Dr. Zaghi graduated from Harvard Medical School, completed his residency in ENT (Otolaryngology- Head and Neck Surgery) at UCLA, and Sleep Surgery Fellowship at Stanford University. The focus of his sub-specialty training is on the comprehensive treatment of nasal obstruction, snoring, and obstructive sleep apnea. He is very active in clinical research relating to sleep-disordered breathing with over 60+ peer-reviewed research publications in the fields of neuroscience, head and neck surgery, and sleep-disordered breathing.
Dr. Zaghi is particularly interested in studying the impact of tethered-oral tissues (such as tongue-tie) and oral myofascial dysfunction on maxillofacial development, upper airway resistance syndrome, and obstructive sleep apnea. He is an invited lecturer, author, and journal reviewer for topics relating to the diagnosis and management of sleep-disordered breathing and tongue-tie disorders.
Research interests include study design, literature review, and statistical analysis. Special interest in collaborative and multidisciplinary research projects relating to airway and breathing disorders, obstructive sleep apnea, nasal obstruction, upper airway resistance syndrome, pediatric sleep disorders, myofunctional therapy, frenuloplasty, facial and airway development, and maxillofacial reconstructive surgery.
