Introduction
White pimple-like bumps in the ear may result from an inflammatory response due to bacterial infection in the middle ear, causing a large amount of pus to accumulate locally within the middle ear. Alternatively, it could be a sebaceous cyst formed when the sebaceous gland ducts in the external auditory canal become blocked, presenting as a pus-filled bump. It might also occur when the skin of the bony portion of the external auditory canal is infected by bacteria, leading to white blood cell accumulation at the site of injury, resulting in a raised white pustule.

White pimple-like abscesses in the ear may be caused by conditions such as otitis media, external auditory canal furuncles, or sebaceous cysts. Specific analyses are as follows:

1. Otitis Media

When the middle ear becomes infected by pathogens and develops an inflammatory response, a large amount of pus is secreted locally and accumulates within the middle ear, forming small abscesses. It is recommended to take antibiotics under medical supervision, such as cefaclor capsules, cefprozil tablets, or azithromycin dispersible tablets, to control inflammation and relieve symptoms.

2. External Auditory Canal Furuncle

When the skin of the bony portion of the external auditory canal is infected by pathogens such as Staphylococcus aureus, white blood cells accumulate at the site of injury, manifesting as raised white abscesses. Patients should visit a hospital where trained physicians can apply local heat therapy or infrared radiation to promote maturation of the furuncle and drainage of pus, thereby improving symptoms.

3. Sebaceous Cyst

The skin of the external auditory canal contains abundant sebaceous glands and hair follicles. When the sebaceous gland duct becomes blocked, it can easily lead to the formation of a sebaceous cyst, which may appear as an abscess. If there are no obvious discomfort symptoms, specific treatment may not be necessary. However, if the cyst becomes infected, prompt medical attention is required, and surgical drainage of the pus should be performed to promote healing.

In addition, similar symptoms could also result from cholesteatoma, ceruminous adenoma, osteoma, or other causes. Accurate diagnosis requires appropriate examinations at a hospital, followed by suitable treatment measures.
