What is sensorineural hearing loss article?
Sensorineural hearing loss results from damage to the hair cells within the inner ear, the vestibulocochlear nerve, or the brain’s central processing centers. This differs from a conductive hearing loss, which results from the inability of sound waves to reach the inner ear.
What is conductive hearing?
About Conductive Hearing Loss A conductive hearing loss happens when sounds cannot get through the outer and middle ear. It may be hard to hear soft sounds. Louder sounds may be muffled. Medicine or surgery can often fix this type of hearing loss.

What causes neurosensory hearing loss?
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.
What is the medical dictionary definition of hypoacusis?
Once all eligible charts had been selected, we reviewed them for each patient’s age, sex, degree of hypoacusis, and type of prosthesis. Sudden hypoacusis is defined as a sensorineural hearing loss of rapid progression and unknown etiology that can progress to severe deafness.
How is hypoacusis related to hearing loss in children?
Hypoacusis was found as a factor present in the family, which substantiates the risk of hearing loss in children due to genetic factors, as well as delayed language that can be associated to hearing losses and unspecified neurological pathology.
What does sudden hypoacusis and facial paralysis mean?
We evaluated a 64-year-old woman who presented with long-standing and progressive left hypoacusis and facial paralysis. The term sudden hypoacusis describes a hearing loss of rapid onset and unknown origin that can progress to severe deafness.
