Abstract
Eagle's syndrome, also known as styloid artery syndrome, is a symptom complex associated with elongation of the temporal styloid process or calcification of the stylohyoid ligament. There is high anatomical variability in the angulation and length of the styloid process which gives rise to anatomical relationships with the internal carotid artery and cranial nerves 5, 7, 9, and 10. The vascular form of Eagle's syndrome, a sequela of the relationship of the styloid process and extra-cranial internal carotid artery, is associated with vascular occlusive neurological symptoms. Similarly the classic form of Eagle's syndrome, a sequela of the relationship of the styloid process and cranial nerves 5, 7, 9, and 10, is associated with cervicalgia, odynophagia, dysphagia, and otalgia. Anatomical knowledge is of paramount importance in the diagnosis and management of Eagle's syndrome and would benefit students and surgical trainees encountering this condition. A literature review was performed evaluating the anatomical basis of Eagle's syndrome, anatomical variation in styloid length, and the non-invasive and surgical management of Eagle's syndrome.
