摘要

Objective To discuss the value of high resolution computed tomography(HRCT) in preop-erative evaluation of in patients with chronic suppurative otitis media ( CSOM) .Methods Total of 210 patients with CSOM in Shangluo Central Hospital from May 2012 to May 2015 were included in the study,including 105 cases of bone ulcer otitis and 105 cases of cholesteatoma otitis.HRCT was used to check the extent of damage of bone ulcer otitis media and cholesteatoma otitis media in incus body ,crus longum incudis,crus breve incudis,lenticular process, stirrup,malleus head and malleus handle,and compare the results with intraoperative observation.Results The extent of damage in patients with bone ulcer otitis media in the pre-operative HRCT examination compared with intraoperative results showed no statistically significant difference (P>0.05).The extent of damage in patients with cholesteatoma otitis media in the preoperative HRCT examination compared with intraoperative results showed:there were statistically significant differences in the extent of damage in crus breve incudis, lenticular process and stirrup(P <0.05),there was no significant difference in the extent of damage in the other parts ( P>0.05 ) .Conclusion HRCT plays an important role not only in the diagnosis of CSOM,but also in the preoperative evaluation and the choice of surgical methods.%目的：探讨高分辨率 CT（ HRCT）在慢性化脓性中耳炎（ CSOM）患者术前评估中的作用。方法选泽2012年5月至2015年5月商洛市中心医院就诊且诊断为CSOM的骨疡型患者105例，胆脂瘤型患者105例，术前通过HRCT来评估两型中耳炎在砧骨体、砧骨长脚、砧骨短脚、豆状突、镫骨、锤骨头和锤骨柄这7个部位的破坏情况，并与术中所观察到的两型中耳炎7个部位的破坏程度进行比较。结果骨疡型中耳炎患者在术前进行的 HRCT检查显示的破坏程度与术中观察到的结果进行比较发现，7个部位部位的听骨破坏程度差异无统计学意义（ P ＞0．05）。胆脂瘤型中耳炎患者除砧骨短脚、豆状突和镫骨部位的听骨破坏程度差异有统计学意义（ P ＜0．05），其余部位的破坏程度差异均无统计学意义（ P ＞0．05）。结论 HRCT 对 CSOM 患者手术方式的选择具有重要的作用。
