We describe the clinical evaluation and operative management of posterior semicircular canal dehiscence caused by a high jugular bulb.
We performed a retrospective case report.
The patient had clinical and audiometric findings consistent with semicircular canal dehiscence and imaging findings that demonstrated erosion of the posterior semicircular canal by a high jugular bulb. Resurfacing of the eroded canal provided resolution of the vestibular symptoms without damage to the inner ear.
Dehiscence of the posterior semicircular canal can cause clinical and audiometric findings similar to those of superior semicircular canal dehiscence syndrome. Resurfacing of the area of dehiscence can successfully relieve the vestibular symptoms. In the case of dehiscence of the posterior canal from a high jugular bulb, resurfacing may offer advantages over canal plugging for definitive management.
我们描述了由高位颈静脉球引起的后半规管裂开的临床评估和手术管理。
我们进行了一项回顾性病例报告。
该患者的临床和听力检查结果与半规管裂开一致，影像学检查结果显示高位颈静脉球对半规管造成侵蚀。对受侵蚀的半规管进行表面修复可缓解前庭症状，且不损伤内耳。
后半规管裂开可导致与上半规管裂开综合征相似的临床和听力检查结果。对裂开区域进行表面修复可成功缓解前庭症状。对于由高位颈静脉球引起的后半规管裂开，与半规管堵塞相比，表面修复在确定性治疗方面可能具有优势。
