Objective: To evaluate the effect of continuous embedding on the improvement of mild epicanthus by studying the change of intercanthal distance and inner canthus angle in patients perioperatively. Methods: In this study, 34 patients with single eyelid and mild epicanthus were analyzed retrospectively. Procedure included small incisions combined with continuous embedding double eyelid surgery. The photo of eyes was taken in the front position preoperatively and postoperatively. Before operation, 3-months, 6 months-after operation, intercanthal distance and inner canthal angle of both eyes were measured by Photoshop CS6. The iris diameter scale was used to measure intercanthal distance. Results: Preoperative intercanthal distance (PRICD) values were 65.96±4.94 (iris diameter scale), 3-month-postoperative intercanthal distance (3POICD) values were 63.43±5.04 (iris diameter scale), and 6-month-postoperative intercanthal distance (6POICD) values were 63.82±5.02 (iris diameter distance). Preoperative inner-canthal angle of the left eye (PRCAL) values were (47.51±4.28)°, preoperative inner-canthal angle of the right eye (PRCAR) values were (47.30±4.55)°, 3-month-preoperative inner-canthal angle of the left eye (3POCAL) values were (49.53±5.15)°. 3-month-preoperative inner-canthal angle of the right eye (3POCAR) values were (49.24±4.86)°, 6 month-postperative inner-canthal angle of the left eye (6POCAL) values were (49.48±4.74)°, and 6 month-postperative inner-canthal angle of the right eye (6POCAR) values were (48.99±4.55)°. The difference between PRICD and 3POICD, PRICD and 6POICD, PRCAL and 3POCAL, PRCAL and 6POCAL, PRCAR and 3POCAR, PRCAR and 6POCAR were statistically significant (t=6.432, 6.307, -2.882, -3.188, -2.516, -2.248, P<0.05). The difference between 6POICD and 3POICD was statistically significant (t=4.047, P<0.05); moreover, the mean value of 6POICD was larger than the mean value of 3POICD. There was no significant difference between 6POCAL and 3POCAL, and 6POCAR and 3POCAR (t=0.352, P>0.05). Conclusions According to the result of the study, the continuous embedding method has a certain effect on shortening the intercanthal distance and changing the inner canthal angle. It is inferred that the continuous embedding method has a certain effect on the improvement of mild epicanthus.
