Assessment of semicircular canal function in benign paroxysmal positional vertigo using the video head impulse test and caloric test

open access: yesLaryngoscope Investigative Otolaryngology, Volume 8, Issue 2, Page 525-531, April 2023., 2023
The VOR gain of vHIT in the affected canal was significantly smaller than that in the contralateral canal in p‐BPPV, but not in h‐BPPV. The caloric responses of the affected canal are reduced to a significantly larger extent in h‐BPPV compared to p‐BPPV.

Therapy-Resistant Atypical Downbeat Nystagmus with Vertigo Confined to Specific Head-Hanging Positions: Mapping to the Gravity Vector on a Multi-Axis Turntable

open access: yesCase Reports in Neurology, 2021
Downbeat nystagmus (DBN) observed in head-hanging positions, may be of central or peripheral origin. Central DBN in head-hanging positions is mostly due to a disorder of the vestibulo-cerebellum, whereas peripheral DBN is usually attributed to ...

Cupulolithiasis: A Critical Reappraisal

open access: yesOTO Open, Volume 7, Issue 1, January–March 2023., 2023
Abstract Objective To review the history and pathophysiologic theories for cupulolithiasis and canalith jam in benign paroxysmal positional vertigo. Data Sources PubMed, Google Scholar. Review Methods Three PubMed and Google Scholar searches were performed, keywords: “cupulolithiasis,” “apogeotropic [and] benign,” and “canalith jam,” resulting in 187 ...

The heterogeneity of mammalian utricular cells over the course of development

open access: yesClinical and Translational Medicine, Volume 12, Issue 10, October 2022., 2022
Single‐cell RNA‐seq identified several cell clusters in whole mouse utricle sensory epithelia from the neonatal period to adulthood. New HCs mainly differentiated from Sox9 progenitor cells, and only a few were produced by mitotic proliferation. Ubch10 cells could generate HCs mitotically in adulthood.

Vestibular Extremely Low‐Frequency Magnetic and Electric Stimulation Effects on Human Subjective Visual Vertical Perception

open access: yesBioelectromagnetics, Volume 43, Issue 6, Page 355-367, September 2022., 2022
Electric fields from both extremely low‐frequency magnetic fields (ELF‐MF) and alternating current (AC) stimulations impact human neurophysiology. As the retinal photoreceptors, vestibular hair cells are graded potential cells and are sensitive to electric fields. Electrophosphene and magnetophosphene literature suggests different impacts of AC and ELF‐

Immediate repeated testing (IRT) for BPPV: A cost‐effective examination

open access: yesLaryngoscope Investigative Otolaryngology, Volume 7, Issue 3, Page 832-834, June 2022., 2022
Abstract Objective To show that a negative Dix‐Hallpike test or Pagnini‐McClure test may convert into positive after head shaking in cases of semicircular canalith jam. Methods This is a retrospective study, where 768 cases of BPPV were studied of which 36 were found to have canalith jam.

Benign paroxysmal positional vertigo and vestibular impairment among older adults with dizziness

open access: yesLaryngoscope Investigative Otolaryngology, Volume 6, Issue 3, Page 488-495, June 2021., 2021
Abstract Objective This article aimed to investigate older adults visiting a geriatric institution for a bone density measurement who reported dizziness on a daily or weekly basis (but who are not seeking care for dizziness), according to BPPV, vestibular function, walking abilities, and frequency of falls.

Frequency of vateritic otoliths and potential consequences for marine survival in hatchery‐reared Atlantic salmon

open access: yesJournal of Fish Biology, Volume 98, Issue 5, Page 1401-1409, May 2021., 2021
Abstract Otoliths are inner‐ear structures of all teleost fish with functional importance for hearing and balance. The otoliths usually consist of aragonite, a polymorph of calcium carbonate, but may also take the form partly or entirely of vaterite, a different polymorph of calcium carbonate.

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]

open access: yes, 2011
Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.
