    Full Text Available Abstract Background Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. Case presentations We encountered a patient with sensorineural hearing loss complicating scrub typhus, and three patients with scrub typhus who complained of otalgia, which was sudden onset, severe, paroxysmal, intermittent yet persistent pain lasting for several seconds, appeared within 1 week after the onset of fever and rash. The acute sensorineural hearing loss and otalgia were resolved after antibiotic administration. Conclusion When patients in endemic areas present with fever and rash and have sensorineural hearing loss or otalgia without otoscopic abnormalities, clinicians should suspect scrub typhus and consider empirical antibiotic therapy.

    Sudden onset sensorineural hearing loss is a medical emergency that continues to be poorly understood despite being recognized in the literature since 1944 (De Kleyn, 1944). A commonly used criterion to qualify for this diagnosis is a sensorineural hearing loss over three contiguous pure-tone frequencies of 30 dB or more that develops within 72 hours. The vast majority of cases are unilateral and the estimated annual incidence is 20 per 100 000 persons (Nosrati-Zarenoe et al, 2007). A cause for the hearing loss is only identified in up to 10% of cases but 50% of patients will improve spontaneously (Penido et al, 2009).

    Abstract Sudden sensorineural hearing loss (SSHL) is an otological emergency defined as a rapid hearing loss, seriously affects patient's social life. To data, no study has reported the treatment by acupuncture alone in the acute phase. In this report, Acupuncture and Moxibustion therapy of excitation-focus transfer is outlined. The patient was a 26-year-old young woman who had an SSHL coupled with ear fullness. The patient had no past medical history, but she had undergone variable emotions and had a history of excessive noise exposure. The patient refused to receive any medicine especially steroids and hyperbaric oxygen therapy. She just only received acupuncture treatment. Her symptoms and outcome measurements were improved every week and completely recovered after the last week. Even though the article presents a single case and is based on self-reports, there are very clear trends on how patients with SSHL responded to acupuncture treatments. PMID:27368045

    Peginterferon and ribavirin combination therapy for the treatment of hepatitis C virus (HCV) is well known to be associated with significant adverse effects. Sensorineural hearing loss, that in most cases is unilateral, has been reported as a consequence of therapy with both non-pegylated and pegylated interferon (pegIFN) but is not a well-known adverse effect. We report a 45-year-old Caucasian woman who developed acute sensorineural hearing loss 2 mo after starting therapy with pegIFN-α 2b and ribavirin for the treatment of chronic HCV, genotype 1a. She did not report the hearing loss to the hepatitis clinic until L mo,later whereupon therapy was promptly discontinued.Although her serum alanine aminotransferase (ALT)normalized and her HCV-RNA became undetectable after 12 wk of pegIFN and ribavirin therapy, after discontinuation,her HCV-RNA became detectable with significant elevations of serum ALT. Four months after initial discontinuation,the patient re-commenced pegIFN and ribavirin combination therapy. After 44 of 48 wk of therapy, the patient's liver biochemistry has normalized and the HCV-RNA is undetectable. She has not developed worsening of her hearing loss and hearing on the left-side is unaffected.Both patients and physicians should be aware that sensorineural hearing loss may occur with pegIFN therapy.Our experience suggests that re-institution of therapy is not always associated with further hearing impairment.

    Sudden sensorineural hearing loss is defined as sudden unilateral or bilateral sensorineural hearing loss with at least 30 dB decrease in threshold in 3 contiguous test frequencies occurring over 72 hours or less. It is rare among children. The mechanism of the process and prognosis of the disorder remains unclear. The current incidence of sudden sensorineural hearing loss among pediatric population is unknown. The authors carried out a retrospective chart analysis of patients under 15 years of age from 2004 to 2015, who consulted to the Otolaryngology Head and Neck Surgery Department of Inonu University Medical Faculty. Age, sex, number of affected ear and side, audiometric evaluations, medical follow-up, treatment method, duration of treatment recovery, associated complaints; tinnitus and/or vertigo, presence of mumps disease were recorded for each patient. A 4-frequency pure-tone average (500, 1000, 2000, and 4000 Hz) was calculated for each ear. Complete recovery, defined as some hearing level compared with the nonaffected ear, was observed in 3 patients (21.4 %) and there was no partial hearing recovery. The hearing loss of 11 patient remained unchanged after prednisolone treatment. Two of the 11 patients had bilaterally total sensorineural hearing loss and evaluated as appropriate for cochlear implantation. Sex of patient and laterality of hearing loss were not correlated with hearing recovery. Sensorineural hearing loss among pediatrics has been the issue of otolaryngologists. The incidence, etiology, and treatment methods should be more studied.

    Full Text Available Abstract Introduction Lassa fever is an acute arena viral haemorrhagic fever with varied neurological sequelae. Sensorineural hearing loss is one of the rare complications which occur usually during the convalescent stage of the infection. Case presentation The cases of two female patients aged 19 and 43 years old, respectively, with clinical features suggestive of Lassa fever and confirmed by immunoserological/Lassa-virus-specific reverse transcriptase polymerase chain reaction are presented. Both patients developed severe sensorineural hearing loss at acute phases of the infections. Conclusion Sensorineural hearing loss from Lassa fever infections can occur in both acute and convalescent stages and is probably induced by an immune response.

    The objective of the study was to examine the aetiology of sensorineural hearing loss (SNHL) in a paediatric population presenting to the National Centre of Medical Genetics. A retrospective chart review from 1998 to 2006. One hundred and twenty nine children were investigated for SNHL. The average age of diagnosis of hearing loss was 36 months. The degree of hearing loss was mild in 8 children, moderate in 33 children, severe in 31 children and profound in 57 children. Eighty-five children (66%) were diagnosed with a hereditary hearing loss, 11 (8%) children had an acquired hearing loss and no cause found in 33 (26%) children. This is the first report of the causes of hearing loss in Irish children. The mean age of diagnosis in our cohort is high and emphasises the need for a neonatal screening programme. There remains a number of children for whom the cause of hearing loss remains unknown.

    Full Text Available Background. Sudden sensorineural hearing loss (SSHL caused by opiate abuse or overuse has been well documented in the medical literature. Most documented case reports have involved either heroin or hydrocodone/acetaminophen. Recently, case reposts of methadone induced SSHL have been published. Case Report. We present the case of a 31-year-old man who developed SSHL after a methadone overdose induced stupor. He was subsequently restarted on methadone at his regular dose. On follow-up audiometry exams, he displayed persistent moderately severe sensorineural hearing loss bilaterally. Discussion. This case is notable because unlike all but one previously reported case, the patient—who was restated on methadone—did not make a complete recovery. Conclusion. Methadone overuse in rare cases causes SSHL.

    Sensorineural hearing loss is a complex disease state influenced by genetics, age, noise, and many other factors. This article reviews our current knowledge regarding the causes of sensorineural hearing loss and reviews the more challenging clinical presentations of sensorineural hearing loss. We have reviewed the latest medical literature in an attempt to provide an evidence-based strategy for the assessment and management of sudden sensorineural hearing loss, rapidly progressive sensorineural hearing loss, and asymmetric/unilateral sensorineural hearing loss.

    Sudden sensorineural hearing loss (SSNHL) is generally defined as sensorineural hearing loss of 30 dB or greater over at least three contiguous audiometric frequencies and within a three-day period. This hearing loss is usually unilateral and can be associated with tinnitus and vertigo. The pathogenesis of unilateral sudden sensorineural hearing loss is still unknown, and the alterations in the functional connectivity are suspected to involve one possible pathogenesis. Despite scarce findings with respect to alterations in brain functional networks in unilateral sudden sensorineural hearing loss, the alterations of the whole brain functional connectome and whether these alterations were already in existence in the acute period remains unknown. The aim of this study was to investigate the alterations of brain functional connectome in two large samples of unilateral sudden sensorineural hearing loss patients and to investigate the correlation between unilateral sudden sensorineural hearing loss characteristics and changes in the functional network properties. Pure tone audiometry was performed to assess hearing ability. Abnormal changes in the peripheral auditory system were examined using conventional magnetic resonance imaging. The graph theoretical network analysis method was used to detect brain connectome alterations in unilateral sudden sensorineural hearing loss. Compared with the control groups, both groups of unilateral SSNHL patients exhibited a significantly increased clustering coefficient, global efficiency, and local efficiency but a significantly decreased characteristic path length. In addition, the primary increased nodal strength (e.g., nodal betweenness, hubs) was observed in several regions primarily, including the limbic and paralimbic systems, and in the auditory network brain areas. These findings suggest that the alteration of network organization already exists in unilateral sudden sensorineural hearing loss patients within the acute period

    Sudden sensorineural hearing loss is a symptom of cochlear injury. Potential aetiologies are vascular diseases, viral infections, allergic reactions, autoimmune disorders, and traumatic rupture of the intralabyrinthe membrane. Unlike in unilateral cases bilateral sensorineural hearing loss is often associated with specific disease entities. We report a case of sudden bilateral deafness after intravenous heroin abuse. The putative pathophysiological mechanisms are discussed.

  17. Hearing Disorders and Sensorineural Aging

    Directory of Open Access Journals (Sweden)

    Alessandra Fioretti

    2014-01-01

    Full Text Available The physiological age-related hearing loss is defined as presbycusis and it is characterized by reduced hearing sensitivity and problems in understanding spoken language especially in a noisy environment. In elderly the reduced speech recognition is generally caused by a reduction of the cochlear cells in the organ of Corti and degeneration of the central auditory pathways. In order to have a complete management strategy of central and peripheral presbycusis the diagnostic evaluation should include clinical ENT examination, standard audiological tests, and tests of central auditory function. Treatment should include not only the appropriate instruments for peripheral compensation but also auditory rehabilitative training and counseling to prevent social isolation and loss of autonomy. Other common hearing disorders in elderly are tinnitus and hyperacusis which are often undervalued. Tinnitus is characterized by the perception of a “phantom” sound due to abnormal auditory perception. Hyperacusis is defined as a reduced tolerance to ordinary environmental sounds. Furthermore auditory, visual, nociceptive, and proprioceptive systems may be involved together in a possible context of “sensorineural aging.” The aim of this review is to underline the presence of hearing disorders like tinnitus and hyperacusis which in many cases coexist with hearing loss in elderly.

  18. Sensorineural Hearing Loss Associated with Kawasaki Disease

    2014-04-01

    Full Text Available Kawasaki disease (KD is an acute systemic vasculitis of children characterized by fever, rash, conjunctival hyperemia, oropharyngeal erythema, edema and erythema of the hands and feet, and cervical adenopathy [1]. A variety of other features are also characteristics of this syndrome, including coronary artery aneurysms, urethritis, anterior uveitis, mild hepatobiliary dysfunction, and gallbladder hydrops. Coronary artery abnormalities, including aneurysms and ectasia, occur in approximately 20% of untreated patients [2]. Neurologic involvement is rare. Cranial nerve palsy, especially involving the seventh nerve, has been reported [3], as well as hemiparesis caused by cerebral thrombosis and infarction, and convulsions. Although about 30% of patients with acute KD in the United States have been reported to suffer mild sensorineural hearing loss (SNHL [4], only a few such cases have been reported in Japan. On the other hand, in both countries, a few cases of severe or profound SNHL in children who were in the acute phase of KD have been documented [5].

    In this article, the sensorineural hearing loss is presented as a possible sequelae of neonatal hyperbilirubinemia. In our program of early hipoacusia detection, 241 babies were examined from January 1996 until November 1999; 7 cases had a history of hyperbilirubinemia in the neonatal period and 2 of them were diagnosed of sensorineural hearing loss. We discuss how the bilirubin or any other associated factor might have been the cause and this could explain the selective affectation of some children.

    2008-02-01

    The aim of this study is to demonstrate the association of Chikungunya virus and sudden sensorineural hearing loss. In the case report described we had a case which developed sudden unilateral sensorineural hearing loss following chikungunya fever. A 15-year-old female presented to us with the complains of unilateral sudden onset of hearing loss following an episode of fever, arthralgia and rashes 1 month ago. At the time of these symptoms there were many cases of chikungunya fever in the city, three being in her locality. Clinically Chikungunya fever was suspected and a positive serological test further confirmed our diagnosis. The hearing loss could thus be attributed to Chikungunya virus. Viruses have always been implicated in causing sudden sensorineural hearing loss but Chikungunya virus as a cause has not been documented earlier making this case report a unique one.

    Unilateral, acute onset sensorineural hearing loss (“sudden sensorineural hearing loss” [SSNHL]) as an isolated event without other associated neurological deficits usually results from a lesion of the cochlea. Lesions in the ascending central auditory pathways cranial to the cochlear nucleus seldom result in unilateral hearing loss due to decussation of the central auditory pathways at multiple levels. We describe a patient with a tiny acute infarct in the right pons resulting in isolated ac...

    We present a rare case of medulloblastoma which presented with unilateral sudden sensorineural hearing loss as an initial symptom. A 19-year-old man was admitted to our hospital with a chief complaint of dizziness and facial numbness on the right side. His illness had begun two years previously with sudden hearing loss on the right side, for which he had been treated as an idiopathic sudden hearing loss. Magnetic resonance imaging demonstrated abnormal signals located mainly in the right middle cerebellar peduncle. We performed partial resection of the tumor by suboccipital craniotomy. The histopathological diagnosis was medulloblastoma. Intrinsic brain tumor is an extremely rare cause of sudden sensorineural hearing loss and is therefore easily overlooked as was in the present case. The present case highlights not only the need to evaluate patients with sudden sensorineural hearing loss by magnetic resonance imaging but also the importance of paying attention to intrinsic lesions involving the brainstem. Although this condition like the presented case might be rare, intrinsic brain tumor should be considered as a potential cause of sudden sensorineural hearing loss, as it may be easily missed leading to a delay in appropriate treatment.

    The enhanced MRI hearing findings of the inner ear in 124 patients with sensorineural hearing loss were evaluated. MR images were obtained before and after the intravenous administration of gadolinium (0.1 mmol/kg). In three out of seventy-nine patients with unilateral healing loss, cochlear and/or the vestibular enhancement was noted on the symptomatic side. The positive cases included those with Ramsay-Hunt syndrome, mumps and so-called sudden deafness. Forty-five patients with bilateral hearing loss showed no enhancement within the inner ear. Although positive gadolinium enhancement of the inner ear may detect inflammatory lesions due to a viral infection, its incidence in sensorineural hearing loss, including cases of sudden deafness. seems to be extremely rare.

    The Vibrant Soundbridge is a means to rehabilitate patients with sensorineural hearing loss. It differs from hearing aids in that it uses mechanical energy rather than acoustic sound to deliver better sound quality to the inner ear. The implant's crucial component is a floating mass transducer that is directly fixed to the incus to drive it, which is introduced into the middle ear through a facial recess approach. Although this is a newer technology, studies thus far have demonstrated better hearing results compared with hearing aids in terms of functional gain and speech intelligibility, and better outcomes on subjective assessments.

    The phosphodiesterase type 5 (PDE-5) inhibitors-sildenafil, vardenafil, and tadalafil-are used primarily in erectile dysfunction, but sildenafil is also indicated for pulmonary hypertension. Common adverse effects of vardenafil include headache, flushing, nasal congestion, dyspepsia, and nausea. Recently, PDE-5 inhibitors have been associated with adverse vision effects, and emerging evidence now indicates that they may also be responsible for hearing changes and hearing loss. We describe a patient who developed unilateral sudden sensorineural hearing loss possibly related to the use of vardenafil for erectile dysfunction. To our knowledge, only one other case of hearing loss related to this drug class has been published. Our patient was a 57-year-old man who came to the emergency department with right-sided mild-to-moderate hearing loss in the 500-3000-Hz range, confirmed by audiogram, that occurred after ingestion of vardenafil. The patient was hospitalized 2 days later for administration of intravenous dexamethasone, followed by oral prednisone. He reported that his hearing had improved on the fourth hospital day and was discharged 3 days later, continuing to taper the prednisone on an outpatient basis. A repeat audiogram after 10 days of corticosteroid therapy confirmed that his hearing in the 500-3000-Hz range was within normal limits. Use of the Naranjo adverse drug reaction probability scale indicated a possible (score of 3) adverse reaction of sudden sensorineural hearing loss associated with vardenafil consumption. We also performed an analysis of hearing loss cases related to PDE-5 inhibitors in the United States Food and Drug Administration's Adverse Event Reporting System database to compare the characteristics of our patient with those of other reported adverse event cases. Based on the temporal relation of the sudden sensorineural hearing loss to this patient's drug consumption, we propose that the vardenafil is a likely cause of the hearing loss

  14. Sensorineural hearing loss in hemorrhagic dengue?

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Discussion and conclusion: This is the first case report that brings together DHF and sudden hearing loss. In the development of this case no other cause to sudden hearing loss was found and the correlation between dengue and hearing loss was questioned. In the literature review was found that some viruses, as mumps virus, varicella-zoster virus and HSV-1 and HSV-2 are related to sudden hearing loss, all of them fit in the viral theory. Besides the viral theory of sudden hearing loss, there is the vascular theory that is the occlusion of the end artery that supplies the cochlea. DHF has a vascular commitment, and the hypothesis of a vascular cause could be elicited in this case. Many studies in this area are needed and this article has the objective of elicit the discussion about the subject. Could dengue be associated with sensorineural hearing loss?

    Unilateral, acute onset sensorineural hearing loss ("sudden sensorineural hearing loss" [SSNHL]) as an isolated event without other associated neurological deficits usually results from a lesion of the cochlea. Lesions in the ascending central auditory pathways cranial to the cochlear nucleus seldom result in unilateral hearing loss due to decussation of the central auditory pathways at multiple levels. We describe a patient with a tiny acute infarct in the right pons resulting in isolated acute onset left-sided SSHNL, without any other associated acute neurological deficits.

    The primary care physician's role in recognizing sudden sensorineural hearing (SSNHL) loss and delivering initial treatment is critical in the management of the syndrome. This role involves recognizing its clinical symptoms, distinguishing it from conductive hearing loss with the Weber tuning fork or the Rauch hum test, and urgent administration of high dose oral corticosteroids. Diagnosis and treatment should not be delayed for audiometric testing or referral to otolaryngology. This paper provides an update on the initial evaluation and treatment of this syndrome based on the literature and clinical guideline recommendations.

    In this article, the mechanism of inheritance behind inherited hearing loss and genetic susceptibility in noise-induced hearing loss are reviewed. Conventional treatments for sensorineural hearing loss (SNHL), i.e. hearing aid and cochlear implant, are effective for some cases, but not without limitations. For example, they provide little benefit for patients of profound SNHL or neural hearing loss, especially when the hearing loss is in poor dynamic range and with low frequency resolution. We emphasize the most recent evidence-based treatment in this field, which includes gene therapy and allotransplantation of stem cells. Their promising results have shown that they might be options of treatment for profound SNHL and neural hearing loss. Although some treatments are still at the experimental stage, it is helpful to be aware of the novel therapies and endeavour to explore the feasibility of their clinical application.

    Full Text Available A few cases of mild to moderate, gradual and reversible sensorineural hearing loss (SNHL with prolonged doses of nonsteroidal anti-inflammatory drugs has been reported. We present a case of sudden irreversible SNHL in a 60-year-old female after taking a single dose of diclofenac. The patient was a known case of diabetes mellitus and hypertension and was on regular treatment. We postulate that the patient's hearing loss was the result of diclofenac's ototoxic effects which may have been potentiated as a result of her long standing diabetes, hypertension and old age. Accordingly, we recommend the cautious use of diclofenac in patients with underlying diseases where diclofenac induced ototoxicity could potentially result in adverse otologic consequences.

    Full Text Available Kawasaki disease is a common nonspecific vasculitis seen in childhood. The most significant long-term sequela is coronary artery aneurysm. However, the spectrum of complications involves not only the heart, but also other organs such as the eyes, skin, kidneys, gallbladder, liver, and central nervous system. Sensorineural hearing loss (SNHL is a relatively unrecognized complication of the disease. Although most of the complications (except coronary artery aneurysm are self-limiting, SNHL can be persistent. It is, especially important in infants and young children who might not be able to report the hearing deficits and are most likely to have cognitive and speech delays if this hearing loss is not addressed in a timely manner. We report a child with Kawasaki disease who had SNHL during the 2 nd week of the illness. The aim of this article is to briefly review the pathophysiology behind this hearing loss and strongly emphasize the importance of universal hearing evaluation in all children diagnosed with Kawasaki disease. This screening in children with Kawasaki disease may provide some timely intervention if needed. Since most Kawasaki disease patients will be seen by cardiologists, we hope to create more awareness about this complication to the cardiology community as well.

    Full Text Available Introduction: Sudden sensorineural hearing loss (SSNHL has a prevalence of 10 in 100,000. Viral infections, vascular obstruction and rupture of the intracochlear membranes are supposed to be its most common etiologies. About 40% of patients experience vertigo or imbalance. The VEMP (vestibular evoked myogenic potentials test is a known approach for detailed study of the labyrinth. The advantage of this test in comparison to other tests is the selected study of sacculus and sacculocochlear pathways. Materials and Methods:  In this cross sectional study all patients with SSNHL diagnosis were admitted and underwent routine standard treatments and diagnostic tests. Clinical symptoms and paraclinic findings were recorded in especially designed forms and VEMP test was performed on admission. Results: Among the 43 cases with sudden sensorineural hearing loss, 14 (32.6% had vertigo. Thirteen patients (39.2% out of 43 had a negative (abnormal VEMP, 6 of which (42.9% had vertigo, while in the 30 VEMP positive (normal cases, vertigo was detected in 8 (26.6%. Discussion: Saccular dysfunction seems to be an important finding in SSNHL. Although it is more prevalent in the patients with vertigo, it can be found in the non-dizzy cases. VEMP disturbance in SSNHL shows more extensive pathological involvement. Conclusion: In SSNHL the pathology isn’t limited to the cochlea and even in patients with no vestibular symptoms sacculus might be involved.

    Sudden sensorineural hearing loss is characterized by acute, idiopathic hearing deterioration. We report here the development and evaluation of "constraint-induced sound therapy", which is based on a well-established neuro-rehabilitation approach, and which is characterized by the plugging of the intact ear ("constraint") and the simultaneous, extensive stimulation of the affected ear with music. The sudden sensorineural hearing loss patients who received the constraint-induced sound therapy in addition to the standard corticosteroid therapy showed significantly better recovery of hearing function compared to those who had only received corticosteroid treatments. Additionally, the brain activity obtained in a subgroup of patients suggested that the constraint-induced sound therapy could have prevented maladaptive auditory cortex reorganization. Constraint-induced sound therapy thus appears to be an effective, practical, and safe treatment option for sudden sensorineural hearing loss.

    Full Text Available Introduction: Glaucoma is one of the leading causes of blindness throughout the world. Some studies have suggested a relationship between glaucoma and sensorineural hearing loss, while others have found no evidence of an association. We performed a study to determine whether there is a significant difference in hearing of patients with glaucoma and a match control population. Methods: In this cross-sectional study, from February, 2005 till April, 2006, 44 patients with glaucoma were studied. The age range was between 15 to 60 years. After taking a complete medical history, those suffering from presbycusis, history of exposure to ototoxic drugs and substances and history of ear surgery were excluded from the study. All of the patients were cases of open-angle glaucoma, and were surveyed separately for normal-pressure glaucoma. Then complete audiometric tests (PTA, SDS, SRT, Impedance were conducted for all of them, and the results compared with a control group. Results: There was no statistically significant difference between the case group and control group in PTA, SDS, and SRT, except for Normal Tension Glaucoma (NTG. There wasn't any statistically significant difference between two groups with respect to age, gender, and history of diseases. In the NTG group, significant difference was seen only in high frequencies. Conclusion: As mentioned, there was a statistically significant difference between NTG group and control group. It is therefore recommended to conduct complete audiometric tests and histopathologic examinations in this group for early detection of hearing loss and application of rehabilitative measures.

    Sudden sensorineural hearing loss (SSHL) is characterized by acute, idiopathic hearing loss. The estimated incidence rate is 5-30 cases per 100,000 people per year. The causes of SSHL and the mechanisms underlying SSHL currently remain unknown. Based on several hypotheses such as a circulatory disturbance to the cochlea, viral infection, and autoimmune disease, pharmaco-therapeutic approaches have been applied to treat SSHL patients; however, the efficacy of the standard treatment, corticosteroid therapy, is still under debate. Exposure to intense sounds has been shown to cause permanent damage to the auditory system; however, exposure to a moderate level enriched acoustic environment after noise trauma may reduce hearing impairments. Several neuroimaging studies recently suggested that the onset of SSHL induced maladaptive cortical reorganization in the human auditory cortex, and that the degree of cortical reorganization in the acute SSHL phase negatively correlated with the recovery rate from hearing loss. This article reports the development of a novel neuro-rehabilitation approach for SSHL, "constraint-induced sound therapy (CIST)". The aim of the CIST protocol is to prevent or reduce maladaptive cortical reorganization by using an enriched acoustic environment. The canal of the intact ear of SSHL patients is plugged in order to motivate them to actively use the affected ear and thereby prevent progress of maladaptive cortical reorganization. The affected ear is also exposed to music via a headphone for 6 hr per day during hospitalization. The CIST protocol appears to be a safe, easy, inexpensive, and effective treatment for SSHL.

Aims and Objectives: (1 To know the incidence of pure USNHL (other ear being normal in patients complaining of HL. (2 To establish the type and degree of USNHL in patients. Materials and Methods: This study was conducted over a period of more than 1 year to find out the pattern of pure USNHL (other ear being normal in the patients attending ear, nose, and throat outpatient department (OPD with a complaint of HL. Pure tone audiometry data of 1800 cases between August 2014 and December 2015 with HL were analyzed for this study. Demographic characteristics were compared with types and degrees of unilateral sensorineural hearing impairment. Results: A total of 1800 OPD patients who had a complaint of HL and had undergone pure tone audigram (PTA in a period of more than 1 year in the Department of Otorhinolaryngology and Head and Neck Surgery were studied. SNHL type was the highest with 802 cases (44.55%. Out of 802 cases of SNHL, 257 (32.05% were USNHL - out of which, only 155 patients (60.31% had pure USNHL with other ear being normal; this constituted the study group, i.e., 155 patients (8.6% out of 1800. Age of patients ranged from 9 years to 76 years (mean age - 41.5 years. Male:female ratio was 1.31:1. Both ears were almost equally involved. The highest numbers of USNHL patients were seen in the age group of 31-40 years (23.87%. Most cases presented with mild (34.2%, followed by profound (31.6% USNHL. Conclusion: Our study concluded that SNHL type is the most common type (44.55% of hearing impairment among patients complaining of HL. The incidence of pure USNHL (i.e. other ear being normal was 60.31% (155/257 cases of USNHL, 19.32% (155/802 cases of SNHL, and 8.6% (155/1800 cases of PTA performed on patients complaining of HL.

    A retrospective chart review was used for 31 patients with sudden, progressive or fluctuating sensorineural hearing loss (SHL) in the only hearing ear who had been consecutively evaluated at the ENT, Audiology and Phoniatrics Unit of the University of Pisa. The group of patients was evaluated with a complete history review, clinical evaluation, imaging exam (MRI, CT), audiologic tests (tone and speech audiometry, tympanometry, study of stapedial reflexes, ABR and otoacoustic emission) evaluation. In order to exclude genetic causes, patients were screened for CX 26 and CX30 mutations and for mitochondrial DNA mutation A1555G. Patients with sudden or rapidly progressive SHL in the only hearing ear were treated with osmotic diuretics and corticosteroids. In patients who did not respond to intravenous therapy we performed intratympanic injections of corticosteroid. Hearing aids were fitted when indicated and patients who developed severe to profound SHL were scheduled for cochlear implant surgery. The aim of this study is to report and discuss the epidemiology, aetiopathogenesis, therapy and clinical characteristic of patients affected by SHL in the only hearing hear and to discuss the issues related to the cochlear implant procedure in some of these patients, with regard to indications, choice of the ear to implant and results.

    Profound idiopathic sudden sensorineural hearing loss is thought to have a poor prognosis, but few studies have focused on this condition. We aimed to assess the impact of patient factors, audiologic parameters, and salvage intratympanic steroid injection therapy on the prognosis of profound idiopathic sudden sensorineural hearing loss. The demographic, clinical, and audiologic data, degree of hearing recovery, and efficacy of intratympanic steroid injection therapy in 576 patients with profound idiopathic sudden sensorineural hearing loss (mean age 56.2 ± 14.9 years) who had been admitted at four tertiary referral centers between 2000 and 2011 were retrospectively reviewed. The mean hearing level at the initial presentation was 108.1 ± 9.5 dB. Many patients experienced vertigo (52.1%) and tinnitus (77.4%). At the 2-month follow-up, 172 (29.8%) patients showed some degree of hearing recovery, but only 21 (3.6%) patients recovered normal hearing. Further, the 116 patients who had received salvage intratympanic steroid injections showed a better audiologic outcome (improvement, 26.1 ± 24.3 vs. 15.7 ± 22.1 dB; P = 0.000) than those who had not (n = 429). In conclusion, a higher degree of hearing loss at the initial presentation indicates a poorer prognosis. Salvage intratympanic steroid injection therapy may improve the hearing of patients with profound idiopathic sudden sensorineural hearing loss after the failure of systemic steroid therapy.

    Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. MS involves different regions of the central nervous system in different periods, and causes demyelination. MS is a neuromotor disorder which progresses with remissions and relapses. Symptoms of MS may regress completely or heal after the relapses leaving sequelae. Sudden sensorinerural hearing loss (SSHL) is hearing loss of 30 dB or more over at least three contiguous audiometric frequencies that develops over a period of a few hours to 3 days. In 4-10 % of the MS patients, sensorineural hearing loss occurs between relapses or remissions. In this case, audiotory brainstem response (ABR) test is the most appropriate test for the diagnosis of sensorineural hearing loss in MS patients. In this article, we will discuss a patient diagnosed as MS who presented with sudden sensorineural hearing loss during the remission of the disease.

    A case of unilateral sensorineural hearing loss of the left ear after carbon monoxide intoxication was presented. The diagnosis was based upon an interview, medical examinations and audiometric investigations. Results of diagnostic evaluations, clinical presentation and treatment were discussed. Hearing improvement was obtained after 6 days of treatment and normal hearing returned after 14 days. Patients who suffer from CO intoxication are at risk of hearing impairment, therefore, there is a need for audiometric follow up in these patients.

    Full Text Available Sudden sensorineural hearing loss (SNHL is an emergency in otolaryngological practice. The exact cause, in most of the cases cannot be found. A triad of vascular, viral, and membrane rupture are the known theories for the causation of sudden SNHL. Now various autoimmune disorders have also been suggested to play a role in the pathogenesis. Autoimmune inner ear disease in human being is an uncommon, but a distinct clinical entity. The diagnosis of the inner ear autoimmune disorder depends mainly on relatively distinct clinical course, immune laboratory tests and treatment response. The clinical picture usually consists of bilateral SNHL, bilateral reduced vestibular loss and symptoms of pressure with tinnitus and rarely tissue destruction of middle and external ear. Systemic scleroderma is an aggressive multi-system and multistage connective tissue disorder with high mortality. It is characterized by proliferative vascular lesion and marked deposition of collagen in various tissues and organs. Responses to immunosuppressive drugs are cited as evidence of an autoimmune process.

    Full Text Available Abstract Background Climatic or meteorological condition changes have been implicated in the pathogenesis of Idiopathic Sudden Sensorineural Hearing Loss (ISSHL. We investigated the seasonal distribution of ISSHL and evaluated the influence of meteorological parameters (such as temperature, humidity, and atmospheric pressure, their variation and covariation on the incidence of the disease. Methods A total of 82 cases of ISSHL, admitted to our department over a five-year period, were enrolled in the study. Seasonal distribution of the disease was investigated by dividing the year in four seasons. Meteorological data included daily values of 13 distinct parameters recorded at the meteorological station of the University of Ioannina during this period. A relationship between each meteorological variable and the incidence of ISSHL was investigated by applying (χ2 test on data from 13 contingency tables as well as by using logistic regression and t-test approaches. In addition, the influence of different weather types on the incidence of ISSHL was investigated using Cluster Analysis in order to create eight clusters (weather types characteristic for the prefecture of Ioannina. Results The results of the study could not indicate any seasonal distribution of the disease. The incidence of ISSHL could not be significantly correlated either to any distinct meteorological parameter or to any specific weather type. Conclusions Meteorological conditions, such as those dominating in the Northwestern Greece, and/or their changes, have no proven effect on the incidence of ISSHL.

    Lassa fever (LF) is a viral hemorrhagic disease which affects one-fourth to two million people annually with the fatality rate of about 10,000. It is associated with sensorineural hearing loss (SNHL) usually at the convalescent stage. Recently, cases of SNHL at the acute phase have been reported. This study was done to further investigate the incidence and features of SNHL in acute phase of LF. It is a prospective case-control study of LF patients seen with acute SNHL conducted between July 2007 and April 2009 at Irrua Specialist Teaching Hospital Nigeria. The diagnosis of acute LF was based on the clinical features and detection of IgM antibodies and/or positive Lassa virus-specific reverse transcriptase-polymerase chain reaction using primers S36+ and LVS 339 while SNHL was diagnosed clinically and confirmed with PTA and speech discrimination tests. Patients with other acute febrile illnesses were used as control. Statistical analysis was done using SPSS version 11 and Fisher's exact test while level of significance was set at p 0.05). The incidence of SNHL in LF infection is about 13.5% and could be a reflection of a worse disease process. There is possibility of direct viral invasion aside immunological reaction as a causative mechanism.

    Among 95 patients with sudden sensorineural hearing loss who received inpatient treatment at our hospital within the 27-month period between October 2009 and December 2011, those in whom hearing loss was aggravated after diagnosis were compared with a control group. Hearing loss aggravation was defined as a decrease by 10 dB or more in the mean hearing threshold at 5 frequencies from 250 to 4,000 Hz or decrease of 15 dB or more in the hearing threshold at 2 consecutive frequencies. Hearing loss was aggravated after diagnosis in 22 (23.2%) of the 95 patients, showing a similar tendency to that previously reported. Although the grades of hearing loss in these patients were higher than those in 73 control group patients, according to the sudden hearing loss severity classification, their outcomes were favorable. The hearing loss aggravation group consisted of those with steroid-dependent hearing loss (6) and those who had undergone perilymphatic fistula repair (4), in addition to a large number of patients with idiopathic hearing loss, including suspicious perilymphatic fistula (10). When hearing loss becomes aggravated after the diagnosis of sudden sensorineural hearing loss, it may be important to determine the most appropriate approach in each case, such as a careful and gradual decrease in the adenocortical steroid dose and the consideration of perilymphatic fistula repair.

