Implementing a perioperative protocol for skull base epidermoid cyst (SBEC) surgery reduced cerebrospinal fluid (CSF) diversion needs. This enhanced management also lowered rates of hydrocephalus, CSF leaks, and meningitis post-surgery.

Area of Science:

  • Neurosurgery
  • Cerebrospinal Fluid Dynamics
  • Surgical Outcomes

Background:

  • Skull base epidermoid cyst (SBEC) surgery carries risks like aseptic meningitis and CSF malabsorption.
  • Perioperative management strategies to mitigate these risks require evaluation.

Purpose of the Study:

  • To compare outcomes in SBEC management before and after implementing an institutional perioperative protocol.
  • To assess the impact of the protocol on reducing surgical complications.

Main Methods:

  • A retrospective review of a prospective database of surgically managed SBECs.
  • Comparison of outcomes between patients treated before (2003-2008) and after (2010-2021) protocol implementation.
  • Protocol included intraoperative hyper-irrigation, prolonged postoperative steroids, and aggressive CSF malabsorption management.

Main Results:

  • The post-protocol group (27 patients) showed a significantly lower rate of CSF diversion compared to the pre-protocol group (12 patients).
  • Lower, though not statistically significant, rates of hydrocephalus, CSF leak, bacterial meningitis, and shorter mean length of stay were observed post-protocol.
  • Rates of aseptic meningitis and cranial nerve palsies remained similar between groups.

Conclusions:

  • The implemented perioperative protocol improved CSF dynamics in SBEC surgery.
  • This led to a reduced need for CSF diversion and fewer secondary complications like wound leaks and meningitis.
