External application of auricle perichondritis has no effect, while auricle perichondritis is also called auricle pseudocyst, which is a kind of aseptic and serous exudation in cartilage. Its etiology is generally due to local microcirculation disorder caused by patients' unintentional repeated touch or extrusion of auricle. Generally, patients will inadvertently find that there may be localized bulges in the front upper part of the auricle, which are round or oval, from small to large, with no local pain. However, when the cyst continues to grow, the patient will have a feeling of stuffiness in the auricle. The cyst is usually located in the navicular fossa or triangular fossa behind the ear, and yellowish liquid can be extracted by local puncture. In terms of treatment, early patients can carry out local puncture, blood drawing and pressure bandaging, with good results. However, if there is no improvement after repeated puncture, local surgical incision and drainage treatment are needed. Antibiotics are also needed after the operation to avoid local infection. It can be cured in about a week. Medication and wiping have no effect.
