A modified Fox pentagon technique performed using a polytetrafluoroethylene sling in frontalis suspension to treat blepharophimosis syndrome

Abstract

The purpose of this study was to evaluate the functional and cosmetic outcomes of a new modified Fox pentagon technique performed using polytetrafluoroethylene in frontalis suspension surgery for blepharophimosis syndrome. This retrospective study enrolled 40 patients diagnosed with blepharophimosis syndrome from March 2016 to October 2018. All patients underwent frontalis suspension using a new modified Fox pentagon technique. The functional and cosmetic outcomes were evaluated. After the operation, the mean palpebral fissure height increased from 2.68 to 6.93 in right eyes and from 2.73 to 6.98 in left eyes. The mean MRD1 increased from 0.53 to 3.76 in right eyes and from 0.50 to 3.78 in left eyes. While preoperative to postoperative differences were statistically significant ( p < 0.01), there were no significant differences between right and left eyes either before or after the surgery ( p > 0.01). All patients achieved good cosmetic results with an average score of 0.6. We have experimentally created a modified Fox pentagon technique performed using a polytetrafluoroethylene sling in a frontalis suspension to treat BPES; this approach yielded favorable cosmetic and functional outcomes.
