Small incision double eyelid surgery is based on the incision method, combined with the characteristics of the buried wire method, using a small incision in the outer canthus. It is suitable for young single-lidded patients with mild or moderate tissue hypertrophy of the upper eyelid with skin laxity. For single-lidded patients who need to remove the skin and have severe tissue hypertrophy of the upper eyelid, the incisional method of double eyelidoplasty is still required. What are the surgical features of the small incision double eyelid: 1. The surgery creates a lasting double eyelid fold line while avoiding incisional scarring. 2. Because the surgery uses small incisions in the outer canthus, it is difficult to be detected after healing, while the upper eyelid skin is not cut in its entirety, which does not affect the local tissue fluid reflux, so the edema is not obvious after surgery and can return to normal in 3 days. 3. The small incision double eyelid surgery removes the excess muscle and fat in front of the lid, resulting in a natural, smooth and long-lasting double eyelid. 2 to 3 days after small incision double eyelid surgery, the redness and swelling of the suture site is obvious. This situation suggests a high possibility of infection and must be seen early to open up the drainage and remove the sutures in time, otherwise the infection will not be easily controlled. Also use topical antibiotic eye medication, oral or intramuscular antibiotics. If the skin around the eye of the needle is red and slightly hard. This is a normal reaction and can be done without special treatment. 1 week or more after small incision double eyelid surgery, there are always hard knots on the skin of the suture site, which is mostly seen in the case of incomplete embedding of the knots and stimulation of the skin tissue due to chronic inflammatory reaction. The treatment can be local physical therapy, local external application of some de-inflammatory pine ointment and hot compress, etc., generally can be self-absorption without leaving sequelae. If the result is not good, then removal of the sutures can be considered.
