Incidence of acute audio-vestibular disorders during the COVID-19 pandemic year and in the previous years: values and comparisons.

	PYP	FPYP	SPYP	PYP vs FPYP p-value	PYP vs SPYP p-value	PYP vs FPYP+ SPYP p-value
Incidence of total events	1.52%	1.31%	1.20%	0.479^a	0.288^a	0.309^a
Incidence of SSNHL	0.68%	0.49%	0.53%	0.318^a	0.422^a	0.295^a
Incidence of acute peripheral vestibular disorders	0.29%	0.52%	0.49%	0.160^a	0.200^a	0.143^a
Incidence of combined acute cochleo-vestibular disorders	0.54%	0.29%	0.17%	0.119^a	0.014^a	0.016^a
Incidence of SSNHL + combined acute cochleo-vestibular disorders	1.23%	0.78%	0.70%	0.078^a	0.035^a	0.022^a

Incidence was defined as the number of events in the target period divided by the number of total outpatient visits to the clinic in the same period (2761 in the PYP; 3446 in the FPYP, and 3407 in the SPYP, respectively).

Abbreviations: First Precedent Year Period (March 1st 2019 to February 29th 2020) FPYP; Pandemic Year Period (March 1st 2020 and February 28th 2021) PYP; Second Precedent Year Period (March 1st 2018 to February 28th 2019) SPYP; Sudden Sensorineural Hearing Loss SSNHL.
