Introduction This study was performed to assess identifiable abnormalities in tinnitus patients with normal hearing. Methods The medical records of subjective non-pulsatile tinnitus patients with normal hearing confirmed by conventional pure-tone audiometry who visited our tinnitus clinic between March 2020 and May 2022 were reviewed. The loudness discomfort level (LDL), extended high-frequency hearing loss (EHFHL), summating potential (SP)/action potential (AP) ratio, distortion product otoacou

Patients with co-occurring tinnitus and hyperacusis had more severe tinnitus distress. An LDL of ≤90 dB at two or more frequencies may be applicable to predict accompanying hyperacusis in subjects with tinnitus, and qEEG also provides more objective information.

BACKGROUND AND OBJECTIVES: We aimed to analyze treatment outcomes following different initial management approaches and confirm treatment regimens for acute low-tone sensorineural hearing loss (ALHL) that would yield the best results. SUBJECTS AND PURPOSE: We retrospectively analyzed the medical records of 106 patients with ALHL who visited a university hospital's otology clinic from March 2013 to June 2019. Pure-tone averages at the initial visit and at 2 and 4 weeks after the initial visit wer

Abstract Background Patients with tinnitus may have different severity levels of tinnitus distress. Visual analog scale (VAS) is a simple method to measure the extent of subjective distress caused by tinnitus. It includes ratings of tinnitus loudness, awareness, annoyance, and impact of tinnitus on life. Purpose The purpose of this study was to evaluate what led to different distress levels in patients with bilateral tinnitus by analyzing the relationships among all subscales of VAS scores for t

BACKGROUND: We aimed to analyze the patient characteristics in accordance with white matter lesions and confirm whether white matter lesions affect final treatment outcomes in idiopathic sudden sensorineural hearing loss. METHODS: Medical records of 126 patients treated for unilateral idiopathic sudden sensorineural hearing loss and who underwent magnetic resonance imaging of the brain at an otology clinic in a university hospital from 2013 to June 2019 were reviewed. The Fazekas scale was used

This study aimed to confirm the characteristics of auditory function alterations in tinnitus patients with concomitant decreased sound tolerance (ST) and provide insights for developing tailored therapeutic approaches. A retrospective analysis was conducted on patient records from a tertiary university hospital's tinnitus clinic between March 2020 and June 2023. Demographic attributes and audiological profiles were reviewed. Patients were categorized into Group 1 if loudness discomfort level tes

The findings highlight the SP/AP ratio in ECochG as a valuable biomarker for assessing clinical and psychological aspects of tinnitus, indicating its potential utility in tailoring treatment strategies. Elevated SP/AP ratios were associated with sleep disturbances, depression, attention problems, aural fullness, hyperacusis, and low-frequency hearing loss, suggesting a complex interplay between cochlear pathology and tinnitus perception. This study underscores the need for a nuanced understandin

We aimed to evaluate the impact of short-term tinnitus treatment on cognitive function and identify the effects of various treatment combinations on cognitive and tinnitus outcomes. A non-randomized prospective study was conducted with 32 tinnitus patients at a tertiary university hospital between May 2022 and May 2024. Patients received treatments, including neuromodulation, diuretics, gabapentin, selective serotonin reuptake inhibitors (SSRI), anxiolytics, muscle relaxants, hearing aids, and c

BACKGROUND: Transcranial random noise stimulation has previously been used to manage tinnitus. This study assessed the feasibility of adjuvant transcranial random noise stimulation with conventional steroid treatment for idiopathic sudden sensorineural hearing loss with or without tinnitus. METHODS: Prospective, randomized, single-blind study was conducted in Eulji University hospital. Twenty-four patients with idiopathic sudden sensorineural hearing loss were admitted for treatment between Marc

Congenital cholesteatomas are epithelial lesions that present as an epithelial pearl behind an intact eardrum. Congenital and acquired cholesteatomas progress quite differently from each other and progress patterns can provide clues about the unique origin and pathogenesis of the abnormality. However, the exact pathogenic mechanisms by which cholesteatomas develop remain unknown. In this study, key proteins that directly affect cholesteatoma pathogenesis are investigated with proteomics and immu

Despite a very strong correlation between the two thresholds, H3k and H24k showed clinically large LOAs. Therefore, it would be improper to substitute H24k for H3k in an individual requesting a hearing disability rating. However, since the overall means of the H3k and H24k samples were nearly equal, H24k can replace H3k for a mean comparison of results between studies. This result supports the 1995 Committee on Hearing and Equilibrium guideline.

INTRODUCTION: We aimed to investigate the clinical significance of the loudness discomfort level (LDL) test in tinnitus patients and its relationship with pure-tone audiometry, tinnitogram, and questionnaires. METHODS: We retrospectively reviewed the medical records of 320 tinnitus patients who visited a tertiary university hospital's tinnitus clinic and completed LDL tests between March 2020 and December 2022. Epidemiological data and psychoacoustic test results were collected. RESULTS: The LDL

Hearing impairment not only diminishes sound perception but also leads to various secondary disabilities; therefore, proper management is crucial for individual well-being and socioeconomic savings. This study establishes an expert consensus on the treatment of hearing impairment, primarily concentrating on hearing aids (HAs), to assist physicians. A modified nominal group technique was used to collect expert opinions about the management of hearing impairment with HAs. The expert panel consiste
