Abstract
OBJECTIVE The etiology of sudden sensorineural hearing loss (SSNHL) remains unknown; inflammation may be one cause. We retrospectively studied SSHNL cases in terms of the inflammatory parameters involved. METHODS We reviewed 169 SSNHL cases. The control group contained 132 patients with vocal cord polyps. The C-reactive protein (CRP) level, CRP/serum albumin (Alb) ratio, and neutrophil/lymphocyte ratio (NLR) were compared between the 2 groups. The relationships between these parameters and the time to treatment after SSHNL onset, hearing level, and therapeutic effects were also analyzed. RESULTS The CRP level, CRP/Alb ratio, and NLR were higher in SSNHL patients than in controls, but only the NLR differed significantly between the 2 groups. We found no significant differences between patients with different hearing levels, those evaluated at various times after SSNHL onset, and those with different outcomes. CONCLUSION The NLR is a reliable SSNHL diagnostic marker. The CRP level and CRP/Alb ratio are not useful indicators.

Abstract
Introduction: Sudden sensorineural hearing loss (SSNHL) manifests as an abrupt decline in hearing by at least 30 dB within a 3 day period. Intratympanic dexamethasone injection (ITDI) has gained recognition as a potential treatment for SSNHL. This study aims to investigate the efficacy of combining batroxobin with ITDI (Bat and ITDI) in treating SSNHL patients and its influence on peripheral blood inflammatory indicators. Methods: SSNHL patients were retrospectively categorized into the control group (treated with Bat) and the observation group (treated with Bat and ITDI). The study involved analyzing clinical baseline data, evaluating clinical efficacy, and comparing the total effective rates among SSNHL patients with different audiometric curve types in the observation group. Routine blood tests were performed on peripheral blood samples to calculate the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), and to determine C-reactive protein (CRP) levels. Adverse reactions and complications were closely monitored. Results: Following treatment, both groups displayed improvements in hearing, with the observation group exhibiting a significantly higher total effective rate (75.90%) than the control group (59.78%). For patients with 3 distinct types of sudden hearing loss (high-frequency, flat-frequency, total deafness), Bat and ITDI treatment demonstrated increased total effective rate for patients with different sudden hearing loss types (high-frequency, flat-frequency, and total deafness). Both groups experienced reduced peripheral blood CRP levels and the NLR/PLR values, with the observation group demonstrating lower values. Additionally, across the 4 audio metric subtypes, the levels of peripheral blood CRP, NLR, and PLR decreased in SSNHL patients, and the observation group had a lower incidence of adverse reactions compared to the control group. Conclusions: Bat and ITDI emerge as notably more effective for SSNHL patients, displaying potential for reducing peripheral blood inflammatory indicator levels and mitigating the incidence of adverse reactions or complications, thereby enhancing safety.

Abstract
(1) Background: A retrospective clinical study was conducted to compare the effectiveness of different pharmacological and non-pharmacological regimens for treating sudden sensorineural hearing loss (SSNHL). (2) Methods: Adult patients (n = 130) diagnosed with sudden sensorineural hearing loss (SSNHL) and hospitalized between 2015 and 2020 were enrolled in this study. Depending on the treatment regimen applied, patients were divided into five groups. Inclusion criteria were as follows: (i) hearing loss of sudden onset; (ii) hearing loss of at least 30 dB at three consecutive frequencies; (iii) unilateral hearing loss; (iv) age above 18 years. Exclusion criteria were as follows: (i) no follow-up audiogram; (ii) bilateral hearing loss; (iii) recognized alternative diagnosis such as tumor, disorder of inner ear fluids, infection or inflammation, autoimmune disease, malformation, hematological disease, dialysis-dependent renal failure, postdural puncture syndrome, gene-related syndrome, mitochondrial disease; and (iv) age below 18 years. (3) Results: Complete recovery was found in 14% of patients (18/130) and marked improvement was found in 6% (8/130), giving an overall success rate of 20%. The best results were obtained in the second group (i.e., patients given intratympanic glucocorticoid + prolonged orally administered glucocorticoid) where the success rate was 28%. In general, the older the patient, the smaller the improvement in hearing, a correlation that was statistically significant. (4) Conclusions: In treating SSNHL, the highest rate of hearing recovery-28%-was in the group of patients given intratympanic corticoid plus prolonged treatment with orally administered glucocorticoid.

