Özdemir O, Çelik R, Yiğit Ö. Sudden sensorineural hearing loss during the Covid-19 pandemic; experience of a tertiary referral center. Auris Nasus Larynx 2024; 51:853-858. [PMID: 39098105 DOI: 10.1016/j.anl.2024.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 07/16/2024] [Accepted: 07/18/2024] [Indexed: 08/06/2024]
Abstract
OBJECTIVE This study aimed to highlight the differences in the clinical management and treatment of sudden sensorineural hearing loss (SSNHL) due to the impact of the Coronavirus Disease 2019 (COVID-19) pandemic. METHODS This study compared patients diagnosed with SSNHL between March 2020 and March 2022, following the first reported case of COVID-19 in our country, with patients diagnosed between March 2018 and March 2020. The evaluation encompassed demographic characteristics, comorbidities, other ear-related complaints, hearing loss thresholds at each frequency, medical treatment administered, treatment duration, and post-treatment follow-up audiograms. RESULTS The demographic characteristics and comorbidities of patients before and during the pandemic showed similar distribution. There was no significant difference in the duration from the onset of symptoms to hospital admission during the pandemic compared to the previous period. When evaluating the treatment responses of hospitalized and treated patients according to Siegel's criteria during the pandemic, a similar trend to the pre-pandemic period was observed. It was noted that the use of systemic steroids and hyperbaric oxygen therapy decreased during the pandemic period, while the use of antivirals increased. CONCLUSIONS In our study conducted as a reference center, we want to emphasize that no clear data indicating a relationship between COVID-19 infection and NHL. Also, we believe that COVID-19 infection does not affect the course and prognosis of SSNHL.

Abstract
BACKGROUND This article presents a comprehensive review of data on the impact of facial palsy during the coronavirus disease 2019 (COVID-19) pandemic. The possible causes and pathophysiological mechanisms of changes in the epidemiology of facial palsy during the COVID-19 pandemic are also discussed. METHODS This multicenter retrospective cohort study included 943 patients diagnosed with Bell's palsy or Ramsay Hunt syndrome. This study compared patient demographics, comorbidities, symptoms, and treatments before the COVID-19 pandemic (from 2017 to 2019) and during the COVID-19 pandemic, from 2020 to 2022). RESULTS Following the COVID-19 outbreak, there has been a significant increase in the number of cases of Bell's palsy, particularly among elderly individuals with diabetes. Bell's palsy increased after the COVID-19 outbreak, rising from 75.3% in the pre-COVID-19 era to 83.6% after the COVID-19 outbreak. The complete recovery rate decreased from 88.2% to 73.9%, and the rate of recurrence increased from 2.9% to 7.5% in patients with Bell's palsy. Ramsay Hunt syndrome showed fewer changes in clinical outcomes. CONCLUSION This study highlights the impact of the COVID-19 pandemic on the presentation and management of facial palsy, and suggests potential associations with COVID-19. Notably, the observed increase in Bell's palsy cases among elderly individuals with diabetes emphasizes the impact of the pandemic. Identifying the epidemiological changes in facial palsy during the COVID-19 pandemic has important implications for assessing its etiology and pathological mechanisms of facial palsy disease.

Abstract
Background: Coronavirus disease 2019 (COVID-19) has been linked to Bell's palsy and facial paralysis. Studies have also shown increased risk of Bell's palsy in unvaccinated COVID-19 patients. Objective: To compare the relationship between Bell's palsy and COVID-19 infection and vaccination. Design: This is a retrospective longitudinal study. Methods: The COVID-19 research network was used to identify patients with facial palsy presenting to 70 health care organizations in the United States. The incidence of Bell's palsy was measured within an 8-week window after COVID-19 test or vaccination event in identified patients. Results: Incidence of facial palsy diagnosis (0.99%) was higher than the background rate within 2 months of COVID-19 infection. When compared with their negative counterparts, patients with COVID-19 infection had significantly higher risk of Bell's palsy (risk ratio [RR] = 1.77, p < 0.01) and facial weakness (RR = 2.28, p < 0.01). Risk ratio was also amplified when evaluating Bell's palsy (RR = 12.57, p < 0.01) and facial palsy (RR = 44.43; p < 0.01) in COVID-19-infected patients against patients who received COVID-19 vaccination. Conclusion: In our patient population, there is a higher risk of developing facial palsy within 2 months of COVID-19 infection versus vaccination. Vaccinated patients are not at higher risk of developing facial palsy.

