唇腭裂修复术后出现的面中份生长发育不足是当今临床上一个急待解决的问题,然而对一些基础研究却进行得很少。本文作者对8到22周出生前的唇腭裂(9例)和正常发育(20例)胎儿进行了组织学研究。在上唇鼻中隔前颌区标本上作冠状切片(20μm),以苏木精和嗜伊红染色后进行组织学观察分析,发现上唇鼻中隔前颌区对面中份生长发育起着重要作用,唇腭裂和正常胎儿之上唇鼻中隔前颌区的生长发育存在着明显差异。8周正常胎儿,鼻中隔和鼻翼外侧软骨发育完好并为疏松的间质、神经和血管围绕,鼻中隔下区形如半球,紧靠鼻中隔下份是U-
In the face of cleft lip and palate repair appear in the growth of under-growth is an urgent clinical problem, but for some basic research has been carried out very little. The authors performed a histological study of 8 to 22 weeks before birth in cleft lip and palate (n = 9) and normal (20) fetuses. Coronal section of upper lip and nasal septum in the maxillary area was made into coronal sections (20μm). Histopathological examination was performed with hematoxylin and eosin. The results showed that the upper lip and nasal septum of the maxillary area played an important role in the growth of Zhongzhong, There is a clear difference in the growth and development of the labial and maxillary prefrontal lip between the normal fetus and fetus. 8 weeks normal fetus, nasal septum and lateral alar cartilage well-developed and loose interstitial, nerve and blood vessels around the nasal septum shaped like a hemisphere, next to the nasal septum is U-