Abstract
OBJECTIVE Sudden sensorineural hearing loss (SSNHL) is rare in pregnancy and can be attributed to pregnancy-induced changes in hormone levels that increase thrombogenic risk and alter cochlear microcirculation with consequent development of sudden deafness. The study aimed to analyze the risk factors associated with SSNHL in pregnant South Korean. METHODS A retrospective study of the incidence and risk factors associated with SSNHL before pregnancy enrolled 401,470 Korean women who delivered between January 2010 and December 2014. All participants underwent a pre-pregnancy national health screening examination through the National Health Insurance Corporation. We investigated the risk factors in 459 pregnant women with sudden sensorineural hearing loss and in 401,011 pregnant women without SSNHL through the pre-pregnancy national health screening examination and adverse perinatal outcome. RESULTS No statistically significant intergroup differences were observed in the maternal age, parity, method of delivery, gestational age at delivery, body mass index, blood pressure, as well as fasting blood glucose and cholesterol levels. After adjusting for maternal age, the pre-pregnancy body mass index was associated with an increased risk of sensorineural hearing loss in pregnancy (adjusted odds ratio 1.52, 95% confidence interval 1.04-2.22). The sensorineural hearing loss did not increase the risk for gestational hypertension, preterm birth (<37 weeks' gestation), small- and large-for-gestational-age infants, postpartum hemorrhage, placenta previa, and placental abruption. CONCLUSION SSNHL can occur throughout pregnancy and is associated with maternal pre-pregnancy obesity. Notably, it does not increase risks during delivery or cause adverse perinatal outcomes.

Abstract
This retrospective study investigated the use of electroacupuncture (EA) for the treatment of patients with sudden sensorineural hearing loss (SSNHL).Between May 2016 and April 2020, 140 patients with SSNHL were retrospectively analyzed. They were allocated to a treatment group (n = 70, received EA) and a control group (n = 70, received acupuncture). They received EA or acupuncture for a total of 3 months. The outcomes included average hearing threshold (AHT), tinnitus (as assessed by tinnitus handicap inventory [THI]), dizziness (as measured by dizziness handicap inventory [DHI]), and adverse events (AEs).After treatment, patients in both groups exerted more reduction in HT (P < .01), THI (P < .01), and DHI (P < .01), than those before the treatment. Furthermore, patients in the treatment group showed more relief in HT (P < .01), THI (P < .01), and DHI (P < .01), than those of patients in the control group. When it comes to AEs, both modalities had similar safety profile.The findings of this retrospective study indicated that the effectiveness of EA is superior to acupuncture in treating SSNHL. Future high quality studies are needed to warrant the present findings.

Abstract
Sensorineural deafness in mammals is most commonly caused by damage to inner ear sensory epithelia, or hair cells, and can be attributed to genetic and environmental causes. After undergoing trauma, many non-mammalian organisms, including reptiles, birds, and zebrafish, are capable of regenerating damaged hair cells. Mammals, however, are not capable of regenerating damaged inner ear sensory epithelia, so that hair cell damage is permanent and can lead to hearing loss. The field of epigenetics, which is the study of various phenotypic changes caused by modification of genetic expression rather than alteration of DNA sequence, has seen numerous developments in uncovering biological mechanisms of gene expression and creating various medical treatments. However, there is a lack of information on the precise contribution of epigenetic modifications in the auditory system, specifically regarding their correlation with development of inner ear (cochlea) and consequent hearing impairment. Current studies have suggested that epigenetic modifications influence differentiation, development, and protection of auditory hair cells in cochlea, and can lead to hair cell degeneration. The objective of this article is to review the existing literature and discuss the advancements made in understanding epigenetic modifications of inner ear sensory epithelial cells. The analysis of the emerging epigenetic mechanisms related to inner ear sensory epithelial cells development, differentiation, protection, and regeneration will pave the way to develop novel therapeutic strategies for hearing loss.

Abstract
Objective This study explored the relationship between macrophage migration inhibitory
factor (MIF) gene polymorphism (−173G/C) and glucocorticoid sensitivity in
sudden sensorineural hearing loss (SSNHL). Methods A total of 120 patients with SSNHL were divided into a
glucocorticoid-sensitive group and a glucocorticoid-resistant group. A group
of 93 healthy individuals served as the control group. Serum MIF levels of
the participants were measured and MIF genotyping was
performed. Results The frequency of the MIF −173C allele was significantly
higher in glucocorticoid-sensitive patients than in glucocorticoid-resistant
patients. Serum MIF levels were significantly higher in SSNHL patients than
in healthy controls, and higher in the glucocorticoid-sensitive group than
in the glucocorticoid-resistant group of SSNHL patients, which was
unexpected. Compared with patients with the GG genotype, patients with the
−173C allele (GC and CC genotypes) had significantly higher levels of serum
MIF and superoxide dismutase activity and lower levels of tumor necrosis
factor-α and malondialdehyde. Conclusion The MIF −173G/C polymorphism is associated with
glucocorticoid sensitivity in SSNHL patients. The C allele can result in
higher MIF production, reduced oxidative stress, and greater glucocorticoid
sensitivity.

