Abstract
BACKGROUND Idiopathic sudden sensorineural hearing loss is a disabling condition that lowers the quality of life specifically in older adults living alone. It is crucial to determine the outcome of the disease and to offer early treatment to prevent isolation caused by hearing impairment in this population. The objective of our study was to investigate whether the initial cochlear nerve thickness may predict the outcome of hearing recovery in older adults with idiopathic sudden sensorineural hearing loss. METHODS The study population was composed of older adults that were referred with idiopathic sudden sensorineural hearing loss in 1 ear. Long-term audiological data of the cohort were analyzed according to Siegel's criteria on hearing recovery and were grouped according to complete recovery or treatment failure. Cochlear nerve diameters of the diseased and safe ears of each group, measured on reformatted images on magnetic resonance imaging, at the fundus, in the mid-internal acoustic canal, and at the entry point into the Pons were compared in each group and between groups. RESULTS Mean cochlear nerve diameter was significantly larger in the recovered older adults (1.11 ± 0.27 mm) than in the non-recovered adults (0.94 ± 0.21 mm) at the mid-internal acoustic canal (Student's t-test, P < .05). Cochlear nerve thickness at mid-internal acoustic canal (≤0.8 mm) sensitivity for recovery failure was 89% and displayed an odds ratio 5.333, 95% CI (1.000-28.435). CONCLUSION Cochlear nerve thickness in mid-internal acoustic canal in non-recovered older adults with idiopathic sudden sensorineural hearing loss is significantly thinner than the completely recovered group. Older adults with mid-internal acoustic canal cochlear nerve greatest diameter cutoff level of ≤0.8 mm are 5.33 times more exposed to recovery failure.

The functional status of vestibular otolith and conductive pathway in patients with unilateral idiopathic sudden sensorineural hearing loss. Front Neurol 2023; 14:1237516. [PMID: 37545733 PMCID: PMC10399741 DOI: 10.3389/fneur.2023.1237516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 07/03/2023] [Indexed: 08/08/2023] Open
Abstract
Background The cause of idiopathic sudden sensorineural hearing loss (ISSNHL) remains unknown. It has been found that the functional status of the vestibular otolith is relevant to its prognosis; however, the evaluation of the vestibular otolith (intra-labyrinth) and superior and inferior vestibular nerve pathways (retro-labyrinth) in ISSNHL patients is not well-documented. Objective This study aimed to investigate the functional status of the vestibular otolith and conductive pathway in patients with unilateral ISSNHL and analyze the correlations between vestibular evoked myogenic potentials (VEMPs) and hearing improvement after treatment. Methods A total of 50 patients with unilateral ISSNHL underwent a battery of audio-vestibular evaluations, including pure tone audiometry, middle ear function, air-conducted sound-cervical VEMP (ACS-cVEMP), ACS-ocular VEMP (ACS-oVEMP), galvanic vestibular stimulation-cervical VEMP (GVS-cVEMP), and GVS-ocular VEMP (GVS-oVEMP). The results of auditory and VEMPs were retrospectively analyzed. Results The abnormal rates of ACS-cVEMP, ACS-oVEMP, GVS-cVEMP, and GVS-oVEMP in affected ears were 30, 52, 8, and 16%, respectively. In affected ears, the abnormal rate of ACS-oVEMP was significantly higher than that of ACS-cVEMP (p = 0.025), while it was similar between GVS-cVEMP and GVS-oVEMP (p = 0.218). Compared with GVS-cVEMP, affected ears presented with a significantly higher abnormal rate of ACS-cVEMP (p = 0.005), and the abnormal rate of ACS-oVEMP was significantly higher than that of GVS-oVEMP (p < 0.001). No significant difference existed in latency and amplitude between affected and unaffected ears in ACS-VEMPs or GVS-VEMPs (p > 0.05). The abnormal rate of VEMPs in the poor recovery group was significantly higher than that of the good recovery group (p = 0.040). The abnormality percentages of ACS-oVEMP and GVS-oVEMP in the poor recovery group were significantly higher than that of the good recovery group (p = 0.004 and 0.039, respectively). The good hearing recovery rates were 76.47% in the normal VEMPs group, 58.33% in the intra-labyrinth lesion group, and 22.22% in the retro-labyrinth lesion group. Hearing recovery worsened as a greater number of abnormal VEMPs was presented. Conclusion Besides Corti's organ, the impairment of otolithic organs was prominent in patients with ISSNHL. The normal VEMPs group had the highest rate of good recovery, followed by the intra-labyrinth lesion group and the retro-labyrinth lesion group presented with the lowest recovery rate. Abnormalities in ACS-oVEMP and/or GVS-oVEMP were indicators of a poor prognosis.

