Usually, the eardrum repair at a major hospital requires hospitalization and an incision in the ear; not to mention the pain, the cost of $10,000, and the scar left in the ear – this method is often unacceptable. In many hospitals, there are incision-free and low-cost eardrum repair methods that are a blessing to patients: 1. Cautery + growth promotion method: A special potion is applied to the edge of the eardrum perforation + growth promotion drops to make the eardrum heal automatically, which is suitable for small perforations, but a follow-up visit is required every 2 weeks for about $100 or so until it heals. 2.Ear endoscopic eardrum repair, under local anesthesia and endoscopic guidance, the eardrum can be repaired without cutting the ear, suitable for repairing larger perforations, costing about 1000 yuan, usually two weeks after surgery when the review has grown well, success rate > 80%. The indications for tympanic membrane repair are as follows: 1. Acute perforation of the eardrum (such as ear trauma) that has not healed on its own for more than one month. 2.After perforation of the eardrum due to chronic otitis media or other reasons, the eardrum has been dry water (no pus flow) for more than 2 months, the perforation is of central type, there is no epithelial and granulomatous vertebral accumulation in the tympanic chamber, and the eustachian tube functions well. 3, hearing test is within moderate conductive deafness, hearing can be close to normal after tympanic membrane repair. If the hearing test is mixed deafness or neurological deafness, the degree to which hearing can be restored after tympanic membrane repair should be analyzed on a case-by-case basis, but the repair can at least prevent recurrent otitis media. It should also be noted that not all cases are suitable for the above two methods. In some cases, incisional surgery is required to remove the lesion and repair the eardrum.
