[Image analysis of arterial vessels of the internal auditory meatus during presenile and aged with hypertension and atherosclerosis].

The image analysis of the arterial vessels of the internal auditory meatus in patients with atherosclerosis and hypertension during presenility and presbycusis was done. The inner and outer diameters of the blood vessels in these patients reduced more markedly than those in the controls. There was a negative correlation between the vessel diameter and correlation age. The lumen of the vessels reduced more in patients with atherosclerosis and hypertension than those patients without these conditions. The tunica adventitia showed fibroid thickness. It suggests that the progress of the vessel changes in patients with presbycusis might be accelerated by atherosclerosis and hypertension.
