OBJECTIVE: The purpose of this article is to describe BPPV in COVID-19 patients by discussing the possible mechanisms underlying the onset of this vertigo. METHODS: We studied eight patients (4 F, 4 M, aged between 44 and 69 years) with COVID-19 infections complaining of vertigo. Patients were evaluated at the end of infection with an accurate clinical history, and the investigation of spontaneous, positional and positioning nystagmus. RESULTS: The vestibular findings showed benign paroxysmal positional vertigo (BPPV) in all the patients. Three patients had a mild phenotype of the COVID infection, whereas five subjects were hospitalized for the COVID infection and in three cases intensive care was required. Vestibular evaluation showed an involvement of posterior semicircular canals in five patients and horizontal in three. Three patients were treated with the Epley maneuver, two with Semont, one with Lempert and two with Gufoni maneuvers. CONCLUSIONS: We hypothesize that BPPV in COVID-19 infections can be relate to drugs, prolonged bed rest and to direct damage by viral infection on the peripheral vestibular system and in particular on the otolitic membrane due to the cytopathic effect of the virus and to the inflammatory response. Studies on large series of patients are needed to confirm our preliminary observation and to better evaluate the pathophysiological mechanisms underlying BPPV in these patients.
