Kestenbaum procedure with posterior fixation suture for anomalous head posture in infantile nystagmus.

摘要

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 combined Kestenbaum procedure plus posterior fixation suture to the recessed muscles at the same time were retrospectively 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 degrees and postoperatively 7.2 degrees . The average net change in AHP was 24.8 degrees (P = 0.008). Seven of 9 patients (78%) achieved a residual head turn of 10 degrees 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 degrees to 35 degrees in children with infantile nystagmus.
