摘要
目的 研究扩张囊外露并发症的有效预防技术。方法 回顾分析 15 72个扩张部位中的扩张囊外露发生规律 ,提出扩张囊外露综合防止技术 ,并对 2 87个扩张区进行临床验证。结果 15 72个扩张部位中 ,扩张囊外露并发症发生率为 6 .2 3 % ,并分为 5型。采用综合预防技术后扩张囊外露并发症发生率降到1.74%。结论 利用综合方法可有效防止扩张囊外露并发症的发生。
Objective To study the effective techniques for prevention of complications of expander exposure. Methods The behavior of 98 expander exposure from 1572 expansive places was analyzed retrospectively. Comprehensive techniques for expander exposure control were tested in 287 expansive places. Results 98 expander exposure in retrospective cases were divided into five types and the exposure rate was 6.23 %. With comprehensive control techniques, the expander exposure rate was decreased to 1.74 % . Conclusion The comprehensive techniques are reliable in expander exposure complications prevention.
