For many patients with trigeminal neuralgia, oral administration of carbamazepine is highly effective. Micro decompression surgery (Jannetta's operation) is also considered a fundamental treatment. However, there are patients who do not respond to carbamazepine and who hesitate to have surgery. Here, we report 14 cases whose pain was relieved solely by Kampo (7 cases) or by a combination of Kampo and carbamazepine (7 cases). The Kampo formulations used were Goshuyu-to (2 cases), Gorei-san (9 cases), Saiko-keishi-to (1 case), Toki-shigyaku-ka-goshuyu-shokyo-to (1 case) or Mao-bushi-saishin-to (1 case), depending on the “Zheng” of each patient. In trigeminal neuralgia, the nerve root is compressed or adhered to surrounding vessels, such as the superior cerebellar artery. It is highly possible that localized edema at the point of compression is responsible for the pain. The diuretic action of the Kampo may diminish the localized edema around the trigeminal nerve root.

STUDY DESIGN: Retrospective case series. PURPOSE: To clarify the influence of cervical spinal canal stenosis (CSCS) on neurological functional recovery after traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation. OVERVIEW OF LITERATURE: The biomechanical etiology of traumatic CSCI remains under discussion and its relationship with CSCS is one of the most controversial issues in the clinical management of traumatic CSCI. METHODS: To obtain a relatively uniform background, patients non-surgically treated for an acute C3-4 level CSCI without major fracture or dislocation were selected. We analyzed 58 subjects with traumatic CSCI using T2-weighted mid-sagittal magnetic resonance imaging. The sagittal diameter of the cerebrospinal fluid (CSF) column, degree of canal stenosis, and neurologic outcomes in motor function, including improvement rate, were assessed. RESULTS: There were no significant relationships between sagittal diameter of the CSF column at the C3-4 segment and their American Spinal Injury Association motor scores at both admission and discharge. Moreover, no significant relationships were observed between the sagittal diameter of the CSF column at the C3-4 segment and their neurological recovery during the following period. CONCLUSIONS: No relationships between pre-existing CSCS and neurological outcomes were evident after traumatic CSCI. These results suggest that decompression surgery might not be recommended for traumatic CSCI without major fracture or dislocation despite pre-existing CSCS.
