副腮腺及其病变的超声研究

目的探讨超声在副腮腺病变中的定性和定位价值。方法采用直接探查法,用声像图观察副腮腺的大小、内部回声及副腮腺内部有无肿块,肿块的大小、边界、形态,用CDFI观察血流情况。结果超声对副腮腺肿块的定位正确率为79%,较造影、CT、MRI比有其优势;对副腮腺肿块的定性正确率达到84%。结论超声检查是区别面颊部肿块是否来源于副腮腺还是软组织的较好的方法,可以给临床医师的术前定位、定性提供参考。

Ultrasonographic Characteristics in Accessory Parotid Gland and its Pathological Changes

Objective To study the ultrasound's value of quality and localization in lesion of accessory parotid gland. Methods Directly probing was used to observe accessory parotid gland's size,inner echo,and lump through sonography.The lump was detected by it 's size,border,and form.We also observed the situation of blood flow with CDFI .Results The accuracy of ultrasound which localized the access ory parotid gland is 79%.It is superior to contrast,CT,MRI.The accuracy of ult rasound which qualify the accessory parotid gland is 84%. Conclusions Ultrasonography is a better medium to distinguish w hether the lump comes from cheek or accessory parotid gland.It could provide co nsultant opinion before operation for doctors.
