Cleft lip and/or palate and breathing during sleep

Summary Cleft of the lip and/or palate (CL/P) is a common defect which is associated with changes in facial structures and a smaller upper airway. As a result, infants and children with CL/P have an increased risk of sleep disordered breathing (SDB). This paper will review the anatomical and functional factors which place infants and children with CL/P at increased risk of SDB as well as review the literature which defines the magnitude of this risk. The information available on treatment of SDB in infants and children with CL/P will be presented. Finally, outstanding issues relevant to SDB in children with CL/P are discussed with direction for future research.
