Reconstructive Facial Surgery Techniques

Background: Liposarcoma is considered one of the most frequently occurring tumors of the soft tissues, representing 17% to 30% of all mesenchymal cell tumors. It is less common in the head and neck representing <10% of tumors in this region. The reconstruction of defects derived from resection of these tumors presents a surgical challenge. New three-dimensional digital technologies allow more exact surgery, cause less morbidity, and achieve adequate aesthetic outcomes. Objective: The aim of this article was to describe the complex reconstruction of a defect caused by the resection of a liposarcoma in the temporal region. Methods: Three-dimensional technology allowed patient planning and a reconstruction that was as exact as possible. A made-to-measure polymethyl methacrylate prosthesis was used to correct the defect in the zygomatic arch. The temporal fossa was covered with a standard porous polyethylene prosthesis. Conclusions: Satisfactory esthetic and functional results were achieved using three-dimensional digital technology for treatment planning and to fabricate a made-to-measure polyethylene prosthesis and surgical guide.
