How to restore a bulging eardrum

If the eardrum is perforated, it means there is inflammation. Generally, the patient will not only feel the eardrum bulging outward, but also fluid flowing out. In order to avoid inflammation and bacterial infection, the patient needs to clean the purulent fluid in the ear regularly and give appropriate medication. The ear is a sealed channel, so it must be kept dry regularly.

(I) Cauterization is suitable for very small tympanic membrane 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.

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. (III) Full inversion lining method ① Incision.

② Peel off the skin of the external auditory canal.

③ Scrape off the epithelium at the edge of the perforation.

④ Loosen the fiber drum ring.

⑤ Lay out the transplanted tissue.

⑥Padding and suturing.

② Peel off the skin of the external auditory canal in the same way as the full lining method.

③ Separate the epithelial layer and fibrous layer of the remaining tympanic membrane.

④ Lay the transplanted tissue, which is sandwiched between the epithelial layer and the fibrous layer of the tympanic membrane.

⑤ Fill and suture the incision with the full inversion lining method.
