Yes, breast implants placed over the muscle (subglandular) often appear larger and fuller immediately after surgery because they sit higher and closer to the skin, without muscle compressing them; however, under-the-muscle placement can look smaller initially due to muscle coverage, but eventually settle to a natural size, making the perceived size difference dependent on tissue, swelling, and healing.
Women who have implants placed over the muscle tend to have less post-operative discomfort because the chest muscle is not manipulated during surgery. Also, leaving the chest muscle intact means there is no risk of the implants visibly distorting when flexing the chest muscle during exercise or daily movements.
For women desiring a more natural breast augmentation, an under the muscle placement is often the right choice for them.
Because the saline implant is easier to detect by sight and feel and the muscle offers additional coverage of the upper half or two thirds of the implant, saline implants are generally placed under the muscle. Gel implants, because they are harder to detect, can go over or under the muscle.
How many ccs do you lose under the muscle? Patients can lose anywhere between 30 to 50 cc. Surgeons usually recommend going a size up to make up for this difference.
Implants that are placed above the muscle (subglandular placement) typically drop faster than breast implants placed under the muscle (submuscular placement).
In most cases, a cup size bra is equivalent to 150 to 200 cc of breast implant size. If you want to increase your bra size from an A cup to a B cup, you'll need an implant size of at least 200 cc. If you want to go from a B cup to a D, you'll need an implant size with 300 to 400 cc.
Cons of Over the Muscle Placement
Many patients who receive breast implants half under the muscle say their results feel soft, move naturally, and look indistinguishable from natural breast tissue. In our practice, this technique often plays a key role in both cosmetic enhancement and restoring confidence after breast cancer.
Just as thinner women with less breast tissue may be better candidates for submuscular placement, women who have very large and/or strong chest muscles are better suited for over the muscle implant positioning.
Silicone Breast Implants
Known for their soft, breast-like consistency, silicone implants provide a look and feel that is closer to natural breast tissue than traditional saline implants. Available in a variety of shapes and profiles, they can be customized to complement each patient's body and aesthetic goals.
In these situations, if the implant is placed under the muscle (which is high on the chest), then the implant will be high, and the breast will droop over it. This is called a “waterfall deformity” or “Snoopy deformity” (named after the cartoon character's profile). This is not a desirable look.
Natural look: The biggest benefit of submuscular placement is that it typically offers a more natural-looking result, particularly in the upper portion of the breast. Another potential advantage is that submuscular implants may have a more gradual, natural slope, which many patients prefer.
Submuscular placement
This technique includes placement of the implant partially under the pectoralis major chest muscle. PROS: Patients experience more accurate mammograms. In addition, the submuscular placement tends to produce a more natural appearance, and a reduced rate of capsular contracture.
Placing implants over the muscle creates a tight sensation but doesn't cause the more painful muscle soreness that comes with placing them under the muscle. Although you may feel a bit uncomfortable for up to two weeks, most patients report that any actual pain is fully resolved within five to seven days.
There's no single "most attractive" breast shape, as beauty is subjective, but studies often point to a "teardrop" or "natural" shape with a 45:55 upper-to-lower pole ratio (more volume below the nipple) as a common preference in scientific research, combined with a skyward-pointing nipple and gentle upper slope, aligning with principles like the Golden Ratio for natural proportionality, though different shapes like rounder or fuller upper poles are also favored.
According to Men's Health, the biggest tipoffs that men look for to determine if a woman has had breast augmentation surgery are based on sight alone. Indicators include the breasts being too close together, appearing abnormally large, or sitting too high on a woman's torso.
Your breast implants may appear to be bigger or fuller once they've dropped to a lower, more natural-looking position on your chest and "fluffed" into a rounder and softer shape. Changes in the size or shape of your new breasts after augmentation can also occur as swelling and tightness subside.
"One of the first things I tell them is 'This implant is not permanent and it will inevitably fail and have to be changed. ' It's remarkable how many people aren't aware of that." Did you know that implants don't last a lifetime?
The "45 55 breast rule" refers to a widely studied aesthetic ideal where the breast volume is split with 45% in the upper pole (above the nipple) and 55% in the lower pole (below the nipple), creating a naturally sloped, teardrop shape rather than a round, full look. This ratio, established by plastic surgeon research, is consistently rated as most attractive by men, women, and surgeons across different demographics, supporting its use as a benchmark in breast augmentation for natural-looking results.
Placing the implant below the muscle does typically make the implant look slightly smaller as the muscle will give the implant a touch more of a natural slope. It also compresses the implant, which makes the breast look slightly smaller.
350cc implants are considered a moderate augmentation, ideal for those seeking volume without losing body harmony. They are not considered excessively large, but they offer a visible transformation that enhances the neckline. The perception of the final size also depends on the patient's height, weight and chest width.
34B Bra Size: This is often called a “standard” B cup. Fits women with an average ribcage and moderate bust volume. One of the most common sizes.
