<p>Background and Objectives : Ischemic stroke is a well-known disease occurring in patients that is variously caused by hypertension, diabetes metabolism, hyperlipidemia, alcohol, smoking, etc. However, the hyoid bone has not been recognized among the possible causes. Materials and Methods : Two patients who presented with ischemic stroke due to mechanical stimulation of the hyoid bone were included in this study. One patient (69 years old, male) had a recurrent brain infarction, and the other (71 years old, male) suffered from hypertension and hypercholesterolemia. Both patients were diagnosed with ischemic stroke caused by mechanical stimulation of the hyoid bone, based on a combination of several imaging studies such as neck ultrasound, computed tomography, computed tomographic angiography, magnetic resonance imaging and angiography. Simultaneously with surgical treatment by a neurosurgeon, the greater horn of hyoid and superior cornu of the thyroid cartilage on the affected side were resected by otolaryngologists. In both cases, the patients had no new cerebral infarctions postoperatively. Conclusions : Hyoid bone-related carotid artery injury is a rare etiology of a stroke which is unknown to many doctors. Carotid artery impingement with compression by the hyoid bone seems to be extremely uncommon and a diagnosis of exclusion. Imaging studies with provocative maneuvers are helpful for making a diagnosis.</p>
