Tinnitus
From WikiLectures
As tinnitus (ringing in the ears) we refer to auditory sensations for which there is no sound source in the external environment.
Subjective Tinnitus[edit | edit source]
Auditory perception is not linked to real physical sound, it is perceived only by the patient.
- Usually pure tones, noises or sounds:
- Conductive hearing loss is usally accompanied by humming and buzzing.
- Perceptual hearing loss is most often accompanied by whistling, buzzing, ringing or hissing.
- (Sometimes also in lesions of the middle ear otosclerosis, tympansclerosis).
- Tinnitus may be the first symptom of a vestibular schwannoma.
Objective Tinnitus[edit | edit source]
Objective tinnitus is less common and is caused by an actual sound source near the auditory system, the sound is not only heard by the patient.
- Blood flow in a vascular malformation (arteriovenous shunts), stenosis, aneurysm or in a tumor can be influenced by compressing the supply artery.
- More rarely, the contraction of the musles of the middle ear has the character of peeling or humming.
Anamnesis[edit | edit source]
We describe symmetry/lateralization, intensity, character, pitch, duration and affectability.
