目的：应用CBCT三维重建测量技术评价唇腭裂患者二期鼻整形术前术后鼻外形的改变。方法：对20例正常成年人及20例单侧唇腭裂二期鼻整形术前及术后6个月拍摄CBCT（cone-beam computed tomography），获取三维面部影像数据，以Dicom的格式转移到simplant11.04软件程序，建立面部三维图像，对鼻及周围结构定点，并进行线距及角度测量。测量结果采用SPSS13.0系统软件包对数据进行配对t检验。结果：对21个标记点共14项测量项目进行测量标记（放进方法里面），并对其中5项指标进行了患、健侧比较（放进方法，列出重要指标）。术前单侧唇腭裂患者双侧鼻翼发育程度不一致，患侧较健侧发育不全：鼻尖位置偏健侧，鼻尖下点到鼻翼外侧缘点的距离患侧大于健侧；鼻中线偏斜；鼻面角、鼻唇角小于正常人，鼻额角大于正常人；患侧鼻孔宽度大于健侧；鼻小柱偏向健侧。术后：患、健侧鼻孔宽度接近相等。结论：应用CBCT三维重建测量技术能精确测量外鼻相关数据，并可以明确外鼻的畸形程度，患、健侧组织不对称程度及评价手术疗效。

Objective To evaluate the before and after period change of patients with cleft lip and palate nose rhinoplasty with the application of CBCT 3D reconstruction measurement technique. Methods Taking CBCT before and after surgery in 20 cases of normal adults and 20 patients with unilateral cleft lip and palate nose rhinoplasty of two period for 6 months(cone-beam computed tomography),to obtain the 3D facial image data,in the form of Dicom which can transferred to the Simplant 11.04 software,then build the face of three-dimensional image,structure the fixed-point of nose and the surrounding,meanwhile measure the line distance and angle.Using SPSS 13 software package for data to measure the results in order to paire t-test. Results Measure 14 measured markers which included of 21 markers(put into method),and compared with 5 indicators which were the healthy side,(into the method,list the important index).Compared to healthy side hypoplasia, preoperative patients with unilateral cleft lip cleft palate alae nasi was not consistent:the tip of the nose position partial contralateral,the distance to nose point of alar lateral margin was larger than the contralateral nasal midline deviation;nasal facial angle and nasolabial angle was smaller than normal people.The amount of nasal angle was greater than normal,ipsilateral nostril width was larger than the contralateral nasal columella that toward the healthy side.Postoperative contralateral nostril:patient, width nearly equal. Conclusion The application of CBCT measurement technology of 3D reconstruction can accurately measure the external nasal related data, and can clear the nasal deformity patients, operation,curative effect and evaluation of the contralateral tissue asymmetry.
