I would recommend that you follow the advice of the doctor who will be performing your surgery and who is going to be taking care of you in the postoperative period. There is no one that is in a better position to guide you in your recovery other than the Plastic Surgeon who will be performing your operation. Now as far as my own practice is concerned, yes, I do advise my patients who have breast augmentation surgery to wear a surgical bra. This is simply for the reason that there is a benefit in having some support at least in the early period during the recovery from breast augmentation surgery. There is very little hard data in the literature supporting the use of a sports bra versus no sports bra at all. There is actually only one study that I can recall that is about 15 years old that reported that there was no improvement in the incidence of deep bruising or bleeding following breast augmentation with a sports bra compared to no sports bra at all. Therefore, you will get different opinions on this subject. You will have surgeons that categorically advise their patients to wear a sports bra and others who recommend that no bra be worn. I think a lot of it also has to do with exactly what operation is being done and what kind of implant device is being used for the augmentation. Certainly, there is a difference in the behavior of saline versus silicone implants in the way that they move in the body. There is also a significant difference between the recovery and the movement of textured implants versus smooth implants. Of course, we are not even talking about more complicated operations such as breast augmentation in combination with a breast lift. So, there are many different possibilities depending on the exact operation that is done and the exact device that is being used. Essentially, it boils down to the experience of your surgeon and what he/she believes will be the best way for you to recover following your operation. So, I would take the advice of your Plastic Surgeon and I am sure your results will be very, very good. Best of luck to you!