Abstract
Autoimmune inner ear disease (AIED) is a rare, but treatable cause of sudden sensorineural hearing loss in children. Most cases present acutely and involve both ears. The precise mechanism of hearing loss in AIED is not known. Many suspected etiologies have been proposed including infections, vascular abnormalities, and trauma. However, 70% of cases are defined as idiopathic. There are no standardized diagnostic criteria for AIED, and the diagnostic process may be challenging. Positive auto antibodies and response to immunosuppressive therapy support the diagnosis. Treatment may include corticosteroids and steroid-sparing immunosuppressive medications. A high index of suspicion is recommended as the hearing loss may be stabilized or even reversed with early treatment. Long-term medical treatment failures generally have good outcomes with cochlear implantation. [Pediatr Ann. 2019;48(10):e391-e394.].

Abstract
Blocked Nose, Nosebleeds, Ringing in the Ear: ENT Diseases During Pregnancy Abstract. In this overview the clinical pictures of ear, nose and throat diseases and their symptoms, which occur frequently but also particularly during pregnancy, are presented. In addition, the respective therapy options in this partially vulnerable phase of mother and child are discussed. The primary principle is 'as much as necessary, but as little as possible'. Even if the complaints often disappear with the birth of the child, there may be considerable suffering of the pregnant woman and therapy may be necessary. Moreover, an adequate therapy should be applied with all ENT diseases, even for those not specifically associated with pregnancy.

Abstract
Recent years, the discussion about whether platelets participant in the development of sudden sensorineural hearing loss (SSHL) continues and many studies on the relationship between them have come to our attention. Some studies believe that platelet parameters have significantly changed in patients with SSHL, while some not, controversially. Therefore, to investigate the association between platelet parameters, including mean platelet volume (MPV), platelet distribution width (PDW) and platelet count (PLT), and SSHL, expecting to resolve controversy and provide clinical evidence for diagnosis and monitoring of SSHL. Basic methods: Literature was retrieved searching electronic databases (PubMed, Embase, Cochrane, and Scopus) and searching references of related articles by hand. A total of 18 case-control studies involving 1837/1734 subjects (SSHL/control) were included. Meta-analysis showed there was no difference between the patients who suffered SSHL and healthy controls in MPV level [standard mean difference (SMD) (95% confidence interval (CI)) = 0.16 (-0.07, 0.40), I2 = 80%, P<0.00001] and PLT [SMD (95% CI) = -0.03(-0.18, 0.12), I2 = 73%, P<0.00001]. While PDW exhibited significant difference [SMD (95% CI) = 0.85 (0.20, 1.49), I2 = 93%, P<0.00001]. Subgroup analysis about geographical area suggested PLT have obvious evidence for SSHL in Eastern country [SMD (95% CI) = 0.23 (0.14, 0.33), I2 = 0%, P=0.81]. Our study did not support a correlation between MPV and SSHL, while PLT may have clinical significance for SSHL in Eastern country. With insufficient data to explore the resource of heterogeneity for PDW, there is no decisive conclusion reached.

Abstract
Hearing loss is one of the most frequent health issues in industrialized countries. The pathogenesis and molecular mechanisms of hearing loss are still unclear. Histone deacetylases (HDACs) are emerging as key enzymes in many physiological processes, including chromatin remodeling, regulation of transcription, DNA repair, metabolism, genome stability and protein secretion. Recent studies indicated that HDACs are associated with the development and progression of hearing loss. Dysfunction of HDACs could promote the oxidative stress and aging in the inner ear. In light of considering the current stagnation in the development of therapeutic options, the need for new strategies in the treatment of hearing loss has never been so pressing. In this review, we will summarize the reported literatures for HDACs in hearing loss and discuss how HDAC family members show different performances for the possibility of process of diseases development. The possibility of pharmacological intervention on hearing loss opens a novel path in the treatment of hearing loss.

