Are unsatisfactory results common after breast augmentation surgery with silicone breast implants?

A patient may be displeased for any number of reasons. The incidence of reoperation for a unsatisfactory result was shown to be roughly 2% of the 15-24% overall re-operative incidence in primary breast augmentation. So, the incidence of reoperations for unsatisfactory results seems to be well below 1%. This is not to say that all patients who are dissatisfied, are dissatisfied to the point of wanting another operation to address the problem, but the answer to whether or not unsatisfactory results are common is no.