Abstract
We aimed to characterize the clinical profiles and short-term outcomes of adult patients with full-frequency idiopathic sudden sensorineural hearing loss (ISSNHL) treated uniformly with combination therapy, and to determine the prognostic predictors for the combination therapy. A total of 131 eligible cases hospitalized in our department from January 2018 to June 2021 were retrospectively reviewed. All enrolled cases received a standardized combination therapy employing intravenous methylprednisolone, batroxobin, and Ginkgo biloba extract during the 12 days of hospitalization. The clinical and audiometric profiles were compared between recovered patients and their unrecovered counterparts. The overall recovery rate was 57.3% in the study. Accompanying vertigo (odds ratio = 0.360, p = 0.006) and body mass index (BMI, odds ratio = 1.158, p = 0.016) were two independent predictors of hearing outcomes of the therapy. The male gender and cigarette-smoking history were marginally associated with good hearing prognosis (p = 0.051 and 0.070, respectively). Patients with BMI ≥ 22.4 kg/m2 had a better chance of hearing recovery (p = 0.02). Conclusions: Accompanying vertigo and low BMI (<22.4 kg/m2) were independently associated with poor prognosis for full-frequency ISSNHL in combination therapy. Male gender and cigarette-smoking history might be considered positive effects on hearing prognosis.

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.

Vestibular assessment in sudden sensorineural hearing loss: Role in the prediction of hearing outcome and in the early detection of vascular and hydropic pathomechanisms. Front Neurol 2023; 14:1127008. [PMID: 36873440 PMCID: PMC9975513 DOI: 10.3389/fneur.2023.1127008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 01/30/2023] [Indexed: 02/17/2023] Open
Abstract
Introduction Predicting hearing outcome in sudden sensorineural hearing loss (SSNHL) is challenging, as well as detecting the underlying pathomechanisms. SSNHL could be associated with vestibular damage since cochleo-vestibular structures share the same vascularization, along with being in close anatomical proximity. Whereas viral inflammations and autoimmune/vascular disorders most likely represent the involved aetiologies, early-stage Menière's disease (MD) can also present with SSNHL. Since an early treatment could beneficially influence hearing outcome, understanding the possible etiology plays a pivotal role in orienting the most appropriate treatment. We aimed to evaluate the extent of vestibular damage in patients presenting with SSNHL with or without vertigo, investigate the prognostic role of vestibular dysfunctions on hearing recovery and detect specific lesion patterns related to the underlying pathomechanisms. Methods We prospectively evaluated 86 patients with SSNHL. Audio-vestibular investigation included pure-tone/speech/impedance audiometry, cervical/ocular-VEMPs, vHIT and video-Frenzel examination. White matter lesions (WML) were evaluated on brain-MRI. Patients were followed-up and divided into "SSNHL-no-vertigo," "SSNHL+vertigo" and "MD" subgroups. Results Hearing was more impaired in "SSNHL+vertigo" patients who exhibited either down-sloping or flat-type audiograms, and was less impaired in "MD" where low frequencies were mostly impaired (p < 0.001). Otolith receptors were more frequently involved than semicircular canals (SCs). Although the "SSNHL-no-vertigo" subgroup exhibited the lowest vestibular impairment (p < 0.001), 52% of patients developed otolith dysfunctions and 72% developed nystagmus. Only "MD" subjects showed anterior SC impairment and upbeating spontaneous/positional nystagmus. They more frequently exhibited cervical-VEMPs frequency tuning (p = 0.036) and ipsilesional spontaneous nystagmus (p < 0.001). "SSNHL+vertigo" subjects presented with more frequently impaired cervical-VEMPs and posterior SC and with higher number of impaired receptors (p < 0.001). They mainly exhibited contralesional spontaneous and vibration-induced nystagmus (p < 0.05) and only they showed the highest WML score and "vascular" lesion patterns (p < 0.001). Concerning the outcomes, hearing was better in "MD" and worse in "SSNHL+vertigo" (p < 0.001). Hearing recovery was mostly affected by cervical-VEMPs impairment and the number of involved receptors (p < 0.05). Patients with "vascular" lesion patterns presented with the highest HL degree and WML score (p ≤ 0.001), while none of them exhibited a complete hearing recovery (p = 0.026). Conclusions Our data suggest that vestibular evaluation in SSNHL can provide useful information on hearing recovery and underlying aetiologies.

