Abstract
BACKGROUND Sudden sensorineural hearing loss (SSNHL) is an abrupt loss of hearing, still idiopathic in most of cases. Several mechanisms have been proposed including genetic and epigenetic interrelationships also considering iron homeostasis genes, ferroptosis and cellular stressors such as iron excess and dysfunctional mitochondrial superoxide dismutase activity. RESULTS We investigated 206 SSNHL patients and 420 healthy controls for the following genetic variants in the iron pathway: SLC40A1 - 8CG (ferroportin; FPN1), HAMP - 582AG (hepcidin; HEPC), HFE C282Y and H63D (homeostatic iron regulator), TF P570S (transferrin) and SOD2 A16V in the mitochondrial superoxide dismutase-2 gene. Among patients, SLC40A1 - 8GG homozygotes were overrepresented (8.25% vs 2.62%; P = 0.0015) as well SOD2 16VV genotype (32.0% vs 24.3%; P = 0.037) accounting for increased SSNHL risk (OR = 3.34; 1.54-7.29 and OR = 1.47; 1.02-2.12, respectively). Moreover, LINE-1 methylation was inversely related (r2 = 0.042; P = 0.001) with hearing loss score assessed as pure tone average (PTA, dB HL), and the trend was maintained after SLC40A1 - 8CG and HAMP - 582AG genotype stratification (ΔSLC40A1 = + 8.99 dB HL and ΔHAMP = - 6.07 dB HL). In multivariate investigations, principal component analysis (PCA) yielded PC1 (PTA, age, LINE-1, HAMP, SLC40A1) and PC2 (sex, HFEC282Y, SOD2, HAMP) among the five generated PCs, and logistic regression analysis ascribed to PC1 an inverse association with moderate/severe/profound HL (OR = 0.60; 0.42-0.86; P = 0.0006) and with severe/profound HL (OR = 0.52; 0.35-0.76; P = 0.001). CONCLUSION Recognizing genetic and epigenetic biomarkers and their mutual interactions in SSNHL is of great value and can help pharmacy science to design by pharmacogenomic data classical or advanced molecules, such as epidrugs, to target new pathways for a better prognosis and treatment of SSNHL.

Abstract
Sudden sensorineural hearing loss (SSNHL) is defined as a sensorineural hearing loss of 30 dB or greater on at least three contiguous audiometric frequencies occurring within a 72 h period. Although SSNHL is commonly encountered in clinical audiology and otolaryngology practice, its etiopathogenesis continues to be poorly understood. Scientific investigations have highlighted the vulnerability of cochlear microcirculation to blood flow alterations. Even mild hypoperfusion can lead to immediate dysfunction in the organ of Corti, given the heightened susceptibility of cochlear hair cells to hypoxia and ischemic damage. The purpose of this review paper is to present evidence of endothelial and vascular involvement in SSNHL and the risk factors, such as metabolic syndrome, that may negatively impact the inner ear's vascular supply, influencing the onset pattern, incidence, and prognosis of SSNHL. By addressing these variables, we can deepen our comprehension of the mechanisms underlying SSNHL and potentially uncover strategies for prevention.

