Exploring quality of life post sudden onset hearing loss: A convergent parallel approach.

BACKGROUND:  Sudden onset hearing loss (SOHL) is rare and presents differently to individuals; hence, it is complex to diagnose. The impact on the quality of life (QoL) varies for individuals and their support structure. However, the exploration of research designs is warranted. OBJECTIVES:  This study explored the lived experiences of adults post-SOHL diagnosis and the impact on the QoL. Facilitators of emotional and social aspects of counselling provided by audiologists post-SOHL diagnosis were established. METHOD:  This was a convergent parallel research study. Data were collected from the two primary participants and three secondary participants, face-to-face and telephonically. The Hearing Handicap Inventory for Adults (HHIA) screening tool and the semi-structured interviews were used for data collection. The data sets were analysed independently, viz. descriptive analysis and thematic analysis, to confirm the impact on the QoL post-SOHL diagnosis. RESULTS:  The HHIA scores obtained were 84% and 50% for P1 and P2, respectively. Key themes that emerged from the interviews revealed that communication difficulties mostly impacted the QoL, which in turn influenced their mental and social well-being. Aural rehabilitation was perceived as ineffective support, thus the inability to reduce the impact on the QoL post-SOHL diagnosis. CONCLUSION:  The integrated findings indicated the impact on the QoL post-SOHL diagnosis. Convergent parallel methods should be considered by researchers to understand rare auditory pathologies and their impact on the QoL.Contribution: Person-centred care (PCC) and family-centred care (FCC) are facilitators of counselling that audiologists can employ as QoL management strategies post-SOHL diagnosis.

The Value of Plasma Atherogenic Index in Prognosis of Sudden Hearing Loss.

BACKGROUND: The impact of lipid parameters on hearing loss has been extensively studied in the literature. However, there is currently no study investigating the prognostic factor of plasma atherogenic index in patients with sudden hearing loss. This study aimed to evaluate the relationship of plasma atherogenic index in patients with sudden hearing loss. METHODS: Plasma atherogenic index is calculated using the logarithmic ratio of triglycerides [mg/dL] to high-density lipoprotein cholesterol ([mg/dL]) based on lipid parameters. The patients were divided into tertiles according to their plasma atherogenic index values and the role of plasma atherogenic index on prognosis was investigated among the tertiles. The difference between baseline and control audiometer values for each patient was calculated, and a linear regression analysis was used to determine its statistical significance. RESULTS: A total of 84 sudden hearing loss patients (57 male: 68%; 27 female: 32%) were included in the study. The mean age of the study participants was 45.3 ± 14.0. There was an inverse relationship between plasma atherogenic index and difference of audiometer values. Linear regression analyses revealed odds ratio and 95% confidence intervals of 0.405 (0.123-1.331) with P=.135 for 500 Hz, 0.371 (0.071-0.990) with P=.048 for 1000 Hz, 0.319 (0.119-0.851) with P=.024 for 2000 Hz and 0.406 (0.161-0.992) with P=.049 for 4000 Hz. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate that plasma atherogenic index can serve as an indicator of a poor prognosis in the treatment of sudden hearing loss.

High-Dose Glucocorticoids for Treating Sudden Hearing Loss: Cart before the Horse?

Hearing impairment is the most common sensory deficit. It affects 2 to 3 of 1000 newborns and nearly 50% of adults 75 years of age and older in the United States.1 Idiopathic sudden sensorineural hearing loss (ISSNHL) is characterized by an abrupt hearing loss requiring immediate diagnosis and treatment. Systemic glucocorticoids are widely used as the primary treatment for ISSNHL,2 but no head-to-head comparisons of the effectiveness and risk profiles of high doses over a more commonly used lower dose of glucocorticoids have been conducted to inform standard-of-care practice.

[Role of intratympanic glucocorticoid treatment in sudden hearing loss]. / Stellenwert der intratympanalen Glukokortikoidtherapie in der Behandlung des Hörsturzes.

Idiopathic sudden sensorineural hearing loss (ISSNHL) is one of the most common diseases in otolaryngology. Its etiology remains unknown. Furthermore, there is only a low level of evidence for the efficacy of established treatment modalities. In addition to systemic glucocorticoids, intratympanic corticosteroid treatment (ICT) has become increasingly important for treatment of ISSNHL. Different application strategies and treatment regimens have been described; however, uniform standards do not yet exist. ICT may be used for primary treatment as well as salvage therapy. Current data from meta-analyses show no benefit of intratympanic versus systemic primary therapy for sudden hearing loss (moderate evidence) but suggest a benefit of intratympanic secondary treatment over no treatment or placebo (high effect size, low evidence). Regarding combination of systemic and local glucocorticoid therapy in primary treatment of hearing loss, there may be a small benefit over systemic treatment alone (low effect size, low evidence).

