Facelift wound will not heal. What can I do? (Photo)

That should have healed in by 7 months. There could be a deep stitch preventing it from closing. I think you need a more aggressive approach is indicated with mire aggressive debridement to remove any dead tissue or foreign substance like a stitch.

After 8 months I'd be concerned there is something else going on prohibiting wound healing. Other things to consider are retained foreign body (stitch), skin cancer, chronic low grade infection and salivary fistula/drainage. Biopsy, wound cultures or evaluation of any drainage for saliva proteins can be performed to investigate further. Additionally, if the wound is scabbing and crusting it is possible you may not be caring for the wound appropriately. Often, we use antibiotic ointment and a semi-occlusive dressing (such as Adaptec) to keep the wound moist and allow for the serous drainage to escape. We usually don't want to see crusting as the scab will prevent the skin from healing underneath.
