Clinical InformationClinical

  • Correction of Hearing Impairment

    procedures for correcting hearing disorders.
  • Deafness

    a general term for the complete loss of the ability to hear from both ears.
  • Hearing Loss

    a general term for the complete or partial loss of the ability to hear from one or both ears.
  • Hearing Loss, Bilateral

    partial hearing loss in both ears.
  • Hearing Loss, Central

    hearing loss due to disease of the auditory pathways (in the central nervous system) which originate in the cochlear nuclei of the pons and then ascend bilaterally to the midbrain, the thalamus, and then the auditory cortex in the temporal lobe. bilateral lesions of the auditory pathways are usually required to cause central hearing loss. cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. unilateral brain stem lesions involving the cochlear nuclei may result in unilateral hearing loss.
  • Hearing Loss, Conductive

    hearing loss due to interference with the mechanical reception or amplification of sound to the cochlea. the interference is in the outer or middle ear involving the ear canal; tympanic membrane; or ear ossicles.
  • Hearing Loss, Functional

    hearing loss without a physical basis. often observed in patients with psychological or behavioral disorders.
  • Hearing Loss, Hidden

    hearing loss that is difficult to diagnose by standard hearing tests as it most often pertains to difficulties in hearing only in certain situations such as in noisy environments.
  • Hearing Loss, High-Frequency

    hearing loss in frequencies above 1000 hertz.
  • Hearing Loss, Mixed Conductive-Sensorineural

    hearing loss due to damage or impairment of both the conductive elements (hearing loss, conductive) and the sensorineural elements (hearing loss, sensorineural) of the ear.
  • Hearing Loss, Noise-Induced

    hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 db. the hearing loss is often in the frequency range 4000-6000 hertz.
  • Hearing Loss, Sensorineural

    hearing loss resulting from damage to the cochlea and the sensorineural elements which lie internally beyond the oval and round windows. these elements include the auditory nerve and its connections in the brainstem.
  • Hearing Loss, Sudden

    sensorineural hearing loss which develops suddenly over a period of hours or a few days. it varies in severity from mild to total deafness. sudden deafness can be due to head trauma, vascular diseases, infections, or can appear without obvious cause or warning.
  • Hearing Loss, Unilateral

    partial or complete hearing loss in one ear.
  • Retrocochlear Diseases

    pathological processes involving the vestibulocochlear nerve; brainstem; or central nervous system. when hearing loss is due to retrocochlear pathology, it is called retrocochlear hearing loss.
  • Hearing Disorders

    conditions that impair the transmission of auditory impulses and information from the level of the ear to the temporal cortices, including the sensorineural pathways.
  • Conductive Hearing Loss of Combined Sites|Conductive hearing loss of combined sites

    conductive hear loss presenting across multiple sites in the ear.
  • Have Problems with Hearing Loss that Make Me Angry Question|Have Problems with Hearing Loss that Make Me Angry|I have problems with my hearing that make me angry

    a question about whether an individual has or had problems with their hearing that makes them angry.
  • Hearing Loss Makes Me Angry Question|Does your hearing make you angry|Hearing Loss Makes Me Angry

    a question about whether an individual's hearing loss makes them angry.
  • Hearing Loss Makes Me Feel Different from Everyone Else Question|Do you feel different from others because of your hearing|Does your hearing loss make you feel different from everyone else|Hearing Loss Makes Me Feel Different from Everyone Else

  • Worry About Hearing Loss Getting Worse Question|Do you worry about your hearing loss getting worse|I worry about my hearing loss getting worse|Worry About Hearing Loss Getting Worse

    a question about whether an individual worries about their hearing loss getting worse.
  • Central Hearing Loss

    hearing loss resulting from disorders of the central nervous system auditory pathways.
  • Complete Deafness|Total Deafness|Total Hearing Loss

    total inability to hear sounds in one or both ears.
  • Complete Neonatal Hearing Loss

    complete loss of the ability to detect or understand sounds present in an infant within its first month after birth.
  • Conductive Hearing Loss|Conductive Deafness

    hearing loss caused by impaired transmission of signals from the external auditory canal or middle ear to the cochlea.
  • DLX5 wt Allele|Distal-Less Homeo Box 5 Gene|Distal-Less Homeobox 5 wt Allele|SHFM1D|Split Hand/Foot Malformation Type 1 With Sensorineural Hearing Loss Gene

    human dlx5 wild-type allele is located in the vicinity of 7q21.3 and is approximately 5 kb in length. this allele, which encodes homeobox protein dlx-5, plays a role in transcriptional activation that is essential for osteoblast differentiation. mutation of the gene is associated with split-hand/foot malformation 1 with sensorineural hearing loss.
  • Functional Hearing Loss

    hearing loss in the absence of auditory system pathology.
  • Have Problems with Hearing Loss that Make Me Angry|I have problems with my hearing that make me angry

    a question about whether an individual has or had problems with their hearing that makes them angry.

Patient EducationClinical

Hearing Disorders and Deafness

It's frustrating to be unable to hear well enough to enjoy talking with friends or family. Hearing disorders make it hard, but not impossible, to hear. They can often be helped. Deafness can keep you from hearing sound at all.
