Abstract：
UNASSIGNED: Sigmoid sinus diverticulum/dehiscence (SSD) is one of the treatable causes of venous pulsatile tinnitus. It can be diagnosed using temporal bone computed tomography (CT) or magnetic resonance angiography/venography (MRA). In cases where patients find their symptoms intolerable, surgical treatment is typically preferred. Here, we have presented a novel surgical technique involving sigmoid sinus re-roofing and have analyzed its feasibility.
UNASSIGNED: Between January 2020 and July 2023, approximately 150 patients with pulsatile tinnitus were evaluated at two different tertiary hospitals. Of these, 12 patients were diagnosed with SSD, and seven underwent surgical treatment. Five patients were treated with tailored reroofing (TRR) of the sigmoid sinus and two with transmastoid resurfacing (MRS) of the sigmoid sinus. We compared the Korean tinnitus handicap inventory (K-THI) score, pure tone audiogram (PTA) threshold, and CT findings before and a month after surgeries for these two techniques. The operation time was also analyzed.
UNASSIGNED: In TRR cases, the K-THI score reduced from 55.0 ± 31.4 preoperatively to 4.0 ± 3.0 postoperatively, and the SSD was well-repositioned and covered by a bone chip postoperatively. In MRS cases, the K-THI score reduced from 41.0 ± 9.9 preoperatively to 15.0 ± 21.2 postoperatively, and the SSD was well-covered with bone cement postoperatively. The average surgical time of five TRR and two MRS cases were 77.5 ± 32.5 and 174.0 ± 75.0 min, respectively. No complications were noted.
UNASSIGNED: Despite the insufficient number of cases, we noted that TRR requires a reasonable amount of time, involves a smaller incision, and may provide favorable outcomes compared to conventional MRS in cases of pulsatile tinnitus associated with SSD.

摘要：
■乙状窦憩室/裂开（SSD）是静脉搏动性耳鸣的可治疗原因之一。可以使用颞骨计算机断层扫描（CT）或磁共振血管造影/静脉造影（MRA）进行诊断。如果患者发现他们的症状无法忍受，通常首选手术治疗。这里,我们提出了一种新的手术技术，涉及乙状窦重顶，并分析了其可行性。
■在2020年1月至2023年7月之间，在两家不同的三级医院评估了约150例搏动性耳鸣患者。其中,12例患者被诊断为SSD，七人接受了手术治疗。5例患者接受了乙状窦的量身定制的修复（TRR）治疗，2例接受了乙状窦的乳突表面修复（MRS）治疗。我们比较了韩国耳鸣障碍清单（K-THI）得分，纯音听力图（PTA）阈值，以及这两种技术在手术前和手术后一个月的CT结果。还分析了手术时间。
■在TRR情况下，K-THI评分从术前55.0±31.4降至术后4.0±3.0,SSD在术后很好地重新定位并被骨片覆盖。在MRS案例中，K-THI评分从术前41.0±9.9降至术后15.0±21.2,术后SSD被骨水泥充分覆盖。5例TRR和2例MRS的平均手术时间分别为77.5±32.5和174.0±75.0min,分别。未发现并发症。
■尽管病例数量不足，我们注意到TRR需要合理的时间，包括一个较小的切口，在与SSD相关的搏动性耳鸣的情况下，与常规MRS相比，可能提供有利的结果。
