单侧唇腭裂外鼻软骨的外科解剖

Anatomy of the nasal cartilages of the unilateral lip and palate cleft nose

为探讨单侧唇腭裂外鼻软骨的解剖异常与鼻畸形的关系，对６例单侧唇腭裂死婴的外鼻部进行解剖，发现患侧鼻翼软骨及鼻中隔软骨发生了组织错位，与鼻畸形的产生有明确的对应关系；统计学处理结果显示，健、患侧鼻翼软骨的大小差异无显著性。说明组织错位是单侧唇腭裂鼻畸形的病理解剖的基础之一。

Noses of 6 stillborn infants with unilateral lip and complete palate cleft were dissected and analysed. The surgical dissection revealed that the lower lateral cartilages are asymmetrical on both sides, indicating displacement of the lower lateral cartilages and the cartilageous septum which deviates to the normal side. Paired T Test shown that there is no significant difference between two sides in length and width. The conclusion is that the nasal deformities of the lip and palate cleft are congenital and one of the major causal factors is the displacement of lower lateral cartilages and cartilageous septum in the cleft side.
