Application of microfat injection in the treatment of facial hypertrophic scar / 中华整形外科杂志

ABSTRACT

Objective@#To investigate the clinical outcome of microfat injection on facial hypertrophic scar treatment.@*Methods@#A total of 22 patients had facial hypertrophic scar were treated with microfat injection. The microfat was injected into the scar three times for each case, with an interval of 2 months. The severity of scar was evaluated preoperatively and 1-month postoperatively, using modified Vancouver scar score, to evaluate the efficacy.@*Results@#Postoperative infection occurred in 1 case, and no further microfat injection was performed on him/her. All the other 21 cases have relieved cicatricial hyperemia, with the scar softening and flattening. The symptom of itching and pain were alleviated as well. The overall effective rate was 95.45%. The score of modified Vancouver scar scale was reduced from 12.82±2.15 preoperatively, to 7.05±1.76 6 months after the treatment (P<0.05).@*Conclusions@#The microfat injection can effectively improve the color and texture of the facial hypertrophic scar, and reduce the symptoms of itching and pain. It is a new choice for the treatment for hypertrophic scar.
