AB  - BACKGROUND: The minimal clinically important difference (MCID) for the 
      Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) has not been 
      determined. OBJECTIVES: The authors sought to define the MCID for both domains of 
      the SCHNOS questionnaire. METHODS: This prospective cohort study included 
      patients who underwent functional, cosmetic, or combined rhinoplasty operation 
      from June 2017 to June 2018 at a tertiary referral center. The average 
      preoperative, postoperative, and change in scores were calculated for the nasal 
      obstruction symptom evaluation scale (NOSE) and SCHNOS. Anchor-based MCIDs were 
      estimated for both SCHNOS subscales to define change in obstruction and cosmesis 
      perceived after the rhinoplasty. RESULTS: Eighty-seven patients (69% women, 31% 
      males) with a mean age (standard deviation [SD]) of 38 years (14.7) at the time 
      of surgery were included. The mean postoperative follow-up period (SD) was 145 
      days (117). The mean preoperative score (SD) for the NOSE was 52 (32), SCHNOS for 
      nasal obstruction (SCHNOS-O) score was 55 (33), and SCHNOS for nasal cosmesis 
      (SCHNOS-C) score was 50 (26) points. Postoperatively, the NOSE score was 23 (22), 
      SCHNOS-O score was 24 (23), and SCHNOS-C score was 13 (18) points. The mean 
      change in scores (SD) for NOSE, SCHNOS-O, and SCHNOS-C was -29 (37), -31 (38), 
      and -37 (28), respectively. The calculated MCID for SCHNOS-O was 26 (16) and for 
      SCHNOS-C was 22 (15) points. The MCID for NOSE was 24 (13) points. A sensitivity 
      test for the patients with a follow-up >/=3 months showed only slightly different 
      MCID estimates: 28 (17) for SCHNOS-O, 18 (13) for SCHNOS-C, and 24 (15) points 
      for NOSE. CONCLUSIONS: For the obstruction domain SCHNOS-O, the MCID was 28 
      points. For the cosmetic domain SCHNOS-C, the MCID was 18 points.
