摘要: 本研究探讨高分辨率CT (HRCT)、容积重建(CTVR)诊断化脓性中耳炎听骨破坏的价值。选取化脓性中耳炎患者150例,患者均接受手术治疗。术前患者接受HRCT检查及CTVR检查,以手术后中所见结果作为诊断依据,计算HRCT、CTVR诊断听骨不同部位破坏的诊断学价值。CTVR检查诊断于锤骨头、锤骨柄部、砧骨体部、砧骨脚部、锤砧关节、砧镫关节、镫骨出现完全破坏、部分破坏的结果与手术结果比较,差异均无统计学意义(P>0.05);HRCT检查诊断于锤骨头、锤骨柄部、砧骨体部、砧骨脚部、锤砧关节、砧镫关节、镫骨出现完全破坏、部分破坏的结果与手术中所见分别比较,差异均无统计学意义(P>0.05);CTVR、HRCT联合诊断锤骨头、锤骨柄部、砧骨体部、砧骨脚部、锤砧关节、砧镫关节、镫骨,比两种方法单独使用时具有更高的灵敏度。HRCT扫描诊断化脓性中耳炎患者出现听骨不同部位破坏具有较高的灵敏度,CTVR诊断化脓性中耳炎患者出现听骨不同部位破坏具有较高的特异度,临床上可二者联合应用提高诊断效果。

Abstract: This study investigated the value of high-resolution CT (HRCT) and volume reconstruction (CTVR) in the diagnosis of ossicular destruction in suppurative otitis media. 150 patients with suppurative otitis media were selected, all patients received surgical treatment, and the preoperative patients received HRCT and CTVR examinations. The findings during and after surgery as the basis for diagnosis calculated the diagnostic value of HRCT and CTVR in diagnosing the destruction of different parts of the ossicular bone. There was no significant difference between the results of CTVR examination in the diagnosis of complete destruction or partial destruction of the malleus head, malleus stem, incus body, incus foot, malleus-anvil joint, incus-stapedius joint, and stapes with the surgical results (P>0.05). There was no significant difference between the results of HRCT examination in the diagnosis of complete destruction or partial destruction of the malleus head, malleus stem, incus body, incus foot, malleus-anvil joint, incus-stapedius joint, and stapes with what was seen during surgery (P>0.05). CTVR and HRCT combined diagnosis of malleus head, malleus stem, incus body, incus foot, malleus-anvil joint, incus-stapedius joint, and stapes have a higher sensitivity than the two methods alone. HRCT scan has a high sensitivity in diagnosing the destruction of different parts of the ossicle in patients with suppurative otitis media, and CTVR has a high specificity in diagnosing the destruction of different parts of the ossicle in patients with suppurative otitis media. Moreover, the combination of the two can be used in clinical practice to improve the diagnostic effect.
