conjunctival defect plasty

The conjunctival tissue is rich in blood vessels, especially the conjunctiva is loosely combined with the underlying sclera. It is easy to move and separate during surgery. Therefore, various forms of conjunctival flaps are often used to repair defects after benign tumor resection. Such as conjunctival hemangioma, papilloma, pigmented nevus and so on. Due to the different extent of conjunctival defect, the repair method is different. Treating diseases: viral conjunctivitis Indication Conjunctival defect angioplasty is applicable to: 1. Repair of various benign tumors and defects after resection of pigmented nevus. 2. The formation of conjunctival defects after mild symblepharon adhesion is eliminated. Surgical procedure Direct suture (1) Under local anesthesia, if the conjunctival defect area is small, the wound edge can be sneaked apart, intermittently or continuously sutured. (2) The conjunctival defect area is large, and the wound edge is appropriately extended into a triangle, and the base is parallel to the cornea, and the incision is extended to both sides. (3) Separation under the conjunctiva on both sides to make two triangular conjunctival flaps. (4) The conjunctival flaps are aligned with each other and sutured intermittently. 2. Conjunctival flap transposition (1) Under local anesthesia, the upper and lower ends of the defect surface are pedicled, and a conjunctival flap is taken on the upper and lower sides of the cornea, and separated to dissociate. (2) Transfer the upper and lower conjunctiva flaps to the inner and outer halves of the defect surface, and suture intermittently. The upper and lower conjunctival flaps were sneaked and sewn. 3. With pedicled conjunctival flap transfer, the upper or lower conjunctival defect is difficult to suture directly, and the corresponding pedicled conjunctival flap can be taken, that is, the lower defect is taken, and the upper bulbar conjunctiva is taken, and vice versa. The donor area is continuously or intermittently sutured.
