• Electromyography of the intrinsic laryngeal muscles has not been widely used, partly because of the difficulty of accurate insertion and stabilization of existing electrodes. The sampling portion of our original electrode has been redesigned. Two needle electrodes, 4 mm in length, protrude from a truncated coneshaped, nonconducting body that has been fashioned to sit in the laryngeal ventricle. The depth of insertion is controlled, and the device resists accidental extrusion.
