Sialolithiasis is the formation of a stone within the salivary gland, and approximately 80% of them occur within the submandibular gland. Sialolithiasis can lead to swelling and pain of the gland in the immediate phase and if left untreated, can lead to sialadenitis and even atrophy of the gland. Certain factors have already been established in the formation of sialolithiasis such as dehydration, tobacco smoke, autoimmune disorders and certain medications. One factor we theorise contributes to the formation of sialolithiasis is bony outgrowths on the tongue surface of the jaw, called mandibular tori. These outgrowths can lead to external compression of the submandibular duct, which leads to impeded salivary flow and the potential for sialolith formation. We present two cases in which individuals had submandibular sialolithiasis in the setting of extensive mandibular tori.
涎石病是唾液腺内形成结石，其中约 80%发生于下颌下腺。涎石病可导致腺体在急性期肿胀和疼痛，如果不治疗，可导致涎腺炎甚至腺体萎缩。某些因素已被确定在涎石形成中起作用，如脱水、烟草烟雾、自身免疫性疾病和某些药物。我们推测导致涎石形成的一个因素是颌骨舌面的骨性突起，称为下颌隆突。这些突起可导致下颌下腺管外部受压，导致唾液流动受阻和涎石形成的可能性。我们介绍了两个下颌隆突广泛存在的下颌下腺涎石病患者的病例。
