Freezing the tongue and palate: a new approach to treat sleep apnea
NCT ID NCT07021833
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study tests a device that uses freezing (cryoablation) on the tongue and soft palate to treat moderate to severe obstructive sleep apnea. It is for adults aged 22 to 70 who cannot or will not use standard treatments like CPAP or mouthguards. The goal is to see if the procedure is safe and can reduce sleep apnea events.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Cryosa System (cryoablation device)
- What this could lead to
- If successful, this could offer a one-time procedure to reduce sleep apnea severity for people who cannot tolerate standard treatments like CPAP.
- What could go wrong
- This is a small, early pilot study with no control group. The procedure involves freezing tissue, which carries risks like swelling, pain, or temporary swallowing problems. Long-term effectiveness is unknown.
