Abstract PDF: Distinguishing central and peripheral causes of dizziness is vital. A case is presented where a 42-year-old man with a history of posterior circulation ischemic stroke developed acute unilateral vestibulopathy with hearing loss. Clinical examination revealed signs of vestibular dysfunction on the left side. Audiometry confirmed deafness on the left, but imaging ruled out new central issues. The patient was diagnosed with audiovestibulopathy and treated with steroids, antiviral agents, intratympanic injections, and hyperbaric oxygen therapy. Hearing loss persisted, but dizziness improved with vestibular rehabilitation. Poststroke patients should be closely monitored for peripheral complications. Further research should explore the benefits of antiplatelet therapy in vascular-related conditions, even without clear central lesions.

Abstract PDF: Labyrinthitis causes damage to inner ear structure, and in turn hearing loss and vertigo. Labyrinthitis is classified as otogenic labyrinthitis and meningogenic labyrinthitis. Otogenic labyrinthitis can be diagnosed early through otoscopic examination. However, when there are no characteristic neurologic symptoms in patients with meningogenic labyrinthitis, clinicians can overlook the underlying meningitis and this may lead to the peripheral vertigo. We encountered an unusual case of meningogenic labyrinthitis that is misdiagnosed as peripheral dizziness.

Abstract PDF

Labyrinthine fistula refers to a condition caused by an abnormal connection between the inner ear and surrounding structures. Most cases of that occur as a result of a complication brought about by cholesteatoma. It may also be generated by long repeated infections of a mastoid cavity that has been exposed to the outside after canal wall down mastoidectomy (CWDM). The infection is usually repeated for several years or decades after surgery. Therefore, labyrinthine fistula after CWDM is known as a late complication. In this case, labyrinthine fistula occurred in two months after surgery due to postoperative infection. Although cholesteatoma was removed after CWDM and the horizontal semicircular canal (HSCC) was not damaged during the operation, this labyrinthine fistula was thought to develop very early after surgery. Two months after surgery, the patient complained of dizziness, we identified the opened bony labyrinth and damaged endosteum of the HSCC in the patient.
