Objective To probe the possibility of a new technique of primary cleft palate repair by sutural distraction osteogenesis. Methods The distractor was made of TiNi-shape memory alloy with 2 secure and 2 active arms.Under general anesthesia,1 hole was drilled on each maxillary process and horizontal plate of palatine.The four arms of the distractor were inserted into holes.The palatine bones would then be distracted and moved medially and posteriorly.After 4 to 5 months' distraction,the two cleft edges...

Objective To probe the possibility of a new technique of primary cleft palate repair by sutural distraction osteogenesis. Methods The distractor was made of TiNi-shape memory alloy with 2 secure and 2 active arms.Under general anesthesia,1 hole was drilled on each maxillary process and horizontal plate of palatine.The four arms of the distractor were inserted into holes.The palatine bones would then be distracted and moved medially and posteriorly.After 4 to 5 months' distraction,the two cleft edges approached gradually.The residual cleft,according to its width,was repaired by direct stitch of muco-periosteum incised at cleft edges,or with an additional relaxing incision on one side of the palate.Direct measurement of width of maxillary arch and the cleft,and the length of the hard palate was performed before and after distraction to evaluate the effects of distraction. Results Eight cleft children at their 2 to 4 years of age were treated by the new technique.Two of them terminated the procedure due to premature dislocation of the distractor.Six children underwent 37 to 126 days'distraction.Dramatic narrowing of the cleft and lengthening of hard palate were seen in these children,with the average narrowing of the cleft being 6 5mm and average lengthening of the hard palate being 4 8mm. Conclusion It is clinically demonstrated that palatal tissue regeneration and cleft closure or narrowing and hard palate lengthening could be achieved by the technqiue of sutural distraction osteogenesis.;

目的 临床探索骨缝牵引成骨修复腭裂的新技术。方法 选择 2~ 4岁的腭裂患儿。一期手术在全麻下安置腭裂牵引器 ,牵引腭骨向中线和向后移动 ;牵引期持续约 4~ 5个月。裂隙合拢后进行二期手术 ,修复裂隙。用误差为 0 2 %的游标卡尺 ,测量牵引前和牵引后上颌牙弓宽度、裂隙宽度和硬腭长度。结果 临床应用 8例。 2例因牵引器在安置后 1周内脱落而终止牵引。 6例经不同时间的牵引后 ,裂隙缩小 ,裂隙两侧的组织显著延长。其中牵引时间最长为 12 6d ,最短为 37d ;裂隙宽度平均缩小 6 5mm ;硬腭长度平均延长 4 8mm。结论 临床证实了骨缝牵引具有诱导腭部组织再生、关闭或缩小裂隙和延长硬腭的可能性。

Objective To probe the feasibility of a new technique of sutural distraction osteogenesis for midface hypoplasia repair. Methods A protraction system was developed, which consisted of three parts: a rigid external framework, a bone hook, and the elastic band. Four 12-week mongreal dogs were randomly assigned into two groups:the control( n =1) and the experimental groups ( n=3 ).Four pairs of titanium bone markers were fixed on either side of the bone sutures of all animals.

Objective To probe the feasibility of a new technique of sutural distraction osteogenesis for midface hypoplasia repair. Methods A protraction system was developed, which consisted of three parts: a rigid external framework, a bone hook, and the elastic band. Four 12-week mongreal dogs were randomly assigned into two groups:the control( n =1) and the experimental groups ( n=3 ).Four pairs of titanium bone markers were fixed on either side of the bone sutures of all animals. The experimental group was fitted with a distraction device, through which a forward elastic force was exerted for 1 month. Clinical observations and X-ray examinations were performed at the beginning and the end of distraction.New bone specimens were examined histologically. Results All the animals in the experimental group showed progressively forward movement of the maxilla and manifested class Ⅱ occlusion at the end of the experiment.The distance increase between each pair of bone markers showed that premaxilla advancement was more than that of the maxilla.The next was zygoma.There was no obvious difference between the control and the experimental group in terms of the basilar-maxillary angle and counterclockwise rotation. Theer was active osteogenesis in the sutures, especially in premaxilla-maxillary sutures. The number of osteoblasts and fibroblasts increased dramatically and new bone formation was found at the edge of the suture. Conclusion This technique can create effective advancement of the maxilla.The direct force can avoid counterclockwise rotation of the maxilla during distraction.

