摘要
唾液腺攝影是一種過程簡單且對病人無傷害的檢查，但需要耐性和熟巧的技術，導管放在士丹省氏管(Stensen's duct, Parotid gland)或華通氏管(Wharton's duct, submaxillary gland)後，祗打少量顯影劑（約1-1.8CC）便可以攝影，一般祗需正面和側面兩個部位。正常的唾液腺映像，其分枝、實質均勻分佈，與肺部的支氣管、小支氣管和腺包分佈情形無異。有疾病時，唾液腺的結構因此而改變，L有結石時，其前、後端之管會擴張，甚至引起阻塞現象，由此可知結石的部位和結石的大小。2．慢性發炎時，腮腺(Parotid gland)或頜下腺(Submaxillary gland)的管會變粗細不一致(alternating dilatation and stricture)，管緣變不規則，管的末端，腺泡部份擴張(sialectasis)，或是管內無法充滿顯影劑。變化的程度與病變的輕重一致。3．腫瘤、良性腫瘤(benignt tumor)一腫瘤附近之管變直，發生移位，實質(Parenchyma)沒有顯影劑灌入(filling defect)；至於惡性腫瘤－腺管發生移位(displacement)、扭歪(distortion)、變直(stretching)，甚至破壞(destruction)，顯影劑在管或實質內充滿不全，且不規則的貯留(irregular puddling)在腫瘤內。不過，很多時良性與惡性腫瘤的區分，祗憑sialopraphy，是不容易作一肯定的鑑別診斷，可幸的是惡性腫瘤發生率不高，只佔8.9%而已。然而，唾液腺攝影，可告知腫瘤的大小和範圍，這對於耳鼻喉科醫師治療和開刀之進行計劃，是有所幫助的。台大醫院放射線科從1973年6月到1981年8月，從事了268個病人作311次唾液腺攝影檢查，共有46個正常唾液腺，95個病例為慢性發炎，116個病例為腫瘤（其中包括98個病例是唾液腺本身所發生的腫瘤，18個病例是發生在腺體外的），11個患者沒有作成功。本文根據此等病例的臨床、病理和X光變化作一分析，同時，患者接受唾液腺檢查的成功率(Successful rate)非常高，達96.46%，所以，唾液腺攝影可推薦為唾液腺疾病患者接受治療前的例行檢查。

Sialography is a method to get visualization of the ducts and parenchyma of the parotid and submaxillary glands by injection of radiopaque contrast material through the main secretory duct of the gland. It shows the normal and abnormal patterns of the ductal system and parenchyma, as stricture and dilatation of the ducts, dilatation of the acini (sialectasis). Those are the pathologic changes of inflammatory diseases. By the same way, sialography may confirm or deny the presence of a clinically suspected tumor, and give valuable information, relating to the location and extent of the mass. Three hundred and eleven sialographies for 268 cases were performed in recent 8 years (from June 1973 to August 1981) in the Department of Radiology of National Taiwan University Hospital. According to the clinical informations, radiologic findings and pathologic reports. These cases were reviewed and analyzed. The result reveals 46 cases of normal condition, 95 cases of inflammatory diseases, 116 cases of tumors and 11 cases of technic failure.
