Clinical investigation of the alteration in the middle ear impedance in patients with intracranial hypertension.
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.
