上顎類腱型エナメル上皮腫に対して遊離腸骨ブロック移植後にカスタムメイド・チタンメッシュトレーと自家腸骨海綿骨細片で上顎骨二次再建を施行した1例

We report a case of desmoplastic ameloblastoma (DA) arising in the maxilla, which was reconstructed using a custom-made titanium mesh tray with particulate cancellous bone and marrow (PCBM) after an autogenous iliac bone graft. The patient was a 35-year-old man who was referred to our outpatient clinic to undergo assessment of a maxillary tumor. A swelling was found between the left lateral incisor and premolars. Radiographic findings showed a “frosted glass-like” lesion. We diagnosed DA on an incisional biopsy. Maxillectomy and reconstruction with an autogenous iliac bone graft were performed in June 2013. In addition, reconstructive surgery using a custom-made titanium mesh tray with PCBM was performed subsequently. After the operation, we placed dental implants and provided the final prosthesis. There has been no recurrence of tumor as of 5 years after the maxillectomy and reconstructive surgery. Furthermore, a good esthetic outcome with recovery of the occlusion function was obtained.
