Why do some patients have to wear a compression strap above the breasts? Braless timeframe?

Thank you for your question. Your surgeon may be wanting to influence the decent of the implants within the breasts over the first six months after surgery as it usually takes several months for the breasts to settle out. If the strap is uncomfortable I would revisit with your surgeon to see if there are other options. Otherwise, I would recommend following your surgeon's instructions and follow-up.

Your own surgeon will give you guidance on how long the strap is to be worn. Due to the action of the pectoral muscle, there is sometimes a tendency for implants to ride up so the strap holds them in place while the scar capsule forms. This is usually a week or so. If you want to maintain the shape of your breasts long term then wearing a bra most of the time is a good idea.

and I'm a believer if your implants are situated too high on your chest.  Implants settle and I believe the strap helps you achieve a more desired result that you have an active role in achieving.  And I would put my results up to anyone's as proof that it works.  My patients wear the strap 24-7 until they feel its 'good enough' then they can wear bras in nonfunctional ways or go braless (no lifting vectors) until perfect, at which point they start supporting their implants.  If this happens early, they will need to support their implants 24/7 to minimize the inevitable settling that occur with implants.
