高频超声在潜突型舌下腺囊肿中的作用

目的:评价超声对潜突型舌下腺囊肿的诊断价值及临床意义。方法:对36例术前经超声检查、术后经病理诊断的潜突型舌下腺囊肿进行回顾性分析总结。结果:超声正确诊断32例,误诊4例,正确率88.9%。囊肿边界尚清晰,无明显包膜或包膜纤细且不连续。24例囊肿外形呈“漏斗形”改变。28例内部液性暗区清晰,8例欠清晰且内伴数量不等的中等粗光点或线状分隔。36例囊肿均显示与患侧舌下腺无关,24例囊肿致同侧颌下腺受压或变形且致其向外下方移位。结论:超声是诊断潜突型舌下腺囊肿的重要辅助手段,其方法高效无创并对临床诊治具有重要的指导意义。

The diagnostic value of high-frequency ultrasound for plunge ranula

Objective:To evaluate the diagnostic value and clinical meaning of high-frequency ultrasound for plunge ranula. Methods: Thirty-six cases of plunge ranula were analyzed and summarized retrospectively, which were confirmed by postoperative biopsy. Results: Thirty-two cases of plunge ranula were correctly diagnosed by high-frequency ultrasound, and 4 cases were misdiagnosed. The accurate rate was 88.9%. The border of cysts was clear. Most cysts have no capsule. Although a few of them had capsule, but it was not complete. The form of the cyst in 24 cases was infundibular in shape, in 28 cases the interior content of the cyst showed echo free, in 8 cases the echo free was not very clear and had some medium light spots and septations. All of the 36 cases of plunge ranula showed no relationship with the sublingual gland of the diseased side. The submaxillary gland of 24 cases was compressed and shifted inferiorly and laterally. Conclusion: High-frequency ultrasound is without harm and has high efficiency, it is an important method for the diagnosis of plunge ranula.
