Dear Colleagues,

It is my pleasure to invite you and members of your research group to submit an article for a Special Issue on “Positional Vertigo”.

At the beginning of the last century, Robert Bàràny studied positional nystagmus, remarking on its noticeable connection with gravitational forces. In 1950, Carl Olof Nylén classified and defined three main types of positional nystagmus: direction-changing, changing direction in different positions of the head; direction fixed, beating always to the same direction; and irregular, characterized by variations in its behavior. He stated, “The probability is that both the peripheral and central system are capable of giving rise to positional nystagmus”. Two years later, Dix and Hallpike detailed the characteristics of benign paroxysmal positional vertigo (BPPV) and developed the diagnostic maneuver for posterior canal benign paroxysmal positional vertigo. In the last 70 years the literature has been enriched with many works on positional vertigo, especially relating to BPPV. New variants, new diagnostic and therapeutic techniques, and new proposals to prevent recurrent BPPV have been described. However, positional vertigo is not exclusively BPPV. Positional vertigo has been observed in central nervous system disorders that can mimic BPPV, in inner ear disorders such as Meniere’s disease, and in neurological disorders involving the inner ear, such as migraine.

The scope of this Special Issue includes, but is not limited to:

• BPPV
  • New variants;
  • New approach strategies;
  • Therapeutic approach;
  • Prevention of recurrences, and vitamin D supplementation role;
  • Atypical forms;
  • Patients with poor/no response to the physical therapy;
• Pathophysiological mechanisms
  • Labyrintholithiasis, cupulolithiasis, and canalolithiasis;
  • Cupulopathy, light/heavy cupula;
• Central positional vertigo
  • Vascular disorders and neoplasms of the CNS;
  • Neurological disorders;
  • Autoimmune disorders;
• Recurrent positional vertigo in:
  • Menière;
  • Migraine;
  • New pathophysiological proposals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Audiology Research is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
