■鼻中隔粘膜-软骨膜瓣在瓣抬高过程中会撕裂。在愈合过程中,对撕裂伤进行适当的修复对于防止间隔穿孔的发展至关重要。我们旨在确定用于修复鼻中隔粘膜-软骨膜瓣撕裂的上缝合类型和缝合距离。
■该研究使用了由羊头制备的128个鼻中隔粘膜-软骨膜瓣。使用四种缝合材料之一(4-0/5-0Polyglactin910,4-0/5-0聚二恶烷酮)用两根间断的缝合线缝合粘膜-软骨膜瓣上的实验性撕裂伤,并在缝合线之间留出5毫米或10毫米的距离。测量每种缝合材料和使用的缝合距离的最大组织保持强度(HSmax)。
■当在缝合材料和缝合距离方面比较各组时,Polyglactin910缝合(p<0.001)和10mm缝合距离(p=0.008)的平均HSmax值较高,分别。直径为4-0和5-0的缝合线的平均HSmax值之间没有统计学上的显着差异(p=0.057)。
■在修复鼻中隔粘膜裂伤时,两个相邻缝线之间具有10mm空间的Polyglactin910缝线材料可能比其他缝线材料更耐用。
UNASSIGNED: Septal mucosal-perichondrial flaps can be lacerated during the elevation of the flaps. Appropriate repair of the lacerations is essential to prevent the development of septal perforation during the healing process. We aimed to determine the superior suture type and suture distance to use in repairing the lacerations of nasal septal mucosal-perichondrial flaps.
UNASSIGNED: The study used 128 nasal septal mucosal-perichondrial flaps prepared from sheep heads. Experimentally induced lacerations on the mucosal-perichondrial flaps were sutured with two interrupted sutures using one of four suture materials (4-0/5-0 Polyglactin 910, 4-0/5-0 Polydioxanone) and leaving either 5 mm or 10 mm distance between the sutures. Maximum tissue holding strength (HSmax) was measured for each suture material and suture distance used.
UNASSIGNED: Mean HSmax values were higher for Polyglactin 910 sutures (p<0.001) and 10 mm suture distance (p=0.008) when the groups were compared in terms of suture material and suture distance, respectively. There was no statistically significant difference between the mean HSmax values of sutures with 4-0 and 5-0 diameters (p=0.057).
UNASSIGNED: Polyglactin 910 suture material with 10 mm space between two adjacent sutures may be more durable than the other suture materials when repairing nasal septal mucosal lacerations.
