医用胶和钛板钛钉固定兔上颌窦游离骨折片的对比研究

目的比较医用胶和钛板钛钉固定兔上颌窦游离骨折片的骨愈合状况,以期为临床应用提供依据。方法取兔8只,随机分为两组。实验组4例采用医用胶固定上颌窦游离骨折片;对照组4例采用钛板钛钉固定上颌窦游离骨折片。两组均人造成约1.0cm×0.5cm长方形上颌窦游离骨折片,然后通过两种不同方法固定骨折片,8周后处死。通过大体标本、组织学切片来评估。结果两组兔上颌窦骨折片均愈合良好,组织学HE切片也显示为正常骨小梁。结论医用胶固定兔上颌窦游离骨折片短期内效果良好,值得临床应用。

Comparation between Medical Glue and Rigid Internal Fixation for The Free Fragment of Rabbit Maxillary Sinus

Objective To investigate the results of the free fragment of rabbit maxillary sinus which treated by medical glue and rigid internal fixation.Methods Totally 8 rabbits were randomly divided into 2 groups: the medical glue group(n=4) and the control group(n=4).The free fragment was fixed with Titanium plate and screws.Approximately 1.0cm × 0.5cm rectangular free fragment were man-made in both groups,and then were fixed by two different methods above-mentioned.The specimens were harvested 8 weeks later and evaluated by the macrographs and the HE stain slices.Results The macrographs and the HE stain slices showed all the specimens healed well.There was no obvious difference between both groups.Conclusion The free fragment of rabbit maxillary sinus fixed by medical glue could get good bony healing in a short period.
