PURPOSE: To report the effectiveness of large-segment superior oblique tendon expanders for severe @entity3312 . METHODS: Medical records of 12 consecutive @entity1 with severe @entity3312 were evaluated retrospectively. All @entity1 had a hypotropia > 20 prism diopters in primary position. A superior oblique tendon lengthening procedure, using a 10- to 12-mm-long silicone band, was performed on each @entity1 . Preoperative and @entity86 patterns were analyzed, and the final results were graded as "excellent," "good," "fair," "poor, undercorrected" and "poor, overcorrected." RESULTS: As of the last recorded follow-up examination (mean, 32 months), three @entity1 had an excellent result, six had a good result, three had a fair result, and none had a poor result. All @entity1 experienced an improvement in their severe @entity3312 , with 100% showing a postoperative primary-position hypotropia < 8 prism diopters. Postoperative limitation of elevation in adduction was either -1 or -2 for all @entity1 . No @entity1 required further surgery, and no extrusions of the implants were noted. CONCLUSION: The superior oblique tendon expander procedure appears to be an effective tool in the surgical treatment of severe @entity3312 . The use of a large-segment (10- to 12-mm) band seems to be an appropriate choice when dealing with @entity1 having primary-position hypotropia > 20 prism diopters.
