Intralabyrinthine schwannoma (ILS) is a rare benign tumor that affects the ends of cochlear and vestibular nerves. In a majority of the cases, it occurs with unilateral progressive sensorineural hearing loss. Less frequent symptoms include tinnitus, imbalance, vertigo, or fullness. The advent of magnetic resonance imaging allows early diagnosis and enables an appropriate therapeutic protocol. This report describes a case of intravestibular schwannoma, with fluctuating hearing loss and intractable vertigo, treated with intratympanic gentamicin...

OBJECTIVE: In this study, we evaluated the prognostic value of the Dizziness Handicap Inventory (DHI) and the Tinnitus Handicap Inventory (THI) in patients with unilateral sudden sensorineural hearing loss (SSNHL). MATERIALS AND METHODS: In total, 101 patients with unilateral SSNHL (44 women, 57 men), who were admitted and treated at our institution between December 2012 and June 2014, were included in the study. All patients completed the questionnaires for DHI and THI during their admission and were treated with bed rest and oral methylprednisolone (1 mg/kg, which was eventually tapered)...

OBJECTIVE: Methotrexate is a dihydrofolate reductase enzyme inhibitor with very high selectivity, and it is an antiproliferative folic acid antagonist used for the treatment of autoimmune diseases. In this study, our objective was to evaluate the effect of intratympanic Methotrexate application in the inner ear. METHODS: This study was planned as an animal study. This study performed in a tertiary referral center. 24 healthy female rats were used in our study. They were separated into three groups...

Corticosteroid treatment has been considered the most effective treatment modality for sudden sensorineural hearing loss so far. Application route of corticosteroids may vary. We have designed a prospective randomized case-controlled clinical trial to evaluate the effectivenesses of the different application routes of steroids in the treatment of SSHL. Thirty-five patients were distributed randomly to two groups which were treated with either 'oral' or 'intratympanic' corticosteroids. Intratympanic steroid administration was performed three times every other day transtympanically...

OBJECTIVES/HYPOTHESIS: We compared the clinical characteristics between acute low- and high-frequency hearing loss (LF and HF, respectively) patients, and the efficacy of three different treatment protocols (systemic steroids, intratympanic steroid injection, and combination therapy). STUDY DESIGN: Prospective, randomized controlled study. METHODS: A total of 111 patients diagnosed with LF or HF were treated on an outpatient basis. Each group was randomly divided into three equal subgroups based on therapy: oral steroid, intratympanic dexamethasone injection (IT), and combination therapy...

MATERIALS AND METHODS: It is a retrospective case review study. Twenty five patients who had definite Meniere's disease and had either selective window application or weekly IT gentamicin were included into the study.

BACKROUND: Only few therapeutic options exist for patients with refractory sudden idiopathic sensorineural hearing loss (SISHL). Little is known about the efficacy of second-line therapies. Rheopheresis seems to be an effective therapeutic possibility. METHODS: Between 2012 and 2015, 106 patients with SISHL were enrolled in the study, of whom 52 were refractory to initial treatment. As salvage therapy, these patients were offered either 3 sessions of rheopheresis (33 pts) or intratympanic steroid treatment through MicroWick application (19 pts)...

PURPOSE: The goal of this retrospective study was to investigate the differential diagnosis of endolymphatic hydrops in patients with Meniere's disease (MD) symptoms by using magnetic resonance imaging (MRI) with intravenous injection of gadolinium chelate and delayed acquisition. MATERIAL AND METHOD: Two hundred patients (133 women, 67 men; mean age=67.2±11 ([SD] years) with unilateral MD underwent MRI at 3-T, between 4.5 and 5.5hours after intravenous administration of gadoterate meglumine at a dose of 0...

OBJECTIVE: To evaluate the effects of selective serotonin re-uptake inhibitors (SSRIs) on Meniere's disease (MD) on patients who have both MD and generalized anxiety disorder. MATERIALS AND METHODS: All patients were evaluated with neurotologic examination, videonystagmography, audiological tests, and inner ear magnetic resonance imaging. Characteristic history and the evaluation of the patients' vertigo attacks during the attacks were the primary criteria for the diagnosis of MD...

