| Abstract (English): | Background: Superior canal dehiscence syndrome (Minor's syndrome) is a condition characterized by a bony defect in the superior semicircular canal (SSCC), with treatment primarily being surgical, notably through plugging of SSCC. Aims/Objectives: To examine the clinical outcome and postoperative VHIT findings after transmastoid plugging of the SSCC. Materials and Methods: Patients having a superior semicircular canal dehiscence (SSCCD) syndrome with debilitating symptoms who underwent a plugging of the SSCC via a transmastoid approach were included. Through a retrospective chart review and literature review, postop video head impulse test (VHIT) findings, pre and post-operative audiological/vestibular symptoms and audiograms were analyzed in a tertiary care university hospital. Results: All patients operated by plugging of the SSCC through a transmastoid approach had a significative post-operative VHIT deficit in the function of the SSCC (range 0.34–0.70, median gain function 0.41, mean gain function 0.46, standard deviation of 0.15, p = 0.0391) Almost all patients had improvement of their preoperative symptoms. No surgical complication was noted. The literature review also highlighted safety and effectiveness of this surgical technique. Conclusion and significance: Post-operative VHIT findings showed an elective deficit of the SSCC function thus confirming the surgical SSCC plugging through a trans mastoid approach.

| Abstract (Chinese): | 上半规管裂综合征(Minor 综合征)是一种以上半规管 (SSCC) 骨缺损为特征的疾病, 主要通过手术治疗, 尤其是通过堵塞 SSCC进行治疗。 检查经乳突堵塞 SSCC 后的临床结果和术后 VHIT 发现。 纳入了患有上半规管裂 (SSCCD) 综合征且症状严重的患者, 这些患者接受了经乳突堵塞 SSCC的治疗。通过回顾性图表审查和文献综述, 分析了三级大学医院的术后视频头部脉冲测试 (VHIT) 结果、术前和术后听力/前庭症状和听力图。 所有接受经乳突堵塞 SSCC 的患者, 术后均出现显著的 SSCC 功能VHIT缺陷(范围 0.34–0.70, 中位增益功能 0.41, 平均增益功能 0.46, 标准差 0.15, p = 0.0391)。几乎所有患者的术前症状均得到改善。未发现手术并发症。文献综述还强调了这种手术技术的安全性和有效性。 术后 VHIT 结果显示 SSCC 功能存在选择性缺陷, 从而肯定了通过乳突入路进行堵 塞SSCC的手术。 [ABSTRACT FROM AUTHOR] |
