We report an extremely rare case of hearing aid silicone impression material as a foreign body in the middle ear. Symptoms of the patient were otorrhea and vertigo after taking of a mold impression on his only hearing ear, and the symptoms mimicked chronic otitis media. A temporal bone CT scan revealed foreign body material in the middle ear and Eustachian tube. An intact canal wall mastoidectomy with a facial recess approach and type IV tympanoplasty was performed to remove the silicone impression material...

OBJECTIVE: Otitis media (OM) with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) is a novel concept of ear disease that is characterized by progressive mixed or sensorineural hearing loss with occasional systemic involvement. Considering the accumulating knowledge about the characteristics of and treatment for auditory dysfunction in OMAAV, the objective of this study was to investigate the vestibular function and symptoms of patients with OMAAV. STUDY DESIGN: Retrospective chart review...

A 26-year-old woman developed symptoms of acute toxicity during cyclosporine (CsA) therapy for graft-versus-host disease prophylaxis. The standard regimen included CsA in a dose of 1.5 mg/kg (120 mg) every 12 h, but, as a medication error, she received a high dose of 500 mg of oral CsA. After 2 h, she developed nausea and vomiting and, subsequently, flushing, chest tightness, tremor and vertigo. Laboratory and clinical examinations revealed high blood CsA concentrations (1000 ng/mL after 12 h) with a mild increase in blood pressure...

Introduction. Vestibular schwannomas (VS) are benign tumours of the vestibular nerve and can lead to hearing loss, tinnitus, vertigo, facial palsy, and brainstem compression. Audiovestibular diagnostic tests are essential for detection and treatment planning. Methods. Medline was used to perform a systematic literature review with regard to how audiovestibular test parameters correlate with symptoms, tumour size, and tumour location. Results. The auditory brainstem response can be used to diagnose retrocochlear lesions caused by VS...

Vestibular migraine (VM) is one of the most common causes of episodic vertigo. We reviewed the results of multiple vestibular function tests in a cohort of VM patients who were diagnosed with VM according to the diagnostic criteria of the Barany Society and the International Headache Society and assessed the efficacy of each for predicting the prognosis in VM patients. A retrospective chart analysis was performed on 81 VM patients at a tertiary care center from June 2014 to July 2015. Patients were assessed by the video head impulse test (vHIT), caloric test, vestibular-evoked myogenic potentials (VEMPs), and sensory organization test (SOT) at the initial visit and then evaluated for symptomatic improvement after 6 months...

BACKGROUND: The experience of the medical team, interdisciplinarity, quality of the physician-patient relationship, sensible use of modern technology, and a sound knowledge about the long-term results of observation and interventions all influence treatment quality in patients with vestibular schwannomas. OBJECTIVES: Compilation of findings regarding the results of observation and microsurgical treatment of patients with these tumors. Deduction of strategies for the medical management from these data...

BACKGROUND: This is an updated version of the original Cochrane review published in Issue 12, 2011. Phantom limb pain (PLP) is pain that arises in the missing limb after amputation and can be severe, intractable, and disabling. Various medications have been studied in the treatment of phantom pain. There is currently uncertainty in the optimal pharmacologic management of PLP. OBJECTIVES: This review aimed to summarise the evidence of effectiveness of pharmacologic interventions in treating PLP...

A 59-year-old man developed a sudden onset of vertigo and nausea, and after a few hours, he could not swallow at all. On admission, neurological examination revealed severe dysphagia associated with other transient and mild neurological deficits, including left facial paresis, and hypesthesia in the right side of his body. MRI with diffusion weighted imaging showed a hyperintense signal lesion at the left rostral medial region of the medulla, prompting the diagnosis of an acute medial medullary infarction. His facial paresis and hypesthesia disappeared within 2 weeks...

INTRODUCTION: Cochlear implantation is an increasingly common procedure in the treatment of severe to profound sensorineural hearing loss (SNHL) in children and adults. It is often performed as a day-case procedure. The major drive towards day-case surgery has been from a logistical, economical and societal perspective, but we also speculate that the patient's quality of life (QoL) is at least equal to inpatient surgery if not increased as a result of rapid discharge and rehabilitation...

INTRODUCTION: Intrameatal cochleovestibular neurovascular conflict is a rare condition with specific clinical and therapeutic implications. Although surgery is commonly indicated in other neurovascular conflicts, for this subset of patients there is little evidence to guide treatment decisions. Moving from a case description, we performed a review of the literature on this topic in order to systematically present the best available evidence to guide clinical decisions. MATERIALS AND METHODS: We performed a literature review on reported cases of surgically treated intrameatal anterior inferior cerebellar artery (AICA) - cochleovestibular nerve (CVN) neurovascular conflict, analyzing preoperative clinical data, surgical techniques, and outcomes...

This article investigates the processing of vestibular information by interpreting current experimental knowledge in the framework of predictive coding. We demonstrate that this theoretical framework give us insights into several important questions regarding specific properties of the vestibular system. Particularly, we discuss why the vestibular network is more spatially distributed than other sensory networks, why a mismatch in the vestibular system is more clinically disturbing than in other sensory systems, why the vestibular system is only marginally affected by most cerebral lesions, and whether there is a primary vestibular cortex...

Ideally, vestibular pharmacotherapy is intended, through specific and targeted molecular actions, to significantly alleviate vertigo symptoms, to protect or repair the vestibular sensory network under pathologic conditions, and to promote vestibular compensation, with the eventual aim of improving the patient's quality of life. In fact, in order to achieve this aim, considerable progress still needs to be made. The lack of information on the etiology of vestibular disorders and the pharmacologic targets to modulate, as well as the technical challenge of targeting a drug to its effective site are some of the main issues yet to be overcome...

OBJECTIVE: To investigate the correlation between rapid bedside triple test and caloric test. METHOD: We reviewed clinical records of 313 consecutive patients presenting with vertigo at our ear-nose-throat clinic.RESULTS of bedside vestibular tests in all patients were compared with caloric test. The sensitivity, specificity, and positive and negative predictive values for the triple test relative to caloric test were calculated. RESULTS: Compared with the caloric test results, the sensitivity, specificity, positive predictive value(PPV), and negative predictive value(NPV) of the triple test were 65...

Bow hunter's syndrome (BHS), also known as rotational vertebral artery (VA) occlusion syndrome, is a rare yet treatable type of symptomatic vertebrobasilar insufficiency resulting from mechanical occlusion or stenosis of the VA during head and neck rotation or extension. The symptoms of BHS range from transient vertigo to posterior circulation stroke. The underlying pathology is dynamic stenosis or compression of the VA by abnormal bony structures with neck rotation or extension in many cases, such as osteophyte, disc herniation, cervical spondylosis, tendinous bands or tumors...

Rotational vertebral artery occlusion (RVAO) or bow hunter's syndrome most commonly affects the C1-2 level due to its importance in regulating rotational movement. We present a 50-year old man who had undergone several prior sub-axial cervical spine operations with increasing neck pain and severe symptoms of vertebrobasilar insufficiency with bi-directional head rotation. Dynamic cerebral angiography demonstrated complete occlusion of left vertebral artery during head rotation to the right, and complete occlusion of the right vertebral artery during head rotation to the left...
