Could a small wire in the neck replace the CPAP mask?
NCT ID NCT06283030
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early study tested whether a small electrode placed near the tongue nerve could be safely used in people with obstructive sleep apnea. 14 adults who could not use CPAP took part. The goal was simply to see if the nerve could be reached and stimulated, not yet to treat the condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hypoglossal nerve stimulation device
- What this could lead to
- If successful, this could lead to a less invasive implant for treating obstructive sleep apnea without a CPAP mask.
- What could go wrong
- This is a very early proof-of-concept study with only 14 people. It only tests if the nerve can be reached and stimulated safely, not whether it actually treats sleep apnea long-term.
