【摘要】：目的探讨咽鼓管上隐窝(STR)形态与胆脂瘤的关系及意义。方法回顾性分析经手术病理证实、STR骨性结构完整的慢性化脓性中耳炎(肉芽肿型)16例(18耳)、胆脂瘤71例(71耳)的MSCT资料,将其分成胆脂瘤组、慢性化脓性中耳炎组及正常组(所有健耳)三组,由两位经验丰富的医师分别测量各组STR前后径(AP)、横径(T)、上下径(SI),比较各组间、正常组左侧及右侧STR大小及结合STR形态前后诊断准确性。每两组间STR三径线均值行两独立样本t检验,以受试者工作特征曲线分析测量结果。结果胆脂瘤组、慢性化脓性中耳炎组、正常组左侧及右侧耳STR的AP、T和SI平均值分别为:2.82±0.87、2.99±0.74和2.53±0.71;3.65±1.21、3.39±0.72和3.57±0.4;4.25±1.22、3.75±0.99和4.02±0.98及4.06±1.08、3.80±0.71和3.80±1.03。其中胆脂瘤组与慢性化脓性中耳炎组、胆脂瘤组与正常组AP、T和SI大小差异均有统计学意义(P0.05);慢性化脓性中耳炎组与正常组及正常组不同侧别耳AP、T和SI大小差异均无统计学意义(P0.05)。结合STR形态本组诊断准确性由73.0%提高到89.9%。AP、T和SI诊断胆脂瘤的准确性分别为76.8%、69.7%和84.5%。结论胆脂瘤患耳STR主要径线显著小于慢性化脓性中耳炎患耳及所有正常耳;推测STR形态较小或为一种先天变异状态,为胆脂瘤易患因素之一,可作为影像辅助诊断依据。
[Abstract]:Objective to investigate the relationship between STR morphology and cholesteatoma in superior eustachian tube. Methods the MSCT data of chronic suppurative otitis media (16 cases with granuloma and 71 cases with cholesteatoma) proved by operation and pathology were analyzed retrospectively and divided into cholesteatoma group. In the chronic suppurative otitis media group and the normal group (all healthy ears), two experienced physicians measured the anterior and posterior diameters of STR, the transverse diameter, and the superior and inferior diameters of the two groups, respectively. In the normal group, the size of left and right STR and the diagnostic accuracy before and after combining with STR were correct. Two independent samples t test were performed on the mean value of STR three-track line between each two groups and the results were analyzed by operating characteristic curve of the subjects. Results in cholesteatoma group, chronic suppurative otitis media group and normal group, the average values of apt T and SI of STR in left and right ears were: 2. 82 卤0. 87 卤2. 99 卤0. 74 and 2. 53 卤0. 71 卤1. 71 卤3. 39 卤0. 72 and 3. 57 卤0. 44.25 卤1. 223.75 卤0. 99 and 4. 02 卤0. 98 and 4. 06 卤1. 083.80 卤0. 71 and 3. 80 卤1. 033respectively. There were significant differences in APT and SI between cholesteatoma group and chronic suppurative otitis media group, cholesteatoma group and normal group, but there was no significant difference in APT and SI between chronic suppurative otitis media group and normal group. The accuracy of diagnosis of cholesteatoma combined with STR was 73.0% to 89.9.APT and 84.55.The accuracy of diagnosis of cholesteatoma was 76.89.7% and 84.55.The diagnostic accuracy of this group was 76.8% and 84.5%, respectively. Conclusion the main diameter of STR in cholesteatoma ear is significantly smaller than that in chronic suppurative otitis media and all normal ears, and the conjecture of STR is a kind of congenital variation, which is one of the susceptible factors of cholesteatoma and can be used as the basis of imaging assistant diagnosis.
