Dizziness due to intravestibular protrusion of prosthesis after stapedectomy

Suheil Artul


We present a case of 37 year-old female with severe dizziness for the past six months whose past medical history revealed stapedectomy due to otosclerosis two years prior to visiting our hospital. Coronal high resolution computed tomography reconstruction showed the protrusion of a metallic device “peosthesis”, which had been used to replace the stape bone, to the vestibule of inner ear. The patient was re-operated for revision and replacing the prosthesis with good clinical outcome.



Dizziness; stapedectomy; intravestibular; protrusion.
