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

Résumé fourni par la source

Functional rhinoplasty aims to improve nasal airflow and patient satisfaction, yet standardized assessment tools for outcome evaluation in Turkish-speaking patients are lacking. To translate, culturally adapt, and validate the Functional Rhinoplasty Outcome Inventory-17 (FROI-17) for use in Turkish-speaking patients undergoing functional septorhinoplasty. A prospective observational study was conducted in 35 adult patients scheduled for functional septorhinoplasty. Translation and cultural adaptation followed established guidelines via 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. The FROI-17-TR demonstrated high internal consistency (Cronbach’s α = 0.828). Reliability analysis showed excellent agreement (ICC > 0.95 for inter-rater and intra-rater assessments, p < 0.001). Convergent validity with SNOT-22 was strong both preoperatively (ρ = 0.847) and postoperatively (ρ = 0.864) (p < 0.001). Both FROI-17-TR and SNOT-22 scores decreased significantly following surgery, reflecting clinical improvement. 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.
