Study Will Test the Theory That Training With the Facial-Flex Exercise Device Will Improve Snoring in Patients

Subjects will be studied before and after 6 weeks of Facial-Flex training using portable
monitoring. There will be 8 patient visits and 2 additional trips to the sleep center to
return the portable sleep monitor.

Inclusion Criteria:

- Patients with a history of loud snoring but no observed breathing pauses by
bedpartner (or only very mild obstructive sleep apnea on a previous sleep study
within the prior year) will be enrolled.

- Very mild sleep apnea is defined here as an apnea-hypopnea index (AHI) < 10/hour).

- This assumes that the AHI is computed using hypopnea defined as a 30% drop in the
flow signal associated with a 4% or greater arterial oxygen desaturation.

Exclusion Criteria:

- Prior upper airway surgery

- Daytime sleepiness (Epworth sleepiness scale >12/24), (obesity BMI > 35 kg/M2)

- Significant arterial oxygen desaturation defined as 5 minutes or more with an
arterial oxygen desaturation less than 88%

- Severe insomnia with less than 4 hours of sleep per night

- Uncontrolled psychiatric disorder

- Any disorder causing facial weakness

- Pregnancy

- TMJ problems.