[A case of sudden hearing loss combined with familial hyperlipidemia].

Hyperlipidemia is characterized by elevated levels of blood lipids. The clinical manifestations are mainly atherosclerosis caused by the deposition of lipids in the vascular endothelium. The link between abnormal lipid metabolism and sudden hearing loss remains unclear. This article presents a case study of sudden hearing loss accompanied by familial hyperlipidemia. Pure tone audiometry indicated intermediate frequency hearing loss in one ear. Laboratory tests showed abnormal lipid metabolism, and genetic examination identified a heterozygous mutation in theAPOA5 gene. Diagnosis: Sudden hearing loss; hypercholesterolemia. The patient responded well to pharmacological treatment. This paper aims to analyze and discuss thepotential connection between abnormal lipid metabolism and sudden hearing loss.

The role of a mobile hearing application in secondary care ENT (HAppENT).

OBJECTIVE: Sudden hearing loss is a common presentation to ENT. In the authors' practice, patients often wait many weeks for formal hearing testing. This study aimed to assess whether a tablet-based hearing test, hearTest, could aid clinical decision-making within secondary care ENT. METHOD: This was a multi-centre, prospective, non-randomised study to assess the feasibility, usability and accuracy of hearTest. RESULTS: In the sample, hearTest was shown to be an acceptable method of testing for hearing loss by both patients and clinicians. The 0.5-4 kHz range had an average clinical agreement rate of 95.1 per cent when compared with formal pure tone audiometry, deeming it an accurate test to diagnose hearing loss. CONCLUSION: The authors propose that hearTest can be used within ENT as a clinical decision support tool when manual audiometry is not immediately available. Within the authors' practice, hearTest is used to aid diagnosis and management of sudden sensorineural hearing loss.

Treatment outcomes for idiopathic sudden sensorineural hearing loss in dialysis patients.

Idiopathic sudden sensorineural hearing loss (ISSNHL) is challenging for both nephrologists and otolaryngologists treating patients undergoing dialysis. This single-center, retrospective, observational study investigated the treatment outcomes of patients with ISSNHL undergoing dialysis, enrolling 700 patients (47 undergoing and 653 not undergoing dialysis) diagnosed with ISSNHL between January 2005 and December 2021 at Asan Medical Center, Republic of Korea. To balance pre-existing clinical characteristics, 1:5 propensity score matching (PSM) was performed with the patients who were not undergoing dialysis. Treatment included high-dose systemic steroid therapy or intra-tympanic steroid injections. The pure tone average of the groups was compared before and 2 weeks and 2 months after treatment. The hearing-improvement degree was evaluated using Siegel's criteria. Before PSM, age, prevalence of diabetes or hypertension, initial hearing threshold at each frequency level (0.5, 1, 2, and 4 kHz), and treatment strategies exhibited significant between-group differences. However, in the PS-matched cohort, none of the confounders showed significant between-group differences. Two months after steroid treatment, the non-dialysis patient group demonstrated significantly higher average improvement in pure tone audiometry (P = 0.029) and greater percentage of complete response according to Siegel's criteria. This study suggests that treatment outcomes for ISSNHL are significantly poorer for patients undergoing than for those not undergoing dialysis.

Normal Weight Central Obesity is a Poor Prognostic Factor for Sudden Sensorineural Hearing Loss.

OBJECTIVES: To investigate the role of normal weight central obesity (NWCO) in the prognosis of sudden sensorineural hearing loss (SSNHL). METHODS: We retrospectively investigated 807 cases of SSNHL from January of 2008 to August of 2019 from the Department of Otorhinolaryngology at Kaohsiung Medical University Hospital in southern Taiwan. We analyzed the association between overweight and obesity, NWCO, and the prognosis of SSNHL. The demographic and clinical characteristics, audiometry results, and outcomes were also reviewed. RESULTS: The nonobese (body mass index [BMI] < 24 kg/m2) and overweight and obese groups (BMI ≥ 24 kg/m2) comprised 343 (42.50%) and 464 (57.50%) patients, respectively. The favorable prognosis rates in the nonobese and the overweight and obese groups were 45.48% and 45.91%, respectively, without a significant difference (P = .9048). Multivariate logistic regression revealed that BMI (adjusted odds ratio [aOR] = 1.00, 95% CI = 0.948-1.062, P = .9165) was not significantly associated with SSNHL recovery. The normal weight noncentral obesity (NWNCO) and NWCO groups comprised 266 (77.55%) and 77 (22.45%) patients, respectively, and had favorable prognosis rates of 48.50% and 35.06%, respectively. The difference between the groups was significant (P = .0371). Multivariate logistic regression analysis revealed that NWCO (aOR = 2.51, 95% CI = 1.292-5.019, P = .0075) was significantly associated with SSNHL recovery. CONCLUSIONS: NWCO may significantly affect the prognosis of SSNHL.

