Augmentation
Mammoplasty
What
is it?
The cosmetic surgery which corrects small
breasts is called
Augmentation Mammoplasty. Women typically seek breast enlargement
to improve their self image and to look better both in & out of
clothing.
What causes it?
Lack or loss of breast
volume could be due to underdevelopment of breasts, weight loss, post
pregnancy or breast feeding.
How is it done?
Breast enlargement is achieved with the
help of a pair of implants inserted underneath the breasts. This is
a daycare procedure and does not require any hospitalization in most
of the cases.
Implant Selection:
Size: Size is determined by the
woman’s desire and the surgical possibilities. The size of the pocket
in which the implant is placed is determined by the size of the breast
and chest wall. The implant must fit comfortably into the pocket.
An oversized implant is not stuffed into a small pocket and a small
implant is not placed into a large pocket. The implant must fit the
breast. This will normally create a breast in keeping with the patient’s
built and chest wall size. Women who request breast size larger than
average will require exceptionally large pockets fashioned under the
muscle with subsequent insertion of an oversized implant. The result
may not be very attractive.
Type of Implants:
Basically there are two
kind of implant available for breast augmentation.
- Silicone gel Implants.
- Saline filled Implants.
Silicone gel implants
Until recently most physicians used
silicone gel implants, which are made of a silicone gel encased
in a bag made of a silicone elastomer. At a molecular level the
bag is distinguished from the gel by the amount of cross-linked
molecules. The bag has more of these molecules giving it a rubber
like texture. The purpose of the bag is to prevent the silicone
gel from coming into contact with the breast tissue. This kind of
Implant gives a very natural feel to the augmented breasts.
Saline filled
implants
Saline implants are currently the most
popular alternative. A saline implant is made of a salt and water
solution encased in a bag made of silicone elastomer. These implants
are not as popular because they do not look or feel as natural as
the silicone gel implants. The saline can also leak through the
silastic bag but is not implicated in the controversy because the
salt water is simply absorbed into the body. The only concern with
the leak is that the implant may decrease in size over time.
Implant Placement
The implant may be placed under the
breast tissue (subglandular augmentation mammoplasty) or under the
muscle (submuscular augmentation mammoplasty). The Submuscular technique
involves the insertion of an implant into a pocket created under
the muscle over which the breast sits and has been the preferred
technique for a number of years. The submuscular technique had been
more popular in the past because the breasts look and feel more
natural, have natural cleavage and the incidence of subsequent breast
hardening is dramatically reduced as compared to the subglandular
approach with the use of smooth surfaced implants
The submuscular implant however, has
drawbacks as well. There tends to be more discomfort immediately
after the surgery. On contraction of the chest wall muscle (pectoralis
major), the implant underneath the muscle is squeezed flat and pushed
sideways. Some women find this unattractive. Submuscular implants
affect the performance of such athletes as competitive swimmers
and professional weight trainers, who depend on the pectoralis major
muscle. Some muscular placement also gives unnatural feeling while
swimming as the breasts float separately from the implant.
More recently the use
of textured surface implants as reduced the chances of contracture
formation even with subglandular placement of implant. So this technique
has again come in popular demand as the subglandular approach gives
better feel of the augmented breasts.
Procedure:
The incision for breast enlargement
may be made in the inframammary fold under the breast where it attaches
to the chest wall, around the nipple (known medically as peri-areolar),
from the outer edge of the armpit (the transaxillary approach) or
directly across the nipple areola. The most common incision is a cut
4 centimeters (1⅟₂ inches) in length along the inframammary
fold. This makes it easy to create the implant pocket under the muscle,
does not disturb the breast tissue too much, and the resulting scar
is inconspicuous. The transumbilical technique places the incision
in the umbilicus or belly button. The pocket for the implant is created
through an endoscope and the silicone bag is out in place. The saline
solution is pumped into the bag to achieve the desired size and shape.
Once the implant is
in place the incision is usually closed with absorbable sutures
and skin tapes. It is then covered with a light dressing, and a
soft elastic bra is placed over the breasts.
Augmentation of both
breasts takes approximately one hour. The patient returns home in
the evening of the day of surgery and should be accompanied by an
attendant (driving is not allowed on the day of surgery). Some cases
are kept overnight in the hospital, for closer post operative monitoring,
and discharged the following day.
Post operative pain:
Some discomfort may be experienced over
the breast and the front of the armpit for approximately 3or 4 days.
This discomfort gradually subsides. By the seventh day most discomfort
disappears, although occasional shooting pains may be felt in the
breast area. This might occur for up to 6 months following surgery
but the frequency gradually decreases as the breasts heal.
Potential Problems
All the surgery has potential
complications. The degree of risk must be weighed with the desired
outcome. A breast augmentation can cause the following problems.
◆ Breast
Hematoma:
When blood collects
in the implant pocket it is called a hematoma. One or both breasts
swell and marked pain and tightness is felt as well. Any suspicion
of a hematoma, even if small, should be investigated by the surgeon.
If a hematoma is present, the pocket of the breast is reopened and
the blood is drained. As drainage occurs the breast becomes soft
again. If a hematoma remains untreated, a capsular contracture that
hardens the breast will almost invariably occur.
◆ Capsular
Contracture:
When a layer of fibrous
tissue surrounds or encapsulates the implant it is called capsular
contracture. Occasionally, excess scar tissue develops around the
implant resulting in a hard, often tender breast. This may progress
to the point where breast asymmetry occurs, necessitating a second
operation through the same incision to remove the fibrous tissue.
