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: After the third operation, the patient came to our unit with persistent amblyacousia as well as severe vertigo and headache. Pure tone audiometry showed a maximal conductive hearing loss. The patient located in her left ear the sound of a tuning fork pressed on the right ankle. This phenomenon suggested SCD. Further high-resolution computed tomographic (CT) scans and audiometery were performed. A CT scan revealed superior semicircular canal dehiscence (Figure 2).
