cicatricial ectropion repair

After the eyelids are everted, the conjunctiva is congested, hypertrophic or keratinized. The valgus valgus can expose the cornea, form corneal ulcers or white spots, and even cause blindness, so it should be corrected in time. There are many ways to correct the valgus valgus, and it needs to be selected according to the different degrees of valgus. Eversion caused by mild linear scars in the lower jaw; shape correction can be performed with vy or z. A large area of scar valgus is treated with skin grafting. Severe eversion, tissue destruction is very deep, only those with normal conjunctiva, the upper palate is often repaired with ankle flap, and the lower jaw is often repaired with ankle flap. A mild valgus valgus can also be repaired with a flap of the upper eyelid. Treating diseases: valgus Indication Eversion caused by mild linear scars in the jaw. Preoperative preparation If the conjunctiva has obvious inflammation and secretions are more, it can be applied or treated with antibiotic eye ointment for several days, and the operation will be performed after the inflammation subsides or is alleviated. Patients with diarrhea and lacrimal sacitis should be treated first. Surgical procedure The above valgus is an example. 1. Incision: A cut parallel to the rim of the iliac crest at a distance of 2 to 3 mm from the iliac crest. The ends of the incision slightly exceed the inner and outer crotch. 2. Separation and correction: Pull the upper and lower wound edges with a pointed hook and carefully separate them to reset the eversion of the eyelids. Generally, the depth of the scar is on the surface of the orbicularis muscle, which can be separated along the surface of the rim muscle to avoid too deep. 3. Transplantation of the skin: a full-thick or medium-thickness skin graft was taken from the inner side of the upper arm or the supraclavicular fossa to the wound surface, and the skin was sutured. 4. Stitching the iliac margin: 4×2mm length-shaped tissue was removed at the medial and inner 1/3 junction of the upper and lower temporal margins and at the border of the middle and outer 1/3, respectively, forming upper and lower relatives. The wound surface is sutured between the iliac crests, causing adhesion of the eyelids. 5. Compression dressing: After the graft skin is fixed by wrapping, the blood clotting in the conjunctival sac is rinsed from the corner of the eye with a syringe containing saline, and an antibiotic eye ointment is applied to the ocular fissure, and the dressing is pressed and wrapped. The following valgus is an example: the local scar is first cut open or removed, so that the upper jaw returns to the normal position. Then, the corresponding rotating flap is designed (the length and width of the flap can reach 3 to 4:1, and tissue necrosis does not occur). The donor site can be used for sneak separation and stitching. When repaired with a flap, it is generally not necessary to perform a marginal adhesion.
