Implant Placement- Subglandular versus Submuscular

Main Points

     
  • Is there a particular shape you want to achieve? Is there one you want to avoid?
  • Does ease of ability to feel the implant bother you at all?
  • Remember "Rippling" from the last topic? How do you feel about rippling?

Subglandular placement:

The implant is placed beneath the breast tissue and skin over the Pectoral musclature..

Submuscular Placement:

The implant is placed beneath the Pectoralis major muscle as well as breast tissue and skin. This is commonly called "Under The Muscle."
 
 

A Subglandular Placement Example:

This image shows the result of a mid-sized implant placed in the Subglandular position. The young lady presented to my office one year after her first breast augmentation operation using saline implants  (by another surgeon). As she was displeased following the surgery, she went back to the original surgeon four months following the surgery. He responded by making the implants even larger and leaving them "Over The Muscle." Let us analyze the aesthetic problems here:

     
  • The implant's margins are very visible here especially toward the cleavage.
  • Even though the patient is only one year from surgery, the breast "mound" has already descended objectionably leaving the nipple and areola positioned "too high" on the mound. This is far more commonly seen in subglandular implants as the Pectoralis major muscle (in the Submuscular case) supports the implants to an extent retarding extreme descent.
  • The cleavage is poorly-developed even though the patient is displeased that the implants are too large. Usually larger implants develop the cleavage better.
Here is the same patient ten weeks later. The old implants were removed from the subglandular pockets and replaced with smaller saline implants, which were placed beneath the Pectoralis major muscles. A modified breast lift was performed to reposition the nipple and areola correctly on the new breast mound. The patient's breast look more natural and the cleavage is better developed. This was a fair bit of work leaving the patient looking almost as nicely as she would have if a submuscluar placement had been performed at the first operation. 
 

Summation

On the topic of rippling, saline-filled implants can ripple because of the "thinness" of water. Rippling is more apparent where the implant is covered by little tissue. The more tissue covering the implant in any region, the less the tendency for rippling to be visible through the skin. Even with Submuscular augmentation, rippling can show underneath the implant and/or at the sides of the chest where the tissue covering is the least abundant. With Subglandular placement, rippling can be apparent over the entire chest including the cleavage probably the worst potential place for it to show. This patient had rippling toward the cleavage prior to surgery when she walked. This was improved following corrective surgery (above).

To date, no patient with sub-muscular implants has requested that her implants be replaced in the subglandular position. There are several patients like the one above that requested the opposite.
