The first thing to do is to improve the relevant examination, according to the degree of damage, location, etc., to take standardized treatment. After the eardrum is punctured by a cotton swab, it is necessary to actively consult a doctor for a systematic examination to clarify whether there is any foreign body in the ear canal and middle ear cavity, to understand the size and location of the eardrum damage, and to find out whether there is any dislocation or fracture of the auditory ossicle chain, and then recommend whether it is necessary to take timely and reasonable therapeutic measures after assessment by a specialized doctor. If the perforation is relatively small and there is no dislocation or rupture of the auditory ossicular chain in the broken eardrum, it usually heals on its own in about 3 to 4 weeks as long as there is no secondary infection. If the eardrum is punctured by a cotton swab and the perforation is large, it may not be able to be repaired on its own, which will have a great impact on hearing, and prompt hospitalization is needed to take eardrum repair surgery. After the eardrum is punctured by the cotton swab, it is best to go to the ENT department of the hospital in time, and be examined by the doctor to make a clear diagnosis and then targeted treatment or therapy.
