To evaluate prospectively the recently developed method of extracorporeal shock-wave treatment of stones of the parotid gland.
76 patients with symptomatic, sonographically proven, solitary stones of the parotid gland (36 females, 40 males; aged 2-80 years) were treated with extracorporeal piezoelectric shock-wave lithotripsy (ESWL) after failed conservative management (sialagogues, gland massage, duct bougie dilation).
Parotid stones were no longer demonstrable after a mean follow-up time of 48 (6-71) months in 38 of the 76 patients; they were symptom-free and no new stones had formed. A residual, but symptom-free, stone was found in another 20 patients (26%) of whom 13 (17%) reported marked improvement after ESWL. No change from pretreatment symptoms occurred in five patients (7%) so that operative removal had to be performed. The success rate of the lithotripsy was independent of size and site of the stone.
ESWL is the method of first choice in the treatment of parotid gland stones after unsuccessful conservative treatment and obviates operative gland removal in most cases.
前瞻性评估最近开发的体外冲击波治疗腮腺结石的方法。
76例经超声证实为腮腺单发有症状结石的患者（女性36例，男性40例；年龄2至80岁），在保守治疗（使用催涎剂、腺体按摩、导管探条扩张）失败后，接受了体外压电冲击波碎石术（ESWL）治疗。
76例患者中，38例在平均随访48（6至71）个月后腮腺结石不再显示；他们无症状，且未形成新的结石。另外20例患者（26%）发现有残留但无症状的结石，其中13例（17%）报告ESWL后有明显改善。5例患者（7%）的症状与治疗前无变化，因此必须进行手术切除。碎石术的成功率与结石的大小和位置无关。
ESWL是保守治疗失败后腮腺结石治疗的首选方法，在大多数情况下可避免手术切除腺体。
