摘要探讨游离组织瓣在口腔颌面部创伤性组织缺损重建中的应用.方法回顾北京大学口腔医学院·口腔医院口腔颌面外科1999至2007年应用游离组织瓣重建创伤性组织缺损病例20例,分析受伤原因、缺损情况、游离组织瓣类型、手术并发症和术后功能恢复情况.结果 20例合并大型口腔颌面部软硬组织缺损患者中,单纯软组织缺损8例,软硬组织复合缺损12例;15例为Ⅱ期手术,5例为同期手术或与骨折复位固定术同期完成.20块游离组织瓣应用于缺损修复,其中腓骨瓣11例、髂骨瓣1例、前臂皮瓣7例、肩胛皮瓣1例,全部皮瓣均移植成功,未出现皮瓣坏死.结论 游离组织瓣移植安全可靠,可以修复口腔颌面部创伤性软硬组织缺损.腓骨瓣和前臂皮瓣是最常用的游离组织瓣.早期应用游离组织瓣修复创伤性软硬组织缺损可有效避免局部瘢痕和组织变形移位,缩短治疗时间,提高治疗效果.

abstractsObjective To evaluate the application, indications and outcomes of free flaps for ora-maxollofacial traumatic defects reconstruction. Methods Twenty consecutive cases of ora-maxollofacial the traumatic defects reconstruction with free flaps were reviewed. All clinical data including causes of injuries, the type of defects, selection of free flaps, perioperative complications and the follow-up were analyzed. Results All the cases underwent free flap reconstruction for ora-maxollofacial traumatic defects: 8 cases with soft tissue defects, 12 cases with soft and hard tissue defects. Fifteen patients received two-stage operation and 5 patients underwent primary reconstruction at the time of debridement or fracture reduction. Twenty free flaps were applied for the reconstruction, 11 cases with fibula flap, 1 case with iliac crest free flap, 7 cases with radial forearm flap and 1 case with scapula flap. No flap failure occurred. The successful rate of free flaps transfer was 100%. Conclusions The free flaps transfer is reliable and can reconstruct the ora-maxollofacial traumatic soft and hard tissue defects. Fibula and radial forearm free flap are the most common used flaps. Early aggressive surgery with free flaps transfer for traumatic defects can prevent the scar contracture and tissue displace, which can shorten the treatment period and improve the final outcome.
