A total of 42 patients presenting with recurrent unilateral parotid gland swelling was studied. Plain radiology of 38 patients with proved calculi showed that the lateral view is valueless. The anteroposterior view was positive in 58 per cent, and when coupled with an intrabuccal view 71 per cent of the calculi were radio-opaque. The overwhelming majority of calculi were visible as filling defects on sialography, while in 4 patients an area of narrowing with dilatation of the parotid duct proximal to it represented the site of the calculus. In the remaining 4 patients with the latter sign, repeat sialography showed normal appearances in 2, suggesting that the calculi had passed.
对42例复发性单侧腮腺肿胀患者进行了研究。38例经证实有结石的患者的普通X线检查显示，侧位片无价值。前后位片的阳性率为58%，与颊内位片联合使用时，71%的结石在X线下显影。绝大多数结石在涎腺造影中表现为充盈缺损，而在4例患者中，腮腺导管近端出现狭窄并伴有其近端扩张的区域代表结石部位。在其余4例有后一种征象的患者中，重复涎腺造影显示2例正常，提示结石已排出。
