lower eyelid reconstruction

The squat reduction surgery (lid-sharing technigue) is better for improving the appearance of the eyelids and the functional effects of the eyelids. The squat reconstruction is suitable for those with a lower iliac margin defect greater than 60% or all defects. The disadvantage of severe squat reconstruction is that it requires two steps. In the first step, 3 to 6 months after suturing the upper and lower jaws, the sutured gingival margin can be opened for the second operation. Treatment of diseases: congenital orbital defects Indication Suitable for squatting reconstruction. Surgical procedure Hughes palpebral transposition valvuloplasty 1. Cut the defect of the lower jaw and make the lower jaw two layers. The front layer is the skin and the posterior layer is the conjunctiva. The upper lip is also opened between the upper lip and sneaked to the iliac crest. The upper sac is the front and the back. The anterior layer includes the skin and the orbicularis oculi muscle. The posterior layer includes the tarsal plate and the conjunctiva. Corresponding to the ends of the lower jaw defect, the upper jaw is cut vertically to the dome. The margin tissue of the posterior layer of the upper eyelid is removed. 2. Place a make up in the conjunctival sac. The free edge of the lower layer of the upper and lower jaws is interrupted or continuously sutured, and the sides are sutured with the remaining slabs of the upper and lower jaws. At this time, part of the upper jaw plate tissue repaired the mandibular defect. The skin incision perpendicular to the gingival margin was made on both sides of the anterior humeral defect, and the subcutaneous tissue was separated to make it fully loose. The length of the incision was sufficient to cover the defect of the anterior tibiofibular defect. The lower edge of the migratory flap was sutured intermittently with the anterior border of the upper iliac crest. A triangular skin was removed from the distal end of the vertical incision on both sides of the migratory flap, and the skin wound edges on both sides were intermittently sutured. Hughes retains the superior temporal iliac crested palpebral reconstruction Trim the defect of the lower jaw. The upper eyelid was turned over, and the sacral plate was cut at a distance of 2 to 3 mm from the superior temporal margin, and the length was consistent with the defect of the lower jaw. The two ends of the slit are each made into a vertical incision of the seesaw to reach the upper humerus. The sacral separation between the tarsal plate and the orbicularis oculi muscle allows the tarsal conjunctival flap to move freely downward.
