Lee CH, et al. - A retrospective cohort study at a US medical center was performed to analyze the relationship between transoral and awake endoscopic examination and evaluate their respective ability to prognosticate outcomes of hypoglossal nerve stimulation (HGNS). Researchers included adults individual with apnea‐hypopnea index (AHI) >15 events/hr who had undergone HGNS according to standard indications. This study included a total of 57 patients. The results of this study indicate that transoral tongue protrusion bears an inverse relationship to HGNS success and associates poorly with endoscopic tongue base movement. The findings reveal that endoscopic tongue base motion seems reflective of response to HGNS, with greater motion corresponding to greater AHI reduction.
