Sleep apnea is characterized by repetitive breathing pauses during sleep.  In children, sleep apnea results in sleep disruption, poor quality-of-life and can have negative neurodevelopmental, cardiovascular, and behavioral consequences.  Adenotonsillectomy is the first line treatment for children with sleep apnea. However, up to 40% of children will have persistent sleep apnea after adenotonsillectomy, making this a challenging problem to treat. Dr. Kirkham’s research will focus on optimizing treatment outcomes for children with sleep apnea.
