My wife saw a patient the other day who told her that they had to have a special mask to dive because they had tubes in their ears. They said that the Ear Nose and Throat specialist told them that without (I'm guessing a full face mask that covered the ears somehow) they would drown. I could think of no possible physiological reason for it and my wife (stating she was no ear nose and throat specialist) couldn't either. I decided to post it to see if anyone else had dove with tubes and If there were any ENT specialists that were divers and could shed some more light. We both think the patient was fibbing or not really a diver.