[PMID: 38235010 PMCID: PMC10790126 DOI: 10.34172/hpp.2023.33] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 08/26/2023] [Indexed: 01/19/2024] Open
Abstract
Background Currently, there are few studies on the relationship between COVID-19 and the auditory system. In the current study, a review of the studies conducted in the fields of etiopathology, clinical manifestations, research, and treatment of hearing loss caused byCOVID-19 was conducted, which can be used as a baseline for future studies. Methods We utilized the research approach suggested by Arksey and O'Malley to carry out this scoping review. Search was conducted in Farsi and English with a focus on the onset of hearing loss in patients with COVID-19 through Medline and PubMed, and Google Scholar search engine. Studies included were those involving adult patients diagnosed with COVID-19 who experienced hearing loss, ear pain, ear discharge, and otitis media. Studies were eligible for inclusion if there was a description of the otologic dysfunction, specifically onset, duration, or clinical outcomes. Results Among 90 studies identified, 35 studies were included in the review process. Our findings suggest several possible mechanisms for sudden sensorineural hearing loss (SSNHL) in COVID-19 patients, and COVID-19 infection could have deleterious effects on the inner ear, specifically on the hair cells of the cochlea despite patients being asymptomatic and early identification of SSNHL in COVID-19patients can save the hearing and also patient. Conclusion Hearing loss in COVID-19 infection has not received much attention by health care professionals. Sensorineural hearing loss (SNHL), tinnitus, and/or vertigo have been shown to occur during and following COVID-19 infection. Due to lack of research studies, and the inconsistency and even contradictory of the findings, it remains questionable whether COVID-19 contributes to the high incidence of hearing loss. The proper understanding of the mechanisms behind hearing loss in COVID-19 infections needs further research. However, it seems likely that SNHL could be included among the manifestations of those-called "long COVID" syndrome.

Immun Inflamm Dis 2023; 11:e1108. [PMID: 38156388 PMCID: PMC10698807 DOI: 10.1002/iid3.1108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 11/04/2023] [Accepted: 11/18/2023] [Indexed: 12/30/2023] Open
Abstract
BACKGROUND Long coronavirus disease (COVID), characterized by persistent and sometimes debilitating symptoms following a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has garnered increasing attention as a potential public health crisis. Emerging evidence indicates a higher incidence of hearing loss in individuals who have had COVID 2019 (COVID-19) compared to the general population. However, the conclusions were inconsistent, and the causal relationship between COVID-19 and sensorineural hearing loss remains unknown. METHODS To addresses this outstanding issue, we performed Mendelian randomization analysis to detect the causal association between COVID-19 and hearing loss using the largest genome-wide association study data to date in the European population and confirmed the results in the East Asian population. Comprehensively sensitive analyses were followed, including Cochran's Q test, Mendelian randomization (MR)-Egger intercept test, MR-pleiotropy residual sum and outlier, and leave-one-out analysis, to validate the robustness of our results. RESULTS Our results suggested that there is no causal association between COVID-19 and the risk of hearing loss in the European population. Neither the susceptibility, hospitalization, and severity of COVID-19 on hearing loss (inverse variance weighted method: odds ratio (OR) = 1.046, 95% confidence interval (CI) = 0.907-1.205, p = .537; OR = 0.995, 95% CI = 0.956-1.036, p = .823; OR = 0.995, 95% CI = 0.967-1.025, p = .76). Replicated analyses in the East Asian population yielded consistent results. No pleiotropy and heterogeneity were found in our results. CONCLUSION In conclusion, our MR results do not support a genetically predicted causal relationship between COVID-19 and sensorineural hearing loss. Thus, the associations observed in prior observational studies may have been influenced by confounding factors rather than a direct cause-and-effect relationship. More clinical and mechanism research are needed to further understand this association in the future.

Abstract
BACKGROUND COVID-19 has been shown to affect the onset and severity of various diseases. We examined whether the clinical characteristics of Bell's palsy differed between before and during the COVID-19 pandemic. METHODS From January 2005 to December 2021, 1839 patients were diagnosed and treated for Bell's palsy at Kyung Hee University Hospital. These patients were divided into a pre-COVID period group and COVID-19 period group, and the clinical characteristics of the two groups were compared. RESULTS There were 1719 patients in the pre-COVID period group and 120 patients in the COVID-19 period group. There were no between-group differences in sex (p = 0.103) or in the presence of underlying hypertension (p = 0.632) or diabetes (p = 0.807). Regarding symptoms, there were no significant between-group differences in otalgia, dizziness, tinnitus, hyperacusis, or hearing loss (p = 0.304, p = 0.59, p = 0.351, p = 0.605, and p = 0.949). There were also no significant between-group differences in electroneurography results (p = 0.398), electromyography results (p = 0.331), House-Brackmann Grade at visit (p = 0.634), or recovery rate after treatment (p = 0.525). CONCLUSIONS Contrary to our expectation that Bell's palsy cases during the COVID-19 pandemic would show different clinical features than those occurring before COVID-19, the present study found no differences in clinical features or prognosis.

