Study summary

This is a research study of the effect of treating laryngomalacia (floppiness of tissue on top of the voice box that can possibly block breathing) found in association with obstructive sleep apnea (blockage of breathing while sleeping).

The purpose of this study is to determine which is the best treatment for children with obstructive sleep apnea and laryngomalacia: adenotonsillectomy alone or adenotonsillectomy with laser supraglottoplasty (removal of tissue on top of the voice box to open the airway).

Read the detailed description

If you agree to have your child be in the study, you will do the following things:

you are consenting to your child having the adenoid (tissue similar to lymph nodes, found in the back of the throat) and tonsils removed (if not previously performed), direct laryngoscopy (looking in the throat) and bronchoscopy (inspection of the lungs with a long tube-like device down the throat), and randomization (½ will be treated further, ½ will be observed) into treatment and no-treatment arms if your child is diagnosed with laryngomalacia. After starting general anesthesia (putting patient to sleep for procedure), the surgeon will perform direct laryngoscopy (look at the throat and voice box) and bronchoscopy (look at the entrance to the lungs [trachea or windpipe]). If your child is diagnosed with laryngomalacia (flopping of the tissue around the voice box, potentially causing obstruction or blockage), 50% will undergo a further treatment (laser supraglottoplasty, or removal of tissue at the entrance of the voice box) and 50% will be observed. The decision to treat or not treat will be random, as is customary for prospective research trials. All children (both treatment arms will receive a 3 week treatment of a medicine (a proton pump inhibitor) to reduce the level of stomach acid and prevent potential exposure of the larynx (voice-box) to stomach acid. If your child does not have laryngomalacia, no further treatment on the larynx (voice-box) will be performed. Next, adenotonsillectomy will be performed as is common for the Otolaryngologist performing the procedure. Postoperatively, a sleep study will be performed (identical to the preoperative study) ideally 3-6 months after surgery, (but up to one year after) to monitor your child's progress. Additional laboratory tests or drawing of blood is not routine in this procedure, but may be performed as dictated by your child's medical conditions.

Study arms

  • No intervention
    control

    If laryngomalacia is found, then in the control group, no supraglottoplasty will be performed. Only the tonsils and adenoids will be removed.

  • Experimental
    Treatment

    If laryngomalacia is found, then in the Treatment group, a supraglottoplasty with laser will be performed, as well as removal of the tonsils and adenoids. Intervention: supraglottoplasty with laser

    Procedure: supraglottoplasty with laser

Interventions

  • Proceduresupraglottoplasty with laser

    Polysomnogram, fiberoptic flexible laryngoscopy, adenotonsillectomy, direct laryngoscopy, bronchoscopy, laser supraglottoplasty, general anesthesia, a proton-pump inhibitor ibuprofen, acetaminophen with codeine without alcohol, or other narcotic containing medication, antibiotic, possible use of other analgesics per anesthesia None of these procedures are "new" or experimental. Our investigation pertains to a broader use of the laser supraglottoplasty to include children with obstructive sleep apnea and laryngomalacia, as opposed to the more traditional use of laser supraglottoplasty for only severe laryngomalacia in young children

  • Proceduresupraglottoplasty with laser

    laser excision of laryngomalacia (floppy tissue) on one side of the supraglottis

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 25, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
