Superior Semicircular Canal Dehiscence Syndrome Manifested as Menière’s Disease: A Case Report: Byeong Jin Kim, Yun Na Yang, Chan Mi Lee, Eun Jung Lee; Res Vestib Sci. 2021;20(3):108-112. Published online September 15, 2021; DOI: https://doi.org/10.21790/rvs.2021.20.3.108

Abstract PDF: The absence of a temporal bone overlying the superior semicircular canal causes superior semicircular canal dehiscence (SSCD). The vestibular symptom of SSCD syndrome (SCDS) is vertigo and audiologic symptoms include autophony, hyperacusis, and ear fullness. A 52-year-old man presented with left-sided unilateral hearing loss, aural fullness, and recurrent spinning-type vertigo. He had positive Hennebert sign and mixed-type hearing loss, with a prominent low-frequency air-bone gap. These symptoms reminded us of SCDS, and computed tomography (CT) revealed SSCD. However, the patient had not experienced vertigo until 1 week prior to the visit. In addition, the audiogram revealed fluctuation of hearing, which was aggravated when the vestibular symptoms manifested. Vertigo might be due to Menière’s disease rather than SCDS and SSCD was incidentally detected on CT. According to reviews, this is no reported case of SCDS manifested as Menière’s disease, so we report this case with a brief review of the literature.

Two Cases of Pediatric Pneumolabyrinth with Traumatic Tympanic Membrane Perforation after Penetrating Injury: Yeon Seok You, Ji Hoon Koh, Byeong Jin Kim, Eun Jung Lee; Res Vestib Sci. 2019;18(3):83-86. Published online September 15, 2019; DOI: https://doi.org/10.21790/rvs.2019.18.3.83

Abstract PDF: Pneumolabyrinth is an uncommon condition in which air is present in the vestibule or cochlear. It is rarely found, even in otic capsule violating fractures or in transverse fracture of the temporal bone. So far, there is no consensus on management of pneumolabyrinth. We describe 2 new cases of pneumolabyrinth by penetrating injury with traumatic tympanic membrane perforation. They presented whirling vertigo with moderate conductive hearing loss. Temporal bone computed tomography clearly demonstrated the presence of air in the vestibule and cochlear.
