What is a Capsular Contracture?
A capsule of natural scar tissue forms around all implants placed inside the body – whether a breast implant or a knee implant. In most cases, this capsule remains soft and does not cause issues. However, in some instances, the capsule tightens and hardens, leading to capsular contracture. The severity of capsular contracture is graded using the Baker scale:
- Baker Grade 1: The breast is soft and feels normal
- Baker Grade 2: The breast is slightly firm but looks normal
- Baker Grade 3: The breast is firm and looks abnormal
- Baker Grade 4: The breast is hard, painful, and looks abnormal
Assuming the implant was properly placed, Baker Grade 3 to 4 capsular contraction is a common cause of the implant “riding high” or not dropping.
Why certain people have a propensity for developing capsular contraction remains a topic of research. However, capsular contraction has been associated with:
- Implant Rupture: Leakage from a ruptured implant can irritate surrounding tissues, leading to inflammation and tightening of the capsule around the implant.
- Autoimmune Responses: Some individuals may have a strong immune reaction to the implant material, triggering excessive capsule formation.
- Innate Scar Response: Certain people naturally form thick scar tissue, such as keloids. Individuals with a history of keloid formation may be at higher risk of capsular contracture.
- Biofilm or Infection: The presence of bacteria or a biofilm on the implant surface can lead to chronic inflammation, which contributes to capsular tightening.
- Hematoma or Seroma: Blood or fluid accumulation around the implant can irritate tissues and increase the risk of contracture.
- Powdered Glove Dust: Residual powder from surgical gloves can act as a foreign substance, triggering inflammation.
- Hormonal Changes: Significant hormonal fluctuations, such as those during pregnancy, may influence the capsule’s development and thickness.
