EarCheck Monitor


Can you tell me about the new EarCheck monitor and how it works?

Dr. Greene's Answer

The EarCheck machine is far more accurate than ear thermometers, but just as easy to use. It slips into the ear, you press a button, the child hears a chirping noise, and within five seconds a tremendous amount of information is given concerning what’s going on inside that ear. This device could revolutionize the treatment of ear infections.

The ear is an amazing thing. Normally sound waves reaching the eardrum cause it to vibrate. The vibrations send a signal to the brain that the brain translates into an incredible range of sounds. EarCheck works by sending sound waves into the child’s ear. It then measures them bouncing back off the eardrum, thereby assessing its mobility. If there is fluid behind the eardrum (always present in otitis media), the eardrum will not be as mobile as it normally is. This lack of mobility is one of the reasons hearing loss occurs during ear infections.

If the EarCheck monitor gives you a “Green, Level 1” light, then you know the eardrum is functioning well. There is a 96.6% chance that there is no fluid in the middle ear, and that your child does not have an ear infection. If the EarCheck monitor gives you a “Red, Level 5” light, the eardrum is not moving well, and there is up to a 92% chance that there is fluid in the middle ear. If the EarCheck monitor gives a red reading, the child’s ear should be looked into by a physician who can determine exactly what is going on. A yellow or red light may or may not represent an infection. Even if it does, it may or may not need antibiotics.

If it turns out that your child has an ear infection, you can track the progress of the infection by using the EarCheck device at home. When the light turns green you can relax and know that the ear infection is resolved and fluid has left your child’s ears. (Even if the light does turn green, don’t stop any medicines that have been prescribed without discussing this with your physician.)

My biggest concern about the EarCheck is that parents may get a yellow or red reading and then call a physician and urge the doctor to prescribe an antibiotic without an office visit. This would be extremely unwise. While keeping kids out of the doctor’s office is a good idea as much as possible, the EarCheck does not give enough information to determine if antibiotics are necessary or not. Often when the light is yellow or red the child will not have an ear infection. Even if there is an infection, it may well be one that can resolve without antibiotics. If a doctor looks into the ears and determines that this is the kind of ear infection that does not benefit from antibiotics, then you can use the EarCheck at home to monitor the progress of the ears. Later, you and your physician can use the information you get from the EarCheck device to decide if the infection is clearing on its own or if medicine should be started.

The EarCheck monitor is available from a limited number of sources. To find out where you can purchase the EarCheck, you can call them at (888) EAR-CHEK (327-2435). For ear-infection-prone children, this wonderful device will quickly pay for itself by saving on unnecessary visits to the doctor. It will also give new information to parents that will equip them to be more active in making sure their child gets the care he or she needs.

In addition, the EarCheck could be an asset to physicians because it could give more information to them about the pattern of ear infections in the children they take care of. Currently, most pediatricians have a follow-up ear re-check appointment about three weeks after the first visit. At that time the doctor can determine if the ear infection is gone or not. If it is gone, the doctor doesn’t know how long it has been gone. Now the parent can check the child’s ears on a daily basis in the comfort of their own home and determine when there is no longer fluid in the ear. This gives the doctor additional information that can be used in future treatment. All in all this should result in a tremendous increase in care.

Using the EarCheck monitor can take the worry and guesswork out of the decision to see a doctor or not. Being able to detect fluid in the ear, using a simple and painless device while in the comfort of your own home, is a tremendous advance that could make the mystery and wondering behind the screaming in the night a thing of the past.
