    Objective The purpose of the study was to evaluate the long term effect and its influence on facial growth of suture distraction osteogenesis for closure of cleft palate. Method 14 Beagle dogs were used in the study. Six of them were in the experimental group, eight served as the control. Direct measurements were taken on dry skulls of the dogs and the data were analysed statistically.

    Objective The purpose of the study was to evaluate the long term effect and its influence on facial growth of suture distraction osteogenesis for closure of cleft palate. Method 14 Beagle dogs were used in the study. Six of them were in the experimental group, eight served as the control. Direct measurements were taken on dry skulls of the dogs and the data were analysed statistically. Results The results showed that bony healing at the midline between the two horizontal portions of the palatine bones appeared in all the experimental dogs. There were no significant differences in the variables of facial length and height between the two groups. But the facial width and the distance between the two vertical portions of the palatine bones were significantly less in the experimental dogs than the control. Conclusions It is suggested that bony repair of the cleft could be accomplished permanently with the technique of sutural distraction. this technique had no influence on facial length and height growth, but could led to underdevelopment of the width of the face and the respiratory tract of the palatal portion.

    目的 了解腭骨外侧缝牵张的长期效果和对颌面发育的影响。 方法 采用头颅测量方法对经过腭骨外侧缝牵张的 6只和正常对照 8只 Beagle犬进行了观察和分析。 结果 所有实验组犬两侧腭骨水平板均在中线形成骨性愈合。两组动物面长度和高度变量无明显差异 ,实验组面宽度 ,腭骨水平板宽度和垂直板间距均小于对照组 ,差异具有显著性意义。 结论 采用腭骨外侧缝牵张成骨的方法 ,能够使缺裂的腭骨板形成永久而完善的骨性修复 ;对面长度和高度发育无明显影响 ,但可导致面宽度和腭骨段呼吸道宽度发育不足

Results There were lots of fibroblasts, osteoblasts and capillary vessels in the distracted suture tissues one week after distration , and the fibers were...

    Objective To explore the histological change in suture of zygomatic bone for the zygomatic suture direct distraction osteogenesis. Methods The zygomatic bone was distracted by 3-D external distraction appliance without osteotomy. The specimens were taken 1,3,5 and 8 weeks after , and then examined histologically and compared with the blank contralateral side. Results There were lots of fibroblasts, osteoblasts and capillary vessels in the distracted suture tissues one week after distration , and the fibers were observed to connect the sides of suture and arranged orderly. The surfaces of the expanded suture were irregular .Bone formation was active in the expanded side. The bone trabeculae were mature and oriented in the direction of distraction in the distracted sides at 3 weeks. A great amount of new woven bones were found in 5-week specimen . New bones were formed completely 8 weeks after the distraction. Conclusions New bone formed rapidly in the distracted side of zygomatic bone under suture distraction osteogenesis without osteotomy.

    目的探索不截骨的骨缝牵张成骨组织学变化。方法采用10~13个月龄普通山羊为实验对象,每只动物左颧骨行三维牵张成骨,固定1、3、5、8周后取材,和对侧空白对照标本比较,观察缝区组织变化、新骨形成情况。结果骨缝被牵开后1周,成纤维细胞、成骨细胞、毛细血管增生,大量纤维软组织排列有序并连接骨缝两侧,骨缝两侧组织面不整齐,牵张侧成骨活跃,大量类骨质形成;3周时形成较成熟的骨小梁;5周时编织骨形成;8周时结构成熟完整。结论不截骨的骨缝三维牵张成骨,骨缝牵张侧新骨快速形成。

    Objective To try to find out the effects of Erigeron Breviscapine (EB) in suture distraction osteogenesis by observing tile expression of TGF and BMP in the maxillary suture of rabbits.Methods The self-restraint protraction devices were weared in 12 young rabbits. They were designed randomly into two groups: the control (n=6) and the experimental group (n=6). The experimental group received injection of Erigeron Breviscapine 0.4ml at either side of premaxillary suture every day. And control group accepted injection of 0.9% Nacl. After distraction 7 days and 14 days, 6 rabbits were killed. The tissues of the premaxillary bone suture from the rabbits were harvested and processed for immunohistochemistry of TGF and BMP.Results There were stronger expression in the experimental group than in the control group (P<0.05). There was stronger TGF-β expression in the 7 clays experimental group than in the 14 days control group (P<0.05). There was a great quantity of the fibroblast and blood vessel in the active osteogenesis. There were not typical active osteoblasts in the border of the bone sutures.Conclusion EB could play an important role in accelerating efficiently suture distraction osteogenesis.

    目的通过兔上颌缝牵张成骨动物实验模型,观察TGFβ和BMP在前颌缝中的表达,探讨灯盏花对上颌骨改建的作用与机理。方法年轻家兔12只,随机分为对照组6只,实验组6只,佩戴自制前牵引装置,均持续前牵上颌骨,每日于对照组两侧前颌缝局部注射单纯生理盐水0.4ml,实验组复方灯盏花素0.4ml,分别在牵引后7、14天处死动物,切取一侧前颌缝组织块,制作标本,免疫组织化学方法对TGFβ、BMP进行染色,光镜观察、灰度值分析,进行统计分析。结果实验组较对照组两因子高表达(P<0.05);TGFβ7天实验组较14天对照组高表达(P<0.05);成骨活跃者成纤维细胞增多,血管分布增多;骨缝缘无典型的活跃成骨细胞排列。结论灯盏花具有促进骨组织形成的作用,血管生成、微循环改善是机理之一;灯盏花可能具有直接成骨的功能;灯盏花促进成骨活动的机制与TGFβ的调节机制有相似之处。
