To confirm whether or not the alar cartilage of the unilateral cleft lip nose is primarily hypoplastic as compared with the noncleft side, 35 unilateral cleft lip nasal patients who had no previous nasal surgery underwent direct measurement of the lateral crus of alar cartilage on both sides during their nasal tip plasties. Both lower lateral cartilages were dissected freely, and the thickness was measured at the intercrural, middle, and distal portions. The width was measured at the widest portion, and the length was measured from the intercrural point to the distal end. Two-mm-punch biopsies were obtained from each cartilage for histologic study. The lateral crus of the cleft side was no smaller than that of the noncleft side. Histologically, no difference was ascertained. In conclusion, we think the lateral crus of the alar cartilage of the cleft side is not hypoplastic. Therefore, external factors such as soft-tissue defect or external abnormal vector force are more attributable than intrinsic factors to the development of cleft lip nasal deformity.
为了确定单侧唇裂鼻的鼻翼软骨与非裂侧相比是否存在原发性发育不全，35例未曾接受过鼻部手术的单侧唇裂鼻患者在鼻尖整形术中对两侧鼻翼软骨外侧脚进行了直接测量。双侧下外侧软骨均被充分游离，在脚间、中部和远端测量其厚度。在最宽处测量宽度，从脚间点至远端测量长度。从每个软骨获取2毫米的组织块进行组织学研究。裂侧的外侧脚并不小于非裂侧。组织学上，未发现差异。总之，我们认为裂侧鼻翼软骨外侧脚并无发育不全。因此，唇裂鼻畸形的发生更多归因于软组织缺损或外部异常向量力等外部因素，而非内在因素。