Abstract
BACKGROUND AND OBJECTIVES Tinnitus is one of the most common symptoms of sudden sensorineural hearing loss (SSNHL), with the incidence of tinnitus in patients with SSNHL ranging from 60% to 90%. Little is known, however, about the specific audiologic and hematologic factors that may be associated with the development of tinnitus. To better understand the relationship between tinnitus and SSNHL, the present study compared audiologic and hematologic factors in SSNHL patients with tinnitus and without tinnitus. SUBJECTS AND METHOD The present study compared 120 patients with SSNHL with tinnitus and 59 patients with SSNHL without tinnitus at their initial examination. Their audiology and hematologic test results were analyzed, and hearing recovery was determined by comparing the hearing thresholds before and after treatment. RESULTS 120 patients with tinnitus showed longer III and V latency in auditory brainstem response (ABR) tests, lower signal-to-noise ratios (SNR) at 2 kHz in transient evoked otoacoustic emissions (TEOAE) tests, and lower response rates at 2 kHz in distortion product otoacoustic emissions (DPOAE) tests of the affected ear (p < 0.05 each) than the 59 patients without tinnitus. However, there were no significant between-group differences in the mean hearing threshold and hearing recovery rate of the affected ear. Patients with tinnitus had significantly worse mean hearing thresholds and hearing thresholds at 4 kHz in the nonaffected ear. The percentages of monocytes and large unstained cells (%LUCs) were higher in the group without tinnitus (p < 0.05), although there were no significant between-group differences in inflammatory markers, such as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR). CONCLUSION Tinnitus accompanying SSNHL may be associated with baseline hearing level, as well as being an indicator of damage to outer hair cells and auditory nerves. Additional studies are needed to evaluate hematologic data in SSNHL patients with and without tinnitus.

Abstract
OBJECTIVES Sudden Sensorineural Hearing Loss (SSNHL) is an increasingly common health problem today. Although the direct mortality rate of this disorder is relatively low, its impact on quality of life is enormous; this is why accurate identification of pathogenesis and influencing factors in the disease process can play an essential role in preventing and treating the disease. Acute inflammation, which leads to chronic inflammation due to aberrant expression of inflammation-mediating genes, may play a significant role in the pathogenesis of the disease. The essential Nuclear factor kappa B (NF-kB) pathway genes, NFKB1 and NFKB2, serve as prothrombotic agents when expressed abnormally, compromising the cochlea by disrupting the endolymphatic potential and causing SSNHL. METHODS This study investigates the expression levels of NFKB1 and NFKB2 in peripheral blood (PB) through a quantitative polymerase chain reaction in 50 Iranian patients with SSNHL, and 50 healthy volunteers were of the same age and sex as controls. RESULTS As a result, NFKB2 expression levels in patients were higher than in controls, regardless of sex or age (posterior beta = 0.619, adjusted P-value = 0.016), and NFKB1 expression levels did not show significant differences between patients and controls. The expression levels of NFKB1 and NFKB2 had significantly strong positive correlations in both SSNHL patients and healthy individuals (r = 0.620, P = 0.001 and r = 0.657, P 0.001, respectively), suggesting the presence of an interconnected network. CONCLUSION NFKB2 has been identified as a significant inflammatory factor in the pathophysiology of SSNHL disease. Inflammation can play an essential role in developing SSNHL, and our findings could be used as a guide for future research.

Abstract
OBJECTIVE There was disagreement over the association between serum/plasma homocysteine (HCY) levels and sudden sensorineural hearing loss (SSNHL). Through the use of a meta-analysis, this study aims to determine whether there is a significant difference in serum homocysteine levels between the SSNHL group and the control group. DESIGN The Cochrane Library, EMBASE, and PubMed databases were all thoroughly searched. The two independent reviewers thoroughly examined the initially searched articles. The data results were calculated by standard mean difference (SMD) or odds ratios (OR). Review Manager (version 5.3) was applied to statistical data. STUDY SAMPLE There were 766 participants in the 6 trials with continuous outcomes that were part of the meta-analysis A. In addition, meta-analysis B, which included 961 people, contained a total of 3 studies with dichotomous results. RESULTS Both meta-analyses revealed the same conclusion that serum/plasma HCY levels in the SSNHL patients are higher than those in the controls (SMD 0.41, 95 % confidence interval (CI) 0.11 to 0.72, P < 0.01; OR 3.27, 95 % CI 2.16 to 4.94, P < 0.01). CONCLUSION This study demonstrated that the SSNHL patients' serum/plasma HCY levels were greater than those of the control group.