[PMID: 36203999 PMCID: PMC9530985 DOI: 10.3389/fneur.2022.976393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 08/29/2022] [Indexed: 11/13/2022] Open
Abstract
Idiopathic sudden sensorineural hearing loss (ISSNHL) is an emergency ear disease that is referred to as a sensorineural hearing loss of at least 30 dB in three sequential frequencies and occurs over a period of < 72 h. Because of its etiology, pathogenesis, and prognostic factors, the current treatment methods are not ideal. Previous studies have developed prognostic models to predict hearing recovery from ISSNHL, but few studies have incorporated serum biochemical indicators into previous models. The aim of this study was to explore the factors influencing the ISSNHL prognosis of combination therapy (combined intratympanic and systemic use of steroids, CT), among the patient population data, the serum biochemical indicators before the treatment, and the clinical features of ISSNHL. The new prediction model was developed through these factors. From November 2015 to April 2022, 430 patients who underwent CT at the Department of Otorhinolaryngology Head and Neck Surgery, Tangdu Hospital, Air Force Medical University for ISSNHL, were reviewed retrospectively. We found significant differences in age (P = 0.018), glucose (P = 0.035), white blood cell (WBC) (P = 0.021), vertigo (P = 0.000) and type (P = 0.000) with different therapeutic efficacies. Multivariate logistic regression analysis showed that age (OR = 0.715, P = 0.023), WBC (OR = 0.527, P = 0.01), platelet to lymphocyte ratio (PLR) (OR = 0.995, P = 0.038), vertigo (OR = 0.48, P = 0.004), course (time from onset to treatment) (OR = 0.681, P = 0.016) and type (OR = 0.409, P = 0.000) were independent risk factors for ISSNHL prognosis. Based on independent risk factors, a predictive model and nomogram were developed to predict hearing outcomes in ISSNHL patients. The area under the curve (AUC) value of the model developed in this study was 0.773 (95% CI = 0.730–0.812), which has a certain predictive ability. The calibration curve indicated good consistency between the actual diagnosed therapeutic effectiveness and the predicted probability. The model and nomogram can predict the hearing prognosis of ISSNHL patients treated with CT and can provide help for medical staff to make the best clinical decision. This study has been registered with the registration number ChiCTR2200061379.

Abstract
PURPOSE The aim of the study was to assess a correlation between MRI labyrinthine changes detected with IV-gadolinium optimized high-resolution 3D-FLAIR sequences 4 h after injection (OPT4-3DFLAIR) and the type of SSNHL, in terms of frequency alteration and severity. METHODS This was a prospective monocentric study achieved from July 2019 to December 2020. The inclusion criterion was acute hearing loss of at least 30 dB over three contiguous frequencies occurring within a 72-h period, documented by a pure-tone audiometry (PTA). The primary endpoint was the visual assessment of hyperintensity in labyrinthine structures on OPT4-3DFLAIR performed on 3T MRI. RESULTS Thirty-six affected ears were included (20 men, 15 women; mean age: 54.5 ± 16.3 years) with 69.4% full-spectrum hearing loss. The median hearing loss, expressed as median and interquartile range [IQR] was 91 dB [74-120], with 47.2% of concomitant acute vestibular syndrome. Pathological signal was found in 26 out of 36 ears (72.2%). Basal turn enhancement was found in all abnormal MRIs, with 73.1% of apical turn enhancement and 50% of vestibular enhancement. Seventeen on 19 cases (89.5%) with apical involvement on MRI had low-frequency hearing loss. Vestibular involvement on MRI was significantly associated with a wider frequency range of hearing loss (p = 0.0002) and the severity of SSNHL (84.5 [71.7-92.5] dB versus 120 [85.8-120] dB, p = 0.0158). CONCLUSION This report shows that in pathological MRI in SSNHL, a pathologic cochlear base signal is always detected, a cochlear apical turn enhancement matches with low-tone impairment, and a pathological signal within the posterior labyrinth is associated with an impairment of all frequencies and the severity of SSNHL.

