Punch biopsy to optimise the healing of liposuction incisional wounds

Dear Editor, According to the data published by the American Society of Plastic Surgeons, more than 200 000 patients underwent liposuction in 2012 in the USA (1). Preliminary steps of this diffuse procedure include injection of a balanced salt solution and making of small skin incisions, generally performed by a number 11 surgical blade (2). Despite the small dimension of the incisions, there are some factors that may interfere with an optimal wound healing. In fact, the repeated and fast passage of a circular cannula on the edges of a linear incision causes thermal and physical trauma, which can cause necrosis, hypertrophic or, most frequently, hyperpigmented scars, both the incisions are sutured or healed by secondary intention (3–5). To avoid this, we routinely make liposuction or fat grafting harvesting incisions by a punch skin biopsy, choosing its diameter by thinking to the size of the largest cannula that we expect to use (Figure 1).
