This study aimed to assess ultrasonography (US) features of normal submandibular parenchyma (NSP) and incidental diffuse submandibular disease (DSD). From January 2013 to December 2017, 39 patients underwent preoperative US of the submandibular gland before submandibular surgery in our hospital. Among them, 9 were excluded because of inadequate histopathologic data (n = 7) or poor US image quality (n = 2). The US features of the resected submandibular glands were retrospectively investigated by a single radiologist, blinded to clinicoserological information and the histopathologic result, using a picture archiving and communication system. Histopathologic analysis of the submandibular gland was retrospectively performed by a single pathologist. After histopathologic analysis, 11 of the 30 patients were classified as DSD and 19 as NSP. Of the individual US features, only parenchymal echotexture exhibited a statistically significant difference between NSP and DSD (P < 0.0001), whereas the other US features showed no significant differences (P > 0.05). There was no significant relationship between diffuse fibrosis and glandular size (P = 0.310) or the other US features (P = 1.000). In conclusion, US may be helpful for differentiating incidental DSD from NSP.
本研究旨在评估正常下颌下腺实质（NSP）及偶然发现的弥漫性下颌下腺疾病（DSD）的超声（US）特征。2013年1月至2017年12月，我院39例患者在接受下颌下腺手术前进行了下颌下腺术前超声检查。其中，7例因组织病理学数据不充分、2例因超声图像质量差而被排除。由一名对临床血清学信息和组织病理学结果不知情的放射科医生，使用图像存档和通信系统对切除的下颌下腺的超声特征进行回顾性研究。由一名病理科医生对下颌下腺进行回顾性组织病理学分析。组织病理学分析后，30例患者中11例被归类为DSD，19例为NSP。在各项超声特征中，仅实质回声纹理在NSP和DSD之间存在统计学显著差异（P<0.0001），而其他超声特征无显著差异（P>0.05）。弥漫性纤维化与腺体大小（P=0.310）或其他超声特征（P=1.000）之间无显著相关性。总之，超声可能有助于鉴别偶然发现的DSD与NSP。
