Breast implant surgery, a popular cosmetic procedure, aims to enhance breast size, shape, or fullness. However, like any surgical intervention, it has potential complications, and one of the more concerning issues is breast implant hardening, medically known as capsular contracture. This article will explore the causes, symptoms, diagnosis, and solutions for this condition.
What are breast implants
Breast implants are prosthetics used to alter the size, shape, or contour of a woman’s breasts. They come in two main types: saline – filled and silicone – gel – filled. Saline implants are filled with sterile salt water, while silicone implants are filled with a silicone gel that closely mimics the feel of natural breast tissue. These implants are placed either under the breast tissue (subglandular placement) or beneath the chest muscle (submuscular placement) during surgery.
Understanding capsular contracture (breast implant hardening)
Definition
Capsular contracture occurs when the scar tissue (capsule) that naturally forms around the breast implant tightens and compresses the implant. This tightening can cause the breast to feel hard, change shape, and sometimes become painful. The condition is graded on a scale from 1 to 4, with 1 being a normal – feeling breast and 4 being a severely hardened, painful breast.
Symptoms
Hardness: The most obvious symptom is a significant increase in the firmness of the breast. It may feel like a rock – hard mass rather than the softness expected with a properly functioning implant.
Shape distortion: The breast may change shape. It can become higher on the chest wall, more conical, or uneven compared to the other breast.
Pain: In more severe cases, the breast can become painful, especially when touched or during movement. The pain can range from mild discomfort to severe, sharp pain.
Causes of breast implant hardening
Bacterial contamination
Intra – operative contamination: During the surgical procedure, if bacteria enter the surgical site, they can colonize around the implant. Even a small amount of bacteria, such as Staphylococcus epidermidis, which is commonly found on the skin, can start an inflammatory response. This inflammation can lead to the formation of a thick, tight capsule around the implant.
Post – operative infection: Infections that occur after the surgery, although relatively rare, can also contribute to capsular contracture. If an infection is not treated promptly and effectively, the body’s immune response to the infection can cause the scar tissue around the implant to thicken and contract.
Implant type and texture
Silicone vs. saline: Some studies suggest that silicone – gel implants may have a slightly higher risk of capsular contracture compared to saline implants. However, the difference is not significant, and both types can be affected.
Smooth – textured vs. textured implants: Textured implants were initially thought to reduce the risk of capsular contracture because the rough surface was supposed to prevent the capsule from forming a smooth, tight seal around the implant. However, in some cases, textured implants have been associated with a different type of complication, anaplastic large – cell lymphoma (ALCL), and the relationship between implant texture and capsular contracture is still being studied.
Surgical technique
Implant placement: The location where the implant is placed can impact the development of capsular contracture. Subglandular placement (above the muscle) may have a higher risk compared to submuscular placement (under the muscle). The muscle can provide some natural cushioning and may reduce the body’s inflammatory response to the implant.
Cavity creation: If the surgical cavity created for the implant is too small, it can put pressure on the implant, leading to an increased risk of capsular contracture. Additionally, if the surgeon does not achieve proper hemostasis (control of bleeding) during the surgery, the presence of blood around the implant can trigger an inflammatory response.
Patient – related factors
Immune response: Each person’s immune system reacts differently to the presence of a foreign object like a breast implant. Some individuals may have a more aggressive immune response, leading to the over – production of scar tissue.
Smoking: Smokers are at a higher risk of capsular contracture. Nicotine in cigarettes restricts blood vessels, reducing blood flow to the surgical area. This can impair the body’s ability to heal properly and increase the risk of inflammation and scar tissue formation.
Previous breast surgery: Women who have had previous breast surgeries, such as breast reduction or biopsy, may have a different tissue structure in the breast. This altered tissue can affect how the body responds to the implant and may increase the risk of capsular contracture.
Diagnosis of breast implant hardening
Physical examination
The first step in diagnosing capsular contracture is a physical examination by a qualified plastic surgeon. The surgeon will feel the breast to assess its firmness, check for any changes in shape, and determine if there is any pain or tenderness. They will also compare the two breasts to look for symmetry and any differences in texture or firmness.
Imaging tests
Mammogram: A mammogram can provide some information about the implant and the surrounding breast tissue. However, it may not be the most accurate test for diagnosing capsular contracture as the dense tissue of the implant can sometimes obscure the view of the capsule.
Ultrasound: Ultrasound is a more commonly used imaging test for evaluating breast implants. It can show the structure of the implant, the thickness of the capsule around it, and any signs of fluid accumulation or rupture.
MRI (Magnetic Resonance Imaging): MRI is the most accurate imaging modality for assessing breast implants. It can clearly show the implant, the capsule, and any potential complications, including capsular contracture. However, it is more expensive and may not be necessary in all cases.
Treatment options for breast implant hardening
Conservative treatments
Massage: In the early stages of capsular contracture, breast massage may be recommended. Gentle, regular massage can sometimes help to stretch the capsule and prevent it from tightening further. The patient is usually taught specific massage techniques to perform at home.
Medication: Anti – inflammatory medications may be prescribed to reduce the inflammation associated with capsular contracture. These medications can help to relieve pain and may slow down the progression of the condition. In some cases, corticosteroid injections directly into the capsule may be used, but this approach has some risks, such as the potential for infection and implant rupture.
Surgical treatments
Capsulotomy: This is a surgical procedure where the surgeon makes an incision in the capsule around the implant to release the tightness. It is a relatively simple procedure but may have a higher recurrence rate of capsular contracture.
Capsulectomy: In a capsulectomy, the surgeon removes the entire capsule around the implant. This is a more comprehensive approach and is often recommended for more severe cases of capsular contracture. After the capsulectomy, the implant may be re – positioned, replaced, or removed, depending on the patient’s preference and the condition of the implant.
Implant replacement: If the implant is old, damaged, or if the patient desires a different type of implant, implant replacement can be done during the surgery to correct capsular contracture. The new implant may be placed in a different location or may be a different type (e.g., switching from silicone to saline or vice versa).
Prevention of breast implant hardening
Sterile surgical technique
Surgeons must follow strict sterile procedures during breast implant surgery. This includes thorough skin preparation, the use of sterile surgical instruments, and proper draping to minimize the risk of bacterial contamination.
Appropriate implant selection
Based on the patient’s anatomy, lifestyle, and goals, the surgeon should recommend the most suitable type of implant. Considerations should include implant size, type (silicone or saline), and texture. In some cases, a combination of factors may be weighed to reduce the risk of complications.
Post – operative care
Antibiotic prophylaxis: Short – term use of antibiotics after the surgery can help prevent post – operative infections. The type and duration of antibiotic use are determined by the surgeon based on the patient’s individual risk factors.
Follow – up appointments: Regular follow – up appointments with the plastic surgeon are crucial. The surgeon can monitor the healing process, check for any signs of complications, and provide early intervention if necessary.
Conclusion
Breast implant hardening, or capsular contracture, is a potential complication of breast implant surgery. Understanding its causes, from bacterial contamination to patient – related factors, is essential for both patients and surgeons. Early diagnosis through physical examination and imaging tests allows for timely treatment, whether it be conservative measures like massage and medication or surgical interventions such as capsulectomy. By taking preventive measures, such as using sterile surgical techniques and proper post – operative care, the risk of capsular contracture can be significantly reduced, ensuring better outcomes for patients undergoing breast implant surgery.
