PURPOSE: The aim of this study was to validate the Rhinoplasty Outcomes Evaluation (ROE) questionnaire adapted to the Brazilian Portuguese.; METHOD: 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.; RESULTS: 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.; CONCLUSION: The Brazilian Portuguese version of ROE is a valid instrument to assess results in rhinoplasty patients.
