Diagnostic Approach to Tinnitus
I've found a comprehensive article about Tinnitus diagnostic on a
level of doctor of general practice. Few accents: vibratory tinnitus:
vibrations from adjacent tissues are transfered to cochlea. pulsating
t. arises from vascular disorders: aneurysms, acquired arterio-venous
shunts Pulsatile t., unilateral t. and t. associated with other
unilateral ear problems speak for an organic cause. Subjective t.
(heard by patients only) mostly arises from the same condition as the
hearing loss: eardrum perforation, noise exposion... Some other
causes: Psychologic, Anemia, Thyroid disorder, Drugs: Aspirin,
Gentamycin, Furosemid. Lead, mercury. Multiple sclerosis, nerve
tumors. Objective t. (heard with stethoscope): Patients tipically have
vascular abnormality, neurologic disease or eustahyan tube
dysfunction. Diagnostic: otologic examination, sound tests,
audiometry. Blood tests (minerals, cells, hormones), MRI (tumors)
Notice: *Not all subjective tinnitus have a psychologic cause.* Read
