Introduction: Rhinoseptoplasty procedures are focused not only on the aesthetic but also on the functional aspects. Surgical outcomes have to be evaluated in each patient. To date, the Polish literature has lacked a tool facilitating simultaneous assessment of rhinoseptoplasty’s impact on both the external appearance and functionality of the nose.Aim: The aim of this study was to translate, adapt, and validate the Polish version of the original SCHNOS (Standardized Cosmesis and Health Nasal Outcomes Survey) questionnaire as used for the assessment of the functional and aesthetic outcomes in patients after rhinoplasty.Materials and methods: A total of 31 subjects (N = 24 77.4% women and N = 7 men 22.6%) aged 19 through 55 years (M = 31.32; SD = 8.50) participated in the study. The SCHNOS questionnaire was translated in accordance with international guidelines. The psychometric accuracy of translation was tested in native speakers of Polish. The authors measured the internal consistency, correlatability, and repeatability of the instrument to determine its validity. The data were subjected to statistical analysis.Results: The confirmatory factor analysis confirmed the two-factor structure of the scale. The satisfactory reliability amounted to 0.888 95% CI: 0.804–0.940 for the SCHNOS-O and 0.883 95% CI 0.795–0.937 for the SCHNOS-C scale. Differential accuracy was confirmed by AVE values of > 0.5 as well as by correlation of the results with the Rhinoplasty Outcome Evaluation (ROE) questionnaire scores.Conclusions: The SCHNOS questionnaire has been translated, adapted, and validated for use in the Polish-speaking population. The tool was found to be relevant and reliable.
