A cyst in the ear needs to be treated according to its cause, including true cysts and pseudocysts, and after a clear diagnosis, general treatment, medication, surgery and other methods should be chosen according to the doctor’s instructions. 1. True cysts: If a cyst in the ear is true, and the cyst is small and asymptomatic, you can choose to observe it regularly without treatment. If the cyst is large and there is obvious discomfort, you can choose surgery to remove the cyst. If the infection is combined, you can apply erythromycin ointment and mupirocin ointment as prescribed by the doctor to improve the symptoms. 2. Pseudocysts: cyst-like elevations formed after exudate aggregation on the inner side of the auricle are pseudocysts. If there is no infection, you can choose to puncture and compress the treatment, and if necessary, you can choose surgery. Different cysts in the ear are treated in different ways, and it is recommended that patients go to the hospital in time to improve the examination and take standardized medication and treatment according to the doctor’s instructions.