Abstract
The causes of sudden sensorineural hearing loss (SSNHL) are unclear, and the condition cannot be treated with specific regimens. The present study was designed to explore the effects of alprostadil combined with hyperbaric oxygen (HBO) on hearing recovery and hemorheology in patients with SSNHL, and to analyze factors influencing treatment efficacy. in total, 104 patients with SSNHL were enrolled between January 2015 and July 2018 in a randomized controlled trial. Group A (n=52) received alprostadil treatment and Group B (n=52) were treated with HBO plus alprostadil. Following treatment, the overall recovery rates of tinnitus, aural fullness and vertigo in Group B were significantly higher than those in Group A (P<0.05). Low-, middle- and high-shear whole blood viscosity and whole blood viscosity in the two groups significantly decreased, and those in Group B were significantly lower than those in Group A (P<0.05). The present results indicated that the combination of alprostadil with HBO can improve the therapeutic effect on SSNHL, reduce blood viscosity and improve coagulation function, thus significantly promoting hearing recovery. Further, SSNHL treatment efficacy was influenced by age, time of onset, hearing threshold, presence or absence of tinnitus, plasma viscosity and serum C-reactive protein levels. The trial registration number for the present study was: NCT02563872.

Abstract
INTRODUCTION Sudden sensorineural hearing loss (SSNHL) is a therapeutic challenge. There are several controversies regarding the management protocol of SSNHL. This study aimed to present the results of a novel treatment algorithm, which is a combination of systemic steroids and a tapering intratympanic (IT) dexamethasone regimen. MATERIALS AND METHODS The past 10 years' medical records of idiopathic SSNHL cases in Ghaem and Emamreza hospital, Mashhad University of Medical Sciences were evaluated. Patients were assessed using standardized methods for pure-tone threshold audiometry. The management method of SSNHL treatment included oral steroids combined with IT administration of dexamethasone once a day for 7 days and continuing it on an alternate day and then weekly basis. Patients' recovery was assessed using Siegel's criteria. RESULTS This study included a total of 248 cases of idiopathic sudden hearing loss, with a mean age of 40.63±16.19 years. In total, 105 (42.3%) and 143 (57.7%) patients were female and male, respectively. The most common associated symptoms included tinnitus (86.9%, n=205) followed by vertigo (52.1%, n=122). The final hearing outcome of patients showed that 39 (15.7%), 38(15.3%), 86 (34.7%), and 85 (34.3%) patients underwent a complete recovery, partial recovery, slight recovery, and no recovery, based on Siegel's criteria. CONCLUSIONS The dose, interval, and duration of IT steroid treatment were not universally approved. The treatment method designed based on a tapering of IT steroid injection in combination with already known systemic administration of steroids can be a treatment option in SSNHL patients.

Abstract
OBJECTIVES To describe a cohort of patients presenting with long-term sudden sensorineural hearing loss (SSNHL) treated with prophylactic migraine and intratympanic steroid therapy. METHODS Patients presenting to a neurotology clinic at least 6 weeks from SSNHL onset were included. All patients received migraine prophylactic medication (nortriptyline, topiramate, and/or verapamil) and lifestyle changes for at least 6 weeks, as well as intratympanic steroid injections, if appropriate. RESULTS Twenty-one patients (43% female) with a mean age of 64 ± 11 years who presented 9 ± 8 months (median = 5) from symptom onset were included. Posttreatment hearing thresholds were significantly improved compared with pretreatment thresholds at 500 Hz (49 ± 19 dB versus 55 ± 20 dB, p = 0.01), 1000 Hz (52 ± 19 dB versus 57 ± 21 dB, p = 0.03), low-frequency pure-tone average (53 ± 15 dB versus 57 ± 17 dB, p = 0.01), and speech-frequency pure-tone average (57 ± 13 dB versus 60 ± 15 dB, p = 0.02). Posttreatment word-recognition-score (WRS) and speech-recognition-threshold (SRT) were also significantly improved (45 ± 28% versus 70 ± 28% and 57 ± 18 dB versus 50 ± 16 dB, respectively, both p < 0.01). Notably, ≥15% improvement in WRS and ≥10 dB improvement in SRT was observed in 13 (68%) and 8 (40%) patients, respectively. Of the 11 patients who presented with initial < 50% WRS, 8 (73%) had improved posttreatment >50% WRS with an average improvement of 39 ± 9%. CONCLUSIONS Migraine medications in addition to intratympanic steroid injections significantly improved SRT and hearing frequencies in 40% and 29% of SSNHL patients, respectively, while significant WRS recovery was observed in most (68%) patients. This suggests SSNHL may be an otologic migraine phenomenon, which may be at least partially reversible even after the traditional 30-day postonset window.