    Idiopathic sudden sensorineural hearing loss (ISSHL) is the newest indication approved by the Undersea and Hyperbaric Medical Society's Hyperbaric Oxygen Therapy Committee. Idiopathic sudden sensorineural hearing loss appears to be characterized by hypoxia in the perilymph and therefore the scala tympani and the organ of Corti. A review of the literature reveals more than 100 publications evaluating the use of hyperbaric oxygen (HBO2) for the treatment of ISSHL, including eight randomized controlled trials. The best and most consistent results are obtained when HBO2 is initiated within two weeks of symptom onset and combined with corticosteroid treatment. The average hearing gain is 19.3 dB for moderate hearing loss and 37.7 dB for severe cases. This improvement brings hearing deficits from the moderate/severe range into the slight/no impairment range. This is a significant gain that can markedly improve a patient's quality of life, both clinically and functionally.

    Sudden sensorineural hearing loss following non-otologic surgery is a rare event described in the medical literature. Cardiopulmonary bypass surgery is most commonly associated with this type of hearing loss. Our case report and review of the literature describe two cases with postoperative hearing loss - neither of which are cardiac surgeries - making them exceedingly rare in the medical literature. Regardless of the rarity of this unfortunate event, the possibility for permanent hearing loss is a potentially devastating unanticipated complication and one that all surgeons should be aware.

    Acute low-tone sensorineural hearing loss (ALHL) is a special type of sudden sensorineural hearing loss, which arises growing concern in clinical practice in recent years. Its clinical manifestations are sudden drop of low-frequency hearing without obvious causes, normal hearing of high-frequency area, no vertigo seizures or spontaneous eye shake, and normal auditory brainstem response (ABR). The disease seems to be related to endolymphatic hydrops, topical ischemic injury, immune factors and so on. Glucocorticoid treatment is very effective with good prognosis. Progression and recurrence of ALHL may be associated with Meniere’s disease.%急性低频感音神经性听力损失(ALHL)是近年来逐渐引起临床关注的一种特殊类型的突发性感音神经性耳聋。临床表现为无明显诱因的低频听力突发性下降,高频区听力正常,不伴眩晕发作和自发性眼震,听性脑干反应正常。其发病机制可能与内淋巴积水、局部缺血损伤、免疫等有关。激素治疗对其有效,预后良好。ALHL的病情进展和复发情况可能与梅尼埃病有一定的关联。

  7. Isolated Sensorineural Hearing Loss as a Sequela after Lightning Strike

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a lightning strike, serious burns on the left ear, behind the ear, and on the chest and neck. She also had in her left ear 108 dB hearing loss with irregular central perforation and in her right ear 52 dB sensorineural hearing loss. There was no hearing loss before the strike. A hearing aid was recommended for the right ear and good care and follow-up were recommended for the left ear. A lightning strike can cause serious audiological damage. Therefore, it is necessary to make a careful audiovestibular evaluation of the patients. Although there exist rarely healed cases from sensorineural hearing loss after lightning strike in literature, in our case hearing loss occurred bilaterally and then it healed unilaterally. This condition is quite rare in literature.

    Associations between hearing and blood lipids have been the focus of scientific inquiry for more than 50 years. The aim of the present study is to evaluate the association between hyperlipidaemia among patients presented with sudden sensorineural hearing loss compared to normal controls. A case control study concerned with 22 patients presented with sudden sensorineural hearing loss who underwent lipid profile evaluation. The lipid profile of these patients was compared with corresponding results of 55 age matched persons (volunteers) with normal hearing. These patients were collected from the Out Patient Department of ENT at Al-Jamhory Teaching Hospital, Mosul/Iraq and private clinic of the author for the period from February 2011 to July 2013. The average age of patients was 44.7 years with a range of 26-65 years. The peak age incidence was in the 5(th) decade of life. The study included 11 male patients (50 %) and 11 females (50 %). Meanwhile, the average age of the control group was 41.7 years with 25 (45.5 %) males and 30 (54.5 %) females. Statistical analysis showed that there was significant difference between the means of lipid profile and blood sugar of the patients and the control group apart from HDL where there was no significant difference. In conclusion, hyperlipidemia seems to be significantly associated with the occurrence of sudden sensorineural hearing loss according to this study.

    Full Text Available Sudden sensorineural hearing loss is defined as a loss of at least 30 dB in three contiguous frequencies over a period of three days or less. In the present study a client with sudden hearing loss post hypothyroidism is discussed. A 56 year old client reported of awakening from sleep due to ear fullness along with severe tinnitus and experienced reduced hearing sensitivity in the right ear. The client had a history of hypothyroidism and was under medication for the same. The successive audiological investigations revealed that there was no improvement from prescribed medications, even with early identification and intervention. For better treatment outcomes correct identification of the cause as well as application of cause based treatment procedure is essential. Endocrine disorder is said to be one of the causes for sudden sensorineural hearing loss and one among this disorder is hypothyroidism. The present study aimed to throw a light on this aspect by giving a detailed case report of the client who suffered sudden sensorineural hearing loss which is suspected to be a long term effect of hypothyroidism.

    Introduction Head sense position is coordinated by sensory activity of the vestibular system, located in the inner ear. Children with sensorineural hearing loss may show changes in the vestibular system as a result of injury to the inner ear, which can alter the sense of head position in this population. Aim Analyze the head alignment in students with normal hearing and students with sensorineural hearing loss and compare the data between groups. Methods This prospective cross-sectional study examined the head alignment of 96 students, 48 with normal hearing and 48 with sensorineural hearing loss, aged between 7 and 18 years. The analysis of head alignment occurred through postural assessment performed according to the criteria proposed by Kendall et al. For data analysis we used the chi-square test or Fisher exact test. Results The students with hearing loss had a higher occurrence of changes in the alignment of the head than normally hearing students (p < 0.001). Forward head posture was the type of postural change observed most, occurring in greater proportion in children with hearing loss (p < 0.001), followed by the side slope head posture (p < 0.001). Conclusion Children with sensorineural hearing loss showed more changes in the head posture compared with children with normal hearing. PMID:25992037

    Full Text Available Background: Among patients who have sensorineural hearing loss of unknown etiology, diabetes is one of the diseases to be routinely investigated. The relationship between diabetes mellitus and hearing loss is still controversial. The purpose of this study was to examine the prevalence of sensorineural hearing loss in patients with insulin-dependent diabetes mellitus (IDDM compared to control group.Methods: In a cross-sectional study pure tone audiometry (PTA and speech audiometry was performed in 62 patients with insulin-dependent diabetes mellitus (IDDM, aged under 40 years, and in 62 randomly selected age-matched non-diabetic control subjects. Subjects with otological and other metabolic diseases were excluded from the study. We applied the SPSS.10 statistical analysis software Chi-square and student's test. Results: Statistical analysis showed that the hearing of the diabetic patients were significantly worsen than the control subjects. The hearing level tended to be worsen in the diabetic patients than that in control subjects, but the differences were statistically significant only at frequencies of 250,500, 4000 and 8000 Hz p>0.05(. There wasn't statistical significant difference between sex in two study groups p>0.05(. The mean duration of diabetes was no statistically significant with hearing loss p>0.05(. The frequency of complications such as retinopathy, nephropathy, and neuropathy in the diabetic groups had no correlation with speech threshold (p>0.05(.‏ There were no significant differences between speech reception threshold, speech discrimination score and acoustic reflex in two groups.Conclusions: We conclude that type I diabetes mellitus can cause sensorineural hearing loss.

    A 33-year-old man developed profound sudden onset right-sided hearing loss with tinnitus and vertigo, within 24 h of pretravel rabies vaccination. There was no history of upper respiratory tract infection, systemic illness, ototoxic medication or trauma, and normal otoscopic examination. Pure tone audiograms (PTA) demonstrated right-sided sensorineural hearing loss (thresholds 90-100 dB) and normal left-sided hearing. MRI internal acoustic meatus, viral serology (hepatitis B, C, HIV and cytomegalovirus) and syphilis screen were normal. Positive Epstein-Barr virus IgG, viral capsid IgG and anticochlear antibodies (anti-HSP-70) were noted. Initial treatment involved a course of high-dose oral prednisolone and acyclovir. Repeat PTAs after 12 days of treatment showed a small improvement in hearing thresholds. Salvage intratympanic steroid injections were attempted but failed to improve hearing further. Sudden onset sensorineural hearing loss (SSNHL) is an uncommon but frightening experience for patients. This is the first report of SSNHL following rabies immunisation in an adult.

    The management of sudden sensorineural hearing loss following spinal anesthesia is currently an open problem. Several strategies have been used with variable results and, to the best of our knowledge, there are no prior accounts in the literature on the use of hyperbaric oxygen therapy in the treatment of this complication. We report two cases of acute onset of unilateral hearing loss after spinal anesthesia, with significantly improved results after hyperbaric oxygen therapy. A hypothesis on the possible mechanism behind this complication is discussed. A relation is established between hyperbaric oxygen therapy and this hypothetical mechanism, in order to explain successful results in the reported cases.

    2016-01-01

    Full Text Available Multiple sclerosis (MS is the most common demyelinating disease of the central nervous system. MS is a neuromotor disorder which progresses with remissions and relapsing periods. Symptoms of MS plaques may regress completely or heal by leaving sequelae. Symptomatology of MS may be very variable. These symptoms usually show variations depending on the localization of demyelinated plaques in the central nervous system. In this case, we are presenting a case of sudden sensorineural hearing loss in alternate ears with magnetic resonance images suggestive of demyelinating disorders. These hearing losses are improved completely as disease has remission and relapsing periods.

    The study purpose was to determine the efficacy of steroids, volume expanders and antivirals in the management of idiopathic sudden sensory neural hearing loss and to establish importance of early medical intervention. In this prospective study, thirty-four patients presenting with idiopathic sudden hearing loss of 30 db or more were enrolled in study group between 2005 and 2009. Patient variables as they related to recovery were studied and include patient age, time to onset of therapy, status of contralateral ear, presence of diabetes, severity of hearing loss, pattern of hearing loss in audiogram and presence of associated symptoms, (tinnitus, vertigo). Treatment protocol with intravenous hydrocortisone, intravenous dextran and oral anti-viral agent was followed. Pre-treatment and post-treatment pure tone average was analyzed. With combination therapy the overall improvement in pure tone threshold was seen in 27 patients (79.4%). A statistically significant association was found between the time at which medical intervention was started and hearing improvement. Early intervention in patients presenting before 3 days has given 77.8% complete type 1 recovery Idiopathic sudden sensory neural hearing loss is a medical emergency. It should not be misdiagnosed. Early detection and management with volume expanders, steroids and antivirals will improve the chances of complete recovery.

    Objective To identify the characteristics and values of audiometric testing in acute low-tone sen-sorineural hearing loss in improvig diagnosis and treatment. Methods Maudiometric and imaging results were reviewed for patients with acute low-tone sensorineural hearing loss admitted to our hospital from July 2008 to May 2010. Results Of the 15 patients studied, an apparent causative factor was identified in 9 (60.0%). In 8 patients (53.3%) there was recurrence of hearing loss during follow up. No difference was found between male and female patients regarding cause and recurrence of hearing loss. Electrocochleogram was performed in 8 patients, in whom 5 (62.5%) showed abnormal -SP/ AP ratios. Conclusion The examinations including pure tone audiometry, electrocochleogram (ECochG), DPOAE and ABR have more significance than others in acute low frequency sensorineural hearing loss. Studies are needed for ideal management of this condition, which is probably associated with the social stress. Its pathophysiology likely involves an array of abnormalities including endolymphatic hydrops, autoimmune disorders and autonomic nervous system dysfunction.%目的 明确各项听力学检查在急性低频感音神经性听力损失诊断及研究中的意义,以指导该病的诊断和治疗.方法 对2008年7月至2010年5月在本科就诊的急性低频感音神经性听力损失患者的临床听力学检查进行了回顾性分析.结果 在所有15例患者中有9人(60.0%)有明显诱发因素.在随访期间,有8例(53.3%)出现复发.男女两性无诱发因素和复发率差异.8例患者进行了耳蜗电图的检查,有5例(62.5%)-SP/AP(总合电位/动作电位)检查异常.结论 纯音测听、耳蜗电图、DPOAE(畸变产物耳声发射)、ABR(听性脑干电位)在急性低频感音神经性听力损失诊断及研究中意义较大.其发病很可能与生活压力事件相关,病因可能是膜迷路积水、自身免疫性机制和自主神经功能紊乱等因素的综合作用.

Initially, pure-tone audiometry showed a profound sensorineural hearing loss in the right ear and mild sensorineural hearing loss in the left ear (of note, the hearing was normal prior to the episode). Following resolution of the patient's symptoms during a roller coaster ride, pure-tone audiometry showed normal hearing thresholds in both ears. Sudden sensorineural hearing loss is a symptom of cochlear injury and the mechanism of the patient's symptoms was attributed to a patent cochlear aqueduct.

    Full Text Available The role of preexisting sensorineural hearing impairment on the risk for sudden sensorineural hearing loss (SSHL is still unclear. In this study, we aimed to assess the risk of SSHL in patients with common preexisting sensorineural hearing impairment using population-based data.A population-based case-control study design was used to analyze claims data between January 2001 and December 2011 obtained from the Taiwan National Health Insurance Research Database. The cases consisted of 514 patients with SSHL and the controls were frequency matched to 2,570 cases by sex, 10-year age group, and year of index date. Common sensorineural hearing impairments were retrospectively assessed in the cases and controls. Associations between sensorineural hearing impairment and risk of SSHL were evaluated using unconditional univariate and multivariate logistic regression analyses.The mean age for the 3,084 study subjects was 53.1 years (standard deviation, S.D. = 15.6. Of the 514 cases, 49 (9.5% had sensorineural hearing impairment while only 44 (1.7% of the 2,570 controls had the same condition. Univariate logistic regression analyses indicated that preexisting sensorineural hearing impairment was significantly associated with SSHL (odds ratio, OR = 6.05, p < 0.001. Other comorbidities including hypertension, diabetes mellitus, and hyperlipidemia also showed significant associations with SSHL. Similar results were obtained when the association between SSHL and sensorineural hearing impairment was adjusted with either all the covariates (adjusted OR = 6.22, p < 0.001 or with only those selected using a backward elimination procedure (adjusted OR = 6.20, p < 0.001.Results from this population-based case-control study revealed that common sensorineural hearing impairment might be a novel risk factor for SSHL.

    Comorbidity of sensorineural hearing deficits and both depressive states and dementia in late life provided the rationale for this investigation. Cognitively intact geriatric major depressives (n = 43) were assessed for depressive symptoms, cognitive performance, and delusions while symptomatic, and following treatment, when audiometry was performed. Late-onset depressed patients (LOD) had more hearing deficits compared to early-onset depressives (EOD). Age at onset of depression was found to have a significant effect on Pure-Tone Thresholds for 0.5-4.0 kHz and on Word Recognition in Noise in the better ear (0.001 hearing loss and both the course of geriatric depression and its relationship to dementia.

    Full Text Available Aim and Objective: To investigate saccular damage in patients with sudden sensorineural hearing loss (SSNHL with or without vertigo and to evaluate the saccular damage according to the hearing loss and presence or absence of vertigo. Materials and Methods: All tests done in this study were performed in the audio vestibular unit of ENT department from September 2009 to November 2010. Statistical Analysis Used: The association between the severity of hearing loss and changes in the vestibular evoked myogenic potential (VEMP recordings were assessed using descriptive statistics. The pattern of VEMP in different diseases and also the behavior of VEMP in presence or absence of vertigo were evaluated using SPSS 15. Results: Among 27 patients there were 11 cases of idiopathic SSNHL. Out of nine unaffected ears, 88% had normal and 12% had absent VEMP. Whereas out of 13 affected ears, only 53.9% had normal VEMP. Among all the 54 ears, 17 ears had normal hearing. In this group 76.47% had normal VEMP. The group with hearing loss > 90 dB had 61.53% absent VEMP. Conclusions: In patients with unilateral SSNHL, there was a tendency for the affected ear to have absent VEMP indicating the saccular involvement. The extent of saccular damage did not correspond to the amount of hearing loss or presence or absence of vertigo.

    The purpose of this study was to investigate the effectiveness of intratympanic steroids in patients with idiopathic sudden sensorineural hearing loss who did not respond to initial systemic steroid therapy. This retrospective study involved 51 patients, who did not respond to systemic steroids as a first-line treatment. Initial systemic steroid therapy consisted of administration of methylprednisolon intravenously (250 mg) at the first day and followed by orally (1 mg/kg) tapering for 14 days. Twenty-one patients accepted intratympanic treatment, and the remaining 30 patients who refused intratympanic treatment were evaluated as the control group. Steroids (dexamethasone drops, 1 mg/mL) were administered through a ventilation tube. Hearing was assessed immediately before treatment and 2 months after treatment. Recovery of hearing was defined as an improvement of >20 dB in the pure tone average. We tested 250, 500, 1,000, 2,000, 4,000, and 8,000 Hz frequencies for the pure tone audiometric evaluation. Statistically Student's t test, Mann-Whitney U test, Chi-squared and Fisher's exact tests were used. The pure tone average improved in 47.6% of the intratympanic group and in 10% of the control group (p = 0.002), with pure tone average improvements of 19.9 ± 16.5 and 4.76 ± 9.6 dB in the intratympanic and control groups, respectively. When the hearing threshold at each frequency was analyzed, improvements at all frequencies were significantly greater in the intratympanic steroid group when compared with the control group (p sudden sensorineural hearing loss in patients, who are refractory to primary systemic steroid therapy.

    Full Text Available Sudden Sensorineural Hearing Loss (SSHL is dreaded condition affecting many individuals around the world due to its sudden appearance and inconspicuous nature of disease. More than 50% recover spontaneously, but timely identification of cause and treatment can help the patient immensely. METHODS In our study, we prospectively analyzed twenty patients presenting with idiopathic sudden hearing loss of 30 db or more between 2010 and 2015. RESULTS Two out of 20 patients (60% showed complete improvement and 10 patients out of 13 (77% who presented with 7 days showed complete recovery. Hence, time of presentation and drugs used directly affect the outcome of the patient. CONCLUSION It can be safely concluded that early diagnosis and management is key in treatment of SSHL. Intratympanic dexamethasone with intravenous dexamethasone or oral deflazacort is used in all patients with supportive measures has helped most of our patients. Oral acyclovir was used in only one patient.

    2004-05-01

    The perceived dissonance of two simultaneous tones (a dyad) depends upon their frequency separation (in the case of two pure tones) or their fundamental frequency ratio (in the case of two harmonic complex tones). The purpose of this study was to determine whether the perceived dissonance of puretone and harmonic complex dyads is altered in the presence of sensorineural hearing (SNHL), and, if so, whether this can be explained by the reduced frequency selectivity typically associated with SNHL. Four normal-hearing and four hearing-impaired listeners evaluated the dissonance of puretone and harmonic complex dyads centered at 500 and 2000 Hz. Frequency selectivity was estimated at 500 and 2000 Hz for each listener. People with SNHL rated the dissonance of puretone dyads similarly to the normal-hearing listeners, although auditory sensitivity and frequency selectivity differed considerably between the groups. However, their ratings of harmonic complex dyads did not show the pronounced differences in dissonance as a function of fundamental frequency ratio that were observed in the normal-hearing group. The poorer frequency selectivity of these listeners may have allowed more extensive interactions to occur among harmonic components, resulting in a less clear separation of dissonance and consonance.

    Full Text Available INTRODUCTION: Idiopathic Sudden Sensorineural Hearing Loss (ISSHL is defined when a loss of at least 30 dB occurs in over 3 continuous frequencies, in up to 72 hours, of which etiology is not established, despite adequate investigation. Different types of treatment regimens have been proposed, but only glucocorticoids have shown some evidence of benefit in the literature. OBJECTIVE: To analyze whether the type of treatment or time of treatment with glucocorticoids have any influence on hearing recovery in ISSHL. METHODS: Observational retrospective cohort study. One hundred twenty-seven patients with ISSHL, treated at outpatient clinics between the years 2000 and 2010, were studied. We evaluated the prognostic correlation of the type of treatment and time to treatment with glucocorticoids and ISSHL. RESULTS: The absolute hearing gain and the relative hearing gain was as follows: 23.6 dB and 37.2%. Complete recovery was observed in 15.7% of patients, significant recovery in 27.6% and recovery in 57.5%. CONCLUSION: In this study, there was no difference between the use and nonuse of glucocorticoids in hearing improvement. However, when started within seven days after onset, the use of glucocorticoids was a factor of better prognosis.

    An endothelial dysfunction has been described in idiopathic sudden sensorineural hearing loss (ISSHL) patients. The purpose of our review was to: i) identify, evaluate and review recent research about cardiovascular risk factors involvement and signs of endothelial dysfunction in ISSHL; ii) implication of these discovering in clinical practice and future research. A Medline literature search was conducted to identify any study on the involvement of endothelial dysfunction in ISSHL, published in the English language in the last decade. The following MEDLINE search terms were used: sudden sensorineural hearing loss (SSHL) and endothelial dysfunction (text words). Additional studies were identified by hand searching the references of original articles and review articles. Studies were not excluded on the basis of the qualitative or quantitative definitions of SSHL, treatment regimens, or outcome measures. Data were extracted from included papers by a reviewer. Information on the patients, investigations, methods, interventions, and outcomes were systematically analyzed. Characteristics and results of all included studies were reviewed systematically. High levels of adhesion molecules, hyperhomocysteinemia and lower folate levels, unbalanced oxidative status, a lower value of flow-mediated dilatation of brachial artery and a reduced percentage of circulating endothelial progenitor cells in patients affected by ISSHL support the hypothesis that this syndrome should be considered as a microcirculation disorder based on endothelial dysfunction and drive clinicians to implement all the traditional strategies used for preventing cardiovascular events, to also reduce the likelihood of ISSHL occurrence.

    Background: The prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL. Methods: One hundred and thirty-six CSSNHL patients treated in Department of Otolaryngology-Head and Neck Surgery and Institute of Otolaryngology at Chinese PLA General Hospital between July 2008 and August 2015 were included in this study. These patients were analyzed for clinical characteristics, audiological characteristics, laboratory examinations, and prognostic factors. Results: Among the 136 patients (151 ears), 121 patients (121 ears, 80.1%) were diagnosed with unilaterally CSSNHL, and 15 patients (30 ears, 19.9%) with bilateral CSSNHL. The complete recovery rate of CSSNHL was 9.3%, and the overall recovery rate was 37.7%. We found that initial degree of hearing loss, onset of treatment, tinnitus, the ascending type audiogram, gender, side of hearing loss, the recorded auditory brainstem response (ABR), and distortion product otoacoustic emissions (DPOAEs) had prognostic significance. Age, ear fullness, and vertigo had no significant correlation with recovery. Furthermore, the relevant blood tests showed 30.8% of the children had abnormal white blood cell (WBC) counts, 22.1% had elevated homocysteine levels, 65.8% had high alkaline phosphatase (ALP), 33.8% had high IgE antibody levels, and 86.1% had positive cytomegalovirus (CMV) IgG antibodies. Conclusions: CSSNHL commonly occurs unilaterally and results in severe hearing loss. Initial severe hearing loss and bilateral hearing loss are negative prognostic factors for hearing recovery, while positive prognostic factors include tinnitus, gender, the ascending type audiogram, early treatment, identifiable ABR waves, and DPOAEs. Age, vertigo, and ear fullness are not correlated with the recovery. Some serologic indicators

    Profound sensorineural hearing loss (PSHL) is not uncommonly encountered in otology. In clinics, there is a high incidence of otolithic damage in patients with PSHL, but relevant reports are few. Sharing a continuous membranous structure and similar receptor cell ultrastructures, the cochlea and vestibule may be susceptible to the same harmful factors. Disorders of the inner ear may result in a variety of manifestations, including vertigo, spatial disorientation, blurred vision, impaired articulation, and hearing impairment. Considering the diversity of clinical symptoms associated with PSHL with otolithic dysfunction, it may be frequently misdiagnosed, and objective means of testing the function of otolithic organs should be recommended for hearing-impaired patients. Vestibular-evoked myogenic potentials (VEMPs) via air-conducted sound are of great importance for the diagnosis of otolithic function. Hearing devices such as cochlear implants are commonly accepted treatments for PSHL, and early identification and treatment of vestibular disorders may increase the success rate of cochlear implantation. Therefore, it is necessary to increase awareness of otolithic functional states in patients with PSHL.

    Idiopathic sudden sensorineural hearing loss (ISSNHL) is an otologic emergency with an incidence of about 5-20 per 100,000 of the population per year. There is no universally accepted standard protocol for the treatment of patients with ISSNHL. Hyperbaric oxygen therapy (HBOT), was first reported to improve the outcome following acute inner ear disorders during the late 1960s by both French and German authors. The increase in perilymph oxygenation produced by HBOT provides logical basis for the use of this treatment modality in ISSNHL. We reviewed the records of 97 cases that received HBOT for SSNHL to identify the factors that may affect the treatment outcomes. The effects of age, gender, affected ear, status of the contralateral ear, symptoms associated with hearing loss, presence of a cardiovascular disease, dyslipidemia, history of diabetes mellitus, seasonal factor, smoking, degree of hearing loss, audiogram type, medical treatments provided prior to HBOT, onset time, and number of HBOT sessions were evaluated. The mean hearing gain in all cases after the HBOT was 29.5 dB. The gains were statistically significant in the following cases: early onset of HBOT (p = 0.016), higher number of HBOT sessions (p hearing loss (p = 0.011). The success rate was significantly lower in cases with high frequency-descending audiogram configuration (p hearing loss.

    Full Text Available Celiac Disease (CD is an autoimmune disease of the small intestine characterized by the immune response against ingested gluten. This response causes characteristic damage to the villi, which in turn results in malabsorption. Clinical signs and symptoms of CD may start early in childhood or in adulthood. Some people are completely asymptomatic. The term celiac crisis is used for patients with acute-onset severe abdominal pain which is potentially fatal. Although various extraintestinal signs and symptoms have been defined in CD, there are contradictory reports regarding hearing loss. We hereby report a patient with celiac disease who was investigated for malabsorption and was diagnosed with mild to medium temporary sudden sensorineural hearing loss (SNHL.

This was a prospective clinical study of 136 consecutive patients with SSNHL divided into three groups after diagnostic evaluation: patients with defined etiology (DE, N = 13, 10%, concurrent diseases (CD, N = 63, 46.04% and idiopathic sudden sensorineural hearing loss (ISSHL, N = 60, 43.9%. Initial treatment consisted of prednisone and pentoxifylline. Clinical aspects and hearing evolution for up to 6 months were evaluated. Group CD comprised 73% of patients with metabolic decompensation in the initial evaluation and was significantly older (53.80 years than groups DE (41.93 years and ISSHL (39.13 years. Comparison of the mean initial and final hearing loss of the three groups revealed a significant hearing improvement for group CD (P = 0.001 and group ISSHL (P = 0.001. Group DE did not present a significant difference in thresholds. The clinical classification for SSNHL allows the identification of significant differences regarding age, initial and final hearing impairment and likelihood of response to therapy. Elevated age and presence of coexisting disease were associated with a greater initial hearing impact and poorer hearing recovery after 6 months. Patients with defined etiology presented a much more limited response to therapy. The occurrence of decompensated metabolic and cardiovascular diseases and the possibility of first manifestation of auto-immune disease and cerebello-pontine angle tumors justify an adequate protocol for investigation of SSNHL.

    Sudden sensorineural hearing loss (SSNHL) has several etiologies. It may be a presenting symptom of vestibular schwannoma (VS). This study aimed to establish the incidence of VS in patients with SSNHL, and we report several unusual cases among these patients. We reviewed retrospectively the charts and magnetic resonance imaging (MRI) findings of all adult patients who presented with SSNHL between 2002 and 2008. We utilized three-dimensional fast imaging with steady-state acquisition temporal MRI as a screening method. Of the 295 patients with SSNHL, VS was found in 12 (4%). All patients had intrameatal or small to medium-sized tumors. There were three cases with SSNHL in one ear and an incidental finding of intracanalicular VS in the contralateral ear. There were four cases of VS that showed good recovery from SSNHL with corticosteroid treatment. There were two cases that mimicked labyrinthitis with hearing loss and vertigo. A greater number of cases than expected of VS were detected in patients with SSNHL, as a result of increasing widespread use of MRI. Various unusual findings in these patients were identified. MRI would seem to be mandatory in all cases of SSNHL.

    The reasons behind sudden sensorineural hearing loss are mostly unknown, but viral infections, blood disorders, ototoxicity, noise trauma, autoimmune disease, acoustic tumor, and even mental stress may be related to the disease. In cases of hearing loss as a result of psychogenic factors, early diagnosis and adequate treatment under collaboration with the psychiatric department are crucial, since failure to take appropriate measures may result in permanent sequela. We report a case, with a review of the literature, of sudden unilateral sensorineural hearing loss with contralateral psychogenic hearing loss induced by gunshot noise.

    Full Text Available Sudden Sensorineural Hearing Loss (SSHNL is a clinical condition that requires immediate management. There are many treatment options, which may not always revert the hearing to normal. Not only recording the degree of hearing loss, but also establishing the concurrent dysfunction of saccule by VEMP has facilitated a new approach to treatment strategy. Recombinant tissue Plasminogen Activator ((rtPA proved its efficacy in stroke and subsequently considered an option in the management of ISSNHL. The curren t study, conducted at different centres, on 15 patients utilized rtPA. The results showed a promising trend when saccular pathology is also evident by VEMP in association with Hearing loss. We recommend use of rtPA as primary modality in cases of ISSNHL wi th Saccular involvement.

    Active middle ear implants, such as the Vibrant Soundbridge, are used as an important part in the rehabilitation of sensorineural, conductive hearing, or mixed hearing loss. The attachment of the Vibrant Soundbridge at the round window and the usage of the Vibroplasty couplers strongly expanded the application of the Vibrant Soundbridge.The Vibrant Soundbridge is developed for patients who have an intolerance to hearing aids and a moderate to profound sensorineural hearing loss. The VSB also provides an optimal solution for patients with failed middle ear reconstructions or patients with atresia. To capture the improvement with the VSB Implant with different hearing losses a literature analysis was conducted. The functional gain was analyzed for 107 patients with conductive hearing loss and for 214 patients with sensorineural hearing loss out of 14 studies.Patients with conductive and mixed hearing loss resulted in a functional gain from 30 to 58 dB with the VSB. Patients with a pure sensorineural hearing loss showed a functional gain of 23-30 dB. The VSB bone conduction threshold shift was analyzed for all studies conducted in the years between 2000 and 2009. In 11 of the 16 studies there was no significant (p=0.05) change found. In 5 studies, the pre- to post-surgical bone conduction threshold shift was less than 10 dB. None of these studies measured a threshold shift of more than 10 dB.The flexible attachment at either the long process of the incus with sensorineural hearing loss, with an conductive hearing loss at the round window or the use of Vibroplasty couplers at the oval window, head of the stapes or round window makes the VSB an extremely versatile instrument. If patients can't wear conventional hearing aids, had failed middle ear reconstructions or atresia the VSB presents, due to the significant hearing improvement in any type of hearing loss, an ideal solution.

    Abstract Introduction: Sudden sensorineural hearing loss is an unusual presenting clinical feature of systemic lupus erythematosus. Case report: We report the case of a young woman who was admitted to hospital for sudden sensorineural hearing loss and hemophagocytic syndrome which was attributed to systemic lupus erythematosus on the basis of specific renal involvement, thrombocytopenia, and consistent autoantibodies. Favorable outcome was obtained on high-dose corticosteroids, and the hearing fully recovered. Discussion: Sudden sensorineural hearing loss in systemic lupus erythematosus is seemingly more frequently associated with severe systemic involvement and antiphospholipid antibodies may be present. Although management remains empirical, the high risk of permanent hearing impairment seems to justify emergency treatment with high-dose corticosteroids. When the clinical and laboratory criteria of antiphospholipid syndrome are met, antiplatelets agents or anticoagulation therapy shall be considered. PMID:27603334

    The present study was designed to examine speech recognition in patients with sensorineural hearing loss when the temporal and spectral information in the speech signals were co-varied. Four subjects with mild to moderate sensorineural hearing loss were recruited to participate in consonant and vowel recognition tests that used speech stimuli processed through a noise-excited voeoder. The number of channels was varied between 2 and 32, which defined spectral information. The lowpass cutoff frequency of the temporal envelope extractor was varied from 1 to 512 Hz, which defined temporal information. Results indicate that performance of subjects with sensorineural heating loss varied tremendously among the subjects. For consonant recognition, patterns of relative contributions of spectral and temporal information were similar to those in normal-hearing subjects. The utility of temporal envelope information appeared to be normal in the hearing-impaired listeners. For vowel recognition, which depended predominately on spectral information, the performance plateau was achieved with numbers of channels as high as 16-24, much higher than expected, given that the frequency selectivity in patients with sensorineural hearing loss might be compromised. In order to understand the mechanisms on how hearing-impaired listeners utilize spectral and temporal cues for speech recognition, future studies that involve a large sample of patients with sensorineural hearing loss will be necessary to elucidate the relationship between frequency selectivity as well as central processing capability and speech recognition performance using vocoded signals.

    Sudden deafness is acute onset of impaired hearing which develops within hours to few days. The commonly accepted audiometric criterion is a decrease in hearing of ≥ 30 dB, affecting at least three consecutive frequencies. Hearing loss is thought to involve several causative factors, including internal ear circulatory disturbances. We report the case of a female with an internal carotid artery (ICA) pseudoaneurysm in the distal cervical tract and unilateral sudden sensorineural hearing loss (SSNHL). As putative risk vascular factor, the patient had history of migraine since youth. Extensive screenings for autoimmune, rheumatic diseases, virological, and microbiological infections were negative. The patient denied recent cervical trauma. Furosemide and oral prednisone were given with initial benefit and withdrawn in 3 weeks. The patient experienced short-lasting episodes of headache, tinnitus, vertigo. Five weeks after first onset, she underwent magnetic resonance imaging (MRI) angiogram which revealed fusiform dilatation of left ICA in the cervical tract. It can be proposed, but it remains to be proved, that the pseudoaneurysm of the cervical ICA plays a role in the patient SSNHL in relation to turbulent flow or thromboembolism of branches to the inner ear.

    There are several factors (viral infections, metabolic and ototoxic disorders etc.) accused for the development of sudden sensorineural hearing loss. Some prognostic factors (late onset of treatment etc.) had been evaluated in the literature. There is no sufficient data on the effect of routine laboratory parameters on the development and/or prognosis of sudden sensorineural hearing loss. The aim of this study is to investigate the effects of routine blood chemistry and hematological parameters on the development and prognosis of disease in patients with idiopathic sudden sensorineural hearing loss. One hundred and forty-seven patients with the diagnosis of idiopathic sudden sensorineural hearing loss followed up during the periods of 2000-2010 years were included in this study. One hundred and three septoplasty patients with no otologic complaints were enrolled as control group. Following the clinical and demographic evaluations, patients with idiopathic sudden sensorineural hearing loss and control groups, and patients treated successfully and patients with poor outcome were compared with each other. Data were analyzed by T test. All hematological and biochemical parameters were compared. Hemoglobin, hematocrit, white blood cell count, total and direct bilirubin, fasting blood glucose level and aspartate aminotransferase were significantly different between idiopathic sudden sensorineural hearing loss and control groups. There was no significantly different parameter between patients treated successfully and patients with poor outcome. Hemoglobin, hematocrit, white blood cell count, total and direct bilirubin, fasting blood glucose level and AST all can be risk factors for SHL, or they can be the result of undetermined pathology, because these parameters have no effect on the prognosis. Other routine parameters seem to have no effect on the development and/or prognosis of idiopathic sudden sensorineural hearing loss.

