Validation of the Rhinoplasty Outcomes Evaluation (ROE) questionnaire adapted to Brazilian Portuguese

Purpose the aim of this study was to validate the Rhinoplasty Outcomes Evaluation (ROE) questionnaire adapted to the Brazilian Portuguese.A prospective study was conducted with ROE administration to 56 patients submitted to rhinoplasty (preoperatively, and then 15-day and 90-day postoperatively) and 100 volunteers without the need or desire of cosmetic or functional nasal surgery. Reliability (internal consistency and test-retest reproducibility), validity, responsiveness and clinical interpretability were assessed.Rhinoplasty patients' mean preoperative score was 7.14, 15 days post-op 17.73 and 90 days post-op 20.50, while controls presented 17.94 points (p < 0.0001), showing the questionnaire's validity and responsiveness. Internal consistency was 0.86. Inter- and intra-examiner test-retest reproducibility was 0.90 and 0.94, respectively. the effect size caused by the surgery was considered large (15 days post-op compared to the preoperative score: effect size = 3.22; 90 days post-op compared to preoperative score: effect size = 4.06). the minimally important difference was 8.67 points, so changes smaller than 9 points in ROE might not be perceived by the patient as an improvement or worsening.The Brazilian Portuguese version of ROE is a valid instrument to assess results in rhinoplasty patients.UNIFESP EPM, Dept Otorhinolaryngol & Head & Neck Surg, São Paulo, BrazilUNIFESP EPM, Dept Otorhinolaryngol & Head & Neck Surg, São Paulo, BrazilWeb of Scienc
