• Study Type: interventional
• Target: 58
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to assess the site, pattern and degree of upper airway collapse before and during hypoglossal nerve stimulation (HNS) treatment using clinical standard drug-induced sleep endoscopy (DISE) and using a novel, non-invasive method predicting site of collapse from raw polysomnography (PSG) data. Furthermore, outcomes will be compared between responders and non-responders.

Conditions

Obstructive Sleep Apnea

Keywords

Hypoglossal nerve stimulation; Drug-induced sleep endoscopy

Outcome Measures

Primary Outcomes (1)

• Δ%area-of-collapse at the level of the lateral walls

  The percentage of the area of collapse at the level of the lateral walls - measured using DISE - will be calculated using ImageJ software. The percentage difference of collapse between baseline and one-year follow-up will be calculated.

  Between baseline and one year follow-up

Secondary Outcomes (4)

• Δ%area-of-collapse at the level of the palate, tongue base and epiglottis

  Between baseline and one year follow-up

• Δ%area-of-collapse at each possible site of upper airway collapse (palate, lateral walls, tongue base, epiglottis) in responders and non-responders

  Between baseline and one year follow-up

• DISE-score during baseline DISE and during one-year follow-up DISE.

  At baseline and at one-year follow-up

• Non-invasive site and pattern of collapse

  At baseline and at one-year follow-up

Study Arms (1)

Receiving hypoglossal nerve stimulation (HNS)

OTHER

All included patients will be part of this arm. Patients who are eligible for HNS-therapy for obstructive sleep apnea (OSA) will be invited to participate in the study. Data from the baseline PSG and baseline DISE as part of the standard pathway for HNS-eligibility will be accessed and collected. All patients will undergo HNS-implantation and receive HNS-therapy as part of the standard pathway. After one year of treatment, information from the one-year follow-up PSG as part of the standard pathway will be collected. Furthermore, patients will undergo an additional one-year follow-up DISE.

Device: Hypoglossal nerve stimulation implant; Diagnostic Test: Polysomnography; Procedure: Drug-induced sleep endoscopy (DISE)

Interventions

Polysomnography DIAGNOSTIC_TEST

A PSG at one-year follow-up is part of the standard follow-up pathway in patients receiving HNS therapy. In this study, PSG data will be collected from both baseline and one-year follow-up PSGs to assess treatment effect. Additionally, PSG data will be used for non-invasive prediction of the site and pattern of collapse using a novel, validated tool developed at our research group.

Receiving hypoglossal nerve stimulation (HNS)

Drug-induced sleep endoscopy (DISE) PROCEDURE

Drug-induced sleep endoscopy (DISE) is the clinical standard diagnostic test to assess site, pattern and degree of upper-airway collapse in OSA. Baseline DISE is part of the standard clinical pathway for HNS eligibility. In this study, DISE data will be collected from routine baseline DISE without any additional procedures for the patient. They will undergo an additional DISE at one-year follow-up to assess the effect of HNS-therapy on site, pattern and degree of collapse. Both DISEs will be performed according to routine clinical practice in the operating theatre. Sleep will be induced using 1.5 mg bolus injection midazolam and target-controlled propofol infusion (2.0 - 3.0 μg). A flexible fiberoptic nasopharyngoscope will be transnasally inserted. Site, pattern and degree of collapse will be assessed using a standardized scoring system. Other maneuvers, including chin-lift, the use of a simulation bite or lateral position of the head will be performed according to clinical practice.

Receiving hypoglossal nerve stimulation (HNS)

Hypoglossal nerve stimulation implant DEVICE

The hypoglossal nerve stimulation (HNS) implantation and therapy will be performed according to the standard clinical practice without additional procedures. Information about the surgical procedure will be collected. HNS implant information and settings will be collected throughout the study until the last study measurement (one year follow-up PSG and DISE) for that patient. No additional measures or interventions as part of the research project will be performed during implantation or treatment with HNS.
