[Stylohyoid syndrome. Apropos of a case].

Authors report a case of stylohyoid syndrome (Eagle's syndrome) caused by the curvation of the shaft of the styloid process that impigies on the internal carotid artery. Stylohyoid syndrome should be considered when inspecting the differents diagnosis of facial pain. Diagnostic work up is made from transpharyngeal styloid process palpation and X ray examinations. Amputation of the styloid process by a pharyngeal approach gives good results.