Abstract
BACKGROUND Sudden Sensorineural Hearing Loss (SSNHL) is a medical emergency requiring immediate attention as delayed treatment can lead to permanent and devastating consequences. Primary care physicians are likely the first to be presented with SSNHL and therefore have the crucial role of recognizing it and initiating timely and appropriate management. The aim of this study was to gain insight into the current knowledge and practice trends pertaining to the diagnosis and management of SSNHL among family physicians in Canada. METHODS An 18-question survey targeting Canadian family physicians was marketed through two, physician-only discussion groups on the social media platform Facebook. Responses were collected between August 1st and December 22nd 2019 then aggregated and quantified. RESULTS 52 family physicians submitted responses. 94.2% (n = 49) reported that in their practice, unilateral SSNHL warrants urgent referral to otolaryngology and 84.6% (n = 44) reported that unilateral sudden-onset hearing loss warrants urgent referral for audiological testing. 73.1% of participants (n = 38) reported that they would attempt to differentiate between conductive and sensorineural hearing loss if presented with unilateral, acute or sudden-onset hearing loss. 61.5% (n = 32) would rely on tuning fork tests to inform management decisions, as compared to 94.2% (n = 49) relying on case history and 88.5% (n = 46) on otoscopy. 76.9% (n = 40) would prescribe corticosteroids if presented with confirmed, unilateral SSNHL. CONCLUSION The majority of family physicians in the study would make appropriate referral and treatment decisions in the management of SSNHL, understanding it is a medical emergency. Tuning fork tests are under-utilized for informing management decisions compared to other means of differentiating conductive and sensorineural hearing loss. Further research is needed to understand why some family physicians do not prescribe corticosteroids for treatment of SSNHL, which may then identify any gaps in knowledge or inform improvements in clinical protocol.

Abstract
PURPOSE To determine pre- and post-treatment factors that are useful for predicting the prognosis of hearing improvement in idiopathic sudden sensorineural hearing loss (ISSHL). METHODS This retrospective study included 332 patients with ISSHL. Patients received intravenous steroid treatment (prednisolone sodium succinate; 120 mg/day followed by dose tapering). Complete recovery of hearing levels was defined as a final pure-tone audiometry of ≤ 20 dB HL or the same level as the contralateral ear. Patients' age; sex; side of hearing loss; initial hearing level; days from onset to treatment; presence of vertigo, diabetes, and hypertension; and hearing improvement on days 3-4 and 6-7 after treatment initiation were analyzed as potential prognostic factors. RESULTS Overall, 109 patients (32%) had complete recovery. Results of the multivariate logistic regression model identified age (odds ratio [OR] = 0.974), initial hearing level (OR = 0.949), vertigo (OR = 0.409), and hearing improvement on days 6-7 after treatment initiation (OR = 1.11) as significant independent predictors of complete recovery. Age ≥ 60 years, initial hearing level ≥ 72.5 dB HL, and vertigo contributed to poor prognosis. Patients without these three factors and a hearing improvement of ≥ 10 dB HL on days 6-7 post-treatment had a complete recovery rate of 80%. Only 1.5% of the patients with 2-3 of these factors and a hearing improvement of < 10 dB HL on days 6-7 after treatment initiation achieved complete recovery. CONCLUSION Age, initial hearing level, vertigo, and hearing improvement on days 6-7 after treatment initiation were independent predictors of hearing recovery in ISSHL.

Abstract
During the COVID-19 pandemic it is important to recognize every possible symptom of the virus to break the chain of transmission. COVID-19 patients could present with nonspecific symptoms other than those that are commonly known. Sudden sensorineural hearing loss may be one of the symptoms of COVID-19. Until now there have been no reports of COVID-19 patients diagnosed with isolated sudden sensorineural hearing loss.
Objective This study aimed to investigate the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients presenting with only sudden sensorineural hearing loss (SSHNL) during the COVID-19 pandemic. Methods The study included five male patients who presented with the sole complaint of unilateral SSNHL to the otolaryngology outpatient clinic between 03–12 April 2020. The patients were referred to the infectious diseases clinic to be evaluated for SARS-CoV-2 by real time polymerase chain reaction (RT-PCR) testing. Results RT-PCR testing for SARS-CoV-2 was positive in one of the patients and negative in the other four patients. A positive response to COVID-19-specific treatment in the SARS-CoV-2 positive SSNHL patient was noted. Conclusion It should be remembered that non-specific symptoms such as SSNHL could be the only sign with which to recognize a COVID-19 case. Awareness of such a non-specific presentation of COVID-19 patients is crucial during this pandemic period for preventing infectious spread through isolation and early initiation of COVID-19 targeted treatment.

