Scar hypertrophy is caused by an overproduction of collagen during pathological (non-normal) wound healing. Scar tissue usually becomes thicker than the surrounding healthy skin during the first months, this normally reduces over time. Increased scar thickness is often called hypertrophy. Burn scars frequently remain hypertrophic to some extent, but scar atrophy (the scar being lower than the surrounding skin) also can happen in some scar.
Assessment of scar thickness is usually based on the amount of scar visible above the surrounding non-affected area. This doesn’t reflect the amount of scarring under the surface; high high-frequency ultrasound can be used to assess the whole thickness of the scar above and below what is visible.
