Innervation of Human Cricopharyngeal Muscle By Recurrent Laryngeal and External Branch of Superior Laryngeal Nerve

NCT02761239 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

The investigators hypothesized that, external branch of the superior laryngeal nerve (EBSLN) and/or recurrent laryngeal nerve (RLN) contribute to the motor function of the human cricopharyngeal muscle (CP). The investigators aimed to assess the contribution of the laryngeal nerves (EBSLN and RLN) to the motor activity of the cricopharyngeal muscle, during thyroidectomy with intraoperative neuromonitoring (IONM).

Conditions

  • Larynx

Interventions

DEVICE

The NIM 3.0 Nerve Monitoring System

Electromyography recordings were accomplished with a pair of needle electrodes inserted through the CP muscle, which were plugged into the third and fourth channels of interface-connector box.The recurrent laryngeal nerve(RLN), vagus nerve, external branch of the superior laryngeal nerve(EBSLN) and pharyngeal plexus were stimulated with a current of 1 mA and a frequency of 4 MHz and the event threshold at 100 microV.
