Evaluation (NOSE) score of 75 (±16) decreasing to 19.5 (±16.5) postoperatively for a mean difference (MD) of -55 (95% confidence interval (CI): -60 to -49.5). In terms of objective nasal function, at 6 months postoperatively, there was an improvement of nasal flow measured by rhinometry ranging from 70 to 71% across studies. Anthropometric measurements were utilized for objective aesthetic outcomes. There was a significant improvement in I-shaped deviations (MD: -2.7°, 95% CI: -5.6 to -0.16) and C-shaped deviations improved by 11.9° (95% CI +2.8-+21.2). Complication rates ranged from 0 to 18%. ECS can achieve significant improvements in the subjective and objective function of the nose. The associated complication rate is low but variable between surgeons.
