13 weeks out from lower face/neck lift. Have cording and hard lumps under chin - how do I fix this or will it go away? (photo)

I am imagining that you underwent a face and neck lift, as this can be a common problem with what is termed a "corset platysmaplasty."  It is still too early to judge the results, but often times while my patients are waiting for healing to occur, I will inject Botox into the platysmal muscles to temporarily relieve the "cords."  You will need to wait 2-3 more months in order to determine whether a revision will be necessary.

It is still early in the healing process to tell if a revision will be necessary. Please keep up the massages as suggested by your surgeon and continue to follow up with them.
