A small piece of the growth may be removed so it can looked at under a microscope (biopsy). This may be done to rule out skin cancer and confirm the diagnosis.
TREATMENT
Sometimes the condition clears up on its own with time, but usually treatment is needed. Treatment may involve:
Using a type of sponge or cushion to keep pressure off the helix while you sleep (ear prosthetic).
Applying a cream or ointment (topical therapy) to:
Kill bacteria.
Reduce inflammation.
Increase blood flow.
Injection therapy, which may involve:
Getting injections of steroids to reduce inflammation.
Getting cartilage injections to cushion the nodule.
Having surgery to remove the nodule. This may be done if other treatments do not help. Surgery may involve:
Freezing the area (cryosurgery).
Laser surgery.
Scraping out the core of the nodule (curettage).
Removing the nodule and some cartilage below it (wedge resection).
