How long can hearing be restored after eardrum repair surgery?

Analysis of illness: Hello, after tympanoplasty, there are hemostatic fillers such as gelatin sponge in the tympanic cavity, and there is still congestion and swelling in the tympanic membrane. The tympanic membrane itself has not been repaired, so the hearing will not be improved significantly in a short time after operation. Suggestion: Hearing should be restored 2 months after operation. If your eardrum is perforated for a long time and your cochlear nerve is damaged, your hearing may not be improved significantly after tympanoplasty. It is recommended to go to the hospital to check your hearing.
