Abstract

Background: Superior semicircular canal dehiscence (SSCD) is a rare bone defect in the petrous part of the temporal bone. In this syndrome, a third window is created between the middle cranial fossa and the bony labyrinth of the inner ear which can lead to stimulation of the vestibular system by sound. Patients usually have symptoms such as vertigo, imbalance, autophony, pulsatile tinnitus, and aural fullness. The clinical symptoms of this disease vary from person to person. The Case: This study reports a case of a rare bilateral SSCD in a 39-year-old woman with imbalance and autophony problems. The audiological findings showed a bilateral mild conductive hearing loss at low frequencies with symptoms of vertigo and torsional nystagmus. The SSCD was diagnosed by computed tomography. Then, the patient underwent bone repair surgery. Auditory and balance tests were performed again after the surgery to evaluate the extent of recovery. Conclusion: The SSCD can be diagnosed by using the mentioned test battery. By choosing the appropriate treatment methods and following up of the outcomes, most of the problems of patients with SSCD can be solved. Keywords: Superior semicircular canal dehiscence; bilateral; conductive hearing loss

双侧上半规管破裂表现为传导性听力损失并伴有前庭症状:一个客户中心病例报告
背景:上半规管开裂(SSCD)是一种发生在颞骨岩部的罕见骨缺损。在这种综合征中,在颅中窝和内耳的骨迷路之间产生了第三个窗口,它可以通过声音刺激前庭系统。患者通常有眩晕、失衡、自音、搏动性耳鸣、耳廓充盈等症状。这种疾病的临床症状因人而异。病例:本研究报告了一例罕见的双侧SSCD,患者为39岁女性,伴有失衡和自音问题。听力学结果显示双侧轻度低频传导性听力丧失,伴有眩晕和扭转性眼球震颤的症状。通过计算机断层扫描诊断SSCD。然后,患者接受了骨修复手术。术后再次进行听觉和平衡测试以评估恢复程度。结论:SSCD可通过上述试验电池进行诊断。通过选择合适的治疗方法和随访疗效,可以解决SSCD患者的大部分问题。关键词:上半规管开裂;两国;传导性听力损失
