    en.wikipedia.org/wiki/Tympanometry

    Tympanometry is an acoustic evaluation of the condition of the middle ear [1] eardrum (tympanic membrane) and the conduction bones by creating variations of air pressure in the ear canal. Tympanometry is an objective test of middle-ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear. It is ...

    en.wikipedia.org/wiki/Conductive_hearing_loss

    Tympanometry, or acoustic immitance testing, is a simple objective test of the ability of the middle ear to transmit sound waves from the outer ear to the middle ear and to the inner ear. This test is usually abnormal with conductive hearing loss.

  6. Diagnosis of hearing loss - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_hearing_loss

    tympanometry; differential testing – the Weber, Rinne, Bing and Schwabach tests are simple manual tests of auditory function conducted with a low frequency (usually 512 Hz) tuning fork that can provide a quick indication of type of hearing loss: unilateral/bilateral, conductive, or other

  7. Eustachian tube dysfunction - Wikipedia

    en.wikipedia.org/wiki/Eustachian_tube_dysfunction

    For cases of baro-challenge induced Eustachian tube dysfunction, diagnosis usually relies on the history of the patient and their reported symptoms, as otoscopy and tympanometry is sometimes normal at normal ambient pressure. [1]

  8. Tympanosclerosis - Wikipedia

    en.wikipedia.org/wiki/Tympanosclerosis

    Tympanometry produces tympanograms which can be different when tympanosclerosis is present. [11] Computerised tomography (CT) can be used to determine if disease is present in the middle ear. [ 12 ]

    APRI (AST to platelet ratio index) is a quick serum biomarker for fibrosis assessment from Italy. This simple index is made up of routine laboratory tests. The test has not been validated by any health authorities. 50% of the results are unclassifiable. APRI may be useful for excluding significant fibrosis in hepatitis C. [citation needed]
