OBJECTIVES: We aimed to assess the clinical significance of the intensity of transcutaneous vagus nerve stimulation (tVNS) in chronic tinnitus. MATERIALS AND METHODS: Four sessions of tVNS were performed over a 2-week period for 24 patients with unilateral, non-pulsatile chronic tinnitus. The cavum, cymba, and tragus were sequentially stimulated to the maximal sensory thresholds. One month later, after the four sessions, the level of tinnitus distress and changes in stimulus intensity were assessed...

OBJECTIVE: To provide family physicians with an evidence-based and practical approach to managing patients with tinnitus. SOURCES OF INFORMATION: MEDLINE was searched for English-language tinnitus guidelines and reviews. All such articles published between 1980 and 2016 were reviewed, with most providing level II and III evidence. MAIN MESSAGE: Tinnitus affects more than 40% of Canadians at least once in their lifetimes, most commonly older adults...

During the past several years, the rapid development of neuroimaging techniques has contributed greatly in the noninvasive imaging studies of tinnitus. The aim of the present study was to explore the brain anatomical alterations in patients with right-sided unilateral pulsatile tinnitus (PT) in the early stage of PT symptom using voxel-based morphometry (VBM) analysis. Twenty-four patients with right-sided pulsatile tinnitus and 24 age- and gender-matched normal controls were recruited to this study. Structural image data preprocessing was performed using VBM8 toolbox...

Schneiderian papillomas (ISP) of the middle ear are uncommon conditions, with only 45 cases published within literature. They are locally aggressive tumours, with a high rate of recurrence and associated malignancy. We present a rare case of a 53-year-old man presenting with unilateral pulsatile tinnitus, otorrhoea, aural fullness, pruritis and hearing loss. Angiography was employed to exclude a glomus tumour and the patient underwent a modified radical mastoidectomy. Tissue samples confirmed a histological diagnosis of ISP of the middle ear...

OBJECTIVES: Finding the underlying cause for pulsatile tinnitus can be challenging. We aimed to determine the incidence of arteriovenous shunts, i.e., arteriovenous malformations (AVMs) or dural arteriovenous fistulas (dAVFs), in patients referred for catheter angiography (digital subtraction angiography [DSA]). Furthermore, we assessed which clinical features were predictive for the presence of such a lesion. STUDY DESIGN AND METHODS: Fifty-one patients with pulsatile tinnitus, who were referred to us for DSA to exclude an arteriovenous shunt, were enrolled, prospectively...

PURPOSE: This aimed to evaluate the prevalence and extent of bilateral sigmoid sinus dehiscence (SSD) and to explore the presence of idiopathic intracranial hypertension (IIH) in patients with unilateral pulsatile tinnitus (PT) with CTA/V. METHODS: Sixty PT patients (52 females; 40.4 ± 11.6 years [20-72]) who underwent CTA/V and 30 non-PT patients (27 females; 38.4 ± 14.7 years [12-62]) were enrolled in this study. The primary outcome measure was the radiographic presence of SSD...

OBJECTIVE: The objective of this research was to investigate the possible relationship between tinnitus and certain bony inner ear structures using computed tomography (CT). MATERIALS AND METHODS: This was a prospective, controlled, double-blind study. The subjects of the study were divided into the following three groups: group 1 (G1), patients with unilateral sensorineural hearing loss (SNHL) and unilateral non-pulsatile tinnitus in the same ear; group 2 (G2), patients with normal hearing and unilateral non-pulsatile tinnitus; and group 3 (G3), healthy volunteers with neither tinnitus nor hearing loss...

Unilateral pulsatile tinnitus (PT) was proved to be a kind of disease with brain functional abnormalities within and beyond the auditory network (AN). However, changes in patterns of the lateralization effects of PT are yet to be established. Relationship between the AN and other brain networks in PT patients is also a scientific question need to be answered. In this study, we recruited 23 left-sided, 23 right-sided PT (LSPT, RSPT) patients and 23 normal controls (NC). We combined applied independent component analysis and seed-based functional connectivity (FC) analysis to investigate alteration feature of the FC of the AN by using resting-state functional magnetic resonance imaging (rs-fMRI)...