Ganesan P, Kothandaraman PP, Swapna S, Manchaiah V. A Retrospective Study of the Clinical Characteristics and Post-treatment Hearing Outcome in Idiopathic Sudden Sensorineural Hearing Loss. Audiol Res 2017; 7:168. [PMID: 28286637 PMCID: PMC5337819 DOI: 10.4081/audiores.2017.168] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2016] [Accepted: 01/02/2017] [Indexed: 01/01/2023] Open
Abstract
The purpose of this retrospective study was to analyze the clinical characteristics and document hearing recovery in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). 122 patients diagnosed with unilateral ISSNHL, from March 2009 to December 2014, were treated with oral steroids and pentoxifylline. Hearing change was evaluated by comparing pre-treatment and post-treatment pure-tone average (PTA) (500, 1K, and 2K Hz), and categorized into complete, partial, and no recovery of hearing. T-test, Wilcoxon Signed Rank test and Regression analysis were employed to analyze the statistical significance. Of the 122 patients, seventy-one (58%) had complete recovery and 34 (28%) had partial recovery. The average pre-treatment PTA was 78.3±16.9 dB whereas post-treatment average was 47.0±20.8 dB, showing statistically significant improvement (t=24.89, P≤0.001). The factors such as presence of tinnitus (P=0.005) and initial milder hearing loss (P=0.005) were found to be significant predictors for hearing recovery. Conventional steroid regimes produced a recovery rate in ISSNHL, which exceeds the spontaneous recovery rate. The current study results highlight the importance of medical treatment in the management of ISSNHL.

Abstract
Genetic polymorphisms in grainyhead‑like 2 (GRHL2) variants were examined for their suspected association with sudden sensorineural hearing loss (SSHL). Between January 2009 and April 2014, 190 patients with SSHL, who were diagnosed at the Departments of Otorhinolaryngology Head and Neck Surgery at Kaihua People's Hospital and Hangzhou First People's Hospital, were selected for the present study and defined as the SSHL group. A group of 210 healthy individuals were defined as the control group. Polymerase chain reaction (PCR)‑restriction fragment length polymorphism was used to detect GRHL2 genotypes, using genomic DNA isolated from peripheral blood as PCR templates. GRHL2 rs611419 genetic polymorphisms conferred a protective effect against SSHL (AT+TT vs. AA: OR=0.63, 95% CI=0.41‑0.98, P=0.038). In addition, rs10955255 polymorphisms were associated with a reduced risk of SSHL (AA vs. GG: OR=0.54, 95% CI=0.31‑0.95, P=0.032; GA+AA vs. GG: OR=0.58, 95% CI=0.38‑0.89, P=0.012). Combined genotypes of rs611419, rs10955255 and rs6989650 in the GRHL2 gene are also associated with a reduced risk of SSHL (P=0.035). In subjects who consumed alcohol, co‑occurrence of 3‑8 variant alleles conferred increased resistance to SSHL, compared with the occurrence of 0‑2 variant alleles (OR=0.40, 95% CI=0.21‑0.76, P=0.004). GRHL2 genetic polymorphisms, rs611419 and rs10955255, have a protective role against SSHL and reduce the risk of SSHL. However, rs6989650 is not associated with SSHL.

Abstract
CONCLUSION Sudden sensorineural hearing loss (SSNHL) in pregnancy is rare. It usually occurs in the third trimester. SSNHL in pregnancy does not increase risks during delivery or subsequent stroke. OBJECTIVES This study aimed to investigate the incidence and to determine the factors associated with SSNHL in pregnancy. METHOD Data were retrieved from Taiwan's National Health Insurance Database (NHIRD), covering the years 2000-2009. Patients admitted for SSNHL during pregnancy were enrolled. An age-matched controlled cohort was randomly selected from pregnant women without SSNHL in the NHIRD. The clinical characteristics of both cohorts were collected for further analyses. RESULTS Thirty-three patients with SSNHL in pregnancy were enrolled. The estimated incidence of SSNHL in pregnancy in Taiwan was 2.71 per 100,000 pregnancies. The incidence of SSNHL in pregnancy was lower than that of the general female population. The incidence of SSNHL in the third trimester was higher compared to the other two. The incidence of SSNHL occurring in the 30-39 years old age group was higher than other groups. Women with better socioeconomic status had a higher incidence of SSNHL. There were no identified systemic diseases before SSNHL. Two patients had pre-eclampsia and one patient had premature delivery. Nevertheless, SSNHL in pregnancy did not increase the risk for stroke.

