【摘要】：目的研究胆脂瘤患者颞骨CT解剖参数与胆脂瘤的关系及意义。方法回顾性分析经手术病理证实咽鼓管上隐窝(STR)骨性结构完整的胆脂瘤患者87例(一侧患病对侧正常,设为病例组)的MSCT资料,将其分成病例组患侧组、病例组健侧组;40名正常人设为对照组。测量咽鼓管外耳道角(ATA)、STR的横径(T)、外耳道上棘乙状窦间距离(H-SS)、齿突长度(Cog)。结果对照组、病例组健侧组、患侧组ATA分别为(149.63±9.39)°、(147.13±4.90)°、(145.86±5.80)°,T分别为(3.56±0.68)mm、(3.43±0.55)mm、(3.01±0.72)mm,Cog分别为(1.71±0.34)mm、(1.68±0.44)mm、(1.31±0.36)mm,H-SS分别为(13.9±2.24)mm、(12.69±2.96)mm、(11.82±3.53)mm。对照组左右侧比较差异均无统计学意义(P0.05);对照组与病例组患侧组ATA、T、Cog、H-SS差异均有统计学意义(P0.05);病例组患侧组与健侧组仅Cog、T差异有统计学意义(P0.05),对照组与病例组健侧比较仅H-SS差异有统计学意义(P0.05)。对照组的ATA/H-SS、Cog/T、H-SS/T有低度相关性(r=0.39,-0.38,0.36;P0.05);病例组ATA/H-SS有低度相关性(r=-0.307,P0.05),其余各组数据均无相关性。结论颞骨各解剖参数构成一个整体,具有一定相关性且相互影响,部分解剖参数异常及各参数间关系失衡或使一些患者易于罹患胆脂瘤。
[Abstract]:Objective to study the relationship between CT anatomical parameters of temporal bone and cholesteatoma in patients with cholesteatoma. The MSCT data were divided into two groups: the diseased side of the case group and the healthy side of the case group. 40 normal persons in the healthy side group were set as the control group. The transverse diameter of the external auditory canal angle of the eustachian tube, the distance between the superior sigmoid sinus of the external auditory canal and the length of the odontoid process were measured. Results in the control group, the length of the odontoid process was Cog.Results in the control group, Case group, healthy side group, The ATA of the affected side was 149.63 卤9.39 掳and 147.13 卤4.90 掳respectively 145.86 卤5.80 掳T was 3.56 卤0.68 卤0.55 卤3.43 卤0.55 卤0.52 卤3.01 卤0.72 卤0.32 卤1.71 卤0.34 mm respectively. The difference of ATA between the two groups was 13.9 卤2.24 卤12.69 卤2.96 卤11.82 卤3.53mm / mm. there was no significant difference between the control group and the control group, and there was significant difference between the control group and the control group in ATAT and CogH-SS, and there was no significant difference in the left and right sides between the two groups (P < 0.05). The difference of Cogus T was statistically significant (P 0.05). The difference of H-SS between the control group and the case group was only significant (P 0.05). There was a low correlation between the control group and the control group. There was a low correlation between the ATA/H-SS of the control group and that of the control group. Conclusion there was no correlation between the data of the other groups and the ATA/H-SS of the case group. The anatomical parameters of the bone form a whole. Some of the anatomical parameters are abnormal and the relationship between the parameters is out of balance or some patients are prone to cholesteatoma.
