Summary
Navigational guidance improves success rates for percutaneous balloon compression (PBC) in trigeminal neuralgia patients experiencing technical difficulties. This technique enhances foramen ovale cannulation, leading to successful pain relief and improved safety.
Area of Science:
- Neurosurgery
- Medical Imaging
Background:
- Percutaneous balloon compression (PBC) is a standard treatment for medically refractory trigeminal neuralgia (TN).
- Technical failure to cannulate the foramen ovale (FO) under fluoroscopy presents a significant challenge in some PBC procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of intraoperative navigation for PBC in patients with prior technical failure to cannulate the FO.
- To assess the role of neuronavigation in improving FO cannulation success rates.
Main Methods:
- Retrospective analysis of 174 patients undergoing PBC for TN.
- Detailed description of the neuronavigation technique: pre-operative CT scan, image registration, and intraoperative guidance for FO cannulation.
- Focus on 5 reoperated patients who experienced prior FO cannulation failure.
Main Results:
- Neuronavigation-assisted PBC was successfully completed in all reoperated patients.
- Complete immediate postoperative pain relief was reported by all patients.
- No intraoperative or postoperative complications were recorded in the neuronavigation group.
Conclusions:
- Intraoperative navigation is a valuable tool for overcoming technical challenges in PBC, particularly for foramen ovale cannulation.
- Neuronavigation offers significant advantages, enhancing procedural success, efficiency, and safety in trigeminal neuralgia treatment.
