Conditions
Brief summary
The purpose of this study is to evaluating whether autologous Concentrate Growth Factors(CGF) is safe and/or effective to accelerating skin regeneration and soft tissue expansion.
Interventions
CGF injection subdermally to expanded skin at the density of 0.02ml/cm2.
Saline will be injected into expanded skin

Exclusion criteria
* • Not fit for soft tissue expansion treatment; * Evidence of infection, ischemia, ulcer or other pathological changes within the targeting area which defined as not suitable for expansion; or history of delayed healing, radiational therapy; * Significant renal, cardiovascular, hepatic and psychiatric diseases; * Significant medical diseases or infection (including but not limited to the carrier of hepatitis B virus or HIV) * BMI \>30; * History of any hematological disease, including leukopenia , thrombocytopenia, or thrombocytosis; * History of allogenic bone marrow transplantation; * Long history of smoking; * Evidence of malignant diseases or unwillingness to participate.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To Measure the Change in Inflation Volume of the Silicone Expander From Baseline at 8 Weeks | baseline and 8 weeks post treatment | Record the inflation volume(ml) of each expander with the maintained inner pressure. The inflation volume was recorded according to the injection volume during expansion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To Measure the Texture of Expanded Flap With Canfield's Visia Scanner | baseline and 8 weeks post treatment | Evaluate skin texture with Canfield's Visia skin analysis imaging system and compare the characteristics including RBX red, RBX brown, pores, spots, et al. |
| Occurence of Major Adverse Events | Up to approximately 24 months after study start | Including expanded flap ischaemia, necrosis, fluidify, infection, and all other adverse events |
