Breast augmentation is possible without placing a scar on the breast. It
is possible to insert implants through auxiliary incisions or as is my
preference through an incision in the "belly button"- the transumbilical
breast augmentation (TUBA). In this approach, the patient is anesthetized,
an incision is made around the lip of the umbilicus, and a tunneling instrument
is used to create a channel between the umbilical incision and the undersurface
of the breast tissue. On the chest wall, under the breast tissue, a pocket
is created and inspected by insertion of the endoscope. Any area of bleeding
is electrocauterized, and the pocket is enlarged to accommodate an implant.
The endoscope is removed. The implant is evacuated and rolled tightly into
a cigar shape. A long fill tube is connected to the implant, and the implant
is worked up through the channel to lie in position behind the breast tissue.
The implant is filled with saline, the fill tube is removed and endoscopic
inspection performed to confirm proper position.The small incision in the
umbilicus is closed and an occlusive dressing applied. The patient is discharged
after a short recovery. She is able to be up and active the day of surgery,
and may even shower the night of surgery. Activities are restricted only
by the degree of discomfort which in most cases is mild to moderate.
A discussion of the various possible complications
including the risk of the use of silicone is beyond the scope of this presentation.
When I see a patient in consultation, I spend at least an hour with the
patient and give them a voluminous packet of educational materials to take
home. Suffice it to say that the major, real problem relative to breast
augmentation is development of capsular contracture. A brief discussion
of capsular contracture is follows:
Whenever any foreign body is placed under the
skin, whether it be the lead of a pencil,a pacemaker, a bullet, or a breast
implant, scar tissue forms around the foreign body. This is the body's
way of separating that foreign body from itself. In cases where the foreign
body is solid, such as the pacemaker or bullet,no matter how dense the
scar tissue becomes there is no significant effect.In the case of a breast
implant, if a small or moderate amount of scar tissues present then no
disturbing result occurs. If however, dense scar tissue forms around the
implant then the implant can be deformed, some pain can occur and the breast
will feel hard, and the implant may be drawn into an abnormal position.
Why some women develop more scar tissue than others is unknown, and why
one breast or the other may be involved but not both is unknown. Many theories
have been advanced, and many attempts to decrease the chance of capsular
contracture have been instituted. Nevertheless, some degree of capsular
contracture may occur in up to 20% of patients. This sounds like a high
percentage, and indeed it is, but capsular contracture is graded one, two,
three, and four, and grades one and two usually require no surgical intervention.
When treatment is instituted, it includes massage and anti-inflammatory
medications. Often fully developed contracture is avoided. For this reason,
close and frequent monitoring of the patient and early institution of treatment
postoperatively is required. If a capsular contracture is more severe,
it may require surgical excision, if there is pain and deformity. In that
event, the capsule will be removed and a new implant inserted. Redevelopment
of capsular contracture can indeed occur, but of course is not inevitable.
Usually the onset of capsular contracture is fairly soon after insertion
of the implants but it can occur even years later.
Other complications of breast augmentation include
bleeding, scarring, infection, deflation of the implant, change in nipple
sensitivity, rippling of the implant, and palpability of the implant. These
in aggregate are much less frequent than the development of capsular contracture.
Capsular contracture is the most frequent serious complication and should
be considered a very real threat, not to be taken lightly. It does occur
and it does cause problems.

Note that there are no breast scars and the scar of the umbilicus is unobtrusive
and easily hidden.
