Breast Augmentation with Implants

Adding Volume to Change Breast Size and Symmetry for Los Angeles, Beverly Hills, Santa Monica, and Beyond

Breast augmentation with implants has been the most popular cosmetic surgery procedure in the United States for years—likely because there are many reasons a woman may not be happy with the look of her breasts. Whether the problem is a lack of volume, noticeable asymmetry, changes in breast shape, or a combination of the above, it can be very upsetting. Our surgeons offering breast augmentation at the Los Angeles area's Cassileth Plastic Surgery are industry-leading experts on implant-based augmentation, customizing each surgical plan to meet individual patients' bodies and goals.

As women, we know the importance of feeling confident in our bodies. By working closely with each breast augmentation surgery patient and carefully choosing the ideal implant size, shape, and projection, we can create a natural-looking breast that has added volume and improved symmetry. It's not just about being "bigger"—it's about creating the image you want the world to see each day.

Patient Testimonials

Anonymous' Story

After a year of contemplating, researching and having over 5 consults I finally decided to get a breast augmentation last October 2016 with Dr. Killeen. I was very nervous leading up to the day of surgery. Dr. Kileen and her staff has been exceptional. Jade the office manager was attentive and always answered my questions. I have to say I am a very neurotic patient and need a lot of handholding when it comes to surgery. Dr. Kileen is an excellent surgeon and she assured me that would give me natural looking breast with the volume I was looking for. I went from 32b to 32 d. I am 3 months out from surgery and all my friends say I look great. I am glad I finally did it.

What Does Breast Augmentation Surgery Entail?

Breast augmentation surgery starts with a consultation to determine procedure specifics. One of the most important elements to consider is implant size, type, and profile.

Saline breast implants are filled with salt water. Many women feel that these implants have a balloon-like feel and look, and most women prefer silicone implants because they feel more like real breast tissue. Standard silicone implants are thick and jelly-like in consistency, with a soft, amorphous shape. Highly cohesive silicone implants are firmer, like a gummy candy in consistency, and hold their shape, hence the nickname "gummy bear implant."

Breast augmentation in Los Angeles at Cassileth Plastic Surgery involves positioning the breast implant either above or below the chest muscle. Breast augmentation in Los Angeles at Cassileth Plastic Surgery involves positioning the breast implant either above or below the chest muscle.
One of the decisions impacting every breast augmentation procedure at Los Angeles' Cassileth Plastic Surgery is implant placement. The device may be inserted in a subglandular position (in a pocket above the chest muscle) or submuscular position (in a pocket below the chest muscle). Each technique has unique benefits, with the right choice depending on the patient's individual circumstances and preferences.

The surgery itself involves several steps: creating a small incision, inserting the chosen breast implant to make the breast appear larger, and closing the incision.

At Cassileth Plastic Surgery, we routinely position the implants in a pocket made under the pectoral muscle. Our highly skilled breast surgeons prefer this subpectoral position for several important reasons: Implants inserted below the muscle stay in position longer, have less visible rippling, enjoy lower complication risks, allow for more accurate mammograms, and offer a more natural-looking appearance.

What Can Breast Augmentation Do?


Many women whose breasts have lost volume over time want to restore their breasts' natural fullness with breast augmentation. Others choose the surgery to add volume to breasts that have been smaller than desired ever since they first developed. Breast implants are available in a wide range of sizes, allowing for anything from modest to dramatic results.


Breast augmentation surgery can create a fuller, more attractive breast shape for women with small breasts, and for those who have lost breast shape and volume due to weight loss or breastfeeding. Breast augmentation can also change the shape of naturally tuberous breasts.


Breast augmentation can correct breasts that are different sizes or shapes from each other. Most women naturally have some degree of breast asymmetry, though the difference in the breasts is typically not very obvious. In some women, however, the asymmetry is more noticeable, whether due to genetics, natural development, birth- or nursing-related changes, or trauma. Our plastic surgeons specializing in breast augmentation surgery can create beautiful, symmetrical breasts and improve their overall appearance and positioning.

Are There Options Besides Breast Augmentation with Implants?

Fat transfer breast augmentation is a technique that uses a patient's own fat cells, instead of implants, to add volume. This surgery is ideal for women who want a more modest increase in size. Harvested fat can also refine the results of augmentation with implants.

In some cases, breast asymmetry or changes in shape or position may be due to sagging. A breast lift is designed to correct this problem by removing stretched-out skin and securing the breasts for a more elevated look.

Breast augmentation and other breast and body procedures can be combined with each other, as well as non-surgical treatments, for a Mommy Makeover. This customizable collection of services can address changes caused by pregnancy, childbirth, and nursing.

Women who have chosen breast augmentation with implants in the past, but who now want to make a change, can choose implant revision or implant removal.
