Complex Sleep Apnea Program

The Complex Sleep Apnea Pro485913979gram cares for children with complex health issues who have difficulties with breathing during sleep, despite traditional management for obstructive sleep apnea.

To help these children, the program uses the latest diagnostic tools and therapies, along with a coordinated care approach by sleep specialists from Respiratory Medicine (sleep medicine), Otolaryngology (sleep surgery) and Plastic Surgery (craniofacial surgery).

Daniel Lesser, M.D., (Respiratory Medicine) Rakesh Bhattacharjee, M.D., (Respiratory Medicine/Sleep Medicine) Javan Nation, M.D., (Otolaryngology) and Samuel Lance, M.D., (Plastic Craniofacial Surgery) collaborate to create a management plan that considers the unique features of each child’s sleep disorder. Drs. Lesser and Bhattacharjee assess the child’s sleep study, evaluate candidacy for positive airway pressure therapy and identify the need to further evaluate the child or treat associated illnesses.

Dr. Nation provides expertise in anatomic assessment of the upper airway soft tissue using in-office laryngoscopy, as well as sleep endoscopy and use of cine-airway MRI. Dr Lance assesses the upper airway through the evaluation of the mid-face, mandibular and oral cavity bony structure. Both Drs. Nation and Lance have special expertise in cutting-edge surgical procedures that improve sleep-related breathing disorders, which have been successfully performed on patients in our program.
