3D打印个性化鼻模在单侧唇裂术后继发鼻畸形矫正中的应用

Application of 3D printing personalized nasal stent in the correction of secondary nasal deformities after unilateral cleft lip surgery

目的探讨个性化鼻模在单侧唇裂术后继发鼻畸形矫正中的应用效果。方法选取2020年9月至2021年9月单侧唇裂术后继发鼻畸形患者40例,随机分为研究组和对照组,每组20例,术后分别佩戴个性化鼻模和成品鼻模。术后1周和术后6个月时分别测量健、患侧鼻孔的宽度和高度,比较两组术后6个月健侧鼻孔和患侧鼻孔的变化情况。结果术后6个月,研究组患侧鼻孔高度变化和宽度变化均小于对照组,差异有统计学意义(P<0.05)。术后6个月,比较两组健侧鼻孔的高度变化和宽度变化,差异均无统计学意义(P>0.05)。研究组术后效果评分高于对照组,差异有统计学意义(P<0.05)。结论个性化鼻模对鼻畸形整复术后鼻孔的支撑,鼻小柱偏斜、鼻尖形态和鼻基底的改善都有显著效果,值得临床推广使用。

Objective To investigate the effect of personalized nasal stent in the correction of secondary nasal deformities after unilateral cleft lip surgery.Methods Forty patients with secondary nasal deformities after unilateral cleft lip surgery from September 2020 to September 2021 were randomly divided into study group and control group,with 20 patients in each group.After surgery,a personalized nasal stent and a finished nasal stent were used respectively.The width and height of the healthy side and the affected side were measured 6 months and 1 week after operation,and the changes of the healthy side and the affected side were compared between the two groups 6 months after operation.Results Six months after surgery,the height and width changes of the affected side of the nostril in the study group were smaller than those in the control group,with statistical significance(P<0.05).Six months after surgery,there was no significant difference in height and width changes of the healthy side nostril between the two groups(P>0.05).The postoperative effect score of the study group was higher than that of the control group,the difference was statistically significant(P<0.05).Conclusion Personalized nasal stent has significant effects on the support of nostrils,the improvement of the nasal columella deviation,the nasal tip shape and the nasal base after nasal deformity reconstruction,which is worthy of clinical application.
