Summary
Three-dimensional rotational fluoroscopy offers a novel, safe method for cannulating the foramen ovale (FO) during trigeminal neuralgia treatment. This technique enhances visualization, potentially reducing complications associated with standard percutaneous balloon rhizotomy.
Area of Science:
- Neurosurgery
- Medical Imaging
Background:
- Percutaneous balloon rhizotomy is a standard treatment for trigeminal neuralgia.
- Cannulating the foramen ovale (FO) presents known complications.
- A novel technique using 3D rotational fluoroscopy for FO cannulation is presented.
Observation:
- 3D rotational fluoroscopy reconstructs skull base anatomy for optimal FO visualization.
- It allows for needle trajectory assessment, even in challenging anatomies like severe cervical spondylosis.
- Balloon position can be verified in real-time during the procedure.
Findings:
- 3D rotational fluoroscopy enables quick, safe, and straightforward FO cannulation.
- The technique utilizes readily available biplanar fluoroscopy suite equipment.
- This method is expected to reduce complications compared to standard fluoroscopic techniques.
Implications:
- 3D rotational fluoroscopy provides real-time guidance for FO cannulation and balloon placement.
- This technique is a valuable adjunct for percutaneous treatment of trigeminal neuralgia.
- Improved safety and efficacy in neurosurgical interventions.
