Properly functioning of eustachian tube is related to the ventilation of the middle
ear cavity that is must in avoiding the development of a negative
pressure gradient due to middle ear mucosal gas absorption.If ETD is not dealt there can be a formation of membrane that causes retract in ear and loss of defense( in form of glandular secretions) can also occur. In this case nasopharyngeal pathogens can causes different ear issues. But different studies have shown that therapies are not much reliable in this case. For further information please visitETD
