作者等观察了25例中耳自体同种异体听骨、软骨等及人工材料移植物的组织病理学改变,这些标本取自23例听骨重建术及2例镫骨切除术的病人经再次手术者。平均年龄29岁,移植物安放于中耳的时间从5月至10年,平均2年零8个月。组织均经过脱钙、火棉胶包埋、连续切片及苏木素伊红染色。除光学显微镜观察外,并用电子计算机测量每一切片中复活骨组织(潜行取代)的面积及整个骨组织的面积,识别复活骨细胞的主要标志为骨腔隙内有细胞体及核。求得复活骨占
The authors observed the histopathological changes in 25 cases of autologous allotopic ossicles, cartilage and other artificial material grafts from the middle ear. The specimens were obtained from 23 patients undergoing ossification reconstruction and 2 mastectomy patients undergoing reoperation By. The average age was 29 years. The time for placing the graft in the middle ear ranged from May to 10 years, an average of 2 years and 8 months. Tissue after decalcification, fire cotton embedding, serial sections and hematoxylin eosin staining. In addition to the optical microscope observation, the area of the resuscitative bone tissue (sneak replacement) and the area of the entire bone tissue in each section were measured by an electronic computer. The main sign of the resurrected osteocytes was the cell body and nucleus in the bone cavity. Find resurrection bone accounted