    Full Text Available To evaluate the impact of gentamicin exposure on sensorineural hearing loss (SNHL in very low birth weight (VLBW infants.Exposure to gentamicin was determined in infants born between 1993 and 2010 at a gestational age < 32 weeks and/or with a birthweight < 1500 g, who presented with SNHL during the first 5 years of life. For each case, we selected two controls matched for gender, gestational age, birthweight, and year of birth.We identified 25 infants affected by SNHL, leading to an incidence of SNHL of 1.58% in our population of VLBW infants. The proportion of infants treated with gentamicin was 76% in the study group and 70% in controls (p = 0.78. The total cumulated dose of gentamicin administered did not differ between the study group (median 10.2 mg/kg, Q1-Q3 1.6-13.2 and the control group (median 7.9 mg/kg, Q1-Q3 0-12.8, p = 0.47. The median duration of gentamicin treatment was 3 days both in the study group and the control group (p = 0.58. Maximum predicted trough serum levels of gentamicin, cumulative area under the curve and gentamicin clearance were not different between cases and controls.The impact of gentamicin on SNHL can be minimized with treatments of short duration, monitoring of blood levels and dose adjustment.

    Sudden sensorineural hearing loss is one of the otological emergencies whose pathogenesis is uncertain and associated with total or partial loss of hearing function. The aim of this study was to investigate whether the hyperbaric oxygen therapy starting time affects the management of sudden sensorineural hearing loss. Fifty-nine patients with sudden sensorineural hearing loss admitted to our clinic between 2008 and 2012 were retrospectively included in this study. All patients received hyperbaric oxygen therapy. In addition, each patient received intravenous piracetam and 37 patients received steroid therapy. Hyperbaric oxygen therapy was initiated between 1 and 7 days with 20 patients determined as Group A, between 8 and 14 days with 25 patients determined as Group B and between 15 and 28 days with 14 patients determined as Group C. Hearing gains of these three groups were statistically evaluated. Each of them showed statistically significant improvement. Lowest hearing gain was observed in Group C and the gain of this group was statistically less than the other two groups. There was no significant difference between the hearing gains of the Group A and Group B. Starting hyperbaric oxygen therapy in patients with sudden sensorineural hearing loss within the first 14 days has positive effect on the prognosis of the disease.

    Because inner ear organs are interconnected through the endolymph and surrounding endolymphatic membrane, the patients with sudden sensorineural hearing loss (SSNHL) often complain of vertigo. In this study, we report a patient with SSNHL accompanied by persistent positional vertigo, and serial findings of head-roll tests are described. At acute stage, head-roll test showed persistent geotropic direction-changing positional nystagmus (DCPN), which led to a diagnosis of SSNHL and ipsilateral light cupula. Although vertigo symptom gradually improved, positional vertigo lasted for more than 3 weeks. At this chronic stage, persistent apogeotropic DCPN was observed in a head roll test, which led to a diagnosis of the heavy cupula. Although the mechanism for the conversion of nystagmus direction from geotropic to apogeotropic persistent DCPN is unclear, the change of specific gravity of the endolymph might be one of the plausible hypothetical explanations.

    This study reports an unusual case in which myelodysplastic syndrome presented bilateral sudden sensorineural hearing loss as the first symptom of the disease. The aural symptoms and signs such as tinnitus, dizziness, and hearing impairment of a hematologic disease are common. However, sudden hearing loss as the first manifestation of a hematologic disease is extremely rare. A 76-year-old woman presented with bilateral sudden hearing loss. The patient was found to have myelodysplastic syndrome during a workup for her hearing loss. Unfortunately, the patient's hearing loss did not improve after the medical treatment.

    Full Text Available OBJECTIVES: We used hearing tests and peripheral blood sample analyses to characterize the pathology of idiopathic sudden sensorineural hearing loss (ISSNHL and to identify possible prognostic factors for predicting recovery of hearing loss. STUDY DESIGN: A retrospective, multicenter trial was conducted. METHODS: Two hundred three patients examined within 7 days after the onset of ISSNHL received prednisone with lipo-prostaglandin E1. Pure-tone auditory tests were performed before and after treatment with these drugs. Blood tests were performed on blood samples collected during the patients' initial visit to our clinic. RESULTS: In all patients, elevated white blood cell (WBC counts, fasting blood sugar levels, HgbA1c, and erythrocyte sedimentation rate (ESR significantly correlated with high hearing threshold measurements obtained on the initial visit. High fibrinogen levels, WBC counts, ESR, and low concentrations of fibrinogen degradation products (FDP were associated with lower hearing recovery rates. Additionally, different audiogram shapes correlated with different blood test factors, indicating that different pathologies were involved. CONCLUSIONS: High fibrinogen levels measured within seven days after ISSNHL onset correlated with poorer hearing recovery. This may be a consequence of ischemia or infections in the inner ear. The high WBC counts also observed may therefore reflect an immune response to inner ear damage induced by ischemic changes or infections. Our data indicate that therapeutic strategies should be selected based on the timing of initial treatment relative to ISSNHL onset.

    The aim of this study is to analyze the clinical characteristics and treatment of sudden sensorineural hearing loss (SSNHL) patients with vestibular schwannoma (VS). The clinical features of the VS patients were explored by retrospectively analyzing the clinical data from 542 cases of SSNHL patients between January 2008 and March 2013. There were 10 cases (10 ears) diagnosed with VS in 542 cases of SSNHL patients (10 ears, 1.85 %), 3 males, 7 females, with a range of 28-57 years. Among all the cases, eight patients with abnormal ABR, ten with ear ipsilateral stapedius reflexes which were completely not elicited and seven patients with healthy ear contralateral stapedius reflexes which were completely not elicited. Neuromas were classified by Koos grades according to size (8 of grade I, 1 of grade II, 1 of grade IV). Eight small VS  patients were taken waiting and MRI therapy strategies. Meanwhile, we used glucocorticoid treatment and timely and short-term medication to improve the microcirculation of the inner ear for these patients. And four cases' hearing was improved. Some vestibular schwannomas have SSNHL as initial symptoms, especially the small ones in internal auditory canal. To prevent misdiagnosis or leak-diagnosis, MRI should be performed as a routine test for SSNHL, and ABR is sometimes necessary for SSNHL patients. It is also necessary to give appropriate treatment to protect hearing of the small vestibular schwannoma patients whose first symptoms are diagnosed as SSNHL in acute phase.

    Abstract Poststroke sudden sensorineural hearing loss (SSNHL) can hinder communication between patients and healthcare professionals, thereby restricting participation in rehabilitation programs and limiting improvements in physical performance. However, the relationship between stroke and SSNHL remains unclear. This study employed a nationwide population-based dataset to investigate the relationship between stroke and SSNHL. The Taiwan Longitudinal Health Insurance Database was used to compile data from 11,115 stroke patients and a comparison cohort of 33,345 matched nonstroke enrollees. Each patient was followed for 5 years to identify new-onset SSNHL. Stratified Cox proportional-hazard regression analysis was used to examine the association of stroke with subsequent SSNHL. Among the 44,460 patients, 66 patients (55,378 person-years) from the stroke cohort and 105 patients (166,586 person-years) from the comparison cohort were diagnosed with SSNHL. The incidence of SSNHL was approximately twice as high among stroke patients than among nonstroke patients (1.19 and 0.63/1000 person-years, respectively). Stroke patients had a 71% increased risk of SSNHL, compared with nonstroke patients (adjusted hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.24–2.36). We also observed a remarkable increase in risk of SSNHL in stroke patients within 1-year of follow-up (adjusted HR 5.65, 95% CI 3.07–10.41) or under steroid therapy during hospitalization (adjusted HR 5.14, 95% CI 2.08–12.75). Patients with stroke had a higher risk of subsequent SSNHL compared with patients without stroke. In particular, stroke patients within 1-year follow-up and those undergoing steroid therapy during hospitalization should be treated with the utmost caution, considering that the risk of SSNHL increases by more than 5-fold.

    The phosphodiesterase 4D (PDE4D) gene has been reported as a risk gene for ischemic stroke. The vascular factors are between the hypothesized etiologies of sudden sensorineural hearing loss (SSNHL), and this genetic effect might be attributed for its role in SSNHL. We hypothesized that genetic variants of the PDE4D gene are associated with susceptibility to SSNHL. We conducted a case-control study with 362 SSNHL cases and 209 controls. Three single nucleotide polymorphisms (SNPs) were selected. The genotypes were determined using TaqMan technology. Hardy-Weinberg equilibrium (HWE) was tested for each SNP, and genetic effects were evaluated according to three inheritance modes. We carried out sex-specific analysis to analyze the overall data. All three SNPs were in HWE. When subjects were stratified by sex, the genetic effect was only evident in females but not in males. The TT genotype of rs702553 exhibited an adjusted odds ratio (OR) of 3.83 (95 % confidence interval = 1.46-11.18) (p = 0.006) in female SSNHL. The TT genotype of SNP rs702553 was associated with female SSNHL under the recessive model (p = 0.004, OR 3.70). In multivariate logistic regression analysis, TT genotype of rs702553 was significantly associated with female SSNHL (p = 0.0043, OR 3.70). These results suggest that PDE4D gene polymorphisms influence the susceptibility for the development of SSNHL in the southern Taiwanese female population.

    Full Text Available Background: Endothelial dysfunction probably has a role in the etiology of sudden sensorineural hearing loss (SSNHL. The aim of this study was determining of the relationship between endothelial dysfunction and SSNHL. Materials and Methods: In a case-control study, 30 patients with SSNHL and 30 otherwise healthy age and sex-matched controls were studied. Demographic data gathered included age, gender, family history of SSNHL, and history of smoking, cardiovascular disease, hypertension, diabetes, and dyslipidemia. Laboratory data included measurement of hemoglobin, fasting blood sugar (FBS and lipid profile. Endothelial function was assessed by measuring flow-mediated dilation (FMD. Results: The two groups were the same in age (47.9 ± 9.3 and 48.1 ± 9.6 years, P = 0.946 with female/male ratio of 1:1 in both groups. Diabetes and dyslipidemia were more frequent in patients than controls (20% vs. 0%, P = 0.024. Brachial artery diameter was greater in patients than controls before (4.24 ± 0.39 vs. 3.84 ± 0.23 mm, P < 0.001 and after ischemia (4.51 ± 0.43 vs. 4.28 ± 0.27 mm, P = 0.020, but FMD was lower in patients than controls (6.21 ± 3.0 vs. 11.52 ± 2.30%, P < 0.001. Binary logistic regression analysis showed that FMD was associated with SSNHL independent from FBS and lipid profile (odds ratio [95% confidence interval] =0.439 [0.260-0.740], P = 0.002. Conclusion: Endothelial dysfunction, among other cardiovascular risk factors, is associated with SSNHL.

    The objective of this study is to investigate the clinical characteristics of successive bilateral sudden sensorineural hearing loss (SSNHL) with an interval of more than 1 year to aid the evaluation and management of successive bilateral SSNHL (BSSNHL). 14 successive BSSNHL patients and 118 unilateral SSNHL patients with severe and profound hearing loss were reviewed retrospectively. Information about successive BSSNHL was collected included demographics, the intervals between the attacks of bilateral ears, the past medical history, inducing factors, accompanying symptoms, pure-tone tests, blood tests, b-ultrasound examinations of vertebral artery and carotid artery, and medical interventions. And the comparison of improvement rate was made between successive BSSNHL and unilateral SSNHL. SPSS 15.0 was used to analyze the data. In successive BSSNHL, there were six males and eight females; the average aged was 49.86 ± 15.45 years (20-73 years). The interval of the two attacks was 11.43 ± 12.07 years (1-50 years) on average. The onset of treatment was 18.86 ± 12.71 days. Tinnitus was seen in 100 % of the patients, followed by vertigo in 42.85 %, and ear fullness in 21.43 %. 3 of 14 patients described obvious inducing factor: tiredness. Five patients (35.71 %) had hypertension histories, three (21.43 %) had diabetes histories, two (14.29 %) had surgery histories, one (7.14 %) was with depression history, one (7.14 %) was with coronary heart disease history. 30 % (3/10) patients were with atherosclerotic plaque in carotid artery. 4 (28.57 %) patients were with high blood sugar. 8 patients (57.14 %) were with high blood lipids. Thyroid function tests were positive in 27.27 % (3/11) patients. No abnormality was found in antinuclear antibodies titer. The percentage of profound and severe hearing loss were 71.43 and 78.57 % in the recently affected ear and contralateral ear separately. The PTAs of the recently affected ear were 77.14 ± 27.12

    The great majority of hearing disorders generates from pathologies in the inner ear, mainly the outer hair cells, as mentioned in the first part of this review. Very often, however, hearing loss appears suddenly and even without external causes like noise exposure. This sudden hearing loss is mostly unilateral, recovers very often spontaneously and should be treated, if persisting. Only in this acute stage there are therapeutic options available. If the inner ear hearing loss is chronic there is no curative therapy, an effective management of the hearing disorder is only possible through rehabilitation. This is due to the fact, that hair cells of all mammals, incl. humans, have no regenerative capacity and neither pharmaceutic agents nor other means can induce regeneration and recovery of hair cells. Even a gen-therapy is not available yet. In the second part of this review the main focus lies in sudden hearing loss and general therapeutic options for inner ear hearing loss.

    Sudden sensorineural hearing loss (SSNHL) is commonly encountered in audiologic and otolaryngologic practice. SSNHL is most commonly defined as sensorineural hearing loss of 30 dB or greater over at least three contiguous audiometric frequencies occurring within a 72-hr period. Although the differential for SSNHL is vast, for the majority of patients an etiologic factor is not identified. Treatment for SSNHL of known etiology is directed toward that agent, with poor hearing outcomes characteristic for discoverable etiologies that cause inner ear hair cell loss. Steroid therapy is the current mainstay of treatment of idiopathic SSNHL in the United States. The prognosis for hearing recovery for idiopathic SSNHL is dependent on a number of factors including the severity of hearing loss, age, presence of vertigo, and shape of the audiogram.

    Previous studies have suggested that risk factors for ischaemic vascular disease, such as cigarette smoking, hypertension and hyperlipidaemia, can also be considered risk factors for the development of idiopathic sudden sensorineural hearing loss (ISSNHL). In this study, we have evaluated the hypothesis that these factors can influence hearing threshold recovery in patients affected by ISSNHL. A total of 141 subjects who suffered an episode of ISSNHL were included. All subjects were assessed with tonal audiometry, auditory brainstem responses and MRI to exclude retrocochlear pathology. Hearing tests were conducted at ISSNHL onset (t = 0) and after 30 days. Patients were divided into three classes according to the presence/absence of one or more cardiovascular risk factors including: history of smoking, total serum cholesterol/triglycerides, history of hypertension and diabetes mellitus. Values of hearing threshold recovery were estimated and comparisons were conducted across the three risk factor classes. 75% of patients affected by ISSNHL showed a threshold recovery. However, the threshold recovery was found to be class-independent (average recovery value of 18 dB HL per classes) and also independent of age and gender. Even if cardiovascular risk factors have been found to be involved in the pathogenesis of ISSNHL, the present study suggests that these factors do not have any significant influence on the threshold recovery in ISSNHL.

    Full Text Available Background/Aim. Idiopathic sudden sensorineural hearing loss (ISSHL is one of the most controversial issues in otology. The aim of this study was to determine whether a delay in treatment has any influence on hearing recovery in ISSHL. Method. This study was designed as a retrospective evaluation of an electronic patient data base of the University Hospital Zürich from January 1995 to August 2006. Five hundred and forty one patients with a sudden hearing loss were identified. The standard treatment was carbogen inhalation (95% O2 and 5% CO2 eight times per day in the duration of 30 minutes and prednisone orally (100 mg in one morning dose for 7 days. Factor that was analyzed included the interval between the onset of symptoms and the beginning of the treatment. The initial hearing loss was described using the pure tone average (PTA in dB hearing level at 4 frequencies (0.5, 1, 2 and 4 kHz. Hearing gain was expressed either as absolute hearing gain (dB values from initial PTA minus dB values from final PTA or as relative hearing gain (absolute hearing gain divided by initial PTA minus baseline PTA × 100. Significant recovery of hearing was defined as the final PTA ≤ 30 dB (or same as PTA of the opposite ear. Results. An absolute hearing gain between the initial audiogram and the final audiogram was 15.1 dB. The mean relative hearing gain was 47%. Three hundred one (57% patients had a significant recovery of hearing, and 228 (43% had not. If the patients received treatment in the first 24 hours after onset of symptoms, then the rate of significant recovery was 56%, and no significant difference existed between this group and the patients who received the therapy after 24 hours, but within seven days (χ2 = 0.007, DF = 1, p > 0.01. Conclusion. These results suggest that it is not critical to begin the treatment of ISSHL immediately as an emergency, but within seven days.

    Melo, Antonio Antunes

    2011-07-01

    Full Text Available Introduction: At the differentiated diagnosis of asymmetrical sensorineural hearing losses, vascular disorders are present, one of which is megadolicho basilar artery. This disease is generally asymptomatic, and when symptoms are found, they can be caused by a compression or ischemia. Clinically, sensorineural hearing loss, tinnitus, headache, facial hypoesthesia, trigeminal neuralgia, vertigo, diplopia and facial palsy, among others, are likely to occur. The image examination of choice for its diagnosis is nuclear magnetic resonance. The megadolicho basilar artery therapy can be surgical or conservative, according to the associated findings. A multidisciplinary approach, including a neurologist, neurosurgeon and an otorhinolaryngologist is recommended for a proper administration of the case. Objective: Report the case of a patient with asymmetrical sensorineural hearing loss, diagnosed of megadolicho basilar artery. Case report: JBS, 57-year-old white male with a history of asymmetrical sensorineural hearing loss and bilateral whistle-like tinnitus for several years. The otorhinolaryngologic evaluation, including otoscopy, anterior rhinoscopy and oral pharynx, was normal. Final Comments: The treatment consisted in following up with the patient, controlling the tinnitus by drugs and using an individual sound amplification apparatus on the left ear.

    Idiopathic sudden sensorineural hearing loss (ISSHL) is the sudden loss of unilateral hearing of unknown etiology. The standard treatment consist of a high dose oral steroid taper. This article serves to review the current literature on intratympanic steroid injections for ISSHL. Current literature suggested intratympanic steroids are equivalent to oral steroid therapy, primary combined therapy is superior to either alone and intratympanic steroids should be offered for salvage therapy in ISSHL.

    2005-08-01

    The purpose of this study was to determine whether the perceived sensory dissonance of pairs of pure tones (PT dyads) or pairs of harmonic complex tones (HC dyads) is altered due to sensorineural hearing loss. Four normal-hearing (NH) and four hearing-impaired (HI) listeners judged the sensory dissonance of PT dyads geometrically centered at 500 and 2000 Hz, and of HC dyads with fundamental frequencies geometrically centered at 500 Hz. The frequency separation of the members of the dyads varied from 0 Hz to just over an octave. In addition, frequency selectivity was assessed at 500 and 2000 Hz for each listener. Maximum dissonance was perceived at frequency separations smaller than the auditory filter bandwidth for both groups of listners, but maximum dissonance for HI listeners occurred at a greater proportion of their bandwidths at 500 Hz than at 2000 Hz. Further, their auditory filter bandwidths at 500 Hz were significantly wider than those of the NH listeners. For both the PT and HC dyads, curves displaying dissonance as a function of frequency separation were more compressed for the HI listeners, possibly reflecting less contrast between their perceptions of consonance and dissonance compared with the NH listeners.

    Full Text Available ABSTRACT INTRODUCTION: The establishment of an individualized prognostic evaluation in patients with a diagnosis of idiopathic sudden sensorineural hearing loss (ISSHL remains a difficult and imprecise task, due mostly to the variety of etiologies. Determining which variables have prognostic value in the initial assessment of the patient would be extremely useful in clinical practice. OBJECTIVE: To establish which variables identifiable at the onset of idiopathic sudden sensorineural hearing loss have prognostic value in the final hearing recovery. METHODS: Prospective, longitudinal cohort study. Patients with ISSHL followed by the Department of Otology-Neurotology of a quaternary hospital were included. The following variables were evaluated and correlated with final hearing recovery: age, gender, vertigo, tinnitus, initial degree of hearing loss, contralateral ear hearing, and elapsed time to treatment. RESULTS: 127 patients with ISSHL were evaluated. Rates of absolute and relative recovery were 23.6 dB and 37.2% respectively. Complete hearing improvement was observed in 15.7% patients; 27.6% demonstrated significant improvement and improvement was noted in 57.5%. CONCLUSION: During the onset of ISSHL, the following variables were correlated with a worse prognosis: dizziness, profound hearing loss, impaired hearing in the contralateral ear, and delay to start treatment. Tinnitus at the onset of ISSHL correlated with a better prognosis.

The aim of this study is the investigation of the effectiveness of intratympanic steroids therapy (IST) in patients with idiopathic sudden sensorineural hearing loss (ISSHL) who had not responded to intravenous treatment, evaluating the overall hearing recovery and comparing the results with different variables. Materials and Methods. Our study consisted of 55 patients with refractory ISSHL who, at the end of 10 days of therapy with intravenous steroids, had puretone 4-frequency average (PTA) of worse than 30 dB. The patients received 0.5 mL of methylprednisolone by direct intratympanic injection. The procedure was carried out up to 7 times within a 20-days period. Statistical analysis was carried out. Results. Overall 29 patients (52.7%) showed improvement in PTA, 24 (43.8%) had no change in hearing, and 2 (3.5%) worsened. There was a significant statistical correlation between hearing recovery and time to onset of symptoms, severity of hearing loss and frequency of hearing loss. Conclusions. IST is an effective and safe therapy in sudden sensorineural hearing loss cases that are refractory to standard treatment. The earlier IST, the hearing losses less than 90 dB and the involvement of the low frequencies seem to influence positively the hearing recovery.

  11. Ethics of Placebo Control in Trials for Idiopathic Sudden Sensorineural Hearing Loss.

    2016-07-01

    Idiopathic sudden sensorineural hearing loss (ISSHL) involves sudden loss of hearing from cochlear or retrocochlear origin of unknown cause. Systemic corticosteroids may be considered in the management of ISSNHL. However, an updated Cochrane systematic review concludes that "the value of steroids in the treatment of idiopathic sudden sensorineural hearing loss remains unclear since the evidence obtained from randomized controlled trials is contradictory in outcome." Therefore, a new clinical trial that addresses this question is mandatory. A first step in its design is to determine if placebo control would be ethically acceptable. We conclude that there is equipoise (uncertainty) about the use of corticosteroids for ISSHL. A new trial is justified-but with the inclusion of interim analyses to detect early imbalances on efficacy or safety and with the ability to stop the trial if needed.

    Full Text Available Etiologies of sudden sensorineural hearing loss (SSNHL include factors such as viral infections, embolism, aneurysm and vascular events. A 63-year-old male patient with a history of hypertension and aortic aneurysm surgery referred to our clinic with complaints of sensorineural hearing loss. The patient fully recovered after medical treatment. He had another SSNHL attack three months later; the examinations revealed that the recurrence of the patient%u2019s aortic aneurysms, which suggested that the etiology might be the microembolism associated with aneurysm in that case. We did not consider hyperbaric oxygen treatment (HBOT an option because it posed a relative risk for the patient. Additionally, as the patient underwent an operation primarily for aneurysm, the SSNHL treatment was interrupted, which resulted in permanent hearing loss. In conclusion, aortic aneurysm is a serious disease that may result in SSNHL, and might affect therapeutic options for this disease.

    Conclusions: CSSNHL commonly occurs unilaterally and results in severe hearing loss. Initial severe hearing loss and bilateral hearing loss are negative prognostic factors for hearing recovery, while positive prognostic factors include tinnitus, gender, the ascending type audiogram, early treatment, identifiable ABR waves, and DPOAEs. Age, vertigo, and ear fullness are not correlated with the recovery. Some serologic indicators, including the level of WBC, platelet, homocysteine, ALP, positive CMV IgG antibody, fibrinogen, and some immunologic indicators, are closely related to CSSNHL.

To review our experience with intratympanic steroids (ITSs for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL, emphasizing the ideal time to perform follow-up audiograms. Methods. Retrospective case review of patients diagnosed with ISSNHL treated with intratympanic methylprednisolone. Injections were repeated weekly with a total of 3 injections. Improvement was defined as an improved pure-tone average ≥20 dB or speech-discrimination score ≥20%. Results. Forty patients met the inclusion criteria with a recovery rate of 45% (18/40. A significantly increased response rate was found in patients having an audiogram >5 weeks after the first dose of ITS (9/13 over those tested ≤5 weeks after the first dose of ITS (9/27 (=0.03. Conclusions. Recovery from ISSNHL after ITS injections occurs more frequently >5 weeks after initiating ITS. This may be due to the natural history of sudden hearing loss or the prolonged effect of steroid in the inner ear.

    Leptomeningeal carcinomatosis is a rare condition characterized by diffuse infiltration of the meninges after the metastasis of the solid tumors. Bilateral sudden hearing loss is a rare initial symptom. In this article, we report a 44-year-old male patient with bilateral sudden hearing loss and dizziness. Magnetic resonance imaging showed involvement of the bilateral vestibulocochlear nerves. Malignant cells were detected in cerebrospinal fluid cytology. To the best of our knowledge, leptomeningeal carcinomatosis due to duodenum adenocarcinoma has not been reported before in the English literature. Leptomeningeal carcinomatosis should be kept in mind in patients who have bilateral sudden sensorineural hearing loss.

    We report on 7 patients (6 M, 1 F) with Coffin-Lowry syndrome who have a sensorineural hearing deficit in addition to developmental delay and characteristic facial changes. One of the patients also had a history of premature exfoliation of primary teeth. These are previously unappreciated clinical signs that may aid in the early diagnosis of Coffin-Lowry syndrome. Early diagnosis and recognition of a hearing deficit in the patient can lead to the use of hearing aids to help the patient achieve his or her full potential. These "new" clinical manifestations expand the phenotype of Coffin-Lowry syndrome and constitute an additional indication of pleiotropy.

    Introduction Sensorineural hearing loss affects a high percentage of the population. Ototoxicity is a serious and pervasive problem in patients treated with cisplatin. Strategies to ameliorate ototoxicity without compromising on antitumor activity of treatments are urgently needed. Similar problems occur with aminoglycoside antibiotic therapy for infections. Noise-induced hearing loss affects a large number of people. The use of ear protection is not always possible or effective. The prevention of hearing loss with drug therapy would have a huge impact in reducing the number of persons with hearing loss from these major causes. Areas covered This review discusses significant research findings dealing with the use of protective agents against hearing loss caused by cisplatin, aminoglycoside antibiotics and noise trauma. The efficacy in animal studies and the application of these protective agents in clinical trials that are ongoing are presented. Expert opinion The reader will gain new insights into current and projected future strategies to prevent sensorineural hearing loss from cisplatin chemotherapy, aminoglycoside antibiotic therapy and noise exposure. The future appears to offer numerous agents to prevent hearing loss caused by cisplatin, aminoglycoside antibiotics and noise. Novel delivery systems will provide ways to guide these protective agents to the desired target areas in the inner ear and will circumvent problems with therapeutic interference of anti-tumor and antibiotics agents and will minimize undesired side effects.

However, little is known about the prevalence of these mutations in sporadic patients with nonsyndromic sensorineural hearing loss. OBJECTIVE: The purpose of our study was to investigate the incidence of these mitochondrial DNA mutations in such population. METHODS: A total of 178 sporadic patients with nonsyndromic sensorineural hearing loss were enrolled in this study. Genomic DNA was extracted from the peripheral blood sample. We employed the SNaPshot(r sequencing method to detect five mitochondrial DNA mutations, including A1555G and A827G in 12S rRNA gene and A7445G, 7472insC, and T7511C in tRNASerUCN gene. Meanwhile, we used polymerase chain reaction and sequenced the products to screen GJB2 gene mutations in patients carrying mitochondrial DNA mutations. RESULTS: We failed to detect the presence of A1555G mutation in 12S rRNA gene, and of A7445G, 7472insC, T7511C mutations in tRNASerUCN gene in our population. However, we found that 6 patients (3.37% were carriers of a homozygous A827G mutation and one of them also carried homozygous GJB2 235delC mutation. CONCLUSION: Our findings in the present study indicate that even in sporadic patients with nonsyndromic sensorineural hearing loss, mitochondrial DNA mutations might also contribute to the clinical phenotype.

    X-linked deafness is a rare cause of hereditary hearing impairment. We have identified a family with X-linked dominant sensorineural hearing impairment, characterized by incomplete penetrance and variable expressivity in carrier females, that is linked to the Xp21.2, which contains the Duchenne muscular dystrophy (DMD) locus. The auditory impairment in affected males was congenital, bilateral, profound, sensorineural, affecting all frequencies, and without evidence of radiographic abnormality of the temporal bone. Adult carrier females manifested bilateral, mild-to-moderate high-frequency sensorineural hearing impairment of delayed onset during adulthood. Eighteen commercially available polymorphic markers from the X chromosome, generating a 10-15-cM map, were initially used for identification of a candidate region. DXS997, located within the DMD gene, generated a two-point LOD score of 2.91 at {theta} = 0, with every carrier mother heterozygous at this locus. Recombination events at DXS992 (located within the DMD locus, 3{prime} to exon 50 of the dystrophin gene) and at DXS1068 (5{prime} to the brain promoter of the dystrophin gene) were observed. No recombination events were noted with the following markers within the DMD locus: 5{prime}DYS II, intron 44, DXS997, and intron 50. There was no clinical evidence of Duchenne or Becker muscular dystrophy in any family member. It is likely that this family represents a new locus on the X chromosome, which when mutated results in nonsyndromic sensorineural hearing loss and is distinct from the heterogeneous group of X-linked hearing losses that have been previously described. 57 refs., 6 figs., 1 tab.

    Idiopathic sudden sensorineural hearing loss (ISSHL) is a common otologic emergency whose cause is still unclear. The importance of blood lipids in the pathogenesis of ISSHL is widely reported in literature. In fact elevated levels of low density lipoprotein cholesterol (LDL), total cholesterol (TC) and apolipoprotein B (Apo-B) have been proposed as risk factors for this pathology. No correlation has been described between serum lipid parameters and the prognosis of ISSHL. Aim of the present ...

    We studied the effect of intratympanic steroid administration with different intervals on hearing outcomes in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). The subjects were 197 consecutive patients (197 ears) with ISSNHL (hearing level ≥40 dB, interval between onset and treatment ≤30 days). They received systemic administration of prednisolone (100 mg followed by tapered doses) combined with intratympanic injection of dexamethasone (4 mg/ml). Intratympanic injection was performed once a week for 4 weeks in 105 patients (long-interval group), or 4 times in 1 week in 92 patients (short-interval group). The hearing outcomes were evaluated at two points of time: 1 week from the start of treatment, and 1-2 months after the completion of treatment when the hearing level reached a plateau. There was no significant difference in the cure rate, marked-recovery rate, recovery rate, hearing gain, hearing level, or percent hearing improvement between the long- and short-interval groups at either point of time. Multiple regression analysis also showed that the final hearing level did not depend on the interval of intratympanic steroid injection. These results indicate that the hearing outcome of ISSNHL does not improve even if the interval of intratympanic injection is shortened. This implies that a lower total number of intratympanic steroid injections may be as effective as the present protocol.

    This case report highlights an unusual case of sudden sensorineural hearing loss related to superficial siderosis (SS). Our patient had a craniotomy for medulloblastoma 23 years earlier, and this may represent a delayed complication related to this procedure. Magnetic resonance imaging (MRI) remains the key diagnostic investigation to illustrate the imaging features of superficial siderosis and exclude other pathologies. Increased awareness of progressive and sudden hearing complications caused by SS is important in the otolaryngologic community to expedite management and better counsel patients during the consent process.

    The new revised version (expires 2012) for sudden, unilateral, sensorineural hearing loss stresses the urgence but not the emergency of diagnostics and therapy in this inner ear disfunction with still increasing incidence. Minimum diagnostics should comprise ENT examination with earmicroscopy, pure tone and tuning fork hearing tests, tympano- and vestibulometry. Classification by frequency loss seems of interest in regard to different underlying pathology, which is still obscure. Therefore from experience glucocorticoids and rheological therapy are recommended in the light of some favoring recent studies. The intratympanic appliCation of glucokorticoids is considered as spare therapy.

    A narrow internal auditory canal (IAC) with duplication is a rare anomaly of the temporal bone. It is associated with congenital sensorineural hearing loss. Aplasia or hypoplasia of the vestibulocochlear nerve may cause the hearing loss. We present an unusual case of an isolated narrow IAC with duplication that was detected by a CT scan. In this case, the IAC was divided by a bony septum into an empty stenotic inferoposterior portion and a large anterosuperior portion containing the facial nerve that was clearly delineated on MRI.

    We describe an imported case of Lassa fever with both encephalopathy and bilateral sensorineural hearing deficit. Absence of fever during hospitalization, initially nonspecific symptoms, and onset of hearing deficit in a late stage of disease probably contributed to delayed diagnosis (14 days after admittance to hospital). The pathogenesis of neurological manifestations of Lassa fever is poorly understood and no specific treatment was given. A total of 118 personnel had close contact with the patient, but no secondary cases occurred. This case highlights the importance of considering Lassa fever as a differential diagnosis in patients with recent travel to endemic areas.

