[Reconstruction of the frontoorbital frame using split-thickness calvarial bone grafts]

There are many autogenous and allogenous grafts as well as alloplastic materials available for the reconstruction of craniofacial bony frame. We review our techniques and describe the advantages of using calvarial bone, especially split-thickness grafts for bone reconstruction in this area.

Between 1996 and 2003 the orbitocranial bony frames of 15 patients were reconstructed using split calvarial bone grafts at the ENT-Department of the Hospital Fulda gAG. In 12 patients the anterior frontal sinus wall or the entire Os frontale were affected. In 1 patient each the lateral wall, roof and floor of the orbit had to be reconstructed. The causes of the bone defects were trauma (n = 6), recurrent frontal sinusitis partly with osteomyelitis (n = 4), benigne tumors (n = 2) and malignancies (n = 3). Twelve patients have had multiple previous operations. In 3 patients the bone reconstruction was performed in the same operation as the tumor removal. Within the follow-up period between 2 and 8 years the split calvarial bone grafts remained stable in size and shape. Graft rejection, osteomyelitis or bone resorption did not occur. Furthermore, we have not experienced significant complications in harvesting cranial bone and have not seen major donor site morbidity.

Our results demonstrate that split-thickness calvarial bone is an excellent graft not only for facial and forehead contouring but also for orbital and complex craniofacial reconstruction.
