Pak J Neuro Surg Jan ;22(1):7-16.

Objective: This is a prospective study. Posterior fossa tumors are a common entity presented in our tertiary care neurosurgical setup. Although the treatment of posterior fossa tumor has underwent a lot of changes over the period of last two decades but unfortunately in the developing countries the Neurosurgical facilities are still not up to the mark.Materials and Methods: We analyzed the posterior fossa surgery done for the last six months (Feb. 2017 – Aug. 2017) in Neurosurgery Unit I of Punjab Institute of Neurosciences.Results: A total of 15 cases were operated from Feb 2017 to Aug 2017. Immediate outcome was seen at the time of discharge. Nine out of 15 patients were female (60.00%), 6 patients were male (40%). Maximum 6 cases (40.00%) were seen in 3rd decade of life. Main presenting complain was headache 3 cases (20.00%) followed by vomiting 7 cases (46.66%), vertigo in 5 cases (33.33%), hearing and visual loss in 4 cases (26.66%) and balance disturbance was observed in 3 cases (20.00%). Regarding location 6 cases (40.00%) were tumor midline posterior fossa SOL, 5 cases (33.3%) were CP angle lesions, 3 cases (20.00%) were in cerebellar hemisphere and 1 case (06.60%) was noted in the 4th ventricle. Nine of procedure (60.00%) remained continued for 4 – 8 hours and remaining 6 took up to 4 hours (40.00%). Gross total excision was achieved in 5 cases (33.33%), Maximum debulking (more than 80 percent tumour removal) was achieved in 10 cases (66.66%). Associated procedure V-P Shunt was done in 8 cases (53.33%) and EVD in 4 cases (26.6%).Complications: CSF leakage and re-exploration for dural repair was needed in 1 case (06.60%).Outcome: Ten patients were discharged on different status (66.66%) while mortality was noted in 5 cases (33.33%).
