Eagle syndrome is characterized by the sensation of a foreign body in the throat, odynophagia, dysphagia, and craniofacial or cervical pain due to an elongated styloid process. Some reports have indicated that an elongated styloid process is one of the causes of carotid artery dissection (CAD). This is the first report describing the anesthetic management of Eagle syndrome complicated by CAD. Careful intratracheal intubation and neurological monitoring are important to prevent intraoperative neurologic deficits. In addition, attention must be paid to postoperative complications such as airway obstruction.
