Perichondritis of the ear

Perichondritis is an inflammation of the perichondrium, a layer of connective tissue that surrounds the cartilage of the ear. This condition can lead to severe complications if not treated promptly, as it may result in the destruction of the cartilage and subsequent deformity of the ear.

Causes

Perichondritis is often caused by an infection, which can occur following trauma to the ear, such as a piercing, surgery, or injury. The most common bacteria responsible for this infection is Pseudomonas aeruginosa, although other bacteria can also be involved.

Symptoms

The symptoms of perichondritis include:

• Redness and swelling of the ear
• Pain and tenderness
• Warmth over the affected area
• Possible fever

Diagnosis

Diagnosis of perichondritis is primarily clinical, based on the appearance of the ear and the patient's history. A culture of any discharge may be taken to identify the causative organism.

Treatment

Treatment of perichondritis typically involves:

• Antibiotics: Oral or intravenous antibiotics are used to treat the infection. Pseudomonas infections often require specific antibiotics such as ciprofloxacin.
• Incision and drainage: In cases where an abscess has formed, surgical intervention may be necessary to drain the pus.
• Pain management: Analgesics may be prescribed to manage pain.

Complications

If left untreated, perichondritis can lead to:

• Chondritis, an infection of the cartilage itself
• Cauliflower ear, a deformity caused by cartilage destruction
• Permanent ear deformity

Prevention

Preventive measures include:

• Proper care and hygiene following ear piercings or surgeries
• Avoiding trauma to the ear
• Prompt treatment of any ear infections
