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.

Dizziness after Traumatic Brain Injury: Neurological Aspects: Young Seo Kim, Seon Jae Im, Hak Seung Lee; Res Vestib Sci. 2019;18(3):59-63. Published online September 15, 2019; DOI: https://doi.org/10.21790/rvs.2019.18.3.59

Abstract PDF: Vertigo, dizziness, and disequilibrium are common symptoms following concussion or traumatic brain injury. Dizziness and vertigo may be the result of trauma to the peripheral vestibular system or the central nervous system, or, in some cases, may be due to anxiety, depression, or posttraumatic stress disorder; these mechanisms are not mutually exclusive. While most peripheral vestibular disorders can be identified by testing and examination, those without inner ear causes that have persisting complaints of dizziness and motion sickness are more difficult to understand and to manage. Some of these patients exhibit features compatible with vestibular migraine and may be treated successfully with migraine preventative medications. This paper reviews the neurological causes of persisting dizziness, the possible mechanisms, and the pathophysiology, as a framework for patient management and for future research.

Dizziness in Traumatic Brain Injury: Visual-Vestibular Dysfunction, Neurotological Approach: Seong-Hae Jeong; Res Vestib Sci. 2019;18(2):27-31. Published online June 15, 2019; DOI: https://doi.org/10.21790/rvs.2019.18.2.27

Abstract PDF: Traumatic brain injury (TBI) could give rise to variable clinical manifestations based on the involved structures of our bodies. Although there are no structural abnormalities proven, the patients with mild TBI suffer from chronic dizziness and imbalance. Herein, I will discuss the visuo-vestibular interaction and neurotological finding in TBI, which could demonstrate the clue to the diagnosis and management in dizzy patients with TBI.

Injury Mechanism to Induce Traumatic Balance Disorder: Jeong Wook Kang, Jae-Yong Byun; Res Vestib Sci. 2019;18(1):1-7. Published online March 15, 2019; DOI: https://doi.org/10.21790/rvs.2019.18.1.1

Abstract PDF: Many of the dizziness patients annually visit ENT (ear, nose, throat) clinics because the vestibular function is the major organ to keep body balance and belongs to the Otorhinolaryngology. Nevertheless, many otolaryngologists feel that it is not easy to access the dizziness patients. The reason is that dizziness is not a final diagnosis and it is necessary to start the diagnosis of dizziness and find out the cause. Also, the causes of dizziness belong to multiple medical departments. That is why we need to pay more attention. Among them, traumatic vertigo can be manifested in various ways depending on the injury site and mechanism, and it is often difficult to predict the medical prognosis. Therefore, this review article focuses on traumatic vertigo. In this paper, we discussed its epidemiology and mechanism to help clinicians to treat patients with traumatic vertigo.

Posttraumatic Peripheral Vertigo: Soyeon Yoon, Mi Joo Kim, Minbum Kim; Res Vestib Sci. 2018;17(4):125-129. Published online December 21, 2018; DOI: https://doi.org/10.21790/rvs.2018.17.4.125

Abstract PDF: Posttraumatic vertigo can be defined as the vertiginous disorder occurred after head and neck trauma without other pre-existing vestibular disorder. Central, peripheral, and combined deficits might cause this condition. Especially, various peripheral vestibulopathies are possible causes of posttraumatic vertigo; benign paroxysmal positional vertigo, temporal bone fracture, perilymphatic fistula, labyrinthine concussion, posttraumatic hydrops, and cervical vertigo. Since the differential diagnosis of the posttraumatic vertigo is often difficult, it is essential to acquire knowledge of their pathophysiology and clinical features. In this review, peripheral vestibulopathy as the possible causes of posttraumatic vertigo were described according to the current literature.
