Talking Sleep Season 5
Predicting HGNS Treatment Success
Dr. Raj Dedhia, guest
In today’s episode of Talking Sleep, Dr. Raj Dedhia joins us to talk about hypoglossal nerve stimulation, which was first approved by the FDA in 2014 to treat a subset of patients with moderate to severe obstructive sleep apnea. Now, nearly a decade later, the treatment has evolved, and we have a better understanding of its nuances. Visualizing the airway during sleep endoscopy is a key element in patient selection; however, Dr. Dedhia explains that there are other ways to predict treatment success.
Dr. Raj Dedhia is an associate professor and director of sleep surgery and the CPAP Alternatives Clinic at the University of Pennsylvania. He is board-certified in both sleep medicine and otolaryngology. He has a unique background having completed an accredited fellowship in sleep medicine and surgery at the University of Washington, a residency in otolaryngology/head & neck surgery at the University of Pittsburgh Medical Center, and a master’s in clinical research from the University of Pittsburgh. Dr. Dedhia’s current research includes upper airway pathophysiology in sleep-disordered breathing as well as the cardiovascular effects of sleep-disordered breathing.
