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.

A Case of Tumarkin Otolithic Crisis Treated with Intratympanic Gentamicin Injection: Soo Hyun Joo, Hong-Ju Kim, Hyun-Ji Kim, Kyu-Sung Kim; Res Vestib Sci. 2020;19(1):22-28. Published online March 15, 2020; DOI: https://doi.org/10.21790/rvs.2020.19.1.22

Abstract PDF: Tumarkin otolithic crisis is an abrupt attack of falling without loss of consciousness because of peripheral vestibular disorders. It occurs without warning in patients with late stage or end-stage of Meniere’s disease. It is an otologic emergency due to the risk of fall down injury, and has been treated with labyrinthectomy, vestibular neurectomy, and intratympanic gentamicin injection. Many reports have reported the efficacy of intratympanic injection of gentamicin (ITIG) as chemical ablation. We report a 58-year-old man with Tumarkin otolothic crisis from Meniere’s disease who presented with sudden drop attack while driving a taxi. He has suffered from recurrent rotatory vertigo accompanied by fluctuating hearing loss and tinnitus in the right ear for years. Despite medical treatment over the next 2 months, he experienced three more sudden drop attacks. He got chemical ablation with ITIG and remains without sudden drop attack until fourteen months later. Tumarkin otolithic crisis is a life-threatening otologic emergency. What we have experienced in this case is that for the safety and quality of life of the patient who suffers from Tumarkin otolithic crisis, aggressive vestibular function ablation with high dose ITIG is necessary.
