Inner and outer canthoplasty, commonly known as eye opening, is a surgical procedure to correct and enlarge the inner and outer corners of the eye, respectively, in order to remove the inner canthus and lengthen the horizontal length of the eye fissure, so as to achieve the effect of enlarging the eyes. Some people will have hyperplasia after eye opening, especially the inner corner of the eye is more likely to appear, generally based on the patient’s symptoms can be clear. Eye opening hyperplasia refers to proliferative scarring, which usually occurs within 6 months after the surgical stitches are removed. If after the removal of stitches, there is obvious scar reaction at the surgical site, the scar protrudes from the skin, hardens locally, and the surface of the scar is flushed red, accompanied by slight itchiness and pain, and in severe cases, local contracture and deformation will occur, then it indicates that there is keloid hyperplasia at the corner of the eye. Keloid scarring after eye surgery can be improved slowly over time, and in the early postoperative period, it is necessary to prevent keloid scarring by using silicone drugs to promote the recovery of keloid scarring. If there is serious scar proliferation, local tissue deformation, can consider local injection of hormone control. It is recommended that patients must be patient in daily care, appropriate local hot compresses; diet should avoid spicy and stimulating food.
