Treatment of scalp defects with a combination of trephination and platelet-rich plasma

In cases of complete scalp loss where the calvarium is exposed and reconstruction cannot be achieved using replantation, or local or far flaps, using trephination to create holes to the depth of the spongeous layer followed by grafting once granulation has covered all defects is an important reconstruction alternative. However, growth of the granulation after trephination and waiting for the entire defect to be covered is a slow process. Since the introduction of platelet-rich plasma (PRP), several researchers have investigated the efficacy of different bone healing and grafting procedures. We present a case with full-thickness partial scalp defect in which we support the development of granulation through holes drilled to the spongeous layer by trephination with PRP.
