Purpose:
To report clinical findings and surgical management of 4 patients with congenital nystagmus who presented with a new or reversal of their original horizontal compensatory head posture (CHP) after Anderson-Kestenbaum (A-K) surgery.
Method:
Retrospective chart review.
Results:
All 4 patients demonstrated a 40°-45° horizontal face turn at the time of their initial surgery and 3 underwent 20% and one 30% augmented A-K surgery to correct the CHP. The new CHP or reversal of the original CHP was observed at a mean of 4 years (range 1-9 years) after the initial surgery. The reversed CHPs measured 20°, 40°, 20°, and 20°, respectively. These new or residual CHPs were surgically managed in 3 patients and an acceptable head position was achieved in all patients.
Conclusions:
This series of patients points out the occurrence of secondary null points and reversed CHP after surgical correction of initial CHP.
