涎石病在人群中的发生率为1.2％,其中80％～92％发生于颌下腺,6％～19％发生于腮腺,1％～2％发生于舌下腺及其它小涎腺。涎石堵塞导管,可导致唾液淤滞和急性疼痛,日后可并发细菌感染或形成脓肿。取出结石是缓解症状的唯一方法,目前对涎腺结石多主张手术治疗。对位于导管远中端的结石,可通过分离、扩张导管而取出结石;对于腺实质内或邻近腺体的 The incidence of salivary stone disease in the population was 1.2%, of which 80% to 92% occurred in the submandibular gland, 6% to 19% occurred in the parotid gland, 1% to 2% occurred in the sublingual glands and other small salivary glands. Salivary stones block the catheter, can lead to saliva stasis and acute pain in the future may be complicated by bacterial infection or the formation of abscesses. Remove the stones is the only way to alleviate the symptoms, the current advocate of salivary gland stones surgery. For the stones located at the distal end of the catheter, the stone can be removed by separating and dilating the catheter; for the gland within or adjacent to the gland
