To establish the surgical results and residual symptoms in 48 cases with unilateral congenital superior oblique muscle palsy that had surgical intervention to the vertical muscles alone.
Myectomy and concomitant disinsertion of the inferior oblique (IO) muscle was performed in 38 cases and myectomy and concomitant IO disinsertion and recession of the superior rectus muscle in the ipsilateral eye was performed in 10 cases. The preoperative and postoperative vertical deviation values and surgical results were compared.
Of the patients who had myectomy and concomitant IO disinsertion, 74% achieved an “excellent” result, 21% a “good” result, and 5% a “poor” result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Of the patients who had myectomy and concomitant inferior oblique disinsertion and ipsilateral superior rectus recession, 50% achieved an “excellent” result, 20% a “good” result, and 30% a “poor” result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001).
Both procedures are effective and successful in patients with superior oblique muscle palsy, but a secondary surgery may be required.
