Nineteen months following implantation of bilateral electrodes in the STN for Parkinson's disease, the patient underwent maxillary tooth extraction followed by radiofrequency diathermy, in which the induction coil was placed on alternate cheeks to induce heating of the tissue to hasten recovery. By the end of the one-hour procedure, the patient could not be aroused and was insensitive to pain. MRI revealed bilateral lesions in the immediate vicinity of the electrodes. The patient was ultimately discharged to a skilled nursing facility with little recovery of motor function or consciousness. The authors state, "Our case illustrates that exposure of the [implantable pulse generator], leads or electrodes to high-energy electric or magnetic fields poses a danger for tissue damage in the region of the electrodes...It is important for the physicians to be aware of this adverse event and to educate their patients to avoid exposure to RF diathermy in the vicinity of the IPGs, leads and electrodes."
