Comparison of nasal valve dysfunction treatment outcomes for temperature-controlled radiofrequency and functional rhinoplasty surgery: a systematic review and meta-analyses.

Background: Nasal valve dysfunction (NVD) is a substantial contributor to nasal airway obstruction. Minimally-invasive temp-erature-controlled radiofrequency (TCRF) treatment of the nasal valve is available and comparison with surgical techniques is warranted.
Methodology: Databases: Medline (PubMed), Embase, Cochrane Library.
Population: adults with preprocedural nasal obstruction symptom evaluation (NOSE) score >=45. Treatment effects were derived from a random effects model and reported as weighted mean difference in NOSE score between baseline; 3, 6, and 12 months postprocedure.
Results: Of 2529 initial articles, 5 studies describing TCRF treatment and 63 studies describing functional rhinoplasty were included. Pooled effect sizes for TCRF treatment and functional rhinoplasty were comparable in all analyses.
Conclusions: TCRF treatment of the internal nasal valve for NVD was associated with sustained effects comparable to functional rhinoplasty addressing the nasal valve only, rhinoplasty without concomitant turbinate treatment, and all rhinoplasty.
