牙源性粘液瘤误诊分析——附42例X线研究

ROENTOGENOGRAPHIC STUDY OF 42 CASES

目的：总结１９６４—１９９８年华西医科大学口腔医院收治的经病理证实的４２例牙源性粘液瘤，分析误诊原因，提高对本病的认识。方法：复习４２例病人的临床、Ｘ线资料。结果：Ｘ线表现复杂多样，可分为Ⅴ型。Ⅰ型：牙槽突破坏型；Ⅱ型：单囊型；Ⅲ型：多囊型；Ⅳ：蜂窝型；Ⅴ型；恶性征型。术前诊断７例符合，３５例误诊，误诊率达８３．３３％。结论：Ｘ线表现的复杂多样化是牙源性液液瘤误诊的主要原因，应与造釉细胞瘤、骨纤维异常增殖症、骨化纤维瘤、恶性肿瘤鉴别。

Objective: retrospect 42 cases of Odontogenic myxoma during 19641998, in order to analysis the causes for erroneous diagnosis and promote our knowledge to this tumor. All the cases were confirmed pathologically. Methods: Review all the clinic and roentgenographic materials of 42 cases. Results: It shows complicated and various radiographic appearances. We divide in into five types: alveolar bone destroyed type, unicystic type, multicystic type; honeycombed type; malignantlike type. Preoperatively seven cases were correct diagnosed and the rest were erroneous diagnosed. The erroneous diagnosis rate is 83.33%. Conclusions: The main cause of erroneous diagnoses of odontogentic myxoma is the complication and variety of radiographic apperances. They should be differentiatied with Ameloblastoma, Fibrous dysplasia, Osteofibroma and malignant tumors.
