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.
■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。
