TYMPANOGRAM - IS MY ENT DOCTOR'S SUGGESTION HASTY?

I have a long standing right ear hearing problem and visiting an ENT specialist for the same. Due to my request he referred to a famous hospital specialized in ENT alone in my city. They took CT scan of the temporal bone, audiometey (of course which showed the existing hearing loss) and typanometry. The CT of the temporal bone revealed chronic mastoidits with soft tissue densitites in the right middle ear. The ENT hospital doctor asked to forget about the CT scan because its a pre-existing marker and nothing to fuss about. But they advised to take a nasal spray for my nose to reduce the allergy. My old tympanograms revealed conistent Type A in my normal left ear and type B in the problem right ear which may indicate fluid or some other. Meanwhile the ENT hospital doctor advised me to take the nasal spray for a month and repeat the typanogram, which revealed type B in the problem right ear and pressure not attained in the normal left ear. Today when I visited the hospital after a month they repeated the typanogram and it revealed Type C in the problem right ear and a B in the hitherto normal left ear. I wondered and raised my doubts which the ENT hospital doctor refused to listed and advised surgery (myringtomy) in the left ear to remove the fluid. I WENT FOR THE PROBLEM IN THE RIGHT EAR AND NOW THEY ARE FOCUSSING ON THE LEFT EAR as it showed Type B just today without wait and see approach. Immediately I rang to my orignal ENT doctor who referred to this hospital. I repeated the typanogram immediately in another famous Audiology test center and it revealed (THE TIME GAP FOR THE TWO TEST IS HALF AN HOUR) Type A in the normal left ear and Type As in the problem right ear( which is an improvement from B to As). What would have happened if I go by the word of the ENT hospital specialist and do my operation in the normal left ear to remove the fluid? How the value revealed that the left ear is (always) normal in another lab? Won't the specialist correlate by physical examination with an otoscope? Why this hastiness? What shall I do now? Can I go back to the hospital and reveal the report to the specialist there? I think they will simply ask me to get out of the hospital and see some where else. Was it commercialised at the cost of patient's welfare. THE REAL PURPOSE OF VISITING A LEADING HOSPITAL FOR KNOWING THE REASONS FOR MY AFFECTED RIGHT EAR WAS NOT MET WITH INSTEAD IT TOOK ANOTHER DIMENSION. Who has to be carefull the doctor or the patient? KINDLY ENLIGHTEN MY BY YOUR SUGGESTIONS IN THIS REGARD