N-Acetylcysteine combined with prednisolone treatment shows better hearing outcome than treatment with prednisolone alone for patients with idiopathic sudden sensorineural hearing loss: a retrospective observational study.

OBJECTIVES: Internationally, corticosteroids are still the mainstay treatment for patients with idiopathic sudden sensorineural hearing loss (ISSHL). This is a retrospective monocentric study investing the impact of adding N-acetylcysteine (NAC) to prednisolone treatment on patients with ISSHL at a tertiary university otorhinolaryngology department. METHODS: 793 patients (median age 60 years; 50.9% women) with a new diagnosis of ISSHL from 2009 to 2015 were included in the study. 663 patients received NAC administration in addition to standard tapered prednisolone treatment. Univariate and multivariable analysis were performed to identify independent factors regarding negative prognosis of hearing recovery. RESULTS: Mean initial ISSHL and hearing gain after treatment in 10-tone pure tone audiometry (PTA) were 54.8 ± 34.5 dB and 15.2 ± 21.2 dB, respectively. In univariate analysis, treatment with prednisolone and NAC was associated with a positive prognosis of hearing recovery in the Japan classification in 10-tone PTA. In multivariable analysis on Japan classification in 10-tone PTA including all significant factors from univariate analysis, negative prognosis of hearing recovery were age > median (odds ratio [OR] 1.648; 95% confidence interval [CI] 1.139-2.385; p = 0.008), diseased opposite ear (OR 3.049; CI 2.157-4.310; p < 0.001), pantonal ISSHL (OR 1.891; CI 1.309-2.732; p = 0.001) and prednisolone alone without NAC treatment (OR 1.862; CI 1.200-2.887; p = 0.005). CONCLUSIONS: Prednisolone treatment combined with NAC resulted in better hearing outcomes in patients with ISSHL than treatment without NAC.

Relationship Between Serum ET-1, HDL-C, and sVCAM-1 and Hearing Loss in Patients with Sudden Deafness.

Vascular causes are most commonly associated with sudden sensorineural hearing loss (SSHL). This study was performed to determine the relationship between serum endothelin-1 (ET-1), high-density lipoprotein cholesterol (HDL-C), soluble vascular cell adhesion molecule-1 (sVCAM-1) levels, and the degree of hearing loss in patients with SSHL. Firstly, 60 SSHL patients were admitted to The First Hospital of Shanxi Medical University. In the same period, 60 healthy subjects matching the age and gender of SSHL patients were selected as the control group. Then, serum levels of ET-1, HDL-C, and sVCAM-1 were measured by enzyme-linked immunosorbent assay (ELISA). Next, the relationship between serum levels of ET-1, HDL-C, and sVCAM-1 with clinicopathological factors and their diagnostic and prognostic values were analyzed and evaluated. Serum ET-1 and sVCAM-1 were increased, and HDL-C was decreased in patients with SSHL. Serum ET-1 and sVCAM-1 were higher and HDL-C was lower in patients aged ≥ 45 years, or severe hearing loss patients (P < 0.05). ROC analysis determined that ET-1 (AUC = 0.839), HDL-C (AUC = 0.830), and sVCAM-1 (AUC = 0.865) had excellent diagnostic values. In addition, patients with low levels of ET-1 and sVCAM-1 and high levels of HDL-C had better hearing prognosis (P < 0.05). Abnormal serum ET-1, HDL-C, and sVCAM-1 in patients with SSHL are closely related to age, and degree of hearing loss, and perform diagnostic and prognostic values.

Efficacy of intratympanic steroid therapy for severe and profound sudden sensorineural hearing loss.