    Full Text Available Abstract Background Sudden sensorineural hearing loss is routinely encountered by the otologist. The etiology is varied and often identifiable. One of the relatively less frequent causes is surgery. Apart from being an established entity with otological surgeries, sensorineural hearing loss has also been known to occur after non-otological procedures under general anesthesia. Commonest amongst these procedures is cardiopulmonary bypass, an association that has long been recognized. However, despite the proposition of diverse hypotheses in the past, the pathophysiology remains unclear. Methods The study is a prospective matched cohort study that will be carried out in Aga Khan University Hospital, Karachi, Pakistan. Participants among exposed would include all those patients who would be undergoing coronary artery bypass surgery in the hospital who fall under the criteria for inclusion. Unexposed group would comprise of patients undergoing a non-bypass procedure of similar duration under the same type of anesthesia who meet the selection criteria. Both these groups will undergo audiometric testing at our hospital on three different occasions during the course of this study. Initially before the procedure to test the baseline hearing capacity; then one week after the procedure to assess any changes in hearing ability following the surgery; and finally a third audiogram at six weeks follow-up to assess further changes in any hearing deficits noted during the second phase of testing. Certain variables including the subjects' demographics and those concerning the procedure itself will be noted and used later for risk factors analysis. A detailed past medical and surgical history will also be obtained. Data analysis would include calculation of relative risk and significance of the results, by running the chi-square test. Other statistical tests like Fisher exact test may then be employed to facilitate data interpretation. Continuous scale may then be

    This case highlights the diagnostic challenges in patients presenting with bilateral sudden sensorinueral hearing loss (SNHL). The aetiology of bilateral sudden SNHL may span several medical disciplines. Therefore, clinicians should be mindful of such presentations, and consider aetiologies beyond otological and neurological causes. We present a case of a previously healthy 51-year-old woman who presented with coryzal symptoms and sudden audiovestibular failure. Examination revealed fever, tachycardia, bilateral profound hearing loss and nystagmus. Following investigations, an initial working diagnosis of vasculitis was made. Later, blood cultures revealed methicillin-sensitive Staphylococcus aureus (MSSA) and a transoesophageal echocardiogram confirmed endocarditis. The patient made a good recovery, but the hearing loss was permanent and managed with a cochlear implant.

    Sudden sensorineural hearing loss (SSNHL) can cause significant morbidity. Treatment with steroids can improve outcome. Delay in initiation of treatment reduces the chance to regain hearing. For this reason SSNHL is considered an emergency. Diagnosis is based on history, physical examination and a standard audiogram, the latter requiring specialized equipment and personnel. Standard audiogram may not be available at the time and place of patient presentation. A smartphone or tablet computer-based hearing test may aid in the decision to prescribe steroids in this setting. In this study the uHear™ hearing test application was utilized. The output of this ear-level air conduction hearing test is reported in hearing grades for 6 frequencies ranging from 250 to 6000 Hz. A total of 32 patients with unilateral SSNHL proven by a standard audiogram were tested. The results of standard and iPod hearing tests were compared. Based on the accepted criterion of SSNHL (at least 30 dB loss - or 2 hearing grades - in 3 consecutive frequencies) the test had a sensitivity of 0.76 and specificity of 0.91. Using a less stringent criterion of a loss of 2 hearing grades over at least 2 frequencies the sensitivity was 0.96 and specificity 0.86. The correlation coefficient for the comparison of the average hearing grade across the 6 measured frequencies of the study and standard audiogram was 0.83. uHear more accurately reflected hearing thresholds at mid and high tones. Similarly to previously published data, low frequency thresholds could be artificially elevated. In conclusion, uHear can be useful in the initial evaluation of patients with single-sided SSNHL by providing important information guiding the decision to initiate treatment before a standard audiogram is available.

    Inner ear malformations are frequently found in patients with congenital hearing loss. It has been reported that normal hearing is rare in patients with severe inner ear vestibular malformations. A 9-year-old boy had had complained of recurrent dizziness and disequilibrium for 2 months. Clinical and neuro-otological examinations showed peripheral involvement of the vestibular system, while audiological investigation was normal. High-resolution magnetic resonance imaging, with three-dimensional reconstruction, showed dysplasia of the bilateral lateral semicircular canals (LSCCs). Isolated vestibular malformation might not be as rare as previously thought, and should be examined by imaging of the temporal bone.

    Full Text Available Hearing impairment is common in patients with mitochondrial disorders, affecting over half of all cases at some time in the course of the disease. In some patients, deafness is only part of a multisystem disorder. By contrast, there are also a number of “pure” mitochondrial deafness disorders, the most common probably being maternally inherited. We retrospectively analyzed the last 60 genetically confirmed mitochondrial disorders diagnosed in our Department: 28 had bilateral sensorineural hearing loss, whereas 32 didn't present ear's abnormalities, without difference about sex and age of onset between each single group of diseases. We reported also a case of MELAS patient with sensorineural hearing loss, in which cochlear implantation greatly contributed to the patient's quality of life. Our study suggests that sensorineural hearing loss is an important feature in mitochondrial disorders and indicated that cochlear implantation can be recommended for patients with MELAS syndrome and others mitochondrial disorders.

    Full Text Available Sudden sensorineural hearing loss (SSNHL is a common otological disorder characterized by a hearing loss greater than 30 dB over three consecutive frequencies, in less than 72 hours. It has been established that platelet parameters, such as mean platelet volume, are associated with ischemic heart events, whose clinical manifestations are similar to those of SSNHL. Hence, we aimed to determine if the platelet count, mean platelet volume and platelet distribution width are related to the occurrence and severity of sudden sensorineural hearing loss. A case-control prospective study was conducted in a teaching hospital in Iran. One hundred-eight patients with SSNHL and an equal number of healthy, age- and sex-matched controls were enrolled in the study. Peripheral venous blood samples were collected from the subjects, and the platelet count, mean platelet volume and platelet distribution width were measured with an automated blood cell counter. Analysis of the audiometry and hematological test results using SPSS22 software showed no statistical correlation between the platelet parameters and the occurrence of SSNHL, but correlation coefficients showed a significant correlation between PDW and hearing loss severity in patients group. However, further investigation is required to unequivocally establish the absence of correlation between the platelet parameters and occurrence of SSNHL.

Patients were randomized to the intervention group (combined intratympanic and systemic steroid therapy or the control group (systemic steroid therapy alone. All patients received oral treatment with systemic prednisolone (1 mg/kg/day for 10 days, acyclovir (2 g/day for 10 days, divided into four doses, triamterene H (daily, and omeprazole (daily, during steroid treatment, and were advised to follow a low salt diet. The intervention group also received intratympanic dexamethasone injections (0.4 ml of 4 mg/ml dexamethasone two times a week for two consecutive weeks (four injections in total. A significant hearing improvement was defined as at least a 15-db decrease in pure tone average (PTA.  Results: Among all participants, 44 patients (57.14% showed significant improvement in hearing evaluation. More patients showed hearing improvement in the intervention group than in the control group (27 patients (75% versus 17 patients (41.4%, respectively; P = 0.001.  Conclusion:  The combination of intratympanic dexamethasone and systemic prednisolone is more effective than systemic prednisolone alone in the treatment of poor-prognosis SSNHL.

    Hearing loss is one of the most widespread sensory disorders. The incidence of deafness in general population is 1:1000 newborns. About one half of the cases of the congenital sensorineural hearing loss (SNHL) is inherited. Recessive mutations in the gap junction beta 2 (GJB2) gene are the most common genetic causes of the nonsyndromic SNHL. The GJB2 encodes a protein connexin 26 which forms a subunit of gap junction essential for the correct function of the inner ear. The syndromic SNHL is associated with a wide range of other symptoms, which encompass also dysfunctions of endocrine organs. The Pendred syndrome associated with the hearing impairment is characterized by a prelingual, bilateral sever to profound SNHL, goiter, and iodine organification defect. It is an autosomal recessive disorder, which develops due to mutations in pendrin, an anion channel encoded by SLC26A4 gene. Another important type of syndromic hearing loss is the Maternally Inherited Diabetes and Deafness syndrome, which is caused by several mitochondrial DNA mutations. These mutations are clinically manifested by a hearing impairment with development of the diabetes in the adult age. Hearing impairment occurs during puberty when sensation of high frequency tones is affected following with further progress to profound bilateral sensorineural hearing impairment in the whole frequency range. This review deals with the molecular mechanisms of common genetic causes of the hereditary SNHL along with the selected endocrinopathies emphasizing that the DNA analyses along with the functional studies significantly contribute to the early SNHL diagnosis followed by personalized therapy and genetic counseling.

    Full Text Available Whereas the language development of children with sensorineural hearing impairment (SNHI has repeatedly been shown to differ from that of peers with normal hearing (NH, few studies have used an experimental approach to investigate the consequences on everyday communicative interaction. This mini review gives an overview of a range of studies on children with SNHI and NH exploring intra- and inter-individual cognitive and linguistic systems during communication.Over the last decade, our research group has studied the conversational strategies of Swedish speaking children and adolescents with SNHI and NH using referential communication, an experimental analogue to problem-solving in the classroom. We have established verbal and nonverbal control and validation mechanisms, related to working memory capacity (WMC and phonological short term memory (PSTM. We present main findings and future directions relevant for the field of cognitive hearing science and for the clinical and school-based management of children and adolescents with SNHI.

    Physiological studies have shown that noise-induced sensorineural hearing loss (SNHL) enhances the amplitude of envelope coding in auditory-nerve fibers. As pitch coding of unresolved complex tones is assumed to rely on temporal envelope coding mechanisms, this study investigated pitch-discrimination...... performance in listeners with SNHL. Pitch-discrimination thresholds were obtained for 14 normal-hearing (NH) and 10 hearing-impaired (HI) listeners for sine-phase (SP) and random-phase (RP) complex tones. When all harmonics were unresolved, the HI listeners performed, on average, worse than NH listeners...... in the RP condition but similarly to NH listeners in the SP condition. The increase in pitch-discrimination performance for the SP relative to the RP condition (F0DL ratio) was significantly larger in the HI as compared with the NH listeners.

    A total of 524 industrial workers were studied. They consisted of 442 noise exposed and 82 non-noise exposed workers. The purpose was to compare the prevalence of sensori-neural hearing loss among the noise exposed and the non-noise exposed workers, to study their knowledge on the hazard of noise to hearing and the workers' attitude towards the hearing protection devices. The prevalence of sensori-neural hearing loss was significantly higher among the noise exposed workers, i.e., 83% versus 31.7% (p workers, only 5.1% were wearing them regularly. The possibility of developing hearing loss due to exposure to excessive noise was only known by 35.5% of the noise exposed workers. This awareness was found to have a positive correlation with the workers' compliance to the hearing protection devices. Our findings highlight the need for workers to be educated on the hazards of excessive noise exposure to hearing.

A 37-year-old woman had combined dysplasia of the posterior and lateral semicircular canals (PSCC, LSCC) with normal cochlear development and normal hearing in both ears. She had complained of dizziness for 8 months. High resolution computed tomography (CT) showed hypogenesis of the bony labyrinth in both ears. Bilateral PSCC and LSCC dysplasia and dilatation of the vestibule were detected. Magnetic resonant imaging (MRI) revealed that the deformity of the PSCC was more severe than the LSCC. Although the caloric test of the left ear elicited no nystagmus and there was reduced response in the right ear, the horizontal vestibulo-occular reflex (VOR) was present. Her dizzy sensation disappeared within 3 months without special treatment. The dizziness attack might have been caused by a temporary breakdown of her peripheral vestibular system.

    Recent physiological studies in animals showed that noise-induced sensorineural hearing loss (SNHL) increased the amplitude of envelope coding in single auditory-nerve fibers. The present study investigated whether SNHL in human listeners was associated with enhanced temporal envelope coding...... of cochlear compression. Overall, these findings suggest that some HI listeners may benefit from an enhancement of temporal envelope coding in pitch discrimination of unresolved complex tones, and that this enhancement may be also ascribed to a reduction of cochlear compression following SNHL. © 2015......

    Full Text Available A 58 years old man with a no history of hearing loss was admitted with comminuted fracture tibia and fibula (right, sustained in a road traffic accident [Fig. 1]. He had no known comorbidity. The pre-operative history and physical examination, blood test investigations, chest radiograph [Fig. 2] and ECG were unremarkable. He was taken up for open reduction and pinning of fractured segments [Fig. 3]. The orthopedic surgery itself was uneventful with the patient being under general anesthesia for a total of one hour. Induction of anesthesia was uncomplicated, and blood loss was minimal. The blood pressure and pulse remained stable, with minimum diastolic and systolic pressure during surgery being 70 mmHg and 130 mmHg respectively. Oxygen saturation remained over 95 percent.

    We report a very rare case of hearing improvement after removal of the intracranial part of a jugular foramen schwannoma (JFS) presenting with chronic and severe progressive sensorineural hearing loss (SNHL). The patient presented with progressive hearing impairment in his right ear, lasting 2 years. The patient's pure tone audiogram revealed severe SNHL. His speech discrimination score (SDS) was 0%. Auditory-evoked brain responses (ABRs) comprised only I waves following 30-100dB stimulation, although distortion-product otoacoustic emissions (DPOAEs) had good responses. These test results indicated that his hearing impairment was retrocochlear SNHL. Magnetic resonance imaging revealed within the right jugular foramen a large intracranial-extracranial tumor that compressed the brainstem. The intracranial part of the tumor was resected through retrosigmoidal craniotomy, and the tumor was pathologically diagnosed as a schwannoma. Several months after the operation, the patient's auditory thresholds improved to a level consistent with mild SNHL, ABR V waves emerged following 60-90dB stimulation, and SDS improved significantly to 95%. This case demonstrates that hearing improvement can be achieved after surgery for JFS presenting with severe and chronic progressive SNHL, and that good DPOAE responses and the presence of ABR I waves may be predictors of postoperative hearing recovery in JFS.

    Full Text Available INTRODUCTION Cochlear damage secondary to exposure to acoustic trauma is the consequence of the acoustic energy effects on the hearing cells in Korti's organ. OBJECTIVE The objective was to assess the correlation between the degree of sensorineural hearing loss and the type of audiogram registered in acoustic trauma exposed patients. METHOD We analyzed 262 audiograms of patients exposed to acoustic trauma in correlation to 146 audiograms of patients with cochlear damage and hearing loss not related to acoustic trauma. "A" group consisted of acoustic trauma cases, while "B" group incorporated cases with hearing loss secondary to cochlear ischaemia or degeneration. All audiograms were subdivided with regard to the mean hearing loss into three groups: mild (21-40 dB HL, moderate (41-60 dB HL and severe (over 60 dB HL hearing loss. Based on audiogram configuration five types of audiogram were defined: type 1 flat; type 2 hearing threshold slope at 2 kHz, type 3 hearing threshold slope at 4 kHz; type 4 hearing threshold notch at 2 kHz; type 5 notch at 4 kHz. RESULTS Mild hearing loss was recorded in 163 (62.2% ears in the acoustic trauma group, while in 78 (29.8% ears we established moderate hearing loss with the maximum threshold shift at frequencies ranging from 4 kHz to 8 kHz. The least frequent was profound hearing loss, obtained in 21 (8% audiograms in the acoustic trauma group. Characteristic audiogram configurations in the acoustic trauma patient group were: type 1 (N=66; 25.2%, type 2 (N=71; 27.1%, and type 3 (N=68; 25.9%. Audiogram configurations were significanly different in the acoustic trauma group in comparison to the cochlear ischaemia group of patients (p=0.0005. CONCLUSION Cochlear damage concomitant to acoustic trauma could be assessed by the audiogram configuration. Preserved hearing acuity at low and mild frequency range indicates the limited damage to the hearing cells in Korti's organ in the apical cochlear turn.

    Sudden sensorineural hearing loss (SSNHL) is being described with increasing incidence among patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). There are no widely accepted guidelines in the medical literature for the appropriate management of this medical emergency. Administration of systemic steroids remains the mainstay of the management of SSNHL in conjunction with the supportive treatment, in this vulnerable group of patients, as well. However, encouraged by the evolving evidence on the efficacy of the intratympanic steroid injections (ITSI) in the treatment of SSNHL among patients without renal disease--we successfully treated SSNHL in an elderly diabetic with sepsis due to bilateral pneumonitis undergoing regular HD treatment with multiple ITSI and antibiotics resulting in complete recovery of hearing function within 3 months of onset of the first symptoms.

    The objective of this study is to use standardized measurements of the inner ear to see whether there are subtle bony malformations in children with congenital sensorineural hearing loss (SNHL) whose temporal bone computed tomography (CT) are grossly normal. The study includes 45 ears with congenital SNHL and grossly normal temporal bone CT scans and 45 ears with normal inner ear structures and normal hearing. Standardized measurements of the inner ear structures were made on axial temporal bone CT scans. Student's t test was performed to compare the measurements of the two groups. There were significant differences in the measurements of the bony island width of the superior semicircular canal, bony island width of the lateral semicircular canal and maximal height of cochlea between two groups (P inner ear on temporal bone CT can identify subtle abnormalities of inner ear in patients with congenital SNHL having grossly normal radiological images.

    With a worldwide incidence estimated at 8-15 per 100,000 population a year, idiopathic sudden sensorineural hearing loss (ISSHL) is a common clinical finding for otologists. There is a shortage of information on the clinical factors capable of predicting hearing recovery and response to therapy. The aim of the present study was to retrospectively investigate the prognostic value of clinical variables in relation to hearing recovery, in a cohort of 117 consecutive patients with ISSHL. Clinical parameters (signs, symptoms, comorbidities and treatments) and audiometric data were analyzed with univariate and multivariate statistical approaches for prognostic purposes to identify any correlation with hearing recovery, also expressed according to the Wilson criteria. Univariate analysis showed that age and hypertension were significantly related to hearing outcome (p = 0.004 and p = 0.015, respectively). Elderly patients and those with hypertension were at higher risk of experiencing no hearing recovery (OR = 3.25 and OR = 2.89, respectively). Age was an independent prognostic factor on multivariate analysis (p = 0.007). Tinnitus as a presenting symptom showed a trend towards an association with hearing recovery (p = 0.07). The treatment regimen, the time elapsing between the onset of symptoms and the start of therapy (p = 0.34), and the duration of the treatment (p = 0.83) were unrelated to recovery on univariate analysis. Among the parameters considered, only age was significantly and independently related to hearing outcome. There is a need for well-designed, randomized clinical trials to enable an evidence-based protocol to be developed for the treatment of ISSHL.

    Full Text Available Objectives: To investigate possible sensorineural hearing loss created by the use of a cold light source in patients undergoing endoscopic tympanoplasty surgery. Materials and Methods: The medical records of 203 patients, who underwent endoscopic Type 1 tympanoplasty surgery in our ear, nose, and throat clinic between 2012 and 2015, were checked retrospectively. Ninety-one patients were male and 112 were female, and their mean age was 34.4 ± 11.2 years. Results of audiometric measurements performed during the preoperative period and repeated 1 and 3 months postsurgery were compared to each other. Results: The mean duration of the operations was determined to be 52.4 ± 9.1 min. In addition, average preoperative bone-conduction was 11.4 ± 7.4 dB nHL. However, it was 9.57 ± 7.1 dB nHL and 9.51 ± 7.4 dB nHL, respectively, in the 1st and 3rd postoperative months. Levels of postoperative average bone-conduction at the 1st and 3rd month, as well as the thresholds of bone-conduction at 500, 1000, and 2000 Hz, were significantly lower than the preoperative results (P 0.05. Conclusion: Based on our findings, the increased heat generated by the use of a cold light source during an endoscopic tympanoplasty surgery is unlikely to cause the development of sensorineural hearing loss.

    Many congenital dysplasias of the osseous labyrinth have been identified, and the differential diagnosis of these dysplasias is essential for delivering proper patient management. We retrospectively reviewed the computed tomography (CT) and magnetic resonance (MR) imaging findings of 20 children who had congenital sensorineural hearing loss. The children included cases of enlarged vestibular aqueduct and endolymphatic sac (n=8), aplasia of the semicircular canal (n=4), lateral semicircular canal-vestibule dysplasia (n=3), common cavity malformations with a large vestibule (n=1), cochlear hypoplasia (n=1), Mondini's dysplasia with large vestibular aqueduct (n=1), Mondini's dysplasia with a large vestibule (n=1), and small internal auditory canal (n=1). Six cases were unilateral. Nine cases had combined deformities, and nine cased had cochlear implants. CT was performed with a 1.0-mm thickness in the direct coronal and axial sections with using bone algorithms. MR was performed with a temporal 3D T2 FSE 10-mm scan and with routine brain images. We describe here the imaging features for the anomalies of the inner ear in patients suffering from congenital sensorineural hearing loss.

    A randomized placebo-controlled study has demonstrated no effect of prednisolone in customary dosage on idiopathic sudden sensorineural hearing loss (ISSNHL). The aim of the present paper is to analyse a larger patient group by meta-analysis of data from the RCT together with a corresponding material drawn from the Swedish national database for ISSNHL. Data from 192 patients, 18-80 years with ISSNHL, were available. All had an acute hearing loss of at least 30 dB measured as PTA in the three most affected contiguous frequencies. All patients had been enrolled within one week after onset and evaluated by audiograms after 3 months. 45/99 (RCT) and 54/99 (the database) had been treated with prednisolone in tapering doses from 60 mg daily and 42/93 with placebo (RCT) or 51/93 with no treatment (the database). Primary outcome was the mean hearing improvement on day 90 for the different groups. A mean difference of >10 dB improvement was required to demonstrate a treatment effect for prednisolone compared to placebo/no treatment. No significant difference was seen between the prednisolone group and placebo/no treatment (p = 0.06). Total recovery was 38% in prednisolone group, 40% in the placebo and 14% in the no treatment group. Vertigo at the onset of hearing loss and age at onset had an equal negative prognostic value in all groups and signs of inflammation had a positive effect. Prednisolone in customary dosage does not influence recovery after ISSNHL.

    Objective: To investigate the possible factors related to recurrence and prognosis of sudden sensorineural hearing loss(SSNHL). Methods: Four hundred and ninety-five patients with unilateral sudden sensorineural hearing loss between January 2013 to April 2014 were analyzed retrospectively(34 patients lost to follow-up with a dropout rate of 6.87%). Twenty of the 495 patients were diagnosed as recurrent SSNHL and treated again in the same hospital. The data of the patients were summarized to analyze the related factors which might influence the recurrence and prognosis of SSNHL. Results: In the 20 patients with recurrent SSNHL, 19 had the second attack in same ear as the first attack, and the other one had in both ears. There were seven male patients, and thirteen female patients. Patients ranged in age from 24 to 77years, with a median age of 39.5 years. Types of hearing loss: low frequency in eight patients, high frequency in two patients, flat frequency in eight patients, total deafness in two patients, the types of the second attack in 17 patients were same as the first attack, only one patient was changed from total deafness to flat frequency, one case was changed from flat frequency to high frequency, one case changed from flat frequency to total deafness. The intervals between of the first attack time and the second attack time were 1-36 months with the median time of 3.5 months. After systemic oral and (or) transtympanic steroid treatment, recovered in three cases, effective in three cases and 14 cases invalid, the cure rate was 15%, and the total effective rate was 30%. There were statistically significant differences in the recovery rate(χ(2)=8.640, Phearing loss except low frequency type, the treatment effect was invalid. The patients with hearing loss at low frequency had the best outcomes. The total effective rates were significant different between patients younger and old than 34 years old(P0.05).

    2013-01-01

    Full Text Available Sudden sensorineural hearing loss may be present as a symptom in systemic autoimmune diseases or may occur as a primary disorder without another organ involvement (autoimmune inner ear disease. The diagnosis of autoimmune inner ear disease is still predicated on clinical features, and to date specific diagnostic tests are not available. We report a case of bilateral sudden hearing loss, tinnitus, intense rotatory vertigo, and nausea in a female patient in which the clinical manifestations, in addition to raised levels of circulating immune complexes, antithyroglobulin antibodies, and the presence of the HLA A1-B8-DR3 haplotype, allowed us to hypothesize an autoimmune inner ear disease. Cyclosporine-A immunosuppressive treatment in addition to steroids helped in hearing recovery that occurred progressively with normalization of the hearing function after a five-month treatment. Cyclosporine-A could be proposed as a therapeutic option in case of autoimmune inner ear disease allowing the suspension of corticosteroids that, at high dose, expose patients to potentially serious adverse events.

    The auditory function of sixty two Kenyan sickle cell anaemia patients aged seven to thirty years was compared to age-matched fifty five healthy controls with haemoglobin AA. Sensorineural hearing loss of 30 db and above was demonstrated in 25 (40%) of sickle cell anaemia patients and in three (5.5%) control subjects. Both sexes were equally affected. Bilateral lesion registered in 16%. Hearing threshold level was normal in 97% of the sickle cell group. High frequencies were commonly affected with hearing loss of 30-40 db. Two cases with severe unilateral deafness at all frequencies had severe recruitment suggestive of cochlea lesion. There were no cases of acoustic reflex decay in all study patients. The hearing loss was of slow onset. The high risk of deafness in Kenyan sickle cell anaemia patients may be a reflection of the severe course of the disease due to specific Kenyan haematological profile (haplotype 20 with low Hb F level), the level of medical care available and the geographical distribution in the tropics together with other factors.

    The aim of this study was to assess the outcomes of various treatment modalities for profound idiopathic sudden sensorineural hearing loss (ISSNHL) and confirm the prognostic factors. In total, 191 patients were enrolled after a thorough medical chart review of patients diagnosed with unilateral, profound ISSNHL (≥90 dB). Epidemiological profiles, therapeutic regimens, and the results of pure tone audiometry tests were recorded for all patients. Final recovery was assessed according to Siegel's criteria and by comparing the final hearing level of the affected ear with that of the unaffected ear. The mean follow-up duration and the final hearing level were 75 ± 54 days and 77 ± 24 dB, respectively. None of the evaluated prognostic factors were significantly associated with complete recovery (hearing in both ears, the absence of dizziness, the use of lipo-prostaglandin E1 (lipo-PGE1), and the use of plasma volume expanders were independently associated with a final hearing level of up to 45 dB (p hearing, and non-use of lipo-PGE1 increased the possibility of no recovery. Although the efficacy of oral steroid treatment for profound ISSNHL has been questioned, steroid dose reduction was significantly associated with no recovery. Therefore, adequate oral corticosteroid doses should be considered in the absence of contraindications. In addition, the use of lipo-PGE1 and/or a plasma volume expander seems preferable for better recovery, and their use for the management of profound ISSNHL should be considered.

    Idiopathic sudden sensorineural hearing loss (ISSHL) is a common otologic emergency whose cause is still unclear. The importance of blood lipids in the pathogenesis of ISSHL is widely reported in literature. In fact elevated levels of low density lipoprotein cholesterol (LDL), total cholesterol (TC) and apolipoprotein B (Apo-B) have been proposed as risk factors for this pathology. No correlation has been described between serum lipid parameters and the prognosis of ISSHL. Aim of the present study was to identify prognostic factors associated with hearing recovery in a group of patients affected by ISSHL. Ninety-four patients with the diagnosis of ISSHL hospitalized between March 2013 and October 2014 were included in this study. Patients' blood sampling and hearing assessments were carried out. Patients were divided into two groups as "recovered" and "unrecovered", according to their response to the treatment. We found a statistically significant higher level of total cholesterol in the unrecovered group compared to the recovered one (p = 0.03). None of the other routine laboratory parameters have shown a statistically significant difference between the patients successfully treated and patients with poor outcomes. Total cholesterol concentrations may be a prognostic factor for recovery in ISSHL and should be assessed together with routine tests in patients with this condition. The other routine laboratory parameters seem to have no effect on the development and prognosis of this pathology.

    Sudden sensorineural hearing loss is a clinical condition characterized by a sudden onset of unilateral or bilateral hearing loss. In recent years sudden deafness has been frequently described in association with anterior inferior cerebellar artery (AICA) infarction generally presenting along with other brainstem and cerebellar signs such as ataxia, dysmetria and peripheral facial palsy. The authors report a rare clinical case of a 53-year-old man who suddenly developed hearing loss and tinnitus without any brainstem or cerebellar signs. Computed tomography of his brain was normal, and the audiological results localized the lesion causing deafness to the inner ear. Surprisingly, magnetic resonance imaging showed an ischemic infarct in the right AICA territory. This case represents the fifth in the literature to date but it confirms that AICA occlusion can cause sudden deafness even without brainstem or cerebellar signs. Therefore, we recommend submitting the patient for neuroimaging, as an emergency, in order to exclude infarction of the AICA territory. By doing this, it may be possible to limit the extent of the lesion by commencing early therapy.

  14. Immune system of the inner ear as a novel therapeutic target for sensorineural hearing loss

    Full Text Available Sensorineural hearing loss (SNHL is a common clinical condition resulting from dysfunction in one or more parts in the auditory pathway between the inner ear and auditory cortex. Despite the prevalence of SNHL, little is known about its etiopathology, although several mechanisms have been postulated including ischemia, viral infection or reactivation, and microtrauma. Immune-mediated inner ear disease has been introduced and accepted as one SNHL pathophysiology; it responds to immunosuppressive therapy and is one of the few reversible forms of bilateral SNHL. The concept of immune-mediated inner ear disease is straightforward and comprehensible, but criteria for clinical diagnosis and the precise mechanism of hearing loss have not been determined. Moreover, the therapeutic mechanisms of corticosteroids are unclear, leading to several misconceptions by both clinicians and investigators concerning corticosteroid therapy. This review addresses our current understanding of the immune system in the inner ear and its involvement in the pathophysiology in SNHL. Treatment of SNHL, including immune-mediated inner ear disorder, will be discussed with a focus on the immune mechanism and immunocompetent cells as therapeutic targets. Finally, possible interventions modulating the immune system in the inner ear to repair the tissue organization and improve hearing in patients with SNHL will be discussed. Tissue macrophages in the inner ear appear to be a potential target for modulating the immune response in the inner ear in the pathophysiology of SNHL.

    Full Text Available Background: Chronic Suppurative Otitis Media (CSOM is the major cause of hearing impairment, mainly conductive type of hearing loss. The occurrence of sensorineural hearing loss (SNHL in CSOM is controversial and the controversy is more for safe mucosal type. This study aims to assess the association between SNHL and safe mucosal CSOM and its relation to patient's age, sex, duration of disease, active or inactive disease and speech frequencies. Methods: 100 patients with unilateral mucosal type of CSOM with normal contralateral ear were included in the study. The infected ear was taken as study ear and normal ear as control ear in all patients. All patients underwent hearing assessment by pure tone audiometry for both ears. In case of active disease, ear discharge was first cleared and then audiometric assessment done. Results were statistically compared in all patients for both study and control ears using parameters of patient's age, sex, duration of disease, speech frequency and active or inactive disease. Results: There was significant higher number of study ears with CSOM having average bone conduction threshold of all frequencies above 25 decibels which implies SNHL (21% compared to control contralateral ears without infection (5%. There was higher incidence of SNHL at higher speech frequencies. The incidence also increased with age of patient and duration of disease. The incidence was higher in active stage than inactive or quiescent stage. There was no difference among males and females. Conclusion: Safe mucosal CSOM can cause significant SNHL and risk increases with increasing age, duration of disease, higher speech frequencies and presence of active disease.

    Background: During the past years various drugs have been used for sudden sensorineural hearing loss (SSNHL) treatment including steroids that are shown to be beneficial. Directed delivery of high doses of steroids into the inner ear is suggested for its potential and known as intratympanic steroids therapy (IST). Despite the use of dexamethasone and methylprednisolone as the traditional treatments, there are still debates about the optimal dosage, preferred drug, and the route of administration. Materials and Methods: We performed a randomized clinical trial study in which 50 patients suffering from SSNHL and resistant to standard therapy were employed. Each patient took 0.5 ml methylprednisolone (40 mg/mg) along with bicarbonate or dexamethasone (4 mg/mL) through direct intratympanic injection. This method was performed and scheduled once every 2 days for three times only for the dexamethasone receiving group. Hearing test was carried out and the results were analyzed according to a four-frequency (0.5, 1.0, 2.0, 3.0 kHz) pure tone average (PTA) and Siegel's criteria. Results: According to Siegel's criteria, three out of 25 (12%) dexamethasone receiving patients were healed in 1 and 4 (16%), 9 (32%) were respectively recovered in Siegel's criteria 2, 3, and 9 (32%) showed no recovery. In the group receiving methylprednisolone, recovery was found in 6 (24%), 8 (32%), 7 (28%) patients in the Siegel's criteria 1, 2, 3, respectively, and in 4 (16%) patients no recovery was recorded. In methylprednisolone group, hearing was significantly improved compared to the dexamethasone group (P hearing improvement rate was 84% in methylprednisolone receiving patients showing a significantly higher improvement than 64% in the dexamethasone group. Conclusions: Topical intratympanic treatment with methylprednisolone is safe and an effective treatment approach for those SSNHL cases that are refractory to the common therapies by Dexamethasone.

    Sudden sensorineural hearing loss is typically treated with systemic steroids. The aim of this meta-analysis was to evaluate the efficacy of salvage intratympanic steroid treatment in patients who have initial treatment failure with systemic steroids. A MEDLINE literature search was performed, supported by searches of Web of Science, Biosis, and Science Direct. Articles of all languages were included. Selection of relevant publications was conducted independently by three authors. Only randomized controlled trials were considered. In one arm of the studies, the patients received salvage intratympanic steroids. In the other arm, patients did not receive further treatment. The standard difference in mean (SDM) amount of improvement in hearing threshold between patients who did and did not receive salvage intratympanic steroids was calculated. From an initial 184 studies found via the search strategy, 5 studies met inclusion criteria and were included. There was a statistically significant greater reduction in hearing threshold on pure-tone audiometry in patients who received salvage intratympanic steroids than in those who did not (SDM = -0.401, p = 0.005). Subgroup analysis showed that administration by intratympanic injection (SDM = -0.375, p = 0.013) rather than a round window catheter (SDM = -0.629, p = 0.160) yielded significant improvement in outcome. The usage of dexamethasone yielded better outcomes (SDM = -0.379, p = 0.039) than the use of methylprednisolone (SDM = -0.459, p = 0.187). No serious side effect of treatment was reported. In patients who have failed initial treatment with systemic steroids, additional treatment with salvage intratympanic dexamethasone injections demonstrate a statistically significant reduction in the hearing thresholds as compared to controls.

    The most commonly used treatment for sensorineural sudden hearing loss (SSHL) in clinical practice is the administration of steroids; however, a favorable result is not always obtained. We studied 58 patients who failed to recover after primary treatment with IV steroids, 44 of these met our inclusion criteria (mean age 50.7, 27 males, range 30-74). We treated 23 patients (mean age 47.3, 16 males, age range 22-74) with hyperbaric oxygen therapy (HBO) (2.5 ATA for 60 min for 15 treatments), while 21 (mean age 54.5, 11 males, age range 22-71) patients refused to be treated and served as a non-randomized control group. Patients treated with HBO had a mean improvement of 15.6 dB (SD ± 15.3), with 1 of them completely healed, 5 with a good recovery, 10 with a fair recovery and 7 unchanged. Patients who were not treated had a spontaneous mean improvement of 5.0 dB (SD ± 11.4) with 3 patients with a good recovery, 1 patient with a fair recovery and 17 patients unchanged. Mean improvement was significantly better in patients treated with HBO compared to controls (p = 0.0133). Patients with worst hearing had the greater degree of improvement whether or not they were treated in the first 10 days after the onset of the hearing loss or between 11 and 30 days. In conclusion, hyperbaric oxygen therapy can lead to significant improvement of pure tone hearing thresholds in patients with SSHL who failed primary corticosteroid treatment and are within 4 weeks of the onset of deafness.

