BACKGROUND
Thread rhinoplasty can trigger a reaction to thread material, which is a foreign body. We compared clinical features induced by absorbable and non-absorbable threads following thread rhinoplasty.
CASE SUMMARY
Two patients who underwent different thread materials showed different clinical courses and different Hounsfield unit (HU) values in computed tomography. Patients with absorbable thread showed high HU values similar to a metallic material, and the HU value of inflammation was similar to vascular tissues with a lot of water (250). In the intraoperative field, absorbable thread materials and micro-abscesses were observed. In contrast, in the case of a non-absorbable thread, an object presumed to be thread was seen on the computed tomography (CT), and the HU value of inflammatory tissues was less than 100. In both patients, post-operative HU decreased to less than 100 and the clinical course improved. In both cases, histopathologic findings revealed foreign body granuloma associated with inflammation.
CONCLUSION
Absorbable threads were more aggressive and are more easily detected on CT.
背景
线雕隆鼻术可引发对作为异物的线材料的反应。我们比较了线雕隆鼻术后可吸收线和不可吸收线引起的临床特征。
病例总结
两名接受不同线材料的患者在计算机断层扫描中表现出不同的临床过程和不同的亨氏单位（HU）值。使用可吸收线的患者显示出与金属材料相似的高HU值，炎症的HU值与含有大量水分的血管组织相似（250）。在手术视野中，观察到可吸收线材料和微脓肿。相比之下，在不可吸收线的病例中，计算机断层扫描（CT）上可见疑似线的物体，炎症组织的HU值小于100。两名患者术后HU均降至小于100，临床过程改善。在这两个病例中，组织病理学检查结果均显示伴有炎症的异物肉芽肿。
结论
可吸收线更具侵袭性，在CT上更容易检测到。
