Purpose:
To review the outcome of surgery for strabismus due to ethmoid sinus surgery.
Cases And Methods:
The series comprised 13 cases, 1 of inferior rectus paresis, 1 of superior oblique paresis, 6 of medial rectus paresis, and 5 of medial rectus muscle palsy due to third nerve palsy. In the cases of paresis of the rectus muscle, resection of the rectus muscles was mainly performed. In the cases of palsy of the rectus muscle, transposition of the extraocular muscle with simultaneous recession of the lateral rectus muscle was performed. The major aim of surgery was to bring both eyes into alignment and to eliminate diplopia in the primary position.
Results:
The mean preoperative horizontal deviation of 18.1 degrees of exotropia in the paresis cases was reduced to 1.4 degrees of exotropia after surgery. The mean preoperative vertical deviation of 3.8 degrees of hypertropia was reduced to 1.4 degrees of hypertropia postoperatively. The mean preoperative horizontal deviation of 35.6 degrees of exotropia in the palsy cases was reduced to 9.4 degrees of exotropia after surgery. The mean preoperative vertical deviation of 2.0 degrees of hypertropia was increased to 2.6 degrees of hypertropia postoperatively. Postoperatively, diplopia was absent in 11 cases with a slightly compensatory head posture.
Conclusion:
Surgery for strabismus due to sinus surgery induces improvements in eye position and diplopia.
