From 1980 to 1984,congenital microgenia of 12 cases was reconstructed withsolid silicone implant.The implant was placed anterior to the mental region,exceptone in submental region.In order to obviate dead space and undue tension,a supra-periosteal pocket just large enough to accommodate the silicone implant was created.Itis necessary to anchor the implant to the periosteum with one or two buried suturesto prevent displacement of the implant due to laxity of the skin with increasing age.This technique of chin augmentation is simpler than the onlay bone graft oradvancement of the lower portion of the mandible by horizontal osteotomy.All 12cases were without any complication and obtained satisfactory cosmetic results.

1980年6月起,作者等采用硅橡胶充填整复轻、中度小颌畸形12例(起初7例用块状硅橡胶雕刻成型,后5例用成型硅橡胶制品)。本法较自体髂骨充填法或锯断部分下颌缘的下颌骨前移术简单易行。12例均无不良反应,整复后外形满意。

Objective The experimental study was to determine the differences in changes in the onlay bone grafts of different embryonic origin.WTHZMethods The study was designed to compare the potential for appositional bone growth in membranous and endochondral onlay grafts in NewZealand rabbits and a rhesus monkey.Results were assessed with volumetric measurement,histological examinations and stereologic analysis with doublefluorochrome labeling technique. Results For the membranous and endochondral bone grafts,the volumetric retention rate was (78.43.5)% and (56.05.1)% respectively.The mineralization apposition rate (MAR) was (3.60.8) m/d and (0.920.33)m/d;the osteoid seam width (OSW) was (14.562.69) m and (7.382.20)m;the tetracycline uptake rate(TUA) was (91.222.69)% and (51.284.11)%,respectively. Conclusion It was found that the membranous bone graft maintained its volume to a significantly greater extent than the endochondral bone graft; Membranous bone grafts exhibited higher survival rate and greater activity than endochondral bone grafts; Different changes were also found in the two recipient sites.There was more powerful bone regenerative reaction in the recipient bed of the membranous bone graft than the endochondral one.

目的深入探讨骨贴附移植后的变化及不同胚胎来源骨质(膜状成骨和软骨成骨)移植后的差异。方法应用新西兰兔、恒河猴采用荧光素双标记法,在不脱钙骨切片上,选用类骨质宽度、骨质矿化沉积率、荧光标记率等骨动力学指标对骨移植后的再生和改建进行计算机图像分析和定量测量。结果骨体积存留率:膜状成骨为(784±35)%,软骨成骨为(56±51)%;骨矿化沉积率:膜状成骨为(360±08)μm/d,软骨成骨为(092±033)μm/d;类骨质宽度;膜状成骨为(1456±269)μm,软骨成骨为(738±220)μm;荧光标记率:膜状成骨为(9122±269)%,软骨成骨为(5128±411)%。结论膜状成骨移植后较软骨成骨可保持更多的骨质体积,有更为明显的成骨再生能力且可诱导宿主骨成骨的能力不同,膜状成骨优于软骨成骨。

Objective To investigate the disparity in early revascularization of the membranous and endochondral bone grafts.Methods Twenty Wistar rats were randomly divided into two groups of 10 each.Full-thickness cranial(membranous)and split-thickness iliac crest(endochondral)onlay bone grafts were placed subperiosteally onto the snout of the animal without bony fixation.At 7 and 14 days after grafting the bone grafts together with the recipient sites were harvested.Revascularization was...

Objective To investigate the disparity in early revascularization of the membranous and endochondral bone grafts.Methods Twenty Wistar rats were randomly divided into two groups of 10 each.Full-thickness cranial(membranous)and split-thickness iliac crest(endochondral)onlay bone grafts were placed subperiosteally onto the snout of the animal without bony fixation.At 7 and 14 days after grafting the bone grafts together with the recipient sites were harvested.Revascularization was studied uti- lizing opacifying injection and computerized image analysis technique.Results The extent of vasculariza- tion at 7 days was 11.88% and 22.33% in membranous and endochondral bone grafts,respectively,and they developed to be 15.93% and 34.93% at 14 days,respectively.Conclusion The results indicated that endochondral bone grafts were more rapidly revascularized than membranous bone grafts at 7 and 14 days(P<0.05).Differences in graft architecture are theorized to account for the relationship between the vascularization and volume maintenance in the bones of different embryonic origin.

目的采用 Wistar 大鼠对颅骨(膜内成骨)和髂骨(软骨成骨)贴敷移植后早期再血管化进行了观察研究。方法用计算机图像处理进行定量分析。结果骨移植7天后,软骨成骨与膜内成骨血管密度分别为:22.33%和11.88%;14天时分别为34.93%和15.93%。结论软骨成骨移植后较膜内成骨有更加迅速的血管化。文中对骨移植后骨质结构,血管化以及骨质体积存留之间的关系进行了讨论。
