Perforated Ear Drum

Should we use cotton-tipped swab to remove ear wax?

People mentioned that eardrum could be ruptured easily, especially when the eardrum is poked. Others said that the change of air pressure during flight or sneezing too hard could cause perforated eardrum. Can our eardrum be ruptured that easy?

(1) Where is eardrum located? Can the things mentioned really rupture our eardrums? Any other common causes?

(2) What are the symptoms when eardrum is perforated? Would it affect our hearing?

(3) How is a Ruptured Eardrum Treated?

(4) “It’s better to use cotton-tipped swab instead of curette to remove ear wax.” Is that a correct statement? How should we keep our ears clean?
