Abstract: Objective: The Standardized Cosmesis and Health Nasal Outcomes Survey is a validated instrument for patients undergoing rhinoplasty surgery. The aim of this study was to validate a Dutch-language version of the Standardized Cosmesis and Health Nasal Outcomes Survey. Methods: The Standardized Cosmesis and Health Nasal Outcomes Survey was translated and back-translated and 10 Dutch-speaking rhinoplasty patients were interviewed to evaluate the translation. The translated version was administered to 25 rhinoplasty patients (cases) and 25 controls at 2-week intervals. The internal consistency, test-retest reliability, and factor structure of Standardized Cosmesis and Health Nasal Outcomes Survey were measured. Results: Both the obstructive domain of the Standardized Cosmesis and Health Nasal Outcomes Survey and the cosmetic domain showed a high internal consistency, alpha 0.94 and 0.95, respectively. The Standardized Cosmesis and Health Nasal Outcomes Survey was reliable showing very strong test-retest correlations of 0.93 for Standardized Cosmesis and Health Nasal Outcomes Survey-obstructive domain and 0.94 for Standardized Cosmesis and Health Nasal Outcomes Survey-cosmetic domain, respectively. The Wilcoxon rank-sum test showed a significant difference between cases and controls for the Standardized Cosmesis and Health Nasal Outcomes Survey-cosmetic domain (P =.0001) but not for the Standardized Cosmesis and Health Nasal Outcomes Survey-obstructive domain (P =.1 4). Exploratory factor analysis showed unidimen-sionality for both the Standardized Cosmesis and Health Nasal Outcomes Survey-cosmetic domain and the Standardized Cosmesis and Health Nasal Outcomes Survey-obstructive domain. Conclusion: The Standardized Cosmesis and Health Nasal Outcomes Survey was successfully translated, culturally adopted, and validated for its use in a Dutch-speaking population of rhinoplasty patients.
