Abstract:

Objective: To assess the application value of color doppler ultrasonography in the detection and location of fishbones in cervicofacial region. Methods: The ultrasonographic features and clinical data of 57 cases of fish bones in cervicofacial region confirmed by surgical operation were retrospectively analyzed. All cases were divided into three age groups (Group A: less than 40-year-old, Group B: 40 to 80-year-old, and Group C: more than 80-year-old). The composition ratios of gender, age, and fishbones migration sites in each group were compared. The correlations between the maximum diameter of the ultrasound imaging clump and fishbone length and the lock time were analyzed. The diagnostic value of ultrasonography in the migration of fishbone in cervicofacial region was summarized, and the characteristics of ultrasonograph in the migration of fishbone were analyzed. Results: The results of the composition ratio difference of gender in each group showed that the proportion of males was significantly higher than that of females. The proportion of cases in the age group B was significantly higher than that of the other two age groups. In the age group less than 40-year-old, the proportion of fishbone migrating to the neck was higher, and in the age group 40 to 80-year-old, the proportion of fishbone migrating to the submandibular and submental regions was higher, and in the age group more than 80-year-old, the proportion of fishbone migrating to the submandibular was higher, There was a positive correlation between the maximum diameter of the lump and the length of the fishbone(Pearson correlation coefficient r=0.574, P<0.001) and the lock time (Pearson correlation coefficient r=0.861, P<0.001). The multi-slice spiral CT scan reconstruction or short-term ultrasound follow-up should be performed at the same time. coincidence rate of ultrasonic diagnosis of fish bones in the face and neck was 98.2%. Ultrasonographic images were characterized by streak-like hyperechoic with enhanced echogenic in surrounding soft tissue and streak-like hypoechoic in surrounding organs in poorly defined hypoechoic or mixed echogenic clusters. Conclusion: Ultrasonography is the preferred imaging method in assisted to locate the migration of fishbone in cervicofacial region. And medical history and clinical data should be combined, when the examination results are negative.

摘要：

目的： 探讨彩色多普勒超声在面颈部鱼刺迁移中的应用价值。方法： 回顾性分析我院57例经外科手术证实为鱼刺的面颈部异物的超声声像图特点及临床资料。将病例分为<40岁、40~80岁、>80岁3组年龄段，比较各组性别、年龄和鱼刺迁移部位的构成比差异。分析超声声像团块的最大直径与鱼刺长度、卡顿时间的相关性。总结超声在面颈部鱼刺迁移中的诊断价值，分析鱼刺迁移部位的超声表现特点。结果： 各组性别的构成比差异结果显示，男性比例明显高于女性，40~80岁年龄组病例数的比例明显高于其他2组。<40岁年龄组中，鱼刺迁移至颈部的比例较高；40~80岁组鱼刺迁移至颌下和颏下部位的比例较高；>80岁组鱼刺迁移至颌下比例较高。团块的最大直径与鱼刺的长度存在正相关，Pearson相关系数r=0.574，P<0.001；团块的最大直径与鱼刺卡顿时间存在正相关，Pearson相关系数r=0.861，P<0.001。超声诊断面颈部鱼刺的符合率为98.2%，超声声像以边界不清的低回声或混合回声团，内见条状强回声伴有周边软组织回声增强及周边脏器内条状低回声为特点。结论： 超声是面颈部鱼刺迁移中首选的影像学检查方法，同时要结合病史及临床资料，检查结果阴性时应同时进行多层螺旋CT扫描重建或短期超声随访。
