Superior canal dehiscence in a patient with three failed stapedectomy operations for otosclerosis: a case report.

Lehmann M, Ebmeyer J, Upile T, Sudhoff HH - J Med Case Rep (2011)

Bottom Line: We present the case of a 48-year-old German Caucasian woman presenting with hearing loss on the left side and vertigo.She had undergone three previous stapedectomies for hearing improvement.Reformatted high-resolution computed tomographic scanning and the patient's history confirmed the diagnosis of concurrent canal dehiscence syndrome.

ABSTRACT

Introduction: This case illustrates that superior semicircular canal dehiscence syndrome can be associated with a "pseudo"-conductive hearing loss, a symptom that overlaps with the clinical appearance of otosclerosis.

Case presentation: We present the case of a 48-year-old German Caucasian woman presenting with hearing loss on the left side and vertigo. She had undergone three previous stapedectomies for hearing improvement. Reformatted high-resolution computed tomographic scanning and the patient's history confirmed the diagnosis of concurrent canal dehiscence syndrome.

Conclusion: Failure of hearing improvement after otosclerosis surgery may indicate an alternative underlying diagnosis which should be explored by further appropriate evaluation.

Mentions: We present the case of a 48-year-old German Caucasian woman who presented with hearing loss on the left side and vertigo. The patient had a history of three previous stapedectomy operations carried out elsewhere to improve her hearing loss (Figure 1). The first operation was performed for the diagnosis of otosclerosis. The next two operations were performed to improve her persistent hearing loss and vertigo.
