[Compression of the external carotid artery. An anatomical finding to Eagle's syndrome (author's transl)].

An anatomical finding to Eagle's styloid process-carotid artery syndrome is presented. The left external carotid artery of a 64-year-old male is compressed by an anomalous styloid process and by the tendon of the stylohyoid muscle. Symptoms caused by anomality of the styloid process are reported by means of literature. The histological examination of the vessel wall in the level, where it is compressed, reveals typical characteristics of early arteriosclerosis.