Abstract
Objectives. Prognosticating idiopathic sudden sensorineural hearing loss (ISSNHL) is an important challenge. In our study, a dataset was split into training and test sets and cross-validation was implemented on the training set, thereby determining the hyperparameters for machine learning models with high test accuracy and low bias. The effectiveness of the following five machine learning models for predicting the hearing prognosis in patients with ISSNHL after 1 month of treatment was assessed: adaptive boosting, K-nearest neighbor, multilayer perceptron, random forest (RF), and support vector machine (SVM). Methods. The medical records of 523 patients with ISSNHL admitted to Korea University Ansan Hospital between January 2010 and October 2017 were retrospectively reviewed. In this study, we analyzed data from 227 patients (recovery, 106; no recovery, 121) after excluding those with missing data. To determine risk factors, statistical hypothesis tests (e.g., the two-sample t-test for continuous variables and the chi-square test for categorical variables) were conducted to compare patients who did or did not recover. Variables were selected using an RF model depending on two criteria (mean decreases in the Gini index and accuracy). Results. The SVM model using selected predictors achieved both the highest accuracy (75.36%) and the highest F-score (0.74) on the test set. The RF model with selected variables demonstrated the second-highest accuracy (73.91%) and F-score (0.74). The RF model with the original variables showed the same accuracy (73.91%) as that of the RF model with selected variables, but a lower F-score (0.73). All the tested models, except RF, demonstrated better performance after variable selection based on RF. Conclusion. The SVM model with selected predictors was the best-performing of the tested prediction models. The RF model with selected predictors was the second-best model. Therefore, machine learning models can be used to predict hearing recovery in patients with ISSNHL.

Abstract
OBJECTIVES (a) Determine the demographic and medical risk factors for patients who presented with unilateral idiopathic sudden sensorineural hearing loss (ISSNHL); (b) identify treatments that patients underwent; (c) evaluate the adequacy of follow-up and compliance with long-term hearing rehabilitation. METHODS Retrospective review of patients who presented with unilateral ISSNHL between January 1998 and December 2017 at a tertiary care academic medical center. RESULTS Two hundred-four patients met inclusion criteria. Of these, 129 (63.2%) did not undergo treatment at an outside hospital prior to our evaluation. In this subgroup, the average pretreatment pure tone average (PTA) was 61.9 ± 2.5 dB (dB). The most common treatment was oral steroids and was recommended in 76 patients (59.9%). Patients also underwent intratympanic (IT) steroid injections (7.2%) or oral steroids followed by salvage IT injections (19.4%). Mean follow-up duration was 17.9 (±29.2) months, and posttreatment PTA (45.6 ± 2.6 dB) was significantly better than baseline (P < .001). In this cohort, hearing amplification was infrequently recommended. Less than 20% of patients reported active hearing amplification use at their most recent visit. At follow-up, 90 patients (69.8%) reported subjective improvement in hearing after treatment. Only 55 patients (42.6%) showed improvement in PTA compared to their pretreatment audiograms. CONCLUSION Many patients with ISSNHL experienced audiometric improvement after treatments, but most had persistent hearing loss. The duration of follow-up was short. Most patients did not use long-term hearing amplification. Future studies are needed to identify factors that contribute to reduced follow-up and low compliance with hearing amplification use in ISSNHL. LEVEL OF EVIDENCE 2c.

Abstract
PURPOSE Idiopathic sudden sensorineural hearing loss (ISSHL) is a hearing impairment greater than 30 dB at three consecutive frequencies developing in less than 3 days. The aim of this study was to evaluate VEMPs and caloric testing in patients affected by ISSHL without vertigo. METHODS We retrospectively evaluated 35 subjects affected by ISSHL. The audio-vestibular investigation consisted of pure-tone and speech audiometry, impedance, bithermal caloric testing, oVEMPs and cVEMPs. RESULTS VEMPS were abnormal in 21 patients (60%): cVEMPs in 12 (34.2%) and oVEMPs in 19 (54.2%). 10 patients (28.5%) presented with both c-and oVEMPs altered. Subjects without vestibular involvement showed a significant lower PTA in the affected ear both at admission and at discharge. Recovery rate was significantly higher in group without vestibular involvement. CONCLUSION The evaluation of the vestibular system can be useful for predicting the auditory recovery in patients without vertigo also.

