Maxillary reconstruction using a multi-element free fibula flap based on a three-dimensional polyacrylic resin model

Abstract

Preoperative preparation of working models of the skull and free bone flaps using the digital print technology and photocured polyacrylic resins may be of a great benefit to the patient, for whom a virtual resection and reconstruction procedure may be planned in detail and performed. The purpose of mid-facial reconstruction using 3D models is to plan a functional mid-facial reconstruction procedure in order to restore supportive function of intraorbital structures and to make placement of dental implants and further prosthetic rehabilitation possible.Maxillary and mid-facial reconstruction using a free fibula flap based on a three-dimensional working model was performed in a patient diagnosed with a squamous cell carcinoma of the left maxillary sinus penetrating to the orbit, the ethmoid complex, and the pterygopalatine fossa. The use of three-dimensional polyacrylic models allowed for detailed preoperative planning and a virtual resection and reconstruction procedure with a highly satisfying functional and cosmetic effect. A procedure based on methods discussed here may be significantly shorter and more precise.
