Study summary

To learn whether stabilization of the tongue using intraoral suction is tolerable and what effects this approach has on sleep parameters in obstructive sleep apnea.

Read the detailed description

Patients who are newly diagnosed with moderate OSA or diagnosed with OSA in the past 5 years and who are not compliant with continuous positive airway pressure treatment will be identified from the Boston VA Healthcare Sleep Laboratory database and invited to participate in the study. Those patients interested in participating will be consented and then evaluated for adequate nasal patency and oral dentition to assess their eligibility for the study. This is a pilot study primarily assessing tolerability of using intraoral suction to stabilise the tongue at night as well as its effects on sleep parameters. Target enrollment is 40 patients. Those enrolled will have a digital intra-oral scan performed and a custom-fit mouthguard that can transmit low level intermittent suction fabricated. The participant will wear this mouthguard for up to five consecutive nights. They will complete a survey designed to assess tolerability following five nights of wearing the mouthguard. The participant will then have a two night in-hospital polysomnography performed one night with the mouthguard transmitting suction and a second night with no suction. The outcomes will be measured using the tolerability survey scores and the duration and quality of sleep as measured by polysomnography.

Exclusion criteria

Exclusion Criteria:

What researchers measure

Primary outcomes

  1. Number of patients reporting adverse events related to use of intraoral suction to stabilize the tongue as assessed by a survey

    Tolerability and comfort will be assessed by a survey completed by each study subject. Number of patients reporting moderate or more severe pain related to use of intraoral suction to stabilize the tongue as assessed by a self-reported survey using a 5-point pain scale. The survey will be completed by each study subject after having worn the mouthguard for up to 5 consecutive nights in a row. Moderate to severe pain is classified as a score of 3 or higher.after their having worn the mouthguard for up to 5 consecutive nights in a row

    Time frame: Up to 16 weeks

Secondary outcomes

  1. Effect on sleep duration

    Change in sleep duration (minutes) with and without intraoral suction as measured by polysomnography

    Time frame: Up to 16 Weeks

  2. Effect on sleep quality

    Change in percentage time in rapid eye movement (REM) with and without intraoral suction as measured by polysomnography

    Time frame: Up to 16 Weeks
