Welcome in H.C.M.
I have gone through your query regarding post operative complications of tube insertion on your ear drum to equalize air pressure in middle ear to that of external environment.
Unfortunately you developed post operative infection after two days of surgery and it takes few weeks to clear up. During this period your tube is being expelled out and a big perforation developed in your ear drum leading to gross hearing loss
Now your doctor is trying to repair your drum, please Waite for healing to take place. I think your doctor has taken right decision.