Abstract
BACKGROUND With the development of inner ear gadolinium imaging technology, its clinical application is more and more frequent. OBJECTIVES To explore the application value of inner ear MRI after intravenous gadolinium injection in sudden sensorineural hearing loss. MATERIAL AND METHODS The clinical data of 28 patients who were preliminarily diagnosed with sudden sensorineural hearing loss and the results of intravenous gadolinium MRI examination were analyzed to find the relationship between them. RESULTS Of the 28 patients (30 ears) with idiopathic sudden sensorineural hearing loss, 20 (71.4%) showed normal MRI. MRI abnormalities related to hearing loss were found in 8 cases (28.6%), of which 5 cases (17.9%) showed hydrops in the inner ear membrane labyrinth, 2 cases (7.1%) showed mastoiditis on the affected side, and 1 case (3.6%) showed vestibular schwannoma. CONCLUSIONS AND SIGNIFICANCE Inner ear MRI after intravenous gadolinium injection can be used as an index to detect the cause of sudden deafness, one of the factors to guide clinical treatment, and an important means to further explore the relationship between hydrops of membranous labyrinth and SSNHL.

Abstract
COVID-19 is a new pandemic infectious disease that emerged in Wuhan, China, at the end of 2019. We aimed to evaluate the sudden sensorineural hearing loss (SSNHL) prevalence after COVID-19 infection or even vaccination. This is a two-center retrospective, observational cross-sectional study performed at tertiary care referral Audiovestibular Medicine Units at the period between August 1, 2020, and October 31, 2021. All SSNHL patients diagnosed in a period of a month with COVID-19 or vaccinated with a COVID-19 vaccine were included in this study. Fifty-three cases with confirmed COVID-19 and one patient vaccinated with a COVID-19 vaccine 1 week before, who reported sudden sensory neural hearing loss, were included in this study. Forty-eight patients had unilateral hearing loss and 6 patients had bilateral hearing loss. Forty-nine patients had typical COVID-19 symptoms; one patient discovered them after complaining of anosmia and ageusia and one patient after COVID-19 vaccination; and three patients were complaining only from hearing loss and had a PCR test for nasopharyngeal swabs to prove infection. Different degrees of SSNHL ranged from mild to severe and most of the patients had severe hearing loss. With more patients, COVID-19 may be a potential factor in sudden sensorineural hearing loss. It should be kept in mind that SSNHL may be the only indicator used to identify COVID-19 cases.

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
The SARS-CoV-2 vaccination campaign is probably one of the most historic public hygiene measures in modern medicine. The drama of the pandemic has forced the scientific community to accelerate the development and commercialization of vaccines, thereby enhancing the phases of active surveillance. Among the adverse events following immunization (AEFI) reported, those of an audiovestibular interest, such as sudden sensorineural hearing loss (SSNHL), tinnitus, dizziness, and vertigo, constitute a very small percentage. There are many plausible etiological hypotheses, and scientific research needs to pay more attention to the correct collection of data, which up until now have often been inadequate and fragmented, on which to base future studies. SSNHL, new onset tinnitus, vertigo, and dizziness require a prompt evaluation, while the proposed treatment is the same as it is for events unrelated to vaccination. These are uncommon adverse events, and the risk rates for these diseases have not increased in conjunction with the COVID-19 vaccinations, therefore there is no justification of any hesitation towards the vaccination campaign.

Abstract
Background Sudden Sensorineural Hearing Loss (SSNHL) is a relatively rare symptom after immunisation from commonly used vaccines such as rabies, hepatitis B, measles and H1N1 and it could be an occasional symptom of COVID-19, even in mild manifestations of the disease. Case report We describe the case of a 57-year-old patient that reported SSNHL and tinnitus in his right ear 2 days after the inoculation of the Oxford-AstraZeneca (VAXZEVRIA) Covid-19 vaccine. The patient almost fully recovered after therapy and was referred to a long term follow-up program. Conclusion The current report underlines the importance to consider SSNHL as a possible rare adverse effect of the Covid-19 vaccine and take in account this possibility to promptly proceed with diagnosis and treatment of suspect cases.

