Intraoperative Identification and Stimulation of the Glossopharyngeal Nerve
Stopped: No participants have been enrolled to date.
United States0Started 2025-12
Plain-language summary
Published data suggest that the glossopharyngeal nerve innervates pharyngeal musculature important for maintenance of upper airway patency. The investigators propose a study examining the anatomic variation of the glossopharyngeal nerve and the effect of electrical stimulation on muscle recruitment and upper airway patency.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Consenting adults with BMI ≥ 25 and ≤ 40 kg/m2
* Planned resection of parapharyngeal space (PPS) mass without clinical evidence of cranial nerve function deficits based on physical examination
* History of moderate-to-severe Obstructive Sleep Apnea (OSA) as confirmed by previous polysomnogram OR high risk for OSA based on STOP-BANG criteria (STOP-BANG score ≥ 3)
Exclusion Criteria:
* Unable to consent for research due to a pre-existing neurologic condition or language barriers as determined by PI
* History of other primary sleep-related breathing disorder (e.g., central, or complex sleep apnea).
* Previous pharyngeal surgery excluding tonsillectomy (e.g. cleft palate repair, uvulopalatopharyngoplasty)
* Prior history of head and/or neck chemoradiation therapy
* Existing indwelling neurostimulation device (e.g. pacemaker; spinal, vagal, or hypoglossal nerve stimulator)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Change in variation in the conformation of the glossopharyngeal nerve
Timeframe: Collected during a single operative procedure, taking about 15 minutes.
