We assessed the efficacy of modified Kestenbaum procedure for the correction of abnormal head position in 16 patients with the diagnosis of in fantile nystagmus. Instead of Parks 5-6-7-8mm modified Kestenbaum procedure, we performed 6-7-6-7mm modified Kestenbaum on 11 patients with head turn of 20-30, 20% augmented procedure(7.2-8.4-7.2-8.4mm) on 4 patients with head turn of 30 or more, and-1mm procedure(5-6-5-6mm) on 1 patent with head turn of less than 20. In the average follow-up of 7 months, 10 patients(62.5%) showed head turn of less than 5, in which 14 of 16 patients had less than10 .87.5% of the patients showed satisfactory correction of abnormal head position., 12 prism diopter of exotropia was noted postoperatively in 1 case but the duction was not limited in any case. From the above results, we conclude that 6-7-6-7mm modified Kestenbaum nystagmus.
