What this trial studies

This study investigates the anatomical variation of the ansa cervicalis nerve and its role in stimulating the infrahyoid strap muscles during neck dissection for head and neck cancer. Patients undergoing this procedure will have their ansa cervicalis nerves dissected, and measurements will be taken to assess the nerve's anatomy. An electrode will be applied to stimulate the muscles, with the aim of improving pharyngeal patency in patients with obstructive sleep apnea. The study is designed as a single-arm physiology assessment without a control group.

Who should consider this trial

Good fit: Ideal candidates are adults scheduled for neck dissection for cervical lymphadenectomy due to head and neck cancer.

Not a fit: Patients with prior neck surgery affecting the infrahyoid strap muscles or those unable to consent due to neurological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance treatment options for patients with obstructive sleep apnea by improving muscle function and airway patency.

How similar studies have performed: While there is emerging data on muscle stimulation for obstructive sleep apnea, this specific approach involving the ansa cervicalis nerve is novel and has not been extensively tested.