    Background Blood oxygen level dependent functional magnetic resonance imaging (fMRI) and magnetoencephalography are new techniques of brain functional imaging which can provide the information of excitation of neurons by measure the changes of hemodynamics and electrophysiological data of local brain tissue. The purpose of this study was to study functional brain areas evoked by pure tones in healthy and sensorineural hearing loss subjects with these techniques and to compare the differences between the two groups.Methods Thirty healthy and 30 sensorineural hearing loss subjects were included in this study. In fMRI,block-design paradigm was used. During the active epoch the participants listened to 1000 Hz, sound pressure level 140 dB pure tones at duration 500 ms, interstimulus interval 1000 ms, which presented continuously via a magnetic resonance-compatible audio system. None stimulus was executed in control epoch. In magnetoencephalography study, every subject received stimuli of 1000 Hz tone bursts delivered to the bilateral ear at duration 8 ms, interstimulus intervals 1000 ms. Sound pressure level in healthy subjects was 30 dB; in sensorineural hearing loss subjects was 20 dB above everyone' s hearing threshold respectively. All subjects were examined with 306-channel whole-scalp neuromagnetometer.Results In fMRI, all subjects showed significant activations in bilateral Heschl's gyri, anterior pole of planum temporale, planum temporale, precentral gyri, postcentral gyri, supramarginal gyri, superior temporal gyri,inferior frontal gyri, occipital lobes and cerebellums. The healthy subjects had more intensive activation in bilateral Heschl's gyri, anterior pole of planum temporale, inferior frontal gyri, left superior temporal gyri and fight planum temporale than the hearing loss subjects. But in precentral gyri, postcentral gyri and occipital lobes,the activation is more intensive in the hearing loss subjects. In magnetoencephalography study, both in the

    This study investigated the efficacy of intratympanic steroid (ITS) therapy as a salvage treatment for idiopathic sudden sensorineural hearing loss after failure of intravenous steroid (IVS) therapy. Systemic steroid therapy is the only standard drug therapy. However, ethically, we could not simply compare ITS with IVS. Conventionally, we have treated idiopahic sudden sensorineural hearing loss patients after failure of systemic steroid therapy with the double combined therapy IVS and hyperbaric oxygen (HBO), as the salvage modality. We examined the effect of ITS by adding it to the double combined therapy with IVS and HBO. Retrospectively, we clinically examined the effect of double combined therapy with IVS and HBO (A group) for 31 patients (12 men and 19 women) (median age: 54 years) with sudden hearing loss after failure of systemic steroid therapy between June, 2003 and July, 2010. Prospectively, we also examined clinically the effect of triple combined therapy with IVS and HBO, ITS (B group) for 29 patients (17 men and 12 women) (median age: 51 years) with sudden hearing loss after failure of systemic steroid therapy between August, 2010 and April, 2012. In the examination of patients treated within 30 days from the onset, one patient (3.2%) demonstrated remarkable recovery, 6 patients (19.4%) demonstrated mild recovery, while no change was noted in 24 patients (77.4%) in the A group. In the B group, 5 patients (17.2%) demonstrated complete recovery, 3 patients (10.3%) demonstrated remarkable recovery, mild recovery was seen in 14 patients (48.3%), and the remaining 7 patients (24.1%) showed no change. There was a significant difference (p hearing improvement in group B in five pure tone average was significantly better than in the group A (p hearing improvement than the A group. Therefore, ITS could be effective for idiopathic sudden sensorineural hearing loss patients after failure of systemic steroid therapy.

    The Vibrant soundbridge is a semi-implantable hearing device. The implanted electromagnetic transducer is attached to the incus and it is linked by telemetry to the externally worn audio processor. In Nijmegen, this device has been applied to seven patients with moderate or severe sensorineural hearing loss (PTA between 43 and 71 dB HL) who could not tolerate ear moulds. As the amplification of the device depends on the input level (amplifier with wide dynamic range compression), loudness scaling measurements were performed. The gain as a function of input level was determined from aided and unaided loudness growth curves. The mean gain was 21 dB at an input level of 40 dB SPL. The mean gain decreased to 5 dB at an input level of 90 dB SPL. Measured gain values were lower than target values prescribed by the FIG6 method, mainly however for the low-frequency range and for low-level sounds. It was concluded that this device is very promising for patients who cannot tolerate an ear mould.

    The treatment of sudden sensorineural hearing loss (SSNHL) has remained one of the most controversial issues in otolaryngology, and there are wide disparities between clinicians' treatment methods for SSNHL. Using five-year population-based data, we explored the relationship between physician and hospital characteristics and the length of stay (LOS) for SSNHL patients in Taiwan. The dataset was derived from the National Health Insurance Research Database. The patients in the study sample were identified by a principal diagnosis of sudden hearing loss. A total of 8712 hospitalization cases between 1998 and 2002 inclusive were included. Multiple regression analyses were performed in order to explore the relationship between physician and hospital characteristics and LOS, adjusting for patients' age and gender, as well as complications or comorbidities. The mean LOS for the duration of the study period was 5.62 days, while the regression analysis showed that, as compared to district hospitals, the LOS in medical centers and regional hospitals was 0.42 and 0.37 days longer, respectively (all p patients who were attended by physicians specializing in otolaryngology than for those attended by physicians specializing in other areas (p characteristics and the LOS for SSNHL patients. The results of this study serve to highlight the importance of developing treatment protocols for SSNHL so as to reduce the variation in physician or hospital behavior.

    The purpose of the study was to assess the efficacy of the association of intratympanic (IT) steroid and hyperbaric oxygen (HBO) therapy in patients presenting with idiopathic sudden sensorineural hearing loss (ISSNHL), and to compare this protocol with another consisting of intravenous (IV) steroid administration and HBO therapy. A total of 80 patients diagnosed with ISSNHL were included in this prospective trial. Patients were divided into three categories: a mild-to-moderate ISSNHL group with a pure-tone average (PTA) ≤60 decibels (dB), a severe ISSNHL group with a PTA of 60-80 dB, and a profound ISSNHL group with a PTA ≥81 dB. The first protocol consisted of 20 sessions of HBO therapy together with IV methylprednisolone 1 mg/kg body weight and a 10 mg taper every 3 days for 10 days. The second protocol consisted of HBO therapy for 20 sessions, together with an IT injection of dexamethasone at a dose of 4 mg/mL, 0.5-0.7 mL once a day for 7 consecutive days, performed 3 h before the HBO therapy. In the mild-to-moderate ISSNHL patients, the mean hearing gain and successful treatment rate was 19 (0-27) dB and 78.9 %, respectively in the IT + HBO treatment group, and 18 (3-44) dB and 70.5 % in the IV + HBO therapy group. In the severe ISSNHL patients, the mean hearing gain and successful treatment rate was 33 (1-54) dB and 81.8 %, respectively in the IT + HBO treatment group and 33.5 (7-57) dB and 58.2 % in the IV + HBO group. In the profound ISSNHL patients, the mean hearing gain and successful treatment rate was 36 (4-69) dB and 40 %, respectively in the IT + HBO therapy group, and 39.5 (0-92) dB and 72.7 % in the IV + HBO treatment group. The results demonstrated that patients with severe hearing loss success rate was superior in the group submitted to IT + HBO treatment, conversely IV + HBO therapy may be benefit for patients with profound hearing loss. Nevertheless, these clinical results were not statistically significant.

    This study evaluated the effectiveness of vitamins A, C, and E, with selenium, in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL). This was a prospective, controlled study performed at a tertiary teaching and research hospital. Over a 32-month period, patients were treated with either our standard ISSNHL treatment regimen plus vitamins A, C, and E and selenium (ACE+ group) or with only our standard ISSNHL treatment regimen (ACE- group). The demographics, additional symptoms, mean initial and final hearing levels, mean hearing gain, and recovery data were compared between the two groups. The ACE+ group, consisting of 70 (55.5 %) patients, received vitamin A (natural beta-carotene, 26,000 IU), vitamin C (ascorbic acid, 200 mg), vitamin E (d-alpha-tocopherol, 200 IU), and selenium (50 μg) twice daily for 30 days in addition to our ISSNHL treatment regimen: methylprednisolone at an initial dose of 1 mg/kg body weight per day, tapered over 14 days; Rheomacrodex(®) [(10 g of dextran and 0.9 g of NaCl)/100 ml] 500 ml daily for 5 days; Vastarel(®) 20-mg tablet (20 mg of trimetazidine dihydrochloride) three times daily for 30 days; and ten 60-min hyperbaric oxygen (HBO) sessions (2.5 absolute atmospheres of 100 % O2), once daily, starting the day of hospitalization. The ACE- group comprised 56 (44.4 %) patients, who received only our ISSNHL treatment regimen. The mean hearing gains were 36.2 ± 20.3 dB in the ACE+ group and 27.1 ± 20.6 dB in the ACE- group. The mean hearing gain rates were significantly higher in the ACE+ group than in the ACE- group (p = 0.014). Treatment with vitamins A, C, and E and selenium was effective in ISSNHL patients undergoing treatment with methylprednisolone, dextran, trimetazidine dihydrochloride, and HBO, and might be more effective when the initial hearing level is below 46 dB.

    The auditory system is capable of perceptually restoring inaudible portions of speech. This restoration may be compromised as a result of hearing impairment, particularly if it is combined with advanced age, because of degradations in the bottom-up and top-down processes.

    To investigate how hearing loss affects the loudness of brief tones, loudness matches between 5- and 200-ms tones were obtained as a function of level. Loudness functions derived from these data indicated that the gain required to restore loudness usually is the same for short and long sounds....

    Involvement of the middle ear after viral infections of the upper airways may lead to serous otitis media with effusion in the absence of bacterial infection. This can be accompanied by a concomitant shading of the mastoid air cells, which could manifest as a reduced opacity on computed tomography (CT) in the absence of a history of chronic mastoiditis or acute inflammatory signs. This can lead to a subsequent impairment of inner ear function. CT scans reveal an extended pneumatization of the temporal bones in affected patients. Inner ear hearing impairment can probably be attributed to a concomitant labyrinthine reaction-the so-called toxic inner ear lesion. If no remission occurs within 5 days after initial conservative treatment (paracentesis or hemorrheologic infusions), surgical treatment with a mastoidectomy can accelerate hearing restoration. We conducted a retrospective, nonrandomized study of short- and long-term hearing outcomes in patients with a toxic inner ear lesion who had been treated with conservative measures alone (CONS group) or with surgery (SURG group) in a tertiary care referral center. Our study group was made up of 52 consecutively presenting patients (57 ears) who had been seen over a 10-year period; there were 20 patients (21 ears) in the CONS group and 32 patients (36 ears) in the SURG group. Initially, 15 CONS patients (75%) and 18 SURG patients (56%) complained of dizziness or a balance disorder. The initial averaged sensorineural hearing loss (over 0.5, 1.0, 2.0, and 3.0 kHz) was 32.4 ± 15.6 dB in the CONS group and 35.4 ± 12.0 dB in the SURG group. At follow-up (mean: 31.7 mo), the SURG group experienced a significantly greater improvement in hearing (p = 0.025). We conclude that patients with viral otitis media and concomitant noninflammatory mastoiditis with impairment of inner ear function (sensorineural hearing loss) experience a better hearing outcome when a mastoidectomy is performed during primary treatment.

    Abstract The etiology of sudden sensorineural hearing loss (SSNHL) remains unclear in most cases. This study aimed to assess abnormal magnetic resonance imaging (MRI) findings in patients with SSNHL and evaluate the value of MRI in identifying the cause of SSNHL. A retrospective analysis of the charts and MRI findings of 291 patients with SSNHL was performed. In 291 patients, MRI abnormality, which was considered a cause of SSNHL, was detected in 13 patients. Vestibular schwannoma involving the internal auditory canal (IAC) and/or cerebellopontine angle was observed in 9 patients. All 9 patients had intrameatal tumors, and 6 of the 9 patients displayed extrameatal extension of their tumors. The tumor was small (<1 cm) or medium-sized (1.1–2.9 cm) in these 6 patients. Intralabyrinthine schwannoma, labyrinthine hemorrhage, IAC metastasis, and a ruptured dermoid cyst were each observed in 1 patient. The most commonly observed MRI abnormality in patients with SSNHL was vestibular schwannoma, and all of the lesions were small or medium-sized tumors involving the IAC. PMID:27124066

    Tinnitus-related distress appears to be more strongly associated with multiple psychological factors than with any perceptual properties of tinnitus. Prior studies have not investigated the role of worry in tinnitus sufferers. Worry is a dispositional cognitive trait that involves a pervasive, non-specific, future-oriented proneness to fretting, which can foster negative affective states and catastrophic thinking about a specific trouble when the trouble is actual and present. We examined the relationship between worry and self-perceived anxiety and depressive symptoms and handicap in 54 outpatients with chronic tinnitus and sensorineural hearing loss who had been previously recruited for a randomized double-blind study on the efficacy of transmeatal low-level laser therapy for tinnitus. We measured the current anxiety and depressive symptoms with the State-Trait Anxiety Inventory Form Y-1/Self-evaluation Depression Scale, the handicap with the Tinnitus Handicap Inventory, and the proneness to worry with the Penn State Worry Questionnaire. For the psychoacoustic tinnitus measures, we considered the loudness match and the minimum masking level. We found that tinnitus-related anxiety and depressive symptoms and handicap were significantly associated with proneness to worry (linear regression models, p tinnitus in clinical practice. Early therapeutic interventions for reducing proneness to worry may facilitate better adaptation to tinnitus.

    There are few accounts of cochlear implantation in adults with post-traumatic sensorineural hearing loss. We report our experience with multichannel implantation in three such patients. Two patients experienced no cognitive or communication deficits as a result of their head injury. At nine months post-implant, compared with our experience of non-head-injured implantees, these patients achieved average or above average scores on audiological performance tests. The third patient presented with cognitive, behavioural and communicative deficits. The level of improvement achieved by this patient, when lip-reading was supplemented with electrical stimulation, in both BKB sentence and connected discourse tracking (CDT) tests was comparable with that of the non-head-injured group. However, his absolute performance at nine months post-implant was well below average. Performance at 18 months on BKB sentences and environmental sound recognition showed little change, and was again well below average, however his score on CDT with lip-reading and electrical stimulation improved considerably and was similar to the average achieved by the non-head-injured group. The major difficulties experienced with this patient were increasing depression and low implant use. Considerably more time was spent in the assessment and rehabilitation of this patient and involved liaison with a number of other agencies. When considering such patients for cochlear implantation it is strongly recommended that these additional requirements are taken into account.

    We aimed to examine the prevalence of cerebellar tonsil ectopia and Chiari 1 malformation in sensorineural hearing loss (SHL) that has, to the best of our knowledge, not been studied previously. Magnetic resonance imaging records of 166 subjects with SHL and 50 controls without known otologic disturbances were included in the study. A tonsils descent more than 2 mm was assumed as cerebellar ectopia, and a descent equal to or more than 5 mm was assumed as Chiari 1 malformation. A tonsil descent group was also formed by summation of both groups. Transverse diameters of bilateral intracranial vertebral arteries and transverse sinuses were also measured, and all parameters were analyzed using appropriate statistics. A significant difference of frequencies of Chiari 1, ectopia, and tonsil descent was detected between patients and controls. In comparison of cerebellar ectopia and Chiari 1 groups, SHL did not show any significant difference. The left lateral sinus diameter showed positive correlation with tonsil descent. There was no significant correlation for the diameters of other vessels. A powerful correlation was detected between SHL and age. In addition, right and vertebral artery diameters showed positive correlations with age. Chiari 1 malformation and cerebellar ectopia showed an association with SHL. These patients should also be evaluated for otologic disturbances. Further high-resolution magnetic resonance imaging studies to explain the exact cause of this currently unknown association seems required.

    Sensorineural hearing loss (SNHL) is a significant neurologic morbidity in survivors of neonatal congenital diaphragmatic hernia (CDH), with a reported incidence of up to 60%. In a historical cohort study of 37 neonates with CDH, we investigated the use of pancuronium bromide (PB) and common ototoxic drugs during the neonatal period and their relationship to SNHL in childhood survivors. Survivors with SNHL (n = 23) had significantly higher cumulative dose of PB administered during the neonatal illness than survivors without SNHL (n = 14). The cumulative dose and duration of PB use significantly correlated (r = 0.66-0.81) and independently predicted (adjusted r (2) = 0.42-0.64) the greatest intensity (in decibels) and the widest band (lowest frequency in hertz) loss of SNHL. No differences were identified between survivors with and without SNHL regarding demographic and neonatal characteristics (including oxygenation and ventilation variables and the cumulative dose and duration of therapy with aminoglycosides, vancomycin, and furosemide), although survivors with SNHL had received a modestly higher cumulative dose of ethacrynic acid than survivors without SNHL. Although we show that prolonged administration of PB during the neonatal period is associated with SNHL in childhood survivors of CDH, further multicenter studies are required to investigate the possible etiologies of SNHL in this high-risk population.

    . In this report, we describe two new 17q23.2 deletion patients with mild intellectual disability and sensorineural hearing loss. They both had submicroscopic deletions smaller than the common deleted region for the 8 previously described 17q23.2 microdeletion cases. TBX4 was previously suggested...... as the responsible gene for the heart or limb defects observed in 17q23.2 deletion patients, but the present cases do not have these features despite deletion of this gene. The finding of sensorineural hearing loss in 5 of the 10 cases, including the present cases, with a microdeletion at17q23.2, strongly suggests...... the presence of a candidate gene for hearing loss within this region. We screened 41 patients with profound sensorineural hearing loss for mutations of TBX2 and detected no mutations....

    A retrospective chart review to assess the effectiveness of hyperbaric oxygen treatment in sudden sensorineural hearing loss. 44 patients aged between 17-67 years diagnosed with idiopathic sensorineural hearing loss less than 30 days were admitted to our clinic Patients were treated with systemic steroid alone or systemic steroid plus hyperbaric oxygen therapy. In the comparison of two groups, there was no statistically significant difference of audiometric evaluation (P>0.0028) found in hearing improvement for each frequency on 5th day of the treatment and post treatment. Age (≤45 and >45) and initial hearing level (≤60 dB. And >60 dB.) does not seem to be an influential factor according to the results of the study (P>0.0007). The present study did not show more superior healing effect of hyperbaric oxygen therapy added to systemic steroid therapy than steroid infusion alone. The results are consistent with those of some papers. However there are also conflicting data that support significant effect of hyperbaric oxygen therapy. Routine administration of this therapy seems to be unnecessary in view of these results.

    Full Text Available Background. Even if various pathophysiological events have been proposed as explanations, the putative cause of sudden hearing loss remains unclear. Objectives. To investigate and to reveal associations (if any between the main iron-related gene variants and idiopathic sudden sensorineural hearing loss. Study Design. Case-control study. Materials and Methods. A total of 200 sudden sensorineural hearing loss patients (median age 63.65 years; range 10–92 were compared with 400 healthy control subjects. The following genetic variants were investigated: the polymorphism c.−8CG in the promoter of the ferroportin gene (FPN1; SLC40A1, the two isoforms C1 and C2 (p.P570S of the transferrin protein (TF, the amino acidic substitutions p.H63D and p.C282Y in the hereditary hemochromatosis protein (HFE, and the polymorphism c.–582AG in the promoter of the HEPC gene, which encodes the protein hepcidin (HAMP. Results. The homozygous genotype c.−8GG of the SLC40A1 gene revealed an OR for ISSNHL risk of 4.27 (CI 95%, 2.65–6.89; P=0.001, being overrepresented among cases. Conclusions. Our study indicates that the homozygous genotype FPN1 −8GG was significantly associated with increased risk of developing sudden hearing loss. These findings suggest new research should be conducted in the field of iron homeostasis in the inner ear.

    Full Text Available Introduction: Sudden sensorineural hearing loss is a confusing and controversial issue in our practice since no standard definition, evaluation method and treatment protocol exists. It is an otological emergency with narrow golden period of treatment. Objective: To establish the early diagnosis, treatment and study the outcome of treatment. Design and Method: In a prospective study, including patients >18 year age who had presented with sudden sensorineural hearing loss in ENT opd; after ENT examination, PTA, impedance audiometry and necessary imaging, were treated with i.v. methylprednisolone and inj.methylcobalamine i.m. along with tablet Pentoxyfylline and tablet prednisolone. PTA was repeated on 4th day, 3 week, and 6 weeks after diagnosis. Results: Total 37 patients were diagnosed and treated. Majority of patients had sudden SNHL of <72 hrs. duration with severe hearing loss and tinnitus as commonest associated symptom. Idiopathic cause was commonest followed by acoustic trauma and head trauma. 35.14% patients had complete recovery while 40.54% and 24.32% patients had partial and no recovery respectively. Conclusion: PTA is single most important investigation. Prompt treatment in <72 hrs. carry good prognosis. Associated vertigo, flat audiogram, DM, HTN are of poor prognosis.

    A method for the treatment of chronic sensorineural hearing loss (CSNHL) is proposed that includes administration of trental followed by intravenous laser irradiation of blood (IVLBI). The study included 81 patients at the age from 20 to more than 60 years presenting with CSNHL. They were allocated to three groups; the patients in group 1 (n=32) were given trental intravenously followed by intravenous laser irradiation of blood, those of group 2 (n=24) were treated with IVLBI alone while patients of group 3 (n=25) received "traditional" treatment. Audiometric examination and rheoencephalography were carried out before and after therapy. The hearing improved to 18-20 dB in group 1, to 10-15 dB in group 2, and to 10 dB in group 3. The improvement of rheoencephalographic characteristics was documented in the patients of all groups but was especially pronounced in group 1. It is concluded that the proposed method significantly increases the efficiency of treatment of chronic sensorineural hearing loss.

    CDH23 mutations have mostly been associated with prelingual severe-to-profound sensorineural hearing loss (SNHL) in either syndromic or nonsyndromic SNHL (DFNB12). Herein, we demonstrate the contribution of CDH23 mutations to postlingual nonsyndromic SNHL (NS-SNHL). We screened 32 Korean adult probands with postlingual NS-SNHL sporadically or in autosomal recessive fashion using targeted panel or whole exome sequencing. We identified four (12.5%, 4/32) potential postlingual DFNB12 families that segregated the recessive CDH23 variants, qualifying for our criteria along with rapidly progressive SNHL. Three of the four families carried one definite pathogenic CDH23 variant previously known as the prelingual DFNB12 variant in a trans configuration with rare CDH23 variants. To determine the contribution of rare CDH23 variants to the postlingual NS-SNHL, we checked the minor allele frequency (MAF) of CDH23 variants detected from our postlingual NS-SNHL cohort and prelingual NS-SNHL cohort, among the 2040 normal control chromosomes. The allele frequency of these CDH23 variants in our postlingual cohort was 12.5%, which was significantly higher than that of the 2040 control chromosomes (5.53%), confirming the contribution of these rare CDH23 variants to postlingual NS-SNHL. Furthermore, MAF of rare CDH23 variants from the postlingual NS-SNHL group was significantly higher than that from the prelingual NS-SNHL group. This study demonstrates an important contribution of CDH23 mutations to poslingual NS-SNHL and shows that the phenotypic spectrum of DFNB12 can be broadened even into the presbycusis, depending on the pathogenic potential of variants. We also propose that pathogenic potential of CDH23 variants and the clinical fate of DFNB12 may be predicted by MAF. PMID:27792758

    Anxiety disorder (AD) is commonly associated with a number of physical illnesses. No previous study has investigated the association between AD and sudden sensorineural hearing loss (SSNHL). In this study, we investigated the association between prior AD and SSNHL using a population-based dataset in Taiwan. Sampled subjects of this case-control study were retrieved from the Taiwan "Longitudinal Health Insurance Database". We identified 3,522 patients who had a diagnosis of SSNHL as cases and 10,566 age- and gender-matched subjects without SSNHL as controls. A conditional logistic regression was used to calculate the odds ratio (OR) for having previously been diagnosed with AD between cases and controls. We found that of 14,088 patients, 13.4% had a prior AD diagnosis, 17.8 and 11.9% for the SSNHL group and controls, respectively. After adjusting for patient socioeconomic characteristics and comorbid medical disorders, SSNHL patients were more likely to have prior AD than the controls (OR 1.49, 95% confidence interval (CI) 1.34-1.66, p < 0.001). Furthermore, we found that the significant relationship between SSNHL and prior AD decreased with age. The relationship was the most pronounced among those aged ≤44 years, with an adjusted OR of 1.86 (95% CI 1.48-2.33, p < 0.001) for cases compared to controls. We concluded that patients with SSNHL had a higher proportion of prior AD than non-SSNHL-diagnosed controls. Further study is needed to confirm our findings and explore the underlying pathomechanisms.

    Full Text Available Ulcerative colitis (UC is characterized by an inflammatory disorder of the gastrointestinal tract. Immune-mediated extraintestinal manifestations of UC have increasingly attracted attention in the literature recently, for which UC is now considered as a systemic disease. Neurologic involvement associated with UC is probably under-reported because of the unawareness of many physicians, although early recognition and treatment are crucial in preventing major morbidity and sequel. In this case report is presented a patient newly diagnosed as UC, who developed both sensorineural hearing loss and intractable status epilepticus that we suggest to have resulted from immune-mediated mechanisms.

  5. Lipid profiles and obesity as potential risk factors of sudden sensorineural hearing loss.

    Joong Seob Lee

    Full Text Available The objective of our study was to establish whether increased lipid profiles and obesity affect the prevalence and prognosis of sudden sensorineural hearing loss (SSNHL.This was a case-controlled study with a longitudinal design. According to our criteria, 324 patients with SSNHL were included in this study. To manage potential covariates, 972 subjects with normal hearing from the Korean National Health and Nutrition Examination Survey were matched as control group according to their propensity scores. Age, level of total cholesterol (TC, high density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C, triglycerides (TG, and body mass index (BMI were obtained from the clinical data. Multivariate logistic regression analysis was used to investigate the association between SSNHL and lipid profiles or obesity in the 1296 subjects. Multivariate Cox regression analysis was used to determine whether lipid profiles and obesity are prognostic factors in patients with SSNHL.Mean body weight, BMI, TC, and TG were significantly higher in patients with SSNHL compared with control subjects (p<0.05. However, LDL-C values did not differ significantly between the two groups. Subjects with elevated TC and TG levels had a 2.20- (95% CI 1.50-3.24 and 1.50-fold (95% CI 1.08-2.08 increased odds, respectively, of SSNHL compared with subjects with normal TC and TG levels. Subjects with grade III BMI had a 1.59-fold (95% CI 1.17-2.16 increased odds of SSNHL. Multivariate Cox regression analyses revealed that BMI was an independent risk factor of treatment outcome, as patients with BMI ≥27.5 were less likely to achieve complete recovery than those with BMI <27.5 (p<0.05.The results of this study revealed that elevated TC and TG levels and increased BMI are significantly associated with the prevalence of SSNHL and its prognosis, indicating that vascular compromise may play an important role in the pathogenesis of SSNHL.

    Full Text Available Background and Aim: Among all auditory assessment tools, auditory steady state response (ASSR is a modern test. Modulation frequency for this test is usually 80 Hz. The purpose of this study, was to examined adult subjects with 40 Hz and 80 Hz ASSR and compare the results.Materials and Methods: Thirty adult (60 ears were evaluated by ASSR and PTA test, Results were divided into three groups: normal hearing, mild and moderate sensorineural hearing loss. Results: In all groups, forty hertz ASSR thresholds were relatively closer to behavioral threshold than those of 80 Hz ASSR(p<0.05. Besides, the more severe hearing loss, the lower the difference between those two thresholds. Correlation coefficients were also higher in 40 Hz ASSR(p<0.05. Conclusion: Frequency modulation thresholds with 40 Hz are more likely to be closer to the behavioral thresholds. Moreover, it has better results than the thresholds with 80 Hz.

    2016-01-01

    Idiopathic sudden sensorineural hearing loss (ISSHL), a common otologic emergency, presents mostly as an abrupt onset unilateral hearing loss, aural fullness, often with vertigo and tinnitus, usually upon awakening in the morning. Its etiopathogenesis is multifactorial, so a number of different therapeutic regimens are in practice, hyperbaric oxygen (HBO2) therapy being an effective yet underutilized one. Not all cases recover completely even after treatment. Here we describe two cases of ISSHL, diagnosed on the basis of clinical examination and pure-tone audiometry, who had a complete recovery following administration of HBO2 therapy in addition to medical treatment. These cases are reported to highlight the effectiveness of this modality in a physician's armamentarium.

  9. Sudden sensorineural hearing loss and vertigo associated with arterial occlusive disease: three case reports and literature review

    Directory of Open Access Journals (Sweden)

    Ney Penteado de Castro Junior

    Full Text Available Sudden sensorineural hearing loss and vertigo (SSNHLV has multifactorial causes, of which viral, autoimmune and vascular insufficiency are the most common. The therapeutic management for SSNHLV includes antiviral drugs, corticosteroids, vasodilators, normovolemic hemodilution therapy and hyperbaric oxygen therapy. Vertebrobasilar occlusive disease and carotid occlusive disease are seldom related to SSNHLV. Discussions concerning SSNHLV caused by occlusive vascular disease are important and necessary for both neurologists and otolaryngologists, since their therapeutic management and prognosis are very different from other causes of hearing loss and vertigo. Here, we present our experience with three cases managed with interventional treatment and conduct a review and discussion on the relevant literature. We conclude that investigation of vertebrobasilar and carotid occlusive diseases is necessary in patients over 50 years of age who present SSNHLV, mild neurological symptoms and a history of arteriosclerosis, high blood pressure or thrombosis.

    Objective: Aimed to compare the outcome in patients with acute low-tone sensorineural hearing loss (ALHL) treated with different doses of glucocorticoids. Method: Fifty-four ALHL patients were randomly divided into no-prednisone group(n=: ten) , low-dose prednisone groupCn = 22) and high-dose prednisone group(n = 22). AH patients were treated for ten days and followed up for six months from the initial examination. Result;The cure rates (complete recovery) were 30. 0%, 59. 1%. 90. 9% respectively and the improved rates (complete recovery and partial recovery) were 40.0%, 86.4%. 95.5% respectively in the three groups of no prednisone group, low-dose prednisone group and high-dose prednisone group. The low-dose prednisone group therapy for ALHL showed significant improved rates than the no prednisone group(P<0. 05). The high-dose prednisone group therapy for ALHL showed significant cure rates than the low-dose prednisone group (P<0. 05). Conclusion; High-dose glucocorticoids is more effective than low dose. It is suggested that the etiology of ALHL is related with both an en-dolymphatic hydrops and an autoimmunological mechanism.%目的:探讨不同剂量糖皮质激素在治疗急性低频下降型感音神经性聋(ALHL)中的疗效差异.方法:选取54例(54耳)ALHL患者,随机分为无泼尼松组(10例)、低剂量泼尼松组(22例)和高剂量泼尼松组(22例),治疗10d,并随访6个月.结果:无泼尼松组、低剂量泼尼松组和高剂量泼尼松组痊愈率分别为30.0%、59.1%、90.9%,高、低剂量组比较差异有统计学意义(P<0.05);改善率分别为40.0%、86.4%、95.5%,低剂量、高剂量泼尼松组与无泼尼松组比较均差异有统计学意义(均P<0.05).结论:用糖皮质激素治疗ALHL疗效显著,高剂量优于低剂量,提示该病与内淋巴水肿和患者自身免疫机制可能相关.

    2009-12-01

    Full Text Available This randomized clinical trial aimed to assess the efficacy of phlebotomy on improvement of hearing loss. 71 patients with sudden sensorineural hearing loss were enrolled in this randomized clinical trial study. They were divided into two groups: group A received steroid and hydration therapy plus phlebotomy, while group B received the same regimen without phlebotomy. They were matched according to sex, age, Hb, and Htc. Pure tone audiometries were administered to examine the hearing levels before and after treatment. Statistical analysis showed higher improvement in 250-1000 Hz in patients whit phlebotomy (P<0.001. However, there was noticed no significant difference in hearing improvement in 2000-8000 Hz between two methods. The number (% of patients who had improvement was 29(85.3% in phlebotomy group and 21(56.8% in non-phlebotomy group. On the other hand, the number (% of patients who showed no improvement in A and B group was 5(14.7% and 16(43.2%, respectively (P=0.008. Using phlebotomy accompanied by steroid and hydration therapy leads to higher improvement in hearing loss especially in 250-1000 Hz. We think that this method has the ability to achieve better result in the management of patients with SSNHL.

  13. Ipsilateral distortion product otoacoustic emission (2f1-f2) suppression in children with sensorineural hearing loss.

    2003-08-01

    Distortion product otoacoustic emission (DPOAE) ipsilateral suppression has been applied to study cochlear function and maturation in laboratory animals and humans. Although DPOAE suppression appears to be sensitive to regions of specialized cochlear function and to cochlear immaturity, it is not known whether it reflects permanent cochlear damage, i.e., sensorineural hearing loss (SNHL), in a reliable and systematic manner in humans. Eight school-aged children with mild-moderate SNHL and 20 normal-hearing children served as subjects in this study. DPOAE (2f1-f2) suppression data were collected at four f2 frequencies (1500, 3000, 4000, and 6000 Hz) using moderate-level primary tones. Features of the DPOAE iso-suppression tuning curves and suppression growth were analyzed for both subject groups. Results show that DPOAE suppression tuning curves from hearing-impaired subjects can be reliably recorded. DPOAE suppression tuning curves were generally normal in appearance and shape for six out of eight hearing-impaired subjects but showed subtle abnormalities in at least one feature. There was not one single trend or pattern of abnormality that characterized all hearing-impaired subjects. The most prominent patterns of abnormality included: broadened tuning, elevated tip, and downward shift of tip frequency. The unique patterns of atypical DPOAE suppression in subjects with similar audiograms may suggest different patterns of underlying sensory cell damage. This speculation warrants further investigation.

    The association between idiopathic sudden sensorineural hearing loss (ISSNHL) and the radiologic characteristics of the vertebrobasilar artery is unclear. We hypothesized that the degree and direction of vertebrobasilar artery curvature in the posterior circulation contribute to the occurrence of ISSNHL. We consecutively enrolled patients diagnosed with unilateral ISSNHL in two tertiary hospitals. Magnetic resonance images were performed in all patients to exclude specific causes of ISSNHL, such as vestibular schwannoma, chronic mastoiditis, and anterior inferior cerebellar artery infarct. We measured the following parameters of posterior circulation: vertebral and basilar artery diameter, the degree of basilar artery curvature (modified smoker criteria), and vertebral artery dominance. Pure tone audiometries were performed at admission and again 1 week and 3 months later. A total of 121 ISSNHL patients (mean age, 46.0 ± 17.3 years; 48.8% male) were included in these analyses. The proportion of patients with the left side hearing loss was larger than the proportion with the right side hearing loss (left, 57.9%; right, 42.1%). The majority of patients were characterized by a left dominant vertebral artery and right-sided basilar artery curvature. The direction of the basilar artery curvature was significantly associated with hearing loss lateralization (p = 0.036). Age and sex matched multivariable analyses revealed the absence of diabetes and right-sided basilar artery curvature as significant predictors for left sided hearing loss. There was no statistical difference between atherosclerotic cardiovascular risk score (high versus low) and hearing outcomes at 3 months. In ISSNHL, the laterality of hearing loss was inversely associated with the direction of basilar artery curvature. Our results, therefore, indicate the importance of vascular assessment when evaluating ISSNHL.

