Can hydrogen peroxide be used to clean a perforated eardrum?

Hydrogen peroxide usually refers to hydrogen peroxide solution. It is acceptable to clean the ear with hydrogen peroxide solution in cases of eardrum perforation. The specific analysis is as follows:

When the eardrum is perforated, the barrier between the external auditory canal and the middle ear cavity is compromised, making it easier for bacteria and other microorganisms to enter the middle ear and cause infection. Hydrogen peroxide has strong oxidizing properties and can decompose to produce oxygen and water. The released oxygen during this process helps disrupt the living environment of bacteria and other microorganisms, thereby achieving antibacterial and disinfecting effects. Meanwhile, the foam generated during the decomposition of hydrogen peroxide can loosen and remove secretions and crusts within the external auditory canal, helping maintain ear canal cleanliness. Therefore, in cases of eardrum perforation, appropriately using hydrogen peroxide to clean the external auditory canal can help prevent infection and promote healing.

In daily life, it is important to keep the ear canal clean and dry, avoid letting contaminated water or foreign objects enter the ear canal, and reduce the risk of infection.
