Objective: The aim of this study is to evaluate the possible value of endolymphatic hydrops (EH) in patients with unilateral idiopathic sudden sensorineural hearing loss (UISSNHL) with four types according to audiometry.Methods: Seventy-two patients (40 men and 32 women; age range, 28–78 years; mean age: 50.0 ± 12.9 years) with UISSNHL were admitted retrospectively into this study. Based on the pure tone audiometry before treatment, the hearing loss of all these patients were categorized into four types: low-frequency group (LF-G), high-frequency group (HF-G), flat group (F-G), and total deafness group (TD-G). The average time from symptom onset to the first examination was 6.9 ± 4.4 days (1–20 days). 3D-FLAIR MRI was performed 24 h after intratympanic injection of gadolinium (Gd) within 1 week after the UISSNHL onset. The incidence of EH in the affected ears based on four types of hearing loss were analyzed using the Chi-square test, and the possible relationship with vertigo and prognosis were also assessed.Results: Eleven of 21 patients (52.4%) in LF-G had the highest EH-positive rate, followed by 18.2% in HF-G, 11.8% in F-G, and 17.4% in TD-G. The significant difference was found in the four groups (P = 0.018). The EH rate of LF-G was statistically significantly higher than that of F-G and TD-G (P = 0.009, P =0.014), respectively. After being valued by the volume-referencing grading system (VR scores), the EH level was represented by the sum scores of EH. In LF-G, no statistically significant difference was found in the prognosis of ISSNHL patients between with the EH group and the no EH group (P = 0.586). The symptom “vertigo” did not correlate with EH and prognosis.Conclusions: EH was observed in UISSNHL patients by 3D-FLAIR MRI. EH may be responsible for the pathology of LF-G but not related to prognosis. It might be meaningless to assess EH in other hearing loss types, which might be more related to the blood-labyrinth dysfunction.

To investigate the application of inner ear 3-dimensional fluid-attenuated inversion recovery (3D-FLAIR) magnetic resonance imaging (MRI) in patients with sudden sensorineural hearing loss (SSNHL) accompanied by inner ear hemorrhage. A total of 1252 SSNHL patients who were admitted from January 2010 to April 2018 were included in the study. The patients’ clinical features, complete blood counts, coagulation profiles, audiometry data, and MRI scans were retrospectively reviewed. Twenty-four patients had high labyrinth signals on inner ear 3D-FLAIR MRI (24/1252, 1.9%) that were diagnosed as inner ear hemorrhage. One patient had endolymphatic hydrops on the contralesional side. In the 24 patients, pure tone audiometry curves revealed profound deafness (19/24) and flat moderate hearing loss (5/24); most patients had associated vertigo (23/24) and tinnitus (19/24). Patients with SSNHL (N = 24) were treated. Sixteen patients had invalid improvement, 3 patients were markedly improved, 4 patients had effective treatment, and only 1 patient was cured, for a therapeutic efficacy of 33.3% (8/24). Follow-up 3D-FLAIR MRI in patients showed absorbance of labyrinthine hemorrhage and disappearance of the high signal intensity in the inner ear within 2 weeks to 4 months. Inner ear 3D-FLAIR MRI indicate that most cases of inner ear hemorrhage are spontaneous and that high labyrinth signals are absorbed within 4 months. The site of labyrinth hemorrhage is irregular and independent of hearing loss. Conventional treatment is not very effective, and an appropriate therapy for SSNHL requires further investigation.

Objective: The etiology of sudden sensorineural hearing loss (SSNHL) is still unknown. It has been demonstrated that normal endolymph metabolism is essential for inner ear function and that epithelial sodium channels (ENaC) may play an important role in the regulation of endolymphatic Na+. This study aimed to explore the potential association between αENaC p. Ala663Thr gene polymorphism and SSNHL.Methods: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to examine the genotype and allele frequency of the αENaC p. Ala663Thr polymorphism in 20 cases of low-frequency SSNHL (LF-SSNHL), 19 cases of high-frequency SSNHL (HF-SSNHL), 31 cases of all frequency SSNHL (AF-SSNHL), 42 cases of profound deafness SSNHL (PD-SSNHL), and 115 normal controls.Results: The T663 allele was found to be significantly associated with an increased risk of LF-SSNHL (p = 0.046, OR = 2.16, 95% CI = 1.01–4.62). The TT genotype and T663 allele, on the other hand, conferred a protective effect for PD-SSNHL (AA vs. TT: p = 0.012, OR = 0.25, 95% CI = 0.08–0.74; A vs. T: p = 0.001, OR = 0.36, 95% CI = 0.21–0.61). However, there was no statistically significant difference in genotype or allele frequency between the two groups (HF-SSNHL and AF-SSNHL) and the control group.Conclusion: The αENaC p. Ala663Thr gene polymorphism plays different roles in different types of SSNHL.

