Preoperative diagnosis of parotid tumors plays a crucial role in selecting and planning the surgical treatment. Ultrasound (US) with its modern techniques can contribute to the differential diagnosis of parotid tumors. This paper aims to achieve a comprehensive review of the ultrasound techniques used in the differential diagnosis of parotid tumors, based on the latest literature data. Considering that most parotid gland tumors are located in the superficial lobe, US is frequently the first imaging technique used for the diagnosis of parotid tumors. Sonoelastography can provide additional data on the elasticity of parotid tumors, but there is an overlap between malignant and benign parotid tumors parameters. Contrast-enhanced ultrasound adds value to conventional ultrasound and allows a more complete characterization of parotid tumors. Many authors have reported promising results using contrast-enhanced ultrasound in the differential diagnosis of parotid tumors. Multiparametric ultrasound with a careful and systematic approach usually allows an accurate differential diagnosis of parotid tumors.
术前诊断在选择和计划腮腺肿瘤的治疗中起着至关重要的作用。超声（US）及其现代技术有助于腮腺肿瘤的鉴别诊断。本文旨在根据最新的文献资料，对超声技术在腮腺肿瘤鉴别诊断中的应用进行全面回顾。考虑到大多数腮腺肿瘤位于浅叶，US 通常是诊断腮腺肿瘤的首选影像学方法。声触诊组织量化技术可以提供关于腮腺肿瘤弹性的额外数据，但恶性和良性腮腺肿瘤的参数之间存在重叠。超声造影在常规超声的基础上增加了价值，可以更全面地描述腮腺肿瘤。许多作者已经报道了在腮腺肿瘤的鉴别诊断中使用超声造影的有前景的结果。多参数超声采用仔细和系统的方法通常可以对腮腺肿瘤进行准确的鉴别诊断。
