Wedge-shaped tarsal transition flap at the center of the eyelid

The wedge-shaped palpebral transitional valvuloplasty in the central part of the eyelid is a kind of ocular cleavage. For patients with large demand for ocular rupture, the cleft palate can be permanently enlarged after surgery. Treatment of diseases: ophthalmologic myasthenia gravis Indication Patients with small eye cracks. Preoperative preparation 1 Check the patient's operation of the eye according to the medical record, pay attention to the left and right eyes, upper and lower jaws, and surgical methods. 2 patients on the supine surgery table. 3 When the surgical eye needs to be surface anesthetized, 0.5% tetracaine (dicaine) can be dripped, 1 drop each time, once every 2-3 minutes, for a total of 3 times. The lacrimal passage exploration technique uses a small cotton swab to lick 0.5% tetracaine and then clips it into the inner corner, and can take a seat without disinfection. 4 According to the type of surgery, the following methods can be used to clean and disinfect: clean the eyelid skin with soapy water, rinse the conjunctival sac with 0.02% benzalkonium bromide (new chlorhexidine) solution or 1:5000 chlorhexidine solution, and then disinfect with 75% ethanol. Area skin, and finally cover the surgical towel or hole towel. Surgical procedure 1. Measurements require a range of extended split lengths. The upper marginal layer is opened between the layers, and the upper part of the upper tear is cut to the outer ankle, and the depth reaches the upper edge of the sac. The eyelid hook flips the upper jaw and makes a wedge-shaped incision from the gingival margin to the iliac crest in the central part of the upper palate. The entire fascia is cut off. The angle between the incisions is determined by the length of the enlarged cleft palate. The angle is large and the cleft palate is enlarged. The range is large. On the contrary, if the angle is small, the range of cracking will become smaller, and most of them are 60°. 2. The wedge-shaped flap of the seesaw is moved in the direction of the gingival margin, and the original slabs are moved to the sides to expand the cleft palate to the preoperative design requirements. If the wedge-shaped flap of the seesaw is moved toward the gingival margin, there is resistance on the outer side of the eyelid, or when the curvature of the sacral margin is not ideal, the upper branch of the lateral ligament can be cut. 3. Buried suture on the orbicularis muscle surface of the tarsal plate. 2mm on the gingival margin for the full-thickness suture of the eyelids, through the skin, the pad is ligated with a rubber sheet. It can also be used as an intermittent suture of the iliac crest, paying attention to the knot of the knot outside the skin. Finally, the excess tarsal tissue protruding beyond the rim of the iliac crest is removed. complication Blood may be emitted during the operation and can be avoided by taking hemostasis measures. Postoperative levator palpebral weakness may occur and may be repaired after surgery.
