Lower eyelid pedicled rotational flap reconstruction

Generally used to repair the defect of 1/2 long. The characteristics of the sacral pedicled rotator flap are that it retains the lower iliac artery arch, and the reconstructed part maintains the normal tissue of the eyelid layer and even retains the eyelashes. Treatment of diseases: congenital orbital defects Indication Generally used to repair the defect of 1/2 long. The characteristics of the sacral pedicled rotator flap are that it retains the lower iliac artery arch, and the reconstructed part maintains the normal tissue of the eyelid layer and even retains the eyelashes. Surgical procedure 1. Remove the upper tumor and repair the wound. Use a single hook to organize the ends of the defect, pull it toward the central part, restore the normal tension of the eyelid, and measure the actual defect range. Use a gentian violet to mark a and b on the skin of the lower jaw. Subtract the 1/4 inch length from the side of the marker point b and make another marker point h. 2. ah intercropping with a pedicle with a rotating flap. The ablation tissue at the a site is first cut vertically, and then the full-thickness incision of the eyelid is extended downward, the depth of which is consistent with the depth of the upper condyle defect. The slit is turned to h point. It can be cut to 3mm below the iliac crest, and the position of the iliac artery arch can be referred to at point a. In general, the iliac artery arch must be preserved at h point. Then, the skin is cut into the upper side of the iliac crest in the outer iliac crest, and the skin is incision to the lateral side of the eyebrow. The incision is curved to the temporal side and gradually lowers and ends before the hairline. Cut off the lower branch of the lateral malleolus ligament, sneak and sneak under the skin of the iliac crest, loosen all the pinching force, so that the sacral pedicled rotator flap and the temporal skin can freely move to the nasal side, and the sacral nasal side Layer stitching. 3. Rotate the pedicle with a pedicle for 180° rotation, and stratify the sutures on both sides of the defect at the corresponding defect of the upper palate. The incision of the pedicle of the rotating flap is sutured. The temporal side of the temporal skin incision was resected with an upward triangular skin and sutured intermittently. The temporal conjunctiva was inverted to repair the posterior wall of the lower temporal side.
