Localized cyst on ventral side of auricle

Introduction Auricular pseudocyst (known as auricular serous perichondritis) is an unexplained localized cyst of the abdomen of the auricle. Because it has no epithelial layer on the wall, it is called a pseudocyst. The majority of patients are male, and the age of onset is generally 30 to 40 years old, mostly occurring in one side of the auricle. The etiology and pathogenesis of this disease are unknown. After the onset, the puncture can be repeatedly puncture under aseptic operation, and the dexamethasone is injected after the injection. In order to prevent the recurrence of the effusion, the part should be pressure-wrapped. In order to shorten the treatment time, a small window can be opened in the whole layer of the capsule wall under strict aseptic operation, and after the effusion is discharged, the partial pressure bandaging can be performed, and the healing can be cured within one week.

Cause

The etiology and pathogenesis of this disease are unknown. After the onset, the puncture can be repeatedly puncture under aseptic operation, and the dexamethasone is injected after the injection. In order to prevent the recurrence of the effusion, the part should be pressure-wrapped. In order to shorten the treatment time, a small window can be opened in the whole layer of the capsule wall under strict aseptic operation. After the effusion is drained, the partial pressure bandaging can be performed, and it can be cured within one week. In addition, magnetic therapy, ultrashort wave diathermy physical therapy, etc. can be tried. . Maintain local cleansing after illness, do not apply drugs, so as to avoid secondary infection and suppurative perichondritis, auricular deformity.

Diagnose based on

1. More common in adult males, often full of unilateral auricles.

2. Cysts occur mostly in the abdomen of the auricle, with a hemispherical bulge, clear boundaries, normal skin color, hard or fluctuating.

3. Puncture can extract light yellow or bloody water-like liquid, and relapse soon after pumping.

Differential diagnosis

Differential diagnosis of localized cysts on the ventral side of the auricle;

1. Lymph node enlargement in the ear: In people's lives, people often have a cold or other infection, neck, ear, armpit or groin can appear as a nodule of glass sphere size, local redness and tenderness, according to the hard, This is suffering from lymphadenitis. Lymph node enlargement in the ear is one of the common diseases in children. The causes are mostly Staphylococcus aureus and hemolytic streptococcus.

2, mastoid edema after the ear: mastoid edema after the ear is the clinical symptoms of acute suppurative mastoiditis. There is a continuous mucosal phase between the middle ear mastoids, and there is an inflammatory reaction in the mastoid mucosa after the middle ear purulent infection. The initial stage is catarrhal, the mastoid area may have mild tenderness, the perforation of the tympanic membrane is pus, the mastoid The inflammatory response disappears. If the drainage is not smooth, or type III pneumococcal infection, the toxicity is very strong, destroying the bone, so that the mastoid small mucosa edema, hemorrhage, necrosis, it becomes acute suppurative mastoiditis, actually the follow-up of acute otitis media It should be called acute suppurative otitis media.
