50flU3Tt2NU, Conductive and Sensorineural Hearing Loss Deafness for USMLE, Conductive and Sensorineural Hearing Loss and deafnes for students preparing for the USMLE.

CONDUCTIVE HEARING LOSS DEAFNESS
Conductive hearing loss invovles the part of the ear ranging from stapes to outer ear. Rinne’s Test is negative meaning the bone conduction is greater than air conduction. Weber’s test lateralizes to the bad ear. Absolute bone conduction will be normal. Pure tone audiometry will show normal bone conduction and the air conduction will be lower than 10 decibels known as the AB Gap. Rarely goes below 60 decibels.

Congenital causes include, meatal atresia, ossicular discontinuity, stapes fixation. Acquired causes include obstruction such as ear wax and foriegn body. Tympanic membrane perforation, infection. Ossicle fixation or disruption of the ossicles. Eustuchian tube may also cause.

SENSORINEURAL HEARING LOSS DEAFNESS
Sensorineural hearing loss involves cochlea and cranial nerve 8. Rinne’s test is positive meaning air conduction is greater than bone conduction. Weber’s test lateralizes to the good ear. Absolute bone conduction in sensorineural is decreased. Pure tone audiometry in sensorineural hearing loss will show drop in the higher frequencies and there will not be a large ab gap, but goes below 60 decibels. Speech discrimination will be poor in sensorineural hearing loss.

Acquired causes include labyrinthitis, physical trauma, noise trauma, acoustic neuroma, presbycusis, Meniere’s disease, drugs, systemic diseases (DM, Hypothyroidism), renal syndrome, autoimmune diseases, blood dyscrasias and multiple sclerosis.,

There are many myths about hearing loss. How many do you believe?

Never miss a new safety video! Subscribe: http://www.youtube.com/subscription_center?add_user=safetymemos

This safety training video covers 5 myths about hearing loss and the true facts that can save you from permanent ear damage. We also talk about several sources of hazardous noise. Protect your hearing, and it will protect you!

Hazardous noise is all around us, and according to many researchers, getting worse every year. Do you work in an area where you are exposed to dangerous noise levels above 85 decibels? How do you protect yourself?

Did you know that once your ears are damaged, they will never go back to normal? Protect yourself, your co-workers, and your family by learning about what causes hearing damage, and then take the proper steps toward protection of this valuable personal asset!

It does not matter where you work or live, there are noise hazards almost everywhere. Establish hearing protection as part of your daily safety culture. This video applies to any home or workplace, including hospitals, warehouses, retail, manufacturing, offices – anywhere.

What hearing loss sounds like – This video you will hear a number of sound simulations – via a conversation with Fred, Daphne, Scooby Doo, Shaggy and some monster – courtesy of Scooby Doo/Warner Brothers. This video will give you an insight into what it is like living with hearing loss.

Many people, especially those with age-related hearing loss, lose the ability to detect high-frequency sounds. Because consonants are typically higher-pitched than vowels, the loss of high frequencies can make it difficult to tell consonant sounds apart. As a result, speech sounds muddy — in some cases, almost beyond comprehension.
What hearing loss sounds like

If your hearing is normal, this means you can understand speech in a noisy environment and no amplification or hearing aids are needed.

Mild hearing loss means you may be having difficulty understanding speech in noisy environments. It may also mean that you require a higher volume level when watching the television or listening to the stereo. Because of this, family members are often the first to notice. Adults will benefit from In-the-Ear or Mini-Behind the Ear hearing aids.

With moderate hearing loss you will frequently have difficulty understanding speech in noisy environments including the telephone, television and listening to speakers at public gatherings. You may find that you are regularly asking people to repeat themselves and you get frustrated because you are missing what they are saying. People may also tell you that you speak too loudly in conversations. Adults will see the greatest benefit from Mini-Behind the Ear hearing aids.

If you have severe hearing loss, This means you are having significant difficulty hearing during most types of communication and you may start avoiding noisy places where you know you will miss much of the conversation. You still may have communications difficulties with Behind the Ear hearing aids.

And if your hearing loss is profound, your loss will be in the 90-120 decibel range. At this level you are having major communication problems in all situations. Profound hearing loss typically requires visual assistance while communicating, such as lip-reading or sign language. You will still have communication difficulties with hearing aids but fullsize, super-powerful, behind the ear hearing aids will be very useful for obtaining cues and environmental sounds.,
