chi-squared test. A p-value < 0.05 was considered statistically significant. Patients’ demographics and post-operative measures including esthetical outcome, MRD1 and satisfactory outcomes were shown (Table 1). In terms of esthetic outcomes, all patients had an obvious crease without multiple folds, no disappear-ance of the fold and a bilateral symmetric eyelid except 1 patient presented with disappearance of fold by 1 month postoperatively, 6 patients presented with bilateral asymmetrical lid folds by 2 months postoperatively. The patients who presented with disappearance of fold and bilateral asymmetrical lid folds were performed for revisional surgery by the end of 6 months. In terms of functional outcomes, the MRD1 was measured and calculated only for the 60 patients who attended a follow-up visit in the clinic after 1 month of surgery. Among them (n=60; 7 men, 53 Figure 3　Measurement of symmetric lid folds by adjusting the direction of eyelash lines (a) Preoperative appearance of eyelash direction of right side of the eyelid.

A representative case was shown (Figure 5). Patient satisfaction was evaluated after postoper-ative months 1, 2, 3, and 6 in all patients. Patients’ satisfaction changed with the passage of time. After 1 month, 149 patients (49 %) were very satisfied with the result, 197 patients (65 %) were very satisfied with the result at 2 month, 218 patients (72 %) were very satisfied with the result at 3 month and 259 patients (85 %) at 6 months. Two patients out of 304 patients (0.66 %) were not satis-fied with the result by the end of 6 months (Figure 6). It was found that the differences in preference between small and large lid fold size among the ethnic groups were significantly different by the end of 6 months (Table 2).
