OVERVIEW

What is suppurative perichondritis of the auricle?

Suppurative perichondritis of the auricle is an infection with pus formation between the cartilage and perichondrium following auricular injury, causing severe pain and potentially leading to cartilage necrosis and deformity. It requires prompt and serious treatment.

SYMPTOMS

What are the common manifestations of suppurative perichondritis of the auricle?

• Initially, there is a sensation of swelling and pain in the auricle, with redness, swelling, heat, and pain gradually worsening and spreading, leading to increasing discomfort. In severe cases, it may later cause necrosis and deformity of the auricular cartilage.

• Examination reveals redness, swelling, and significant tenderness in the auricle. When an abscess forms, fluctuation may be felt, and some cases may rupture and discharge pus.

CAUSES

What are the causes of suppurative perichondritis of the auricle?

Trauma, surgery, frostbite, burns, infection from ear acupuncture, and secondary infection of auricular hematoma. Pseudomonas aeruginosa infection is the most common, followed by Staphylococcus aureus infection.

Who is commonly affected by suppurative perichondritis of the auricle?

It occurs in individuals who undergo ear acupuncture procedures or ear surgery, as well as those with ear trauma.

DIAGNOSIS

How is suppurative perichondritis of the auricle diagnosed?

Diagnosis is generally made based on patient symptoms and physical examination:

• Symptoms include swelling and pain in the auricle, with obvious redness, swelling, heat, and pain, gradually leading to discomfort and restlessness.

• Examination reveals redness and swelling of the auricle, significant tenderness, and fluctuance if an abscess forms. Some cases may present with pus discharge due to rupture.

What tests are needed for diagnosing suppurative perichondritis of the auricle? Why are these tests performed?

• ENT specialist examination: Helps determine whether an abscess has formed.

• Complete blood count (CBC): Assists in assessing the infection status.

• Bacterial culture of secretions: Guides the selection of sensitive antibiotics to control the infection through culture and susceptibility testing.

TREATMENT

Which department should I visit for suppurative perichondritis of the auricle?

Otolaryngology (ENT).

What are the treatment options for suppurative perichondritis of the auricle?

• Systemic use of sensitive antibiotics to control infection.

• In the early stage before abscess formation, local physical therapy can be applied to reduce inflammation.

• If an abscess forms, a semicircular incision should be made along the scaphoid fossa on the inner side of the helix under anesthesia to fully expose the abscess cavity, remove pus, scrape away granulation tissue, and excise necrotic cartilage. Preserving the cartilage in the helix area can prevent future auricular deformity. During surgery, the cavity should be thoroughly rinsed with a sensitive antibiotic solution.

• After surgery, the skin is repositioned over the wound, a drainage strip is placed without suturing to prevent postoperative hematoma or fibrosis-induced contraction. The area is then bandaged with moderate pressure, and dressings are changed daily.

• If severe deformity affects appearance, reconstructive surgery may be performed.

Can suppurative perichondritis of the auricle heal on its own?

No, it does not heal on its own. The condition progresses rapidly, so early medical attention is recommended.

What are the common side effects of medications for suppurative perichondritis of the auricle?

Medications include antibiotics, which may cause gastrointestinal discomfort (such as diarrhea, stomach upset, nausea, vomiting), allergic reactions, or potential effects on liver and kidney function.

Are there any sequelae after treatment for suppurative perichondritis of the auricle?

If treatment is delayed and the lesion expands, sequelae such as auricular deformity may occur.

Is follow-up necessary for suppurative perichondritis of the auricle?

It is best to follow the doctor's instructions and return to the ENT department for a follow-up visit. The condition is considered cured once all symptoms subside.

Can suppurative perichondritis of the auricle be completely cured?

With proper treatment, a full recovery is possible.

Can suppurative perichondritis of the auricle recur after treatment? What should be done if it recurs?

Recurrence is possible. If it recurs, seek medical treatment promptly.

DIET & LIFESTYLE

What should patients with suppurative perichondritis of the auricle pay attention to in their diet?

There are no special dietary considerations, a normal diet is sufficient.

PREVENTION

Can Suppurative Perichondritis of the Auricle Be Prevented? How to Prevent It?

Yes, it can be prevented. During auricular acupuncture therapy or ear surgery, strict disinfection should be performed to avoid cartilage damage. Promptly treat auricular trauma, thoroughly debride wounds, and strictly prevent infection.