Abstract
OBJECTIVE To compare sudden sensorineural hearing loss (SSNHL) incidence rates over the coronavirus disease 2019 (COVID-19) outbreak and the COVID-19 vaccination campaign periods to pre-COVID-19 periods. STUDY DESIGN Retrospective cohort. SETTING Secondary hospital. PATIENTS Patients >12 years with auditory-confirmed SSNHL were enrolled. COVID-19 status and BNT162 inoculation records ≤28 days before SSNHL diagnosis were retrieved. Patients were categorized according to their date of presentation over four equal periods: 1) July 2018-April 2019 (first prepandemic period), 2) May 2019-February 2020 (second prepandemic period), 3) March 2020-December 2020 (COVID-19 outbreak), and 4) January 2021-October 2021 (BNT162b2 vaccinations campaign). INTERVENTIONS Pre- and post-COVID-19 emergence; BNT162b2 vaccine. MAIN OUTCOME MEASURES Incidence rate ratios (IRRs) were calculated to compare SSNHL cases during the COVID-19 and vaccination periods with pre-COVID-19 periods. RESULTS Of the 100 patients with SSNHL over the four periods, 1 had COVID-19 and 8 were vaccinated. The annual SSNHL incidence was 12.87, 12.28, 13.45, and 19.89 per 100,000 over periods 1 to 4, respectively. SSNHL incidence over the third period was not significantly different than the first/second periods (IRR = 1.045, 95% confidence interval [CI] = 0.629-1.85, ρ = 0.788, and IRR = 1.095, 95% CI = 0.651-1.936, ρ = 0.683, respectively), whereas SSNHL incidence rate over the fourth period was higher (IRR = 1.545, 95% CI = 0.967-2.607, ρ = 0.068, and IRR = 1.619, 95% CI = 1-2.73, ρ = 0.05, respectively). SSNHL incidence in vaccine recipients was lower than prepandemic unvaccinated patients (IRR = 0.584, 95% CI =0.464-1.67, ρ = 0.984, and IRR = 0.612, 95% CI =0.48-1.744, ρ = 0.92, respectively). CONCLUSION There were fewer SSNHL cases during the first COVID-19 months. Although the SSNHL rate over the COVID-19 vaccination campaign increased, it was not higher for patients who received the BNT162b2 vaccine.

Abstract
INTRODUCTION Accumulating data indicate that patients with COVID-19 could be affected by sudden sensorineural hearing loss (SSNHL). The aim of the study was to analyze the epidemiological and clinical trend of SSNHL occurrence during the COVID-19 pandemic by applying a systematic review and meta-analysis approach. METHODS PubMed, Scopus, Web of Science, ScienceDirect, and Cochrane databases were searched. RESULTS The seven included studies had adequate relevance to the topic and the quality was fair. The mean age at SSNHL onset ranged from 39.23 to 62.18 years during the pandemic year period (PYP); a meta-analysis of four studies comparing these data with those of previous periods in the same institutions found a younger age during the PYP (pooled mean -0.2848). The heterogeneity was high (76.1935%) and no frank asymmetry was observed in the funnel plot. The SARS-CoV-2 positivity rate of SSNHL patients ranged from 0% to 57.53%. Standard steroid treatments were applied without significant adverse effects. Comprehensively, hearing improvement was achieved for more than half of the cases. No studies reported long-term follow-up data. CONCLUSIONS Further prospective analyses on large series and a long-term follow up on COVID-related SSNHL cases are necessary to address the open questions regarding the causative link between COVID-19 infection and SSNHL.

Abstract
Sudden sensorineural hearing loss (SSNHL) is routinely encountered and is one of the most common emergent diseases in otolaryngology clinics. However, the etiology of SSNHL remains unclear. Due to the inaccessibility of the living human inner ear for biopsy, studies investigating the etiology of SSNHL have been performed by analyzing data obtained from examinations using peripheral blood or imaging. We updated the findings obtained from serological, magnetic resonance imaging, genetic, and viral examinations to reveal the etiology of SSNHL. Regarding viral examination, we focused on sensorineural hearing loss associated with coronavirus disease (COVID-19) because the number of correlated reports has been increasing after the outbreak. The updated findings revealed the following three possible mechanisms underlying the development of SSNHL: thrombosis and resulting vascular obstruction in the cochlea, asymptomatic viral infection and resulting damage to the cochlea, and cochlear inflammation and resulting damage to the cochlea. Thrombosis and viral infection are predominant, and cochlear inflammation can be secondarily induced through viral infection or even thrombosis. The findings about sensorineural hearing loss associated with COVID-19 supported the possibility that asymptomatic viral infection is one of the etiologies of SSNHL, and the virus can infect inner ear tissues and directly damage them.