BACKGROUND: Intratympanic steroids (ITS) in treating sudden sensorineural hearing loss (SSNHL) have become more widespread. AIM: This study investigates whether ITS treatment provides additional benefits when combined with systemic steroids (SS) in patients with severe and profound SSNHL. MATERIALS AND METHODS: Patients diagnosed with severe and profound SSNHL were divided into two groups: SS group and SS combined with ITS group. Pure-tone audiometry was performed before and three months after treatment completion. The pure-tone average (PTA), frequency-specific hearing gains, and average values were compared between the groups. RESULTS: The study included 57 patients (27 SS, 30 ITS), with a mean age of 50.09 ± 15.56. Before treatment: SS PTA 84.40 ± 15 dB HL, ITS 87.50 ± 9.38 dB HL (p = 0.36). After treatment: SS 62.2 ± 23.13 dB HL, ITS 65.17 ± 12.19 dB HL (p = 0.55). Average hearing gain: SS 22.19 ± 13.81 dB HL, ITS 22.33 ± 12.24 dB HL (p = 0.96). Frequency-specific gains were similar (p > 0.05). SS group: 12 slight improvement, 10 no improvement, 3 partial, 2 complete recovery. ITS group: 23 slight improvement, 6 no improvement, 1 partial. CONCLUSION: In our study, combining ITS with SS treatment did not provide additional benefits in treating severe and profound SSNHL.

Efficacy of high dose systemic versus combined (systemic and intratympanic) corticosteroid therapy in idiopathic sudden sensorineural hearing loss: A prospective randomized trial and risk factor analysis.

The pathophysiology and the proper treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) are an ongoing subject of debate. Locally or systemic administered corticosteroids are the most accepted drugs of treatment in reference to ISSNHL (idiopathic sudden sensorineural hearing loss), however, no strong evidence nor guidelines regarding their effectiveness yet exists. In our prospective, randomized, controlled trial 78 participants were enrolled. Patients were randomly assigned based on the day of admission to two groups according to treatment: group SS (n = 43) received intravenous systemic methylprednisolone alone, and group CT (n = 35) received intratympanic dexamethasone + systemic methylprednisolone. The primary outcome was to compare the hearing outcomes between the treatment groups based on different, widely accepted categories (Siegel, Kanzaki, modified Siegel and PTA4 gain). In consideration of the secondary outcome, we examined the effect of the various risk factors on the hearing improvement. No differences were detected regarding hearing improvement between the two groups, based on any criteria [Siegel's criteria (p = 0.604); Kanzaki's criteria (p = 0.720); modified Siegel's criteria (p = 0.524) and PTA 4 gain (p = 0.569)]. However, several clinical factors such as vertigo (p = 0.039), or cardiovascular comorbidity (p = 0.02) and the severity of initial hearing loss (p = 0.033) were found to bear a significant impact upon the hearing outcome. To the best of our knowledge, this is the first randomized controlled trial comparing high dose systemic and combination corticosteroid therapy in ISSNHL patients. Our findings suggest coexisting cardiovascular comorbidity, vertigo and severity of the initial hearing loss may bear a significantly higher impact upon hearing improvement, than the additional intratympanic steroid administration. The presented trial was registered in the European Union Drug Regulating Authorities Clinical Trials Database (name: Combinated systemic and intratympanic steroid therapy in idiopathic sudden sensorineural hearing loss, No.: 2017-000658-20) and with the ethical approval of The National Institute of Pharmacy and Nutrition (OGYÉI) (protocol No.: 7621, on 2017.02.16.).

Importance of early objective auditory testing in the presentation of sudden sensorineural hearing loss in children.

BACKGROUND: Functional hearing loss can be due to an auditory manifestation of functional neurological disorder, previously known as conversion disorder. METHODS: This is a case series of 3 pediatric patients with a diagnosis of idiopathic SSNHL who ultimately were found to have functional neurological disorder. RESULTS: Average age was 12.7 years at presentation (range 10-14 years). All three patients underwent invasive interventions prior to their initial clinic visit. All patients demonstrated profound SNHL on behavioural audiogram, but normal otoacoustic emissions (OAE) and auditory brainstem response testing. With counselling, both patients demonstrated significant hearing improvement. CONCLUSIONS: Early use of OAE's in the workup of SSNHL can avoid unnecessary and potentially harmful therapies and expedite access to counselling services which may help lead to symptom resolution.

Prevalence of perilymphatic fistula in patients with sudden-onset sensorineural hearing loss as diagnosed by Cochlin-tomoprotein (CTP) biomarker detection: its association with age, hearing severity, and treatment outcomes.

