造釉细胞瘤是颌骨最常见的牙源性上皮性肿瘤,好发于青壮年,绝大多数发生在下颌骨。由于初期无明显自觉症状,常常等到肿瘤有足够大小,引起面颌畸形,导致功能碍障,或合并感染,才开始就诊。造釉细胞瘤是局部呈浸润性生长的低恶性或具有复发倾向的肿瘤。比较保守的治疗常有很高的复发率。根据同内外学者的观察:刮治术的复发率为15～100%。多次复发可能恶变。因此很多学者认为,造釉细胞瘤的常规治疗,应采取颌骨整块切除。但整块 Ameloblastoma is the most common odontogenic epithelial tumor of the jaw. It occurs in young adults and the vast majority occurs in the mandible. Due to no apparent symptoms at the initial stage, it often waited until the tumor had a sufficient size to cause facial jaw malformations, leading to functional impairment, or co-infection. Ameloblastomas are localized, invasive, low-grade or recurrent tumors. More conservative treatments often have high recurrence rates. According to observations from inside and outside scholars, the recurrence rate of curettage is 15-100%. Multiple relapses may be malignant. Therefore, many scholars believe that the routine treatment of ameloblastoma should be taken to remove the entire jaw. But the whole block
