| 目的 基于HRCT评估成人永存岩鳞窦（PSS）发生率及其影像学表现。方法 回顾性分析接受薄层HRCT检查且双侧颞骨未见异常的708例成年患者资料。基于0.67 mm层厚的标准化重建轴位、冠状位图像，评估有无PSS及其HRCT征象，包括管径、走行位置、有无局部团状扩张、有无周围骨壁缺失、有无盂后孔，分析不同性别、年龄组间PSS发生率差异。结果 本组708例（1 416侧）中，PSS发生率为10.59%（150/1 416），平均管径为（1.29±0.58）mm。女性PSS发生率为12.64%（92/728），男性为8.43%（58/688），差异有统计学意义（P=0.010）；同一性别不同侧别间PSS发生率差异均无统计学意义（男性：P=0.583，女性：P=0.372）。18~29岁组、30~39岁组、40~49岁组、50~59岁组、60~69岁组组间PSS发生率差异均无统计学意义（P均>0.05），≥70岁组较其他年龄组发生率降低（P均<0.05）。150侧PSS中，24.67%（37/150）走行于岩鳞隔内，75.33%（113/150）走行于岩鳞隔外侧骨沟；47.33%（71/150）可见盂后孔形成，36.67%（55/150）水平向外走行至皮下，10.67%（16/150）垂直向下至颞下颌关节窝；2.67%（4/150）与周围颞骨气房间骨壁缺失；4.67%（7/150）局部呈血管团状扩张。结论 HRCT可显示成人岩鳞窦；颅底或耳部术前需仔细观察，以避免医源性损伤。 |

| Objective To evaluate the prevalence and imaging characteristics of persistent petrosquamosal sinus (PSS) in adults based on HRCT. Methods Data of 708 adult patients who underwent thin-slice HRCT without bilateral temporal bone abnormalities were retrospectively analyzed. Based on the standardized reconstructed axial and coronal images with 0.67 mm layer thickness, the presence of PSS and its HRCT signs, including the mean diameter, course, saccular dilation of PSS as well as wall dehiscence and postglenoid foramina were evaluated. The differences of PSS in different genders and age groups were analyzed. Results HRCT showed that the prevalence of PSS in 708 adult patients (1 416 sides) was 10.59% (150/1 416), with the average diameter of (1.29±0.58)mm. The difference in prevalence of PSS was statistically significant between women (92/728, 12.64%) and men (58/688, 8.43%). No significant difference in the prevalence was shown between sides of each gender (Pmale=0.583, Pfemale=0.372). There was no significant difference in the prevalence of PSS between each two groups among the 18-29 years old group, the 30-39 years old group, the 40-49 years old group, the 50-59 years old group (all P>0.05), while there were significant differences in the prevalence of PSS between the ≥ 70 years old group and each other groups above, respectively (all P<0.05). In 150 sides PSS, 24.67% (37/150) coursed in the petrosquamosal fissure, 75.33% (113/150) in the outer sulcus of the fissure, while 47.33% (71/150) showed postglenoid foramina formed, including 36.67% (55/150) horizontal ones to the outer subcutaneous tissue and 10.67% (16/150) into the temporomandibular joint; 2.67% (4/150) had dehiscent wall; 4.67% (7/150) had saccular expansion. Conclusion HRCT can show the characteristics of PSS, which should be carefully evaluated before skull base or ear surgeries to avoid iatrogenic injury. |
