Outcomes for schwannomas (100%, 1 year survival rate) and meningiomas
(100%, 1 year survival rate), in which total excision was done, were excellent with a score in excess of 90 (Table-2).
In patients aged above 40 years, Astrocytomas accounted for 12 cases, Meningiomas
for 11 cases, Pituitary macroadenomas accounted for 2 cases, Central neurocytoma and secondaries accounted for 1 case each.

(WHO grade I-II) constituted the predominant tumors among the total cases (60 and 59, respectively) [Table 3].
Most of those epidermoids cases were below 40 years and those of acoustic neuroma and meningioma
were above 40 years.
There were 42 cases of meningiomas
, 25 craniopharyngiomas, and 12 pituitary adenomas [Figure 2],[Figure 3],[Figure 4].
