3D测量辅助个性化全鼻再造

3D measurement assisted personalized full nose reconstruction

目的通过3D测量正常人外鼻建立数据库为鼻缺损患者定制个性化外鼻,辅助术者进行全鼻再造手术,进而进行术后评估。方法 3D扫描受试者面部,测量鼻部相关指标建立数据库,术者参考正常人鼻部数据库为17例鼻缺损患者定制个性化外鼻,辅助其进行全鼻再造手术,并采用独立样本t检验进行数据统计,评估手术预期效果。结果右根翼距、左根翼距、鼻长、鼻基底宽、鼻宽、右侧垂直平分鼻唇线、左侧垂直平分鼻唇线、鼻高、内眦间距、面宽、口裂宽、面高、鼻面宽指数、鼻口宽指数、眶间-鼻宽指数、鼻面高指数等测量计算项目术后实际数据与术前个性化定制数据相比差异均无统计学意义(P>0.05),而鼻深术后实际数据与术前个性化定制数据相比差异有统计学意义(P <0.05)。结论分析表明外鼻术后实际数据与术前个性化定制数据差异无统计学意义。3D测量正常人外鼻建立数据库为鼻缺损患者定制个性化外鼻,可辅助术者进行全鼻再造手术,提高可预见性,使手术更为精准;还可进行术后评估,比较术前与术后预期效果。

Objective A database of normal people′s external nose was established through 3D measurement. This database was used to customize the external nose for patients with nasal defects and to assist the operator to carry out the whole nose reconstruction surgery,so as to carry out the postoperative evaluation. Methods 3D scanning of the subject′s face,measurement of relevant indexes of the nose and establishment of a database,the operator used normal nose database to customize the customized external nose for 17 patients with nasal defects,assisted them in the whole nose reconstruction surgery,and used independent sample t test for data statistics to evaluate the expected effect of surgery. Results There was no statistically significant differences between the postoperative actual data and the preoperative personalized data(P > 0.05)in right root wing distance, left root wing distance,nose length,nasal base width,nose width,right side vertical bisect nasal line,left side vertical bisect nasal line,nose height,medial malleolus spacing,face width,mouth split width,facial height,nasal width index,nasal width index,intercondylar-nasal width index and nasal high index. The actual data of nasal deep was statistically different from preoperative personalized data (P < 0.05). Conclusions Analysis showed no significant difference between the actual data nasal surgery and preoperative customization data. 3D measurement of normal human external nasal establishment database to customize the external nose for patients with nasal defects, can assist the surgeon to perform total nasal reconstruction surgery and improve predictability and make surgery more precise. Postoperative assessments can also be performed to compare preoperative and postoperative outcomes.
