Self-Supporting Nasopharyngeal Airway (ssNPA) Treating Upper Airway Obstruction in Hypotonia
The researchers are investigating if the Self-Supporting Nasopharyngeal Airway (ssNPA) device can be used in the treatment of obstructive sleep apnea in children with Hypotonic Upper Airway Obstruction (HUAO).
• Children with Hypotonic Upper Airway Obstruction (HUAO): This includes those who newly diagnosed with obstructive sleep apnea (OSA). These children will undergo overnight polysomnography to determine the presence of OSA (apnea-hypopnea index \[AHI\]\>10 or AHI\>5 with nocturnal hypoxemia defined as oxygen saturation by pulse oximetry \[SpO2\] nadir \<=75%).
• All subjects require the presence of at least one symptom of OSA (such as snoring 3 or more nights per week, daytime sleepiness, or hyperactive/inattentive behaviors)
• Post adenotonsillectomy or those with contraindications to tonsillectomy.
• Tonsil size 2+ or smaller.
• Parent/caregivers willing and able to provide informed consent and child willing and able to provide assent, where appropriate.
