A Case of Muscle Transplantation in the Lateral Rectus Muscle Paralysis

ABSTRACT

Muscle transplanation surgery is presently widely accepted as a good precedure not only for cosmetic, but also for functional results, a concept to which Marina's observations on the absence of fixed and predetermined functions in the nuclei and associated tracts of the oculomotor system give great support; however, not everyone is in agreement with this concept. This paper report one case in which the total transplantation of the vertical rectus muscles midway between their insertions and the insertion of the lateral rectus muscle were carried out, in addition recession of the medial rectus muscle and resection of the paralyzed lateral rectus muscle. Our case have been followed up during 8 months to rule out late complications, aspecially ocular movement and diplopia. No late complications, however, have been found up to remaining underaction of the right superior and inferior oblique muscles and also medial rectus muscle. The eyes were straight with abduction of the right eye up to 40 prism diopters. Binocular vision was present and there was no diplopia. The cosmetic result was excellent.
