    After an otoscopy (examination of the ear with an otoscope) to ensure that the path to the eardrum is clear and there is no perforation, the test is performed by inserting the tympanometer probe in the ear canal. The instrument changes the pressure in the ear, generates a pure tone, and measures the eardrum responses to the sound at different ...

    Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.

  8. Sensorineural hearing loss - Wikipedia

    en.wikipedia.org/wiki/Sensorineural_hearing_loss

    There are both external causes of damage, including infection, and ototoxic drugs, as well as intrinsic causes, including genetic mutations. A common cause or exacerbating factor in SNHL is prolonged exposure to environmental noise, or noise-induced hearing loss. Exposure to a single very loud noise such as a gun shot or bomb blast can cause ...

    Conductive hearing loss developing during childhood is usually due to otitis media with effusion and may present with speech and language delay or difficulty hearing. Later onset of conductive hearing loss may have an obvious cause such as an ear infection, trauma or upper respiratory tract infection or may have an insidious onset related to ...
