Conductive and Sensorineural Listening to Loss and deafnes for college kids getting ready for the USMLE.
CONDUCTIVE HEARING LOSS DEAFNESS
Conductive listening to loss invovles the a part of the ear starting from stapes to outer ear. Rinne’s Take a look at is destructive which means the bone conduction is larger than air conduction. Weber’s check lateralizes to the unhealthy ear. Absolute bone conduction shall be regular. Pure tone audiometry will present regular bone conduction and the air conduction shall be decrease than 10 decibels often known as the AB Hole. Hardly ever goes beneath 60 decibels.
Congenital causes embrace, meatal atresia, ossicular discontinuity, stapes fixation. Acquired causes embrace obstruction akin to ear wax and foriegn physique. Tympanic membrane perforation, an infection. Ossicle fixation or disruption of the ossicles. Eustuchian tube may additionally trigger.
SENSORINEURAL HEARING LOSS DEAFNESS
Sensorineural listening to loss includes cochlea and cranial nerve 8. Rinne’s check is constructive which means air conduction is larger than bone conduction. Weber’s check lateralizes to the nice ear. Absolute bone conduction in sensorineural is decreased. Pure tone audiometry in sensorineural listening to loss will present drop within the larger frequencies and there won’t be a big ab hole, however goes beneath 60 decibels. Speech discrimination shall be poor in sensorineural listening to loss.
Acquired causes embrace labyrinthitis, bodily trauma, noise trauma, acoustic neuroma, presbycusis, Meniere’s illness, medication, systemic illnesses (DM, Hypothyroidism), renal syndrome, autoimmune illnesses, blood dyscrasias and a number of sclerosis.

The healing rate of my Tinnitus and my Tuberculosis the very first time I apply and use the medicine Dr Madida sent me, it cultivated a good impression in me that it is gonna work and it did work because right now I don't longer experience Tinnitus and tuberculosis Effects anymore that I use to experience because the conditions is completely gone and my junior brother used Anosmia treatment from them too and he is cured also.
How do I calculate for the pure tone average?
Thank you. I had a radical mastoidectomy was rebuilt with bioglass. 4 yrs later certain sounds hurt my ears a kettle boiling I'd get a sudden static noise or in the car with window open. I'd always moan for ppl to speak then moan they're shouting 🤣
I do have chiari malformation too. Been told at 40 I'm young to have recruitment hearing etc so do I have conductive hearing loss because of the radical mastoidectomy or is is sensor neural becuase of the recruitment?
great video! explanation is amazing! thank you so much! just too much of "um.." hahah! was a bit difficult to focus, but nevertheless, thank you so much! <3
sir.. I have lost the hearing power in single ear.Doctor said to me you have lost 40 percent hearing power... sir is that possible to back my hearing power
Thanks 🖤🖤
My grandmother has started to get issues with her hearing, so I gave her this hearing loss treatment “Kαmkαmfο tdα” (Google it). She decided to try them and did so following the directions. It has been a few weeks and I observed that she hasn`t been asking people to repeat what they were saying, and she keeps saying her hearing is much more clear, as well. .

My dad’s hearing has been becoming worse since a couple of years ago, so I ordered the hearing loss treatment “Kαmkαmfο tdα” (Google it) for him. They didn`t immediately make him clearly hear every word spoken to him, in anyway, but I have noticed a few slight improvements within the last month. .
Back then, my right ear was deaf. Using this hearing loss treatment “Kαmkαmfο tdα” (Google it) just a couple times, and my hearing is partially back. Not perfect but helps drastically. My hearing problem is now beyond me. I won’t stop using it. .
