Case report: Giant cell tumor of the mandible resected and restored with a fibular bone and dental implant

Abstract

Introduction: Giant cell lesions of the jawbone were distinguished from other lesions of the jaw in 1953 by Jaffe, who called them “regenerative giant cell granuloma”.1 Giant cell tumors are rare, usually in women in their 20s and 30s. Clinical case: Patient D, 21 years old, female. Medical history: In July 2021, due to swelling around the right cheek, she was treated with medicine when she went to the doctor. In November 2021, the lower right second molar was extracted, but the swelling did not decrease. She was received to the surgery department of a Mongolian-Japanese hospital with the pain of a painless enlargement of the right side of the jaw and loss of facial symmetry. Computed tomography, 5.1 x 3.4 x 6.0 cm covering the body, angle and ramus part of the right mandible, +18HU. +34HU. +45HU densities, a heterogeneous structure, irregular osteolytic destruction of the jaw bone and a large mass surrounded by an irregular wall are defined. As a result of the biopsy analysis, giant cell granuloma was diagnosed. Conclusion: It restored the defect caused by partial resection of the right side of the mandible with a fibula-free vascular flap. The tooth defect was restored with an implant-supported prosthesis. The jaw reconstruction surgery with vascularized free flap has been performed in Mongolia since 2011, and it is the first case of reconstruction with dental implant-supported prosthesis.
