There may be the following clinical reasons for the thickening of the earlobe: The first reason is that the patient may have an increase in weight, which leads to an increase in fat in the earlobe area, and the increase in fat will also lead to a thickening and enlargement of the earlobe. This is a slow process where the patient has no obvious discomfort, but the patient has a significant weight gain during the clinical examination. The second reason is that some patients have inflammatory irritation of the earlobe, which leads to inflammation of the local soft tissue of the earlobe. Once inflammation occurs, the earlobe will thicken, and in this case there will be local changes related to redness, swelling, heat, pain, etc. The third reason is that some patients have chronic eczema in the earlobe. The stimulation of chronic eczema leads to repeated thickening of the earlobe and changes such as itching and exudation on the surface, and chronic eczema can lead to thickening of the skin and subcutaneous tissue of the earlobe. In conclusion, it is recommended that the patient visit an ENT clinic to see what causes the thickening of the earlobe and to see if treatment is necessary.