Abstract
BACKGROUND Sudden sensorineural hearing loss (SSNHL) is acute and unexplained. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine in several inflammatory diseases. However, its role in SSNHL remains elusive. METHODS Lipopolysaccharide (LPS) was used to induce the inflammatory response of murine auditory cells, HEI-OC1. Silencing of MIF in HEI-OC1 cells was achieved by transfection of short hairpin RNA against MIF. 740Y-P and IMD0354 were used to stimulate the PI3K pathway and suppress the NF-κB pathway, respectively. RT-qPCR and western blotting were used to examine MIF and cyclooxygenase 2 (COX2) expression in LPS-treated HEI-OC1 cells. ELISA was employed to assess prostaglandin E2 (PGE2) concentrations. RESULTS MIF was upregulated in LPS-treated HEI-OC1 cells. MIF knockdown reduced PGE2 synthesis and COX2 expression in LPS-treated HEI-OC1 cells. Moreover, MIF knockdown suppressed activation of the PI3K/AKT and NF-κB pathway in LPS-treated HEI-OC1 cells. Additionally, inhibition of MIF decreased PGE2 production and COX2 expression via inactivation of the NF-κB pathway. CONCLUSION Inhibition of MIF alleviated LPS-induced inflammation in HEI-OC1 cells via inactivating the NF-κB signaling, which might provide a better understanding for SSNHL development.

Abstract
Background: There is growing evidence of otoneurological involvement of SARS-CoV-2, such as tinnitus and balance disorders and smell and taste disorders, but HL in COVID-19 patients has still been marginally studied. Investigating the role of SARS-CoV-2 as an aetiological factor of Sudden Sensorineural Hearing Loss (SSNHL) may offer the opportunity to address treatment strategies to maximize clinical recovery and avoid side effects. Methods and results: For this purpose, we will present case studies of five patients who experienced SSNHL during COVID-19. Patients were selected from COVID-19 positive adult subjects with mild clinical presentation, admitted to the outpatient Ear Nose and Throat Department of Cardarelli Hospital due to the onset of SSNHL during the infection. All underwent a complete audio-vestibular investigation before and after SSNHL treatment protocol. Each patient is described with a detailed analysis. Conclusions: SSNHL could be an occasional symptom of COVID-19, even in mild manifestations of the disease. Our experience leads us to underline the value of promptly recognizing and addressing this and other uncommon symptoms, giving patients the opportunity to receive early treatment.

Abstract
INTRODUCTION & OBJECTIVE The aim of the present study was to determine the efficacy of long-acting betamethasone, and its comparison with Dexamethasone as an intratympanic injection in the treatment of Sudden Sensorineural Hearing Loss (SSNHL). MATERIALS AND METHODS Thirty-one patients who do not respond to systemic steroids and poor prognosis patients were enrolled in this study. The patients divided randomly into two groups: 1- Dexamethasone and 2- Long acting betamethasone. Dexamethasone (0.4 ml/mg) or long-acting betamethasone (0.1 ml/mg) was slowly injected (0.4 to 0.6 cc) into the superior-anterior area of the tympanic membrane as 6 injections twice a week for a total of 3 weeks. Right after the treatment and one, two and six months after completion of treatment, an audiometry was performed and compared with the pre-injection values. RESULTS Speech Reception Threshold (SRT) showed improvements in both groups immediately after treatment and in the follow-up period, compared to baseline. Speech Discrimination Score (SDS) also improved in both groups directly after treatment and at one-month follow-up. The hearing improvement in the Dexamethasone group was clinically better than in the Beta group, but due to the non-parametric data, it was not possible to analyze the hearing improvement process in the variable group. CONCLUSION According to the results obtained in this study, intratympanic corticosteroid injection in the treatment of patients with SSNHL has positive and promising results on improving hearing level.

