ABSTRACT
Background: More essential structures are located in the posterior fossa, which is less accessible than any other area of the body. Therefore, posterior fossa surgery necessitates extraordinary caution while touching tissue and special care to make it easier to access the tumor. Patients and Methods: This hospital based case-series study design includes 35 patients, 19 females and 16 males, they were admitted to the Surgical Subspecialties Hospital, during the period between January 2012 and December 2013, for having symptoms and signs of posterior fossa lesions, and were diagnosed as having brain tumors; all of them were older than 16 years. Results: Age group 21-30 years representing 40.0% of the sample 42.8% of them are males. As an immediate post-operative complications, Apnea is found in 2 patients (6.2%), the early post-operative complications include Aspiration pneumonia which found in 4 patients (12.5%), the 7th nerve palsy is reported in 4 patients (12.5%), and Cerebellar dysfunction is found in 2 patients (6.2%), while each of long tract signs, CSF leak, and Tension pneumocephalus are reported in only one patient (3.1%). The late complications and shows that wound infection is found in 3 patients representing (9.3%) and Meningitis is found in only 2 patients constituting (6.2%). Six patients (17.1%) that distributed as 3 (8.5%) patients died due to aspiration pneumonia, 2 (5.7%) patients died due to apnea, and only 1 (2.8%) patient died due to persistent unresponsiveness brain stem edema. Conclusion: Higher mortality was encountered among patients with midline tumors. The main cause of death following posterior fossa surgery was respiratory failure in the postoperative period. It is for this reason that the practicing neurosurgeon, whenever it is feasible and appropriate, may adopt other modalities of treatment, such as stereotactic radio-surgery.