Abstract Objective The aim of this study was to compare the effectiveness of intratympanic (IT) steroid therapy and combined intravenous-cum-intratympanic (IVIT) steroid therapy in the management of sudden sensorineural hearing loss (SSNHL). Study Design This was a nonrandomized clinical trial. Setting Tertiary referral center. Patients Forty-four patients, who presented to the outpatient department or the emergency room and those who fulfilled the inclusion criteria, were enrolled in this study. The patients were put into two groups: Group IT—that received intratympanic steroid therapy alone and Group IVIT—that received intratympanic as well as intravenous steroid therapies. Intervention Therapeutic—in the form of IVIT steroid therapy. Main Outcome Measure Impact of the steroid therapy in patients with SSNHL was measured objectively with the help of pure tone audiometry (PTA). The improvement in hearing was assessed in terms of decibels gained after the intervention in both the groups. Results The mean improvement in PTA after 3 months in Group IT was 19.78 (±18.918) dB, whereas the mean improvement after 3 months in Group IVIT was 22.29 (±16.147) dB, statistically showing no significant difference between the groups. Conclusion The authors recommend the use of IT steroid therapy alone in the management of SSNHL.

AbstractObjectivesTo evaluate the plasma levels of endothelial cell-specific molecule-1 (ESM-1) and pentraxin-3 (PTX-3) in patients with idiopathic sudden sensorineural hearing loss, and to compare the pre- and post-treatment levels in patients responsive and non-responsive to therapy.MethodsThe study included 108 subjects: 51 with idiopathic sudden sensorineural hearing loss and 57 controls. For ESM-1 and PTX-3 analyses, blood samples were collected before and three months after treatment initiation in the idiopathic sudden sensorineural hearing loss group and once for the control group. Treatment response was evaluated three months after therapy initiation with pure tone audiometry, and the patients were divided into two groups: responsive and non-responsive to treatment.ResultsSerum ESM-1 levels were significantly higher in the idiopathic sudden sensorineural hearing loss group than the control group, whereas the difference was not significant for PTX-3. In the responsive and non-responsive groups, ESM-1 and PTX-3 levels were not statistically different before and after treatment.ConclusionTo our knowledge, this is the first study investigating plasma ESM-1 and PTX-3 levels in idiopathic sudden sensorineural hearing loss. Increased plasma ESM-1 levels may confirm endothelial dysfunction involvement in idiopathic sudden sensorineural hearing loss pathogenesis, which could be associated with vascular impairment.

Background Sudden sensorineural hearing loss (SSNHL) is an otologic emergency that warrants urgent management. Pure-tone audiometry remains the gold standard for definitively diagnosing SSNHL. However, in clinical settings such as primary care practices and urgent care facilities, conventional pure-tone audiometry is often unavailable. Objective This study aimed to determine the correlation between hearing outcomes measured by conventional pure-tone audiometry and those measured by the proposed smartphone-based Ear Scale app and determine the diagnostic validity of the hearing scale differences between the two ears as obtained by the Ear Scale app for SSNHL. Methods This cross-sectional study included a cohort of 88 participants with possible SSNHL who were referred to an otolaryngology clinic or emergency department at a tertiary medical center in Taipei, Taiwan, between January 2018 and June 2019. All participants underwent hearing assessments with conventional pure-tone audiometry and the proposed smartphone-based Ear Scale app consecutively. The gold standard for diagnosing SSNHL was defined as the pure-tone average (PTA) difference between the two ears being ≥30 dB HL. The hearing results measured by the Ear Scale app were presented as 20 stratified hearing scales. The hearing scale difference between the two ears was estimated to detect SSNHL. Results The study sample comprised 88 adults with a mean age of 46 years, and 50% (44/88) were females. PTA measured by conventional pure-tone audiometry was strongly correlated with the hearing scale assessed by the Ear Scale app, with a Pearson correlation coefficient of .88 (95% CI .82-.92). The sensitivity of the 5–hearing scale difference (25 dB HL difference) between the impaired ear and the contralateral ear in diagnosing SSNHL was 95.5% (95% CI 87.5%-99.1%), with a specificity of 66.7% (95% CI 43.0%-85.4%). Conclusions Our findings suggest that the proposed smartphone-based Ear Scale app can be useful in the evaluation of SSNHL in clinical settings where conventional pure-tone audiometry is not available.

