Case Study – Tracheostomy Scar Revision with Dermal-Fat Graft

 

Background: A tracheostomy is a life-saving airway procedure. Done from infancy to seniors it is the introduction of a breathing tube through the midline neck skin into airway to bypass whatever obstruction lies above it. The breathing may be left in a matter of days dependent on the medical condition it is treating. When it is removed, the open neck wound is left to heal in on its own.

While most tracheostomy scars will heal, the process of secondary intentional healing often leaves a wide scar which may have some degree of depression. The longer the breathing tube was left in place usually make for more of a depressed tracheostomy scar. This is due to the tissue loss between the skin and the trachea which has occurred due to compression and fat atrophy.

In some depressed tracheostomy scars, a very visible retraction of the neck skin is seen when swallowing. This is due to tethering of the overlying scarred and shortened neck tissues to the trachea. The trachea is moved upward due to contraction of the muscles at the base of the tongue. The skin edges of the tracheostomy scar can be seen to pull upward and into the depressed scar area as swallowing occurs.

Tracheostomy Neck ScarTracheostomy Neck Scar RetractionCase Study: This 24 year-old female had a depressed midline neck scar from a tracheostomy performed when she was an infant. She did not remember why she had the tracheostomy placed or for how long it was in place. When she swallowed there was a dramatic upward retraction of the tracheostomy scar.

Dermal Fat Graft to Tracheostomy Scar Dr Barry Eppley IndianapolisUnder local anesthesia, the tracheostomy scar was excised and the deeper tissues released from the trachea. A small dermal-fat graft was harvested from the lower abdomen and inserted dermal side down into the defect. It was sutured into placed and the skin closed over it.

While excising the neck scar and closing the skin over it seems like it would be a good scar treatment, it often is not. The very depressed trach scar is really missing subcutaneous tissue. An autologous dermal-fat graft is needed to replace what had been lost previously to both eliminate the depression and reduce the degree of tracheal retraction that is seen.

Highlights:

1) Depressed tracheostomy scars that retract on swallowing have a severe shortage of tissue.

2) To eliminate the soft tissue depression and decrease the visible tracheostomy scar retraction, a tissue graft is needed to fill in the space after scar excision and release.

3) The best tissue graft for any depressed scar is a dermal-fat graft.
