Introduction
Introduction Suppurative auricular perichondritis examination showed redness of the auricle. Auricular perichondritis can be divided into two types: serous and suppurative. The lesion is serum exudation (slurry) or pus formation (suppurative) between the cartilage and the perichondrium. The serous person often only has a limited auricle swelling, a sense of elasticity, no redness, no obvious pain, and some have swelling, burning and itching. Some puncture can extract a pale yellow serous liquid, and the culture has no bacterial growth. Suppurative auricle pain, check the auricle redness, obvious tenderness, fluctuations, and some ulceration.
Cause
Cause
Auricular serous perichondritis, also known as pseudocyst of auricle, is a sterile inflammatory response of the perichondrium. The cause is unknown and may be associated with repeated mechanical trauma such as compression or touch. Suppurative perichondritis is an acute suppurative inflammation of the auricular perichondrium and cartilage, often caused by trauma, surgery, frostbite, burns, and auricular hematoma secondary infection. It should be taken seriously because it can cause cartilage necrosis and cause auricular deformity.
