環口放射線片已經成為台灣牙醫常規的檢查項目，本文主要是描述Stafne缺陷的臨床及放射線影像的特徵。這類缺陷最常在中年病患常規的放射線檢查中意外被診斷出來。手術方式對於診斷並沒有太大的助益，由手術取得的組織在病理學的檢查顯示一些分泌腺或是結締組織。藉由電腦斷層及立體影像重建可以比較保性的診斷出此類舌側缺陷是源自於周圍組織。此類的缺陷不會發生惡性變化。因此由保守性的電腦斷層檢查就足以做出診斷，這種病蛙為發育性的缺陷，而非顎骨內的腫瘤，定期的檢查追蹤即可，不須要進一步的手術治療。

Panoramic film has becomes a routine radiological examination in dental clinic in Taiwan. The objective was to describe the clinical and radiological characteristics of patients with Stafne's defect. The most cases have been reported in middle aged and old adults. The entity was diagnosed incidentally during a routine radiology in this case report. The surgical intervention don't offer much help to confirm the diagnosis. Grandular tissue and tiny connective tissue was found within the lesions. The computer tomography and three-dimentional reconstruction demonstrated the conservation of the lingual cortical and the peripheral origin of the lesion. No progressive changes were found in our cases. Stafne's bone cavity was an incidental finding, presenting no progressive changes. Complememtary technique such as CT are sufficient to establish a certain diagnosis.
