動眼神経麻痺の手術

Superior oblique transposition surgery to paralytic exotropia associated with oculomotor nerve palsy

（1）動眼神経麻痺による麻痺性外斜視12例に対して，上斜筋移動法と外直筋後転法を併用し，好結果を得た。

（2）上斜筋移動法は滑車および内直筋を操作しなくても効果がある。

（3）上斜筋移動法による術後上斜視の予防に，上直筋後転を併用する手術力法を紹介した。

（4）上斜筋移動法は内直筋完全麻痺に適応となる。

We surgically corrected paralytic exotropia due to oculomotor nerve palsy in 12 cases by means of transposition of the superior oblique tendon above the site of insertion of the medial rectus and by re-cession of the lateral rectus. Severance of the troch-lea and resection of the medial rectus were avoided in our procedure. Satisfactory reculsts were ob-tained in all the treated cases. The possible hyper-tropia due to transposition could be successfully avoided by recession of the superior rectus.