Introduction: This study aimed to investigate the relationship between sudden sensorineural hearing loss, vestibular neuritis, and infection with COVID-19. Materials and Methods: In this study, a total of 56 Iranians (32 females and 24 males) with a Mean±SD age of 45.12±14 years were studied in Tehran City, Iran. Individuals diagnosed with Sudden Sensorineural Hearing Loss (SSNHL) or vestibular neuritis based on definitive diagnostic criteria were included in the study. The methodology comprised four sections of underlying Sudden Hearing Loss,, auditory and vestibular inspection, SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test, and statistical analysis. Also, the videonystagmography test was used in participants with vertigo to diagnose vestibular neuritis. Pure tone audiometry confirmed SSNHL in some patients with a complaint of hearing loss. Furthermore, tuning fork, Rinne and Weber tests were also performed. Results: The results of SARS-CoV-2 RT-PCR in 56 subjects showed that eight subjects (22.2%) with vestibular neuritis and two with SSNHL (10%) had a positive RT-PCR test. The Chi- square and Fisher exact-tests with a 95% confidence interval revealed no statistically significant (P>0.05) relationship between COVID-19 infection and vestibular neuritis or SSNHL. Conclusion: The present study showed no statistically significant relationship between audiovestibular disorders and positive SARS-CoV-2 RT-PCR test. However, the possibility of this relationship cannot be ruled out, and there is a need for studies with larger sample sizes.

Recent studies have identified sensorineural hearing loss as a possible manifestation of ankylosing spondylitis. We conducted a study of 30 patients with ankylosing spondylitis to characterize their audiologic profile and to correlate their disease activity and functional indices with their hearing thresholds. The study group was made up of 18 men and 12 women, aged 25 to 58 years (mean: 46.5), who were diagnosed with ankylosing spondylitis. We compared their findings with a socially and demographically matched group of 30 healthy controls. All 60 participants underwent an audiologic assessment, consisting of pure-tone audiometry, speech audiometry, and tympanometry. We used validated indices to assess disease activity and functional status, and we compiled information on the time of diagnosis and the types of medications used to treat the ankylosing spondylitis. We found that the average of the mean air-conduction thresholds at 0.5, 1, 2, and 4 kHz in the ankylosing spondylitis group was significantly worse than that of the controls (p = 0.004). A statistically significant difference was observed at frequencies greater than 3 kHz (p < 0.05). A subgroup of case patients who used only a tumor necrosis factor-alpha inhibitor exhibited better hearing thresholds than patients who used other drugs (p = 0.01). Differences in functional and disease activity scores between case patients with and without hearing loss were not statistically significant. We found that patients with ankylosing spondylitis did indeed have a greater prevalence of sensorineural hearing loss but that it was not correlated with either disease activity or functional status.

AbstractBackground:Sudden sensorineural hearing loss rarely occurs in patients with chronic myeloid leukaemia.Case report:We present a case report of a patient who presented with sudden sensorineural hearing loss as the first manifestation of chronic myeloid leukaemia, and review the mechanisms responsible for sudden sensorineural hearing loss in leukaemic patients.Results:A 31-year-old female presented to our clinic with unilateral sudden sensorineural hearing loss and tinnitus. Pure tone audiometry revealed profound sensorineural hearing loss in the left ear at all frequencies. During an investigation into her hearing loss, the patient was found to have chronic myeloid leukaemia.Conclusion:Every case of sudden sensorineural hearing loss must be carefully evaluated, and haematological disorders must be considered in the differential diagnosis of sudden hearing loss.
