Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system .
Clinical features are similar in both types but appear milder in Morquio Type B. Onset is between ages 1 and 3. Neurological complications include spinal nerve and nerve root compression resulting from extreme, progressive skeletal changes, particularly in the ribs and chest; conductive and/or neurosensitive loss of hearing and clouded corneas.
Sensorineural hearing loss: Conductive hearing loss: Anatomical site: Inner ear, cranial nerve VIII, or central processing centers Middle ear (ossicular chain), tympanic membrane, or external ear: Weber test: Sound localizes to normal ear in unilateral SNHL Sound localizes to affected ear (ear with conductive loss) in unilateral cases Rinne test
Key Takeaways: Common hearing loss symptoms include: turning up the volume, struggling in background noise, asking for repetition, or even withdrawing from social settings due to frustration.
The Rinne test (/ ˈ r ɪ n ə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss. [2]
The most common type of congenital hearing loss in developed countries is DFNB1, also known as connexin 26 deafness or GJB2-related deafness. The most common dominant syndromic forms of hearing loss include Stickler syndrome and Waardenburg syndrome. The most common recessive syndromic forms of hearing loss are Pendred syndrome and Usher syndrome.

The hearing loss and ringing in the ears can become constant over time. [4] The cause of Ménière's disease is unclear, but likely involves both genetic and environmental factors. [1] [3] A number of theories exist for why it occurs, including constrictions in blood vessels, viral infections, and autoimmune reactions. [3]
