Background & Aims
This study aims to showcase our institution’s experience with cone-beam computed tomography (CBCT) guided percutaneous trigeminal rhizotomy, a prevalent method for treating trigeminal neuralgia.
Methods
A retrospective review was conducted on cases of trigeminal rhizotomy performed for craniofacial pain at our institution. Key parameters such as procedure duration, radiation exposure, and patient outcomes were meticulously documented.
Results
Between 2022 and 2023, a total of 25 trigeminal rhizotomy procedures were executed. Of these, six were conducted using a laser-guided percutaneous approach, while the remainder employed the traditional CBCT-guided technique. All patients reported significant pain relief at the 3-month post-procedure mark. The average duration of the procedures was approximately 0.62 hours.
Conclusions
The implementation of CBCT-guided, with or without the adjunct of laser guidance, for trigeminal rhizotomy has proven to be a viable and efficacious option for the management of craniofacial pain.
