ABSTRACT
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.
