Standard wound closure techniques are prone to complication in the presence of tension.
To show that deep plane fixation (DPF), a surgical modality based on limited undermining and strategic placement of DPF sutures, affects tension-reduced closure in wounds that would otherwise require skin grafts/flaps or tissue expansion.
The study is based on an analysis of over 2000 scalp operations.
Two groupings of identical sagittal scalp reductions were done. DPF was used in one and not the other. In the series with DPF, reduced tension closure was consistently possible, as was significantly increased excision, relative to the series without DPF.
DPF narrows the wound base and channels tension forces from superficial to deep and/or nonundermined tissues (where they harmlessly dissipate). This allows relatively increased tissue excision and tension-reduced closure.
在存在张力的情况下,标准伤口闭合技术容易出现并发症。
证明深部平面固定(DPF),一种基于有限潜行分离和DPF缝线的策略性放置的手术方式,对那些否则需要植皮/皮瓣或组织扩张的伤口,能实现张力降低的闭合。
该研究基于对2000多例头皮手术的分析。
进行了两组相同的矢状位头皮缩减手术。一组使用DPF,另一组未使用。在使用DPF的系列手术中,相对于未使用DPF的系列手术,始终能够实现张力降低的闭合,同时切除范围也显著增加。
DPF可缩小伤口基底,并将张力从浅表引导至深部和/或未潜行分离的组织(在这些组织中张力无害地消散)。这使得组织切除相对增加,且能实现张力降低的闭合。
