Revisional breast surgery implies a repeat operation
The surgical use of the word “revision” implies more than repeat; it means going back to the site of a previous operation and performing another one, similar perhaps but not necessarily the same. The reasons are multiple – there may have been an anticipated or unanticipated complication, the patient may not be satisfied with a cosmetic result although there is no other issue, the procedure may need to be repeated because the implant has become worn or damaged (not only breasts, applies to pacemakers and eye lens implants).
In terms of revision of breast surgery, the patient may be dissatisfied with a poor result, or perfectly satisfied but now wants the breasts made larger or smaller; something may have happened to the prosthesis and it needs to be replaced; the prosthesis may not have changed but the patient wants a different type (switch from saline to gel); there may have been post-augmentation changes due to pregnancy, weight gain or loss, or advancing age.
