Abstract:
Superior semicircular canal dehiscence syndrome (SCDS) is characterized by cochleovestibular hyper-responsiveness symptoms including sound- and pressure-evoked vertigo and oscillopsia, autophony, hyperacusis and ear fullness. The typical audiometric feature of SCDS is known as conductive hearing loss at low frequency. A 43-year-old man presented with unilateral sudden deafness after several events of heading during soccer game. High-resolution temporal bone computed tomography revealed a dehiscence of superior canal encased by superior petrous sinus. We reviewed audio-vestibular findings in this patient and speculated potential pathogenic mechanisms of sudden deafness in SCDS with literature review.