OBJECTIVE: To highlight a case from 1960 connecting endolymphatic sac tumour and von Hippel-Lindau disease. CASE REPORT: In 1960, a 24-year-old woman presented with unilateral hearing loss, pulsatile tinnitus and a mass visible on otoscopy. The patient underwent surgical biopsy, which was complicated by haemorrhage, and ultimately resulted in death. At autopsy, a destructive temporal bone neoplasm with cystic and papillary architecture was observed that had eroded into the otic capsule...

Abnormal neural activities can be revealed by resting-state functional magnetic resonance imaging (rs-fMRI) using analyses of the regional activity and functional connectivity (FC) of the networks in the brain. This study was designed to demonstrate the functional network alterations in the patients with pulsatile tinnitus (PT). In this study, we recruited 45 patients with unilateral PT in the early stage of disease (less than 48 months of disease duration) and 45 normal controls. We used regional homogeneity (ReHo) and seed-based FC computational methods to reveal resting-state brain activity features associated with pulsatile tinnitus...

BACKGROUND: About 5-15% of people in the Western world will suffer from an extended period of tinnitus during their lifetime. This is often a non-treatable, disabling disorder. Tinnitus can be classified as pulsatile or non-pulsatile. Pulsatile tinnitus can be caused by a treatable neurovascular compression. CASE DESCRIPTION: Here we describe two patients, a 68-year old woman and 40-year old man suffering from pulsatile tinnitus and hemifacial spams due to neurovascular compression of the facial and acoustic nerve in the anterior cranial fossa...

OBJECTIVE: Previous studies demonstrated altered regional neural activations in several brain areas in patients with pulsatile tinnitus (PT), especially indicating an important role of posterior cingulate cortex (PCC). However, few studies focused on the degree of functional connectivity (FC) of this area in PT patients. In this study, we will compare the FC of PCC in patients affected with this condition and normal controls by using resting-state functional magnetic resonance imaging (fMRI)...

Previous resting-state functional magnetic resonance imaging (rs-fMRI) studies have shown that neurological changes are important findings in vascular pulsatile tinnitus (PT) patients. Here, we utilized rs-fMRI to measure the amplitude of low-frequency fluctuations (ALFF) in forty patients with unilateral PT and forty age-, gender-, and education-matched normal control subjects. Two different frequency bands (slow-4, 0.027-0.073 Hz, and slow-5, 0.010-0.027 Hz, which are more sensitive to subcortical and cortical neurological signal changes, resp...

OBJECTIVE: To investigate the impact of cochlear implantation on tinnitus suppression, characteristics, localization, and duration. DESIGN: A cochlear implant (CI) recipient-focused postal questionnaire survey. STUDY SAMPLE: The questionnaire was posted, with consent, to 100 adults who had received a unilateral CI at the RNTNEH between 1988 and 1999. All adults spoke English as their first language and were postlingually deafened. Sixty-eight adults (38 female, 29 male, one unspecified) aged 31-80 years (mean 61 years) completed and returned the questionnaire without interview...

While pulsatile tinnitus (PT) and dural arteriovenous fistula (DAVF) are not rarely associated, the finding of a conductive hearing loss (CHL) in this clinical picture is unusual. Starting from a case of CHL and PT, diagnosed to be due to a DAVF, we analyzed relationship between intracranial vascular abnormalities and inner ear fluids. DAVF was treated with endovascular embolization. Following this, there was a dramatic recovery of PT and of CHL, confirming their cause-effect link with DAVF. We critically evaluated the papers reporting this association...

BACKGROUND: Although air cells within temporal bone may play an important role in the transmission of pulsatile tinnitus (PT) noise, it has not been studied systematically. PURPOSE: To evaluate the difference in temporal bone pneumatization between PT patients with sigmoid sinus diverticulum and/or dehiscence (SSDD) and healthy people. MATERIAL AND METHODS: A total of 199 unilateral persistent PT patients with SSDD and 302 control subjects underwent dual-phase contrast-enhanced CT (DP-CECT), to assess the grade of temporal bone pneumatization in each ear...
