Discrepancy of the subjective perception of the nasal appearance between independent individuals and patients undergoing functional rhinoplasty (fRPL).

[PURPOSE] Satisfaction with the nasal appearance is a crucial outcome parameter in functional rhinoplasty (fRPL). The visual analogue scale is a suitable instrument not only for the preoperative patient assessment, but also as a patient-reported outcome measure in fRPL. In this study, we analyzed whether a high discrepancy in the preoperative subjective perception of the nasal appearance between patients and other individuals predicts a lower level of satisfaction with the postoperative result and hence a worse outcome of fRPL.

[METHODS] Standardized facial pictures of patients (n = 80) who underwent fRPL were taken preoperatively, 3 and 12 months postoperatively. In addition, patients were asked to complete the German version of the Utrecht Outcome Assessment Questionnaire in Aesthetic Rhinoplasty (D-OAR). The standardized facial pictures of the patients were presented to surgeons as well as to examiners without a medical background, and they were asked to evaluate the patients' nasal appearance using the visual analogue scale.

[RESULTS] The external evaluation of patient's nasal appearance was 1.7 points higher in median than the patient's subjective perception (range -5.7-7.00). A large discrepancy between self- and external estimation significantly correlates with higher D-OAR values (r = 0.539, p < 0.001). Patients with high scores in the D-OAR trick questions, indicating a body dysmorphic disorder, show a significant larger discrepancy between the external- and the self-assessment (2.8 ± 0.5 vs. 1.4 ± 0.3, mean ± SEM, p = 0.017).

[CONCLUSIONS] Large discrepancies between the self and external assessment of the nasal appearance are associated with a high-perceived influence of the appearance of the nose on the quality of life in patients undergoing functional rhinoplasty. That might be an indicator for unrealistic expectations concerning the postoperative outcome. Knowledge about this factor helps to identify the need for intensive discussion about possibilities and limitations of the planned procedure to avoid postoperative dissatisfaction.
