| Breast
Expanders / Implants |
|
| For most patients, one of
the first major decisions after deciding to proceed with reconstruction
is deciding between breast reconstruction using their own
tissues (various types of flaps) or using implants. There
are advantages and disadvantages to each approach. In some
cases it may be necessary to use implants with muscle or tissue
flaps (see Flap Reconstruction
With Implants).

What are Expanders and Why Are They
Used?
|
| For many patients,
after the mastectomy there is not enough skin or tissue around
the breast to allow for immediate placement of a breast implant.
For those patients, the first stage of surgery is to insert
a tissue expander. A tissue expander is very similar to an
implant except that there is only a small amount of fluid
inside it initially so it is quite flat.
After the patient's incisions heal from that
first stage of surgery, the doctor begins the process of expansion.
This involves the patient coming to the office every 1-2 weeks
for expansion. At each office visit the doctor uses a needle
to insert saline into the expander to increase its size. As
the amount of saline increases in the expander and it increases
in size, the skin covering the expander stretches also. Each
of these visits typically takes 10-15 minutes and patients
usually find the expansion to be relatively painless.
Eventually, the expander reaches the size
the patient desires and now there is sufficient skin available.
The second stage of surgery then takes place in which Dr.
Duffy removes the expander and replaces it with a permanent
implant. |

What
Types Of Implants Are There? |
There
are basically two types of implants available to choose from
- saline and silicone. Silicone implants can only be placed
by surgeons who participate in one of several adjunct studies.
Dr. Duffy participates with the Mentor adjunct study and is
therefore able to offer his patients the choice of either
saline or silicone implants.
Saline implants are actually implants made
of a solid silicone shell and filled with saline. Silicone
implants are made of a solid silicone shell and are filled
with silicone gel. Many patients have heard about "cohesive
gel" implants. All the silicone gel implants utilized
by Dr. Duffy from Mentor are cohesive gel implants. This simply
means the gel filling the implants is of a very thick consistency
and acts as a unit rather than a liquid. It holds together
uniformly. The choice of which implant to use is made by the
patient with Dr. Duffy's input. Dr. Duffy provides his patients
with information regarding the safety of implants and the
differences between the implants.
In addition to choosing silicone versus saline,
there are also different shapes of implants. For the vast
majority of patients, a round implant or high profile implant
is most appropriate. Dr. Duffy works with each patient to
recommend the best shape of implant to meet that patient's
needs. |

What
Are The Advantages And Disadvantages of Implant Reconstruction? |
Advantages:
|
- The recovery from the initial expander placement surgery
is usually quicker than flap surgery.
- It may be easier to control the final size of the reconstructed
breast with implant reconstruction.
- There are no additional scars on the patient's body other
than those on the breasts.
|
| Disadvantages: |
- Because most patients require placement of an expander
first followed by secondary replacement of the expander
with an implant, this requires at least 2 surgical stages
and multiple visits to the plastic surgeon's office between
these stages for tissue expansion.
- It is important to realize that for patients who are having
a unilateral (one-sided) mastectomy, matching the contralateral
natural breast with an implant can be difficult. The shape
and "feel" of an implant is not exactly like that
of a natural breast.
- In the short term, implants can become infected or malpositioned
and require surgery to correct these problems.
- In the longer term, implants can develop capsular contracture
(tightening of the soft tissues around the implant), implant
malposition, and implant rupture. All of these can require
secondary procedures.
