Body implants are recent additions to our ability to
contour and refine the body. Silicone implants, used
to enhance the pectorals, buttock, calf and custom
sternal, and lateral thigh, are gaining popularity
The Chest
Augmentation of the male chest is usually performed
via a 5- to 6-cm transverse axillary incision, and
subpectoral space is filled with a preformed
silicone implant. Pectoralis implant models are
available for the normal to wide chest, and the
long, slim thorax. When all, or a portion of the
pectoralis is absent an implant fashioned from
moulage will likely provide the greatest symmetry.
Similar to submuscular augmentation of the female
breast, dissociative anesthesia aided by local
anesthesia (bupivicaine) may be used for chest
enlargements. However, greater muscle relaxation can
be obtained with general (paralytic) anesthesia.
The pectoral fascia at the muscle border is separated
longitudinally. Then, all muscle attachments to the
ribs must be lifted to the sternum and the
pectoralis serratus border elevated. If a pectoralis
implant suitable for a long, slim thorax is used, a
partial “S” cut may facilitate insertion. A
three-layered closure, pectoralis fascia,
subcutaneous tissue, and subcuticular polypropylene
suture is carried out. Post surgical wraps or a vest
garment can be used for 7 to 10 days. Exercise can
resume in 3 weeks and weight lifting in 6 weeks.

The Buttocks
In contrast to what is desirable in Latin America,
the quest for buttock enlargement in the United
States is small, but growing. Early attempts to
satisfy these requests with deep subcutaneous
implants usually met with encapsulation and
unnatural configuration. Fat autografts, when
properly dispersed, provide a degree of improvement.
This is especially true when combined with hip and
trochanteric liposuction. Decreasing the prominence
of these surrounding areas increases the visual
perception of buttock projection.
In 1984, Jose Robles, MD, of Argentina introduced
the concept of submuscular gluteoplasty. A round
silicone implant was placed between the gluteus
major and gluteus medius muscles. This could produce
a 2 ½ to 3cm increase in buttock projection. In the
last 9 years, I have performed subgluteal
augmentations and have developed a more anatomical
implant, which improves the outcome, but proper
orientation requires more care. The basic object is
to raise the maximum point of projection. Ancillary
procedures may be needed for the markedly ptotic
buttock.
This operation is not undertaken lightly. The patient
is advised that there is often significant
postoperative pain (controlled by Percocet) while
the heavy gluteus major adjusts to the stretch of
the implant. There may also be sciatic radiation
pain, especially if any serum or blood collects,
increasing the pressure. This generally resolves in
2 to 3 weeks. If there is any excess iliac and/or
trochanteric fat, the patient is always offered
liposuction reduction with fat injection to the
buttock as a first option. If both surrounding
fullness and gluteal flattening are present, implant
augmentation may be done at the same time as
liposuction and fat injection. However, for those
who are lean and flat, there is no alternative to
submuscular gluteoplasty to provide a natural
projection and contour.
The operation is performed though a 7-cm incision in
the natural crease, starting at the tip of the
coccyx and proceeding superiorly. At the level of
the sacral fascia, the fibro-fatty layer is cleared
over the gluteus major for 6 cm on each side. The
gluteus is incised and spread bluntly in line with
its fibers to a depth of about 3 cm between the
muscles – where the plane is not always well
defined. A pocket is made ending at the pyriformis
to avoid the sciatic nerve. General anesthesia
combined with muscle relaxants, are helpful, and
with strong retraction, the implant is positioned.
Good muscle closure followed by a midline repair
catching sacral fascia is essential. As in all
implant procedures, infection is the most feared
complication. I have had only one, and explantation
was required. Drains are not used; a binder or
postsurgical wrap is optional. Most patients are
more comfortable in the prone position
postoperatively. Recovery time varies, and walking
comfortably may be possible as early as 4 days or as
late as 2 weeks. Sitting forward, on the ischium, is
allowed at any time. Postoperative hygiene is
stressed. Full activity and exercise is expected at
4 to 6 weeks, but fluid collection of blood and
serum, indicated by lowgrade fever and sciatic
irritation, may delay this.

The Calves
An under developed lower leg can be a source of
embarrassment. This is even more true when it is
associated with asymmetry, congenital deformity (tibial
torsion, pes planus, genu valgus), trauma, or
disease. In some people, calf development fails to
respond even to strict exercise regimens.
Augmentation of the calves with subfascial silicone
implants ahs been practiced for more than 25 years
and is a reliable procedure, particularly with the
Aiache lenticular implant. Technique and accurate
selection of size bear heavily on the outcome.
The implants are placed through a transverse
popliteal incision in a plane dissected between the
gastroc fascia and muscle. A larger size is usually
used over the medial head. The septum, between the
gastroc heads and its neurovascular bundle, is
preserved. The implant must be seated at the bottom
of the facial sock, which envelops the gastrocnomus,
but care is taken not to destroy the toe of the sock
if the implant slips too low. A special paddle or
spade dissector aids in this maneuver. Small
branches of the sural nerve, especially in the
medial dissection, may be sacrificed. This can
result in temporary patches of numbness. The
incision is repaired with 3-O polyglycolic acid
suture for fascia and 4-O polypropylene suture for
subcuticular tissue. Gauze, 4x4s, and paper tape
dressing over surgical adhesive is provided, along
with a post surgical wrap. A moderately elevated
heel provides comfort.
With significant tibia torsion it may be advisable to
augment only the medial head to provide balance.
When the lower portions of the legs are thin,
augmentation of the calves alone may exaggerate the
deformity. I have used several techniques to fashion
more pleasing contours. Liposuction of the knees
and, at times, the lateral distal leg may be
combined with fat autografting to the lower medial
knee and medial ankle. Subcutaneous augmentation of
these areas, as well as the medial tibial areas has
been successful.
I have developed a combined medial, calf-medial, leg
sub-fascial silicone implant, which has met with
patient approval and no complications. The medial
implant has a rod-like fascial investment to augment
the leg just above the malleolus.
Ambulation is immediate to return home, but bed rest
with leg elevation for 2 to 3 days is necessary to
avoid seroma. Rapid return to weight training or
vigorous exercise before 4 weeks may result in
hematoma or seroma, which may require needle
drainage. Sudden expansion may result in tissue
breakdown. Dissociative or local anesthesia is
adequate for all calf and leg procedures.

Made to Order
In addition to the preformed pectoral, buttock and
calf implants, custom implants- made from moulage to
correct pectus excavation, trochanteric and other
contour deformities – are used. The area to be
augmented is outlined with a gentian violet pen and
petroleum jelly is applied. A powder and water mix
or premixed paste is applied and worked until the
desired contour is obtained. Having photos in the
standing position is helpful. When the moulage is
firm, it is gently lifted off, placed on a soft base
to dry and packed in a box with soft supports and
padding. Then it is sent to a facility, where a mold
is formed and a complete implant produced. Having
one or two small holes are helpful for orientation
and fixation.
Implant augmentation, when combined with liposuction
and body lifting techniques, demonstrates that the
era of true body sculpting has arrived.
