The purpose of this study was to investigate whether the findings of Tc-99m pertechnetate salivary gland scintigraphy (SGS) can predict the outcome of sialoendoscopic intervention in patients with obstructive submaxillaritis.
Eleven patients with obstructive submaxillaritis were prospectively recruited. All patients underwent sialoendoscopy. Tc-99m pertechnetate SGS was performed both before and after sialoendoscopy.
Sialoendoscopy was effective in the glands with tracer uptake (n = 9) demonstrated on SGS before the procedure, evidenced by not only relief of the symptoms but also improvement in excretion in post therapy salivary gland scintigraphy. In contrast, sialoendoscopy was ineffective in the glands without tracer uptake (n = 2) in pretherapy scans.
In patients with submaxillaritis, whether a sialoendoscopy should be performed depends on the results of salivary gland scintigraphy.
本研究旨在探讨 Tc-99m 过锝酸盐唾液腺闪烁显像（SGS）的结果是否可以预测唾液腺内镜介入治疗阻塞性下颌下腺炎的效果。
前瞻性招募了 11 例阻塞性下颌下腺炎患者。所有患者均接受了唾液腺内镜检查。在唾液腺内镜检查前后均进行了 Tc-99m 过锝酸盐 SGS。
SGS 显示术前有示踪剂摄取的腺体（n = 9）的唾液腺内镜检查有效，不仅症状缓解，而且治疗后唾液腺闪烁显像显示排泄功能改善。相比之下，术前扫描未见示踪剂摄取的腺体（n = 2）的唾液腺内镜检查无效。
在患有下颌下腺炎的患者中，是否进行唾液腺内镜检查取决于唾液腺闪烁显像的结果。
