Long-term Evaluation of Nasopharyngeal Airway in Hypotonia

"The ssNPA device is a flexible, medical-grade silicone, nasal tube that is self-inserted into the airway through one nostril and worn during the night. It can also be used during the day. The device works by supporting collapsed airway muscles and keeping the airway open.~In addition to wearing the device, study team members will call monthly and collect certain data, and medical information and participants will be asked to have a sleep study at the 12-month visit."
