摘　　要：目的:通过激光扫描建立0至12岁汉族儿童各年龄段正常鼻腔的三维重建模型,并揭示鼻腔随年龄发育的规律。方法:在全麻状态下对60例0至12岁的进行分组并制取鼻腔模型,用激光扫描仪扫描鼻腔形态,通过计算机工程软件进行模型重建。结果:此法可准确扫描鼻腔内部形态,并通过三维重合重建每组理想的鼻腔内部形态,并可以分析鼻腔随年龄增长的变化情况。结论:激光扫描三维分析方法是分析正常儿童鼻腔形态的理想方法,应用此模型可重建各个年龄段理想的鼻腔内部形态,并可量化分析正常儿童随生长发育而变化的鼻腔形态。Objectives： Based on laser - scanning technology, reconstruct a normal three - dimensional nasal cavity model for different age group and reveal the rule of nasal cavity development Methods： Nasal cavity＇s impressions of 60 children m＇e taken and detected by a laser scanner. Then , use a CAD/CAM/CAE software to perform 3D model reconstruction. Results： The method can precisely get the nasal cavity＇ s features and perform a ideal 3D reconsruction, by which we can analyze the development of nasal cavity. Conclusion： Laser scanning - 3D reconstruction technology is appropriate to study the morphology of nasal cavity.
