ABSTRACT

ABSTRACT: Authors evaluated a long-term outcomes of two surgical methods for the treatment of six nerve palsy. Eighty nine patients with paralytic strabismus secondary to sixth nerve palsy undergone surgery in the period from January 1993 to October 2003. Group A included 46 patients, who were treated using a large recession of the medial rectus combined with a supramaximal resection of the lateral rectus. Group B comprised 43 patients in whom were performed the Hummelsheim transposition procedure with or without resection of transposed half-tendon vertical muscles, always combined with recession of medial rectus. The modified split-tendon Hummelsheim procedure involves half-tendon transpositions of the adjacent rectus muscles to the insertion of the paralyzed muscle, coupled with resection of the transposed halves. The mean follow-up was 34.6 months (range, 6 to 114 months). The primary position deviation and the occurence of diplopia after one surgical procedures were compared in the both groups preoperatively and postoperatively. For statistical analysis was used the Student-t test.
