OBJECTIVE
Purpose of this study to introduce a new minimal access technique for management of anterior mandible fracture with several advantages over conventional methods.
METHOD
Four cases of undisplaced anterior mandibular fracture were selected. Tension band was achieved either by arch bar fixation to mandible or placement of interdental wire followed by intermaxillary fixation. With a 1 cm vertical incision was placed adjacent to fractured line. Fractured segment was immobilized with lag screw with minimal stripping. All patients were followed for 6 months.
RESULTS
All four cases shown good stable segment after 6 months of post operative follow up. OPG revealed well placed lag screw and there were no surgical complications, for example parasthesia, scarring and odema.
CONCLUSION
Fixation of anterior mandible fracture using this technique can achieve good stability and appropriate compression. The technique is simple and easily performed, reducing the surgical time, reduce the chances of infection due to less exposure and promote the healing process by producing stress in the fracture lines.
目的
本研究旨在介绍一种治疗下颌骨前部骨折的新型微创技术，该技术相较于传统方法具有多项优势。
方法
选取4例无移位的下颌骨前部骨折病例。通过将牙弓夹板固定于下颌骨或放置牙间金属丝并随后进行颌间固定来实现张力带。在骨折线旁作一个1厘米的垂直切口。用拉力螺钉固定骨折段，剥离范围最小。所有患者均随访6个月。
结果
术后6个月的随访显示，所有4例患者的骨折段均稳定良好。全景片显示拉力螺钉位置良好，且无手术并发症，如感觉异常、瘢痕形成和水肿。
结论
使用该技术固定下颌骨前部骨折可实现良好的稳定性和适当的加压。该技术操作简单，可减少手术时间，减少暴露导致的感染机会，并通过在骨折线处产生应力促进愈合过程。
