Questions and Mark scheme
Version: Final
, advantages of ITE - ✔✔small and therefore more acceptable, better mic placement that BTE, more secure fit,
easy to insert and remove, and to adjust the volume
disadvantages of ITE - ✔✔not generally a good option for children, Dont consider for kids until they are done
maturing 10-12 and their ears stop changing and growing
advantages of ITC - ✔✔small and even less conspicuous and therefore more cosmetically appealing than ITE,
portion of the concha is left free, allowing for natural resonance and diffraction effects, less difficulty with
feedback when using the telephone, compared to ITE's, less wind noise due to more deeply seated mic
disadvantages of ITC - ✔✔may not be enough gain and output, tcoil is not available in all ITC's, smaller battery
size, difficulty for some people to manage, size and circuitry (if patients ear is very small there may not be
enough room to place the circuity in an ITC shell), more expensive than ITE
CIC - ✔✔Completely in the canal, cannot be seen
advantages of CIC - ✔✔cosmetically appealing, inc output because of deep canal placement, occlusion effect is
dec, easy to insert and remove, reduction in wind noise since mic is in ear canal, dec feedback
disadvantages of CIC - ✔✔limited circuits and adjustments available, small battery require good dexterity,
more expensive than ITC, Tcoil may not be available
bone conduction - ✔✔for patients who have atresia or a lot of ear problems in the outer ear space, severe
microtia, born without ossicles forming, single sided deafness, chlosteotoma, OR with unilateral HL- no hearing
all at all in one ear, BC sound travels to opposite ear's cochlea, end result = binaural hearing
two types of bone conduction - ✔✔traditional and implantable
traditional bone conduction - ✔✔a vibrator is placed behind the ear and over the mastoid rarely used
implantable - ✔✔BAHA
BAHA - ✔✔Device is implanted surgically behind the ear in the mastoid, used for conductive and mixed
hearing losses with congenital atresia, or longstanding middle ear dysfunction
Vibrate across the skull to the good cochlea on the other side to get localization here more popular with single
sided deafness (from chronic middle ear infection or nonforming)
Takes a 13 or 312 battery
Implantable NOT cochlear implant
Used with single sided deafness
best hearing aid - ✔✔aid the patient will wear effectively and fit their lifestyle
different types of batteries - ✔✔10, 312, 13, 675
