The purpose of this article is to increase awareness of the radiographic appearances of the hypoglossal nerve stimulator (HNS) device in the head and neck region. A 55-year-old man, unresponsive to various medical therapies, had an implanted HNS lead and ribbon electrodes that appeared as hyperdense structures on radiographic and cone beam computed tomography (CBCT) images. Clinicians should be able to recognize the presence of neurostimulator devices used for chronic sleep apnea management through radiologic examinations of the head and neck.
BackgroundThe hypoglossal nerve stimulator (HNS) device has been employed in some patients with refractory or unsatisfactory outcomes to chronic obstructive sleep apnea management. The objective of this article is to increase recognition of the radiologic appearances of this device within the head and neck region, as seen on extraoral radiographic and cone beam computed tomography (CBCT) images.Clinical PresentationA 55-year-old man, refractory to a multitude of apneic medical therapies, underwent a series of preorthognathic radiologic studies. Notably, an implanted HNS lead and ribbon electrodes appeared as hyperdense structures on the panoramic radiograph, lateral cephalogram, and CBCT scan.ConclusionThis article provides various radiologic views of the primary components of an HNS. Clinicians should be able to recognize the presence of neurostimulator devices used for management of chronic sleep apnea within the radiologic field of view of examinations of the head and neck.
