The time to self-healing of tympanic membrane perforation is related to its etiology and severity. In the case of traumatic tympanic membrane perforation, the perforation is small and there is no secondary infection, and usually heals spontaneously in 2-3 weeks. If the perforation is large, the chances of natural healing are low, at about 20%, and patients who have not healed spontaneously in 3 months will require tympanic membrane repair surgery. In the case of acute suppurative otitis media causing perforation of the eardrum, the perforation is small and can heal spontaneously in about 1 week if the inflammation is completely controlled and there are no recurrent attacks. In the case of chronic suppurative otitis media and recurrent acute suppurative otitis media, the tympanic membrane perforation is usually difficult to heal on its own, and those who have not healed after 3 months of inflammation control require tympanoplasty. Patients with tympanic membrane perforation should seek prompt medical attention from the ENT department to remove foreign bodies, clots, and pus from the external ear canal, keep the external ear canal clean and dry during treatment, avoid catching a cold, and avoid forceful nose blowing.
