| 目的:对胆脂瘤型中耳炎听骨病变情况进行分析,探讨听骨再利用的可行性.方法:收集胆脂瘤型中耳炎患者42块听骨,进行组织学检查.结果:31块听骨出现异常改变,其中20块听骨间隙有炎症反应或骨髓炎反应,11块听骨有骨破坏.5例听骨表面有复层鳞状上皮残留.3例在上皮下结缔组织中出现胆固醇肉芽肿.结论:胆脂瘤型中耳炎听骨不宜进行听骨链重建术. |

| Abstract: |
| The surgical specimen from total laryngectomy and partial hypopharyngectomy in 43 cases of pyriform sinus carcinoma were histopathological studied by whole tissue serial sectioning. The results are as follows:In laryngeal ones the thyroid cartilages were invaded more frequently than the othesrs, and particularly the interior wall of which was invaded in the highest frequency.Invasion of laryngeal cartilage in pushing and pressing pattern was obviously more common than those in infiltrating and destroying ones,showing the laryngeal cartilage and its membranes are the anatomical obstacle against cancerous spread.Invasion of the bottom and rear edge of the thyroid cartilage maybe the reason of the invasion of thyroid gland. |