Abstract
Importance Sudden sensorineural hearing loss (SSHL) accompanied by vertigo may portend a negative prognosis in the hearing outcome. Objective To investigate the association of vertigo with prognosis of hearing variables in SSHL. Data Sources A literature search of eligible studies was performed in PubMed, Web of Science, and Embase from September 26, 1973, through September 26, 2017. Studies published in English were retrieved with no restrictions on the date of publication. References were identified by screening the proceedings of relevant reviews, and annual meeting and other correlative papers were scanned manually for enrollment. Study Selection All original research studies and retrospective or prospective studies focusing on the role of vertigo in the prognosis for the hearing outcome of SSHL were systematically retrieved. Studies that did not include data regarding the association between the rate of hearing recovery and vertigo were excluded, as were reviews, comments, case reports, editorials, letters, and practice guidelines. Data Extraction and Synthesis Data were extracted and evaluated by 2 researchers. Data extracted included research type, number of participants with or without vertigo, treatment regime, definition of pure-tone average, criteria for hearing improvement, and length of follow-up. The quality of included studies was evaluated using the Newcastle-Ottawa Scale (scores range from 0-9, with a score of ≥6 indicating a high-quality study). The data were synthesized in Mantel-Haenszel models; the aggregate results were estimated in forest plots. Main Outcomes and Measures Association of vertigo with the prognosis for the hearing outcome of SSHL. Results Of the 4814 unique patients identified in 10 studies, 1709 were included in the SSHL group with vertigo and 3105 were included in SSHL group without vertigo. The Newcastle-Ottawa Scale score of each study selected was greater than 7. The recovery rate of hearing was 42.13% in the group with vertigo, compared with 60.29% in the group without vertigo. Vertigo was significantly associated with a worse hearing recovery (odds ratio, 2.22; 95% CI, 1.54-3.20; I2 = 74%). Similar results were obtained in subgroup analyses of the grading system using the Siegel criteria and systemic corticosteroid therapy. However, no association of vertigo with the prognosis of SSHL was observed within the subgroup receiving intratympanic corticosteroids (odds ratio, 1.78; 95% CI, 0.64-4.94; I2 = 70%). Conclusions and Relevance Current evidence revealed that vertigo may be negatively associated with hearing recovery in patients with SSHL, except in a subgroup that received intratympanic corticosteroids. Corticosteroid injection may be more effective for treatment of SSHL accompanied by vertigo; future studies are needed to determine whether treatment of vertigo might contribute to the recovery of SSHL.

Abstract
BACKGROUND Efficacy of current treatment methods in idiopathic sudden sensorineural hearing loss (ISSNHL) is still unsatisfactory. OBJECTIVE This study aimed to discover in differences in effect between steroid applications responsible for promoting the prognosis in ISSNHL. MATERIALS AND METHODS A study was conducted to diagnose ISSNHL patients in our hospital from January 2014 to September 2016. All patients accepted treatments including intravenous injection (intravenous dexamethasone, [IV DXM]), intratympanic injection (intratympanic methylprednisolone [IT MP], intratympanic dexamethasone [IT DXM]) or combined injections with steroids (IV + IT DXM). Patients were divided into groups according to treatment outcomes and clinical characteristics of each group were compared for univariate comparison. Logistic regression was utilized to verify screening factors from univariate comparison for exclude biases. RESULTS There were 313 patients with ISSNHL enrolled in the study. Logistic regression verified that vertigo (p = .023), severity of hearing loss (p=.969), pattern of hearing loss (p = .03), and the treatment method (p < .001) were statistically related to the patients' prognosis based on the condition all biases had been excluded as possible. IT MP showed a better prognosis of hearing improvement compared to treatment with IT DXM (OR = 0.5), IV DXM (OR =0.226), and IV DXM + IV DXM (OR = 0.320). CONCLUSIONS AND SIGNIFICANCE IT MP treatment could be utilized as initial treatment in ISSNHL and might promote outcomes.

