Among these, PT is usually associated with sigmoid sinus symptoms, such as sigmoid sinus wall defect or diverticulum, for which various surgical treatments are available. We have discussed the clinical efficacy of surgery for sigmoid sinus-associated PT via the transmastoid approach in this study.Methods: We conducted a retrospective review of 4 patients who underwent surgery for sigmoid sinusassociated PT via the transmastoid approach at Nanjing Drum Tower Hospital from January to December2020. Of these, 2 patients had sigmoid sinus wall defect and 2 had sigmoid sinus diverticulum. Postoperative tinnitus grading and surgical efficacy were determined.Results: After surgery, PT dissolved in 3 patients, while tinnitus significantly decreased in 1 patient.During the follow-up period of 12-18 months, none of the 4 patients showed complications related to increased intracranial pressure or venous sinus thrombosis, and tinnitus symptoms disappeared in 3patients without recurrence, although 1 patient occasionally developed tinnitus. Postoperative thin-slice CTA of the temporal bone indicated that the sigmoid sinus bone wall defect or diverticulum was completely repaired with a thick soft tissue coverage.Conclusion: Surgical repair of sigmoid sinus-associated PT via the transmastoid approach deserves clinical promotion as it exhibited better efficiency while being relatively less invasive.展开更多
目的探讨横窦-乙状窦憩室引起的搏动性耳鸣的CT表现。方法搜集18例横窦-乙状窦憩室引起的搏动性耳鸣患者资料,分析其脑CT动静脉血管造影(CT Arteriography and Venography,CTA/CTV)检查的影像表现。结果 18例横窦-乙状窦憩室均发生在静...目的探讨横窦-乙状窦憩室引起的搏动性耳鸣的CT表现。方法搜集18例横窦-乙状窦憩室引起的搏动性耳鸣患者资料,分析其脑CT动静脉血管造影(CT Arteriography and Venography,CTA/CTV)检查的影像表现。结果 18例横窦-乙状窦憩室均发生在静脉窦优势引流侧;静脉窦双能量减影图像直观地显示横窦-乙状窦憩室,表现为静脉窦管腔局部呈囊袋样、指状及棘样突起;CTV图像能清楚地显示局部膨隆的静脉窦经邻近骨壁缺损处疝入邻近的乳突。结论脑CTA/CTV检查对诊断横窦-乙状窦憩室引起的搏动性耳鸣具有重要的价值。展开更多
目的探讨磁共振增强三维扰相梯度回波序列(MRI CE 3D-SPGR)对异常乙状窦的诊断价值。方法对33例搏动性耳鸣患者行MRI CE 3D-SPGR检查,并在工作站行多平面重组、曲面重组等图像后处理,观察、测量和记录异常的乙状窦影像学表现。结果 19...目的探讨磁共振增强三维扰相梯度回波序列(MRI CE 3D-SPGR)对异常乙状窦的诊断价值。方法对33例搏动性耳鸣患者行MRI CE 3D-SPGR检查,并在工作站行多平面重组、曲面重组等图像后处理,观察、测量和记录异常的乙状窦影像学表现。结果 19例均清晰显示异常的乙状窦,对应的乙状窦沟骨壁变薄,13例显示乙状窦通过骨缺损的部位突入蜂房内形成憩室,6例显示乙状窦前壁局部边缘毛糙欠光滑,呈"锯齿"状改变。结论MRI CE 3D-SPGR对异常乙状窦具有较高的诊断价值,但在显示乙状窦沟骨壁缺损方面逊色于颞骨HRCT。展开更多
