16.1 Neuroanatomy neurophysiology neuropathology 2006406 The value of trigemino-cervical reflex in the diagnosis of Arnold-Chiari malformation. ZHENG Ju-yang, et al. Dept Neurol, The 3rd Hosp Peking Univ, Beijing 100083. Chin J Neurol 2006;39(4):236-237. Objective:To study the value of trigemino-cervical reflex (TCR) in the diagnosis of Arnold-Chiari malformation (ACM) and the post-operative evaluation. Methods:Thirty patients from the department of neurology and neurosurgery, the Third Hospital, Peking University, who were diagnosed as ACM by head-MRI, underwent neuroelectrophysiological examination for TCR before and after operation. The parameters observed were latency P19, N31 and Value A (the square root of the amplitude), and wave form was also observed. Results:Preoperatively, 27 patients (90%) showed abnormal TCR with lengthened latencies of P19, N31, the difference of value A between two sides increased and some waves disappeared. After operation, TCR in 24 patients (80%) showed improved:the latency- became normal, and the wave appeared. All patients showed improved head MRI.