Abstract
PURPOSE Tympanotomy and sealing of labyrinthine membranes has become in some centers used to treat severe to profound sudden sensorineural hearing loss refractory to conservative treatment. The aim of this retrospective study was to determine which preoperative factors influence the likelihood of postoperative recovery according to different audiological assessment criteria. METHODS The mean final hearing threshold, the hearing improvement, the probability of a complete recovery according to two different classifications, and probability of a significant recovery of 136 adult subjects were studied by univariate and multivariate analyses. RESULTS The subject's mean postoperative 4-pure-tone-average was 63.9 ± 35.9 dB, the mean improvement was 42.8 ± 32.6 dB. Depending on the classification system used, 18.4-28.0% of subjects experienced a complete recovery. 77.2% of subjects had a significant hearing improvement. History of a pressure change (odds ratio (OR):4.6) was the only positive prognostic factor for hearing improvement. It also enhanced probability of experiencing a complete hearing recovery (OR: 2.8-6.3). Preoperative total deafness (OR: 1.5-1.9) and vertigo (OR: 3.3-4.6) were negative prognostic factors for the mean final hearing threshold and the probability of a complete hearing recovery. Patients with a preceding pressure change event achieved a complete recovery in 45.5-50.0%, those without such an event recovered completely only in 13.2-23.7%. CONCLUSION Evaluating prognostic factors and the rate of complete hearing recovery are influenced by the underlying assessment parameters. In addition to the mean postoperative hearing threshold and hearing gain, the probability of regaining a serviceable hearing is clinically important for the individual and should be added to the assessment criteria in future studies.

Abstract
Background Sudden sensorineural hearing loss (SSHL) not only involves cochlear function but might also be accompanied by vestibular disturbances. The assessment of vestibular function could be of great relevance in SSHL. Objective To investigate the prevalence of vestibulocochlear lesions in SSHL and the correlation of specific vestibular organs with hearing prognosis. Data sources A complete literature search of eligible studies in the PubMed and EMBASE databases was performed. Study selection For our aim, studies that focused on vestibular examination in the case of SSHL were retrieved, including caloric tests, cervical vestibular-evoked myogenic potential (cVEMP) tests, or ocular vestibular-evoked myogenic potential (oVEMP) tests. Results Of the 18 studies included, a caloric test was performed in 16 studies, cVEMP in 13 studies, and oVEMP in 5 studies, and together the studies included a total population of 1,468 subjects. The scores on the Agency for Healthcare Research and Quality (AHRQ) questionnaire ranged from 6 to 11. These results indicated that the most commonly damaged vestibular organ in SSHL was the utricle and superior vestibular pathway (U + S) followed by the lateral semicircular canal and superior vestibular pathway (LSC + S), the saccule and inferior vestibular pathway (S + I), and the cochlea only (C only). The meta-analysis indicated that SSHL patients with vertigo have a statistically increased risk of vestibular organ lesions compared with those without vertigo, including the LSC + S subgroup (OR = 4.89, 95% CI = 1.20-19.93, I2 = 80%, p = 0.03) and the S + I subgroup (OR = 3.58, 95% CI = 1.61-7.95, I2 = 0%, p = 0.002). The pooled possibility of hearing recovery within the LSC + S lesion group was less than half that of the non-LSC + S lesion group (OR = 0.24, 95% CI = 0.11-0.52, I2 = 68%, p = 0.0003). Conclusion This study shows the relevance of vestibular damage concomitant with SSHL and that SSHL patients with vertigo are at an increased risk of vestibular organ lesions compared with patients without vertigo. LSC + S lesions thus appear to be a critical variable that influence the possibility of hearing improvement in SSHL.

Abstract
AbstractObjective:Recent studies found that mobile phone users had a significantly greater risk of having elevated thresholds in speech frequencies. This study investigated the correlation between the laterality of sudden sensorineural hearing loss, handedness and the preferred ear for mobile phone use.Methods:The study included all patients who presented with sudden sensorineural hearing loss to the Department of Otolaryngology – Head and Neck Surgery in our tertiary referral medical centre between 2014 and 2016. Patients were asked to indicate their dominant hand and preferred ear for mobile phone use.Results:The study comprised 160 patients. No correlation was found between the dominant hand or preferred ear for mobile phone use and the side of sudden sensorineural hearing loss. There was no correlation between the side of the sudden sensorineural hearing loss (preferable or non-preferable for mobile phone use) and audiometric characteristics.Conclusion:No correlation was found between the laterality of ears used for mobile phone and sudden sensorineural hearing loss.
