About this study

This prospective study aims to establish and evaluate a predictive model to diagnose OSA with maxillofacial characteristics 3D acquisition.

Read the detailed description

Polysomnography is the gold-standard for obstructive sleep apnea (OSA) diagnosis. However, OSA is still undiagnosed. Maxillofacial profile can influence OSA severity. Morphological characteristics can be identified but are not enough measurable and analysable by physicians. 3D acquisition of maxillofacial characteristics with a user-friendly tool, quick and low-priced could be used to obtain a predictive model as an OSA risk indicator. Thus, the aim of this study is to establish and evaluate a predictive model to diagnose OSA with maxillofacial characteristics 3D acquisition.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 3D acquisition of maxillofacial characteristicsDiagnostic test

    A 3D acquisition of maxillofacial characteristics will be performed for each patient in order to validate a predictive model comparable to data obtained by polysomnography

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Establish and evaluate a predictive model for OSA diagnosis by 3D acquisition of characteristics maxillofacial

    apnea hypopnea index will be measured by polysomnography for each patient and compared to a predictive model establish from body mass index and 3D acquisition (cricomental distance...)

    Measured: 1 measure at inclusion

Secondary outcomes (3)
  1. Sensitivity study from different stages of OSA severity

    OSA severity stages will be apnea hypopnea index <5, <10, <15

    Measured: 1 measure at inclusion

  2. Compare diagnosis performances of predictive model and Berlin or NoSAS questionnaires

    Correlation between the Berlin or NoSAS score and the predictive model results

    Measured: 1 measure at inclusion

  3. Evaluate performances of the combination (Berlin questionnaire + predictive model) to estimate the OSA risk

    Calculate the sensitivity, specificity, predictive positive value and predictive negative value of the combination

    Measured: 1 measure at inclusion

Questions about this trial

What is this clinical trial studying?

A study testing 3D acquisition of maxillofacial characteristics in people with Obstructive Sleep Apnea, run by University Hospital, Grenoble at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Establish and evaluate a predictive model for OSA diagnosis by 3D acquisition of characteristics maxillofacial (time frame: 1 measure at inclusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03632382, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Feb 2021.
