| Popis: | Objectives/Hypothesis: We report a new surface technique for studying sensory conduction in the superior laryngeal nerve (SLN). Study Design: Prospective controlled cohort study at an academic tertiary care hospital. Methods: Surface stimulation of the vagus nerve 7–10 cm proximal to a surface electrode placed over the cricothyroid muscle was performed in controls and in subjects with needle electromyographic-confirmed laryngeal neuropathy. Cathodal stimulation was applied below the mastoid process behind the sternocleidomastoid muscle. Nerve conduction parameters were determined. Results: Noninvasive SLN evoked potential studies were performed on healthy volunteers (n = 28) as well as neuropathic subjects (n = 27). Compared to controls, the neuropathic subjects had statistically significant differences in baseline-to-peak amplitude, conduction velocity, and intrasubject side-to-side amplitude ratio (P |
