Generally speaking, a perforated eardrum that does not exceed 30% of the tympanic membrane (approximately 30mm²) is more likely to heal on its own. A perforated eardrum is mainly caused by sudden violence or inflammatory diseases. Patients with a perforated eardrum will experience ear pain and hearing loss, as well as tinnitus and a feeling of tightness in the ear, while a few patients with a small perforation may only experience discomfort in the ear. Whether a perforated eardrum can heal on its own is related to the size of the perforation. If a perforated eardrum is caused by trauma and the perforation does not reach the edge of the eardrum, and the size of the perforation is not larger than 30% of the total area of the eardrum (about 30mm²), it is still possible that the perforation can heal on its own and return to normal. However, the larger the perforation, the longer the healing time, but generally 2 weeks to 1 month to recover, if not healed after 3 months or need surgery to repair the damage.
