Additional Study Information: We are currently looking for adult patients who have undergone successful treatment of their obstructive sleep apnea with a hypoglossal nerve stimulator implant (i.e. Inspire therapy). Participants should be willing to participate in at-home sleep studies and come to Columbia University Irving Medical Center for at least 2 study visits. Participants will receive gift cards to cover their transportation to and from study visits as well as for participation. For more information and to see if you may be eligible, please email: otosleepresearch@cumc.columbia.edu.
