Medial XXXX : clinical outcome and recurrence rate.

@entity5 @entity1 @entity1653
OBJECTIVE: To provide clinical data concerning the visual outcome and recurrence rate of medial @entity1653 in consideration of two different subgroups of this @entity5 entity. METHODS: Among 256 @entity1653 , there were 108 medial @entity1653 of globoid shape. They were classified into Group 1 (without cavernous sinus involvement) and Group 2 (with cavernous sinus involvement). En @entity1653 were excluded from the analysis. The charts of the @entity1 including surgical records, discharge letters, follow-up records, and imaging studies were analyzed retrospectively. RESULTS: There were 39 Group 1 @entity5 and 69 Group 2 @entity5 . For microsurgical @entity5 removal, the frontolateral (15.7%) or the pterional approach (84.3%) was performed. Total resection was achieved in 92.3% of @entity1 with Group 1 @entity5 and 14.5% of those with Group 2 @entity5 . Radiological recurrence was observed in 7.7% (Group 1 @entity5 ) and 27.5% (Group 2 @entity5 ). The mean follow-up time was 79.04 months (6.59 yr). Improvement of visual function (or stable visual function) was observed in 56% (44%) of @entity1 with Group 1 @entity5 , in 30% (60%) with newly diagnosed Group 2 @entity5 , and 10% (70%) undergoing recurrent surgery for Group 2 @entity5 . CONCLUSION: Group 1 @entity1653 present a more favorable subgroup with fortunate visual outcome. In Group 2 @entity5 , visual improvement was less favorable and radical removal is limited because of cavernous sinus infiltration, with consequential higher recurrence rates. @entity1 harboring recurrent Group 2 @entity5 with deteriorating visual function profit from microsurgery because vision can be preserved on the same preoperative level in the majority.
