Abstract
Extensive bilateral midfacial defects including the upper jaw, palate, and sinuses present a formidable reconstructive challenge. Prosthetic restorations require a solid anchor point to be successful, since orofacial motion would otherwise cause instability of the prosthesis. We report on a series of eight patients who underwent transmalar placement of a Steinmann pin at the time of definitive tumor resection. The Steinmann pin was used immediately to securely anchor a prosthesis to the skull base. The maximum follow-up time is 9 years. The Steinmann pin has remained firmly anchored without significant loosening in six of these eight patients, and no major complications have resulted from its use. In conclusion, the transmalar Steinmann pin is an effective and immediate single-stage method of permanently retaining a midface prosthesis.
