BACKGROUND: Manières disease (MD) is a chronic inner ear disease characterized by recurrent vertigo and fluctuation in auditory symptoms. Vertigo spells have a sudden onset and are difficult for patients to handle. Therefore, treating a patient with MD is still a challenge for clinicians. AIMS: This study aims to analyse the short-term effects of intratympanic dexamethasone (ITD) on the various symptoms of unilateral MD. MATERIALS AND METHODS: The study comprised 27 patients with unilateral MD and severe vertigo who failed medication therapy...

BACKGROUND: Chronic unsteadiness is a common complaint at vestibular clinics. Bilateral vestibulopathy (BVP) is a major cause of chronic unsteadiness but is often overlooked. Although diagnostic criteria for BVP have been established by the Barany Society, isolated vertical canal hypofunction can remain undiagnosed. Recently, the video head-impulse test has enabled clinicians to assess vertical semicircular canal function at clinics. OBJECTIVE: This study aimed to compare the features of isolated bilateral posterior semicircular canal hypofunction (IBPH) with those of BVP diagnosed based on the Barany criteria...

BACKGROUND: The cochlea contains a robust biological clock associated with auditory function, exhibiting diurnal sensitivity to noise or ototoxicity. OBJECTIVES: We examined the relationship between disrupted circadian rhythm and altered expression of circadian clock genes in patients with sudden sensorineural hearing loss (SSNHL) and explored whether the circadian clock genes serve as prognostic biomarkers. MATERIAL AND METHODS: Twelve patients with SSNHL were enrolled study group...

BACKGROUND: The plasma atherogenic index (AIP) is used as an indicator of cardiovascular risk. Abnormal lipid levels have been shown to potentially contribute to facial nerve inflammation observed in Bell's palsy. This study sought to investigate the association of AIP with the severity and prognosis of Bell's palsy. MATERIAL AND METHODS: AIP is calculated using the equation Log (triglyceride [mg/dL]/high-density lipoprotein cholesterol [mg/dL]). The study was conducted prospectively on 79 patients diagnosed with Bell's palsy...

BACKGROUND: Diazepam, a gamma-aminobutyric acid type A receptor agonist, is classified as a vestibular suppressant and is effective in treating acute vertigo. However, its effects on vestibular compensation (VC) remain unclear. OBJECTIVES: We examined the effects of continuous administration of diazepam on the frequency of spontaneous nystagmus (SN) after unilateral labyrinthectomy (UL) as an index of the initial process of VC in rats. MATERIALS AND METHODS: Diazepam was continuously administered at doses of 3...

Background: Short array cochlear implant is indicated as rehabilitation in patients with severe to profound deafness, especially when there is cochlear ossification. In these cases, with reduced intracochlear patency, total insertion becomes more difficult, requiring the use of this type of electrode (15 mm). Few studies have been published to evaluate auditory performance, presenting controversial audiological results. Aims/Objectives: To report the speech perception of users of cochlear implants (CI) with short array...

BACKGROUND: Systemically administered steroids are widely utilised for hearing preservation therapies. More recently, steroids have been administered to achieve hearing protection after cochlear implant surgery. Currently there is a lack of understanding as to which administration route offers most therapeutic efficacy, local or systemic administration. Paramount to this are observations in animal studies that systemic administration following implantation offers hearing protection and reduced cochlear fibrosis, despite observations that perilymphatic levels are up to 10-fold higher after local administration in non-implanted cochleae...

BACKGROUND: Ménière's disease (MD) mainly refers to the endolymphatic hydrops in membranous labyrinth of the inner ear. Application of the mass spectrometry-based proteomics techniques has not been applied in the field of MD. OBJECTIVES: To search for potential differential proteins to identify the disease biomarkers and reveal disease bioinformatics-related mechanisms through applying protein technology to analyze the expression changes of peripheral blood mononuclear cells (PBMCs) in sporadic MD patients...

BACKGROUND: As a low-cost, portable, handheld air pressure generation tool not requiring a ventilation tube, the EFET01 device has shown clinical effectiveness for intractable Ménière's disease (MD) patients in Japan. However, no animal studies have investigated changes in inner ear pressure (PI ) when applying this device. OBJECTIVE: To determine the PI properties in response to middle ear pressure therapy (MEPT) induced by the EFET01 in guinea pigs. MATERIAL AND METHODS: In seven healthy guinea pigs, bi-phasic pressure pulses from -5 to 12 cm H2 O were delivered to the external ear canal and transmitted to the middle and inner ear cavities with an intact tympanic membrane...

BACKGROUND: Although immune checkpoint inhibitors (ICIs) are approved for the treatment of recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC), the response to ICIs remains unclear. AIMS/OBJECTIVES: To summarize the clinical outcomes of patients with HNSCC treated with nivolumab (Nivo) in our institution, and provide a basis for research on biomarkers that can predict the efficacy of ICIs. MATERIAL AND METHODS: Forty-four patients with R/M HNSCC who received Nivo (2017-2022) were retrospectively analysed...
