Is it safe to wait 2 months to replace ruptured implant? Abrading breast tissue/developing scar tissue that affects the pocket?

Most women like to have a deflation dealt with as soon as possible.  There is no harm in waiting however.  The pocket may shrink down around the old implant so the space may need to be recreated, but that's not a big deal.  If you had no problem with smooth implants, stick with the smooth ones. Also, saline implants usually have a lifetime warrantee. Make sure you check into that.

If you did not have a capsular contracture, are not interested in changing your size, and you dont need a lift, replacing the implant in the same pocket sounds like an easy way to go.  There is no rush to change the implants, you can continue living with a deflated implant and you may concider an office procedure to deflate the other implant so that you can have symmetry until you are ready for surgery to replace both implants.

You can wait for a few weeks to a few months after an implant ruptures.  The tissue will contract somewhat but this should not be too much of an issue in an experienced surgeon's hands.  Replacing the implant with a similar implant is possible, however depending on how the native breast tissue looks, and how much laxity there is, a possible lift may be necessary.  A consultation is necessary for a proper surgical plan.