Abstract
OBJECTIVE/HYPOTHESIS The purpose of this review is to summarize evidence-based data regarding the ototoxic effects of potential COVID-19 therapeutics to treat patients suffering from SARS-CoV-2. METHODS Medications under investigation as novel therapeutics to treat COVID-19 were identified using the search term coronavirus therapeutics, COVID therapeutics, and SARS-CoV-2 therapeutics on ClinicalTrials.gov and the PubMed Database. A literature review was performed using the PubMed Database for each proposed COVID-19 therapeutic to identify relevant articles. Search criteria included Medical Subject Headings (MeSH) and key word search terms for ototoxicity, vestibulotoxicity, hearing disorders, and vertigo. RESULTS Six proposed COVID-19 therapeutics were identified as possessing ototoxic side effects including chloroquine and hydroxychloroquine, azithromycin, lopinavir-ritonavir, interferon, ribavirin, and ivermectin. CONCLUSIONS Available evidence suggests that ototoxic effects may be improved or mitigated by stopping the offending agent. Recognition of hearing loss, tinnitus, or imbalance/vertigo is therefore crucial to facilitate early intervention and prevent long-term damage. Hospitals should consider the inclusion of audiologic monitoring protocols for patients receiving COVID-19 therapeutics with known ototoxicity, especially in high-risk patient groups such as the elderly and hearing impaired.

Abstract
OBJECTIVE The association between sudden sensorineural hearing loss (SSNHL) and radiological findings of the vertebrobasilar artery is not well-known and little research has been done. We hypothesized that the radiological features of the vertebrobasilar artery contribute to the incidence and prognosis of SSNHL. METHODS We retrospectively enrolled patients diagnosed with unilateral SSNHL (SSNHL group) and those with acute vestibular neuritis (AVN; control group) in our hospital. All patients underwent magnetic resonance imaging and computed tomography. We measured the following parameters on the radiological images: basilar artery diameter, direction and distance of basilar artery deviation, direction and distance of vertebral artery deviation, and incidence of vertebral artery obstruction. Pure tone audiometry (PTA) was performed in all patients. Follow up PTA between 1 week and 1 month after treatment was performed in the SSNHL group. RESULTS A total of 244 SSNHL patients and 62 AVN patients were included in the analysis. Age, body mass index, and basilar artery diameter were found to be significantly associated with SSNHL. In the SSNHL group, patients were divided into three subgroups based on the consistency between the basilar artery deviation site and disease site. No significant difference was noted in initial PTA, final PTA, PTA recovery, and symptom improvement among the three groups. In case of the basilar artery, when the deviation and disease sites were in the opposite direction and the basilar artery diameter was >3.5 mm, diameter of basilar artery was positively correlated with PTA recovery. CONCLUSIONS The strength of this study is that radiological evaluation of the vertebrobasilar artery was performed. Further research on the association between SSNHL and radiological features of the vertebrobasilar artery should be conducted to emphasize the importance of vascular assessment in SSNHL.

Abstract
OBJECTIVES/HYPOTHESIS To examine the hearing outcomes of patients with sudden sensorineural hearing loss (SSNHL) treated with oral and intratympanic (IT) steroid only or a combination of steroid and migraine treatment. Our hypothesis was that adjuvant migraine medications may improve outcomes in SSNHL. METHODS A retrospective chart review at a tertiary otology center was conducted to identify patients with SSNHL who received oral steroid and IT dexamethasone injection(s) with or without migraine medications (a combination of nortriptyline and topiramate). RESULTS A total of 47 patients received oral steroid and IT dexamethasone injection(s) only, and 46 patients received oral steroid and IT dexamethasone injection(s) as well as migraine lifestyle changes plus a combination of nortriptyline and topiramate. There were no significant differences in demographics and baseline audiometric data between the two groups. Both groups demonstrated improvements in pure tone average (PTA) and hearing thresholds at 250 Hz and 8000 Hz posttreatment. However, compared to steroid-only group, the adjuvant migraine medications group had significantly greater improvements in hearing thresholds at the lower frequencies (250 Hz, 500 Hz, 1000 Hz). Patients in the latter cohort also had greater improvement in PTA (P = .01) and received fewer IT injections (P = .04) PTA improvement of ≥ 10 dB was observed in 36 patients (78%) in the adjuvant migraine medications group and 22 patients (46%) in the control group (P < .001). CONCLUSION In multimodal treatment of SSNHL, supplementing oral and IT steroid with migraine medications may result in greater improvements in lower frequency hearing thresholds and PTA. Furthermore, adjuvant migraine treatment can lead to decrease in number of IT injections, thus reducing procedure-related risks and complications.

