management of a CICO event
emergency front of neck airway with scalpel cricothyroidotomy
what is SALT
speech and language therapy
what is a hearing aid
a sound amplifier
what is the benefit of an open behind the ear hearing aid
does not completely occlude the ear canal, so patients do not lose the natural sound from the blockage of the canal and their canals do not become moist due to occlusion
how does a telecoil work
causes distortions in a magnetic field which are picked up by the users hearing aid and then converted back into sound
when are bone anchored hearing aids used
in patients with recurrent discharge or absence/stenosis of the ear canal
indication for cochlear implant
profound sensorineural hearing loss where conventional hearing aids are of little help
what does audiometry measure
a persons ability to measure different sounds, pitches and frequencies
aim of audiometry
to find a patients hearing threshold
what is hearing threshold
the quietest sound that an individual can hear across a range of different frequencies
what does pure tone audiometry provide information on
the type of hearing loss
when does masking occur
when hearing acuity of the ears is very different
when is tympanometry used
to test the condition of the middle ear by creating variations of pressure in the ear canal
what can tympanometry be useful in diagnosis
otitis media - shows the presence of a middle ear effusion
what can happen to the measured canal volume in a patient with perforation
volume can be large
when is type B tympanogram often seen
in children with fluid behind their eardrum
when is type C tympanogram seen

when is type As tympanogram seen
