Can a breast implant capsule rupture be repaired? Or will it heal on its own?

It depends upon the extent of the tear- an MRI should help. It may or may not heal with conservative measures such as tape, bra. If severe, it may require revision, possible biologic mesh.Close follow up with your plastic surgeon is recommended.

A capsule rupture in itself is not a problem, unless when the capsule heals the implant heels in a new position.  If that is the case, a corrective surgery will be needed.  You are taking the right first step with an MRI.Best of luck!

Sorry to hear that you are going through this.  The MRI needs to be done to determine what is really going on.  If it was capsule superiorly at the top of the implant it would likely just heal.  At the base of the implant where you are describing where you need a bra for support 24/7 this area isn't likely going to heal on its own since it is under constant pressure from the implant weight.  A bra 24/7 "may" allow it to heal and so should be tried first but chances are you need something more invasive like Galaflex or Alloderm to create an "internal bra" rather than the one you are wearing externally.  Good luck! 

If it was very recent, you may be able to get away with some sort of support in the area while the capsule heals. If not you might need revision surgery.

     First, it is important to have the MRI results and any additional studies deemed appropriate to be sure that the issue is a tear in the tissue capsule around the implant and not an issue with the implant.  If the tissue capsule is indeed damaged, it can be repaired (capsulorrhaphy).  This procedure often utilizes a material that acts like an internal bra (acellular dermal matrix such as Alloderm).  Discuss your options after all the tests are complete and good luckj
