The itchy inside of headphones may have the following clinical causes. 1. Long-term wearing of headphones leads to restricted exclusion of cerumen from the ear canal, and the accumulation of cerumen may easily induce changes such as otitis externa in the external ear canal, so ear itch occurs. 2. Some patients wear headphones for a long time, and the headphones often rub against the ear canal, leading to local skin erosion and ulceration of the ear canal, which induces otitis externa and ear itch. 3. In some cases, the headphones can cause excessive sweating inside the ear, and excessive sweating may easily induce changes such as eczema in the ear canal. 4. When wearing headphones for a long time, the surface of the headphones can easily induce fungal infections, which can lead to fungal otitis externa and ear itch. All in all, if a patient wears headphones and has itchy ears inside, it is recommended that the patient first try not to wear headphones. If you have the conditions, you should go to the hospital to check to see what kind of disease it is, and then carry out the symptomatic treatment treatment.
