Abstract

The successful introduction of Doppler and Color-Coded Doppler Sonography (CCDS) in the field of Otorhinolaryngology has improved the diagnostic sonographic value for several diseases of the head and neck region, e. g. in hemangiomas and vascular malformations. The diagnostic value of CCDS for examination of the extracranial brain supplying vessels in combination with neuro-otologic disorders is still under controversial discussion. We investigated the diagnostic CCDS findings for 215 patients suffering from different neuro-otologic disorders. All patients were classified into 4 groups according to the different disorder entity (sudden deafness, tinnitus, vestibular neuropathy, combined diagnosis). The frequency of pathologic CCDS findings was correlated with the different groups using sonographic parameters such as atherosclerosis, stenosis and intima-media thickness. Classification of the disorder entities led to the following distribution: Sudden deafness group (85 patients; 40 %), Tinnitus group (44 patients; 20 %), Vestibular neuropathy group (41 patients; 19 %), Combined diagnosis group (45 patients; 21 %). Sonographic evaluation of atherosclerosis was possible in 76 cases (35 %), changes of the intima-media thickness wer...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
