Improving surgical outcomes for children with obstructive sleep apnea using advanced imaging techniques

Official title: Improving Outcomes in Pediatric Obstructive Sleep Apnea With Computational Fluid Dynamics

Run by Children's Hospital Medical Center, Cincinnati · NCT04991389 · Data updated 2026-11-12

This study is testing a new tool that uses advanced imaging to help doctors predict how well surgery will work for children with sleep apnea who haven't improved with other treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged 3 to 18 with persistent moderate or severe OSA after adenotonsillectomy who have failed CPAP treatment.

Probably not a fit

Patients who are adequately treated with CPAP or have contraindications to sedatives will not benefit from this study.

What this trial studies

This project aims to develop a validated computational tool that predicts surgical outcomes for pediatric patients suffering from obstructive sleep apnea (OSA). The study focuses on children aged 3 to 18 who have persistent moderate or severe OSA after adenotonsillectomy and have either failed CPAP treatment or are opting for surgery. By utilizing computational fluid dynamics (CFD) simulations alongside real-time magnetic resonance imaging (MRI), the research seeks to compare various surgical options virtually, enhancing the decision-making process for individualized treatment. The goal is to improve the efficacy of surgical interventions aimed at alleviating airway obstruction in these patients.

Why it matters

Potential benefit: If successful, this tool could significantly improve surgical outcomes for children with obstructive sleep apnea by providing tailored treatment options.

How similar studies have gone: While CFD simulations have been used in other contexts, this specific application for predicting surgical outcomes in pediatric OSA is novel and has not been extensively tested.

Inclusion Criteria:

* Male or Female
* Subjects between the ages of 5 to 18 only for Aim 1 and xenon use
* Subjects 3-18 years of age for Aims 2 and 3
* Subjects with persistent moderate or severe OSA after adenotonsillectomy. - -- Persistent moderate or severe OSA will be defined as an oAHI \> 5 per hour of sleep.
* Clinical indication or suspicion of upper-airway obstruction. Examples include but not limited to hypertrophy of the lingual tonsils, disproportionately large tongue, or micrognathia.
* Subjects who have failed a trial of CPAP.
* Subjects whose parents elect to pursue surgery without a trial of CPAP.
* Subjects who require a surgical procedure for OSA based on the clinical assessment of the surgeon (otolaryngologist or plastic surgeon).

Exclusion Criteria:

* Children adequately treated with CPAP.
* Children with braces/metal rods.
* Children who have a contraindication to sedative.
* Standard MRI exclusion criteria as set forth by the CCHMC Department of Radiology.
