Obiective: To explore the method and clinical effect of epicanthal plasty. Methods: Transverse incision of epicanthus was applied on the horizontal line of the epicanthus to separate and release the orbicularis oculi muscle and the fibrous tissue and moderately remove the abnormal orbicularis oculi muscle. The redundant triangular flap under the incision was removed, and the superficial ligament of epicanthus was sutured and fixed to the dorsal nasal fascia with 1 stitch, so as to achieve correcting the epicanthus. Results: The epicanthus of the 121 patients was corrected after the surgery with their lacrimal caruncle exposed. The appearance of the endocanthion is pleasing, the skin of the endocanthion is smooth, the scar is invisible, and the oculi rimae is lengthened 1 to 3 mm. Conclusions The operation has achieved a satisfactory effect. Therefore, the horizontal transection to remove the triangular flap is applicable for most epicanthus due to its simplicity and practicality, as well as the invisible scar and simultaneous manipulation with other operations. These features might be significant for a wider clinical application.

Objective:To analyze the clinical effect of small incision approach conjoint fascial sheath (CFS) suspension in the treatment of congenital severe blepharoptosis, and to discuss its advantages and disadvantages compared with conventional CSF suspension.Methods:From February 2020 to August 2022, 42 cases of severe blepharoptosis in the Department of Burn, Plastic and Cosmetic Surgery, Shaanxi Provincial People's Hospital were divided into the observation group (23 cases, 39 eyes) and the control group (19 cases, 37 eyes). The observation group was treated with small incision CFS suspension surgery, while the control group was treated with conventional CFS suspension surgery. The correction effect, complications, recovery time and other conditions between the two groups at different times after surgery were compared.Results:During postoperative follow-up at 1 week, 1 month, 3 months, and 6 months, there was no significant difference in the corrective effect between the two surgical methods at each time point (all P>0.05). The incidence of complications in the observation group at each time point that was 26.3%, 15.7%, 10.5%, and 5.2%, respectively, while the incidence of complications in the control group was 60.0%, 20.0%, 14.2%, and 8.6%, with statistical differences in the first week after surgery (χ 2=8.74, P=0.011). The average postoperative swelling time in the observation group was 4.2 days, which was less than 5.8 days in the control group. During a 6-month follow-up, it was found that there was a decrease in scar hyperplasia in the observation group of 9.1% (2/22) compared to the control group of 16.7% (3/18) (χ 2=0.023, P=0.878). The difference was of no statistical significance. Conclusions:CFS suspension with small incision in the treatment of moderate and severe blepharoptosis has the advantages of ideal correction effect, small damage range, and few postoperative complications, but the operation area is small, the operation is difficult, and the surgeon has higher requirements.
