==Postnatal Hearing==<br />
First, look through the adult ear structures and identify their developmental origins.<br />

'''Auditory Tube''' (Eustachian, otopharyngeal or pharyngotympanic tube)<br />
<br />
Connects middle ear cavity to nasopharynx portion of pharynx. Tube is normally closed and opened by muscles.<br />
<br />
# Ventilation - pressure equalization in the middle ear<br />
# Clearance - allow fluid drainage from the middle ear<br />
<br />
Newborn to adult auditory tube<br />
<br />
'''Birth'''<br />
* shorter (17-18 mm), narrower and runs almost horizontal<br />
* Tube is opened by a single muscle, tensor palati muscle<br />
'''Adult'''<br />
* longer (twice as long), wider and runs at approximately 45 degrees to the horizontal.<br />
* Tube is opened by two separate muscles, tensor palati and levator palati<br />

==Hearing Testing==<br />
[[File:Newborn_hearing_test.jpg|thumb|Newborn hearing test]]<br />
<br />
Abnormalities in neonatal hearing can impact upon development of the nervous system and developmental learning milestones, early detection is therefore key.<br />
<br />
The incidence of significant permanent hearing loss is approximately 1-3/1000 newborns. Neonatal hearing screening is carried out in several countries including the USA, UK and in Australia. In NSW the Statewide Infant Screening Hearing Program (SWISH) was introduced in 2002.<br />
<br />
There is also a general guide giving a timetable for a number of simple responses that a neonate should make if hearing has developed normally (More? Neonatal Hearing Check List).<br />
<br />
The two major forms of hearing loss are conductive and sensorineural.<br />
<br />
State Wide Infant Screening Hearing Program (SWISH) a newborn hearing testing program using an automated auditory response technology (AABR). Program was introduced in NSW Australia in 2002 across 17 area health service coordinators. It is thought that in NSW 86,000 births/year = 86-172 babies potentially born with significant permanent hearing loss.<br />
<br />
Automated Auditory Brainstem Response (AABR) uses a stimulus which is delivered through earphones and detected by scalp electrodes. The test takes between 8 to 20 minutes and has a sensitivity 96-99%.<br />
