types of hearing loss
conductive, sensorineural, mixed, and non-organic
parts of conductive mechanism
outer and middle ear
common causes of conductive hearing loss
ear infection (otitis media) and wax buildup
inflammation of middle ear. also called ear infection.
chronic perforation. it's a mass that starts to form on the ossicles and starts to erode them.
affects middle ear. spongey, boney growth. fixates the stapes. one of the only disorders that can cause loss in inner/outer ears for one condition. common in women.
small pinna/auricle. congenital.
obstruction to external auditory canal. congenital.
no pinna/auricle. congenital
inflammation of outer ear. ex. swimmers ear.
ossicles not working together. therefore vibration can't transmit. could be caused by cholestiotoma, head trauma or could be congenital.
change in pressure too quickly for Eustachian tube to adjust. ex. scuba diving.
large tumor in middle ear. can cause ringing in ears that sounds like your heart beat.
scar tissue that can form on eardrum secondary to ear infection. may not cause hearing loss.
sensorineural hearing loss
affects our ability to process sound (unlike conductive hearing loss). usually a cochlear problem. mild-profound severity. reduced frequency selectivity. reduction in sensitivity of cochlea.
abnormal sensitivity of cochlea within people with hearing loss.
causes of SNHL
genetics-syndromic or non-syndromic. noise exposure-acoustic trauma, occupational noise exposure. age-presbycusis.
flu like virus. hard to tell if you have it, most people get it at least once but if you get it while pregnant It can cause major hearing problems in the child. congenital. SNHL
the virus and meds to treat the virus can cause hearing problems. congenital. SNHL
publicity said that vaccination for this and polio etc. might cause autism so stopped vaccinating. congenital. SNHL
supposedly cat poop can cause problems for the baby if the mom is dealing with it during pregnancy. congenital. SNHL
typically around age 2. some children actually do better because cochlear implants are put in sooner than a child with regular hearing loss. acquired. SNHL
can cause unilateral hearing loss. acquired. SNHL
group of symptoms occur in episodes. excessive endolymph in cochlea.
symptoms involved with Meniere's disease
low frequency tinnitus, low frequency SNHL, pressure in ear and vertigo.
experience some symptoms of Meniere's disease rather than all of them.
medication you've taken that's toxic for your ear. the medication is often life saving. problems can occur by either you taking them or if your mom is pregnant with you.
we have no idea what caused the SNHL
retrocochlear hearing disorder
beyond level of cochlea. originates in neural structure of peripheral or central auditory nervous system. changes may be subtle. most profound effect- ability to understand speech is compromised.
clinical features of retrocochlear
auditory adaptation, decay of acoustic stapedius reflex, don't experience recruitment. hard to perceive speech in noise.
multiple tumors causing retrocochlear.
neural disorders causing retrocochlear
cochlear neuritis and diabetic cranial neuropathy
inflammation of auditory nerve
diabetic cranial neuropathy
problem with blood supply to auditory system
brain stem disorder-tumor.
