Answer

Answer

In patients undergoing MVD in whom no NVC can be found either by imaging, or at the time of surgery, a nerve disruptive procedure, trigeminal internal neurolysis (TIN) can be performed in which the surgeon thoroughly separates the internal fibers of the nerve as it enters the brainstem. This procedure produces pain relief of equivalent quality and duration to MVD, and in most cases results in nominal facial sensory loss. [21]
