Abstract

Background: Sigmoid sinus wall reconstruction (SSWR) is an effective treatment for pulsatile tinnitus (PT). However, follow-up postoperative imaging manifestations have not been extensively reported.

Purpose: To evaluate the morphological changes in patients with PT after successful SSWR using ultra-high-resolution computed tomography (U-HRCT).

Material and methods: Data were retrospectively analyzed from 10 patients with PT who underwent successful SSWR primarily with autologous bone powder. U-HRCT scans were performed within 3 days of surgery and repeated 6 months later. The integrity, relative density, extent, and shape of the repaired wall were analyzed. The chi-square test was used to compare the categorical variables and the Phi (φ) coefficient was used to represent the magnitude of the correlation.

Results: Among the 10 patients with PT, 1 (10%) achieved complete coverage of the defect with the residual bone, 8 (80%) had partial coverage, and 1 (10%) showed complete separation. A gap between the repaired wall and residual bone in the initial U-HRCT was linked to incomplete defect coverage in the subsequent U-HRCT scan (P < 0.001, φ = 0.903). The repaired wall shrank from the periphery to the center and the density increased. The repaired wall compressed into the sigmoid sinus retracts over time, reshaping into a naturally curved sigmoid sinus sulcus.

Conclusion: Morphological remodeling is a typical characteristic of the repaired sigmoid sinus wall in patients with PT. Short-term incomplete repair may imply incomplete coverage of the defect in the future, but this is not correlated with recurrence.

搏动性耳鸣患者手术重建成功后修复的乙状窦骨壁形态重塑:超高分辨率 CT 研究。
背景:乙状窦壁重建术(SSWR)是治疗搏动性耳鸣(PT)的有效方法。目的:使用超高分辨率计算机断层扫描(U-HRCT)评估成功接受乙状窦壁重建术(SSWR)后 PT 患者的形态学变化:对主要使用自体骨粉成功进行SSWR的10例PT患者的数据进行回顾性分析。术后 3 天内进行 U-HRCT 扫描,6 个月后重复扫描。对修复壁的完整性、相对密度、范围和形状进行了分析。采用卡方检验比较分类变量,并用腓系数(φ)表示相关性的大小:在 10 位 PT 患者中,1 位(10%)实现了缺损与残余骨的完全覆盖,8 位(80%)实现了部分覆盖,1 位(10%)出现了完全分离。在初次 U-HRCT 扫描中,修复后的壁与残留骨之间存在间隙,这与随后的 U-HRCT 扫描中缺损覆盖不完全有关(P 结论:缺损覆盖不完全与缺损形态重塑有关:形态重塑是 PT 患者修复后乙状窦壁的典型特征。短期的不完全修复可能意味着未来缺损的不完全覆盖,但这与复发无关。
