数字成型钛网颅骨修补后的皮下积液

背景：数字成型钛网修补颅骨缺损后常发生皮下积液等不良反应，影响治疗效果。 目的：探讨数字成型钛网修补颅骨后发生皮下积液的原因及相应的防治措施。 方法：回顾性分析19例行数字成型钛网修补颅骨后皮下积液患者的临床资料和处理方式，总结修补后并发症发生原因，探讨有效的防治方法。 结果与结论：19例修补中硬膜破损5例，材料刺激4例，下床过早3例，拔管过早3例，术后修补时间过长3例，过度使用电刀1例，考虑皮下积液的发生与上述因素相关，硬膜破损与材料刺激为术后皮下积液的主要原因，出现皮下积液后均给予松解弹力绷带，待积液达到皮下后行穿刺抽吸，严格卧床等积极处理后全部治愈。引起皮下积液的原因可能会单发或混合出现，但上述仅仅是部分原因，有文献显示未中心悬吊、止血不彻底、术前骨窗过于塌陷等均是发生皮下积液的原因。中国组织工程研究杂志出版内容重点：生物材料；骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性；组织工程全文链接：

Subcutaneous effusion after digital shaping titanium mesh cranioplasty

BACKGROUND: Subcutaneous effusion often occurs after digital shaping titanium mesh cranioplasty, and affects therapeutic effects.  OBJECTIVE: To explore the causes and corresponding prevention measures of subcutaneous effusion after digital shaping titanium mesh cranioplasty.  METHODS:We retrospectively analyzed the clinical data and treatment methods of 19 cases of subcutaneous effusion after digital shaping titanium mesh cranioplasty, summarized the postoperative complications and explored the effective methods for prevention and treatment of subcutaneous effusion. RESULTS AND CONCLUSION: After active treatment, five cases of dural breakage, four cases of foreign body stimulation, three cases of getting out of bed early, three cases of early extubation, three cases of long-time operation repair, and one case of excessive use of electric knife were all cured. Dural breakage and foreign body stimulation is considered as the main causes of postoperative effusion. Patients with subcutaneous effusion were given releasing elastic bandage, aspiration, and strict bed rest. After these active treatments, patients were all cured. Subcutaneous effusion may result from single or mixed factors. The above-mentioned causes are only a part. Non-central suspension, incomplete hemostasis, and preoperative excessive collapse of the bone window are all reported to be the reasons for the occurrence of subcutaneous effusion.
