Understand neurectomy. Neurectomy involves removing a part of the trigeminal nerve. This invasive,ablative procedure is reserved for patients who are refractory to other treatments or who cannot undergo the alternative surgical procedures. 
- Neurectomies are often performed when a blood vessel is not found pressing on the nerve during an MVD.
- During the procedure, different portions of the trigeminal nerve’s branches are removed to grant pain relief.
