Area of Science:

  • Neurosurgery
  • Neurological Surgery
  • Medical Device Technology

Background:

  • Frame-based stereotactic surgery has been a cornerstone for precise brain interventions.
  • The migration towards frameless and pinless neuronavigation systems necessitates a clear understanding of frame-based system safety.
  • Establishing a benchmark for complications is vital for comparing evolving surgical navigation techniques.

Purpose of the Study:

  • To establish a benchmark for complications associated with frame-based stereotactic surgery.
  • To assess the safety profile of frame-based stereotactic surgery over an extended period.
  • To provide data for comparing frame-based systems with newer neuronavigation approaches.

Main Methods:

  • Retrospective analysis of a database of 2,651 patients undergoing frame-based stereotactic surgery over 28 years.
  • Assessment of complication rates, including intraoperative bleeding, seizures, infections, and mortality.
  • Utilizing routine intraoperative imaging to detect immediate complications.

Main Results:

  • A low rate of new blood products (2.6%) was detected post-biopsy, with only 0.36% requiring craniotomy.
  • Perioperative seizures occurred in 0.36% of patients; burr hole infections in 2 patients.
  • Mortality directly related to surgery was 0.08% (2 deaths).

Conclusions:

  • Frame-based stereotactic surgery exhibits a well-defined and favorable safety profile.
  • The established complication rates serve as a benchmark for evaluating newer neuronavigation techniques.
  • This study validates the long-term safety and efficacy of frame-based stereotactic surgery.
