hi iam from Asia and working in Asia
it would be v nice if u could let us know what kinda ear problms u have got, just to help u better on this....
i had a tube in my right ear last june and renewed my medical with that and got a class one, my AME never asked anything about it...i had the tube because of difficulty in equalizing on decent...
u will definitly need to take v good care of ur ear if u have the tube...if u dont let any water in the ear it wont cause any problm...just use an ear plug when u take showers and keep the ear dry...thats all u need and vissit a doc once a month to have a chek on the tube...

gud luk
