摘要/Abstract

摘要： 目的　回顾发生于下颌骨成釉细胞瘤和角化囊性瘤的锥体束CT（CBCT）影像资料，寻找两者影像特点与鉴别诊断要点。方法：收集下颌骨原发性成釉细胞瘤和角化囊性瘤CBCT影像资料，分为成釉细胞瘤（AME）组和角化囊性瘤（OKC）组，对比观察两组CBCT影像特征。结果：AME组与OKC组纳入患者各20例，两组患者的年龄、性别及病灶部位、内部分隔均无显著统计学差异（P＞0.05;AME组病灶侧骨皮质膨隆程度（1.82±0.55）远高于OKC组（1.16±0.24）;AME组病灶侧颊和/或舌侧骨壁不连续17例，累及牙齿牙根吸收16例;OKC组病灶骨壁不连续共9例，累及牙齿牙根吸收3例，统计显示骨皮质膨隆、骨壁连续性以及累及牙根吸收情况两组具有显著差异（P<0.05）。结论：CBCT下病灶骨皮质膨隆程度、骨壁连续性以及累及牙根吸收的影像表现是鉴别下颌骨成釉细胞瘤与角化囊性瘤的重要指标。

Abstract: Objective　 To find the imaging features and essentials of identification and diagnosis through a comparative study on the CBCT image of the Amelobalstoma and Keratocystic odontogenic tumors occurring at the mandible. Methods CBCT images of primary ameloblastoma and Keratocystic odontogenic tumor of the mandible were collected. They were divided into ameloblastoma group (AME) and keratocystic odontogenic tumor group (OKC) based on the results of pathological diagnosis and the image features of patients in both groups were analyzed. Results Twenty cases of patients were included into AME group and OKC group equally, the difference in age, gender , position of lesion and interior separation between the two groups of patients were not statistically significant (P>0.05). The degree of distention of bone cortex at the side of lesion of AME group was （1.82±0.55）in average, while the counterpart of OKC group was （1.16±0.24）. In AME group ,there were a total of 17 cases of discontinuous bone wall at the buccal side and/or lingual side and 16 cases of tooth root were absorbed. In OKC group ,there were a total of 10 cases of discontinuous bone wall at the buccal side and/or lingual side and 3 cases of tooth root were absorbed.The statistical results showed that there were significant differences between the two groups in distention of bone cortex at lesion side, the continuity of bone wall and the absorption of root（P<0.05）.Conclusion Amid the CBCT image, the degree of distention of bone cortex at lesion side , continuity of bone wall and manifestation of dental and dental root resorption are the crucial indexes to identify Mandibular Ameloblastoma and Keratocystic odontogenic tumors.
