超声检查已广泛应用于头颈部病变如颈部淋巴结、涎腺异常以及面部骨折的辅助诊断。 作者复习了1992～1996年间11例经外科手术的腭部涎腺肿瘤,男性4例,女性7例,年龄10～75岁。检查方法是使病人仰卧并张大口,用水或耦合剂作为传导介质,将探头直接对准病变区域扫描。所有超声检查均采用10MHz的超声诊断仪。7例病理诊断为多形性腺瘤,2例为粘液表皮样癌,1例为未分化癌,1例为多形性腺瘤内癌。对超声扫描图像的分析包括肿瘤边界、包膜的完整性、后回声或后壁回声 Ultrasonography has been widely used in the diagnosis of head and neck lesions such as cervical lymph nodes, salivary gland abnormalities and facial fractures. The authors reviewed 11 cases of surgically treated salivary gland tumors in the palate from 1992 to 1996, including 4 males and 7 females, aged 10-75 years. Check the method is to make the patient supine and large mouth, water or coupling agent as a conductive medium, the probe directly at the lesion area scan. All ultrasound tests were performed using a 10 MHz ultrasound scanner. Seven cases were diagnosed as pleomorphic adenoma, two as mucoepidermoid carcinoma, one as undifferentiated carcinoma and one as pleomorphic adenoma. Analysis of the ultrasound scan image includes tumor boundaries, envelope integrity, posterior echo, or posterior wall echo
