目的探讨超声对口腔软组织肿块病变的诊断价值和诊断方法。方法本研究纳入2017年1月至2019年12月接受超声检查和组织病理学检查的肿块病变（肿瘤病变和囊肿）患者。以下几点由两名观察员使用评估量表进行评估：血管状况、回波强度水平、边界、边缘形状、内部回波分布和包膜。统计分析各点对肿瘤病变和囊肿鉴别诊断的有用性。结果共检出口腔软组织肿块45例，其中肿瘤33例，囊肿12例。肿瘤病变与囊肿在血管活度、回声强度、边界和边缘形状四个评价点上存在显著差异。囊肿几乎完全排除诊断，特别是当观察到血管。非血管性肿瘤病变与囊肿在回声强度和边界两个评价点上也存在显著差异。结论在口腔肿块的超声检查中，当观察到血管分布时，可以诊断肿瘤病变并排除囊肿。然而，当没有观察到血管时，肿瘤病变和囊肿可以通过两个评价点来识别：回声强度水平和边界。
ObjectivesTo examine the diagnostic usefulness and procedures of ultrasonography (US) for mass lesions in the soft tissue of the oral region.MethodsThis study involved patients with mass lesions (tumorous lesions and cysts) who had undergone US and histopathological examinations from January 2017 to December 2019. The following points were evaluated by two observers using an evaluation scale: vascularity, echo intensity level, boundary, margin shape, distribution of internal echoes, and capsule. The usefulness of each point for differential diagnosis of tumorous lesions and cysts was statistically analyzed.ResultsForty-five mass lesions in the soft tissue of the oral region (33 tumorous lesions and 12 cysts) were analyzed. There were significant differences in four evaluation points between the tumorous lesions and cysts: vascularity, echo intensity level, boundary, and margin shape. Cysts were almost completely excluded diagnostically, especially when vascularity was observed. There were also significant differences in two evaluation points between nonvascular tumorous lesions and cysts: echo intensity level and boundary.ConclusionsIn US examination for mass lesions in the oral region, it was possible to diagnose tumorous lesions and exclude cysts when vascularity was observed. When vascularity was not observed, however, tumorous lesions and cysts could be identified using two evaluation points: echo intensity level and boundary.
