lateral canthal suture palpebral fissure shortening

Opening the outer corner of the eye is a big open surgery. The opening of the outer corner of the eye is mainly performed under local anesthesia, and the incision is determined according to the degree of enlargement required for the splitting. Opening the outer corner of the eye can make the eye banner longer by 2-3mm, making the eyes longer, bigger, and more radiant. This technique is suitable for severe internal ecdysis or associated with deformed adjacent parts, as well as congenital eyes that are small and eager to change. Treatment of diseases: internal suede Indication 1. Paralytic valgus valgus. 2. The cleft palate is too long, or the size of the two eyes is splitting, and one of the eyes is too long. Preoperative preparation The cleft palate shortening is considered when the paralytic valgus valgus is stable for at least one year, or when the corneal effusion is exposed to severe keratitis. If the bell phenomenon is normal when the cleft palate is shortened, the shortening range can be shorter, and if there is no bell phenomenon, the cleft palate shortening range should be larger. Surgical procedure External iliac crest suture First, the range of cleft palate that needs to be shortened is measured, and the cleft palate is marked. The epithelial tissue of the superior and inferior temporal margins within this range is excised. If the purpose of the operation is to temporarily shorten the cleft palate, it can be used as a palpebral interlaminar cleft, and the posterior epithelium of the iliac crest is removed to preserve the eyelashes, otherwise it can be removed at the same time. The upper and lower iliac crests are directly sutured, and the sutures are passed through the tarsal tissue to make the adhesions firmer. They can also be separated between the layers and buried between the upper and lower slabs. Interspersed skin intermittently. Fuch external iliac crest suture 1. Use a pair of tweezers to clamp the outer and outer iliac crests, and estimate the width of the cleft that needs to be shortened and mark it. Within the marking range, the layers are split open to the outer ankle, and the depth is up to the upper or lower edge of the crucible. The epithelial tissue of the anterior lip of the temporal margin was removed. 2. Make a vertical skin incision at the inferior temporal margin mark and sneak away to make a triangular flap. A similar triangular flap is removed within the corresponding upper temporal margin marker. 3. Pull the triangular flap of the lower jaw upwards to the defect of the anterior layer of the anterior layer, and fix it as a sacral suture. The double-needle suture is used to insert the needle from the posterior conjunctiva 3mm from the iliac crest. And the lower triangular flap, which is worn out by the skin, and the partial pad is ligated with a rubber sheet. The skin wound edge is sutured intermittently. Elschnig sacral suture 1. First estimate the length of the split that needs to be shortened and mark it on the rim. At the mark, the upper and lower ridges are opened between the layers to the outer ridge, deep to the upper or lower edge of the raft. The rim margin is used as a vertical incision for the upper and lower jaws. The triangular tarsal conjunctival flap of the upper iliac crest was removed. The epithelial tissue of the posterior lip of the condylar flap of the iliac crest of the lower ankle was removed. 2. Pull the conjunctival flap of the lower tarsal plate upward, cover the defect of the posterior iliac crest, and make the suture fixation, that is, the conjunctiva of the conjunctiva of the lower jaw is inserted into the conjunctiva, passing through the tarsal plate and the upper condyle defect. The orbicularis muscle in the wound surface is worn out by the skin surface, and the pad is ligated with a rubber sheet. The skin is sutured intermittently. Wheeler sacral suture 1. Estimate the extent of shortening of the split according to the surgical requirements. Open the upper and lower edges of the rim, and reach the upper or lower edge of the right. A vertical incision was made at the inferior temporal margin mark, and the sacral conjunctiva and the epithelial tissue of the temporal margin were removed to make it a triangular sacral flap. 2. Insert the sacral flap into the iliac crest of the upper jaw and make a full-thickness suture fixation, that is, the suture is penetrated by the palpebral conjunctiva of the upper palate, passing through the upper iliac crest The tarsal flap is worn by the upper eyelid rim muscle and the skin surface, and is ligated with a rubber sheet. 3. Intermittent suture of the upper and lower iliac margins.
