One of the most personal decisions you'll make during your breast augmentation journey is choosing the right implant size. While there is no universal right answer, the right choice is one that flatters your natural proportions, suits your lifestyle, and helps you achieve your desired look.  

Whether you have a flat chest and are looking for a significant increase in volume, or you want to enhance your current shape, the selection process is about more than picking a cup size. It's a detailed decision best made with an experienced surgeon. At Kansas City Surgical Arts, Dr. Matthew Hlavacek guides patients through the selection process with personalized advice at each step.

What is breast augmentation surgery? 

First, what is breast augmentation surgery? It's a custom procedure that can increase the size or improve the shape of the breasts. Surgery is done using general anesthesia and involves placing medical-grade implants either above or below the chest muscle. Beyond addressing a flat chest or enhancing overall proportions, breast augmentation surgery can also restore volume lost after pregnancy, breastfeeding, or weight loss. 

How we determine the right implant size 

Cup sizes are a helpful starting point for describing your goals, but they are not how implants are measured or selected. Breast implant size is measured in cubic centimeters (CCs) of volume, and the choice depends on several factors. Here is what Dr. Hlavacek considers during the selection process:  

  • Your natural anatomy: Chest width, existing breast tissue, and skin elasticity all play a role in determining which implant sizes and profiles will look natural on your frame. 
  • Your lifestyle: Patients who are very active or athletic may find that a moderate size feels more comfortable and practical for their daily routine. 
  • Your aesthetic goals: Communicating clearly about the look you are going for helps narrow down the options significantly. 

Silicone implants vs saline implants 

Silicone implants are a commonly chosen option for breast augmentation surgery. These implants are filled with a silicone gel and mimic the feel of regular breast tissue. Saline implants are another option and offer the advantage of being adjustable in size during surgery. However, many patients find that silicone implants deliver a more natural result. Dr. Hlavacek will walk you through the differences during a one-on-one consultation so you can make an informed decision. 

Making the choice 

Selecting the right breast implant size is ultimately a collaborative process. At Kansas City Surgical Arts, Dr. Hlavacek uses a combination of detailed measurements to help you determine a cup size that feels right for your body and lifestyle. Patients are encouraged to bring photos of results they admire to their consultation, as visual references can be helpful for communicating the look they are going for. The goal is always a result that feels natural, proportionate, and what you envisioned.
