In this artide we describe an unusual presentation of conductive hearing loss caused by otosclerosis and superior semicircular canal dehiscence (SSCD) syndrome in one patiënt. SSCD typically presents with vertigo induced by loud sounds or by increased middle ear or intracranial pressure which can be accompanied by conductive hearing loss. The dehiscence of the semicircular canal creates a third window, which causes conductive hearing loss. The presentation of SSCD with only conductive hearing loss is rare. The combination of SSCD and otosclerosis has only been described in a few case reports. When the cause of conductive hearing loss is not fully understood SSCD should be considered. When a CT-petrosum is made in the work-up for otosclerosis SSCD should be excluded.
