for anomalous head posture in infantile nystagmus

Background The purpose of this study was to report the effect of combining the Kestenbaum procedure with posterior fixation suture for infantile horizontal nystagmus with anomalous head posture (AHP) in children. Methods Nine consecutive patients who underwent com-bined Kestenbaum procedure plus posterior fixation suture to the recessed muscles at the same time were retrospec-tively studied. All patients were orthotropic before surgery and were followed for at least 6 months. Pre- and postoperative AHP and binocular corrected visual acuity (BCVA), and ocular alignment were assessed. Results Mean age at surgery was 4.8±1.5 years. The average follow-up was 29.7 months. The average head turn preoperatively was 27.4 ° and postoperatively 7.2°. The average net change in AHP was 24.8 ° (P=0.008). Seven of 9 patients (78%) achieved a residual head turn of 10 ° or less. The average Log Mar BCVA was 0.33 preoperatively and 0.31 postoperatively (P=0.68). Only 1 patient needed additional surgery for residual horizontal AHP. No patient developed strabismus. Conclusion Combined Kestenbaum procedure with posterior fixation suture was an effective and stable procedure in reducing AHP of the range of 20 ° to 35 ° in children with infantile nystagmus
