Abstract
Background: Meningiomas are the most common primary intracranial tumors. Visual deterioration is the first symptom for most patients with anterior and middle fossa meningiomas. The main aim of surgery is the total removal of the tumor, resulting in improvement or preservation of preoperative visual status.
Objective: To assess a 30-day visual outcome after surgical treatment of anterior and middle skull base Meningiomas.
Methods: Institution-based prospective cross-sectional study was conducted among hospitalized and operated patients from September 1, 2020, to August 31, 2020. Early postoperative visual outcome and associated factors affecting visual outcome were determined using the WHO visual criteria. Bivariate and multivariate correlation analysis was performed to identify associated variables. The p-value of <0.05 was considered significant.
Results: Among the 43 patients enrolled, the majority 40(93%) were females and 27(62.8%) of the patients were under the age of 45. The commonest presenting symptoms were headache and visual impairment in 41(95.3%) and 33(78.7%) of patients respectively. Postoperative visual improvement was found in 21(48.8%) of patients whereas 18(41.9%) of patients had a similar course and 4(9%) of the patients deteriorated. Age, duration of visual deterioration, peri-operative visual status, tumor size, optic canal extension, and Simpson grading of resection were found to have a significant association with visual outcome.
Conclusion: Postoperative visual improvement was found in 21(48.8%) of patients, which is comparable with most studies. The postoperative visual outcome is favorably affected by a shorter duration of visual deterioration before surgery, better preoperative visual status, and tumor size less than 4cm.
