To estimate the utility of ultrasonography in diagnosis and differentiation of pleomorphic adenomas.
From the group of 88 patients examined by ultrasound, who were referred because of the tumor in the preauricular area, submandibular area, or cheek, pleomorphic adenoma was finally diagnosed in 24 (with multiple recurrent tumors in 2 patients).
Ultrasound was able to differentiate between benign and malignant lesions with 96% accuracy in this study. Predicting that the detected tumor was pleomorphic adenoma was possible with up to 84% accuracy. In 15 of 22 patients with primary pleomorphic adenoma, ultrasound guided fine-needle aspiration biopsy. High-resolution probes and harmonic imaging enabled demonstrationof histopathologic heterogeneity of pleomorphic adenomas (in 16 primary tumors [73%]). Of primary pleomorphic adenomas, 95% (21/22) had 5 or fewer vessels detectable in the whole lesion.
Modern ultrasound is highly valuable, useful, and reliable in differential diagnosis of tumors in the preauricular area, submandibular area, and cheek. It enables precise localization, measurements, and assessment of the structure of lesions. It may be the first and last imaging method needed to formulate the final diagnosis, or it may guide fine-needle aspiration biopsy. In many cases, ultrasound may also suggest the nature of the tumor.
评估超声检查在多形性腺瘤诊断及鉴别诊断中的应用价值。
对88例因耳前区、下颌下区或颊部肿物而接受超声检查的患者进行研究，最终确诊多形性腺瘤24例（其中2例为多次复发肿瘤）。
本研究中，超声鉴别良恶性病变的准确率达96%。预测所检测到的肿瘤为多形性腺瘤的准确率高达84%。在22例原发性多形性腺瘤患者中的15例，超声引导下进行了细针穿刺活检。高分辨率探头及谐波成像能够显示多形性腺瘤的组织病理学异质性（16例原发性肿瘤[73%]）。原发性多形性腺瘤中，95%（21/22）在整个病变中可检测到5条或更少的血管。
现代超声在耳前区、下颌下区及颊部肿瘤的鉴别诊断中具有很高的价值，实用且可靠。它能够实现病变的精确定位、测量及结构评估。它可能是做出最终诊断所需的第一种也是最后一种成像方法，或者可用于引导细针穿刺活检。在许多情况下，超声还可提示肿瘤的性质。
