Breast augmentation is not a one-size-fits-all surgical enhancement. There are different types of breast implants, as well as different shapes and sizes. But how do you know which breast implants are best for you? In this article, I explain how I guide you in each of these areas so you can make an informed decision.

Which breast implant size is best for you?

Choosing the right breast implant size is an important part of the decision-making process. During your consultation, we will explore various size options that align with your body proportions and personal goals.

Breast implants are measured in cubic centimeters (cc) and you can choose from as little as 80cc to 800cc. The higher the number, the larger the implant.

Sizing is done in the consultation rooms after measurements of the chest wall and breastplate width and height (that is the surface area that the breast occupies on the chest wall).

Depending on your body measurements, the amount of natural breast tissue and the current size of your breasts, we discuss several ‘best’ breast implant size options. Your input is valuable and highly appreciated. My goal is to help you achieve your ideal bust line in a safe manner.

Bigger isn’t always better. For example, a 350cc implant may be considered a large implant for a petite patient with a smaller breastplate width. A common misconception about breast augmentation is that a larger implant is always necessary to achieve a desired look. The best results depend on individual body proportions and personal preferences.

Different types of breast implant shapes

Choosing shapes

There are two main breast implant shapes:

Round
Anatomical or tear-drop.

Both designs create a different look.

Characteristics of round breast implants:

Circular
Provide excellent augmentation of the breast envelope
Allow for rotation or malposition given the 360 symmetry of the implant.

Round breast implants are some of the most commonly used implants.

Characteristics of anatomical breast implants:

Anatomical or tear-drop implants have a natural shaping to them to provide a sloped gradient across the implant. This is useful in cases where patients with low breast volume want a more natural proportioned appearance.

Best type of breast implants

Different types of breast implants

At my plastic surgery practice, we use TGA*-approved, medical-grade sillicone breast implants. There are a few brands available for use.

The reason we use these particular implants is first and foremost because they are TGA- approved and safe for use in patients. They also allow for many subtle variations in the size and shape and contour which allows discrete customisation of the implant for the patient.

Breast implants do not have an expiration date, but they may require monitoring over time. Replacement is typically considered if there are clinical concerns or at the patient’s request.

You may have heard about the risk of BIA-ALCL (implant associated anaplastic large cell lymphoma). It is a condition which occurs most frequently in women who underwent breast augmentation after receiving particular textured breast implants. The TGA now has removed the highest risk implants from the market. The implants used in our practice are TGA-approved. During your consultation, we will discuss any potential risks, including BIA-ALCL, to ensure you are fully informed.

Given the complexity of this topic, it is best we discuss it in person during your consultation. If you are a GP and you have questions related to this topic, I can provide clinical guidelines. Further detailed information can be found at the TGA’s website.

Best placement for breast implants

Breast implant placements

You may have come across terms like “under the muscle” or “over the muscle” and “dual plane”.

Submuscular breast implant placement means an implant is placed under your chest muscle and under the glandular tissue. As a result, the implant is well covered and well protected.

Subglandular breast implant placement means the implant is placed under your breast tissue and over your chest muscle.

Whether it is under or over the muscle, both locations can produce satisfactory results. However, there are pros and cons to each option. As with breast implant size and shape, I will assess your unique body type to determine which location is best for you.

Dual plane refers to partially locating the implant underneath the muscle as well as some glandular tissue. The concept is that it allows some significant muscle coverage of the implant with the benefits of shaping that the glandular tissue allows.

So which placement technique is best for you? The main factors that will play a role in the implant placement decision making are:

patient safety
whether the case is a primary augmentation or revision
the type of breast surgery (reconstructive versus cosmetic)
the various patient characteristics (skin quality, breast volume, previous surgery or trauma to the site).

Breast augmentation recovery Brisbane

Recovery after breast augmentation surgery

Recovery following breast augmentation varies between individuals and is supported by our team to ensure the best possible healing process.

Some swelling and tightness is common in the early stages of recovery. These effects typically subside over several weeks as the healing process progresses.

Over time, implants may gradually settle into their final position as part of the healing process. The ‘squared’ look will naturally subside giving you a new softer more natural appearance.
