Ansa cervicalis plexus branches were documented during surgical dissection. In a subset of participants, an electrode was placed on branches of the common sternothyroid trunk innervating the sternothyroid and sternohyoid muscles. Hyolaryngeal excursion with neurostimulation was recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Measurements were collected from 39 of 50 participants. Reasons for intraoperative exclusion included significant radiation fibrosis (n\u2009=\u20094), nodal disease burden (n\u2009=\u20093), and surgeon preference (n\u2009=\u20094). The mean lengths of the common sternothyroid trunk and sternothyroid branch were 37.6\u2009\u00b1\u200915.0\u2009mm and 20.4\u2009\u00b1\u20098.1\u2009mm, respectively. Their respective mean diameters were 2.1\u2009\u00b1\u20090.7\u2009mm and 1.5\u2009\u00b1\u20090.5\u2009mm. The distance from sternothyroid branch muscle insertion to the sternum varied substantially (12.8\u2009\u00b1\u200914.8\u2009mm). Nine patients underwent neurostimulation of the common sternothyroid trunk. The amplitude of first observed muscle contraction was 0.35\u2009\u00b1\u20090.18\u2009mA and maximal was 0.57\u2009\u00b1\u20090.40\u2009mA, during which the hyolaryngeal complex descended by 13.6\u2009\u00b1\u20094.6\u2009mm. In patients with anatomy amenable to neurostimulation of other nerve branches, stimulation of the common sternothyroid trunk produced the greatest hyolaryngeal descent (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The minor variability observed in ansa cervicalis nerve diameter across patients and branches supports the feasibility of a standardized electrode design for an implantable neurostimulation device.
