- Potentiality of Clinical Application of Laryngeal Sensory Evoked Potentials
説明
A number of clinical techniques have been used to evaluate the motor system for deglutition. However, any effective clinical evaluation procedure for the function of the laryngeal sensory system has not been established. We previously reported on evoked potentials on the dural surface elicited by electrical stimulation of the superior laryngeal nerve (SLN) as a reflection of activities in the brain stem and cortex in anesthetized cats. This evoked potential was named LSEP (Laryngeal Sensory Evoked Potential). In this study, we have attempted to establish a less invasive procedure for measuring LSEP. The procedures adopted were, 1) recording from the surface of the scalp using chlorided silver disc electrodes and 2) stimulation by inserting a bipolar platinum hooked wire electrode into the laryngeal mucosa. Evoked potentials were detected using these less invasive procedures, and the response morphologies and relative timing of LSEP components were quite similar to those obtained with the previous technique in a given cat. The amplitude of potentials were slightly lower, and the latencies were slightly longer in the less invasive techniques than in the previous method. These results suggest that this LSEP method might be applicable to humans as a non-invasive method for evaluating the function of the laryngeal sensory pathway.