Abstract
Aim of this paper is to investigate the presence of White Matter Lesions (WMLs) in subjects affected by Sudden Sensorineural Hearing Loss (SSNHL) and possibly to evaluate the significance of WMLs in SSNHL patients. A total of 64 patients (cases) affected by SSNHL were included in this case-control study. Hearing tests were performed at SSNHL onset, after 7 days and after 30 days. Cerebral MRI sequences were performed to rule out retrocochlear pathology, and WMLs were evaluated if present. MRI control group included 32 subjects, without hearing loss, affected by pituitary adenoma, who underwent cerebral MRI of follow-up. WML presence in those affected by SSNHL resulted having a similar distribution to that of the control group; however, we observed complete hearing recovery in 42,9% of patients without WML and in 11,6% of patients with WML >1 (p = 0,017*). The incidence of WML in patients with SSNHL was not different compared to that of the control group; however, MRI could have a prognostic role for SSNHL patients, as the presence of WMLs can been linked to a poorer hearing recovery rate.

Abstract
BACKGROUND Sudden sensorineural hearing loss (SSNHL) causes the loss of hearing of 30 dB or greater on at least three contiguous frequencies. It is known to be a multifactorial disease which the exact cause is unknown, rendering it as an idiopathic disorder of patients. AIMS/OBJECTIVES This study aims to shed further light on pathogenesis of this disease by studying the association between eNOS gene Glu298Asp polymorphism and VDR gene FokI polymorphism with SSNHL in Iranian population. MATERIAL AND METHODS This study involves a total of 77 cases and 100 controls, with patients inflicted with SSNHL categorized in case group and healthy subjects as control group. Genotyping of the VDR and eNOS genes was conducted by the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. RESULTS Our results showed a statistically significant association between genotype frequencies of eNOS gene Glu298Asp polymorphism in case group compared to healthy individuals in the control group (p = .01). Also, TT genotype was significantly the most prevalent genotype in case group in comparison to control group (TT vs GT + GG, OR = 3.5; 95% CI = 1.18-11.79). On the other hand, analysis of VDR gene FokI polymorphism frequencies showed no statistically significant association with SSNHL. CONCLUSIONS AND SIGNIFICANCE Our findings showed a significant association between the eNOS gene Glu298Asp polymorphism and SSNHL in the Iranian population; and "TT" genotype might be considered as a risk factor for SSNHL.

Abstract
OBJECTIVES A number of etiologies of idiopathic sudden sensorineural hearing loss (ISSNHL) have been proposed. Vascular disturbance is one cause of ISSNHL and has been reported to be associated with fibrinogen. We aimed to determine whether hyperfibrinogenemia is associated with poor outcome and whether a serial change in fibrinogen level is associated with outcome. METHODS Twenty-two patients with ISSNHL were enrolled. We compared the levels of fibrinogen in ISSNHL groups classified as improved and non-improved according to improvement of hearing. Blood samples were also collected from patients who visited the emergency room with coronary heart disease (CHD) as the control group. RESULTS Initial fibrinogen level was significantly different between the non-improved and improved ISSNHL group (350.63±87.20 vs. 310.71±81.06. The improved ISSNHL group showed a "surge phenomenon", in which fibrinogen started to decrease at day 5 and increased at day 26. In the non-improved group, fibrinogen remained elevated throughout the course of therapy. CONCLUSION It is important to measure not only the initial fibrinogen level but also to monitor its change throughout the course of therapy in order to predict the outcome of ISSNHL.