PURPOSE: To determine the prevalence of perilymphatic fistula (PLF) in sudden-onset sensorineural hearing loss (SSNHL) patients by employing the Cochlin-tomoprotein (CTP) detection test, a specific diagnostic marker for perilymph. We also analyzed the clinical characteristics associated with hearing outcomes in this cohort. METHODS: A total of 74 eligible patients were prospectively enrolled. Following myringotomy, middle ear lavage (MEL) samples underwent the CTP test to identify perilymph leakage. Intratympanic dexamethasone (IT-DEX) therapy was administered, and hearing outcomes were assessed. Control groups comprised patients with chronic otitis media (n = 40) and non-inflammatory middle ears (n = 51) with concurrent MEL sample collection. RESULTS: CTP was positive in 16 (22%) patients. No control samples showed positive results. Multiple regression analysis indicated that age and pre-treatment hearing levels significantly contributed to the CTP value. We found a positive correlation between CTP values, age, and pre-treatment pure-tone averages. Notably, CTP values in SSNHL cases aged 60 and above were significantly higher than in those below 60 years. Patients with positive CTP had significantly worse recovery rates after IT-DEX treatment. CONCLUSION: This study is the first prospective investigation demonstrating a positive relationship between CTP values, age, and hearing severity in SSNHL, indicating that PLF might be the essential cause of SSNHL, particularly in the elderly. Our findings suggest that IT-DEX may be less effective for PLF-associated SSNHL. Future research could reveal that PLF repair surgery is a viable treatment strategy for SSNHL. This study was registered under the UMIN Clinical Trials Registry (UMIN000010837) on 30/May/2013.

Congruence and incongruence on the radiological and functional examination of inner ear hemorrhage.

BACKGROUND: Inner ear hemorrhage (IEH) is an increasingly recognized cochlear lesion that can cause sensorineural hearing loss (SNHL). Magnetic resonance imaging (MRI) is known to be the best imaging modality for clarifying the causes of SNHL and providing images that point to those causes. AIMS: Evaluate the lesional patterns in patients with presumed Inner ear hemorrhage (IEH) from radiological and functional aspects. MATERIAL AND METHODS: We retrospectively reviewed 10 patients performed in our institution from 2014 to 2020, with suspected labyrinthine hemorrhage based on radiological and functional examination. RESULTS: We included 8 patients with IEH and sensorineural hearing loss (SNHL). The median age was 55 years (range: 3 months - 78 years). The results from the MRI and functional tests were compared for each end-organ. Only three cases (37.5%) showed a correlation between signal abnormalities and dysfunction in the labyrinthine apparatus. CONCLUSIONS: In patients with SNHL inner ear hemorrhage needs to be ruled out in the differential diagnosis, so specific MRI sequences should be requested. It represents a way to a better understanding of the disorder and the variety of findings claim for a complete auditory and vestibular testing.

Idiopathic Labyrinthitis: Symptoms, Clinical Characteristics, and Prognosis.

BACKGROUND: Labyrinthitis is an inner ear disorder of unknown incidence, characterized by sudden hearing loss and concurrent vertigo. Cohort studies of patients diagnosed with labyrinthitis are nonexistent. This study aims to describe the clinical characteristics and prognosis of patients diagnosed with idiopathic labyrinthitis. METHODS: Patients with labyrinthitis in the absence of a clear viral, bacterial, or autoimmune pathogenesis were retrospectively identified from electronic patient files. Symptoms at presentation and results from vestibular testing were retrieved. The 9-item Vestibular Activity Avoidance Instrument, administered during follow-up interviews by telephone, was used to assess the presence of persistent balance problems and activity avoidance behavior. RESULTS: Sixty-one patients with idiopathic labyrinthitis were included. All patients had vestibular weakness at presentation. After a median of 61 months of follow-up (interquartile range 81), 72.5% of patients still experienced balance problems. Subjective hearing recovery only occurred in 20% of cases. CONCLUSION: Patients presenting in a tertiary dizziness clinic with idiopathic labyrinthitis have a poor prognosis for both hearing and balance function impairment. Prospective observational cohorts are required to establish objectifiable vestibular and audiological follow-up data.

Pregnant Patients with Sudden Sensorineural Hearing Loss: Treatments and Efficacy.

