Delayed Positional Vertigo after Stapes Surgery: Jin Woo Park, Joon Hee Lee, Mee Hyun Song, Dae Bo Shim; Res Vestib Sci. 2015;14(4):147-151.

Abstract PDF: Postoperative vertigo can occur after stapes surgery in approximately 5% of the patients, which more commonly presents immediately after surgery rather than in the delayed period. Isolated delayed vertigo after stapes surgery is commonly related to perilymphatic fistula. Herein we report a 36-year-old female patient who developed positional vertigo 18 days after stapes surgery demonstrating severe geotropic horizontal positional nystagmus on both sides during supine roll test. This patient was eventually diagnosed as the horizontal semicircular canal benign paroxysmal positional vertigo (BPPV) on the left side. This is a rare case of delayed vertigo following stapes surgery caused by BPPV rather than perilymphatic fistula.

Cochleovestibular Otosclerosis Without Conductive Hearing Loss: Woo Sung Na, Sang Hyun Park, Chung Ku Rhee, Jae Yun Jung; Res Vestib Sci. 2013;12(1):22-26.

Abstract PDF: Otosclerosis typically starts around stapes footplate presenting conductive hearing loss initially. However, otosclerosis may involve cochlea and vestibule causing sensorineural hearing loss and dizziness. We report a case of cochleovestibular otosclerosis without conductive hearing loss featuring Meniere’s disease.

A Case of Otosclerosis with Meniere’s Symptom: Dong Woo Hyun, Se Ra Park, Sung Huhn Kim, Won Sang Lee; Res Vestib Sci. 2009;8(2):174-177.

Abstract PDF: It has been postulated that otosclerosis may produce vertigo by several mechanisms. An association between otosclerosis and Meniere’s disease has been proposed on both a clinical and histopathologic basis but the causal relationship is controversial. We report a case of bilateral otosclerosis in a man manifesting vertiginous symptoms. Fifty one year-old man was examined for rotational vertigo and poor hearing in his both ear for ten years. The audiogram revealed left sided hearing loss of a conductive type and right sided sensorineural hearing loss, and caloric asymmetry. Meniere’s disease was suspected, but temporal bone CT showed low attenuated lesion around bilateral cochlear and semicircular canal. A diagnosis of otosclerosis was made. He was recommended sodium fluoride therapy. Severe endolymphatic hydrops manifesting itself as Meniere’s disease can be the result of otosclerosis, so vertiginous and concurrent hearing symptoms should not be overlooked.
