partial resection of inferior oblique muscle

The inferior oblique muscle stenosis and partial inferior oblique muscle surgery are suitable for patients with acute orthopedic or oblique superior or oblique upper rectus muscles and V-shaped strabismus with oblique oblique muscles. Upper strabismus also occurs if the inferior rectus muscle is weak or the superior rectus muscle is strong or the other inferior oblique muscle is weak. At this time, the ocular rectus muscle should be applied or the inferior rectus muscle should be strengthened or the other inferior oblique muscle strengthening. Treatment of diseases: paralytic strabismus common strabismus Indication Suitable for different types of congenital paralytic vertical strabismus. Surgical procedure 1. In the inferior quadrant of the eyeball, 9mm from the limbus, a conjunctival incision parallel to the limbus, 8mm long, penetrating the conjunctiva, eyeball fascia and intermuscular membrane, straight to the sclera, the incision must be in front of the infraorbital fat pad. 2. The head of the fly is inserted into the incision, closely attached to the sclera, and the filamentary relationship between the sclera and the inferior oblique plane is separated. 3. Hook the lower oblique muscle under direct vision. First, extend the two large squint hooks to the attachment points of the lateral rectus and inferior rectus muscles, and then hook the posterior lip of the conjunctival fascia incision with another small hook. Deep in the incision, at the junction of the sclera and the posterior tenon membrane, the leading edge of the inferior oblique muscle can be seen. 4. Use a small squint hook to lift the leading edge of the inferior oblique muscle. Note that only the front edge of the muscle is hooked to avoid penetrating the intermuscular membrane (posttenon membrane). Causes unnecessary fat loss, bleeding and postoperative traction adhesion. 5. Use a scissors or scalpel to separate the tip of the small squint hook to expose the squint hook. 6. Use two large squint hooks instead of small squint hooks to separate the fascial layer tissue associated with the inferior oblique muscles, revealing the 5-8 mm long inferior oblique muscles, and withdrawing the lateral rectus muscle and the inferior rectus muscle. Strabismus hook at the place. 7. Use two hemostats to separate the distance of 6 ~ 8mm, and clamp the musculature of the inferior oblique muscle. 8. Use a pair of scissors or a scalpel to remove the 5 mm long oblique muscle sandwiched between the two hemostats. After cauterizing the muscle end with an electric iron, remove the hemostat and retract the inferior oblique muscle. 9. Intermittent or continuous suture of the conjunctival incision.
