Ultrasound is one of the main diagnostic techniques for parotid gland tumours. It is inexpensive, non-invasive and widely available. However, interpretation of the images is highly subjective and constitutes a major limitation. To overcome this problem, we developed a graphic diagram to provide a standardised template that can be used for more precise identification of the tumour localisation within the parenchyma of the parotid gland. This new diagram may be used to provide surgeons with an improved and more objective localisation of the tumour. The study included 237 patients who underwent surgery for parotid tumours. To obtain the precise spatial location of the tumours, three topographic coordinates of tumour location in the coronal, sagittal and transversal plane were marked preoperatively during sonography within the parenchyma of the parotid gland. The localisation identified ultrasonically was then compared to the postsurgical report: 197 (83 %) tumours were found within the superficial lobe of the parotid gland and 40 (17 %) within the deep lobe of the parotid gland. In 157 (66 %) cases, tumours were found within the lower pole of the parotid gland, and in 64 (27 %) at the level of earlobe and its insertion, 16 (7 %) tumours were located at the level of the tragus and above it. Based on the results obtained, a graphic diagram of parotid gland tumour locations was developed.
超声是腮腺肿瘤的主要诊断技术之一。它价格低廉、非侵入性且广泛可用。然而，图像的解释高度主观，这构成了主要的限制。为了克服这个问题，我们开发了一个图形图表，提供了一个标准化的模板，可以更精确地识别腮腺实质内肿瘤的定位。这个新的图表可以用来为外科医生提供更精确和客观的肿瘤定位。该研究纳入了 237 名因腮腺肿瘤接受手术的患者。为了获得肿瘤的确切空间位置，在腮腺实质的超声检查中，术前在冠状面、矢状面和横断面标记三个肿瘤位置的拓扑坐标。然后将超声识别的定位与术后报告进行比较：197 个（83%）肿瘤位于腮腺浅叶，40 个（17%）位于腮腺深叶。在 157 例（66%）中，肿瘤位于腮腺下极，64 例（27%）位于耳垂及其插入部位，16 例（7%）位于耳屏水平及其上方，16 例（7%）位于耳屏上方。基于所获得的结果，开发了一个腮腺肿瘤位置的图形图表。
