To determine the healing of the eardrum clinically, the following are the main aspects. 1. the patient’s symptoms, he will feel an improvement in hearing, a reduction in tinnitus, a relief of the congestion in the ear, no obvious manifestations of pus or water flowing from the ear canal, and no obvious symptoms of ear pain. 2. physical examination, mainly through electronic tympanogram, can see that the perforated area of the eardrum is beginning to shrink, showing a state of healing after perforation. A comparison with the picture of the freshly perforated tympanic membrane reveals a significant difference, as the tympanic membrane is not obviously congested at the edges, the local blood crust begins to fall off, and there is no obvious fluid accumulation or exudation in the ear canal or tympanic chamber.3. Pure tone hearing threshold examination shows a significant improvement in conductive deafness and hearing improvement, and sound conduction resistance examination shows changes such as A-curve. Traumatic tympanic membrane perforation can grow well in about two months. For patients with chronic suppurative otitis media, the tympanic membrane may also grow well in about two months for dry ears, and if it does not heal for a long time, tympanic membrane repair surgery can be done, etc.
