INTRODUCTION
The aim of this study was to evaluate the condition of the ossicular chain in patients requiring surgery for cholesteatoma.
MATERIALS AND METHODS
In a retrospective analysis, the destruction of the individual and combined bony structures of the ear was described in 166 patients with cholesteatoma who went through surgery in our Otology Center between 2003 and 2009.
RESULTS
Total (55.4%) or partial (30.7%) erosion of the incus was the most common pathology. In some cases, the long process (25.9%) and the body of incus (4.8%) were also involved. Erosion of the stapes superstructure occurred more commonly than a total loss of the bone (40.9% vs. 25.9%). Erosion of the malleus was least common. Completely intact ossicles were present in 5.5% of cases. Total ossicular erosion with an intact footplate (18.7%) and incudostapedial erosion (18%) was the most common combination of ossicular erosion. All patients with incudostapedial erosion had advanced disease (85% with multiple site involvement).
CONCLUSION
Widespread cholesteatoma results in greater ossicular erosion and poor hearing outcomes.
引言
本研究的目的是评估需要进行胆脂瘤手术的患者的听骨链状况。
材料与方法
在一项回顾性分析中，描述了2003年至2009年间在我们耳科中心接受手术的166例胆脂瘤患者耳部单个和联合骨结构的破坏情况。
结果
砧骨完全（55.4%）或部分（30.7%）侵蚀是最常见的病理情况。在某些情况下，砧骨长突（25.9%）和砧骨体（4.8%）也会受累。镫骨上部结构的侵蚀比整个骨头的完全缺失更常见（40.9%对25.9%）。锤骨侵蚀最不常见。5.5%的病例听骨完全完整。砧骨完全侵蚀伴镫骨底板完整（18.7%）和砧镫关节侵蚀（18%）是听骨侵蚀最常见的组合。所有砧镫关节侵蚀的患者都患有晚期疾病（85%有多部位受累）。
结论
广泛的胆脂瘤会导致更严重的听骨侵蚀和听力预后不良。
