Translation, cross-cultural adaptation, and validation of the functional rhinoplasty outcome inventory-17 (FROI-17) in Turkish-speaking patients: a prospective validation study

BACKGROUND: Functional rhinoplasty aims to improve nasal airflow and patient satisfaction, yet standardized assessment tools for outcome evaluation in Turkish-speaking patients are lacking. AIMS/OBJECTIVES: To translate, culturally adapt, and validate the Functional Rhinoplasty Outcome Inventory-17 (FROI-17) for use in Turkish-speaking patients undergoing functional septorhinoplasty. MATERIAL AND METHODS: forward-backward translation, expert review, and pilot testing. Patients completed the Turkish version of the FROI-17 (FROI-17-TR) and SNOT-22 preoperatively and at the third postoperative month. Internal consistency, inter- and intra-rater reliability, convergent validity, and responsiveness were evaluated. RESULTS: < 0.001). Both FROI-17-TR and SNOT-22 scores decreased significantly following surgery, reflecting clinical improvement. CONCLUSIONS AND SIGNIFICANCE: The findings of this study suggest that the FROI-17-TR appears to be a valid, reliable, and responsive patient-reported outcome measure for Turkish-speaking populations. Its implementation may enhance standardized patient-centered outcome assessment in both clinical practice and research.
