儿童的软骨性鼻中隔往往遭外伤或有先天性畸形。作者着眼于它在出生后面中部发育中的作用,用幼兔研究了中隔软骨对种种手术操作反应下的创口愈合。用新西兰雌白兔35只,经左鼻背暴露鼻中隔,作粘软骨膜下分离后切除中1/3约10mm宽的软骨,由于联锁应力的结果该缺口立即缩成约8mm宽,故将切出的软骨修窄后重新植回,然后将兔分为七组分别于术后1天、3天、1周、2周、4周、8周及20周取出鼻中隔并用10%甲醛固定,作连续切片及HE染色,进行三维图象重建供研究。结论是:①粘软骨膜分离不引起中隔软骨明显组织反应;②切缘的创口反应仅有一条约0.8mm深
Children's cartilaginous septum often suffered trauma or congenital malformations. The authors looked at the role of the septal cartilage in the development of the central midgut after birth and studied the healing of the septal cartilage in response to various surgical manipulations. Thirty-five female New Zealand white rabbits were exposed to the nasal septum through the left nape of the back and removed for about 1/3 of the cartilage in the middle of about 1/3 mm. After the gap was shortened to about 8 mm wide due to the interlocking stress, The cut cartilage was stenosed and replanted. The rabbits were then divided into seven groups. Nasal septums were removed at 1 day, 3 days, 1 week, 2 weeks, 4 weeks, 8 weeks and 20 weeks after surgery and fixed with 10% formaldehyde. For serial sections and HE staining, three-dimensional image reconstruction for research. The conclusion is: ① mucoperiosteal separation did not cause obvious serous cartilage tissue reaction; ② margin of the wound reaction is only about 0.8mm deep
