title: Clinical investigation of the alteration in the middle ear impedance in patients with intracranial hypertension.
abstract: Marked pulsation occurring during middle ear impedance measurements may be caused by an intracranial hypertension sydnrome, with pulsations being transmitted to the middle ear by a variety of preformed natural pathways. Impedancemetry is a useful technique for diagnosing and following the syndrome.