  16. Synaptopathy in the noise-exposed and aging cochlea: Primary neural degeneration in acquired sensorineural hearing loss.

    The classic view of sensorineural hearing loss (SNHL) is that the "primary" targets are hair cells, and that cochlear-nerve loss is "secondary" to hair cell degeneration. Our recent work in mouse and guinea pig has challenged that view. In noise-induced hearing loss, exposures causing only reversible threshold shifts (and no hair cell loss) nevertheless cause permanent loss of >50% of cochlear-nerve/hair-cell synapses. Similarly, in age-related hearing loss, degeneration of cochlear synapses precedes both hair cell loss and threshold elevation. This primary neural degeneration has remained hidden for three reasons: 1) the spiral ganglion cells, the cochlear neural elements commonly assessed in studies of SNHL, survive for years despite loss of synaptic connection with hair cells, 2) the synaptic terminals of cochlear nerve fibers are unmyelinated and difficult to see in the light microscope, and 3) the degeneration is selective for cochlear-nerve fibers with high thresholds. Although not required for threshold detection in quiet (e.g. threshold audiometry or auditory brainstem response threshold), these high-threshold fibers are critical for hearing in noisy environments. Our research suggests that 1) primary neural degeneration is an important contributor to the perceptual handicap in SNHL, and 2) in cases where the hair cells survive, neurotrophin therapies can elicit neurite outgrowth from spiral ganglion neurons and re-establishment of their peripheral synapses.

    Early hearing deprivation could affect the development of auditory, language, and vision ability. Insufficient or no stimulation of the auditory cortex during the sensitive periods of plasticity could affect the function of hearing, language, and vision development. Twenty-three infants with congenital severe sensorineural hearing loss (CSSHL) and 17 age and sex matched normal hearing subjects were recruited. The amplitude of low frequency fluctuations (ALFF) and regional homogeneity (ReHo) of the auditory, language, and vision related brain areas were compared between deaf infants and normal subjects. Compared with normal hearing subjects, decreased ALFF and ReHo were observed in auditory and language-related cortex. Increased ALFF and ReHo were observed in vision related cortex, which suggest that hearing and language function were impaired and vision function was enhanced due to the loss of hearing. ALFF of left Brodmann area 45 (BA45) was negatively correlated with deaf duration in infants with CSSHL. ALFF of right BA39 was positively correlated with deaf duration in infants with CSSHL. In conclusion, ALFF and ReHo can reflect the abnormal brain function in language, auditory, and visual information processing in infants with CSSHL. This demonstrates that the development of auditory, language, and vision processing function has been affected by congenital severe sensorineural hearing loss before 4 years of age.

    The main objective of the meta-analysis was to investigate whether intratympanic steroid injections in combination with systemic steroids would provide an additional advantage over systemic steroid therapy (SST) alone in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). The results will provide a meaningful suggestion in clinical therapy of ISSNHL. The electronic database search was based on the database in OVID Medline, Embase and PubMed up to December 15, 2015 with the goal of identifying all available observational studies examining the effects of combination therapy and SST in ISSNHL patients. Observational studies that compared the pure tone average (PTA) improvement and recovery rate between combination therapy and SST group in ISSNHL patients were selected. Finally we have identified eight eligible studies that focused on comparing the combination therapy and SST in ISSNHL from designated researches. In the PTA improvement group, seven studies have been analyzed to compare the pooled mean differences between two therapy modalities and subgroups based on initial hearing loss and treatment delay. In the recovery rate group, six studies were calculated for pooled risk ratios and subgroup analysis was also conducted. Through our meta-analysis, we have reached the conclusion that combination therapy exhibited better outcomes in PTA improvement than SST alone, especially in severe-profound initial hearing loss cases. Combination therapy also showed advantages in recovery rate. Whether time of treatment delay would influence the PTA improvement and recovery rate requires further researches.

    Objective:To evaluate the efficacy and safety of intratympanic and systemic steroid therapies in the initial treatment of Sudden Sensorineural Hearing Loss (SSNHL) patients. Methods:A comprehensive search of PubMed, Wanfang database and CNKI (China National Knowledge Infrastructure) was performed covering the period from January 1990 to July 2014. A meta-analysis was conducted after filtering by the criteria of Cochrane Collaboration. Three hundred fifty six subjects in nine studies allocated to the group of intratympanic steroid therapies and 343 controls receiving systemic steroid therapies met the criteria for meta-analysis. The data were extracted and analyzed using the RevMan 5.3 meta-analysis software. Results: The total effectiveness rate in SSNHL patients receiving intratympanic steroid therapies did not differ statistically from patients receiving systemic therapies (RR ¼ 1.08, 95%CI ¼ 0.99e1.99, P ¼ 0.10), although the rate of full hearing recovery in this group differed significantly from patients receiving systemic therapies (RR ¼ 1.29, 95%CI ¼ 1.00e1.66, P ¼ 0.05). Conclusion: Local steroid therapy appears to generate higher rate of complete hearing recovery than systemic steroid treatment as an initial treatment for SSNHL, which may be especially useful for patients in whom systemic steroids are contraindicated.

    Meniere's disease is an episodic vestibular syndrome associated with sensorineural hearing loss (SNHL) and tinnitus. Patients with MD have an elevated prevalence of several autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis and psoriasis), which suggests a shared autoimmune background. Functional variants of several genes involved in the NF-κB pathway, such as REL, TNFAIP3, NFKB1 and TNIP1, have been associated with two or more immune-mediated diseases and allelic variations in the TLR10 gene may influence bilateral affectation and clinical course in MD. We have genotyped 716 cases of MD and 1628 controls by using the ImmunoChip, a high-density genotyping array containing 186 autoimmune loci, to explore the association of immune system related-loci with sporadic MD. Although no single nucleotide polymorphism (SNP) reached a genome-wide significant association (phearing loss progression in patients with unilateral SNHL. So, individuals with unilateral MD carrying the C allele in rs3774937 or G allele in rs4648011 had a shorter mean time to reach hearing stage 3 (>40 dB HL) (log-rank test, corrected p values were p = 0.009 for rs3774937 and p = 0.003 for rs4648011, respectively). No variants influenced hearing in bilateral MD. Our data support that the allelic variants rs3774937 and rs4648011 can modify hearing outcome in patients with MD and unilateral SNHL.

    The effect of intratympanic steroid injection is controversial as salvage or initial treatment option for sudden sensorineural hearing loss (SSNHL) and almost unknown if it is consecutively to use after initial systemic steroids. This study aimed to analyze the efficiency of intratympanic dexamethasone injection (ITDI) as a sequential treatment in the patients who failed initial systemic steroid treatments for SSNHL. Forty-six patients with SSNHL who did not respond to initial systemic steroids were prospectively included in the study. The patients were randomly classified into two groups; the ITDI group (21 patients) did not take four sequential ITDI within 2 weeks after systemic steroids, and the control group (25 patients) took any more medications. Hearing improvement was defined as a 10 dB or more decrease in the pure tone average (PTA) of the four-frequencies (0.5, 1, 2, and 3 kHz). Hearing improvement was observed in 10 (47.6%) of 21 ITDI patients and in 4 (16.0%) of 25 control patients (P = 0.027). An improvement of the mean PTA was 11.4 dB in the ITDI group and 1.7 dB in the control group (P = 0.004). The ITDI group showed significant hearing improvement at low frequency (500 Hz) than the control group. The patients with 70 or more dB in PTA before ITDI showed significant hearing improvement than the other patients with better PTAs (P = 0.038). The sequential ITDI, which is performed immediately after initial systemic steroid therapy, may be a simple, effective second-line treatment of choice for the patients who show poor response to initial treatments for SSNHL.

    This prospective study involved 79 homozygote and heterozygote sickle cell anaemia patients (16 to 50 years old) and a control group of 40 people.All patients underwent ENT, audiological and brainstem auditory evoked responses (BSER) examinations in order to evaluate the incidence of sensorineural hearing loss (SNHL), to identify the changes at the level of the cochlear nerve and the central pathways, and to determine the most vulnerable group, in order to intervene with early prevention and rehabilitation for this condition.A hearing loss of greater than 20 dB at two or more frequencies was found in 36 (45.57 per cent) sickle cell patients (19 (47.22 per cent) HbSC patients and 17 (43.59 per cent) HbSS patients) and three (7.5 per cent) members of the control group. Homozygote and heterozygote patients, as well as both sexes, were equally affected. Bilateral hearing loss occurred in 19 (52.78 per cent) patients, unilateral right-sided hearing loss in five (13.89 per cent) patients and unilateral left-sided hearing loss in 12 (33.33 per cent) patients. Brainstem auditory evoked potential demonstrated a prolonged I-V (III-V) interpeak latency in 13 (25.35 per cent) sickle cell patients (11 men (eight with HbSS) and two women). The hearing loss in HbSS patients was neural in nature and of earlier onset; the hearing loss in HbSC patients was usually cochlear in nature and of later onset. Despite high medical standards and 100 per cent social security cover, the high incidence of SNHL in our sickle cell affected patients (the majority with the Benin haplotype) was probably due to their specific haematological profile and to the original geographical distribution of the disease in the tropics. Our results highlight the necessity for early and regular hearing assessment of sickle cell patients, including BSER examination, especially in male patients with SNHL.

    Full Text Available 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.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.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.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

    Full Text Available Vários fatores têm sido postulados como causa da surdez súbita idiopática. Por meio de uma revisão bibliográfica foi feita uma análise crítica quanto aos aspectos etiológicos e fisiopatogênicos desta manifestação clínica. Estudos atuais sugerem que os distúrbios vasculares, a ruptura de membranas da orelha interna e as doenças auto-imunes são possíveis causas, mas a afecção viral tem recebido maior atenção nos últimos anos, embora ainda pouco se conheça sobre os mecanismos da surdez súbita idiopática. Os vírus podem causar a perda súbita da audição na infecção aguda, mas a forma latente, com uma possível reativação viral, também tem sido considerada no mecanismo de agressão à cóclea. Apesar de uma alteração da viscosidade sangüínea poder explicar a perda auditiva, estudos experimentais e clínicos não mostram sinais de ossificação e de fibrose na cóclea ou de ruptura de membranas do labirinto. Estes fatos contrapõem, respectivamente, a teoria vascular e a da fístula labiríntica. A eventual presença de anticorpos contra a orelha interna sugere que a surdez súbita idiopática possa ser de natureza auto-imune, fato este também não confirmado pela falta de relação entre os aspectos clínicos e morfológicos da doença auto-imune e da perda auditiva. A surdez súbita idiopática é, ainda, um tema controverso e obscuro em diversos aspectos.Several factors have been postulated to elicit the etiology of idiopathic sudden sensorineural hearing loss.

    Full Text Available BACKGROUND: Sudden sensorineural hearing loss (SSNHL is a perplexing condition for patients and there are many controversies about its etiology, audiologic characteristics, prognostic factors, and treatment. METHODS: In this prospective study, we performed some audiologic tests, including PTA, IA, ABR, and OAE (TEOAE before beginning treatment of 53 patients with SSNHL. We assigned the patients randomly to two treatment groups: oral steroids + acyclovir vs. intravenous urographin. Twenty-eight patients underwent Magnetic Resonance Imaging (MRI of the Brain. RESULTS: Of 53 patients (22 female and 31 male, 22 (41.5% had negative or no signal to noise ratio and overall correlation in TEOAE. Twenty-six patients (49% had positive overall correlations less than 50%, and 5 patients (4.4% had overall correlations >50%. Fifteen patients (28. 3% responded completely or well, 20 (37.7% responded partially, and 18 (33.9% had poor or no response to the treatment. The mean values for overall correlation in 3 subgroups of patients (no response, partial response, and complete response were – 3. 5% (+ 1/16%, +11% (+ 1/99%, and +36.6% (+3/07%, respectively (P = 0.01. Twenty out of 52 patients had no reproducible wave in ABR (38.5%, and waves I, III, and V were absent in 40 (77%, 31 (59.6% and 21 (40% patients, respectively. There were some limitations (false positive and false negative results in ABR use in our cases, but it may be useful in detecting site of lesion in SSNHL. Overall, according to the results of OAE, ABR, and brain MRI of these patients, 3 were affected by acoustic neurinomas, at least 1 had auditory neuropathy, and the site of lesion was cochlear in 6, and cochlear + retrocochlear in 13 patients. CONCLUSIONS: ABR has limitations for use in SSNHL and seems not to obviate the need for brain MRI, but may help in determining the site of lesions such as ischemia or neuropathy. Overall correlation (and S/N ratio in TEOAE is a valuable

    Full Text Available Abstract Background Aim of the present study was to evaluate the occurence of a round window membrane rupture and the effects of hearing restoration after exploratory tympanotomy and sealing of the round window (niche in patients with unilateral sudden deafness. Methods Retrospective analysis of patients’ charts in a tertiary referral center. Charts of 69 patients with sudden deafness followed by exploratory tympanotomy were retrospectively analyzed. Pure-tone audiometry data before and after tympanotomy were compared to determine the outcome of hearing recovery. The postoperative hearing test values were documented 3 weeks after tympanotomy. All surgical reports were reviewed with regard to the surgical technique performed and the intraoperative findings. Results 18.8% of the patients revealed a visible perilymphatic fistula in the round window niche. 89.8% of the patients reported no typical history for a round window membrane rupture. All patients were treated with an exploratory tympanotomy under local anesthesia and an intravenous corticosteroid treatment regimen. The majority of the surgeons used a fat plomb to cover the round window. Postoperative hearing was significantly improved compared to the preoperative hearing test data. No patient showed a worsened hearing curve after the treatment. Conclusion Most patients suffering from unilateral sudden deafness had no visible perilymphatic fistula. In our study population, the majority of patients reported no typical history of a pressure elevation in the inner ear. Exploratory tympanotomy is a safe procedure that may support hearing recovery in patients with sudden deafness in addition to the established treatment regimen including high-dose steroids.

    Case evidence is presented that highlights the clinical relevance and significance of a novel sound therapy-based treatment. This intervention has been shown to be efficacious in a randomized controlled trial for promoting expansion of the dynamic range for loudness and increased sound tolerance among persons with sensorineural hearing losses. Prior to treatment, these individuals were unable to use aided sound effectively because of their limited dynamic ranges. These promising treatment effects are shown in this article to be functionally significant, giving rise to improved speech understanding and enhanced hearing aid benefit and satisfaction, and, in turn, to enhanced quality of life posttreatment. These posttreatment sound therapy effects also are shown to be sustained, in whole or part, with aided environmental sound and to be dependent on specialized counseling to maximize treatment benefit. Importantly, the treatment appears to be efficacious for hearing-impaired persons with primary hyperacusis (i.e., abnormally reduced loudness discomfort levels [LDLs]) and for persons with loudness recruitment (i.e., LDLs within the typical range), which suggests the intervention should generalize across most individuals with reduced dynamic ranges owing to sensorineural hearing loss. An exception presented in this article is for a person describing the perceptual experience of pronounced loudness adaptation, which apparently rendered the sound therapy inaudible and ineffectual for this individual. Ultimately, these case examples showcase the enormous potential of a surprisingly simple sound therapy intervention, which has utility for virtually all audiologists to master and empower the adaptive plasticity of the auditory system to achieve remarkable treatment benefits for large numbers of individuals with sensorineural hearing losses.

    Idiopathic sudden sensorineural hearing loss is a rare disorder of unknown pathogenesis in which hearing is lost partially or totally. About 60 treatment modalities have been described. We aimed to compare the efficacy of hyperbaric oxygen, oral steroid, intratympanic steroid therapy and their combinations in idiopathic sudden sensorineural hearing loss patients. Files of patients who were followed up between 2004 and 2010 in our clinic were examined retrospectively. Patients were divided into four groups according to the therapy received: Oral steroid, oral steroid + hyperbaric oxygen, intratympanic steroid and hyperbaric oxygen. Treatment success was assessed by Siegel criteria and mean gains using pre-treatment and post-treatment audiograms. 217 patients and 219 ears were examined. The proportion of patients responding to therapy was the highest in the oral steroid + hyperbaric oxygen group with 86.88% (53/61) followed by the oral steroid group with 63.79% (37/58), the intratympanic steroid group with 46,51% (20/43) and the hyperbaric oxygen group with 43.85% (25/57). The proportion of patients who had complete recovery was the highest in the oral steroid + hyperbaric oxygen group with 42.6% (26/61) followed by the oral steroid group with 19.0% (11/58), the hyperbaric oxygen group with 17.5% (10/57) and the intratympanic steroid group with 11.6% (5/43). The oral steroid + hyperbaric oxygen group has the highest mean hearing gain among all groups (p sudden sensorineural hearing loss patients receiving oral steroid + hyperbaric oxygen combination therapy have a higher likelihood of recovery than patients receiving oral steroids, hyperbaric oxygen or intratympanic steroids alone.

    Imaging plays an important role in the evaluation of congenital sensorineural hearing loss. In children who are candidates for cochlear implantation surgery, it provides vital preoperative information about the inner ear, the vestibulocochlear nerve, and the brain. High-resolution computed tomography (CT) and magnetic resonance (MR) imaging provide excellent delineation of the intricate anatomy of the inner ear: CT depicts the minute details of osseous structures, and MR imaging allows visualization of the fluid-filled spaces and the vestibulocochlear nerve. Together, these complementary modalities can aid decision making about the best management strategy by facilitating the identification and characterization of inner ear malformations and any associated neurologic abnormalities. It is important that the radiologist be familiar with the key imaging features when interpreting CT and MR images obtained in this patient group. A broad spectrum of inner ear malformations have been described and linked to developmental insults at different stages of embryogenesis, and various systems have been proposed for classifying them. In this article, these malformations are described by using classification systems used by otolaryngologists for ease of interpretation. The relevant normal anatomy and development of the inner ear are briefly surveyed, standard imaging protocols for studying the inner ear are reviewed, and the imaging appearances of frequently observed inner ear malformations are described and illustrated. The impact of the identification of these malformations and commonly associated brain abnormalities on clinical management and prognosis also is discussed.

    Sudden sensorineural hearing loss (SSHL) may be a manifestation of systemic vascular involvement in systemic lupus erythematosus (SLE) and may have an important impact on the health of patients with SLE. To investigate the risk of developing SSHL in patients with SLE, we conducted a population-based, retrospective cohort study from the Taiwan National Health Insurance Research Database. A total of 7168 patients diagnosed with SLE and 35840 control subjects without SLE were selected from claims made from 2001 to 2006. The incidence of SSHL was assessed and determined at the end of 2010. The incidence of SSHL was 2.22-fold higher in the SLE group than in the non-SLE group (6.52 vs. 2.93 per 10000 person-years), with an adjusted hazard ratio (HR) of 2.253 (95% confidence interval, CI=1.407-3.608) calculated using a Cox proportional hazard regression model. Age was an independent risk factor for SSHL, with adjusted HRs of 2.103 for individuals aged≥35 years compared with those 0-34 years. In the 0-34 age range, the incidence of developing SSHL was 4.27-fold (95% CI=2.11-8.67) higher in the SLE group compared with the non-SLE group. In female patients, the incidence of developing SSHL was 2.19-fold (95% CI=1.73-3.50) higher in the SLE group than in the non-SLE group. Systemic lupus erythematosus was significantly associated with an increased risk of developing SSHL. Scheduled auditory examinations for patients with SLE to assess the presence of chronic hearing impairment are advised to enable the early detection of SSHL.

    The aim of this study was to examine the activities of hASCs (Human Adipose tissue Derived Stem Cells) on experimental autoimmune hearing loss (EAHL) and how human stem cells regenerated mouse cochlea cells. We have restored hearing in 19 years old white female with autoimmune hearing loss with autologous adipose tissue derived stem cells and we wish to understand the mechanism of restoration of hearing in animal model. BALB/c mice underwent to develop EAHL; mice with EAHL were given hASCs intraperitoneally once a week for 6 consecutive weeks. ABR were examined over time. The helper type 1 autoreactive responses and T-reg cells were examined. H&E staining or immunostaining with APC conjugated anti-HLA-ABC antibody were conducted. The organ of Corti, stria vascularis, spira ligament and spiral ganglion in stem cell group are normal. In control group, without receiving stem cells, the organ of Corti is replaced by a single layer of cells, atrophy of stria vascularis. Systemic infusion of hASCs significantly improved hearing function and protected hair cells in established EAHL. The hASCs decreased the proliferation of antigen specific Th1/Th17 cells and induced the production of anti-inflammatory cytokine interleukin10 in splenocytes. They also induced the generation of antigen specific CD4(+)CD25(+)Foxp3(+)T-reg cells. The experiment showed the restoration is due to the paracrine activities of human stem cells, since there are newly regenerated mice spiral ganglion cells, not human mesenchymal stem cells derived tissue given by intraperitoneally.

    Along with sudden sensorineural hearing loss, hearing usually declines without any reason, which affects the patients′ work and life severely, and causes psychological problems like anxiety, fear, and many others. Because pathogenesis and pathomechanism of sudden sensorineural hearing loss are not yet clear according to domestic and overseas researches, there are not targeted therapies. Effective nursing intervention and health care guides can facilitate the patients with cognition of this disease, and then help them participate in the treatment positively and regain their hearing.%突发性感音神经性耳聋发作时听力常在无诱因的情况下突然下降,严重影响患者的工作生活,同时继发焦虑、恐惧等心理问题。由于国内外对突聋的病因及病理机制尚未明确,目前尚无针对性的治疗方法。有效的护理干预和保健指导工作,可以提高患者对突聋的认知程度,有助于其积极配合治疗以促进听力恢复。

    Full Text Available Background and Aim: Sudden Sensorineural Hearing Loss (SSNHL is an emergency situation, and is one of the most controversial subjects in domain of otolaryngology. In this article, we have analyzed some Epidemiologic Characteristics, clinical features, audiological Characteristics, and other findings in routine serological tests and MRI of 48 cases with SSNHL ,who came or were referred to us in the past 2 years. Study design: Cross sectional. Materials and Methods: In 48 patients with chief complaint of SSNHL, from June 2003 to Feb. 2005, who were admitted in clinic of otolaryngology- in Kashani Hospital -Isfahan- Iran, physical examination and history taking, audiological evaluation, MRI,and serological tests were performed in a similar way , and data were analyzed by SPSS software. Results: From 48 cases(M:28 ,F:20 with mean age of 40.9(+/-15.9 years, left ear was involved in 26 cases (54.1% ,and right ear in 19 cases (39.5% ,and in 3 cases (6.3%,both sides were involved. The severity of hearing loss was “subjectively” HIGH in 78% of patients, and the mean threshold of hearing had been calculated as 69 dB. The most common pattern in pure tone audiometry curves ,was ‘flat pattern’(75% ,and then ,’down sloping pattern’(16%.The most adjunctive clinical symptom was “tinnitus”(in 78.7%, and 40% of patients had “true vertigo”. 44.4% of our patients had some evidences of upper respiratory tract infections (URIs during recent 2 weeks.

    Hearing loss may be genetic, associated with aging or exposure to noise or ototoxic substances. Its aetiology can be attributed to vascular injury, trauma, tumours, infections or autoimmune response. All these factors could be related to alterations in cochlear microcirculation resulting in hypoxia, which in turn may damage cochlear hair cells and neurons, leading to deafness. Hypoxia could underlie the aetiology of deafness, but very few data about it are presently available. The aim of this work is to develop animal models of hypoxia and ischemia suitable for study of cochlear vascular damage, characterizing them by electrophysiology and gene/protein expression analyses. The effects of hypoxia in infarction were mimicked in rat by partial permanent occlusion of the left coronary artery, and those of ischemia in thrombosis by complete temporary carotid occlusion. In our models both hypoxia and ischemia caused a small but significant hearing loss, localized at the cochlear apex. A slight induction of the coagulation cascade and of oxidative stress pathways was detected as cell survival mechanism, and cell damages were found on the cuticular plate of outer hair cells only after carotid ischemia. Based on these data, the two developed models appear suitable for in vivo studies of cochlear vascular damage.

    Poststroke sudden sensorineural hearing loss (SSNHL) can hinder communication between patients and healthcare professionals, thereby restricting participation in rehabilitation programs and limiting improvements in physical performance. However, the relationship between stroke and SSNHL remains unclear. This study employed a nationwide population-based dataset to investigate the relationship between stroke and SSNHL.The Taiwan Longitudinal Health Insurance Database was used to compile data from 11,115 stroke patients and a comparison cohort of 33,345 matched nonstroke enrollees. Each patient was followed for 5 years to identify new-onset SSNHL. Stratified Cox proportional-hazard regression analysis was used to examine the association of stroke with subsequent SSNHL.Among the 44,460 patients, 66 patients (55,378 person-years) from the stroke cohort and 105 patients (166,586 person-years) from the comparison cohort were diagnosed with SSNHL. The incidence of SSNHL was approximately twice as high among stroke patients than among nonstroke patients (1.19 and 0.63/1000 person-years, respectively). Stroke patients had a 71% increased risk of SSNHL, compared with nonstroke patients (adjusted hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.24-2.36). We also observed a remarkable increase in risk of SSNHL in stroke patients within 1-year of follow-up (adjusted HR 5.65, 95% CI 3.07-10.41) or under steroid therapy during hospitalization (adjusted HR 5.14, 95% CI 2.08-12.75).Patients with stroke had a higher risk of subsequent SSNHL compared with patients without stroke. In particular, stroke patients within 1-year follow-up and those undergoing steroid therapy during hospitalization should be treated with the utmost caution, considering that the risk of SSNHL increases by more than 5-fold.

    Full Text Available Introduction: Sudden sensorineural hearing loss (SSNHL is a true emergency that must be diagnosed and treated immediately. The purpose of this study is to compare the efficacy of treatment with intratympanic dexamethasone plus oral prednisolone daily or every other day with that of treatment with oral prednisolone alone. Materials and Methods: Sixty-three patients with SSNHL that had been present for less than 10 days prior to the start of treatment were randomly allocated to three different groups. Patients in group A were treated daily with oral prednisolone 1 mg/kg for 10 days plus intratympanic dexamethasone 2 mg for the first 3 days of treatment. Patients in group B were treated every other day with oral prednisolone 1 mg/kg for 10 days with the addition of intratympanic dexamethasone 2 mg for the first 3 treatments. Patients in group C were treated daily with oral prednisolone 1 mg/kg alone for 10 days. Audiometric parameters including pure tone audiometry (PTA, speech reception threshold (SRT, and speech discrimination score (SDS were assessed on days 1,5, and 10. Results: There was a significant improvement in PTA, SRT and SDS in each group over the 10 days but the greatest improvement was seen in the SRT measurements of group A in comparison with group B (19.81 ± 2.15, P=0.04 and C (26.26 ± 0.08, P=0.01. The difference in SRT between groups B and C was not statistically significant. Conclusion: The administration of intratympanic dexamethasone 2 mg daily for 3 days has an additive effect to that of 10 days of oral prednisolone 1 mg/kg in the treatment of SSNHL.

    Cochlear implantation (CI) is an established technique for enabling speech perception in patients suffering from severe bilateral sensorineural hearing loss (SNHL). Thorough preoperative radiological assessment is essential for correctly evaluating the indication for surgery and safely performing cochlear implantation. CT and conventional and functional MRI are available for radiological assessment. Therefore, knowledge of the most frequent congenital syndromal, non-syndromal, and acquired malformations of inner ear structures is fundamental. This article provides information about imaging techniques prior to CI and relevant malformations of the inner ear. Safety aspects for patients with a cochlear implant undergoing MR imaging are also discussed. (orig.)

    Full Text Available Acupuncture has commonly been used in China, either alone or in combination with Western medicine, to treat sudden sensorineural hearing loss (SSHL. The purpose of this systematic review is to assess the efficacy and safety of acupuncture therapy for patients with SSHL.We searched PubMed, the Cochrane Library, Embase, China National Knowledge Internet (CNKI, Database for Chinese Technical Periodicals (VIP, and Chinese Biomedical literature service system (SinoMed to collect randomized controlled trials of acupuncture for SSHL published before July 2014. A meta-analysis was conducted according to the Cochrane systematic review method using RevMan 5.2 software. The evidence level for each outcome was assessed using the GRADE methodology.Twelve trials involving 863 patients were included. A meta-analysis showed that the effect of manual acupuncture combined with Western medicine comprehensive treatment (WMCT was better than WMCT alone (RR 1.33, 95%CI 1.19-1.49 and the same as the effect of electroacupuncture combined with WMCT (RR 1.33, 95%CI 1.19-1.50. One study showed a better effect of electroacupuncture than of WMCT (RR 1.34, 95%CI 1.24-1.45. For mean changes in hearing over all frequencies, the meta-analysis showed a better effect with the combination of acupuncture and WMCT than with WMCT alone (MD 10.85, 95%CI 6.84-14.86. However, the evidence levels for these interventions were low or very low due to a high risk of bias and small sample sizes in the included studies.There was not sufficient evidence showing that acupuncture therapy alone was beneficial for treating SSHL. However, interventions combining acupuncture with WMCT had more efficacious results in the treatment of SSHL than WMCT alone. Electroacupuncture alone might be a viable alternative treatment besides WMCT for SSHL. However, given that there were fewer eligible RCTs and limitations in the included trials, such as methodological drawbacks and small sample sizes, large

    Full Text Available Abstract The aim was to study the frequencies of common deafness-related mutations and their contribution to hearing loss in different regions of Inner Mongolia. A total of 738 deaf children were recruited from five different ethnic groups of Inner Mongolia, including Han Chinese (n=486, Mongolian (n=216, Manchurian (n=24, Hui (n=6 and Daur (n=6. Nine common mutations in four genes (GJB2, SLC26A4, GJB3 and mitochondrial MT-RNR1 gene were detected by allele-specific PCR and universal array. At least one mutated allele was detected in 282 patients. Pathogenic mutations were detected in 168 patients: 114 were homozygotes and 54 were compound heterozygotes. The 114 patients were carriers of only one mutated allele. The frequency of GJB2 variants in Han Chinese (21.0% was higher than that in Mongolians (16.7%, but not significantly different. On the other hand, the frequency of SLC26A4 variants in Han Chinese (14.8% was lower than that in Mongolians (19.4%, but also not significantly different. The frequency of patients with pathogenic mutations was different in Ulanqab (21.4%, Xilingol (40.0%, Chifeng (40.0%, Hulunbeier (30.0%, Hohhot (26.3%, and in Baotou (0%. In conclusion, the frequency of mutated alleles in deafness-related genes did not differ between Han Chinese and Mongolians. However, differences in the distribution of common deafness-related mutations were found among the investigated areas of Inner Mongolia.

    Full Text Available INTRODUÇÃO: O Lúpus Eritematoso Sistêmico (LES é uma doença sistêmica do tecido conectivo, de etiologia desconhecida, provavelmente multifatorial. Acomete principalmente o sexo feminino podendo afetar múltiplos órgãos, dentre eles o sistema auditivo. A orelha interna pode ser lesada por diversos mecanismos auto-imunes, sendo a manifestação mais freqüente a disacusia sensorioneural flutuante, geralmente bilateral, rapidamente progressiva e com boa responsividade a imunossupressores. OBJETIVO: O objetivo deste trabalho é relatar três casos de disacusia de etiologia auto-imune, enfocando formas de acometimento e manifestações clínicas, bem como correlacionando o efeito ototóxico da cloroquina - droga empregada no controle do LES - com a perda auditiva. CONCLUSÃO: As perdas auditivas sensorioneurais súbitas, rapidamente progressivas ou flutuantes, podem ocorrer em pacientes com doença auto-imune e devem ser sempre lembradas nos casos de disacusia sem causa aparente.INTRODUCTION: The Systemic Lupus Erythematosus (SLE is a systemic disease of the connective tissue, with unknown etiology, probably associated to multiple events. It is a multiple organs disease that affects mainly women. The inner ear can be damaged by several immunopathogenic mechanisms, and the most common symptom is a progressive sensorineural hearing loss, generally bilateral, with good response to immunossupression. AIM: The purpose of this article is to report three cases of women suffering from SLE and hearing loss and to establish a link between the autoimmune and the vascular mechanisms of the disease, also focusing attention on the ototoxicity due to chloroquine applied during the treatment of SLE. CONCLUSION: Sudden or fluctuant sensorineural hearing loss may affect patients with autoimmune disease, so it must always be taken into account when dealing with patients suffering from hearing loss without any apparent cause.

    The objective of this study was to determine the effectiveness, dosage, safety and comfort of intratympanic steroids as primary initial treatment of idiopathic sudden sensorineural hearing loss (ISSHL). Prospective nonrandomized clinical practice study was performed in Tertiary referral center university hospital. A total of 35 consecutive patients suffering from newly diagnosed sudden sensorineural hearing loss with mean pure-tone average thresholds of 81 ± 21 dB were treated. No previous therapy had been undertaken. Intratympanic steroid injection as primary initial treatment was administered during 2 weeks on a twice a week schedule, between 2010 and 2011. Treatment was started on average within 2 days of symptoms onset. Pre and post-treatment audiometric evaluations were analyzed on follow-up as well as tolerance of the procedure and possible adverse effects. 66-85 % of patients achieved successful treatment according to the different outcome criteria used to evaluate hearing improvement (Furuhashi criteria/improvement of ≥10 dB in pure-tone average). Mean post-treatment improvement regarding pure-tone average was 34 ± 21 dB. A 48 ± 43 % improvement in speech discrimination score was observed. Patients received an average of 18 mg of methylprednisolone per injection and a total dose of 72 mg per treatment cycle. No serious adverse effects were noted. Intratympanic steroid injection is an effective, safe and well-tolerated office based-procedure for the treatment of ISSHL as primary initial treatment that can avoid the potential adverse effects of systemic steroids. A higher dose, schedule of administration as well as standardization of hearing recovery criteria still need to be established.

