Saline vs. Silicone: Which Implant is Right for Me?

Metro Vancouver women interested in breast augmentation need to make a number of decisions regarding their breast implants. These important choices include the selection of breast implant volume & projection, the final location or pocket placement of their implant and where they would prefer their incision to be made. One key decision patients must also make is which implant filler material they want: silicone or saline. Dr. Mosher will help you during your consultation and will make a recommendation based on your desired outcome and anatomy.  However, the choice is highly personal and is the patient’s decision to make.  

In some ways, the type of implant decision has been simplified as there are now fewer devices to choose from today than there were just a few years ago. The longer term risks associated with texturing on the surface of breast implants has resulted in most anatomically (tear-drop) shaped breast implants and some round implants being withdrawn from the market. At YES Medspa & Cosmetic Surgery Centre we only offer Health Canada-approved, smooth surfaced, round implants for cosmetic breast augmentation. Whether you are choosing implants filled with cohesive silicone gel or saline, know that your implants were designed with your safety in mind and each have a long track record of achieving high levels of patient satisfaction.

Saline Implants:

Saline-filled implants have been available for more than 30 years. These devices have the same medical-grade silicone shell as cohesive silicone gel filled breast implants. Saline filled breast implants come in an extensive range of dimensions but every device has a round shape. The base width and the implant projection determine the recommended fill volume of each device and during surgery saline (aka. sterilized salt water) is used to optimally fill the device. Saline filled implants when manufactured, are filled with air. In the operating room, a valve on the device allows your surgeon to remove the air and then fill the device with sterile salt water using a closed filling system that prevents the saline from being exposed to the air in the operating room. Each saline implant has a small range of volumes recommended for peak performance of the device and this allows for further customization of the final implant dimensions during surgery.

Saline implants may be right for you if:

  • You have enough of your own natural breast tissue.

Since salt water filled implants have very different tactile and movement characteristics compared to breast tissue, thin chest and breast tissues may not adequately camouflage these “water balloon” features. Although all breast implants can have some degree of rippling of the outer shell contours, saline filled implants with rippling can be more easily felt and seen compared to those that occur in cohesive silicone gel filled devices.  These problems are magnified in patients who choose to have implants that are larger, when implants are placed in front of the muscle and in patients with thinner tissues.  For patients with enough tissue to completely cover the implant and for those who desire a more natural looking final breast size and shape, saline implants can be an excellent choice.

  • You are under 22 years old. 

Saline breast implants are FDA & Health Canada approved for patients 18 years and older. Silicone breast implants are only FDA & Health Canada approved for patients over the age of 22 years. This discrepancy is a result of the regulatory history of breast implants and is not related to safety. For patients between the ages of 18 and 22 years old, silicone implants can be considered after discussion with your surgeon. When these are selected, the devices will be used “off label”. The main consequence of this decision would be that the manufacturer does not need to honor the device warranty when it is used “off label”. This is an important consideration as all implants will eventually rupture and need to be removed or replaced. About 10% of saline and gel implants will rupture in the first 10 years after surgery.

  • You want to avoid the need for medical imaging to check on your implants.

Implant manufacturers and regulatory agencies recommend silicone gel filled implants be checked every couple of years using Ultrasound or MRI imaging. We currently recommend an examination and possible imaging of the implants with any significant change to the look or feel of your augmented breasts. The current FDA guidelines for monitoring of silicone filled implants is to consider an MRI or High Resolution Ultrasound 5-6 years after the surgery date and then every 2 years even if the breast continues to look and feel normal. Alternatively, imaging of saline filled implants is rarely needed to confirm a rupture or leak. When these devices rupture it is usually quite obvious because most of the implant salt water fluid will be resorbed and the breast size and shape will appear deflated within several days or a few weeks.  

  •  You prefer the concept of a saline filled implant.

 Although there is no medical evidence that a ruptured or leaking implant causes any health concerns, some women prefer knowing that only sterile salt water is inside their implants.

Silicone Implants:

The most common breast implants selected by patients worldwide are those filled with cohesive silicone-gel. Currently, silicone gel implants approved in Canada are manufactured by one of two companies – Allergan and Mentor. Each company has smooth, round implants of varying width, projection and volume. These devices are believed by most, to better mimic the feel and movement of natural breasts when compared to saline filled implants. The firmness of the silicone gel within each manufacturer’s implants is different and occasionally Dr. Mosher may feel that one brand of implant should be considered over another. Satisfaction is equally high when Allergan or Mentor silicone implants are used. Although the term “gummy bear” implants has become popular, it is not accurate.  The cohesive gel fillers utilized are much softer and much less solid feeling than that of this popular candy. Dr. Mosher will share his 25 years of breast implant surgery experience with you when recommending an implant brand, style, width, volume and projection.

Silicone implants might be right for you if:

  • You want a more natural feeling breast.

This is particularly applicable to patients who have very little natural breast tissue and for patients wanting to choose larger implants. The cohesive silicone gel mimics the feel and movement of a natural breast better than a similar sized saline filled device. Although there is very little difference in the weight of silicone and saline filled devices of the same size, silicone gel implants subjectively feel less heavy and move less during exercise because the cohesive silicone gel filler moves around less vigorously than salt water.

  • You have limited breast tissue.

Statistically there is little difference in the incidence of visible rippling of the shell between saline and silicone gel implants. However, if your tissues are thin (allowing you to see your rib contours) then silicone gel filled implants are less likely to cause severe rippling and visual disappointments.

  • You are comfortable with the need for medical imaging to determine when your implants have broken.

Silicone gel implants can “silently rupture”. Fortunately there are no health consequences of this. Ruptured implants usually produce some change in the shape or feel of the breast over several months. These changes then trigger patients to see their Plastic Surgeon. When ruptured silicone gel implants need to be removed and replaced, the surgery can be more complicated than the surgery required to remove and replace a ruptured saline implant.

Dr. Mosher and his team of experienced nurses and care coordinators will help you to decide on the breast implant that matches your desired outcome, your preferences and your lifestyle. During consultation you can touch and try on implant samples of the implants recommended for you. We also offer VECTRA 3D simulations to help you to visualize the outcome from breast augmentation surgery.
