Intraoperative Ansa Cervicalis Nerve (ACN) Stimulation

Completed · Not applicable

Conditions studied: Head and Neck Cancer, Obstructive Sleep Apnea

In brief

Recently published data suggest that stimulation of the infrahyoid strap muscles increases pharyngeal patency in patients with obstructive sleep apnea, but the innervation of these muscles by the ansa cervicalis is variable. The investigators propose a study examining the anatomic variation of the ansa cervicalis and the effect of neurostimulation on muscle recruitment.
