Pasteurized Tumoral Autograft for the Reconstruction of Monostotic Fibrous Dysplasia in Frontal Bone

Lee, Eui Tai

Abstract

PURPOSE
For the best possible aesthetic reconstruction after craniofacial bone tumor resection, pasteurization has been adopted to devitalize neoplastic cells while maintaining osteoinductive properties and mechanical strength. This case report aims to demonstrate a long-term follow-up result of a monostotic fibrous dysplasia in frontal bone which was reconstructed by pasteurized tumoral autograft in situ.
METHODS
A 14-year-old girl presented with a hard, nontender, slowly growing mass of 6-year duration on her left supraorbital area. CT showed 5 x 4 x 3 cm sized well defined bony mass confined to frontal bone with heterogeneous density. Tumor was excised completely through bicoronal approach and reimplanted to its original site after pasteurization at 60feminineC for 30 minutes. The pathologic examination confirmed fibrous dysplasia.
RESULTS
She revisited our clinic 5 years later after suffering some assault on her face. On CT examination, pasteurized tumoral autograft was incorporated to host bone except the fractured upper orbital rim without any evidence of recurrence. She has been satisfied with the result.
CONCLUSION
Pasteurization offers a simple, reliable, cosmetic, economic, and durable reconstruction method for craniofacial skeletal tumor. It has advantages of both biologic incorporation ability and mechanical strength without risk of recurrence. So, it should be considered as one of the primary options in benign as well as resectable malignant tumors of craniofacial skeleton.