With the advent of submuscular augmentation, the incidence of capsular
contracture has markedly decreased. Approximately 1 in 20 women
(5%) will develop a firm breast capsule. The exact cause of breast
capsular contracture is unknown.
With submuscular breast
enlargements, most breasts that are soft at 6 weeks remain that
way, although a delayed fibrous contracture may develop in the odd
case. This is most likely due to an unrecognized hematoma in one
breast causing an increased amount of scarring around one of the
implants. To re-establish breast symmetry, surgical correction is
necessary.
◆ Decreased
Breast sensation :
It is common to notice
a change or decrease in breast sensation for the first 3 to 6 weeks
following surgery. Usually, normal sensation returns. Approximately
1% of women, however, will complain a permanent change in nipple
sensation. This is usually caused by damage to the nerves of the
nipple, which could be due to surgical injury or compression by
the impact or scar tissue.
◆ Infection:
This is such a rare
complication of breast surgery that most surgeon do not place their
patient on pre-or post operative antibiotics. It is possible that
a low grade infection around the implant is responsible for capsular
contractures, but this has not been scientifically confirmed.
FAQs:
◆ How
much big will the breast be?
Most women increase
one or two breast sizes; that is from a 34A to a 34B or C or from
a 36A to a 36B or C. A larger breast may be made if so desired.
◆ How soon
after surgery may activity be resumed?
Normal activity is
possible soon after a breast augmentation provided it does not cause
discomfort and pain.
Strenuous activities
should be avoided. Patients who do not heed this warning experience
much more discomfort and run the risk of developing a hematoma in
the implant pocket. A gradual buildup to a full range of activities,
such as aerobics, jogging, and swimming, may take place over a 6
week period.
Women who lift weights
should avoid pectoral curls or other exercises using the pectoral
muscles, as this may tear the scar tissue which forms around the
pocket after the incision heals. Vigorous stress on these muscles
may cause of the muscles to tear, resulting in capsular contractures.
A car may be driven
the day following surgery, although a standard shift is often uncomfortable
to use. There is no restriction on flying.
◆ Is breast-feeding
still possible?
Both submuscular and
subglandular breast implants are behind the breast tissue, which
means they are out of the way of the breast’s most important function,
that of nurturing a baby. The breast responds to pregnancy induced
hormones and enlarges and produces milk. With the increased volume
and stretching of the breast during pregnancy, some loss of breast
posture may occur, just as it does in the breast which is not augmented.
◆ How long
the implant remain in the body?
The implant is medically
inert and remains intact for longer than human tissue. The breasts
continue to age, with a gradual loss of tone. The scar tissue around
the implant, in fact, may actually act as an internal bra, providing
some support to the breast. These days the recommendation from the
manufacturers is to change the implant every 10 years.
◆ What
can be done about hard and unattractive implants?
The only treatment
now a days is open capsulotomy. Here the implant is removed through
the incision of the original surgery. The scar tissue that has enclosed
or encapsulated the implant is opened and partially removed. The
implant is then reinserted.
Closed capsulotomy
, which is non-surgical method is an outdated procedure these day
as the implant rupture rate was unacceptably high.
◆ Do breast
implants cause Cancer?
Currently there is
no scientific evidence to suggest that the incidence of cancer increased
with the introduction of implants into the breasts.
◆ Will
it still be possible to detect cancer after an augmentation?
Breast augmentation
does not increase or decrease the incidence of breast cancer. In
the case of subglandular implant, some breast tissue atrophy and
thinning occurs from compression of the implant on the breast substance.
This makes detection of masses or cancer on standard mammography
techniques must be used. With submuscular implants, there is a minimal
amount of thinning of the breast tissue. Therefore, concern over
cancer detection using standard mammography is less of a problem.
Another advantage of submuscular augmentation is that a breast biopsy
may be performed without disturbing the implant is often damaged
during a biopsy due to its more superficial location.
◆ Will
an augmentation rid the breast of stretch marks?
Stretch marks cannot
be eliminated by enlarging the breast, although they often appear
less noticeable because the stretch marks are flattened over the
larger breast mound.
◆ What
are the alternatives to surgery?
The only alternative
is to wear a padded bra. Exercise will not increase the breast size
itself. The muscle beneath the breast will enlarge with certain
types of exercises which, in effect, increases breast projection
but not breast size. Any other external techniques to increase the
breast size as is advertised do not offer any effective solution
and are highly misleading.
- What is the controversy associated
with Silicone Gel Implants
?
The phenomenon of silicone
gel bleed is being the subject of studies which has caused lots
of concern amongst the users as well as the plastic surgeons. This
phenomenon is the result of microscopic leakage from the
implant surface. This leaves a slight film of gel on the outer surface
of the implant known as a silicone bleed. In the newer generation
of implants, the amount of silicone bleed has been significantly
reduced by increasing the thickness of the bag. There are some question,
however, as to whether the bag itself also sheds silicone into the
body over time as it gradually deteriorates. Nothing has been proven
for or against this phenomenon and the amount of damage it can cause
to the body.
It has been suggested
that the introduction of silicone into the body may play a role
in human adjuvant disease (HAD), which is implicated in such conditions
as rheumatoid arthritis, systemic lupus erythematosus, dermatomyosities,
polymyositis, and perhaps even chronic fatigue syndrome. At present
a definitive causal relationship has not been established and the
current data would suggest that there is no relationship. However,
as with all statistics, the data can be interpreted to either support
or refute the claims that silicone contributes to HAD and hence
the controversy.
What we do know for
sure is that the silicone bag definitely become week with time and
based on various studies the manufacturers are now recommending
the replacement of these implants every 10 years.