    To establish an animal model of sudden onset sensorineural hearing loss (SSNHL) to study its mechanisms. Materials and methods The inner ear was exposed to 3-nitropropionic acid at 0.5 mol/L (3-NP (H)) and 0.3 mol/L (3-NP (L)) through the round window membrane for 30 minutes in 50 male guinea pigs. Thresholds of auditory brainstem responses (ABR) were established before the treatment and retested at 4 hours, 1 day, 3 days and 6 days following 3-NP exposure. Control animals were treated with phosphate buffered saline (PBS) and their ABRs were retested at 4 hours and 1 day after the treatment. Animals were monitored for nystagmus and postural signs of vestibular dysfunction, using a digital video camera, following the treatment procedure. Specimens were taken at 12 hours, 1 day, 3 days and 7 days following 3-NP (H) exposure and embedded in JB4 for light microscopy observation. Results ABRs were lost in all animals tested at 4 hours following 3-NP (H) exposure. The rate of complete ABR loss decreased as post-treatment test time increased. ABRs were lost in 80% (4/5) of the animals at 1 day after exposure to 3-NP (L). Spontaneous horizontal nystagmus with a fast phase away from the treated ear developed in all 3-NP (H)-treated animals and in 20 % (1/5) of the animals exposed to 3-NP (L), except for the one treated bilaterally. Various degree of postural disturbances consistent with unilateral vestibular dysfunction, such as spontaneous barrel rolling towards the exposure side while walking, were seen in all animals exposed to 3-NP(H) and 40% (2/5) of animals exposed to 3-NP(L), except for the one animal treated bilaterally, which showed no signs of imbalance. Both nystagmus and postural disturbances resolved in 2 days following 3-NP exposure. Histological study showed temporary edema tin the organ or Corti, Claudius cells and the inner sulcus cells 3 days after 3-NP (H) treatment. Enlargement of intercellular space in the spiral prominence was first noticed at 12 hours

    Full Text Available Introduction: Hearing loss is a frequent problem in childhood with an incidence of about one case per 1000 births. Control of deafness should be aimed at prevention and early diagnosis in efforts to provide appropriate treatment and stimulate adequate communication in children affected. The objective of this study was to determine the prevalence of different etiologies among deaf children with a diagnosis of prelingual sensorineural hearing loss referred to the Fundación CINDA in Bogotá, Colombia, between 1997 and 2008.Materials and methods: The medical records were selected from those with prelingual hearing loss. Information was gathered in a format containing variables related to the risk factors suggested by the Joint Committee of Infant Hearing.Results: We studied 254 children; boys and girls were equally distributed. The most common etiological diagnosis was «unknown cause», followed by genetic causes (31 cases, and 38 cases from TORCH infections (toxoplasmosis, others – syphilis, rubella, cytomegalovirus, herpes, with rubella as the most common cause.Conclusions: Review of prenatal, perinatal, and postnatal history often reveals the cause of the deafness in children; therefore, appropriate evaluation of pregnant mothers could result in decreased frequency of deafness in children in our country.

    Full Text Available Abstract Background Sudden sensorineural hearing loss (SSHL is a common condition in which patients lose the hearing in one ear within 3 days. Systemic glucocorticoid treatments have been used as standard therapy for SSHL; however, about 20% of patients do not respond. We tested the safety and efficacy of topical insulin-like growth factor 1 (IGF1 application using gelatin hydrogels as a treatment for SSHL. Methods Patients with SSHL that showed no recovery to systemic glucocorticoid administration were recruited. We applied gelatin hydrogels, impregnated with recombinant human IGF1, into the middle ear. The primary outcome measure was the proportion of patients showing hearing improvement 12 weeks after the test treatment. The secondary outcome measures were the proportion of patients showing improvement at 24 weeks and the incidence of adverse events. The null hypothesis was that 33% of patients would show hearing improvement, as was reported for a historical control after hyperbaric oxygen therapy. Results In total, 25 patients received the test treatment at a median of 23 days (range 15-32 after the onset of SSHL, between 2007 and 2009. At 12 weeks after the test treatment, 48% (95% CI 28% to 69%; P = 0.086 of patients showed hearing improvement, and the proportion increased to 56% (95% CI 35% to 76%; P = 0.015 at 24 weeks. No serious adverse events were observed. Conclusions Topical IGF1 application using gelatin hydrogels is well tolerated and may be efficacious for hearing recovery in patients with SSHL that is resistant to systemic glucocorticoids.

    The etiology of benign paroxysmal positional vertigo (BPPV) is still elusive even though detached otolith particles from the utricular macula are generally thought to be responsible for the pathogenesis of BPPV. Sudden sensorineural hearing loss (SSNHL), of which the etiology is also idiopathic in most cases, may accompany concurrent BPPV. This uncommon condition of concurrent BPPV with SSNHL has been assumptively explained as selective damage of the cochlea and the utricle due to viral neurolabyrinthitis. Recently, radiological evidences that inner ear hemorrhage is observed in patients with SSNHL accompanied by severe vertigo have been reported. The basic hypothesis for this study is that blood debris in the endolymphatic fluid due to inner ear hemorrhage is one of the causes of concurrent posterior semicircular canal (PSCC) BPPV in patient with ipsilateral SSNHL. In this report, we will outline the clinical findings of 4 patients with PSCC BPPV with SSNHL, and present an experimental results using whole blood in artificial endolymph to evaluate the hypothesis.

    Background: Inner ear malformations may cause sensorineural hearing loss (SNHL). However, the correlation between the small lateral semi-circular canal (LSCC) and SNHL is controversial. Purpose: To determine whether there is a correlation between the two using CT-based measurement. Material and Methods: We retrospectively reviewed the high-resolution CT images of the temporal bone obtained from consecutive patients. A total 136 ears of 68 patients (25 men and 43 women; age range 20-85 years, mean 49.8 years) were included in this study. Patients who were clinically suspected to have otosclerosis were also excluded. Two radiologists independently measured the width and cross-sectional area of the bony island of LSCC. We evaluated the correlation between LSCC bone island width or cross-sectional area and hearing level in all cases using Pearson correlation co-efficients. In addition, we compared hearing levels among the patient group with normal-sized LSCC (>=mean-SD), small LSCC (hearing level (P>0.05). No significant difference in hearing levels were found among groups of the normal-sized, small and very small LSCC (P>0.05). Conclusion: We conclude that there is no correlation between isolated small LSCC and SNHL

    Introduced in the late 90s, the active middle ear implant Vibrant Soundbridge (VSB) is nowadays used for hearing rehabilitation in patients with mild to severe sensorineural hearing loss (SNHL) unable to tolerate conventional hearing aids. In experienced hands, the surgical implantation is fast done, safe and highly standardized. Here, we present a systematic review, after more than 15 years of application, to determine the efficacy/effectiveness and cost-effectiveness, as well as patient satisfaction with the VSB active middle ear implant in the treatment of mild to severe SNHL. A systematic search of electronic databases, investigating the safety and effectiveness of the VSB in SNHL plus medical condition resulted in a total of 1640 papers. After removing duplicates, unrelated articles, screening against inclusion criteria and after in-depth screening, the number decreased to 37 articles. 13 articles were further excluded due to insufficient outcome data. 24 studies remained to be systematically reviewed. Data was searched on safety, efficacy and economical outcomes with the VSB. Safety-oriented outcomes included complication/adverse event rates, damage to the middle/inner ear, revision surgery/explant rate/device failure and mortality. Efficacy outcomes were divided into audiological outcomes, including hearing thresholds, functional gain, speech perception in quiet and noise, speech recognition thresholds, real ear insertion gain and subjective outcomes determined by questionnaires and patient-oriented scales. Data related to quality of life (QALY, ICER) were considered under economical outcomes. The VSB turns out to be a highly reliable and a safe device which significantly improves perception of speech in noisy situations with a high sound quality. In addition, the subjective benefit of the VSB was found to be mostly significant in all studies. Finally, implantation with the VSB proved to be a cost-effective and justified health care intervention.

    感音神经性耳聋是临床常见问题,若不能及时发现和正确干预,可导致儿童听觉言语发育迟缓,以及情感、心理和社会交往等综合能力的发展。新生儿听力筛查与新生儿基因筛查使得感音神经性耳聋的早期发现成为可能。儿童期的听力筛查工作很大程度上弥补了因迟发性、渐进性或获得性听力损失导致的新生儿听力筛查漏诊的不足。感音神经性耳聋通过主客观听力检测技术可获得早期诊断,通过药物治疗、选配助听装置等获得早期干预。永久性感音神经性听力损失作为一种慢性疾病,传统的以医生为中心的医疗服务模式不足以满足患者需求,以患者、家庭或社区为中心的医疗服务模式逐渐被重视。%Sensorineural hearing loss (SNHL) is commonly seen in clinical practice. Without early detection and appropriate intervention, it may cause delayed hearing and speech development and relevant emotional, psychological and social communication problems in children. The universal newborn hearing screening (UNHS) program and newborn genetic screening for deafness makes it possible to detect the SNHL in the early stage, while the hearing screening program for children can identify the children with delayed-onset, progressive or acquired hearing loss. SNHL can be early diagnosed using both subjective and objective hearing tests, and early intervened with medicine, hearing devices and other methods. As a chronic disease, SNHL patients may not be satisfied by the traditional clinician-centered medical service model, so the patient-centered, family-centered and community-centered models are gradually encouraged in recent years.

    Full Text Available Bone marrow mesenchymal stem cells (BMSCs expressing recombinant IL-4 have the potential to remediate inflammatory diseases. We thus investigated whether BMSCs expressing exogenous IL-4 could alleviate autoimmune sensorineural hearing loss. BMSCs isolated from guinea pigs were transfected with recombinant lentivirus expressing IL-4. A total of 33 animals were divided into three groups. Group A received scala tympani injection of IL-4-expressing BMSCs, and Group B received control vector-expressing BMSCs, and Group C received phosphate-buffered saline. The distribution of implanted BMSCs in the inner ears was assessed by immunohistochemistry and fluorescence microscopy. Auditory brain-stem response (ABR was monitored to evaluate the auditory changes. Following BMSCs transplantation, the threshold levels of ABR wave III decreased in Groups A and B and significant differences were observed between these two groups P<0.05. Transplanted BMSCs distributed in the scala tympani and scala vestibuli. In some ears with hearing loss, there was a decrease in the number of spiral ganglion cells and varying degrees of endolymphatic hydrops or floccule. Following transplantation, the lentivirus-infected BMSCs migrated to the inner ear and produced IL-4. Our results demonstrate that, upon transplantation, BMSCs and BMSCs expressing recombinant IL-4 have the ability to remediate the inflammatory injury in autoimmune inner ear diseases.

    Full Text Available Background. We aim to provide useful evidence about the association of neutrophil-to-lymphocyte ratio (NLR and platelet-to-lymphocyte ratio (PLR with idiopathic sudden sensorineural hearing loss (ISSNHL and its possibility of emerging as a cheap, reliable, and independent prognostic marker of ISSNHL. Methods. 348 patients diagnosed with ISSNHL were included in our retrospective data analysis. Blood samples and the hearing assessments of the patients were carried out. Then, the patients were divided into 2 groups as “recovered” and “unrecovered” according to their response to the treatment. Results. Both mean NLR and PLR values of the ISSNHL patients were significantly higher than the control group (both P<0.001. The NLR value was 5.98±4.22 in the unrecovered group and 3.50±3.38 in the recovered group (P<0.001. After adjustment in a binary logistic regression model, only NLR value was associated with the recovery of ISSNHL (P=0.001. Discussion. We demonstrated for the first time that NLR and PLR values were significantly high in ISSNHL patients. Also the NLR level might be taken into account as a novel potential marker to predict the patients’ prognosis in terms of recovery.

    Sudden sensorineural hearing loss is usually unilateral, and the cause is not identified in most adult cases. However, a specific cause has frequently been found in the case of children, in whom idiopathic sudden sensorineural hearing loss (ISHL) is comparatively rare. We investigated 20 cases of acute unilateral sensorineural hearing loss in children associated with a certain disease, but which was first diagnosed as ISHL. Thirteen patients aged 6 to 16 years old were diagnosed as having psychogenic (functional) hearing loss. Discrepancies in behavioral and objective tests are most valuable when functional hearing loss is suspected. Elevated pure-tone thresholds associated with normal distortion product otoacoustic emissions (DPOAEs) enable prompt further investigation. There are several conditions that may mimic functional hearing loss, so auditory brainstem response (ABR) testing is necessary to verify the actual cause. The unilateral profound hearing loss in 2 patients aged 7 and 11 years old was due to asymptomatic mumps proven by detecting the mumps IgM antibody. Total hearing recovery in the 125-1000 Hz frequencies occurred in one case. In 5 patients aged 6 to 12 years old with acute hearing loss and vertigo, high resolution CT imaging showed an abnormally enlarged vestibular aqueduct on the affected side. Large vestibular aqueduct syndrome should be considered in acute high-frequency sloping hearing loss with an A-B gap at low frequencies.

    Hearing loss has been reported with valproic acid (VPA) use. However, this is the first case of VPA-induced hearing loss that was tested and confirmed with a VPA rechallenge, supported by serial audiometry and pharmacokinetic modelling. A 39-year-old truck driver with temporal lobe epilepsy was treated with VPA at 400 mg, twice daily, and developed hearing loss after each dose, but recovered within three hours. Hearing loss fully resolved after VPA discontinuation. Audiometry performed five hours after VPA rechallenge showed significant improvement in hearing thresholds. Pharmacokinetic modelling during the VPA rechallenge showed that hearing loss occurred at a level below the therapeutic range. Brainstem auditory evoked potential at three months after VPA discontinuation showed bilateral conduction defect between the cochlear and superior olivary nucleus, supporting a pre-existing auditory deficit. VPA may cause temporary hearing threshold shift. Pre-existing auditory defect may be a risk factor for VPA-induced hearing loss. Caution should be taken while prescribing VPA to patients with pre-existing auditory deficit.

    The primary aim of this research was to evaluate the validity, efficacy, and generalization of principles underlying a sound therapy–based treatment for promoting expansion of the auditory dynamic range (DR) for loudness. The basic sound therapy principles, originally devised for treatment of hyperacusis among patients with tinnitus, were evaluated in this study in a target sample of unsuccessfully fit and/or problematic prospective hearing aid users with diminished DRs (owing to their elevated audiometric thresholds and reduced sound tolerance). Secondary aims included: (1) delineation of the treatment contributions from the counseling and sound therapy components to the full-treatment protocol and, in turn, the isolated treatment effects from each of these individual components to intervention success; and (2) characterization of the respective dynamics for full, partial, and control treatments. Thirty-six participants with bilateral sensorineural hearing losses and reduced DRs, which affected their actual or perceived ability to use hearing aids, were enrolled in and completed a placebo-controlled (for sound therapy) randomized clinical trial. The 2 × 2 factorial trial design was implemented with or without various assignments of counseling and sound therapy. Specifically, participants were assigned randomly to one of four treatment groups (nine participants per group), including: (1) group 1—full treatment achieved with scripted counseling plus sound therapy implemented with binaural sound generators; (2) group 2—partial treatment achieved with counseling and placebo sound generators (PSGs); (3) group 3—partial treatment achieved with binaural sound generators alone; and (4) group 4—a neutral control treatment implemented with the PSGs alone. Repeated measurements of categorical loudness judgments served as the primary outcome measure. The full-treatment categorical-loudness judgments for group 1, measured at treatment termination, were

    Full Text Available Abstract Background The 5 G/5 G genotype of PAI-1 polymorphism is linked to decreased plasminogen activator inhibitor-1 (PAI-1 levels and it has been suggested that lower PAI-1 levels may provide protective effects on inflammation, local microcirculatory disturbance, and fibrotic changes, which are likely associated with development of sudden sensorineural hearing loss (SSNHL. Methods The association of the 4 G/5 G PAI-1 polymorphism with the development and clinical outcome of SSNHL is evaluated via a case control study. 103 patients with SSNHL and 113 age and sex-matched controls were enrolled at University of Ferrara, Italy and hearing loss outcome was measured at least 3 months after the onset of hearing loss. DNA was isolated from peripheral blood using the QIAamp kit and the 4 G/5 G polymorphism in the −675 promoter region was genotyped with an allele-specific PCR. Genotype distribution was tested in patients and compared to controls by chi-square and odd-ratio analysis. The codominant and recessive models were used for the multiple logistic regression analyses of the PAI-1 gene allele. Results In this population, 5 G/5 G genotype had a two-time lower frequency in SSNHL patients compared to healthy controls (15.5% vs 30.1% and was associated with decreased odds compared to 4 G/5 G genotype (OR 0.37, 95% CI 0.19-0.75, p = 0.005. In addition, the patients with 5 G/5 G genotype showed a trend of more than 2 times higher ratio of hearing recovery (> 20 dB after systemic corticosteroid treatment compared to 4 G/5 G genotype (OR 2.3, 95% CI 0.32 - 16.83, p = 0.39, suggesting a better clinical outcome. Conclusions The 5 G/5 G genotype of PAI-1 may be associated with a reduced risk of SSNHL in the Italian population.

    Epidemiological studies have reported inconsistent findings on the association between the V Leiden G1691A mutation and sudden sensorineural hearing loss (SSNHL) in Italian population. The aim of this meta-analysis was to clarify this association. PubMed, Embase, and the China National Knowledge Infrastructure (CNKI) were searched up to April 1, 2015. We used STATA12.0 to calculate summary odds ratios (ORs) with 95 % confidence intervals (CIs). Four studies including 958 patients were identified. Pooled data showed no significant association between V Leiden G1691A mutation and risk of SSNHL in Italian population: A vs. G (OR = 1.660, 95 % CI 0.428-6.446, P OR = 0.464) and AG vs. GG (OR = 1.680, 95 % CI 0.422-6.688, P OR = 0.462). The present meta-analysis suggests that V Leiden G1691A mutation is not significantly associated with increased risk of SSNHL disease in Italian population. Further large and well-designed studies are needed to confirm this association.

Material and Methods: MR IE studies of 158 consecutive patients (316 IEs) suffering from sensorineural hearing loss without evidence of an acoustic neurinoma were reviewed for pathologies of the IE and internal acoustic meatus. High-resolution MR data of all abnormal IE studies (n=45) were post-processed to previously standardized 3D volume rendered (VR) reconstructions. Results: In 9 patients (5.7%) the following IE dysplasias were detected: malformation of the cochlea (6 IEs), vestibulum (4 IEs), semicircular canals (12 IEs) and vestibular aqueduct/endolymphatic sac (10 IEs). One patient showed evidence of an aplasia of the vestibulocochlear nerve. In 4 patients multiple IE dysplasias were encountered. Comprehensive 3D visualization of all labyrinthine dysplasias was achieved by the use of two VR reconstructions. The overall time for bilateral IE assessment amounted to 30-35 min. Conclusion: The imaging protocol allows for rapid and comprehensive visualization of various IE dysplasias, based on a limited number of VR reconstructions.

    Objective:To investigate immune-related genetic background in bilateral sudden sensorineural hearing loss (SSNHL). Case report and methods: The case is a 45-year-old man presenting with a 7-year history of bilateral profound SSNHL. Blood biochemical testing demonstrated increased levels of total cholesterol (5.88 mmol/L). Tests for hepatitis B showed a positive antibody against the hepatitis B core antigen. Complement C3 was below the normal value, and complement C4 and IgG were in the lower range of normal values. CT images showed a normal inner ear and vestibular aqueduct but round window membranous ossification on both sides. A total number of 232 immune-associated genes were sequenced using the next generation sequencing technique. Results: Mutations were detected in 5 genes, including the phosphoinositide 3-kinase catalytic subunit delta (PIK3CD), caspase recruitment domain-containing protein 9 (CARD9), complement factor H-related (CFHR2), immunoglobulin lambda-like polypeptide 1 Protein (IGLL1), and transmembrane channel-like gene family 8 (TMC8). In the PIK3CD gene, a C896T substitute in exon 7 was detected. This mutation causes primary immunodeficiency and is an autosomal dominant disease. Conclusion: The PIK3CD C896T mutation responsible for primary immunodeficiency may contribute to the onset of bilateral SSNHL with subsequent rapid progression.

    Steroids are currently the most frequently accepted agents for idiopathic sudden sensorineural hearing loss (ISSNHL). However, the therapeutic effect of steroids is not always satisfactory. In this pilot study, we evaluated whether systemic treatment with Ginkgo biloba extract (EGb761) has an additive therapeutic effect in patients receiving a systemic steroid due to ISSNHL. A multicenter, randomized, double-blind clinical trial was performed. Fifty-six patients with ISSNHL were allocated to either EGb761 or placebo. In both groups, methylprednisolone was administered for 14 days. EGb761 was infused intravenously for 5 days in the EGb761 group, while the same amount of normal saline was infused in the placebo group. For the efficacy evaluation, pure-tone audiometry, speech audiometry, tinnitus handicap inventory (THI) and short form-36 health (SF-36) survey outcomes were obtained before administration and on days 3, 5, 14 and 28 of administration. Twenty-four patients in each group completed the study protocol. There was no difference in hearing loss between the two groups before treatment. At day 28, air conduction threshold values in the placebo and EGb761 groups were 34.63 ± 28.90 and 23.84 ± 25.42 dB, respectively (p = 0.082). Speech discrimination scores in the placebo and EGb761 groups were 69.17 ± 40.89 and 87.48 ± 28.65 %, respectively (p = 0.050). THI and SF-36 scores in the placebo and EGb761 groups were similar. Although a combination of steroid and EGb761 for initial treatment did not show better pure tone threshold, compared with steroid alone, speech discrimination was significantly improved in combination therapy. Further studies will be needed to know if addition of EGb761 actually improves the outcome of ISSNHL treatment.

    The aim of this prospective single-blind randomized controlled study was to evaluate the therapeutic efficacy of high dose intravenous vitamin C (HDVC) added to systemic steroid in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Between August 2010 and August 2011, 72 ISSNHL patients who participated in this study were randomly allocated to two groups: 36 to a control group, members of which were given systemic steroid treatment for 15 days, and 36 to a HDVC group, members of which were given HDVC (200 mg/kg/day) for 10 days in addition to steroid therapy followed by oral vitamin C (2,000 mg) for 30 days after discharge. Finally, we analyzed each group: 35 as a control group and 32 as a HDVC group. Auditory evaluations were performed by pure tone audiometry (PTA) before and ~1 month after treatment using Siegel's criteria. HDVC group showed significantly greater complete and partial recovery improvement (p = 0.035). In addition, the complete recovery rate in the HDVC group was more than twice that of the control group (p = 0.031). In the HDVC group, PTA improved from 67.6 ± 19.8 dB HL before treatment to 37.1 ± 28.8 dB HL at 1 month after treatment, whereas in the control group, PTA improved from 70.3 ± 12.4 to 47.6 ± 25.2 dB HL, which represented a significant intergroup difference (p = 0.030). In conclusion, HDVC may enhance hearing recovery in ISSNHL patients, which suggests that HDVC reduces levels of reactive oxygen metabolites produced by inner ear ischemia or inflammation, and that HDVC could be considered for the treatment of ISSNHL.

    Full Text Available This study describes a new noise suppression scheme for hearing aid applications based on the auditory masking threshold (AMT in conjunction with a modified generalized minimum mean square error estimator (GMMSE for individual subjects with hearing loss. The representation of cochlear frequency resolution is achieved in terms of auditory filter equivalent rectangular bandwidths (ERBs. Estimation of AMT and spreading functions for masking are implemented in two ways: with normal auditory thresholds and normal auditory filter bandwidths (GMMSE-AMT[ERB]-NH and with elevated thresholds and broader auditory filters characteristic of cochlear hearing loss (GMMSE-AMT[ERB]-HI. Evaluation is performed using speech corpora with objective quality measures (segmental SNR, Itakura-Saito, along with formal listener evaluations of speech quality rating and intelligibility. While no measurable changes in intelligibility occurred, evaluations showed quality improvement with both algorithm implementations. However, the customized formulation based on individual hearing losses was similar in performance to the formulation based on the normal auditory system.

    Sensorineural hearing loss is a common disabling disease. The main therapy against this disease in the pres-ent age is that medication is administered via systemic application. However, due to the blood- labyrinth barrier, the concen-tration of drug performs low level when it is administered through systemic application, which causes low therapeutic effect against sensorineural hearing loss. This defect could be averted to large extent via local application, through which the blood-labyrinth barrier is bypassed. In the meantime, along with the developments the technologies of genetic engineering and cytology, local gene transfection and stem cell implantation are applied in the researches of treatments for sensorineural hear-ing loss. This review will examine the mechanism and the potential of therapeutics against sensorineural hearing loss via local application in cochlea.%感音神经性聋是一种常见的致残性疾病,药物治疗仍然是重要手段,全身给药是目前主要的给药方式。然而,由于血-迷路屏障的存在,全身给药方式给予的药物在耳蜗中分布的浓度较低,一些药物甚至不能通过血-迷路屏障,因此,常规全身给药方式治疗感音神经性聋的效果欠佳。而内耳局部注射的方式可有效绕过血-迷路屏障,可望克服全身给药耳蜗中药物浓度分布过低的缺陷;同时,随着基因工程技术和细胞学技术的飞速发展,耳蜗局部基因转染及耳蜗干细胞植入技术也被运用到感音神经性聋防治的研究中。本文将就内耳局部药物注射、局部基因转染及干细胞植入防治感音神经性聋的现状及展望进行综述。

    2005-09-01

    Full Text Available Abstract Background Cholesteatomas are epithelial cysts that contain desquamated keratin. Patients commonly present with progressive hearing loss and a chronically discharging ear. We report an unusual presentation of the disease with an acute hearing loss suffered immediately after prolonged use of a pneumatic drill. Case presentation A 41 year old man with no previous history of ear problems presented with a sudden loss of hearing in his right ear immediately following the prolonged use of a pneumatic drill on concrete. The cause was found to be a fractured long process of incus which had been eroded by the presence of an attic cholesteatoma. A tympanomastoidectomy and ossiculoplasty was performed with good result. Conclusion Cholesteatomas may be asymptomatic and insidious in their onset. This case illustrates the point that an indolent disease such as this may present in unusual ways and the clinician must always have a high index of suspicion combined with thorough assessment and examination of every patient.

    Full Text Available Introduction: Vestibular evoked myogenic potential (VEMP has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients.   Materials and Methods: We performed a cross sectional analysis on 20 healthy volunteers with normal pure-tone audiometry as a control group; and on a group of patients consisted of 20 participants with conductive hearing loss, five with bilateral sensorineural hearing loss and four with vestibular schawannoma. AC and BC-VEMP were performed in all participants.   Results: In control group the VEMP responses to both kinds of stimuli had an acceptable morphology and consisted of p13 and n23 waves. Latency value of these main components in each type of stimulus was not significantly different (P>0.05. However, the mean amplitude was larger in BC modality than AC stimulation (P=0.025. In the group with conductive hearing loss, the VEMP response was absent in fifteen (46.87% of the 32 ears using the AC method, whereas all (100% displayed positive elicitability of VEMP by BC method. Normal VEMP responses in both stimuli were evoked in all patients with sensorineural hearing loss. In patients with unilateral vestibular schwannomas (VS, 2 (50.00% had neither AC-VEMP nor BC-VEMP. Conclusion:  Auditory stimuli delivered by bone conduction can evoke VEMP response. These responses are of vestibular origin and can be used in vestibular evaluation of patients with conductive hearing loss.

    Higher levels of fibrinogen or cholesterol were associated with improved hearing recovery in SSHL patients after treatment with HELP-apheresis (Heparin-induced extracorporeal LDL precipitation apheresis). The present trial was performed to demonstrate HELP-related effects on relevant metabolic and inflammatory parameters in the context of SSHL treatment. In the framework of a single arm non-controlled trial, we investigated the variation of metabolic and inflammatory parameters using HELP-apheresis for a defined group of 100 patients with SSHL. Based on cut off inclusion criteria (Serum LDL-cholesterol >1.6 g/l and/or fibrinogen >2.0 g/l, SSHL in minimum three frequencies more than 30 dB, time after event not longer than 6 days), the protocol followed a strict time line with one single shot HELP-apheresis and follow-up monitoring including laboratory parameters at six defined time points. If HELP-apheresis could not effect improvement of hearing on day 5, additional corticosteroid treatment was applied. Concentration of anti-inflammatory IL-10 increased while other proinflammatory parameters declined. Serum levels of all measured sterols and apolipoproteins decreased significantly. None of the investigated parameters were suitable to predict hearing improvement of the patients. Levels of fibrinogen and LDL-cholesterol were not prognostic for outcome after HELP-apheresis. A significant (p apheresis was notable, while most of the proinflammatory parameters declined. Despite the limited validity of a single arm non-controlled trial, these alterations on immune modulating factors indicate possible secondary pleiotropic effects caused by HELP-apheresis.

    First aim of the study was to define normal shape and diameter of the internal auditory canal (IAC). In the second part the clinical relevance of IAC-enlargement was analyzed, considering also lesions of the subtle structures at the fundus of the internal auditory canal. 440 high resolution CT-scans of the temporal bone were used for retrospective analysis of the internal auditory canal and its fundus region. The mean value of the IAC diameter in axial and coronal plane was determined. In 20 of 440 patients IAC enlargement was found. In the group with pronounced enlargement (3fold SD) nearly all patients suffered from hearing impairment. In some of them we found structural abnormalities near the IAC fundus in the CSF/perilymph border zone. A new CT-based definition of normal shape and diameter of the internal auditory canal is presented. There is some evidence that a pathologic transmission of CSF-pressure in case of IAC-enlargement and/or abnormal fistulous communications could play an important role in the pathophysiology of hearing loss.

    The purpose of this study is to evaluate the significance of the hypoplastic canal for the cochlear nerve in patients with sensorineural hearing loss (SNHL) and the relationship between the hypoplastic bony canal and aplasia or hypoplasia of the cochlear nerve. A retrospective review of high resolution temporal CT(HRCT) and MRI findings was conducted. The narrow bony canal of the cochlear nerve and the relative size of the internal auditory canal were correlated with the cochlear nerve deficiency on MRI. The comparative size of the component nerves (facial, cochlear, superior vestibular, inferior vestibular nerve), and the relative size of the internal auditory canal and the bony canal of the cochlear nerve were measured. The clinical history and the results of the clinical examination were reviewed for each patient. High resolution MRI showed aplasia of the common vestibulocochlear nerve in one patient and a deficiency of the cochlear nerve in 9 patients. These abnormalities occurred in association with a prominent narrowing of the canal for the cochlear nerve and a stenosis of the internal auditory canal, which was observed on temporal bone CT in 9 patients with congenital SNHL. Three patients had normal IAC, despite the presence of a hypoplastic cochlear nerve on the side on which they had SNHL. In one patient, the narrowing of the canal for the cochlear nerve and internal auditory canal were not found to be associated with acquired SNHL. The hypoplastic bony canal for the cochlear nerve might be more highly indicative of congenital cochlear nerve deficiency than that of the narrow internal auditory canal, and the position of the crista falciformis should also be carefully.

    Recognized causes of high-frequency sensorineural hearing loss (SNHL) after tympanoplasty with and without mastoidectomy include acoustic trauma from manipulation of the ossicles, the noise generated by suctioning and, in the case of mastoidectomy, the noise generated by temporal bone drilling. We conducted a retrospective study to identify the effects of ossicular manipulation and mastoid drilling on high-frequency SNHL. Our study population was made up of 51 patients-20 males and 31 females, aged 10 to 59 years (mean: 28.5). Of this group, 26 patients had undergone a unilateral over-under tympanoplasty only (tympanoplasty group) and 25 had undergone a unilateral tympanoplasty plus additional mastoid surgery (mastoidectomy group). Bone-conduction audiograms were obtained pre- and postoperatively; the latter were obtained within 24 hours after surgery and again at 6 months of follow-up. In the tympanoplasty group, a significant SNHL, primarily at 2 kHz, was seen in 6 patients (23%) at 24 hours, but at 6 months there was no depression of bone-conduction thresholds. In the mastoidectomy group, a significant SNHL, primarily at 2 and 4 kHz, occurred in 12 patients (48%) at 24 hours, and bone-conduction deterioration was still present in 4 patients (16%) 6 months after surgery. The difference between the preoperative audiograms and the 6-month audiograms in both groups was statistically significant (p = 0.034). We conclude that (1) over-under tympanoplasty, which requires significant manipulation of the ossicles, can cause temporary SNHL after surgery, and (2) prolonged exposure to the noise generated by mastoid drilling can result in permanent SNHL.

    Salicylate, the active ingredient of aspirin can cause sensorineural hearing loss and tinnitus when plasma concentrations reach a critical level. The ototoxic mechanisms of salicylate remain unclear but hearing and tinnitus usually recovers a few days after intoxication. There have been few reports of salicylate-induced ototoxicity in Korea, and the majority is caused by a low dose of aspirin. Herein, we report a case of sudden hearing loss and tinnitus after acute salicylate intoxication and review recent updates on salicylate ototoxicity.

    Full Text Available Introduction: Long QT syndrome (LQTS is a repolarization cardiac disorder that can lead to syncope, cardiac arrest and sudden death in apparently healthy individuals. The congenital type can be accompanied with congenital sensory-neural deafness (Jervell-Lang-Nielsen syndrome. Although there are limited studies assessed the frequency of LQTS in these children in developed countries, regarding introducing the new formula, it is necessary to re-evaluate the frequency of this syndrome. Materials and Methods: This cross-sectional and descriptive study was done on 203 patients with congenital sensory-neural hearing loss (SNHL that had cochlear implant surgery in Baqiyatallah cochlear implant center from 2008 to 2012. Corrected QT was calculated with this formula: QTC = QT + 1.75 (heart rate-60 Patients with QTC > 460 ms, were categorized in four groups: Long QT: QT > 460, Borderline: 440 470 and very markedly: >500. Also, cardiac arrhythmias or arrest were evaluated in patients during cochlear implant surgery and in the postoperative recovery period. Result: Prevalence of LQTS in patients was 12.32% (25 patients. Prevalence of markedly long QT and very markedly long QT were 8.87% (18 patients and 2.46% (5 patients respectively. The prevalence of borderline group was 14.29% (29 patients. None of the patients during or after surgery were affected by cardiac arrhythmias or arrest. Conclusion: This study showed higher prevalence of LQTS in patients with SNHL than the normal population, and we suggest that all patients with congenital deafness should be screen for LQTS.

    Full Text Available Background: Sudden sensorinueural hearing loss (SSNHL is a baffling condition for patients, and its etiology, audiologic characteristics, prognostic factors, and treatment are still controversial. Methods: In this prospective study, we performed pure tone audiometry (PTA, impedance acoustics (IA, auditory brainstem responses (ABR, otoacoustic emissions (OAE, and transiently evoked otoacoustic emissions (TEOAE before beginning treatment for 53 patients with SSNHL. We then entered each patient, randomly and alternately, in one of two treatment groups: oral steroids + acyclovir vs. intravenous urographin. Results: In 22 (41.5% of the 53 patients (22 female, 31 male, we found negative or no signal to noise ratio and overall correlation in TEOAE. Furthermore, 26 cases (49% had positive overall correlations less than 50%, and five cases (4.4% had overall correlations >50%. Although 15 cases (28.3% responded well, 20 cases (37.7% showed only a partial response, and 18 cases (33.9% had poor or no response to our treatment. The mean value for overall correlation in the three subgroups of patients (no response, partial response, and complete response was -3.5% (±1/16%, + 11% (±1.99%, and +36.6% (±3.07% respectively (P = 0.01. From 52 cases, 20 had no reproducible wave in ABR (38.5%, three cases had abnormal ABR with normal OAE, all of which responded completely to treatments. Thirteen cases had abnormal ABR and OAE, none of which responded to treatment, and six cases had normal ABR with abnormal OAE, which often responded to treatment. Conclusions: ABR and OAE may be useful in the diagnosis of SSNHL and determining the site of such lesions as ischemia or neuropathy. The overall correlation (and S/N ratio in TEOAE is a valuable prognostic factor in SSNHL.

