And one more question for ent, sir can a person travel in unpressurized air cabin with eardrum perforation? thank you sir..?

With perforated eardrums, pressure cannot be built in the middle ears so it does not matter pressurized or unpressurized air cabin. The only problem is low oxygen in high altitude with unpressurized cabin.

Hello. Might be a good idea to use some afrin and purchase “Ear Planes” if you have had trouble flying and equalizing ear pressure in the past. I’m assuming you don’t have bilateral ear drum perforations. Also, tympanic membrane (TM) perforations usually heal quickly if the edges are well aligned. The healed TM heals without the middle fibrous later so pain can be worse with altitude changes.
