摘　　要：目的　寻求测试恒河猴下牙槽神经感觉传导的有效方法。方法　通过对 16只恒河猴 6 8次下牙槽神经感觉传导的测试 ,比较口内进针法及口外进针法 ,找出记录感觉动作电位最稳定的测试方法。结果　其中 3只恒河猴用同心针电极口内进针法记录到的感觉动作电位稳定性和重复性差 ,且操作困难。 16只恒河猴采用口外进针法均可得到清晰、稳定的感觉动作电位。结论　采用同心针电极口外测试猴下牙槽神经感觉传导的方法 ,操作简便 ,重复性好 。Objective To explore a method for making electrophysiologic recording from monkey inferior alveolar nerve (IAN).Methods We investigated INA evoded sensory action potentials of 16 monkeys using two methods of the intraoral electrode insertion and extraoral electrode insertion.Results By means of the intraoral electrode insertion evoked waveforms were unstable in 3 monkey.Evoked waveforms were clear,stable and well repeated in all of 16 monkeys when electrodes were inserted extrorally.Conclusion This study presents a good technique for making electrophysiologic recording from INA of monkeys by using the extraoral electrode insertion.
