Question 11#

Which of the following is true of breast implants?

A. Saline implants have a lower capsular contracture rate than silicone
B. Silicone implants have a higher deflation rate than saline
C. Textured implants have a higher capsular contracture rate than smooth
D. Subglandular placement has a lower capsular contracture rate than submuscular
E. None of the above

Correct Answer is A

Comment:

Saline implants have a lower capsular contracture rate than silicone. Capsular contracture rates increase in the presence of foreign material and infection. As such, silicone leak increases rates of contracture (A is true), as does the presence of bacteria (subglandular) (D is false). Whilst silicone implants may rupture, they are unlikely to deflate. Quoted contracture rates are 58% for smooth silicone implants and 8% for textured.
