Objective To explore the microsurgical technique to treat the tuberculum sellae meningiomas(TSM) and the curativeeffect of microsurgery on them.MethodsThe clinical data of 45 patients with TSM, of whom, 22 underwent microsurgery via theunilateral subfrontal approach, 5 via the cerebral longitudinal fissure approach, 15 via pterional or extended pterional approach and 3 viathe combined pterional and subfrontal approach from January, 2007 to July, 2013, were analyzed retrospectively.ResultsSimpson gradeⅠ resection of the tumors was achieved in 23 patients, grade Ⅱ in 14, grade Ⅲ in 5 and grade Ⅳ in 3. The rate of gross total resectionwas 82.3%(37/45). Of 37 patients with disturbances of visual acuity and/or visual field before the operation, 27(73.0%) were improved,5 unchanged and 4 worsened. No patients died after the operation.ConclusionsThe main method to treat TSM is microsurgery. Thechoice of surgical approach should be based on the tumor size, growth pattern of tumor, degree of visual disturbance and experience ofsurgeon in the patients with TSM. Understanding the microanatomy related to the saddle area and skillful microsurgical techniques arekey to the good curative effect of microsurgery on TSM.
