Cholesteatoma is a serious otolaryngologic condition that to date remains an important problem and poses a challenge to otolaryngologists around the world. To improve the approach pertaining to the diagnosis and management of middle ear cholesteatoma, clear, clinically applicable, and useful definition and classification of cholesteatoma are required. This review aimed to evaluate the current and most accepted descriptions and opinions concerning cholesteatoma. A review of the literature concerning different definitions and classifications of cholesteatoma was used in the preparation of the Cholesteatoma Guidelines, a project implemented by the European Academy of Otology - Neuro-otology...

The current paper reports on a patient with recurrent rotational vertigo and persistent dizziness and imbalance lasting several weeks, who underwent extensive neuro-otological and radiological examinations. Pathological findings initially included right-sided benign paroxysmal positional vertigo (BPPV), persistent horizontal spontaneous nystagmus (SPN) to the left, and a pathological bedside and video head impulse test (HIT) on the left. The pathological HIT on the left and the SPN to the left indicated a central origin...

OBJECTIVE: Our aim was to identify the role of the investigators' knowledge of the patient's history of vestibular symptoms (PVH) in the clinical evaluation of the bedside head-impulse test (bHIT). We hypothesized that this knowledge will reduce uncertainty and improve bHIT accuracy when compared to quantitative analysis of the vestibulo-ocular reflex by video head-impulse test (vHIT). METHODS: We looked for changes in the clinical assessment of the bHIT in 594 consecutive patients before and after taking PVH...

The objective of the present study was to elucidate the frequency of causes underlying the development of dizziness and vertigo in the patients seeking advice and care at an outpatient healthcare facility. A total of 590 patients with complaints of dizziness and vertigo were examined. It was found out that the peripheral disorders of the vestibular analyzer were the most frequent causes of dizziness and vertigo in the majority of the examined patients. These conditions were documented to occur in more than 65% of the patients...

OBJECTIVE: We hypothesised that chronic vestibular symptoms (CVS) of imbalance and dizziness post-traumatic head injury (THI) may relate to: (i) the occurrence of multiple simultaneous vestibular diagnoses including both peripheral and central vestibular dysfunction in individual patients increasing the chance of missed diagnoses and suboptimal treatment; (ii) an impaired response to vestibular rehabilitation since the central mechanisms that mediate rehabilitation related brain plasticity may themselves be disrupted...

The optimal method for diagnosing cochleovestibular neurovascular compression syndrome(CNVC)remains controversial, and the aim of this study is to develop a standard diagnostic instrument for the condition. The clinical features of 53 sides of 50 patients with a combination of vertigo, tinnitus, and/or hearing loss were retrospectively evaluated. The following five clinical features were evaluated and given a score of 1 or 0:1)a long history of recurrent vertigo, tinnitus, or hearing loss;2)neurological findings related to positional vertigo, nystagmus, tinnitus, or hearing loss;3)neuro-otological findings involving tinnitus, audiometry, or vestibular testing;4)auditory brainstem response(ABR)evaluation with the detection of a low 25-75% II wave amplitude on the contralateral side and delayed interpeak latency in the I-III or I-V waves(usually low II wave amplitude combined with double peaks and a wide-based form)during ABR evaluation using 80 and 90dB clicks;and 5)the detection of vascular contact with the eighth cranial nerve on magnetic resonance imaging-constructive interference in steady state or air computed tomography imaging...

PURPOSE OF REVIEW: Functional dizziness is the new term for somatoform or psychogenic dizziness. The aim of this study is to review arguments for the new nomenclature, clinical features, possible pathomechanisms, and comorbidities of functional dizziness. RECENT FINDINGS: The prevalence of functional dizziness as a primary cause of vestibular symptoms amounts to 10% in neuro-otology centers. Rates of psychiatric comorbidity in patients with structural vestibular syndromes are much higher with nearly 50% and with highest rates in patients with vestibular migraine, vestibular paroxysmia, and Ménière's disease...

