This text reviews the normal ultrasound (US) anatomy of the salivary glands along with tumoral, lithiasic, and inflammatory pathologies. For salivary gland tumors, US does have limitations (failure to visualize the entire parotid gland, relations with the nerve plexus, in-depth spread of large tumors, false-negative errors of malignancy for small encapsulated tumors). However, US is a simple technique allowing correct identification of the benign nature of a lesion in over 80% of the cases. For lesions under 3 cm in diameter, US is generally the only imaging technique used; for larger lesions, CT or MR is required. Sialolithiasis and inflammatory diseases are being documented by US more and more and the indications for sialography have strongly decreased.
本文回顾了唾液腺的正常超声（US）解剖结构以及肿瘤、结石和炎症性病变。对于唾液腺肿瘤，超声确实存在局限性（无法显示整个腮腺、与神经丛的关系、大肿瘤的深部扩散、小的包膜完整肿瘤的恶性假阴性错误）。然而，超声是一种简单的技术，在超过80%的病例中能够正确识别病变的良性性质。对于直径小于3厘米的病变，超声通常是唯一使用的成像技术；对于较大的病变，则需要CT或MR。超声越来越多地用于记录涎石病和炎症性疾病，而唾液造影的适应证已大幅减少。
