The manufacturers of breast implants clearly state that these devices aren’t intended to last a lifetime.Despite this, many patients can expect to have implants last their entire lifetime.Current studies suggest that implants deflate at a rate of one percent at one year and three percent at three years.Over time, this number can be expected to grow.Implants may deflate with no apparent cause or may deflate secondary to some type of trauma.When implants spontaneously deflate, the cause is usually implant fatigue.Over the course of time, implants simply wear out.Under these circumstances, the decision to replace implants is easy.If a patient is doing well and not having problems with breast implants, we see no reason to routinely replace implants, just because a set time period has passed.Although insurance doesn’t generally cover the cost of implant replacement, these devices do come with a warranty.In some cases, extended warranties can be purchased, as well.When implants deflate, the warranty usually covers the cost of replacement.
