Breast implants are sophisticated medical devices designed to enhance the size and shape of the breast mound, but they are not considered lifetime devices. While modern implants are engineered for significant durability, they will eventually require removal or replacement. The need for a second surgery is a reality for anyone undergoing this procedure, whether due to a complication or simply the passage of time. Understanding the expected lifespan and the factors that influence it is an important part of the decision-making process for breast augmentation.
The Expected Lifespan
Breast implants do not come with a set expiration date, but they are generally expected to have a physical lifespan of ten to twenty years. Implants are not considered “lifetime devices,” meaning the risk of rupture or complication increases the longer they remain in the body. This range represents the typical period before mechanical wear or biological complications necessitate intervention.
Some manufacturers offer a ten-year warranty against rupture, but this is a guarantee against specific failure, not a mandatory removal date. Many implants remain intact and functional well beyond the ten-year mark, sometimes lasting 25 years or more.
Approximately 20% of patients will undergo a revision surgery, which is a removal or replacement procedure, within eight to ten years of the initial placement. Replacement is often an elective choice based on changing aesthetic goals or natural body aging. The decision to replace is typically made when a complication arises or when the patient desires a cosmetic change. The likelihood of complications increases by about one percent each year after the first decade the implants are in place.
Factors Influencing Durability and Wear
The actual longevity of a breast implant is highly variable and depends on material science and patient-specific factors. Saline-filled implants often have a slightly shorter average lifespan, sometimes closer to ten to fifteen years, compared to cohesive silicone gel implants. The outer shell of any implant is subject to wear and tear over time, which can lead to a breach in its integrity.
Modern silicone implants utilize a highly cohesive, or “gummy bear,” gel that is designed to maintain its shape even if the outer shell tears. This newer gel technology generally contributes to greater durability than older generations of implants. The surgical placement also plays a role, with implants placed partially beneath the chest muscle (submuscular) potentially experiencing less external pressure and movement than those placed only under the glandular tissue (subglandular).
Patient lifestyle factors also contribute to the rate of wear on the implant. Significant weight fluctuations, for example, can stretch the overlying breast tissue and skin, which may affect the implant’s position and appearance. Excessive trauma to the chest area or high-impact physical activities can also accelerate the wear-and-tear process on the shell. Smoking is another factor that negatively impacts circulation and healing, potentially increasing the risk of complications that shorten the implant’s functional life.
Recognizing Implant Failure and Rupture
Implant failure typically presents in two distinct ways, depending on the filler material. A rupture of a saline implant is usually immediately noticeable because the sterile saltwater solution is rapidly absorbed by the body. This results in a sudden, visible deflation of the breast, which makes the implant’s edges or ripples highly visible. While the deflation is not a medical emergency, the implant must be removed and replaced to restore breast shape.
Silicone implant rupture is more difficult to detect because the cohesive gel often remains contained within the scar tissue capsule that naturally forms around the implant. This condition is frequently referred to as a “silent rupture” because it may not cause immediate symptoms or a change in breast contour. However, leaked silicone can sometimes irritate the surrounding tissue, leading to symptomatic problems.
Common physical signs that may indicate failure or a related complication include breast pain, thickening, or a change in contour or shape. The most frequent long-term complication is capsular contracture, where the surrounding scar tissue hardens and tightens around the implant. This causes the breast to feel firm, painful, or distorted.
For silicone implants, the gold standard for detecting a silent rupture is magnetic resonance imaging (MRI). The FDA often recommends MRI screening five to six years after placement and then every two to three years thereafter.
Replacement and Removal Procedures
When an implant reaches the end of its functional life or a complication occurs, a secondary surgery is necessary, which can range from elective replacement to revision surgery. Elective replacement involves exchanging the old implants for new ones before any failure occurs, often to update the size, shape, or type. Revision surgery is performed specifically to address a complication, such as a rupture or severe capsular contracture.
The surgical removal of the implant is called explantation. In almost all cases, explantation is accompanied by a capsulectomy, which is the removal of the scar tissue capsule that has formed around the device. A total capsulectomy removes the entire capsule, while an en bloc capsulectomy removes the implant and the surrounding capsule in a single, intact unit.
Removing the capsule is especially important in cases of silicone rupture, as the en bloc technique prevents any leaked gel from spreading into the surrounding tissue. After explantation, the patient has several options. They may choose to replace the implant, opt for a breast lift to reshape the remaining tissue, or use fat grafting to restore volume and contour.
