We used the 18-question Glasgow Benefit Inventory (GBI) to conduct a retrospective assessment of quality of life following nasal valve surgery. We telephoned 53 patients who had undergone open rhinoplasty for the treatment of nasal valve collapse over a 2-year period. A total of 39 patients-24 men and 15 women, aged 20 to 50 years (mean: 38)-agreed to participate and answer the questions. Follow-up ranged from 3 to 12 months (mean: 8). The spectrum of possible GBI scores ranges from -100 (maximum negative outcome) to 0 (no change) to +100 (maximum benefit); in our group, the median total score was +56 (interquartile range: +32 to +90.5) and the overall total score was +58. The three subscale components of the GBI-general benefit, physical benefit, and social benefit-were analyzed individually; the respective median scores were +46 (+21 to +71), +67 (+25 to +91.5), and +50 (+17 to +100), and the respective overall scores were +60, +59, and +50. Based on these findings, we conclude that nasal valve surgery significantly improves quality of life.