Chronic subjective dizziness(CSD) was defined as persistent nonvertiginous dizziness or subjective unsteadiness. Patients are hypersensitivity to motion stimuli, such as head movement and motion of objects in the visual surrounding, and have difficulty with precise visual tasks. The concept of CSD was first proposed by Staab and Ruckenstein, which indicates relationships between chronic dizziness and acute vestibular or psychiatric disorders, including neuro-otologic type, psychiatric type or interactive type...

Bilateral sudden onset hearing loss and vestibular dysfunction due to metastatic carcinoma of the internal auditory canal (IAC) on both sides is an extremely rare occurrence. This is a challenging case in neuro-otology that is difficult to relieve by medical support, and spontaneous compensation by vestibular rehabilitation is minimal. The spread of tumor cells to the cerebrospinal space indicates poor prognosis. We present a patient with stage-III gastric carcinoma who experienced sudden hearing loss and severe imbalance...

Dizziness and vertigo are among the most common symptoms to bring a patient to a neurologist. Because symptoms are often vague and imprecise, a systematic approach is essential. By categorizing vestibular disorders based on timing, triggers, and duration, as well as through focused oculomotor and vestibular examinations, the vast majority of neuro-otologic diagnoses can be made at the bedside. Here the authors discuss historical and examination pearls for the most common neuro-otologic disorders.

Treating tinnitus with the resources offered in hospitals can become necessary for patients suffering from complex tinnitus if a high symptom severity, usually accompanied by a corresponding psychosomatic comorbidity, is present. For such costly therapies, for example, the neuro-otologic psychosomatic tinnitus therapy (NPT) examined here, the long-term effect is particularly important; however, reliable catamnesis studies for inpatient treatments are not yet available. Data from 169 (from a total of 327 contacted) inpatients suffering from complex tinnitus were analysed here...

In most dizzy patients a limited selection of bedside tests, together with the history, is adequate to establish a differential diagnosis and select the next diagnostic and therapeutic procedures. A set of basic bedside tests that should be applied in every patient with vertigo or imbalance allows identifying: (1) patients who need immediate referral for further assessment and treatment; (2) patients with nonthreatening disorders for which treatment can be started without more detailed testing; (3) patients with benign paroxysmal vertigo, in whom a detailed work-up is not required and who can immediately be treated with an appropriate particle-repositioning maneuver; and (4) patients who need a comprehensive neuro-otologic and neurologic work-up...

The management of sporadic vestibular schwannoma (VS) has evolved in the last decades. The aim of this study was to analyse the evolution in surgical outcomes of VSs operated by a neurotological team between 1990 and 2006 by different approaches. A monocentric retrospective review of medical charts of 1006 patients was performed. In order to assess eventual changes and progress, the 17-years period was divided in three periods, each one comprehending 268 VS (1990-1996), 299 VS (1997-2001), and 439 VS (2002-2006)...

BACKGROUND: Balance problems are caused by multiple factors and often lead to falls and related fractures, bringing large socio-economic costs. The complexity of balance control mechanisms, the lack of medical expertise, and the absence of specialised equipment contribute to the delayed or incorrect diagnosis and management ofthese patients. Advances in computer science have allowed the development of computer systems that support clinical diagnosis and treatment decisions based on individualised patient data...

OBJECTIVE: Perverted downbeat head-shaking nystagmus (pdHSN) has been considered a sign of central pathology. Two hypotheses have been advanced as the mechanisms of pdHSN without proper validation. This study aimed to elucidate the mechanism of pdHSN. METHODS: Eighteen patients with pdHSN due to central lesions were subjected to analyses of their oculographic characteristics. The peak velocity, temporal features including the duration and time constant (TC), rotational axis of pdHSN were analyzed...

INTRODUCTION: Cervical vestibular evoked myogenic potentials (cVEMP) can assess the integrity of the inferior vestibular nerve thereby promising to be a useful tool in the audiological test battery to diagnose vestibular schwannoma. OBJECTIVE: To ascertain the utility of cVEMP in diagnosis of vestibular schwannoma in conjunction with the ABR and to evaluate whether the size of lesion has any effect on the cVEMP measures. METHODS: Case-files of 15 known cases of vestibular schwannoma whose pure tone audiometry, auditory brainstem response (ABR), cVEMP and radiological investigation findings were available, were included in the study...
