Craniomaxillofacial (CMF) trauma surgery is difficult because of its unique architecture and vast range of injuries in the head and neck area. This study sought to determine the potential of employing preoperative three-dimensional (3D)-printed models to improve frontal fracture healing outcomes. This prospective cohort clinical trial involved 20 patients who were surgically fitted and had a frontal bone fracture, as evidenced by computed tomography. The patients were separated into two groups: Group A: patients with frontal bone trauma reduced using 3D printing; and Group B: patients with frontal bone trauma reduced without 3D printing. Compared to Group B, Group A had a considerably shorter operational time ( < 0.001). The esthetic results, complications, and functional outcomes were not significantly different between the two groups. All patients in Groups A and B underwent accurate radiographic evaluations (correct placement of the titanium mesh). 3D printing in preoperative planning improves frontal fracture repair with respect to operative length but does not reduce intraoperative blood loss or improve postoperative function compared with normal management.
颅颌面（CMF）创伤手术具有挑战性，因其独特的结构以及头颈部区域广泛的损伤类型。本研究旨在探讨术前使用三维（3D）打印模型改善额骨骨折愈合效果的可能性。
这项前瞻性队列临床试验纳入了20例经计算机断层扫描证实存在额骨骨折且接受了手术整复的患者。患者被分为两组：A组：使用3D打印技术进行额骨创伤整复的患者；B组：未使用3D打印技术进行额骨创伤整复的患者。
与B组相比，A组的手术时间显著缩短（<0.001）。两组之间的美学效果、并发症及功能结局无显著差异。A组和B组的所有患者均接受了精确的影像学评估（钛网放置正确）。
术前规划中使用3D打印技术可缩短额骨骨折修复手术的时长，但与常规治疗相比，并未减少术中出血量或改善术后功能。
