Preventing keloids before planned surgery

If you are prone to keloids and have surgery coming up, the time to plan prevention is before the incision, not after the scar appears. Anyone who has keloided before, or has a strong family history, should tell the surgeon in advance so the operation and the aftercare can be built to lower the odds of a new keloid forming along the wound.

Surgical technique matters first. A closure under low tension, careful handling of the tissue, and, where the choice exists, an incision placed along relaxed skin lines all reduce the mechanical stress that drives scar overgrowth. For elective procedures, a keloid-prone patient and surgeon can sometimes plan the approach specifically with that risk in mind.

The aftercare is where most prevention happens. Once the wound has closed, silicone sheeting or gel and steady pressure applied over the healing scar for weeks to months are the best-supported measures for keeping a scar flat, the same tools used to stop everyday keloids from forming. Starting them early and using them consistently is what makes them work.

For patients with a serious keloid history undergoing higher-risk surgery, a dermatologist may plan adjuvant steps in advance, such as steroid injection into the healing scar or, in select cases, post-operative radiation, the same strategy used to keep excised keloids from returning. This is a conversation to have before the operation, not a rescue after a keloid has already grown.
