Development and treatment of CSF fistula, post-operative headache, cerebellar ptosis in 62 patients who underwent posterior fossa cranioplasty or not following posterior fossa surgery

Objective: The approaches in posterior fossa surgery are used for accessing various tumors and vascular lesions including neuro-glial tumors, vestibular Schwannomas, inclusion tumors, meningiomas. Materials and Methods: A total of 62 patients who underwent operation due to infra-tentorial intra-cranial mass lesion in Neuro-Surgery Clinic between 2014 and 2018 were included in the study. Result: The study was conducted with 62 patients of whom 61.3% (n=38) were males and 38.72% (n=24) were females between 2014 and 2018. While 33.9% (n=21) of the patients underwent cranioplasty, 66.1% (n=41) did not undergo cranioplasty. Conclusion: The preliminary study suggests that cranioplasty is useful for headache and cerebellar ectopy however insufficient for prevention of CNF fistula development.
