Objective. To assess the outcomes of functional rhinoplasty for nasal valve incompetence and to evaluate an in-office test used to select appropriate surgical techniques. Methods. Patients with nasal obstruction due to nasal valve incompetence were enrolled. The modified Cottle maneuver was used to assess the internal and external nasal valves to help select the appropriate surgical method. The rhinoplasty outcomes evaluation (ROE) form and a 10-point visual analog scale (VAS) of nasal breathing were used to compare preoperative and postoperative symptoms. Results. Forty-nine patients underwent functional rhinoplasty evaluation. Of those, 35 isolated batten or spreader grafts were inserted without additional procedures. Overall mean ROE score increased significantly () from 41.9 ± 2.4 to 81.7 ± 2.5 after surgery. Subjective improvement in nasal breathing was also observed with the VAS (mean improvement of 4.5 (95% CI 3.8–5.2) from baseline ()). Spearman rank correlation between predicted outcomes using the modified Cottle maneuver and postoperative outcomes was strong for the internal nasal valve (Rho = 0.80; ) and moderate for the external nasal valve (Rho = 0.50; ). Conclusion. Functional rhinoplasty improved subjective nasal airflow in our population. The modified Cottle maneuver was effective in predicting positive surgical outcomes.
