高频彩超对腮腺及颌下腺的23例混合瘤的临床回顾性分析(1)
【摘 要】
目的评价高频彩超对腮腺及颌下腺混合瘤的超声诊断价值。方法对23例经手术病理证实的腮腺及颌下腺的混合瘤进行回顾性分析。结果其中13例发生在腮腺,9例发生在颌下腺,1例为多发性,腮腺及颌下腺均有。误诊2例,1例误诊为淋巴结,另1例误诊为腺淋巴瘤。超声对本病的诊断率为91.30%,误诊率为8.70%。结论高频彩超对腮腺及颌下腺混合瘤的诊断有重要价值,应结合病史,肿块发生部位及回声表现、血流分布情况。对我院经手术病理证实的腮腺及颌下腺混合瘤进行二维彩超回顾性分析。

Abstract purpose to exceed the evaluation value of high frequency colour ultrasonography on diagnosis of mixed tumor located in Parotid and submandibular gland Methods 23 cases confirmed by surgery pathology of mixed tumor of parotid and submandibular gland were retrospectively analyzed.
Results: 13 cases occurred in the parotid gland,9 cases occurred in submandibular gland,1 case of multiple,there are both in parotid and submandibular gland.There are 2 cases misdiagnosed.1 case with mixed tumor was misdiagnosed as lymph nodes,and 1 case was misdiagnosed as other glands lymphoma.Ultrasonography in the diagnosis of this disease was 91.30%,the misdiagnosis rate was 8.70%.

Conclusion: high frequency colour to exceed to the diagnosis of parotid and submandibular gland mixed tumor has important value,but for some special bump still must be carefully distinguished,according to tumor location and performance of the echo,blood flow distribution and so on.Isolates were confirmed by surgery pathology of parotid and submandibular gland to two-dimensional colour to exceed mixed tumor were retrospectively analyzed.

1 資料与方法
1.1 临床资料 随机选取2013年2月至2014年1月经手术病理证实的腮腺及颌下腺混合瘤患者23例,所有患者均经过高频超声检查,并外科手术切除。最后证实患者23例,女15例,男8例,年龄28~80(平均52.96岁),13例发生于腮腺,9例发生于颌下腺,1例为多发性,所有患者在年龄性别肿块大小及病情严重程度方面均无显著差异,不具可比性(P>0.05)。
1.2 检查方法 采用Alocka7高频彩色超声诊断仪,探头频率6~12MHz。为保证检查准确性,所有患者均应按照要求仰卧位或侧卧位,头转向健侧,颈伸长,使头颈充分伸展,使被检区充分暴露,先用二维超声对腮腺、颌下腺做纵、横切多个方位进行扫查。观察肿块的位置、大小、形态、边缘、内部回声等,并与健侧对比,然后用彩色多普勒进行血流的显示,通过频谱多普勒测量血流速度及阻力指数。

2.1 腮腺及颌下腺混合瘤的超声检查及超声诊断符合率
经超声检查显示,其中13例发生在腮腺,9例发生在颌下腺,1例为多发性,腮腺及颌下腺均有。其中有2例误诊,1例混合瘤误诊为淋巴结,另1例误诊为腺淋巴瘤;且有1例为癌在混合瘤中;23例中有4例为复发性。超声对本病的诊断率为91.30%,误诊率为8.70%。肿瘤诊断率与病理比较见附表1,混合瘤声像图特点见表2,混合瘤大小及血流特点见表3。
2.2 组织形态及血流分布检查结果
根据血流分布形态及血流强度分级,作出以下评估指标[1]:①0级:肿块内部未见血流信号(无血流信号);②Ⅰ级:偶尔见一点血流信号或内部有一条血管通过病灶(少量血流信号);③Ⅱ级:肿块内见四点血流信号或二条血管通过(病灶较丰富血流信号);④Ⅲ级:肿块内见七点以上血流信号(丰富血流信号);⑤Ⅳ级:极易见到七点以上大量血流信号或血管(极丰富血流信号)。, 百拇医药(陈桂芹 陈修娟 林梓桐 尤佳 王铁梅)
