Posterior fossa surgeries are generally complicated by difficulties in creating a watertight dural closure, which often requires the use of dural substitutes. In particular, surgical procedures at this location are associated with an increased rate of fluid leakage (cerebrospinal fluid (CSF)) or inflow (blood, air, etc.) creating hydrodynamic complications. Effective sealing of the dura is required to prevent such complications and infections by minimizing the introduction of irritating blood products into the CSF. Since true hermetic dural seals are often impossible to achieve, dural sealants have been developed that can be applied to the sutured dural perimeter to help prevent complications related to CSF. Adjuvant use of such sealants may be prudent, particularly in posterior fossa surgeries, as the incidence of CSF leakage has been reported to be as high as approximately 15-28% with such surgeries, with an increased risk of leakage. 5.84 times greater than supratentorial procedures.
