The test site of expander implantation was divided into three groups: intradermal injection of CGF group, normal saline group and blank group. The same amount of expansion was performed every 1\u20132\u2009weeks, and CGF or normal saline was injected into the dermis every 4\u2009weeks, a total of three times.
