There are risks associated with eardrum repair surgery, and there are risks associated with any surgical operation, but the risks associated with eardrum repair surgery are not significant. A perforated eardrum is usually the result of chronic otitis media or trauma that causes the eardrum to rupture and perforate. It requires hospitalization for surgical repair under general anesthesia. The most commonly used surgical repair method for eardrum perforation used to be microscopic repair. In recent years, endoscopy has been well developed, and endoscopic tympanic membrane repair is less invasive and has a greater chance of successful surgical repair. The risks of eardrum repair surgery are mainly from the following aspects: 1. The risk of anesthesia. Any anesthetic can cause anesthesia accidents; 2. Surgical damage to the tissues surrounding the ear canal, such as damage to the facial nerve or cochlea, resulting in hearing damage or facial paralysis and other surgical complications; and 3. The survival of the tympanic membrane graft. If the tympanic membrane graft is not viable, there is a risk of surgical failure. Overall, the success rate of endoscopic eardrum repair is very high and the risks of surgery are very small, so there is no need to be overly concerned.
