Short Term Status of Free Dermal Fat Autografts for Complex Craniofacial Wounds (FTFDT3)

June 14, 2022 updated by: Dufresne, Craig, MD, PC

Fat to the Future, Dermal Time 3: Short and Medium Term Clinical and Histological Status of Free Dermal Fat Autograft Recipient Sites: Observational Study of a Prospective Cohort Treated for Complex Craniofacial Wounds

This study will evaluate the use of free autologous dermal fat grafting (also called free dermal fat autografting) to treat complex craniofacial wounds that have failed standard treatment and to understand how well these grafts work to repair wounds long term. Patients who have undergone free autologous dermal fat grafting to treat complex craniofacial wounds less than 1 week ago will have photographs and small biopsies taken of the area that was grafted. Patients will be followed for 2 years to monitor the area that was grafted.

Detailed Description

A complex craniofacial wound is a wound on the head or face that will not heal, despite efforts to heal the wound with standard treatments, such as antibiotics and surgery to clean the wound. Currently, there are no good treatment options for these types of complex craniofacial wounds. This study will evaluate what happens when free dermal fat autografting is used to help treat complex craniofacial wounds by evaluating the area where the graft was placed to better understand how these types of grafts function. Free dermal fat autografting is the process of taking fat from under the outer layer of skin and moving it to another part of the body of the same individual. Although free dermal fat autografts have been used for many decades in plastic and reconstructive surgery to help a variety of patients suffering from different problems, only one study has used them to help heal complex craniofacial wounds. This use of free dermal fat autografting is not considered to be experimental or an investigational product by the US Food and Drug Administration (FDA). Still, the use of free dermal fat autografting has not been formally evaluated to understand how these types of grafts help patients with complex craniofacial wounds.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

Potential patients are any consecutive patients not part of a retrospective cohort who undergo free autologous dermal fat grafting for one or more complex craniofacial wounds, carried out by a single sub-speciality trained plastic surgeon (Study Principal Investigator).

Description

Inclusion Criteria:

  • Patient has had two or more failed reconstructive attempts or has failed two or more attempts to treat local infection
  • Speak, read, and understand English
  • Willing to freely give consent
  • Is able or has a legal representative to give consent

Exclusion Criteria:

  • Absence of a complex craniofacial wound, defined by failure of initial reconstructive and antibiotic treatment and the presence of chronic infection, exposed hardware, irradiated local tissue, or soft tissue volume loss
  • Absence of wound contracture, breakdown of overlying tissue, or challenging aesthetic deformities
  • Patient has not had two or more failed reconstructive attempts or has not failed two or more attempts to treat local infection

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in drainage, erythema, oedema, and pain; and the presence of intact tissues associated with the wound
Time Frame: Evaluated through study completion, an average of 2 years.
Visually appraised evidence of drainage, erythema, oedema, and pain; and the presence of intact tissues associated with the wound
Evaluated through study completion, an average of 2 years.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in volume and contour of the defect associated with the wound
Time Frame: Evaluated through study completion, an average of 2 years.
Visually appraised volume and contour of the defect associated with the wound
Evaluated through study completion, an average of 2 years.
Concentration of adipocytes, mast cells, macrophages, and dermal lymphocytes in the wound site
Time Frame: Evaluated through study completion, an average of 2 years.
