What type of deafness is caused by meningitis?

What type of deafness is caused by meningitis?

Hearing loss from meningitis and septicaemia is described as sensorineural hearing loss and this type of hearing loss is permanent. If a child has hearing loss after meningitis there is a risk of excess bone growth in the cochlea (called ossification) in the weeks and months after recovery.

Can meningitis cause hearing impairment?

Bacterial meningitis is the single most important cause of acquired sensorineural hearing impairment in children and every attempt should be made to assess the child’s hearing as soon after recovery as possible.

Does bacterial meningitis cause sensorineural hearing loss?

Bacterial meningitis is the most common etiology for acquired hearing loss. In addition, 5% to 35% of patients with bacterial meningitis will develop permanent sensorineural hearing loss, and profound bilateral hearing loss will occur in up to 4% of patients.

Can bacterial infections cause hearing loss?

Also known as otitis media, a middle ear infection occurs when bacteria or a virus causes inflammation and fluid buildup in the area behind the eardrum. This type of middle ear infection can lead to temporary hearing loss.

Why does meningitis cause amputation?

One deadly complication of meningococcal infection is purpura fulminans where blood clots develop in the bloodstream. These block small blood vessels and cause tissue to die. This is why patients with meningococcal septicaemia lose fingers, toes and entire limbs. Clotting can also damage vital organs.

What is nerve deafness caused by?

Sensorineural hearing loss (SNHL) is caused by damage to the structures in your inner ear or your auditory nerve. It is the cause of more than 90 percentof hearing loss in adults. Common causes of SNHL include exposure to loud noises, genetic factors, or the natural aging process.

How long does it take for meningitis to cause hearing loss?

What organisms cause sensorineural deafness?

The viruses that are certainly involved in the etiology of progressive sensorineural hearing loss are Cytomegalovirus and Rubella virus.
