OBJECTIVES
To study the radiographic sequence in the recurrence of unicystic ameloblastoma following marsupialization.
MATERIALS AND METHODS
Retrospective analysis of three cases of uncystic ameloblastoma.
RESULTS
Six distinct stages were identified in all three cases: bone regeneration starting at the periphery of the cavity; appearance of a diffusely sclerotic band; appearance of scalloping; expansion of scalloping; formation of a multilocular pattern; and enlargement of the cystic lesion.
CONCLUSION
The first radiographic sign of recurrence is scalloping of the sclerotic margin of the regenerated bone.
目的
研究袋形术式治疗单囊性成釉细胞瘤复发的影像学表现序列。
材料与方法
对3例单囊性成釉细胞瘤进行回顾性分析。
结果
所有3例均发现6个不同阶段：腔周开始骨再生；出现弥漫性硬化带；出现扇贝样改变；扇贝样改变扩大；形成多房样形态；囊性病变增大。
结论
复发的首个影像学征象是再生骨硬化边缘出现扇贝样改变。
