聚丙烯酰胺水凝胶注射隆鼻术后并发症的治疗

目的探讨聚丙烯酰胺水凝胶（polyacrylamidehydrogel，PAHG）注射隆鼻术后并发症产生的原因及相应的处理。方法分析和总结52例PAHG注射隆鼻术后并发症产生的原因，处理方法全部采用切开取出术。结果52例并发症中有感染、肉芽肿、皮肤破溃、外形不良、疼痛和严重的心理负担等。每例有1～4种并发症。根据不同情况采取相应的处理方法，并选取适当病例在取出PAHG的同期或兀期置人硅胶或膨体聚四氟乙烯假体，多数病例能取得较满意的效果，少数病例遗留后遗症和长久的心理负担或鼻部隐痛。结论PAHG注射隆鼻术后并发症种类多样，与PAHG的固有性质、鼻部软组织解剖特点有关。切开取出术能最大限度地清除注射物。是目前处理PAHG注射隆鼻术后并发症的较好方式。

Analysis and treatment of the complications caused by polyacrylamide hydrogel injection for augmentation rhinoplasty

Objective To analyze the causes and explore suitable treatments for the complica-tions induced by polyacrylamide hydrogel (PAHG) injection for augmentation rhinoplasty. Methods The causes of the complications of 52 cases who accepted PAHG injection for augmentation rhinoplas-ty were analyzed and summarized. All the patients were treated by surgical operations to remove the injected PAHG. Results The complications included infection, granuloma, skin ulceration, bad shape, pain and serious psychological stress. Each case had 1 to 4 complications. Satisfactory results were obtained after suitable treatments. Some cases had silicone or expanded polytetrafluoroethylene implant augmentation rhinoplasty at the same time or secondary to the PAHG removal. A few cases had sequelae and long time psychological stress or tend pain of nose. Conclusions The complications induced by PAHG injection for augmentation rhinoplasty are various, and may relate to the inherent character of PAHG and the anatomic features of the nasal soft tissue. Surgery can remove the PAHG as completely as possible, which is a better method to treat the complications of PAHG injection for augmentation rhinoplasty.
