Ultrasonographic examination of intraosseous jaw pathologies may reveal interesting incidental, mobile hyperechoic particles ("snowflakes") in anechoic areas. Purpose of this study is to explain and discuss this snowing-like ultrasonographic feature of intraosseous jaw pathologies. This study included 113 patients admitted to our clinic for examination: 43 (38.05%) males and 70 (61.9%) females with a mean age of 34.9 ± 17.2 years (range: 6-72 years). A total of 120 intraosseous lesions were evaluated prior to surgery using ultrasonography; these included non-neoplastic, odontogenic, and non-odontogenic lesions. In total, 5 (4.1%) of the 120 lesions exhibited snowing-like feature on ultrasonography, including 2 (1.6% of total) of 3 incisive canal cysts, 2 (1.6% of total) of 7 dentigerous cysts, and 1 (0.8% of total) of 19 odontogenic keratocysts. Snowflakes evident on ultrasonography of intraosseous jaw lesions may be specific to certain pathologies. Future studies correlating radiologic and pathologic features of intraosseous jaw lesions should focus on ultrasonographic snowing-like appearance in different types of lesions and explore why they occur.
对颌骨骨内病变进行超声检查时，可能会在无回声区域发现有趣的偶然出现的、可移动的高回声颗粒（“雪花”）。本研究的目的是解释和讨论颌骨骨内病变这种类似下雪的超声特征。本研究纳入了113名到我们诊所接受检查的患者：43名（38.05%）男性和70名（61.9%）女性，平均年龄为34.9±17.2岁（范围：6 - 72岁）。术前共使用超声评估了120处颌骨骨内病变；这些病变包括非肿瘤性、牙源性和非牙源性病变。在这120处病变中，共有5处（4.1%）在超声检查时表现出类似下雪的特征，其中包括3例切牙管囊肿中的2例（占总数的1.6%）、7例含牙囊肿中的2例（占总数的1.6%）以及19例牙源性角化囊肿中的1例（占总数的0.8%）。颌骨骨内病变超声检查中出现的雪花可能是某些病变所特有的。未来将颌骨骨内病变的放射学和病理学特征相关联的研究应聚焦于不同类型病变中的超声类似下雪的表现，并探究其出现的原因。
