Abstract

Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder. It is easily cured with canal repositioning maneuvers, but some patients are resistant to the repositioning maneuver and require surgical intervention. Labyrinthitis ossificans is the pathologic condition that fibrous tissue and new bone occupy the membranous labyrinthine space. It occurs as a sequela of inner ear inflammation resulting from diverse causes, mostly bacterial meningitis and otitis media. We describe here a 42-year-old female patient with refractory posterior semicircular canal (PSCC) BPPV and adhesive otitis media in same ear. Otoscopic examination revealed adhesive tympanic membrane without middle ear space and temporal bone computed tomography showed complete ossification of the labyrinth at the same side. We performed a canal wall down mastoidectomy and PSCC occlusion. The patient had complete resolution of paroxysmal vertigo and positional nystagmus, postoperatively.
