Abstract
BACKGROUND: The minimal clinically important difference (MCID) for the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) has not been determined.OBJECTIVE: 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-June 2018 at a tertiary referral center. The average preoperative, postoperative, and change in scores were calculated for 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 mean age (SD) of 38 years (14.7) at the time of surgery. The mean postoperative follow up period (SD) was 145 days (117). The mean preoperative score (SD) for NOSE was 52 (32), SCHNOS-O score 55 (33), and SCHNOS-C score was 50 (26) points. Postoperatively, the NOSE score was 23 (22), SCHNOS-O score 24 (23), and SCHNOS-C score was 13 (18) points. The mean change in scores (SD) for NOSE, SCHNOS-O and SCHNOS-C were -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 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.CONCLUSION: For the obstruction domain SCHNOS-O, the MCID was 28 points. For the cosmetic domain SCHNOS-C, the MCID was 18 points.
