NSM with immediate recon some necrosis one week post surg

just had 1 week post op and one side perfect. Other has necrosis on incision line (not big prob but will be operated next week to remove) but more concerning larger patch of skin not healing. Told to give it a week to hope it starts healing or else will need to graft skin/remove implant. Any experience? Anything I can do to help healing? Thank yo
