Summary

This study looks at 50 children aged 3-7 with type 1 obstructive sleep apnea who are scheduled for adenotonsillectomy. Researchers want to see if changes in how much children open their mouths during sleep are linked to improvements in their quality of life. Parents will answer questionnaires, and mouth opening will be measured with a special sensor before and after surgery.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will include pediatric patients between the ages of three and seven years old, who consulted with a surgeon at the study center for potential adenotonsillectomy. To be eligible to participate, patients must be beneficiaries of the French single payer national medical insurance system, be able to attend all scheduled visits and comply with trial procedures, and legal guardians must give informed consent. Full inclusion and exclusion criteria are listed in Table 1. The study center is a private French hospital that, due to the single-payer insurance system in France, should include patients from a range of socioeconomic categories and geographical (urban versus rural) locations.
