目的探讨经皮微创坚固内固定在颧上颌骨折治疗中的效果。方法选择颧上颌骨折患者133例,设经皮微创观察组70例,经典入路对照组63例。分别对二组患者的疗效行对比分析。结果 1周创口延迟愈合观察组3例,对照组9例,创口换药并治疗性应用抗菌药物5d后Ⅱ期愈合,χ2=4.039,P<0.05,差异有统计学意义。6个月后实现开口度>3cm者观察组67例,对照组53例,χ2=5.048,P<0.05,差异有统计学意义。CT扫描显示Ⅱ期骨愈合观察组2例,对照组9例,χ2=5.708,P<0.05,差异有统计学意义。显著瘢痕观察组3例,对照组62例且伴头皮毛发缺损,χ2=117.570,P<0.05,差异有统计学意义。术后需颌间牵引观察组11例,对照组9例,χ2=0.053,P>0.05,差异无统计学意义。结论经皮微创治疗颧上颌骨折具有瘢痕不明显、创口及骨愈合较好、开口功能恢复等优势,且咬合关系恢复理想,是颧上颌骨折的一种理想的治疗方法。
Objective To investigate the effect of minimally invasive percutaneous internal fixation in the treatment of zygomatic maxillary fractures. Methods 133 cases of zygomatic maxillary fractures were selected, 70 cases were treated by percutaneous minimally invasive observation and 63 cases were treated by classical approach. The two groups of patients were compared the efficacy of treatment. Results One week’s delayed wound healing was observed in 3 cases in the observation group and 9 cases in the control group. After wound dressing and therapeutic antibiotic treatment for 5 days, healed by χ2 = 4.039, P <0.05, the difference was statistically significant. Six months later, there were 67 cases in the observation group and 53 cases in the control group with open degree of> 3cm, with the mean of χ2 = 5.048, P <0.05. The difference was statistically significant. CT scan showed 2 cases of bone healing in the observation group and 9 cases in the control group (χ2 = 5.708, P <0.05), the difference was statistically significant. Significant scar observation group 3 cases, control group 62 cases with scalp hair defects, χ2 = 117.570, P <0.05, the difference was statistically significant. Eleven patients underwent intermaxillary traction in the observation group and 9 in the control group (χ2 = 0.053, P> 0.05). There was no significant difference between them. Conclusion Percutaneous minimally invasive treatment of zygomatic maxillary fractures with scar is not obvious, the wound and bone healing better, the opening function recovery and other advantages, and the ideal occlusal relationship recovery, is an ideal treatment for zygomatic maxillary fractures.
