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.eninfo:eu-repo/semantics/closedAccessScalp DefectExposed CalvariumTrephinationPlatelet-rich Plasma (PRP)Article10.1016/j.jtv.2020.04.004293211215324170232-s2.0-85084483792Q2WOS:000555464900011Q1
