Effect of microsurgicai treatment in tuberculum sellae meningiomas associated with visual impairment (56 cases report)

Abstract

Objective To explore the microsurgical approaches,operative techniques,and clinical results of tuberculum sellae meningiomas associated with visual impairment.Methods An retrospective analysis was made on 56 patients,with tuberculum sellae meningiomas associated with visual impairment,between Jan 2008 and Jan 2012.These patients underwent microsurgery through a variety of surgical approaches,such as the coronal craniotomy unilateral subfrontal approach (22 cases),the frontal-lateral approach (28 cases),and the frontal-temporal approach (6 cases).Results According to the Simpson classification after resection,there were 22 cases of Simpson Ⅰ,28 cases of Ⅱ,and 6 cases of Ⅳ.Visual impairment was improved in 47 cases,unchanged in 7,and worsened in 2.There was no case of death.Conclusions According to the size,location,growth pattern,and adjacent relationship to the important structures of these tumors,suitable surgical approaches should be selected for tuberculum sellae meningiomas before operation.The key point for good results is through the application of the skillful micro-neurosurgical technique.
