Rised sudden sensorineural hearing loss during COVID-19 widespread

Abstract

Background Sudden sensorineural hearing loss (SSNHL) is commonly encountered in otolaryngologic practice. SARS-CoV-2 infection is typically marked by respiratory symptoms although neurologic manifestations of the disease have also been described. Objective We want to measure the incidence and clinical aspects of persons exhibiting in otolaryngology clinic (OC) with SSNHL during the COVID-19 widespread and in the constant interval of previous year. Methods We retrospectively inspected the medical information for admissions to OC in Eskisehir, Turkey, during the COVID-19 widespread to describe the patients SSNHL. Clinical knowledge was saved for each subject and corresponded with that of SSNHL subjects demonstrating in 2019. Result Between 1 April and 30 September 2020, 68 patients admitted to OC for SSNHL; in 2019, there were 41 subjects, for an incidence rate ratio of 8.5 per 100.000 (95% CI 1.02–2.92) for the 2020 cohort. Of the 2020 group, forty-one patients (60.3%) presented with active or recent symptoms consistent with COVID-19 infection, compared with four (9.8%) in 2019 ( p < 0.001). Furthermore, subjects in 2020 group were younger (−15.5 years, p = 0.0141) than 2019 group and demonstrated prolonged interim (+1.7 days, p < 0.001) between SSNHL initiation and OC petition. Conclusion We detected increased incidence of SSNHL during the COVID-19 widespread compared to the same interval of the prior year; 60.3% of subjects confronting with SSNHL had signs that were harmonious with COVID-19 .

COVID-19 and Sudden Sensorineural Hearing Loss: A Systematic Review

“…Data from an Italian audiology tertiary referral center showed that the incidence of SSNHL and combined acute cochlear-vestibular involvement was significantly higher during the COVID-19 pandemic than in previous periods, with a more severe clinical presentation of pure-tone audiometry (PTA) ( 17 ). A study from Turkey found an increased incidence of SSNHL during the COVID-19 epidemic, with 60.3% of subjects having signs compatible with COVID-19 ( 18 ). A large tertiary hospital in China also found an increase in SSNHL visits to the outpatient and emergency departments during the COVID-19 pandemic compared to the past ( 19 ).…”

Sudden hearing loss and vestibular disorders during and before COVID-19 pandemic: An audiology tertiary referral centre experience

“…However, the ratio of diagnosis over the total patients evaluated was not very different between the two periods (1.91% vs 1.77%). Conversely, Fidan et al [14] , analysing a wider period (April 1st to September 30th 2020 versus 2019), reported an increased incidence of SSNHL during the COVID-19 pandemic. Notably, 57.4% of their patients tested positive for SARS-CoV-2 with nasopharyngeal swabs, strengthening the relationship between SSNHL and SARS-CoV-2 infection [15] , [16] .…”

Tinnitus, Sudden Sensorineural Hearing Loss, and Vestibular Neuritis As Complications of the Astra Zeneca COVID-19 Vaccine

“…Although more evidence is yet to be found, the temporal relation between the AZCV exposure and the appearance of hearing loss and tinnitus a few days after the vaccination in all cases clearly points toward a likely association between the vaccine and the otologic symptoms. Many authors have considered a possible link between COVID-19 infection and SSHL [2,[6][7][8][9][10]; however, as far as the author knows this is the first case series considering the possible association between a COVID-19 vaccine and inner ear damage, which could indeed have pathophysiology similar to that of the cases of SSHN secondary to COVID-19 infection. We display the audiometries of cases 1 and 5 since we believe them to be the most representative of the situation described by Tseng et al [12] (case 1) and the one described by Tsetsos et al [11] (case 5).…”

“…Several previous reports have mentioned the possible link between COVID-19 infection and inner ear damage [2,[6][7][8][9][10]; however to the authors´ very best knowledge this is the first case series considering the possible association between AZCV (or any COVID-19 vaccine) and inner ear damage, and so far only two previous isolated single case reports of auditory symptoms related to the AZCV have been described, including one report of SSHL itself [11], and one report of tinnitus presumably associated to cochleopathy secondary to the vaccine [12]. To our best knowledge, this is the first report of a patient with vestibular symptoms related to the AZCV.…”
