Attending Physician

Dr. Cielo conducted clinical and translational research related to the mechanisms and effects of obstructive sleep apnea in children, with a specific focus on infant populations, children with craniofacial conditions, and the use of MRI and other imaging modalities to understand structural contributors to obstructive sleep apnea in children.

Obstructive sleep apnea syndrome (OSAS) is common in children and can have important behavioral, neurocognitive, inflammatory, and cardiovascular consequences if left untreated. Some infants and children, particularly those with craniofacial abnormalities, are at increased risk for OSAS, but the evaluation and management of these patients can be challenging. Dr. Cielo’s research program focuses on understanding the causes of OSA in infants and children with a variety of complex medical conditions and optimizing treatment strategies for these patients.

His current studies use advanced MRI techniques to evaluate the structural contributors to OSA in infants with micrognathia and children with Beckwith-Wiedemann syndrome, and how craniofacial surgery affects the upper airway anatomy and OSA. In infants with micrognathia, Dr. Cielo and his colleagues are also studying the correlation between feeding and growth with OSA. Additional research studies are evaluating the benefits and challenges of using continuous positive airway pressure in infants and children with a variety of different medical conditions who have OSA.

Dr. Cielo’s research is affiliated with the CHOP Sleep Center research program, as well as the neonatal craniofacial program and the Beckwith-Wiedemann program.
