What Causes Rash Behind Ear?

Rash Behind Ear

Hi I'm dr. David Hill and today we're going to be talking about how to drain fluid or liquid from behind the eardrum first of all we kind of have to know what's going on inside the ear and for

 that I have this model now there's the part of the ear you can see it's the external auditory

canal and this is not usually where fluid is collected in the case of an ear infection the external

 auditory canal ends right here at the tympanic membrane or eardrum that seals off what's
called the middle ear where the little bones are that carries sound to the inner ear or cochlea

this space is sealed off inside the skull but it does communicate via the eustachian tube which

is a real thin little tube that ends in the nose the eustachian tube is responsible for carrying

fluid and air out of the ear or to bring air in if that's what's needed to equalize pressure now
when a child gets a cold or allergies or a sinusitis the tube may close off and allow fluid to

collect behind the eardrum now if that fluid isn't infected it's usually not really a big deal when

 the allergies are treated to the cold goes away it tends to drain out on its own chronic fluid

collections may lead to some hearing loss and when that happens we'll usually try allergy

 treatments like nasal steroids a very short term use of decongestants or decongestant spray or
 antihistamines to try and clear that up the fact is however that studies have not shown most

 of those methods make a big difference if anything helps it's probably the nasal steroids

however studies of antihistamines and decongestants have been very disappointing in terms of

 getting this fluid out if the fluid is causing a really chronic long-term problem with hearing

loss some ear nose and throat surgeons will insert a tube called a pressure equalizing tube or

 Tempah ostomy tube in the eardrum itself to allow fluid to drain out into the ear canal

however that's usually after other modalities of treatment have failed the second time the tube

needs to be inserted he or she may also choose to take out the adenoids which may be

 blocking drainage through the eustachian to those two glands that occurs sort of in the back

of the airway between the mouth and the nose otherwise no that fluid that collects in here is

 almost always going to fix itself it may take two or three weeks to go away but it almost

always does go away in healthy children so talking about getting fluid out of the middle ear I'm dr. David Hill.