Abstract
Background Sudden sensorineural hearing loss (SSNHL) is a relatively common condition that is usually of unknown etiology. A number of individual studies have investigated the association between various serum lipids and SSNHL; however, the findings have been inconsistent. In an attempt to obtain more definitive information on the relationship between serum lipids and SSNHL, we carried out a systematic review and meta-analysis. Methods Medline, the Cochrane Library, and EMBASE were searched using the following key words: lipid, cholesterol, triglyceride, fat, serum, blood, sudden hearing loss, hearing loss, hearing disorders. Randomized controlled trials, prospective cohort studies, and retrospective case-control studies involving patients with SSNHL and healthy controls that examined the relationship (reported as odds ratios [OR]) between lipid profiles and SSNHL were included. Primary outcomes were total cholesterol and low-density lipoprotein cholesterol (LDL-C) concentrations. Secondary outcomes were triglyceride, high-density lipoprotein cholesterol, and lipoprotein(a) concentrations. Results A total of 6 case-control studies were included in this systematic review/meta-analysis. The total number of participants ranged from 30 to 250 in the case group and from 43 to 271 in the control group. Meta-analysis revealed no significant difference in total cholesterol levels between the case and control groups (pooled OR = 1.79, 95% confidence interval [CI] = 0.98 to 3.26, P = 0.057). Likewise, meta-analysis revealed no significant difference in LDL-C concentrations between the case and control groups (pooled OR = 1.15, 95% CI = 0.64 to 2.07, P = 0.639). Since there were an insufficient number of studies reporting data for the secondary outcomes, meta-analysis was not possible. Conclusions Our results do not provide evidence for serum lipids being associated with SSNHL, nor do they definitively rule out such an association. Additional studies are needed to ascertain the relationship, or lack thereof, between serum lipids and SSNHL.

Abstract
Multiple sclerosis (MS) is a demyelinating disease and is considered the most debilitating neurological disorder among young adults. Sudden deafness has been reported in MS patients. This article describes cases of sudden deafness related to acute bouts in MS patients. A survey was conducted using 405 records of MS patients attended to at a reference center in the city of Rio de Janeiro between 2011 and 2012 to identify cases of sudden deafness. Seven patients were identified, 6 with a relapsing-remitting course and 1 with progressive disease at onset. Five patients had unilateral deafness and 2 bilateral. The recovery was complete in 4 and partial in 1, and there was no recovery in 2 patients. It was not possible to establish a topographical correlation between deafness and brainstem lesions. Audiometric examinations revealed severe hearing loss during the bout and recovery of hearing in 5 cases after remission.

Abstract
Sudden hearing loss is a rapid loss of neurosensory hearing that may occur within hours or days in an apparently healthy patient. Its origins are variable and multifactorial. Most patients do not recover hearing if not treated, and some even develop cophosis (deafness) in the affected ear. It is an otological emergency, as early therapeutic management offers a better hearing prognosis. As there is limited knowledge on this condition, it may be underdiagnosed in Primary Health Care Centers. It should be suspected in patients with abrupt hearing loss or tinnitus. Sophisticated instruments are not required for its diagnosis, just a detailed history, basic otoscopy, and proper interpretation of the hearing test. In this way, an accurate diagnosis is achieved in most cases, which is confirmed by audiometry.

Abstract
Objectives: The aim of this study was to establish the expression rate of autoimmunity in patients with sudden sensorineural hearing loss and to determine whether a positive marker is associated with a higher rate of hearing recovery after steroid treatment. Methods: A prospective study was performed on 137 patients who experienced sudden sensorineural hearing loss and underwent immunoserologic investigations. Autoantibodies evaluated on the day of admission included anti-double-stranded DNA, rheumatoid factor, antiphospholipid immunoglobulins G and M, antinuclear antibody, and complements C3 and C4. Results: Of 137 patients, 75 were male and 62 were female (mean age, 45.1 years). Hearing loss was found on the left side in 61 patients and on the right side in 76 patients. Elevation of at least 1 autoantibody or abnormal complement levels were found in 80 patients (58%), and abnormalities of 2 or more antibodies were found in 28 (20%). There were no statistically significant correlations between autoantibody abnormalities and age, initial hearing level, or positive treatment response. Conclusions: There is no clear evidence of a correlation between autoimmunity and hearing improvement in patients with autoantibody abnormalities. A high (but not significant) expression rate of autoantibody abnormality and complement level was seen in patients with sudden sensorineural hearing loss.
