Fat Grafting in Skin-grafted Deep Burn Scars

Not Applicable
Completed
Conditions
Burn Scar
Interventions
Procedure: placebo injection
Procedure: lipofilling/ fat grafting
Registration Number
NCT03627650
Lead Sponsor
University Hospital, Ghent
Brief Summary

fat grafting in human skin-grafted immature burn scars histological, clinical and photographic follow-up

Detailed Description

Objective: A randomised clinical trial was performed to determine the effect of autologous fat grafting on scar formation in early skin-grafted deep burn wounds.

Methods: Included patients received split-thickness skin grafting procedures for deep burn wounds less than 3 months ago. A homogenous scar area in each patient was divided into two equal parts. One part was treated with transcutaneous sharp needle autologous fat grafting, the adjacent part with transcutaneous saline injection as control. Results were evaluated by clinical assessment with scar scale questionnaires, histological examination, and objective scar assessment with Cutometer, Mexameter, Tewameter and Corneometer.

Primary Outcome Measures
NameTimeMethod
improvement of scar quality by physiological testing with cutometer6 months, 1 year

measures elasticity of the scar; micrometer; higher values better outcome

Improvement of scar quality by subjective evaluation with numerical Vancouver Scar Scale1 year

numerical score 0 to 13; ranges vascularity, height/thickness, pliability, and pigmentation

Improvement of scar quality by histological assessment6 months

histology of scar tissue, scoring by 2 independent blinded anatomopathologists, (numerical scoring of fibroblast activity, collagen and elastin organisation, vascularity) scoring range min 1(close to normal tissue) - 3 (scar characteristics)

physiological testing of scar tissue by corneometer6 months, 1 year

measures hydration of the epidermis; corneometer units, higher values better outcome

Improvement of scar quality by subjective evaluation with numerical POSAS (Patient and Observer Scar Assessment Scale) Scale1 year

numerical score 5 to 50: VSS plus surface area; patient assessments of pain, itching, color, stiffness, thickness, relief

improvement of scar quality by physiological testing with TEWA-meter (Trans Epidermal Water Loss-meter)6 months, 1 year

measures transepidermal water loss; g/m2/h; higher values worse outcome
