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