The part of the cheek close to the ear is mainly the parotid gland. Since the sebaceous glands in this area are more abundant and easily breed sweat, and the cleaning process is easily neglected, it can easily cause sebaceous cysts, making the patient appear as hard bags and hard lumps. In addition, mumps, lymphadenitis or parotid tumors may also cause patients to have similar symptoms: 1. Sebaceous cysts: when the patient’s cheek and ear connection area is infected due to improper cleaning, sweat contamination or epidermal breakage, resulting in blockage of the sebaceous ducts, secretions that cannot be discharged, etc., cysts may form. They usually appear as localized lumps, which may be smooth and smooth on the surface of the skin and are moderately hard. For smaller cysts that do not affect normal life can continue to be observed, when there is a tendency to increase, surgery can be taken, or laser treatment can be chosen; 2, parotitis: parotid gland is the largest salivary gland, the duct is thick and long and many branches, easy to cause infection. When the pus from inflammation gradually increases, a hard mass will appear when it accumulates for a long time. In addition, if there are symptoms such as fever, headache, loss of appetite, etc., mumps is considered more likely. It is recommended to treat with ribavirin, dexamethasone, mannitol, and Ruyi Jinhuang San under the guidance of a doctor. A few chronic obstructive mumps can also be treated with surgery when it seriously affects life. 3. Lymphadenitis: If the lymph nodes in front of the auricle are infected with bacteria or viruses, it can lead to redness and swelling in the area, which can be painful when pressed, and gradually harden when the pus accumulates to a certain level, which can take the form of hard pockets. Patients are recommended to actively treat the primary lesion under the guidance of doctors, and can use antibiotics such as cefadroxil, penicillin sodium, roxithromycin, antipyretic and analgesic drugs such as ketoprofen gel, and antiviral drugs such as ganciclovir and adenosine monophosphate for treatment, and incision and drainage can also be performed when the abscess is too large; 4. parotid tumor: if the mass is located under the parotid gland, and the surface is smooth, movable and hard, and painful when spontaneous or touching, then there is a certain tumor. If the lump is located under the parotid gland, and the surface is smooth, movable, hard and painful when touching or spontaneously, there is a certain possibility of tumor. After the diagnosis of parotid tumor, surgery is recommended as the first choice, followed by chemotherapy or radiation therapy to maximize the quality of life and life expectancy of patients.
