动眼神经麻痹时因外直肌和上斜肌的作用而使眼球呈向下、向外的固视状态。既往曾行多种手术作眼位矫正,但均存在不同程度的缺陷。Scott手术也不够理想。作者对该术加以改良共治疗7例单眼动眼神经麻痹,4例为先天性,3例为外伤性。有2例曾行水平直肌手术失败,另2例有动眼神经迷路植入。术前检查见上睑下垂,患眼内直肌完全麻痹,上斜肌及外直肌功能良好,牵拉试验正常。手术在全麻下进行。切开角巩膜缘球结膜和筋膜囊,暴露上斜肌,内直肌及上直肌,以6—OTycron线穿过上斜肌肌腱,结扎、切断,
Oculomotor nerve paralysis due to the role of the external rectus and oblique muscles so that the eye was downward, outward fixation state. Past surgery has been a variety of eye correction, but there are varying degrees of defects. Scott surgery is not ideal. The authors modified this technique to treat 7 patients with monocular oculomotor nerve palsy, 4 were congenital and 3 were traumatic. There were 2 cases of horizontal rectus muscle surgery failed, and the other 2 cases of oculomotor nerve implanted. Preoperative examination, see ptosis, intraocular rectus muscle completely paralyzed, upper oblique and lateral rectus function well, traction test is normal. Surgery under general anesthesia. Incision angle scleal bulb conjunctiva and fascia sac, exposed upper oblique, medial rectus and superior rectus, 6-OTycron line through the upper oblique tendon ligature, cut off,
