Complex craniofacial reconstruction using stereolithographic modeling.

Abstract

Stereolithographic modeling allows preoperative preparation and improved intraoperative precision by clearly displaying detailed anatomy in patients undergoing craniofacial surgery. There is a lack of plastic surgery literature describing this modality as a useful adjunct to reconstructive surgery of the craniomaxillofacial skeleton. Specifically, the ability to use mirror-image modeling to recreate patient anatomy using the unaffected side as a model presents an advantage that plastic surgeons should be aware of. We applied this technology in patients with major craniofacial defects requiring bony reconstruction and observed many qualitative benefits with respect to functional and cosmetic outcomes of reconstruction. This article presents stereolithographic modeling as a feasible and useful tool in complex head and neck/craniomaxillofacial reconstruction after tumor resection.
