superior oblique tendonectomy

Ankle resection, scapular or posterior migration can be used to effectively attenuate the superior oblique muscle function. The tendon sheath and the attached fascia should be destroyed as little as possible during surgery. Treatment of diseases: upper oblique palsy, upper oblique oblique tendon sheath syndrome Indication Apply to any obvious secondary or primary oblique hyperthyroidism. Contraindications 1. Suffering from ocular strabismus in the lower part of the lower rectus muscle or upper rectus muscle or weak in the other side of the oblique muscle. 2. Unexplained upper oblique palsy. Surgical procedure 1. Starting from the nasal side of the superior rectus adhesion point, extending to the nasal side, making a conjunctival incision parallel to the limbus, about 8 mm long, through the conjunctiva, eyeball fascia and intermuscular membrane, straight to the sclera. 2. Hook the attachment points of the superior rectus muscle and the medial rectus muscle with two squint hooks, and then use the third squint hook to hook the conjunctiva, the eyeball fascia and the intermuscular membrane at the posterior edge of the incision. Pull the three squint hooks outward to form an equal triangle. 3. A white band, the superior oblique muscle tendon in the musculature, is visible deep in the incision. Here, the superior oblique muscle tendon is about 3 mm wide, and the strabismus hook is inserted deep into the incision, and the superior oblique muscle tendon and a small amount of attached ocular fascia and intermuscular membrane are hooked. 4. Cut the tissue on the tip of the squint hook so that the hook protrudes from the superior oblique muscle. The tendon sheath is cut along the long axis of the tendon, and only a small hook is used to hook the tendon and cut it.
