Eagle syndrome (also termed stylohyoid syndrome styloid syndrome, styloid-stylohyoid syndrome,〔 or styloid–carotid artery syndrome) is a rare condition caused by an elongated or deviated styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures giving rise to pain. ==Signs and symptoms== Possible symptoms include: * Otalgia (ear pain) * Dysphagia (difficulty swallowing)〔 * Foreign body sensation in throat〔 * Odynophagia (painful swallowing) * Pain on chewing〔 * Pain when turning the head (towards the affected side)〔 * Intense pain when the stylohyoid process is palpated in the wall of the pharynx〔 * Pain along the distribution of the carotid artery〔 Usually the condition is present on only one side, however rarely it may be present on both sides.〔 Two forms of eagle syndrome exists: The classic form and the vascular one. Patients with the classic "Eagle Syndrome" can present with unilateral sore throat, dysphagia, tinnitus, unilateral facial and neck pain, and otalgia. In patients with the vascular form of "Eagle syndrome", the elongated styloid process is in contact with the extracranial internal carotid artery. This can cause a compression (while turning the head) or a dissection of the carotid artery causing a transient ischemic event or a stroke. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eagle syndrome」の詳細全文を読む スポンサード リンク
