摘要
目的探讨CT平扫及CT容积重建(CTVR)技术诊断听骨链病变的临床价值。方法选取2016年7月至2018年10月期间我院耳鼻喉科收治的52例慢性化脓性中耳炎患者为研究对象。患者均接受CT检查并进行VR重建,观察和分析CT图像,以手术诊断结果为"金标准",评估CT平扫和CTVR技术对听骨链病变的诊断灵敏度和一致性。结果 CT平扫诊断锤骨、砧骨、镫骨、锤砧关节、砧镫关节病变的Kappa值分别为0.231、0.381、0.351、0.299、0.340,CTVR检查诊断上述病变的Kappa值分别为0.885、0.947、0.830、0.802、0.804;CTVR检查对锤骨、砧骨、镫骨、锤砧关节、砧镫关节等病变的诊断灵敏度分别为97.56%、100.00%、96.97%、93.33%、93.10%,均高于CT平扫(P<0.05)。结论 CT在听骨链病变诊断中有较高的临床价值,其中VTVR技术对其诊断准确性明显高于CT平扫,且与手术结果一致性非常高。
Objective To explore the clinical value of CT plain scan and CT volume reconstruction(CTVR)in the diagnosis of ossicular chain lesions.Methods A total of 52 patients with chronic suppurative otitis media admitted to otorhinola ryngological department of our hospital from July 2016 to October 2018 were selected for the study and were given CT and VR reconstruction.CT images were observed and analyzed,and the surgical diagnosis results were regarded as gold standard to assess the sensitivity and consistency of CT plain scan and CTVR technique in the diagnosis of ossicular chain lesions.Results The Kappa values of CT plain scan in the diagnosis of malleus,incus,stapes,incudomalleolar joint and incudostapedial joint lesions were 0.231,0.381,0.351,0.299,and 0.340,respectively.The Kappa values of CTVR in the diagnosis of above lesions were 0.885,0.947,0.830,0.802,and 0.804,respectively.The sensitivities of CTVR examination in the diagnosis of malleus,incus,sta pes,incudomalleolar joint,and incudostapedial joint lesions were 97.56%,100.00%,96.97%,93.33%,and 93.10%,respectively,which were higher than those of CT plain scan(P<0.05).Conclusion CT has a high clinical value in the diagnosis of ossicula r chain lesions.The diagnostic accu racy of VTVR technique is significantly higher than that of CT sca n,and the consistency with the su rgical results is very high.
