Tethering after breast explant en bloc. What other option do I have other than surgical? (photo)

Thank you for sharing your question and photograph.  You did not mention how long it has been since your en bloc but I would first allow a full 6 months to pass while performing aggressive scar massage and tissue massage techniques.  Based on severity of your tethering and scar indentations you will most likely require additional surgical intervention but be fully healed before doing so. 

Depending how far out from surgery you are, massage of the tissues may help.  If you have already fully healed then surgery will provide you the best correction.  Depending on the complexity you may be able to have the procedure under local anesthesia, but an exam would be necessary in order to determine the best approach.
