腭裂患者鼻中隔偏曲的CBCT评价

Evaluation of nasal septum deviation in cleft palate patients using Cone-Beam Computed Tomography

目的：通过锥形束CT（CBCT）测量分析腭裂患者的鼻中隔偏曲状况.方法：选取59例腭裂患者的CBCT图像进行测量分析,探究不同腭裂类型与鼻中隔偏曲程度、偏曲位置的关系以及腭裂侧与鼻中隔偏曲侧的一致性,探究单侧完全性腭裂患者中,鼻中隔偏曲程度和偏曲位置的关系.结果：59例腭裂患者鼻中隔偏曲角度为1.41°～29.17°,相对偏曲度为6.5 ％～66.3 ％.完全性腭裂患者的鼻中隔偏曲程度较不完全性腭裂者严重：单侧完全性腭裂患者中,鼻中隔均凸向裂隙侧,高、中位偏曲患者的鼻中隔相对偏曲度大于低位偏曲患者.结论：CBCT作为一种实用有效的影像学检查手段,在对患者腭裂状况评价的同时,也可以准确地判断腭裂患者鼻中隔偏曲情况.

Objective：Cone-Beam Computed Tomography （CBCT） is used to investigate the condition of nasal septum deviation in cleft palate patients,and to analyze the relationship between cleft palate and nasal septum deviation.Method：Fifty-nine cleft palate patients were recruited in this study.With the CBCT imaging,two measure methods （deviation angle ＆relative deviation degree） were used to analyze the relationship between different patterns of cleft palate and the extent of deviation.We also investigated the consistency of the sides of cleft palate and nasal septum deviation.Among the unilateral complete cleft palate patients,the relationship between the extent and position of the deviation was analyzed as well.Result：The deviation angle of the 59 patients ranged from 1.41°to 29.17°,and the deviation degree from 6.5 ％ to 66.3 ％.The extent of deviation was more significant in patients with complete cleft palate than with incomplete cleft palate.Among unilateral complete cleft palate patients,the sides of deviation and cleft were consistent,and relative deviation degrees were more significant in those with upper and medium nasal septum deviation than with lower deviation.Conclusion：CBCT is an effective imaging examination,by which we are able to accurately evaluate the condition of cleft palate as well as the nasal septum deviation in those patients.
