Validation of the Modified Rhinoplasty Assessment Scale (Photographic)

Objective: To validate the modified Rhinoplasty Assessment Scale (Photographic) (mRASP). Study Design: Retrospective cohort study. Methods: Study design—Photographs for 100 rhinoplasty patients from 2 facial plastic surgeons were compiled. Photos included 6 views. Each facial plastic surgeon reviewed all views. Nasal appearance was evaluated using the mRASP. Statistical analysis—A validation study was conducted, including descriptive statistics, reliability, and construct validity. Mean and standard deviations were used to describe the scores. Results: Eighty female (mean RASP score = 14.89, SD = 7.04) and 20 male (mean RASP score = 19.83, SD = 10.09) patients were included. The mean of the total score on the instrument was 15.88 (SD = 7.98). Cronbach’s alpha was .81, and inter-rater reliability measured as a Pearson product-moment correlation was .74. The CFA model fit the frontal view (χ2 = 32.47 (P = .04), CFI = .99, TLI = .99, RMSEA = .05, SRMR = .05), basal view (χ2 = 4.55 (P = .33), CFI = .98, TLI = .96, RMSEA = .03, SRMR = .23), and lateral view (χ2 = 39.52 (P = .40), CFI = 1.0, TLI = 1.0, RMSEA = .0, SRMR = .05) data well. Conclusion: The mRASP is a reliable instrument that can be used to assess nasal form via frontal, lateral, and basal photographs of patients. This provides facial plastic surgeons with a validated tool to evaluate rhinoplasty outcomes.
