3D打印鼻骨复位器在骨折复位手术中主观疗效的临床分析

目的分析3D打印鼻骨复位器在鼻骨骨折复位手术中的应用价值及意义。方法将2016年1月~2018年7月收治的17例单侧鼻骨骨折或双侧鼻骨骨折对侧没有移位的鼻外伤患者作为研究对象，在鼻骨骨折复位手术前及术后1个月内分别行颌面部CT扫描，术中采用3D打印鼻骨复位器复位骨折，采用VAS评分对比手术前后患者对鼻外形的满意度和鼻腔通气情况比较。结果患者鼻外形满意度VAS评分从术前 (6.353±1.607）分降到术后(1.529±1.036）分，差异具有统计学意义(P<0.01); 鼻腔通气情况VAS评分从术前(2.912±2.315）分降到术后(0.882 4±0.322 2)分，差异具有统计学意义（P<0.01）。患者鼻外形主观满意度及鼻塞主观感觉均较术前有不同程度的改善。结论3D打印鼻骨复位器行鼻骨骨折复位操作简单且复位准确率高，可达到精准复位的目的。用3D打印鼻骨骨折复位器行鼻骨骨折复位术是可行且有效的。

Clinical subjective efficacy study on application of 3D printing nasal bone reduction device in nasal bone reduction

ObjectiveTo investigate the application value and significance of three dimensional (3D) printing nasal bone reduction device in nasal bone reduction.Methods17 patients suffering from unilateral nasal bone fracture or bilateral fracture without contralateral dislocation treated in our hospital between Jan. 2016 and July 2018 were enrolled in our study. Maxillofacial computed tomography (CT) scans were performed preoperatively and one month after operation in all patients. Nasal bone reduction was performed using individualized 3D printing nasal bone reduction device. The preoperative and postoperative visual analogue scale (VAS) scores of nasal contour satisfaction as well as nasal ventilation were recorded and compared for each one.ResultsThe mean VAS score of nasal contour satisfaction got decreased from the preoperative (6.353±1.607) to the postoperative (1.529±1.036), and the difference was statistically significant (P<0.01). Meanwhile, the mean VAS score of nasal ventilation was decreased from the preoperative (2.912±2.315) to the postoperative (0.882 4±0.322 2), and the difference was also statistically significant (P<0.01). After operation, the subjective satisfaction on nasal contour and ventilation got improved in different degree in all the patients.ConclusionsNasal bone reduction by using 3D printing nasal bone reduction device is simple to operate and produces highly accurate restoration. This new method can help the surgeons to perform the nasal bone reduction effectively and accurately.
