The craniocervical syndrome is an entity whose symptoms: vertigo, cephalea, tinnitus, facial pain, otalgia, dysphagia, pain of the carotid artery are thought to be caused by cervical factors. In the majority of cases the cranio-cervical syndrome is caused by a spondylarthrogenic segmental dysfunction whose pathophysiology is explained. In the pathogenesis lesions of the joints of the skull which may be responsible for pain and dysfunction in the segmental areas are of great importance. The neurology of the joints of the skull, as well as the pathological mechanisms of spondylarthrogenic disturbances, responsible for the different kinds of dysfunction of the equilibrium and for cephalea are discussed. The pathophysiological basis of manual diagnosis is explained; also the radiological findings of the upper cervical vertebral column are principally discussed. A short review of therapeutic recommendations is given.