The purpose of this experimental study was to investigate the protective role of intratympanically administered dexamethasone on the inner ears of rats that were exposed to streptomycin ototoxicity. Twenty-four adult Wistar albino rats were separated into 4 groups: Group 1 (only streptomycin), Group 2 (only intratympanic dexamethasone), Group 3 (streptomycin and intratympanic dexamethasone), and Group 4 (streptomycin and intratympanic saline). All rats were evaluated with distortion product otoacoustic emissions (DPOAE) tests before the start of treatment and on the day it ended...

Enlarged vestibular aqueduct (EVA) syndrome is a common congenital inner ear malformation characterized by a vestibular aqueduct with a diameter larger than 1.5 mm, mixed or sensorineural hearing loss that ranges from mild to profound, and vestibular disorders that may be present with a range from mild imbalance to episodic objective vertigo. In our study, we present the case of a patient with unilateral enlarged vestibular aqueduct and bilateral endolymphatic hydrops (EH). EH was confirmed through anamnestic history and audiological exams; EVA was diagnosed using high-resolution CT scans and MRI images...

INTRODUCTION: Meniere's disease (MD) is a disease of the inner ear that presents itself with repeated episodes of vertigo (96.2%), tinnitus (91.1%), and sensorineural hearing loss (87.7 %). In this article we sought to assess the effects of intratympanic (IT) injections of dexamethasone on definite cases of MD using electrocochleography (ECOG). MATERIALS AND METHODS: In this hospital-based case series in 36 patients, we measured audiometric values and ECOG in all patients before, 1 month and 6 months after 4-mg/mL IT injections of dexamethasone...

Liposome nanocarriers (LPNs) are potentially the future of inner ear therapy due to their high drug loading capacity and efficient uptake in the inner ear after a minimally invasive intratympanic administration. However, information on the biocompatibility of LPNs in the inner ear is lacking. The aim of the present study is to document the biocompatibility of LPNs in the inner ear after intratympanic delivery. LPNs with or without gadolinium-tetra-azacyclo-dodecane-tetra-acetic acid (Gd-DOTA) were delivered to the rats through transtympanic injection...

OBJECTIVE: Many studies over the last decade showed favorable outcomes with intratympanic (IT) steroid treatment, alone as salvage treatment or in combination with conventional systemic therapy (ST). However, in severe to profound sensorineural hearing loss resistant to ST, the optimal infusion mode, the type and concentration of the solution, the preferable drug, its total amount, and the duration and fractionation of the treatment are still debated. Aim of the study was to investigate the feasibility and the outcomes of a direct and constant IT delivery of dexamethasone (DEX) by means of a new indwelling catheter...

This article reviews recent aspects of diagnostics, differential diagnostics and evidence in systemic and local therapy of idiopathic, sudden, sensorineural hearing loss (ISSHL). Since a number of disorders can be accompanied by sudden hearing loss a meaningful and targeted diagnostic strategy is of utmost importance. An important differential diagnosis of sudden hearing loss are intralabyrinthine schwannomas (ILS). The incidence of ILS is probably significantly underestimated. This may be due to the lack of awareness or lack of explicit search for an intralabyrinthine tumor on MRI or an inappropriate MRI technique ('head-MRI' instead of 'temporal bone-MRI' with too high slice thickness) for the evaluation of sudden hearing loss...

OBJECTIVE: Aminoglycosides, used to combat with life-threatening infections, have a substantial risk of hearing loss. Nigella sativa is an annual herbaceous plant and used for treatment of many diseases for ages. We aimed to investigate the protective role of intratympanic nigella sativa oil against gentamicin induced hearing loss in an animal model. METHODS AND MATERIALS: Twenty eight guinea pigs were randomly divided into four groups: i-control, ii- Intratympanic nigella sativa oil (IT-NSO), iii- Intraperitoneal gentamicin (IP-G) and iv- Intraperitoneal gentamicin and intratympanic nigella sativa oil (IP-G + IT-NSO)...