目的 探索缝牵引成骨修复面中部发育不全的新技术。方法 同窝 12周龄杂种犬 4只 ,随机分为空白对照组 1只 ,实验组 3只。分别在两组犬前颌缝、腭横缝、颧颌缝、颧颞缝的前后种植钛钉 ,作为骨标志。实验组安置特制外置式牵引支架和牵引钩 ,将牵引钩插入鼻腭孔 ,橡皮圈连接外置支架和牵引钩 ,向前持续弹性牵引 1个月 ,牵引力约为 6 0 0g ,牵引前后进行临床和X线检查及头影测量。于 16周龄时将两组犬均处死 ,进行组织学观察。结果 上颌逐渐前突 ,咬合关系呈现Ⅱ类错咬合。骨缝前后骨标志点间距离测量结果提示 ,前颌骨前移最明显 ,上颌骨次之 ,颧骨前移不多。对照组与实验组颅底角度变化幅度不明显 ,上颌未见旋转发生。实验组各犬的骨缝有大量新骨生成 ,大量的成骨细胞 ,成纤维细胞沿张力方向排列 ,前颌缝尤为明显。结论 本牵引装置可有效地平行前移上颌 ,作用力更直接 ,避免了上颌的旋转 ,牙移位。

Objective To explore a new technique for repair of alveolar cleft by sutural distraction osteogenesis. Methods Nine 8-weeks mongrel dogs were used in this study,three being in the control group,six in the experimental group.Alveolar cleft model was created surgically in all animals. Two weeks later,a U-shaped distractor made of Ni-Ti memory alloy wire was insterted into the premaxilla to distract the mid-premaxillary suture.When the premaxilla of the cleft side approached the ipsilateral maxilla,periosteoplasty of the alveolar cleft was performed.The distractor was removed at two weeks after periosteoplasty.The results were evaluated clinically,radiographically,morphologically and histologically. Results The cleft model in dogs was stable and similar to the human alveolar cleft. In experimental dogs,the premaxilla was moved gradually toward the maxilla so that the cleft was closed. The distracted mid-premaxillary suture showed a gradually widened traingle,with its tip being posterior.The density of the distracted traingle suture was increased gradually.Bony repair was achieved completely at the cleft three months post-periosteoplasy.The morphology of the mid-premaxillary suture was restored. Conclusion The alveolar cleft could be repaired by the technique of mid-premaxilla suture distraction.

目的 探索用缝牵张成骨技术以组织再生的原理修复牙槽裂。方法 采用犬牙槽裂模型 ,牙槽裂形成术后 2周 ,于前颌中缝处安置缝牵张器 ,外张力 2 0 0g。牵张 2~ 3周 ,裂隙侧的前颌骨向侧方移动贴紧远中裂缘 ,用局部黏骨膜瓣修复牙槽裂隙。保持 2周后去除缝牵张器。临床观察、连续X线、头颅干骨和组织学检查评价治疗结果。结果 所有对照动物形成规则的牙槽裂 ,无自发骨性愈合。前颌中缝牵张后 ,裂隙侧前颌缓慢向裂侧上颌靠拢 ,2~ 3周与远中裂缘密切贴合。X线片示前颌中缝呈现由窄渐宽的三角形 ,三角形的尖端指向后方 ,三角区域的骨密度逐渐增加。骨膜成形术后 3个月 ,原牙槽嵴缺损处骨质连续性完全恢复 ,且牙槽骨段在三维方向上均与对侧相同。前颌中缝恢复正常直线形态。结论 该牙槽裂模型稳定性和重复性好 ;前颌中缝牵张诱导缝区新骨形成 ,一侧前颌向裂隙移位和局部骨膜成形可达到完善的牙槽裂修复。
