颌下腺导管膝状弯曲部,即导管弯曲绕过下颌舌骨肌后缘的急转弯部结石,治疗意见分歧很大。大多数学者推荐切除颌下腺。有些学者却主张包括上述部位在内的所有颌下腺结石都能成功地从口内摘除。Dechau-me等认为一旦去除阻塞物,颌下腺就有显著的功能恢复能力。他们建议从口内摘除全部结石,即使结石位于颌下腺导管深部。本文研究结果支持后一种观点。作者从1974年1月至1979年12月,对一侧颌下腺正常,一侧患颌下腺导管膝状弯曲部结石患者,按Sewerd的手术方法经口内切开取除结石,并追踪观察至少一年,共21例。复查时,询问病人术后有无阻塞或炎症症状;作临床和X线照片检查了解有无复发的结
Submandibular gland duct knee flexion, that is, the catheter bent around the posterior edge of the hyoid muscle of acute turn stones, the treatment of opinions vary widely. Most scholars recommend resection of the submandibular gland. Some scholars have argued that all submandibular gland stones, including the above, can be successfully removed from the mouth. Dechau-me and others think that once the obstruction is removed, the submandibular glands have significant functional recovery. They suggest removing all stones from the mouth, even if the stone is deep in the submandibular gland duct. The results of this article support the latter view. The author from January 1974 to December 1979, one side of the normal submandibular gland, one side of the submandibular gland duct knee flexion stones patients, according to Sewerd's surgical approach to remove stones by mouth, and follow-up observation of at least one year, A total of 21 cases. Re-examination, the patient asked whether there is obstruction or inflammation; for clinical and X-ray examination to see whether the recurrence of the knot
