Familial Gigantiform Cementoma: Life-Saving Total Midface Resection and Reconstruction Using Virtual Surgical Planning and 3D Printed Patient-Specific Implant-A Clinical Study.

ABSTRACT

Background: Familial gigantiform cementoma (FGC) is a rare benign fibrocemento-osseous lesion of the jaw characterized by well-circumscribed, extensive, mixed radiolucent-radiopaque masses in the mandible and the maxilla that can cause severe facial deformity. This condition is extremely rare with less than 40 cases reported in the literature. Purpose: The purpose of the paper is to highlight the importance of virtual surgical planning and patient-specific implant in the treatment of a complex lesion and reconstruction of the facial skeleton. The clinical presentations, and diagnostic challenges encountered when managing the lesion have been discussed in this article with emphasis on the treatment plan. Method/Surgical plan The sequence of treatment planned was resection of the lesion and immediate reconstruction with a patient-specific implant to improve the patient's quality of life. The management of FGC was a challenging one keeping in mind the rapid expansion of the lesion, widespread involvement of the jaws, and needs of the pediatric patient. Conclusion: Virtual surgical planning (VSP) along with 3D printed implant was instrumental in reconstructing the facial form of the child where the maxilla was completely resected and rehabilitation provided support to the vital structures of the face.
