Area of Science:

  • Neurosurgery
  • Otolaryngology
  • Oncology

Background:

  • Bifrontal craniotomy with skull base osteotomies can lead to infections due to sinus and nasal structure involvement.
  • Identifying infection rates and prevention strategies is crucial for patient outcomes.

Purpose of the Study:

  • To examine the infection rate in patients undergoing bifrontal craniotomy with skull base osteotomies.
  • To evaluate the potential of the bifrontal osteoplastic flap in infection prevention.

Main Methods:

  • Retrospective single-center study of a patient database.
  • Analysis of 20 patients who underwent bifrontal craniotomy with skull base osteotomies.

Main Results:

  • Six patients (30%) developed infections, with all cases involving nasal pathology and intracranial extension.
  • Infected patients often required craniectomy and long-term intravenous antibiotics.
  • The bifrontal osteoplastic flap is proposed as an adjunct for infection prevention.

Conclusions:

  • Infection is a common complication following bifrontal craniotomy with skull base osteotomies.
  • The bifrontal osteoplastic flap may reduce infection risk in high-risk procedures like esthesioneuroblastoma surgery.
