下顎骨に発生したエナメル上皮線維肉腫の1例

治療と腫瘍切除後の下顎骨再建について

抄録

Good progress has recently been reported in the reconstruction of the mandible after resection in the treatment of tumors. However, younger patients undergoing resection during the period of growth are left with many problems, both esthetic and functional.
Good results were obtained in the successful restoration of severe disorders. Correction of occlusal malfunction and esthetic improvement were obtained with reconstruction of the mandible by osteotomy and bone graft after the cessation of mandibular growth.
A 13-year-old patient underwent mandibular resection from the premolar area to the condyle and dissection of the upper right neck in the treatment of ameoblastic fibrosarcoma. Reconstruction using fresh autogenous iliac bone was performed at 18 years.
However post-operative bone growth resulted in severe jaw deformity. Therefore, secondary reconstruction was performed, involving vertical osteotomy at the region between the canine and first premolar on the left side and the distal region of the right canine, and a left sagittal splitting procedure (parallel method) of the ramus. Fresh autogenous iliac bone was then grafted to complete correction.
