Ear keloid removal is performed under local anesthetic. You may feel some movement or light pressure while the procedure is being performed, but the area should be numb during surgery.
The surgical approach depends on the location and size of the keloid and the amount of normal tissue available. In some cases, the entire keloid can be removed. In others, removing all of the scar tissue may create unnecessary tension or distortion of the ear, and a different approach may be more appropriate.
Extralesional Excision
When there is enough surrounding tissue to close the wound appropriately, it may be possible to remove the entire keloid around its outer border. This is called an extralesional excision.
Intralesional Excision
If removing the entire keloid would leave insufficient skin for closure or create excessive tension, the firm central portion of the keloid can instead be “cored out.” This is called an intralesional excision.
The remaining keloid skin can then be used as skin flaps to close the wound.
When Might a Staged Procedure Be Needed?
Most ear keloids can be treated in a single procedure. However, very large keloids or those that significantly involve the surrounding skin may require treatment in stages.
If removing the entire keloid at once would not leave enough healthy skin for closure, an intralesional excision may be used so that some of the overlying keloid skin can be preserved and used as a flap. Once the ear has healed, any remaining keloid tissue can be reassessed and additional treatment planned if needed.
Preserving the Shape of the Ear
The amount of normal skin available matters when planning ear keloid removal. Removing too much tissue can make closure difficult or place unnecessary tension on the wound.
For that reason, the goal is not simply maximal removal of scar tissue. I also consider how the remaining tissue can be used for closure and how the procedure may affect the contour of the earlobe or ear.
Sutures and Dressing
The incisions are closed with sutures. Depending on the location and closure, removable sutures are generally removed at approximately 7 to 10 days, while dissolvable sutures may take 2 to 4 weeks to dissolve.
A dressing may be placed after surgery and wound-care instructions are provided.
