1. Surgical methods for repairing tympanic perforation

(I) Cauterization

Suitable for small eardrum perforations

1. Apply a cotton pad soaked in 2% tetracaine solution to the remaining surface of the tympanic membrane for 15-20 minutes.

2. Use a small cotton swab dipped in 0.1% thimerosal tincture or 70% ethanol to disinfect the external auditory canal and the remaining tympanic membrane. Be sure not to allow the disinfectant to overflow into the tympanic cavity.

3. Use a fine probe to make a small cotton swab, dip it in 50% trichloroacetic acid solution, and carefully apply it to the edge of the perforation to create a 0.5-1.0mm white burning circle at the edge of the perforation. The purpose is to remove the epithelium and scar at the edge of the perforation and promote the regeneration of the eardrum.

After cauterization, apply a thin cotton pad containing 5% urea solution to promote the growth of the perforated tympanic membrane. After the operation, 5% urea solution was dripped 3 times a day. The cotton pad was removed after 1 week. If the perforation failed to close, it could be cauterized again until it closed. The cauterization method often needs to be repeated several times, and you should be patient and persist.

(II) Scrape and stick method

For smaller eardrum perforations

1. Apply a 2% tetracaine wet cotton pad to the remaining tympanic membrane for 15-20 minutes.

2. Disinfect the external auditory canal and the surface of the tympanic membrane with a cotton swab soaked in 0.1% thimerosal tincture or 70% ethanol.

3. Use a thin needle to scrape off the epithelium at the edge of the perforation and the epithelium 1-2mm away from the edge of the perforation. It can reach the fibrous layer of the tympanic membrane but cannot penetrate it. After the operation, a thin cotton pad soaked in 5% urea solution can be applied. Thereafter, 5% urea solution should be dripped three times a day to promote the growth of the tympanic membrane.

Remove the cotton pad after 1 week. If the perforation fails to close, repeat the above operation until the eardrum heals.

Postoperative care

1. Remove the ear sutures after 1 week.

2. Remove the ear bandage and gauze at the external auditory canal opening after 2 weeks.

3. Use a drier ethanol cotton ball to fill the ear canal opening every day, and gradually clean out the remaining sponge after 3-4 weeks. If the operation is successful, the new eardrum will be basically formed after 3-4 weeks.

4. Antibiotics should be used appropriately for 1-2 weeks after surgery
