This is extremely interesting to me!! I was told that I had abnormally small ear canals due the the Klippel Feil; but due to a recent ( I think but now am wondering) brain tumor and radiation, I have a great deal of ear wax coming especially from my right ear ( this may be because it is the side I lay on most. It seemed to have worsened after radiation. Where are you getting the tubing and how was it diagnosed?
