tistically significant differences between skin types when comparing preoperative and 6-month postoperative scores or 6- and 12-month postoperative scores ( P > .05) (Table 2). The patients in this study showed no statistically signifi- cant differences according to skin type inROE scores at the pre- operative ( P = .60) or 6-month postoperative ( P = .07) evalu- ations. PostoperativeROEscores amongpatientswith thick skin types were noticeably lower than those of patients with nor- mal skin types, although the differences between skin types in 12-month postoperative ROE scoreswas not statistically sig- nificant ( P = .83) (Table 2 and Figure 3 ). Among all patients, mean (SD) ROE scores were 7.03 (3.70) at thepreoperative evaluation, 21.06 (3.82) at the6-monthpost- operative evaluation, and 23.12 (2.09) at the 12-month post- operative evaluation. The mean increases in scores from the preoperative to 6-month postoperative (14.03 [5.12]), preop-

Among patients with a thin skin type, mean (SD) NOSE scores decreased significantly from the preoperative to 6-month postoperative (−4.00 [4.88]; P = .008), preoperative to 12-month postoperative (−6.47 [5.07]; P < .01), and 6- to 12- month postoperative (−2.47 [2.21]; P < .01) evaluations ( Figure 2 ). Amongpatientswithanormal skin type,meanNOSE scores decreased significantly from the preoperative to 6-month postoperative (−4.45 [6.32]; P = .001), the preopera- tive to 12-month postoperative (−8.13 [4.48]; P < .01), and the 6- to 12-month postoperative (−3.68 [4.28]; P < .01) evalua- tions. Patients with a thick skin type also showed statistically significant decreases inNOSE scores from the preoperative to the 6-month postoperative (−2.84 [5.73]; P = .04), preopera- tive to the 12-month postoperative (−4.80 [5.22]; P < .01), and 6- to 12-month postoperative (−1.96 [2.16]; P < .01) evalua- tions.
