Reconstruction of a Cranial Bone Defect With Hydroxyapatite and Free Flap Transfer

Abstract

The authors report a successful reconstruction of an extensive frontotemporal bone defect after craniotomy, which was complicated with infection and necessitated removal of frontal and temporal bones. The large frontotemporal bone defect was reconstructed using prefabricated hydroxyapatite blocks in combination with the free vastus lateralis muscle flap. The patient's functional and cosmetic restoration has been maintained for 10 months' follow-up.