    It has been reported that about half of patients with sudden sensorineural hearing loss (SSNHL) show high signals in the affected inner ear on three-dimensional, fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI). These signals may reflect minor hemorrhage or an increased concentration of protein in the inner ear, which has passed through blood vessels with increased permeability. Our objective was to compare the positive ratio of the high signal in affected inner ears at different time points to determine the suitable imaging time point for 3D-FLAIR MRI in SSNHL. 3D-FLAIR MRI images were taken at three times, precontrast and approximately 10 min and 4 h after intravenous injection of a single dose of gadodiamide (Gd) (0.1 mmol/kg), in 46 patients with SNHL. We compared the positive findings of the high signals in the inner ear of patients with SNHL as well as the signal intensity ratio (SIR) between the affected cochleae and unaffected cochleae at three time points. The positive ratios of the high signals in the affected inner ear at the time points of precontrast and 10 min and 4 h after the intravenous Gd injection were 26.1, 32.6, and 41.3%, respectively. The high signal intensity ratios of affected inner ears at the three time points were 1.28, 1.31, and 1.48, respectively. The difference between the positive ratios precontrast and at 10 min after the intravenous Gd injection was statistically significant (P = 0.006); the differences between the positive ratios at 4 h after the intravenous Gd injection and precontrast and between the ratios at 4 h and 10 min after the intravenous Gd injection were not statistically significant. The time effects of the median value of SIR were not significant (P = 0.064). We do not recommend 4 h after intravenous Gd injection as a time point to image the inner ear in SNHL. We believe that imaging precontrast and at 10 min after the intravenous Gd injection are suitable time points.

Results ① Etiologies in the 73 cases included: low-tone sensorineural hearing loss (LSNHL, 21/73, 29%), Meniere disease (MD, 17/73, 23%), inner ear malforma-tion(12/73, 16%), delayed endolymphatic hydrops (DEH, 8/73,11%), autoimmune sensorineural hearing loss (ASNHL, 5/ 73, 7%), early stage acoustic neurinoma(4/73, 6%), noise-induced hearing loss(3/73,4%)and unkoown etiologies(3/73, 4%). No auditory neuropathy, perilymph fistula or vascular abnormalities was found in this group of patients. ② Hearing fluctuated only in the low frequency range in LSNHL and early stage MD eases, and only in the high frequency range in early stage acoustic neurinoma and noise-induced hearing loss cases.ASNHL and bilateral inner ear anomalies often showed symmetrical sensorineural hearing loss. ③ Causes of erroneous and missed diagnosis: Symmetrical enlarged vestibule abnormalities could show symmetrical and progressive sensorineural hearing loss attacks in adulthood. Most such cases could be identified by the precipitating factors of attacks, including sudden rises of intracranial or abdominal pressures. Radiology was helpful to differentiate these cases from those of ASNHL; Unilateral high-frequency hearing fluctuation often represented early stage acoustic neurinoma, which could be picked up by enhanced MRI as a routine test to avoid missed diagnosis. Conclusion FSNHLinvolves numerous etiologies. Correct diagnosis depends on not only history, symptomatology and audiology features, but also knowing the precipitating and occupational environment factors.%目的 探讨波动性感音神经性聋(FSNHL)的病因及其相应的临床特点,分析引起误诊及漏诊的原因,为

    Objective To determine the relationship between the 469K/E polymorphism (rs5498) of the ICAM-1 gene and sudden sensorineural hearing loss. Methods Subjects used in this study were derived from the Third Affiliated Hospital of Southern Medical University. Two milliliters of venous blood were obtained from each participant for genomic DNA extraction. Detection of SNPs rs5498 was performed by polymerase chain reaction (PCR), followed by restriction fragment length polymorphism (RFLP) analysis. The restriction enzyme-digested PCR products were analyzed by 2% agarose gel electrophoresis. The Chi-square test was used to compare the frequency of alleles and genotypes between case and control groups. Results Seven-ty-five SSNHL patients (39 male and 36 female patients) were compared with 165 controls (86 male and 79 female subjects) enrolled in this study from June 2014 to July 2015. No significant differences in ICAM-1 469K/E genotype and allele frequencies were found between the SSNHL group and controls. However, there were significant differences in ICAM-1 469K/E polymorphism between patients with different types of hear-ing loss. Conclusion Our study results do not show significant association between 469K/E polymorphism of the ICAM-1 gene and sudden sensorineural hearing loss. The E allele may influence the susceptibility to the development of flat type of hearing loss.%目的:探讨细胞粘附分子-1(ICAM-1)469K/E基因多态性是否与突发性聋存在相关性。方法按照入选标准共选取了240例研究对象,包括突发性聋患者75例(男39例,女36例),对照者165例(男86,女79例),分别抽取2ml外周静脉血,提取DNA,PCR扩增目的片段,扩增产物经限制性酶切后行琼脂凝胶电泳,以此确定所有研究对象ICAM-1469K/E的基因分型。通过统计分析明确ICAM-1469K/E与突发性聋是否相关。结果两组之间ICAM-1469K/E基因分型及等位基因分布频率差异无统计学意义,

    Sensorineural hearing loss is a common disease and apoptosis of cochlear cells is one of the most common causes. Insulin like growth factor-1(IGF-1) activates cell cycle and inhibits apoptosis by diverse signal transduction pathways,plays an important role in the regulation of cochlear growth, development and differentiation,and maintaining cochlear survival and recovery under cochlear cell damage. There were some progresses in the treatments of sudden deafness and drug deafness by local application of IGF-1.%感音神经性耳聋是耳鼻咽喉科常见病,耳蜗细胞凋亡是感音神经性耳聋的主要原因之一。IGF-1通过多种信号转导途径激活细胞周期和抑制细胞凋亡,从而参与耳蜗细胞正常的生长、发育和分化,以及在耳蜗细胞损伤时参与维持细胞的存活和修复。IGF-1局部应用对于治疗突发性聋、药物性聋等感音神经性聋方面的研究取得了进展。

    This report describes an algorithm developed to predict the pathogenicity of copy number variants (CNVs) in large sample cohorts. CNVs (genomic deletions and duplications) are found in healthy individuals and in individuals with genetic diagnoses, and differentiation of these two classes of CNVs can be challenging and usually requires extensive manual curation. We have developed PECONPI, an algorithm to assess the pathogenicity of CNVs based on gene content and CNV frequency. This software was applied to a large cohort of patients with genetically heterogeneous non-syndromic hearing loss to score and rank each CNV based on its relative pathogenicity. Of 636 individuals tested, we identified the likely underlying etiology of the hearing loss in 14 (2%) of the patients (1 with a homozygous deletion, 7 with a deletion of a known hearing loss gene and a point mutation on the trans allele and 6 with a deletion larger than 1 Mb). We also identified two probands with smaller deletions encompassing genes that may be functionally related to their hearing loss. The ability of PECONPI to determine the pathogenicity of CNVs was tested on a second genetically heterogeneous cohort with congenital heart defects (CHDs). It successfully identified a likely etiology in 6 of 355 individuals (2%). We believe this tool is useful for researchers with large genetically heterogeneous cohorts to help identify known pathogenic causes and novel disease genes.

    Objective To clarify the different prognostic characteristics between profound sudden sensorineural hearing loss (SSNHL) and total SSNHL. Methods The patients with SSNHL who visited Eye Ear Nose and Throat Hospital from June 2007 to September 2008 were reviewed retrospectively. All the 204 patients, with pure tone average (PTA) threshold more than 90 dB, were enrolled and divided into two groups, including total SSNHL and profound SSNHL groups. The relationship between recovery rate and prognostic factors including the age, complications, time period between onset and therapy was analyzed.Results There were 57 cases of total SSNHL and 147 cases of profound SSNHL in this series. Tinnitus was complained in more than 90% of the patients in both groups, which was higher than that of dizziness and ear fullness. Dizziness was present in 64. 9% (37/57) patient with total SSNHL group and 45.6% (67/147)patients with profound SSNHL, which had significant difference between the two groups (x2 = 5.72,P =0. 017). The PTA threshold improvement in total SSNHL group and profound SSNHL group was (36. 4 ±19.3) dB and (40. 2 ±21.3) dB respectively, which was no significant difference between the two groups (t = 1. 165 ,P =0. 245). The cured patients were all those received therapy within 1 week following the onset of SSNHL, which was of 2. 6% (1/38) patients in the total SSNHL group and 14. 3% (14/98) patients in the profound SSNHL group(P =0. 045). Furthermore, 3.5% (2/57) patients in total SSNHL group as well as 29. 9% (44/147) patients in profound SSNHL group obtained a good result with PTA threshold ≤50 dB after therapy(x2 = 15.92,P = 0. 001 ). In addition, the favorable prognosis was related with the onsettherapy time point( P = 0. 001 ), but not related to the patients' age. Conclusion Profound SSNHL and total SSNHL though both with PTA threshold > 90 dB had significant differences recovery rate and need to be studied separately.%目的 研究突发性极重度聋和全聋

    Full Text Available Sudden sensorineural hearing loss (SSNHL is one of the autoimmune diseases of the inner ear (AIED, which is characterized by a hearing loss of above 30 decibels in at least three contiguous audiometric frequencies over a time course of 72 hours or shorter. Its cause can be found in only 10% to 15% of patients. Histopathologic findings have reported retrograde neuronal degeneration and atrophy of Corti's organ and of the vascular stria. This paper describes a case of a middle-aged female patient undergoing a treatment for hyperthyroidism who developed bilateral SSNHL. The patient was treated with methylprednilisone (1mg/kg/day for three days with considerable hearing improvement. This treatment was followed by lung and kidney tuberculosis. The immune mechanism of this entity and the possibility of interconnected participation of the antigen type, of an autoimmune disease and of bacterial infection are discussed.A surdez neurosensorial aguda (SNSA é uma das doenças auto-imunes do ouvido interno caracterizada pela perda da audição acima de 30 decibéis, em pelo menos 3 freqüências audiométricas contíguas, no período máximo de 3 dias. Sua causa só é definida em 10 a 15% dos pacientes. Achados histopatológicos demonstram degeneração neuronal retrógrada e atrofia do órgão de Corti e da estria vascular. Relatamos o caso de uma paciente de média idade em tratamento de hipertireoidismo que apresentou SNSA bilateral. A paciente foi tratada com metil-prednisilona (1mg/kg/dia durante três dias evoluindo para uma melhora considerável da audição. Este tratamento foi seguido de tuberculose pulmonar e renal. Discute-se o mecanismo imunológico desta entidade, e a possibilidade de participação cruzada do tipo antígeno, doença autoimune e infecção bacteriana.

    Conclusion This study demonstrated excellent hearing recovery following the combined treatment of diuretic and oral steroid, and electrocochleography (ECoG) was significantly higher than normal side. This study reports characteristics of acute low-tone hearing loss (ALHL) that show the greater low-tone hearing loss, the higher ECoG, and excellent recovery, even-though low-tone hearing loss is worse, which can be different compared with sudden deafness. Objective To analyze ALHL without vertigo, this study compared the ALHL group with all patients exhibiting low-tone hearing loss and ear fullness. Hearing changes and vestibular functions were analyzed. Materials and methods ALHL was defined as a mean hearing loss of ≥ 30 dB at 125, 250, and 500 Hz, and ≤ 20 dB at 2, 4, and 8 kHz. From 156 cases of low-tone hearing loss of more than 10 dB without vertigo, 31 met the ALHL criteria and were subjected to audio-vestibular assessments including PTA, ECoG, vestibular evoked myogenic potential (VEMP) testing, and caloric testing. Results In ALHL, low-tone hearing loss was 42.7 ± 9.5 dB, and 83.9% of ALHL significantly recovered by more than 10 dB. The ECoG in ALHL was 0.334 ± 0.11 (higher than 0.25 ± 0.08 on the normal side) and ECoG abnormality was 35.5% (the greater low-tone hearing loss, the higher ECoG value).

    2015-06-01

    This article carries out a literature review of the advantages and limitations of the simultaneous bilateral cochlear implantation (SCI) compared to those of the sequential bilateral cochlear implantation (SBCI) and the unilateral cochlear implantation (UCI). The variables analysed in said comparison are: safety and surgical technique, SCI incidence, effectiveness, impact of the inter-implant interval, costs and financing, impact on brain plasticity, impact on speech and language development, main benefits, main disadvantages and concerns, and predictive factors of prognosis. Although the results are not conclusive, all variables analysed seem to point towards observable benefits of SCI in comparison with SBCI or UCI. This tendency should be studied in more depth in multicentre studies with higher methodological rigour, more comprehensive samples and periods and other determining variables (age at the time of implantation, duration and degree of the hearing loss, rehabilitation methodologies used, family involvement, etc.).

    Introduction Sensorineural emergencies (SNE) are rare clinical situations. Few patients consult early explaining subsequent difficulty in having accurate data and management. Three clinical conditions are considered SNE in otolaryngology; they include sudden sensorineural hearing loss (SSHL), Bell's palsy and acute vertigo. There is very little data available on sensorineural emergencies in our setting. The aim of this study was to provide preliminary data on the management of Ear Nose and Throat (ENT) sensorineural emergency cases in Yaoundé Reference Hospital. Methods A descriptive retrospective study was carried out based on data collected over a period of 5 years, January 2010 to July 2014 at the Yaoundé Reference Hospital. Information was obtained from patients’ files collected from the archives of the institution. Patients presenting with SSHL, Bell's palsy, acute vertigo who consulted during the study period were included in the study. Results A total of 22 patients were included in the study out of 6406 patients who consulted at the ENT Unit. The prevalence of SNE in ENT consultations was 0.003, distributed as follows; 13 patients (59.1%) of SNE had Bell's palsy, seven (31.8%) had vestibular neuritis and two (9.1%) had SSHL. Conclusion The prevalence of SNE was low with idiopathic Bell's palsy being the most frequent. There was a general delay in arrival of patients hence delay in diagnosis. This delay could equally be a factor for treatment failure and poor prognosis. More effort should be made in terms of population sensitization about the necessity of getting early medical attention.

Method Studied were 25 patients who had received transtympanic lidocaine and methylprednisolone injec-tion after having failed with intravenous steroids and other medications from Aug 2008 to Mar 2012. They all had received intravenous dexa-methasone and other medicatio ns for two weeks and no improvement of hearing. The transtympanic lidocaine and methylprednisolone injec-tions were administered with oto-endoscope twice a week for 2 weeks. Hearing and tympanic membrane were monitered one month after the termination of injectio ns. Hearing improvement was defined as more than 15 dB in pure tone average( PTA). Results 8 patients had im-provement of hearing( 32%)according to the PTA. The thresholds of 500,1 000 and 2 000 Hz decreased obviously( P﹤0. 05). Conclu-sion Transtympanic lidocaine and methylprednisolone injection can be considered as a salvage treatment for refractory sudden sensorineural hearing loss.

    Full Text Available Abstract Background Vasospasm of the spiral modiolar artery (SMA may cause ischemic stroke of the inner ear. Endothelin-1 (ET-1 induces a strong, long-lasting constriction of the SMA by increasing contractile apparatus Ca2+ sensitivity via Rho-kinase. We therefore tested several Rho-kinase inhibitors and a cell-permeable analogue of cAMP (dbcAMP for their ability to reverse ET-1-induced constriction and Ca2+-sensitization. Methods The present study employed SMA isolated from gerbil temporal bones. Ca2+sensitivity was evaluated by correlating vascular diameter and smooth muscle cell [Ca2+]i, measured by fluo-4-microfluorometry and videomicroscopy. Results The Rho-kinase inhibitors Y-27632, fasudil, and hydroxy-fasudil reversed ET-1-induced vasoconstriction with an IC50 of 3, 15, and 111 μmol/L, respectively. DbcAMP stimulated a dose-dependent vasodilation (Ec50 = 1 mmol/L and a reduction of [Ca2+]i (EC50 = 0.3 μmol/L of ET-1-preconstricted vessels (1 nmol/L. Fasudil and dbcAMP both reversed the ET-1-induced increase in Ca2+ sensitivity. Conclusion Rho-kinase inhibition and dbcAMP reversed ET-1-induced vasoconstriction and Ca2+-sensitization. Therefore, Rho-kinase inhibitors or cAMP modulators could possess promise as pharmacological tools for the treatment of ET-1-induced constriction, ischemic stroke and sudden hearing loss.

    Objective To investigate the relationship between expression of glucocorticoid receptor(GR) in peripheral blood mononuclear cells(PBMCs)of patients with sudden sensorineural hearing loss(SSNHL) and therapeutic effect, and the ef⁃fect of glucocorticoid(GC)to expression of GR. Methods 196 patients with SSNHL were randomly divided into two groups:pa⁃tients in groups A were treated by prednisone and Ginaton, patients in groups B were only treated by prednisone. Patients were divided into responders and nonresponders according to therapeutic effect . The mRNA express of GRαand GRβin PBMCs of every patient was detected by real time quantitative RT-PCR on pretherapy and post-therapy.The difference of GRαmRNA , GRβmRNA and GRα/GRβamong groups and between pretherapy and post-therapy was analyzed. Results 150 patients with SSNHL were GC sensitive and 46 patients were GC resistan. On pretherapy, there were GRαand GRβmRNA in PBMCs of all patients, GRαwas visibly more than GRβ, there were not obvious difference of GRαmRNA ,GRβ mRNA and GRα/GRβ in PBMCs among responders and nonresponders between two groups . There was no statistical difference of GRαmRNA between responders and nonresponders in the same group. GRβmRNA of nonresponders was significantly more than that of responders(P<0.01), GRα/GRβof nonresponders was significantly lower than that of responders(P<0.01) . On post-therapy, there were also not obvious difference of GRαmRNA ,GRβmRNA and GRα/GRβamong responders and nonre⁃sponders between two groups. GRαmRNA ,GRβmRNA and GRα/GRβwere all significantly decreased in both groups than pretherapy(P<0.01 in responders, P<0.05 in nonresponders). Conclusion GRβmRNA in PBMCs of patients with SSNHL is inversely correlative with the hearing prognosis ,whereas GRαmRNA is independent on the hearing prognosis.GC can down-regulate GRαmRNA and GRβmRNA of patient with SSNHL. Ginaton has no effect to the expression of GRαand GRβmRNA of patient with

    determine inheritance patterns. Through a high suspicion index, syndromic cases can be diagnosed or excluded, with a careful evaluation and molecular basis tests used to better determine the hearing loss. Genetic tests and mitochondrial inheritance should be considered in any family with many affected individuals, except when the hearing loss was clearly transmitted by a male. In cases of non-syndromic SNHL, GJB2 mutation analysis must be proposed.

    Background The mutation frequencies of three common deafness genes (MT-RNR1 m.1555A>G,GJB2,and SLC26A4) among patients with nonsyndromic sensorineural hearing loss (NSHL) were different in previous studies.Inconsistent selection criteria for recruiting patients could have led to differences in estimating the frequencies of genetic mutations thus resulting in different mutation frequencies among these studies.The aim of this study was to reveal the differences in the mutation spectrums of the three common genes between familial and sporadic Chinese Han patients.Methods Totally,301 familial probands and 703 sporadic patients with NSHL were enrolled in this study.Three genes,MT-RNR1 m.1555A>G,GJB2,and SLC26A4,were screened for mutation in our study cohort.A X2 test was performed to compare the mutation frequencies between the two groups.Results The study showed that the disease-causing mutation frequencies of MT-RNR1 m.1555A>G,GJB2,and SLC26A4 were 12.29%,14.62%,and 18.27% in familial probands and 3.56%,18.63%,and 18.92% in sporadic patients,respectively.The mutation frequency of MT-RNR1 m.1555A>G in familial probands was significantly higher than in sporadic patients (X2 test,P=0.000),while there were no significant differences in the mutation frequencies of GJB2 and SLC26A4 between the familial and sporadic groups (X2 test,P >0.05).Conclusions It is necessary to reveal the differences in gene mutation frequencies between patients of different sources or characteristics by comparative studies in order to avoid selection bias.The mutations of GJB2,SLC26A4,and MTRNR1 m.1555A>G are the most important etiological factors in Chinese Han patients,among which SLC26A4 might be the most frequent.

    Full Text Available OBJECTIVE: To describe the MRI findings of two pediatric patients with sudden sensorineural hearing loss (SSHL. CASE REPORTS: Two male patients (two-year and three-months-old, and one year and four-months-old presented with sudden dumbness. Physical and neurological examinations were unremarkable besides bilateral hypoacusia. All the laboratory investigation was negative, and brain stem auditory evoked potentials showed deep bilateral deafness in both cases. MRI studies revealed normal inner ears and multifocal white matter areas of slight low signal on T1-weighted images and high signal on FLAIR images. The follow-up MRI studies and neurological examinations did not demonstrate alterations in the previous findings. CONCLUSION: Pediatric patients with SSHL may present cerebral white matter signal abnormalities at the MRI as the only finding. Further studies with larger casuistics need to be conducted to elucidate these findings.OBJETIVO: Descrever os achados de ressonância magnética (RM em dois pacientes pediátricos com perda auditiva neuro-sensorial súbita (PANS. RELATO DOS CASOS: Dois pacientes masculinos (dois anos e três meses e um ano e quarto meses de idade apresentaram-se com surdez súbita. Os exames físico e neurológico foram normais, à exceção da hipoacusia. Toda a investigação laboratorial foi normal, e os potenciais auditivos evocados do tronco cerebral demonstraram surdez profunda bilateral. Os exames de RM evidenciaram estruturas normais dos ouvidos internos e áreas multifocais de discreto hipossinal em T1 e hipersinal em FLAIR na substância branca dos hemisférios cerebrais. As RMs e os exames neurológicos de controle não demonstraram alterações nos achados prévios. CONCLUSÃO: Pacientes pediátricos com PANS podem apresentar à RM alterações de sinal na substância branca dos hemisférios cerebrais como único achado. Estudos futuros com casuísticas maiores deverão ser conduzidos para a elucidação destes

    To investigate the condition of the hearing and speech in subjects from 2 families with delayed dominant hereditary sensorineural deafness. Methods: The investigation of deafness heredity and the examination of systemic audiology were made in the 2 families. Results: The examination of pure tone hearing threshold showed that hearing threshold in all frequency ranges were severely elevated, the curve of hearing threshold revealed the descending type in 6 cases of the 2 families,among whom there were only residual hearings at low frequency in 3 ears of 2 cases,The ages of onset of hearing loss of the 2 families have some characteristics: the onset became younger, the course was shorter, the degree of deafness was worse from generation to generation. The earlier the onset of hearing loss was,the worse the speech function was. Conclusion:Ge netic counseling and health education are important in reducing incidence of hereditary hearing loss. Hearing monitoring should be carried out periodically for children with history of hereditary hearing loss in their families. Hearing aids should be prescribed for probands as soon as hearing loss is verified. Speech rehabilitation is also advised when indicated.%探讨2家系迟发性显性遗传性感音神经性聋的听力和言语情况。方法:对2家系进行耳聋遗传调查和系统的听力学检查。结果:2家系6例纯音听阈检查示全频程听阈重度升高,听阈曲线呈缓降型,其中2例3耳仅低频听力残存。2家系耳聋发生年龄有逐代提前、代代相传、病程缩短、耳聋程度加重的特征。发生耳聋的年龄愈小,言语功能愈差。结论:应加强对遗传性聋的咨询、指导以及宣传工作。尽力减少或控制遗传性耳聋的发生率,对有家族遗传史者应定期进行听力学监测,对已发生耳聋者应及早配戴助听器并进行适当的言语训练。

    Full Text Available Importance. Rituximab was not effective in ameliorating the hearing loss in a patient with atypical Cogan’s syndrome. Observations. We report the case of a patient who developed acute bilateral uveitis and sensorineural hearing loss. A diagnosis of atypical Cogan’s syndrome was made. The patient’s hearing loss did not improve despite high dose steroids and azathioprine. Rituximab was administered given a recent report of its efficacy in a patient with refractory disease; however, our patient’s hearing loss did not improve. Conclusion. Hearing loss in Cogan’s syndrome is difficult to treat. Though rituximab was ineffective in our case, earlier administration in the disease course could be effective for future patients.

Methods 46 diabetics with sudden hearing loss were assigned to treatment group (n = 21) and control group ( n = 25 ). Simultaneously vasodilation, neurotrophy and insulin hypoglycemia were administered in both groups. Patients in treatment group were additionally managed with intratympanic dexamethasone (5 g/L) injection five times within 10 days. Pure tone test was conducted after intervention. Results The overall effective rates of the treatment group and the control group were 71.4% and 40. 0% respectively, and the difference was statistically significant ( P < 0. 05 ). No unexpected adverse events such as acute otitis media, perforated tympanic membrane and worsening in hearing occurred during the injection and follow-up period in the treatment group. Conclusion Intratympanic dexamethasone injection is an effective treatment for sudden hearing loss in patients with diabetes and can avoid undesirable side effects. Therefore, intratympanic dexamethasone injection may be a reasonable alternative as an initial treatment of sudden hearing loss in patients with diabetes.

    Mental health nurses do not always feel at ease talking in detail with voice hearers about their experiences. Using the approach of Romme and Escher, a project was developed to support staff on an acute inpatient ward to explore voice hearing with patients. Romme and Escher suggest that a person's own understanding of their voices and their meaning is the key to recovery. Working together, the nurse helps voice hearers construct a narrative that tells the story of their voices. Examples from the narratives show how they can help increase understanding of a person's voices, and how the mental health nurse in acute care can realistically offer therapeutic interventions that may help a person towards recovery.

    Science.gov (United States)

    Jafari, Gholamali; Hosseini, Seyed Mohammadreza; Akhondzadeh, Shahin

    2014-01-08

    Sudden sensorineural hearing loss (SSNHL) is a debilitating condition with an incidence of nearly 20 per 100,000 in populations. Metronidazole-induced ototoxicity is an extremely rare etiology of SSNHL. In this report, we describe a young female with bilateral SSNHL due to oral use of metronidazole. A 23 years old female presented to the emergency department with acute bilateral hearing loss. We found out that her hearing loss had started 4 days after initiation of metronidazole which was administered for treatment of diarrhea. This case report shows that physicians should be aware of the uncommon side effects while prescribing metronidazole to patients in order to manage the possible adverse events on time.

  2. Mechanisms of Sensorineural Cell Damage, Death and Survival in the Cochlea

    Directory of Open Access Journals (Sweden)

    Allen Frederic Ryan

    2015-04-01

    Full Text Available The majority of acquired hearing loss, including presbycusis, is caused by irreversible damage to the sensorineural tissues of the cochlea. This article reviews the intracellular mechanisms that contribute to sensorineural damage in the cochlea, as well as the survival signaling pathways that can provide endogenous protection and tissue rescue. These data have primarily been generated in hearing loss not directly related to age. However, there is evidence that similar mechanisms operate in presbycusis. Moreover, accumulation of damage from other causes can contribute to age-related hearing loss. Potential therapeutic interventions to balance opposing but interconnected cell damage and survival pathways, such as antioxidants, anti-apoptotics, and pro-inflammatory cytokine inhibitors, are also discussed.

    Sudden sensorineural hearing loss (SSHL) is defined as a unilateral or bilateral sensorineural hearing loss with at least 30 dB decrease in threshold in 3 contiguous test frequencies occurring over 72 hours or less. It is very rare in children. Sudden hearing loss is a symptom that suggests that there is a problem in the inner ear, surrounding structures, or the whole organism. The etiology and development of this disorder are still not fully understood. The literature contains numerous models of the pathogenesis of SSHL, with childhood SSHL having certain peculiarities. In practical terms, the multifactorial nature of SSHL is important in the choice of diagnostic methods and treatment methods. It is important to determine the cause and effect relationship between the underlying disease and hearing loss.

    Full Text Available Introduction : Mobile phone usage is widespread and concerns have been raised on the safety of its long-term usage. The electromagnetic fields emitted from mobile can penetrate skull and deposit energy 4-6 cm into the brain resulting in heating of the tissue. In this study, we explore a possible relationship between prolonged mobile phone usage and sensorineural deafness. Materials and Methods: The study was conducted in a medical college situated in rural India. A total of 100 persons between the age group of 20-45years using mobile phone for at least 5 years are selected and screened for sensorineural deafness. Use of cellular phones was assessed by a questionnaire. Mean number of daily calls and minutes were asked for to calculate the cumulative use in hours for all years. The most frequently used ear during cellular phone calls was noted, or whether both ears were used equally. Otoscopic examinations were performed by an otolaryngologist before testing in order to rule out any external or middle ear pathology that could affect audiometric measurements. The hearing levels of subjects were tested using pure tone audiometry. Results : One hundred subjects who are habitual mobile phone users were screened by pure tone audiometry. It is found that the prevalence of sensorineural deafness was 3% and there is a linear relationship between the duration of mobile phone use and the degree of the severity of deafness. Conclusion : The prevalence of sensorineural deafness in our study in habitual mobile users is 3%. It is not clearly known whether mobile phone use is the direct cause of deafness in these subjects but the absence of other causes might point towards its etiological role.

    This study was performed to analyze clinical and audiologic characteristics of sensorineural tinnitus and to investigate the associating factors reflecting psychological aspects of stress and depression of the patients. This is a retrospective analytical study conducted in a tinnitus clinic of a tertiary referral center of a university hospital. The medical records of 216 patients suffering from sensorineural tinnitus were thoroughly evaluated to determine correlations between clinical and audiological characteristics, including age, sex, predisposing or etiologic factors, hearing levels up to extended high frequencies, and tinnitus severity. Psychological aspects of stress and depression were also evaluated and analyzed to seek the associations with tinnitus severity. All data were stored in our database bank and were statistically analyzed. Our study subjects showed a slight male predominance. The highest percentage of tinnitus was found in patients of 60-80 years old. Only 32.5 % of tinnitus patients were subjectively aware of their hearing loss, whereas 73 % of subjects had hearing deficits in some frequencies in their audiogram. Hearing impairments were of the low-frequency sensorineural type in 18.2 % of patients and were limited to the high frequencies in 77.9 % of patients. Tinnitus was unilateral in 51 % of patients and had a tonal nature in 45 % of patients. In total, 45.8 % of patients with high-frequency sensorineural hearing loss had high-pitched tinnitus. There were significant correlations between tinnitus severity, loudness and annoyance. Correlations with THI (Tinnitus Handicap Inventory) and Beck depression index scores were also found. Sensorineural tinnitus was related with hearing loss in some frequencies nevertheless of patients' own awareness of hearing loss. Loudness and annoyance of tinnitus seems to be two important factors reflecting psychological problems of patients' stress and depression.

    Full Text Available The aim of this study was to measure the frequency of hearing loss in a sample of typical public high-school students exposed to recreational noise, and determine associated risk factors. The sample was made up of 214 teenagers from a high-school in Mexico City; subjects were selected randomly per strata. We applied a questionnaire to identify risk factors for hearing loss and performed a battery of audiologic tests consisting of otoscopy, tympanometry, and pure-tone audiometry. The mean age of the sample was 16 ± 1.07 years; 73% were male and 27%, female. Hearing loss was found in 21% of students. The main hearing loss-related risk factor was exposure to recreational noise: frequent attendance at discotheques and pop-music concerts; use of personal stereos; and noise exposure in school workshops. The high frequency of hearing loss in high school students from one Mexico City school (nearly one fifth of the sample was found to be related to noise exposure mainly during recreational activities.El objetivo de este estudio fue medir la frecuencia de alteraciones auditivas en una muestra de escolares de educación media superior expuestos a ruido recreativo y determinar algunos factores de riesgo asociados.

    The neuromagnetic index of hemispheric asymmetry in terms of ipsilateral/contralateral ratio at acute stage was previously revealed to prognosticate the 1-month hearing outcome of acute unilateral idiopathic sudden sensorineural hearing loss (ISSNHL), showing a dynamic relationship between top- and down-levels of auditory pathway. However, the prognostic effect of reorganization pattern for the long-term results remained elusive. This study aimed to probe the prognosticating relevance of hemispheric asymmetry to the hearing at chronic stage of ISSNHL. Using magnetoencephalography (MEG), inter-hemispheric differences in peak dipole of N100m responses to monaural tones were evaluated in 21 controls and 21 ISSNHL patients at initial and final (12 months later) stages. Predictive value of hemispheric asymmetry was assessed by correlating hearing level and ipsilateral/contralateral ratio (I/C) of N100m latency and amplitude. Healthy-side dominance of N100m was observed in ISSNHL initially, and remained in three final prognostic subgroups (complete, partial, and no recovery) of ISSNHL. The initial I/C(amplitude) on affected-ear stimulation strongly correlated with the hearing level of final stage in ISSNHL. However, there was no prognostic effect of hemispheric asymmetry pattern for the 12-month hearing improvement. The heterogeneity between neuromagnetic index and hearing levels possibly echoed different pathogeneses of ISSNHL. Since a restored hearing status did not necessarily lead toward a normal functional organization, the dynamics of hemispheric asymmetry could actually index a central resilient reorganization in the brain for sound processing in ISSNHL. Our finding showed not only a clinically relevant measure to predict final hearing of ISSNHL, but also a linkage between central plasticity and cochlear lesion. This finding suggests a new perspective, and perhaps new interventions, to diagnose and treat unilateral ISSNHL.

    Non-syndromic X-linked deafness is a rare form of genetic deafness in humans accounting for a small proportion of all hereditary hearing loss. Different clinical forms of non-syndromic X-linked deafness have been described, and most of these have been mapped. Here, we report a Chinese family affected by a congenital profound sensorineural hearing loss. All phenotypes of this family are clinically compatible with non-syndromic sensorineural deafness (DFN2). A maximum two-point Lod score of 2.32 was obtained at marker DXS6797 ( = 0.00). Recombinants define a region of 4.3 cm flanked by markers DXS6799 and GATA172D05. This region overlaps the previously reported DFN2 region by 2.0 cm.

  20. Vibrant Soundbridge rehabilitation of conductive and mixed hearing loss.

    2014-12-01

    The Vibrant Soundbridge is the world's most often implanted active middle ear implant or hearing aid. During the last few years, the device indications have expanded from sensorineural hearing loss to conductive and mixed hearing loss. Titanium couplers have led to improved contact of the floating mass transducer with the middle ear structures. The resulting hearing gain is satisfying for most patients, but so far, there is no clear audiologic advantage over conventional hearing aids. Currently, the indications are mainly related to intolerance of conventional hearing aids (eg, chronic otitis externa), severe mixed hearing loss with a destructed middle ear and certain medical diagnosis (eg, congenital atresia).
