The inner ear includes sensory organs for balance and hearing. When the inner ear is inflamed, vertigo is a common symptom. Other symptoms in adults include pain and drainage from ear or problems with hearing. [8] Symptoms in children can include excessive crying, touching at ears, drainage, and fever. [8]
If wax in the ear canal obscures a clear view of the eardrum it should be removed using a blunt cerumen curette or a wire loop. An upset young child's crying can cause the eardrum to look inflamed due to distension of the small blood vessels on it, mimicking the redness associated with otitis media. [25]
While the disease is fatal, the age of onset is a key factor, as infants have a typical life expectancy of 2–8 years, while adults typically live more than a decade after onset. Treatment options are limited, although hematopoietic stem cell transplantations using bone marrow or cord blood seem to help in certain leukodystrophy types, while ...
External otitis, swimmer's ear [1] A moderate case of otitis externa. There is narrowing of the ear channel, with a small amount of exudate and swelling of the outer ear. Specialty: Otorhinolaryngology: Symptoms: Ear pain, swelling of the ear canal, decreased hearing, [2] difficulty chewing: Types: Acute, chronic [2] Causes
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.
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]
Life expectancy development in some big countries of the world since 1960 Life expectancy at birth, measured by region, between 1950 and 2050 Life expectancy by world region, from 1770 to 2018 Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age.
Most causes of conductive hearing loss can be identified by examination but if it is important to image the bones of the middle ear or inner ear then a CT scan is required. CT scan is useful in cases of congenital conductive hearing loss, chronic suppurative otitis media or cholesteatoma, ossicular damage or discontinuity, otosclerosis and ...
