Is Fat The Best Choice To Use In My Tracheostomy Scar Revision?
Q: Dr. Eppley, after enduring over twenty years of having an indented tracheostomy scar, I am finally getting it revised. I understand that up to 50% of the fat tissue that is used as a filler gets dissolved by the body while it is healing. Is it possible that one would need multiple visits over the years to keep adding filler injections or something of that nature? Also, if one were to avoid that route in favor of something “off the counter” which product would you recommend? Thanks in advance.
A:Most tracheostomy scars can be revised and the neck skin leveled by simply closing the deeper layers of the excised scar as it is closed. This brings in tissue from the side and fills the defect or area of missing tissue underneath the skin. Larger or more indented tracheostomy scars, however, do have a real subcutaneous tissue deficiency as a result of fat loss due to pressure atrophy caused by the indwelling tratcheostomy tube. When these are merely excised and closed, they will revert to some degree of inversion as the skin is essentially closed over an ‘open space’. This is why the placement of fat grafts can be so helpful in tracheostomy scar revisions. However, the choice of fat grafts is critical and should be a dermal-fat graft and not fat injections. These are small composite grafts that can be taken from many locations with a small resultant scar. There are no ‘off the shelf’ products, such as allogeneic dermal grafts, that are a good substitute for a supple dermal-fat graft.
