Visual analog scale VAS scores are useful in characterizing the type and intensity of pain and should be completed prior to surgery and at fixed postoperative intervals to monitor effectiveness of therapy. Alleviation of atypical trigeminal pain by stimulation of the Gasserian ganglion via an implanted electrode. As with any other neuromodulation procedure, it goes without saying that permanent implantation should always be preceded by an adequate screening trial to determine effectiveness. The Crucial Context of Acceptance.

Hypothalamic deep brain stimulation for intractable cluster headache: Assuming the trial is successful, the patient is returned to the operating room for internalization of the permanent system and implantation of a pulse generator under general anesthesia. It has been suggested that deafferentation pain may be controlled more effectively by applying stimulation at a level more rostral to the site of deafferentation. A single patient underwent revision due to erosion of the electrode connector.
