auricular pseudocyst
Introduction
Introduction to auricular pseudocyst Pseudodocystofauricle (pseudocystofauricle), also known as auricular serous perichondritis, is a sterile inflammatory response of the perichondrium. The cause is unknown and may be related to 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. The main manifestations of serousness are often only the auricle limitation swelling, elastic, non-red, no obvious pain, puncture can extract pale yellow serous liquid, culture without bacterial growth. basic knowledge Sickness ratio: 0.05% Susceptible people: no special people Mode of infection: non-infectious Complications: suppurative auricular perichondritis
Cause
Auricular pseudocyst
Not yet clear, may be related to trauma. The auricle may be affected by certain mechanical stimuli such as hard pillow compression, unintentional touch, etc., causing local circulatory disturbances.
Prevention
Auricular pseudocyst prevention
1. Don't sleep too hard on pillows.
2. Do not touch the auricle often or unintentionally.
3. After the illness, it is necessary to avoid various mechanical stimuli on the auricle.
Complication
Auricular pseudocyst complications Complications purulent auricular perichondritis
Suppurative perichondritis, auricular deformity.
Symptom
Auricular pseudocyst symptoms Common symptoms Auricular flank cystic ear itching
Most of the accidents found a limited bulge in front of the auricle, which gradually increased from small to small, and may have a swollen, burning or itching sensation, often without pain. The bulge is more than the sulcus, the triangular nest, or the mouth of the ear, but does not invade the back of the ear. The swelling range is clear, the skin color is normal, there is no toothache but a sense of elasticity, and the larger one can have a sense of fluctuation in the dark room. In the middle transmission, the transmittance is good, and it can be distinguished from the hematoma. When puncture and suction, it can be extracted but the yellow clear liquid and the culture have no bacterial growth, but soon re-exudation.
Examine
Examination of auricular pseudocyst
The auricle skin is swollen and tender, tender, and the skin temperature rises. The purulent can be puncture and pus examination.
Diagnosis
Diagnosis and differentiation of auricular pseudocyst
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
Should pay attention to the identification of the ear ulcers (suppurative auricular perichondritis). The localized ear ulcers are red, swollen, hot, painful, and can be worn out. There is pus exudate, and the cartilage of the ear shell gradually decays and even is deficient.
