The closed reduction for zygomatic arch fracture relies on indirect techniques like auditory or tactile feedback intra-operatively and are confirmed post-operatively by radiographs. The aim of this study was to investigate the efficacy of USG-guided arch fracture reduction against conventional reduction techniques.
The patients were randomly allocated for this quasi-randomized controlled trial and study was double-blinded. The fracture reduction was done under USG guidance in test group (USG group). The primary outcome assessed was evaluation of post-operative SMV x-ray. The change in discontinuity pattern between the pre-operative and post-operative x-ray was used to assess the adequacy of reduction. Inter-group analysis was done to compare the outcomes of the test and control group. Secondary outcomes assessed were maximal inter-incisal mouth opening (MIO) and depression along the zygomatic arch.
Study comprised of 29 patients, amongst which 10 patients underwent fracture reduction under USG guidance, while 19 patients underwent reduction by conventional method. Fisher's exact test of post-operative SMV showed a significant difference (p 0.05) between USG group and control group, with the results favouring the USG-guided reduction.
USG-guided reduction of zygomatic arch fracture can lead to better fracture reduction in comparison to conventional method of closed zygomatic arch reduction.

颧弓骨折的闭合复位术中依赖听觉或触觉反馈等间接技术，并在术后通过X光片确认。本研究的目的是探讨超声引导下颧弓骨折复位相对于传统复位技术的疗效。
本准随机对照试验将患者随机分组，研究采用双盲法。试验组（超声引导组）在超声引导下进行骨折复位。评估的主要结果是术后SMV X光片。术前和术后X光片之间不连续模式的变化用于评估复位的充分性。进行组间分析以比较试验组和对照组的结果。评估的次要结果是最大切牙间开口度（MIO）和颧弓处的凹陷。
该研究纳入29例患者，其中10例在超声引导下进行骨折复位，19例采用传统方法复位。术后SMV的Fisher精确检验显示超声引导组和对照组之间存在显著差异（p<0.05），结果支持超声引导下的复位。
与传统的颧弓闭合复位方法相比，超声引导下的颧弓骨折复位可实现更好的骨折复位。
