Abstract：
OBJECTIVE: Sigmoid sinus wall anomalies (SSWA) are closely linked to venous pulsatile tinnitus (PT). This study aims to demonstrate that SSWA develops progressively rather than being congenital.
METHODS: We retrospectively analyzed 42 PT patients with SSWA who had at least two non-operative CT scans at our clinic. CT images were longitudinally assessed to track SSWA progression, while MRI and Doppler ultrasound evaluated transverse sinus stenosis and venous hemodynamics. Changes in PT perception were tracked using the tinnitus handicap inventory (THI) questionnaire.
RESULTS: Among the 42 SSWA patients, 12 (28.6%) exhibited progression. Anastomosis between diploic vein and diverticulum was significantly higher compared to the dehiscence cohort (p < 0.01). Within the diverticulum group, seven individuals (30.4%) experienced enlargement, with a mean diverticular wall expansion of 5.9% ± 11.4%. Progressive erosion was observed in two cases (12.5%) in the dehiscence cohort, with a mean sigmoid plate erosion of 3.8% ± 10.1%. In cases progressing from dehiscence to diverticulum, three subjects transitioned, with a mean sigmoid sinus wall length expansion of 43.8% ± 31.9%. SSWA progression showed a significant negative correlation with QBILATERAL (r = -0.857, p = 0.014), and there was a significant difference between initial and revisit THI scores (p < 0.01).
CONCLUSIONS: SSWA can undergo morphological progression, indicating it is a progressive clinical condition rather than congenital.

摘要：
目的：乙状窦壁异常（SSWA）与静脉搏动性耳鸣（PT）密切相关。这项研究旨在证明SSWA逐渐发展而不是先天性的。
方法：我们回顾性分析了42例SSWAPT患者，这些患者在我们的诊所进行了至少两次非手术CT扫描。纵向评估CT图像以跟踪SSWA进展，而MRI和多普勒超声评估横窦狭窄和静脉血流动力学。使用耳鸣障碍清单（THI）问卷跟踪PT感知的变化。
结果：在42例SSWA患者中，12（28.6%）出现进展。与裂开组相比，二倍体静脉和憩室之间的吻合明显更高（p<0.01）。在憩室组中，7人(30.4%)经历了扩大，平均憩室壁扩张为5.9％±11.4％。在开裂队列中有2例（12.5％）观察到进行性侵蚀，乙状结肠平均侵蚀3.8%±10.1%。在从裂开发展到憩室的情况下，三个科目过渡，平均乙状窦壁长度扩张为43.8%±31.9%。SSWA进展与QBILATERAL呈显著负相关(r=-0.857,p=0.014),初始和再访问THI评分之间存在显着差异（p<0.01）。
结论：SSWA可以进行形态学进展，这表明这是一种进行性的临床疾病，而不是先天性的。
