NCT03872544

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in drainage, erythema, oedema, and pain; and the presence of intact tissues associated with the wound

    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 Outcomes (4)

  • Change in 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

    Evaluated through study completion, an average of 2 years.

  • Ratio for tissue type in the wound site

    Evaluated through study completion, an average of 2 years.

  • Ratio of immune cell populations in the wound site

    Evaluated through study completion, an average of 2 years.

Sampling MethodNon-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).

You may qualify if:

  • Presence 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
  • Presence of wound contracture, breakdown of overlying tissue, or challenging anatomical deformities
  • 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

You may not qualify if:

  • 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
  • Does not speak, read, or understand English
  • Unwilling to freely give consent
  • Is unable or does not have a legal representative to give consent

Biospecimen

Retention: SAMPLES WITHOUT DNA

Prepared and stained slides made from the material obtained during biopsies will be retained for use in the clinical care of the patient and research. Other material stored in formalin from biopsy specimens obtained will be banked for future use in immunohistochemistry studies to further define free DFA physiology. Additional IRB approval to use any the material from biopsy specimens for any future studies will be obtained. The specimens will not be shared with outside researchers.
