Summary
A new CT fluoroscopy technique precisely targeted radio-frequency mandibular nerve rhizotomy for severe, drug-resistant facial pain in a cancer patient. This minimally invasive procedure successfully reduced pain without complications.
Area of Science:
- Interventional Pain Management
- Medical Imaging
- Neurosurgery
Background:
- Severe, intractable pain in the mandibular region poses significant challenges.
- Conventional treatments may be insufficient for cancer-related or post-radiation pain.
- Anatomic deformities can complicate standard interventional pain procedures.
Observation:
- A patient with cancer experienced severe, drug-resistant left mandibular pain.
- Anatomic deformity due to cancer invasion and radiation therapy was present.
- CT fluoroscopy was utilized for precise needle guidance.
Findings:
- Radio-frequency rhizotomy of the mandibular nerve was successfully performed under CT fluoroscopy.
- The needle was accurately advanced to the mandibular nerve, avoiding the tumor site.
- The patient reported reduced pain scores post-procedure.
- No complications were observed.
Implications:
- CT fluoroscopy offers a viable method for precise radio-frequency mandibular nerve rhizotomy.
- This technique can be beneficial for patients with complex anatomy and intractable facial pain.
- It provides a minimally invasive option for managing refractory cancer-related pain.
