ABSTRACT
We describe a new method for radio-frequency mandibular nerve rhizotomy under CT fluoroscopy. A patient with cancer had severe intractable and drug-resistant pain in his left mandibular region. Because he had an anatomic deformity due to cancer invasion and radiation therapy, we planned a mandibular nerve rhizotomy under CT fluoroscopic imaging. The needle was advanced to the mandibular nerve just caudal to the foramen ovale under real-time CT fluoroscopy, avoiding the cancer region. Pain scores of the patient were reduced after the nerve rhizotomy, without any complications.

The surface of a microspherical structure formed in the aqueous suspension of thermal heterocomplex molecules made by heating aspartic acid and proline can adsorb basic amino acids such as histidine, lysine and arginine. It can also adsorb adenine, cytosine, adenosine and cytidine. Electrostatic interactions acting between those monomers to be adsorbed and the absorbing surface are responsible for the adsorption.
