Our expert says:
The grommet itself does not cause infection, as it only creates an artificial opening in the middle ear cleft. The function of the grommet is to allow air onto the middle ear, in order to ventilate the ear. Unfortunately this does not always protect against further infection, as any bacteria /virus may still find its way into the ear, usually via the nasal cavity. It is unlikely that the infection in the ear is causing the rest, as the pattern of spread is usually the other way around, ie. from the throat to the ear.
He requires an ENT examination to establish the role of the tonsils as a possible cause, as well as a propper cleaning of the ear in order for the drops to work effectively.
The reasons why the ear is not getting better could be as follows:
1. Incorrect antibiotics, due to resistance.
2. Inproper cleaning of the ear before the drops are inserted.
3. Treatment of the discharging ear with systemic antibiotics only.
The ear does not have good bacteria, unlike the rest of the digestive tract, it should in fact have no bacteria at all.
I suggest your ENT does a swab of the ear to see which organism is causing the problem, and to change the drops if this is needed. It is also important to keep the ear dry to assist with healing. The reason why the drops are not effective in this case may be due to resistance.
Unfortunately regular infections is very common in children attending daycare, and can not be avoided.
