Background:
Bilateral sixth nerve paralysis is a rare motility disturbance. The functional and cosmetic problems, operative management and postoperative outcome in three patients are presented.
Material And Methods:
We report on the pre- and postoperative findings of three patients who in one operative session received bilateral transposition surgery in modification of the Hummelsheim procedure.
Results:
All three patients postoperatively showed good cosmetic results with no significant head posture for far and near fixation. The abduction deficiency was reduced. In one case a field of binocular single vision at far fixation was established. This field was positioned centrally and measured 15 degrees in diameter. No intraoperative or postoperative complications occurred.
Conclusion:
Simultaneous bilateral transposition surgery as a modified Hummelsheim procedure can reduce head turn in patients with severe bilateral abduction deficiencies and may reestablish limited binocular single vision. In regard to their psycho-social interactions, the patients benefit from the diminished angle of squint.
