【摘要】 目的:分析10例下颌下腺导管内异物结石临床特点,进一步认识下颌下腺导管结石的形成过程。方法:对10例下颌下腺导管结石患者,分析其临床和X线表现进行诊断,局麻下口底黏膜切口导管切开手术取石。结果:10例患者诊断明确,手术取石顺利。结石外形均为长圆锥形和梭形,近导管口端较粗,近腺体端较细,表面多为颗粒粗糙面,以异物为中心钙化形成结石,异物种类:鱼骨(刺)7例,植物茎2例,毛发1例。结论:异物为中心形成涎石,以客观实例来说明涎石形成的核心说。更多还原

【Abstract】 Objective:To analyze clinical characteristics of 10 cases of submandibular gland duct foreign body stone in an attempt to have further understanding of how the stone formed.Methods:Ten of submandibular gland duct stone were diagnosed by analizing clinical and X-ray manifestations and treated by incising the mucosa of oral floor and lateral wall of duct to remove calculi under local anesthesia.Results:The 10 cases were diagnosed definitely and the calculi were removed successfully.The stones were conico-acuminate and fusiform in shape.Generally,the calculous diameter to the side of ductal orifice was bigger than the side of the gland.The surface of stones was rough and granular.The calcification by foreign body as a center caused the formation of the calculi and the foreign body was fish bone(spicule) in 7 cases,plant stem in 2 cases and hair in one case.Conclusion:The fact that the calcification by foreign body as a center caused the formation of sialolith in the 10 cases illustrates the core hypothesis of sialolith formation.to更多还原
