FAQs About Breast Implant Placement

The overall result of breast augmentation surgery is largely affected by implant placement.  To better understand this issue, the California Surgical Institute has provided a list of most frequently asked questions:

1.  Question:  What are the three basic types of breast implant placement?

Answer:  The implants can be placed under the tissue (subglandular or over-the-muscle placement), behind the muscle (submuscular or under-the-muscle), and behind the tissue and partially under the muscle (partial submuscular placement).

2.  Q:  What is the most ideal implant placement?

A:  The most ideal implant placement is dictated by a patient’s overall anatomical features including the amount of tissue and fat to work with, and her goals and expectations.

 3.  Q:  When is subglandular or over-the-muscle implant placement ideal?

A:  In general, this breast augmentation technique is ideal for women with ample amount of tissue and fat that provides enough “coverage” to prevent visible and palpable wrinkling.  And because the top edge of the implant has little tissue, the method provides a distinct cleavage line.

4.  Q:  When is submuscular or under-the-muscle implant placement ideal?

A:  The technique is highly ideal for patients with little amounts of tissue and fats who are prone to wrinkling and rippling.  Also, many plastic surgeons believe the implant placement is recommended for women who are concerned with sagging or bottoming out since the weight of the implant is supported by the muscles rather than by tissue and skin alone.

The submuscular placement is also ideal when using large breast implants (e.g., full D cup) because it prevents visible and palpable rippling.

To further reduce the risk of rippling, doctors recommend silicone implants, which are filled with a cohesive gel notable for simulating the feel of breast tissue and fats.  By contrast, women with little tissue are often advised to stay away from saline implant due to its watery consistency, thus increasing their risk of wrinkling.

Using smaller implants when dealing with small-breasted women is another effective way to reduce the risk of rippling and wrinkling.

5.  Q:  Is it true that women with submuscular implant placement can go braless without having to worry about sagging?

A:  Technically speaking, the answer is yes.  However, many plastic surgeons believe the breasts still need a good support to prevent or at least postpone sagging.

6.  Q:  Why is it that submuscular implant placement often results to longer recovery and more postoperative pain and discomfort?

A:  In this technique, the muscle is literally compressed and pushed by the breast implants, leading to more swelling, pain, discomfort, and longer recovery than if the subglandular implant placement were used.

7.  Q:  How long does it take for the implants to settle naturally?

A:  If the submuscular implant placement were used, it would take longer (several weeks or even months) for the implants to settle down naturally than if subglandular technique were used.  But regardless of which method is used, patients should expect that their newly augmented breasts will appear unusually firm and that they will sit higher on the chest.

Within a few weeks or months, the breast implants will settle downward, leading to a natural appearance.  In some cases, a strap is wrapped around the chest area to achieve a more desirable result.

8.  Q:  Does implant placement affect the rate of capsular contracture or tissue hardening?

A:  Some plastic surgeons believe that submuscular implant placement somewhat reduces the risk of capsular contracture because it limits the contact between the implant shell and tissue where most of the bacteria live.

However, this is just an anecdotal observation rather than a scientific conclusion.  And to put it succinctly, capsular contractures are quite unpredictable and may happen to some patients, regardless of which breast augmentation technique is used.

9.  Q:  Does implant placement affect the accuracy of breast screening test?

A:  In general, breast implants—no matter what type of placement is used—make it more challenging to perform breast X-ray and mammogram.  Fortunately, many radiologists nowadays have experience screening women with these devices.

Most experts agree that the submuscular implant placement is less likely to obscure mammogram readings than the subglandular technique. 

10.  Q:  Does a certain implant placement prevent symmastia or “uniboob?”

A:  The implant placement will not affect a patient’s risk of symmastia, a condition in which the breasts settle in the middle of the chest.  This problem happens if the implants are “inappropriately” large or there is over-dissection of the muscles at the breast bone.

As with any problems caused by implant displacement, symmastia can be only treated with revision breast augmentation surgery.
