Superior or inferior rectus surgery

Treating diseases: strabismus Indication Upper or lower rectus surgery is applied to: 1. The superior rectus muscle migration is suitable for upper strabismus with strong rectus muscles or weak inferior rectus muscles or weak inferior oblique muscles. 2. The lower rectus muscle migration is suitable for the lower strabismus with weak rectus muscle or weak upper rectus muscle or weak upper oblique muscle. Contraindications 1. The upper strabismus produced by the weak oblique muscle in the eye. At this time, it should be done to strengthen the orthopedic muscle of the eye or weaken the inferior oblique muscle or the subcutaneous rectus muscle migration, and not to treat the ocular straight muscle migration. 2. The lower strabismus caused by the weak inferior oblique muscle should be treated with inferior oblique muscle reinforcement or weakening of the superior oblique muscle or weakening of the superior ocular rectus muscle. Surgical procedure For example, the above straight muscle migration is as follows: 1. Make a limbus trapezoidal conjunctival incision and separate the connection between the bulbar conjunctiva and the fascia. 2. Cut a small hole in the fascia on both sides of the superior rectus adhesion point, vertically separate to the sclera and fully expose, and separate the sclera from the fascia along the bilateral rectus muscle. 3. From one side of the small hole into the strabismus hook, with the sclera sliding under the superior rectus muscle, to reach the opposite side of the hole. If the top of the squint hook is blocked by the fascia, it is separated. So from left to right, from right to left, repeated 2 to 3 times, can hook the entire superior rectus muscle. 4. Separate the fascia and intermuscular membrane along the two sides of the superior rectus muscle to fully expose the superior rectus muscle. 5. On both sides of the upper rectus muscle attachment point 1.5mm, use 6-0 absorbable suture or nylon thread as the collar preset suture, and cut the upper rectus muscle from the attachment point. 6. Measure the distance after migration on the sclera and fix the preset suture to the new attachment point. 7. Observe the eye position and eye muscle movements and adjust if necessary. 8. Stitch the conjunctiva. complication Postoperative cleft palate increased.
