Scar formation is a process consequent to the healing of soft
tissues after a trauma. However, abnormal or disturbed collagen production can
cause anomalies of the cutaneous surface and textural irregularities. A
cosmetically acceptable scar is often at the level with the surrounding skin, a
good color match, soft, and narrow. Favorable lines of closure are usually
within or parallel to relaxed skin tension lines: lines due to dynamic action of
the underlying musculature.1

The scar abnormality will guide the choice of treatment technique. The surgical
strategy selected should be based on a correct evaluation of the scar’s
characteristics. In addition, while any scar with a suboptimal appearance can be
revised, greatest patient satisfaction is achieved with realistic expectations.2

In the presence of a depressed scar in deep tissue, we began to use a technique
which I believe is interesting to present. In fact, there are cicatricial
aftereffects that, though presenting a satisfactory aspect of the scar due to
the presence of an adhesion of the skin to the underlying plane, disfigure
somewhat in a disagreeable manner and therefore reconstructive plastic surgery
should be performed (Fig.​(Fig.11). Thus, in these cases especially when there
is not a lack of tissue secondary to trauma as for example the suffering of
sub-cutaneous adipose tissue, it would be sufficient to eliminate the single
adhesion without reopening the entire scar again.

Therefore, with this objective in mind, in the presence of adherent
scars, after having infiltrated the whole area with a solution of
Lidocaine 0.5% and Epinephrine 1:200,000 very close to one of the two
edges of the scar, a small incision is performed so that an undermining
scissor can enter inside (Fig.22).

The entire cicatricial area is undermined on a subcutaneous plane which,
by separating the deep scar from the superficial one, completely frees
it from the present adhesions so that the existing depression is totally
eliminated (Fig.33).

is completely undermined.
At the end of this manoeuvre, in order to avoid the recreation of
relapses, stitches formed in a U-shape are made in Nylon or Monocril
2-3/0 are made with a large needle and are placed close together so that
a wide aversion is achieved at the margins of the scar and a deep wound
closure is obtained by adhering to the undermined tissue (Fig.​(Fig.44).
These stitches will then be removed about 2 weeks later. Afterwards, the
patient should start to carry out massages on the entire treated area
using moisturizing cream to aid the mobility of the recuperated tissue.

Subcision incision is a very effective technique for correcting atrophic scars.
Essentially, the physician inserts a needle and sweeps it back and forth
repeatedly to free the skin from the underlying scar tissue.

Normally, the dissection plane of subcision is rather superficial: it is a
subdermal dissection performed successfully in the treatment of acne scars. In
this novel technique, we perform a deeper dissection plane and it is designed in
order to remove adhesions that attach the skin to the floor below. Infact, the
use of the stitches in depth is performed in order to prevent that the adhesion
can recreate again: this relapse could promote the formation of a layer of
reactive collagen in the region below the treated area.

We therefore believe that this technique can be utilized as a simple and safe
technique that brings great improvement to the treatment of depressed scars.
