Summary
Navigated lateral skull base surgery requires careful attention to potential errors. Identifying and correcting issues with hardware, software, and patient registration is crucial for successful outcomes.
Area of Science:
- Neurosurgery
- Medical Technology
Background:
- Lateral skull base surgery presents unique challenges for surgical navigation.
- Understanding potential error sources is vital for improving navigated procedures.
Purpose of the Study:
- To identify and analyze disturbing factors in navigated surgical procedures for the lateral skull base.
- To provide guidance for surgeons using navigation systems in this complex anatomical region.
Main Methods:
- Analysis of 85 patient cases undergoing lateral skull base surgery.
- Categorization of errors including hard/software, imaging, patient registration, user, and strategic factors.
Main Results:
- Impairment of camera field affects optical systems similarly to ferromagnetic materials impacting electromagnetic systems.
- Standard patient registration and lack of soft tissue shift compensation can lead to navigation inaccuracies.
Conclusions:
- Surgeons must be vigilant regarding potential malfunctions in navigation devices during lateral skull base surgery.
- Critical attention to detail is necessary for recognizing and interpreting navigation system errors.
