分泌性中耳炎等CT征象与鼻咽部疾病诊断的相关性研究

A STUDY ON CORRELATION BETWEEN THE CT FEATURES OF SECRETORY OTITIS MEDIA ETC AND DIAGNOSIS OF NASOPHARYNGEAL DISEASES

目的 :研究不同性质鼻咽部疾病与分泌性中耳炎的相关性及鼻咽部病变在颅面部 CT侧位 CR像上的表现 ,旨在提高鼻咽部疾病的早期发现及正确诊断率。方法 :对 2 71例不同性质鼻咽部疾病病例的临床及 CT图像资料进行分析。结果 :分泌性中耳炎伴发率最高的鼻咽部疾病为鼻咽癌 (NPC) ,其分泌性中耳炎伴发率与其他病种比较差异有统计学意义 (P <0 .0 5 ) ;2 0 9例患者 CT侧位 CR像显示鼻咽顶和 (或 )后壁增厚隆起或鼻咽腔密度增高等表现。结论 :分泌性中耳炎 CT表现及前述的CR像异常征象是早期发现和诊断鼻咽部疾病的重要线索 ;分泌性中耳炎 CT征象还可作为

Objective:To study the correlation between the secretory otitis media and various nasopharyn geal diseases and the CT features of nasopharyngeal diseases on Computed Radiography Image (CRI), in order to improve the early diagnosis of nasopharyngeal diseases.Methods:The CT image data and clinic characteristics of 271 cases with various nasopharyngeal diseases were analyzed.Result:The frequency of secretory otitis media of the nasopharyngeal carcinoma(NPC)group was higher than that of the others (P<0 05). The CRI showed the thickened roof and posterior wall of the nasopharynx or the raised density of the nasopharyngeal cavity on 209 cases.Conclusion:The CT features of secretory otitis media and the abnormal CRI signs mentioned above are the important clues for the accurate early diagnosis of nasopharyngeal diseases, and the CT features of secretory otitis media are very valuable in differentiating NPC from other nasopharyngeal diseases.
