目的：探讨超声对腮腺肿瘤的诊断与鉴别诊断价值。方法：回顾性分析经手术病理证实的173例腮腺肿瘤的声像图资料。结果：173例腮腺肿瘤中，良性159例，超声诊断符合率71.1%（113/159），恶性14例，超声诊断符合率71.4%（10/14）。良性病变常表现为形态规则边界清楚的肿块，以混合瘤居多，其次为腺淋巴瘤；恶性病变常表现为形态不规则，边界不清晰的肿块，以黏液表皮样癌居多。良恶性肿瘤在形态、边界、包膜、有无液化（囊实混合）、钙化及CDFI等表现方面差异有统计学意义（P<0.05）。结论：高频彩超是腮腺良恶性肿瘤鉴别诊断的重要方法。

Objective:To assess the value of ultrasonography in diagnosis and differential diagnosis of parotid tumors. Methods:A retrospective analysis was done for data of ultrasonograms of 173 patients with parotid tumors confirmed by surgery and pathol-ogy. Results:Of 173 cases,there were 159 benign tumors,the conform rate was 71.1% (113/159);there were 14 malignant tum-ors,the conform rate was 71.4% (10/14). Benign tumors demonstrated regular shape and clear margin. Among the 159 benign tu-mors pleomorphic adenomas were most common,followed by adenolymphoma. While the malignant cases were showed as irregular masses with unclear margin. The most common malignant tumors were mucoepidermoid carcinoma. Our study indicated that be-tween benign and malignant tumor,the difference of the sample rate in shape,border,envelope,with liquefaction (complex cystic and solid) or calcification and color Doppler flow imaging of benign and malignant tumor were statistically significant (P<0.05). Conclusions:The high frequency color Doppler imaging is an important method in judging the characteristics of parotid tumors. But it is difficult to totally coincide with pathological diagnosis to other parotid tumors.