Abstract
Objective To determine if otolaryngologists and audiologists of the American Academy of Otolaryngology – Head and Neck Surgery have noticed an increase in the incidence of sudden sensorineural hearing loss during the coronavirus disease 2019 pandemic. Methods A questionnaire was developed for the purpose of providing a cross-sectional descriptive analysis of perceived association between the coronavirus disease 2019 pandemic and an increase in the incidence of sudden sensorineural hearing loss. Results Of respondents, 63.0 per cent did not notice an increase in sudden sensorineural hearing loss during the coronavirus disease 2019 pandemic. There was a weak positive correlation between patients identified with sudden sensorineural hearing loss and the percentage of coronavirus disease 2019 positive patients reported by each medical care provider (Spearman correlation = 0.20, 95 per cent confidence interval = 0.05–0.33). There was no association between geographical location and perceived increase in sudden sensorineural hearing loss (p = 0.38). Conclusion The majority of respondents did not perceive an increase in the incidence of sudden sensorineural hearing loss during the coronavirus pandemic, regardless of geographical region.

Abstract
A growing body of evidence suggests that patients with the 2019 Coronavirus disease (COVID-19) have a risk of developing sudden sensorineural hearing loss (SSNHL). The pathogenesis of COVID-19-related SSNHL remains unclear. This systematic review examined whether COVID-19 causes an increased incidence of SSNHL and the clinical characteristics of patients with COVID-19-related SSNHL according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. SSNHL usually developed between a few days and 2 months after the diagnosis of COVID-19, and a proportion of patients developed it before the diagnosis of COVID-19. The literature is inconsistent regarding whether COVID-19 causes an increased incidence of SSNHL, and this matter remains unclear. This review included 23 patients with COVID-19-related SSNHL, all adult patients with an average age of 43.1 years. Of these patients, 60.9% had accompanying tinnitus symptoms. Glucocorticoids are the preferred medication to treat COVID-19-related SSNHL. Intratympanic administration may be considered to reduce the side effects of the drug. Hearing tests are suggested when hearing loss is suspected in COVID-19 individuals, and if SSNHL is detected, prompt and aggressive treatment is vital. Large-scale, multicenter research on the pathophysiology, treatment, and prognosis of COVID-19- related SSNHL should be conducted in the future.

Abstract
BACKGROUND The aetiology of idiopathic facial nerve palsy (Bell's palsy, BP) and sudden sensorineural hearing loss (SSNHL) are not known. It has been proposed that common respiratory tract viruses play a part in the pathophysiology of these diseases. OBJECTIVES The incidence of many infectious diseases decreased during the lockdown of the society that took place during the COVID-19 pandemic. We investigated a possible change in the incidence of BP and SSNHL during the lock-down. MATERIAL AND METHODS We searched the patient records for all BP and SSNHL cases between 1 Jan 2017 - 31 Aug 2020 at the hospital district of Helsinki and Uusimaa that covers a population of about 1.2 million. RESULTS The mean monthly incidence on BP decreased during the COVID-19 pandemic lock-down. No change in the SSNHL incidence was discovered. CONCLUSIONS AND SIGNIFICANCE There is reason to speculate that one aetiologic reason for BP are transmittable respiratory tract pathogens.

Abstract
Background Numerous infections can result in neurological symptoms, including anosmia, facial paralysis, and abrupt sensorineural hearing loss (SSNHL). During the earlier SARS pandemic, coronaviruses were linked to a loss of smell and taste due to brain damage. Purpose To clinically detect corticosteroid treatment effectiveness in SSNHL post-COVID-19 infection and to detect the factors that affect the prognosis for these patients for better diagnosis and earlier management. Subjects and method Subjects included 20 subjects diagnosed by PCR as COVID-19 virus positive, complaining of sudden onset hearing loss post viral infection in different durations. All subjects had basic audiological evaluation done pre-treatment and repeated after 1 week, 2 weeks, and 1 month after treatment with methylprednisolone 21-acetate tablets. Results Onset of hearing loss post-COVID infection ranged from 1 to 3 months. As regards the improvement recognized with treatment course, thirteen patients (65%) of all twenty patients showed complete improvement at 1 month after starting treatment, and seven patients (35%) showed no improvement even after 1 month. Conclusion SSNHL has been widely recognized in the context of COVID-19 to date. Early corticosteroid therapy could help in the recovery of hearing, especially if the beginning of therapy was early in the first 2 weeks.
