Introduction
Under normal circumstances, the risks of using hydrogen peroxide to clean the ears include allergic reactions, delayed diagnosis of underlying conditions, disruption of the ear canal's microbial balance, eardrum perforation, and inner ear damage. Self-administered ear cleaning with hydrogen peroxide should be avoided in daily life. It is recommended to strictly follow medical advice and determine, under a doctor's guidance, whether hydrogen peroxide is suitable based on individual ear conditions.
Under normal circumstances, the risks of using hydrogen peroxide to clean the ears include allergic reactions, delayed diagnosis of underlying conditions, disruption of the ear canal's microecological balance, eardrum perforation, and inner ear damage.
1. Allergic reactions: Individuals with sensitive or allergy-prone constitutions may react allergically to components in hydrogen peroxide. Upon application, the immune system may recognize it as a foreign antigen, triggering an allergic response that manifests as itching, redness, swelling, or rashes on the skin around the ear.
2. Delayed diagnosis: Using hydrogen peroxide for ear cleaning may temporarily alleviate symptoms but could also mask the true severity of an underlying condition, leading patients to delay seeking proper medical care.
3. Disruption of ear canal microecological balance: Hydrogen peroxide has antibacterial properties. When used as ear drops, it may disrupt the natural microbial balance in the ear canal, reducing beneficial bacteria and allowing harmful bacteria to proliferate, potentially leading to infectious diseases.
4. Eardrum perforation: Improper administration of hydrogen peroxide into the ear—such as administering it too quickly, applying excessive force, or sudden head movements by the patient—may create strong pressure against the eardrum, potentially causing rupture or perforation.
5. Inner ear damage: Hydrogen peroxide is oxidizing in nature. If the eardrum is already perforated, the solution may enter the inner ear via the Eustachian tube and cause oxidative damage to delicate structures such as hair cells and nerves in the inner ear.
To prevent these risks, avoid self-administering hydrogen peroxide for ear cleaning. It is recommended to strictly follow medical advice and professional guidance, and determine whether hydrogen peroxide use is appropriate based on individual ear health conditions.
