Saline breast implants are a popular choice for women undergoing breast augmentation surgery. These implants, filled with sterile saltwater, offer a natural feel and are considered a safer option compared to silicone implants, in part due to their reduced risk of complications like leakage. However, one common concern among women who choose saline implants is the phenomenon of implant hardening, often referred to as “capsular contracture.” This condition can cause the breast implant to become firm or hard, which can be uncomfortable or aesthetically undesirable. Understanding why saline implants get hard is essential for those considering breast augmentation or for those experiencing this issue post-surgery.
Understanding Saline Breast Implants
Before diving into the reasons why saline implants can harden, it’s important to understand how these implants function. Saline implants are filled with a sterile saltwater solution after being placed inside the breast. They are typically inserted in a deflated state and then inflated once positioned properly. The primary benefit of saline implants is their ability to be adjusted for size and firmness during the procedure, which allows for more precise customization compared to silicone implants.
Saline implants, unlike silicone, are less likely to rupture or leak in a way that poses a health risk. If the implant ruptures, the saline solution is harmlessly absorbed by the body. However, despite their many benefits, saline implants can sometimes experience complications, the most common being capsular contracture.
What is Capsular Contracture?
Capsular contracture is a condition that causes the natural scar tissue that forms around an implant to tighten and harden. The body’s immune response to a foreign object, like a breast implant, leads to the formation of this fibrous capsule. While this process is normal, in some cases, the capsule can tighten excessively, leading to hardening of the implant, discomfort, and changes in breast shape.
In the case of saline implants, the effects of capsular contracture are noticeable because the implants are filled with water, which has a more noticeable texture than the silicone gel used in other types of implants. As the scar tissue contracts around the saline implant, the implant itself can feel firm or hard to the touch.
Factors That Contribute to Saline Implant Hardening
Several factors contribute to why saline implants may harden or become firm. These can range from the body’s natural response to the implant to external influences and the technique used during the implant procedure.
1. Body’s Natural Healing Response
When a breast implant is placed in the body, the body begins to form a capsule of scar tissue around it. This is a natural process aimed at walling off the implant and protecting the surrounding tissue. However, for reasons that are not fully understood, this process can sometimes go awry. In certain cases, the scar tissue becomes thickened and tight, which causes the implant to feel firm or hard. The severity of capsular contracture can vary from mild firmness to significant tightness that distorts the breast’s shape and can be painful.
2. Infection or Inflammation
While rare, infection or inflammation following breast augmentation surgery can lead to the development of capsular contracture. Infections can trigger an exaggerated immune response, leading to the formation of excessive scar tissue around the implant. Even a mild infection or irritation can increase the risk of this complication. Any inflammatory process, such as implant leakage or a seroma (a pocket of fluid), can also contribute to the development of hardening around the implant.
3. Implant Placement
The position where the saline implant is placed can influence the likelihood of capsular contracture. Implants can be placed either under the chest muscle (submuscular) or above it (subglandular). Studies suggest that implants placed under the muscle tend to have a lower risk of developing capsular contracture compared to those placed above the muscle. This is because the muscle helps to “massage” the implant, potentially reducing the chance of excessive scar tissue formation. Additionally, implant placement can impact the final shape of the breast and its long-term firmness, making surgical technique an important factor.
4. Implant Texture
Saline implants are available in both smooth and textured varieties. Textured implants, designed to help prevent rotation and improve stability, have a rough surface that may reduce the risk of capsular contracture. On the other hand, smooth implants, while easier to insert and position, are more prone to shifting and may have a higher incidence of hardening over time. Some studies suggest that textured saline implants, though they may carry a higher risk of certain complications, are less likely to become hard than their smooth counterparts.
5. Overfilling or Underfilling
The volume of saline used to fill the implant can also affect the firmness of the implant. Implants that are overfilled with saline may become firmer, as the extra fluid places more pressure on the implant shell, leading to increased tension in the surrounding tissue. On the other hand, underfilled saline implants can also lead to a higher risk of folding or wrinkling, which may create areas of uneven pressure around the implant, potentially leading to complications like capsular contracture.
6. Smoking
Smoking is a known risk factor that can impair the healing process following breast augmentation surgery. Nicotine restricts blood flow to tissues and can hinder the body’s ability to heal, increasing the chances of complications like capsular contracture. Smokers are more likely to experience hardening of their implants, as the body’s response to the implant may be altered by the reduced circulation caused by smoking.
7. Genetic Predisposition
Some individuals may be more prone to developing capsular contracture due to their genetic makeup. Research has shown that women with certain genetic traits may be more susceptible to an excessive scar tissue response. While this is not something that can be changed, women considering breast implants should discuss their family history and personal health with their surgeon to better understand their risks.
How to Prevent or Manage Capsular Contracture
While there is no guaranteed method to prevent capsular contracture from occurring, several strategies may reduce the risk or help manage the condition if it does develop.
1. Careful Surgical Technique
Choosing a skilled and experienced surgeon is one of the most important factors in reducing the risk of capsular contracture. Surgeons can minimize trauma during the procedure and ensure the implants are positioned optimally. Additionally, proper implant selection, such as opting for textured implants or submuscular placement, can help reduce the risk of complications.
2. Post-Operative Care
Following surgery, it’s crucial to follow all post-operative instructions, including recommendations for massaging the breasts, avoiding smoking, and attending follow-up appointments. Some surgeons recommend gentle massage of the breasts to prevent tight scar tissue from forming and encourage the capsule to remain soft.
3. Treatment Options
If capsular contracture does occur, various treatments are available. These can range from non-invasive measures, such as massage or corticosteroid injections, to more invasive solutions like capsulectomy (removal of the scar tissue) or implant replacement.
Conclusion
Saline implants can harden for several reasons, with capsular contracture being the primary cause. While the development of hard implants is a common complication, it is not inevitable. Understanding the factors that contribute to capsular contracture, including surgical techniques, implant placement, and post-operative care, can help reduce the risk. Women who experience hardening after breast augmentation should consult with their surgeon to explore the best options for treatment and management.
