Objective: The Standardized Cosmesis Health Nasal Outcomes Survey（SCHNOS）has been demonstrated as a reliable, valid, and reproducible patient-reported outcome measure（PROM）for simultaneously evaluating nasal symptoms related to both cosmetic and functional aspects. In this study, we assessed subjective outcomes in patients who underwent septorhinoplasty using the Japanese version of SCHNOS（J-SCHNOS）and reviewed the results.
Methods: This was designed as a prospective observational study. Subjects who underwent septorhinoplasty for nasal obstruction and/or nasal deformity completed the validated J-SCHNOS questionnaire before surgery and at 3, 6, and 12 months postoperatively. Statistical analysis was performed using a mixed-effects model.
Results: The participants were 83 patients（62 men, 21 women; average age: 37.2 years）. J-SCHNOS scores improved significantly at 3, 6, and 12 months after compared with before surgery for both nasal obstruction and cosmetic aspects（p <0.001）.
Conclusions: J-SCHOS scores showed significant improvement as early as 3 months postoperatively, with sustained improvements for up to 1 year. The results suggest that J-SCHNOS is a valuable subjective evaluation tool for patients to accurately and easily report information on their nasal problems.
