A Retrospective Assessment Cerebrospinal Fluid Leak in Posterior Fossa Surgeries with Different Dural Closure Methods

Description

Abstract (English)

Abstract
Aim: The aim of the present study was to compare the occurrence of Cerebrospinal fluid leak in posterior fossa
surgeries where different dural closure materials are used.
Material & Methods: A retrospective cohort study, conducted in the Department of Neurosurgery, Medical
College Trivandrum Thiruvananthapuram, Kerala, India. All the cases underwent posterior fossa surgeries during
the period of 2 years in the department of Neurosurgery was included in the study. 100 patients were included in
the study. Consent was obtained from all patients and data collected retrospectively from medical records.
Results: There was no significant difference in gender. The total patient population consisted of 35 men (35%)
and 65 women (65%). The etiology of craniotomy had equal distribution as well, with a total of 75 (75%) tumors,
15 (15%) cysts, 6 (6%) chiari malformations, 2 (2%) decompressions, and 2 (2%) inflammations. The incisional
CSF leak within 30 days was noted in 6 patients. Non-incisional CSF leak was noted in 15 patients.
Conclusion: The study concluded that, in cases of posterior fossa surgeries, closure with pericranium has a
significant protection against CSF leak.
