Abstract: Objective : To explore the factors associated with visual outcome in patients after microsurgery for tuber-culum sellae meningioma. Methods : The clinical data from 51 patients with tuberculum sellae meningiomawho underwent surgery in our hospital between 1998 and 2007 were retrospectively analyzed. The clinicalrisk factors associated with postoperative visual outcome were evaluated by univariate analysis. Results : Thecomplete resection rate was 80.4%. The vision was improved in 73.2% patients and worsened in 4.9% pa-tients. About 22% patients had no changes in vision. Other postoperative complications included diabetes in-spidus in 8 patients (relieved in 1 week), hypopituitaism in 2 patients, seizures in 2 patients, hypothalamusdysfunction in 1 patient, and intracranial infection in 1patient. The risk factors included age, duration of visualsymptoms, presence of significant peri-tumoural edema, intactness of arachnoid plane and the rate of resec-tion. Conclusion : A standard pterional craniotomy using microsurgical technique provides the necessary expo-sure and enables total removal, with minimum complications. Patient age of more than 60, duration of visualsymptoms longer than 1 year, severe visual symptomatology, presence of significant peritumoural edema, absence of an intact arachnoid plane and total resection were correlated factors for impaired postoperative vision.
