颌下腺结石取石术后腺体功能的恢复

Recovery of submandibular gland function following transoral sialolithectomy

目的研究颌下腺结石取石术后腺体功能的恢复情况。方法用９９ｍＴｃ动态显像法检测２６例颌下腺结石取石术对腺体功能的影响。结果单纯取石术后，腺体功能的近期恢复率较高，而远期功能呈下降趋势；腺体感染是影响术后功能恢复的关键因素，结石大小和患者年龄对功能恢复也有一定影响。结论在颌下腺结石治疗中，有效阻断结石形成前的一系列病理过程，控制炎症的发生、发展，对防止腺体功能降低有重要意义；取石术后，保持颌下腺导管的正常开口位置、合理使用催涎剂。

Objective Investigate the recovery of the submandibular gland function following transoral sialolithectomy. Methods The glandular function of 26 patients who received the transoral sialolithectomy were investigated by sequential scintigraphy with 99m Tc pertechetate.Results Most glandular function recovers normal in short time after operation. Glandular infection, calculus diameter and patients's age could influence the recovery of function. Conclusion In the treatment of sialolithiasis, breaking up the pathogenic process of calculus formation and effectively controlling the glandular infection are very important in preventing from the function reduction. After transoral sialolithectomy preserving the anatomical normal orifice of the duct, and using silivators may be very favorable for the function recovery.