BACKGROUND: The aim of this study was to study the safety and effectiveness of oral and tympanic hormone injection in the treatment of sudden sensorineural hearing loss during pregnancy. METHODS: Data were collected via prospective method. A total of 102 pregnant women with sensorineural hearing loss as experimental group and another 102 patients of sensorineural hearing loss without pregnancy as control group were simultaneously included in the study. Pure tone audiometry test was examined at pre- and posttreatment in 1 week, 2 weeks, and 12 weeks. The experimental group received oral and tympanic hormones, while the control group was treated with the Clinical Practice Guideline: Sudden Hearing Loss (2019) of USA. Recovery rate and hearing gain were assessed by the Clinical Practice Guidelines. RESULTS: After treatment, the effects of the experimental group and the control group were compared at the 1st, 2nd, and 12th week after treatment. It was found that at the 12th week after treatment, the curative effect of the experimental group was significantly different from that of the control group, and the difference was statistically significant. CONCLUSION: The pregnant women with sensorineural hearing loss were more serious than nonpregnant women, and the treatment efficacies were worse than control group. For pregnancy patients with sudden deafness, oral steroids and tympanic cavity injection is an effective, safe first-line treatment options.

Hearing results with combination steroid therapy for sudden sensorineural hearing loss.

BACKGROUND: Sudden Sensorineural Hearing Loss was described by Mc. Cabe in 1979 and, since then, many authors have tried to define, explain and correctly treat this disease. The National Institute on Deafness and Other Communication Disorders defines it as sudden sensorineural hearing loss of at least 30 dB in three contiguous audiometric frequencies in a period of 72 hours. Among the therapeutic strategies, corticosteroids have been shown to have the greatest benefit due to their anti-inflammatory and anti-cellular stress effects. OBJECTIVE: To determine the hearing results with combined steroid therapy in patients with sudden sensorineural hearing loss (SSHL), according to the Siegel recovery criteria scale. METHOD: Study carried out in the otorhinolaryngology and head and neck surgery service of the Centro Médico Naval, Ciudad de México, where 150 patients diagnosed with SSHL and who received combined therapy with intratympanic dexamethasone and systemic prednisone were included. RESULTS: Therapeutic effectiveness was demonstrated by correlating therapeutic success in 82% of cases and therapeutic failure in 18% of cases, by correlating it with the Siegel recovery criteria scale. When evaluating the general average of the pure tone average levels at the beginning and 6 weeks after treatment, a statistically significant difference was obtained (p = 0.001). The average of the speech audiometry at the beginning and 6 weeks later had a statistically significant difference (p = 0.001). CONCLUSIONS: Initial combined steroid treatment for SSHL has been shown to have beneficial results according to Siegel recovery criteria scale.

ANTECENDENTES: La Hipoacusia Neurosensorial Súbita Idiopática fue descrita por Mc. Cabe en 1979 y, desde entonces, muchos autores han tratado de definir, explicar y tratar correctamente esta enfermedad. El Nacional Institute on Deafness and Other Communication Disorders la define como pérdida auditiva neurosensorial brusca de al menos 30 dB en tres frecuencias audiométricas contiguas en un periodo de 72 horas. Entre las estrategias terapéuticas, los corticosteroides han demostrado tener mayor beneficio por sus efectos antiinflamatorios y antiestrés celular. OBJETIVO: Determinar los resultados auditivos con la terapia de esteroides combinados en pacientes con hipoacusia neurosensorial súbita idiopática (HNSI), de acuerdo a la escala de criterios de recuperación de Siegel. MÉTODO: Estudio realizado en el servicio de otorrinolaringología y cirugía de cabeza y cuello del Centro Médico Naval, en Ciudad de México, en el que se incluyeron 150 pacientes con diagnóstico de HNSI y que recibieron terapia combinada con dexametasona intratimpánica y prednisona sistémica. RESULTADOS: Se demostró una efectividad terapéutica al correlacionar el éxito terapéutico en el 82% de los casos y un fracaso terapéutico en el 18% de los casos según la escala de criterios de recuperación de Siegel. Al evaluar el promedio general de los niveles de promedio de tonos puros al inicio y 6 semanas posterior al tratamiento se obtuvo una diferencia estadísticamente significativa (p = 0.001). El promedio de las logoaudiometrías al inicio y 6 semanas posterior al tratamiento tuvo una diferencia estadísticamente significativa (p = 0.001). CONCLUSIONES: El tratamiento combinado con esteroides de manera inicial para la HNSI ha demostrado tener resultados benéficos de acuerdo con la escala de criterios de recuperación de Siegel.
