suppurative auricular perichonditis
Introduction
Introduction to suppurative auricular perichondritis Suppurative auricular perichondritis is a suppurative inflammation of the auricular perichondrium, mostly caused by auricular injury, such as trauma, surgical injury, auricular acupuncture or auricular puncture. The pathogenic bacteria are mostly Pseudomonas aeruginosa and Staphylococcus aureus. When the abscess is formed, the surface is pale yellow and has a fluctuating feeling. If improperly handled, the auricle is curled up to form a "cauliflower ear"-like deformity. Ear examinations mainly include otoscopy, eustachian tube function tests, hearing tests, vestibular function tests, fistula tests, and other tests. Generally, the size, position, presence or absence of deformity and bilateral symmetry of the auricle are observed first, and the auricle and mastoid and the lymph nodes around the ear are swollen, tender and tender. basic knowledge Sickness ratio: 0.05% Susceptible people: no specific population Mode of infection: non-infectious Complications: osteonecrosis
Cause
Causes of suppurative auricular perichondritis
Pathogenic bacteria infection (55%):
Pseudomonas aeruginosa is the most common pathogen caused by surgical injury of ear trauma or adjacent tissue infection. Followed by Staphylococcus aureus, after infection with purulent, pus accumulates between the perichondrium and cartilage, cartilage gradually necrosis due to blood supply disorders, will eventually affect the appearance and auricle physiological function.
Prevention
Suppurative auricular perichondritis prevention 1. Adjust daily life and workload, and regularly carry out activities and exercise to avoid fatigue. 2. Maintain emotional stability and avoid emotional excitement and tension. 3. Keep the stool smooth, avoid using stools, eat more fruits and high-fiber foods. 4. Avoid cold irritation and keep warm.
Complication
Suppurative auricular perichondritis complications Complications osteonecrosis
If the infection can not be controlled, cartilage necrosis, auricle shrinkage deformation (cauliflower ear).
Symptom
Suppurative auricular perichondritis symptoms common symptoms auricular redness auricular pain bloody ear secretion periosteal auricle enlargement auricular ear canal tear ear discharge auricle ventral side local cyst
1. The auricle is red, swollen, hot, painful with elevated body temperature, and general malaise.
2. The surface of the abscess is pale yellow and has a sense of fluctuation.
3. After the abscess collapses, the fistula and cartilage are formed, and the auricle deformity (cauliflower ear) is formed after melting.
Examine
Examination of suppurative auricular perichondritis
According to clinical manifestations and signs.
Ear examinations mainly include otoscopy, eustachian tube function tests, hearing tests, vestibular function tests, fistula tests, and other tests. Generally, the size, position, presence or absence of deformity and bilateral symmetry of the auricle are observed first, and the auricle and mastoid and the lymph nodes around the ear are swollen, tender and tender.
1. The examinee sits sideways, and the examiner concentrates the forehead light on the external auditory canal of the examinee, and pulls the auricle back to the upper side with one hand. If the child is a child, it should be pulled backwards to make the ear canal straight.
2. Select the appropriate size of the otoscope and rotate it into the external auditory canal.
3. The otoscope should not be placed too deep, so that it can move up and down, and observe the whole part of the ear canal and the tympanic membrane.
Diagnosis
Diagnosis and differentiation of suppurative auricular perichondritis
Modern medicine
1. Early ear has a burning sensation, local swelling and pain. The disease progresses rapidly, with more overall body temperature increase.
2. The ear profile is red, swollen, thick and tender. The abscess was palpated before the formation of parenchyma. When the abscess is formed, the auricle is dark red, confined or fully bulged, with a sense of undulation and severe pain. After the abscess ruptures, the pain is relieved and a fistula can be formed.
3, late cartilage necrosis, scar contracture, resulting in auricle wrinkle deformation is "cauliflower ear" shape.
Traditional Chinese medicine
Auricular suppurative perichondritis belongs to the category of "broken ear sores" in traditional Chinese medicine. The disease is mostly caused by local damage, and the liver and gallbladder are blazed by fire, heat and evil, and the heat is burned and the cartilage is ablated.
1, dialectical basis: often have a history of ear injury. Local redness and swelling, severe pain, and even ulceration and erosion, resulting in shedding, defect deformity. Its lesions are deep and the cartilage of the ear shell.
2, clinical syndrome: red and red swelling of the ear shell, burning hot pain, pus spilling, ear shell cartilage gradually rot such as eating, and even deformed deformity. The whole body may have fever, dry mouth and bitterness, short yellow urine, constipation, red tongue yellow, pulse number and other symptoms.
