Skin necrosis after liposuction

Full-thickness dermal necrosis can result from excessive superficial liposuction that directly injures the vascular supply of the overlying skin. Other causes of full-thickness dermal necrosis after liposuction include flap necrosis, infection, thrombosis, and vasculitis.

Can liposuction cause skin necrosis?

Skin necrosis can occur with liposuction if the surgeon uses the liposuction cannula to intentionally injure the skin (some surgeons erroneously believe that injuring the skin will encourage contraction of the skin).

What causes dermal necrosis after liposuction?

Full-thickness dermal necrosis can result from excessive superficial liposuction that directly injures the vascular supply of the overlying skin. Other causes of full-thickness dermal necrosis after liposuction include flap necrosis, infection, thrombosis, and vasculitis.

Is dermal injury necessary for liposuction?

A deliberate iatrogenic injury to the dermis with a liposuction cannula is reminiscent of “blood letting” as treatment for inflammation; there is no scientific support that either is beneficial. Dermal injury is not necessary for skin contracting after liposuction.

Why does skin contract after liposuction?

Skin naturally contracts after liposuction because 1) skin naturally contains elastic fibers, 2) skin is relieved of the gravitational effect of subcutaneous fat, and 3) liposuction naturally results in contraction of the collagen in subcutaneous fat.

Can ultrasonic liposuction cause skin necrosis?

It is not unusual for ultrasonic assisted liposuction (UAL) to cause skin necrosis as a result of ultrasonic energy burning the skin or burning blood vessels that supply the skin. Finally, a rare type of severe bacterial infection can cause necrotizing fasciitis of the skin.

What causes dermal necrosis after liposuction?

Full-thickness dermal necrosis can result from excessive superficial liposuction that directly injures the vascular supply of the overlying skin. Other causes of full-thickness dermal necrosis after liposuction include flap necrosis, infection, thrombosis, and vasculitis.

Can liposuction cause bleeding?

Bleeding into a closed space under the skin (hematoma), or the leakage of serum into closed space under the skin (seroma) can occur after liposuction. There is an increased risk of these types of complications associated with obesity, excessive liposuction with a large cannula, and with ultrasonic assisted liposuction (UAL).

Is dermal injury necessary for liposuction?

A deliberate iatrogenic injury to the dermis with a liposuction cannula is reminiscent of “blood letting” as treatment for inflammation; there is no scientific support that either is beneficial. Dermal injury is not necessary for skin contracting after liposuction.
