自1979年,我们应用上、下直肌移位方法,治疗外直肌全麻痹患者7例,收到满意效果,介绍如下。球结膜下浸润麻痹后,在内直肌附着处作一12mm 左右的球结膜切口。分离内直肌。予置缝线后,将内直肌从巩膜附着处剪下,平行后移6—8mm,固定在浅层巩膜。暂以活结扎牢,以便术中修正手术量。若患眼努力外转仍有10°的内斜可退后6mm,若有20°内科,须退后8mm。在上直肌和外直肌的附着处之间剪开结膜和眼球筋膜,暴露巩膜和上直肌。将上直肌肌腹从中间分开。顺着肌纤维方向,前后钝性分离。将上直肌自巩膜附着处到赤道部以后分成长约25mm 左右的两束。在外侧束的近附着处缝予置线。于附着处剪断外侧肌束。用双针分别引向外直肌附着处。从附着处上
Since 1979, we applied the upper and lower rectus muscle shift method, the treatment of patients with total rectus abdominis paralysis in 7 cases, received satisfactory results, described below. Subconjunctival infiltration paralysis, the rectus abdominis attached to a 12mm ball conjunctival incision. Detach the inner rectus muscle. After the suture is set, the medial rectus muscle is cut off from the sclera attachment and then moved 6-8 mm in parallel to fix the superficial sclera. Temporarily to live firmly jail, so that surgery to correct the amount of surgery. If the outer eye efforts still have 10 ° of retreat retreat 6mm, if 20 ° internal medicine, to retreat 8mm. The conjunctiva and the eyeball were cut between the upper rectus and the attachment of the rectus abdominis to expose the sclera and upper rectus. The upper rectus abdominis separated from the middle. Along the muscle fiber direction, before and after blunt separation. The upper rectus muscle from the adherent to the equator to the equinox divided into about two about 25mm. In the outer side of the beam near the Department of sewing thread placement. Shear the lateral muscle bundle at the attachment. With two-pin respectively lead to the rectus abdominis attachment. From the attachment
