Intraoperative Ansa Cervicalis Nerve (ACN) Stimulation
Intraoperative Identification and Stimulation of the Ansa Cervicalis Nerve Plexus
Source: ClinicalTrials.gov · Last updated 6 Aug 2026
Brief summary (registry, in English)
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.
