AIMS
To analyse bone fragments from rhinostomies of patients undergoing revisional dacryocystorhinostomy, looking for evidence of new bone formation.
METHODS
14 consecutive patients undergoing secondary lacrimal surgery were included in this study. In each case the existing rhinostomy was enlarged with bone punches, care being taken to use the punches with the jaws cutting perpendicularly to the edge of the rhinostomy, to allow accurate orientation of the specimens. The fragments were examined histologically for evidence of new bone formation.
RESULTS
Histological sections showed fragments of bone with variable fibrosis at the edge of the rhinostomy. There was evidence of only very little new bone formation.
CONCLUSION
This study has clearly shown that, at the edge of a rhinostomy, healing is predominantly by fibrosis and there is only very limited new bone formation.
目的
分析接受泪囊鼻腔吻合术修复手术患者鼻造口处的骨碎片，寻找新骨形成的证据。
方法
本研究纳入14例连续接受二次泪道手术的患者。在每例手术中，用骨凿扩大现有的鼻造口，注意使用骨凿时钳口垂直于鼻造口边缘切割，以便准确确定标本方向。对碎片进行组织学检查以寻找新骨形成的证据。
结果
组织学切片显示鼻造口边缘有不同程度纤维化的骨碎片。仅有极少新骨形成的证据。
结论
本研究清楚地表明，在鼻造口边缘，愈合主要通过纤维化进行，新骨形成非常有限。
