Abstract

The outcome of aesthetic rhinoplasty is determined by the patient’s subjective satisfaction with the nasal appearance which is difficult to assess. The Utrecht Questionnaire for Outcome Assessment in Aesthetic Rhinoplasty (OAR) is a brief and reliable instrument to assess the influence of the subjective nasal appearance on quality of life in patients undergoing aesthetic rhinoplasty. Preoperative application of this questionnaire reveals important aspects and possible disturbances of the body image which could be negative predictors concerning the result. On the other hand, it represents an appropriate tool to assess the postoperative outcome. The aim of this study was to determine the validity, reliability and responsiveness of the adapted German version of the OAR (D-OAR). The adaption of the OAR to German language was performed by a forward and backward translation process. Patients undergoing rhinoplasty were asked to complete the D-OAR preoperatively, 1, 3 and 12 months after procedure and healthy volunteers without any nasal complaints served as controls to test validity, reliability and responsiveness. An excellent internal consistency, a good test–retest reliability and good inter-item and item-total correlations demonstrated a good reliability of the D-OAR. The convincing validity of the adapted version was proven by an excellent discriminant and a sufficient content validity. Significant differences between pre- and postoperative D-OAR scores revealed a good responsiveness of the instrument. Hence, with a sufficient validity, reliability and sensitivity to changes, the D-OAR is a short and helpful instrument to assess the subjective perception of the nasal appearance in German patients.
