以面中骨肉剝離術處理巨大上頜牙骨質骨化纖維瘤

牙骨質骨化纖維瘤(cemento-ossifying fibroma)是一種少見之良性纖維骨性腫瘤，可能源自間葉質母細胞，與牙周膜也有關，多發生於女性及下頜骨；生長緩慢，常因外觀變形或壓迫週遭器官而就醫；處理方式為手術切除。本例病人為57歲男性，因左臉頰腫塊而來就醫，自述已有30年之久，緩慢變大，約6×6×5cm。經理學檢查與影像學檢查後，初步診斷為纖維骨性病變或良性腫瘤，於是安排經面中骨肉剝離術進行腫瘤切除與上頜骨重建手術，術後病理報告為牙骨質骨化纖維瘤。病人於門診持續追蹤已3年，無明顯併發症也無腫瘤復發。

Cemento-ossifying fibroma is a rare benign fibro-osseous tumor that habors fibrous stroma mingled with osteoid and cementum. It is thought to be derived from mesenchymal progenitor cells and in close relationship to the periodontal ligament. It is more commonly found in female and in the mandible. Patients often seek for help for its mass effect years later. Treatment should be directed toward complete excision of the mass. We report a 57-year-old male patient bothered by a facial mass measuring about 6×6×5cm with slow-growing nature for 30 years. Physical examinations and image study suggested a fibrous-osseous lesion or a benign osseous tumor. The tumor was extirpated using midfacial degloving and reconstructed with Titanium plate. The pathological study unveiled the diagnosis of cemento-ossifying fibroma subsequently. The patient has been regularly followed at our OPD for 2 years without major sequale and tumor recurrence.
