The SomnuSeal Oral Mask Is Reasonably Tolerated by Otherwise CPAP Noncompliant Patients with OSA

Abstract EN

Compliance with CPAP is the major limiting factor in treating patients with OSA.

The novel SomnuSeal mask is an oral self-adaptable mask located between the teeth and the lips ensuring that there are no air leaks or skin abrasions.

Fifty patients with AHI>20, who failed previous CPAP trials, were asked to sleep with the mask for one month.

In all patients, the mask was connected to an AutoPAP machine with a heated humidifier.

Efficacy, convenience, and compliance (average usage for 4 or more hours per night) were monitored.

Fifty patients (41 m and 9 f, mean age 57±12 years, BMI 33.6±4.9 kg/m2, and AHI 47±23/h) participated.

Eleven were classified as compliant (average mask usage of 26 nights, 4.7 hours per night), five were only partially compliant (average usage of 13 nights, 2.9 hours per night), and 34 could not comply with it.

In all patients who slept with it, the efficacy (assessed by residual AHI derived from the CPAP device) was good with an AHI of less than 8/hour.

Interestingly, the required optimal pressure decreased from an average of 9.3 cmH2O to 4.6 cmH2O.

The SomnuSeal oral interface is effective and may result in converting noncompliant untreated patients with OSA into well-treated ones.
