Summary
A custom computer-designed surgical guide successfully removed a challenging skull base foreign body. This innovative approach aided precise localization and extraction, leading to a positive patient outcome with minimal complications.
Area of Science:
- Neurosurgery
- Medical Device Design
- Computer-Aided Surgery
Background:
- Foreign bodies at the skull base present significant surgical difficulties.
- Conventional methods may be insufficient for complex skull base foreign body removal.
Purpose of the Study:
- To describe the use of a custom computer-designed surgical guide for foreign body removal.
- To evaluate the efficacy and safety of this novel navigation tool.
Main Methods:
- A patient with a skull base foreign body adjacent to critical neurovascular structures was identified.
- A customized computer-designed surgical guide bar and mounting platform were created within 24 hours.
- The guide was utilized for precise localization and removal of the foreign body.
Main Results:
- Successful foreign body removal was achieved using the custom guide and computer-aided planning.
- The patient experienced no major complications at 10-month follow-up, including no false aneurysm or restricted mouth opening.
- Minor persistent labial numbness was noted, a sequela of the necessary mandibular osteotomy.
Conclusions:
- Custom-designed navigation tools, including computer-aided surgical guides, are effective for skull base foreign body removal.
- This technology offers a viable solution for challenging surgical cases.
- The described method demonstrates successful application in a complex anatomical region.
