Earwax Blocking an Pressure Equalizing Tube

The ear tube may get blocked with a little bit of earwax or dried blood, making it stop working. When this happens, it is the same as not having a tube at all, and ear fluid or an ear infection can happen again.

Sometimes, it is possible to clean out the tube with drops, but it also may be necessary for the ENT doctor to open the tube up using special instruments.
