To present the incidence of vestibular schwannoma (VS) in Denmark, compare with that previous periods, and discuss real VS.Prospective registration all diagnosed VS a population 5.1 to 5.2 million, during 6 years from January 1996 through December 2001. Incidence this period was compared 3 periods (July 1976 June 1983 [first period], July 1990 [second 1995 [third period]).In 1996-2001 period, 542 cases were diagnosed, representing mean 17.4 VS/1 million inhabitants per year. Of these, 227...

The incidence of diagnosed sporadic unilateral vestibular schwannomas (VS) has increased, due primarily to more widespread access magnetic resonance imaging.To present updated epidemiological data on VS incidence, as well patient age, hearing acuity, tumor size, and localization at diagnosis for the last 4 decades in an unselected population, with emphasis developments recent years.From 1976 2008, 2283 new cases were registered a national database covering 5.0 5.5 million inhabitants....

Abstract BACKGROUND: Reports on the natural history of tumor growth and hearing in patients with a vestibular schwannoma (VS) are almost exclusively short-term data. Long-term data needed for comparison results surgery radiotherapy. OBJECTIVE: To report long-term occurrence loss 156 diagnosed an intracanalicular VS managed conservatively. METHODS: In this longitudinal cohort study, diagnostic follow-up magnetic resonance imaging audiometry were compared. RESULTS: After 9.5 years, had...

Objective: Reports on the epidemiology of vestibular schwannoma (VS) indicate an increase in diagnosed cases, often based selected materials over a limited period time. This report presents prospective 40-year epidemiological data from unselected national cohort all patients with VS Denmark since 1976. Study-design: Data gender, age, tumor localization and size registered during 1976–2015 were retrieved. Results: 3637 new cases period. The annual number increased 14 1976 to 193 2015. Mean...

Abstract Aim: To evaluate hearing changes during ‘wait and scan’ management of patients with vestibular schwannoma. Subjects: Over a 10-year period, 636 have prospectively been allocated to management, annual magnetic resonance scanning audiological examination. Results: At the time diagnosis, 334 (53 per cent) had good speech discrimination better than 70 cent; at end observation this latter percentage was 31 cent. In 17 cent patients, diagnosis 100 these, 88 still period. However, in even...

The aim of the present study was to evaluate long-term hearing during "wait and scan" management vestibular schwannomas.During a 33-year period, from 1976 2008, 1,144 patients with schwannoma were allocated observation by wait scan policy, annual magnetic resonance imaging audiologic examination. Two complete pure-tone speech discrimination audiograms available for 932 patients. In 900 (97%), period at least 1 year. 377 (40%), time 5 years, in 102 (11%), 10 years.At diagnosis, 491 (53%)...

Cochlear implantation is a safe procedure in experienced hands, as the rate of severe complications below 2%. Complications differ between children and adults, transient disequilibrium/vertigo most common complication, followed by wound infection, haematoma/oedema chorda tympani syndrome. An international consensus on reporting proposed, high degree variability occurs literature, which precludes an overview necessary for adequate patient information incentives aimed at prevention.To report...

Repeated and deliberate practice is crucial in surgical skills training, virtual reality (VR) simulation can provide self-directed training of basic to meet the individual needs trainee. Assessment learning curves procedures pivotal understanding acquisition best-practice implementation organization training.To explore VR mastoidectomy effects different sequences with aim proposing optimal training.A prospective trial a 2 × design was conducted at an academic teaching hospital. Participants...

Abstract Background Childhood otitis media with effusion is a common disease and link to allergic diseases has been suggested. Objective To investigate the association between atopic diagnosed according strict objective case definitions by age 6 years. Methods We evaluated 291 children in 6th year of life from Copenhagen Prospective Studies on Asthma (COPSAC) 2000 birth cohort. Otitis was based tympanometric evaluation. Asthma, eczema, allergic‐ non‐allergic rhinitis prospectively...

Objectives/Hypothesis Cognitive load theory states that working memory is limited. This has implications for learning and suggests reducing cognitive (CL) could promote skills acquisition. study aims to explore the effect of repeated practice simulator‐integrated tutoring on CL in virtual reality (VR) mastoidectomy simulation. Study Design Prospective trial. Methods Forty novice medical students performed 12 procedures Visible Ear Simulator: 21 completed distributed with blocks spaced time...

Objectives: To study the impact of (re)habilitation strategy on speech-language outcomes for early, cochlear implanted children enrolled in different intervention programmes post implant.Methods: Data relate to a total 130 representing two pediatric cohorts consisting 94 and 36 subjects, respectively. The had speech language following implantation, i.e. standard habilitation vs. auditory verbal (AV) intervention. Three tests were applied covering areas receptive productive vocabulary...

During the last 26 years annual number of diagnosed vestibular schwannomas (VS) has been increasing. The aim this study is to describe and analyse increase. Since 1976, 1446 new cases VS have at authors’ centre. Special focus was on age diagnosis, localization size tumour. tumour registered as either intrameatal or with largest extrameatal diameter. increased from in 1976 101 2001. tumours decreased a median 35 mm 1979 10 In first large giant dominated, contrast recent which small dominated....

This paper reports data on the spontaneous course of hearing in 156 patients with purely intracanalicular vestibular schwannomas. The mean pure tone average (PTA) was 51 dB HL and speech discrimination score (SDS) 60% at diagnosis. risk a significant subsequent loss (>or=10 PTA or >or=10% SDS) 54% during 4.6 years observation. Patients normal diagnosis had significantly smaller loosing hearing. observation not related to age, gender, diagnostic tumor size, tumor- induced expansion internal...

Conservative treatment of acute otitis media may lead to more complications. This study evaluates changes in incidence, the clinical and microbiological findings, complications outcome mastoiditis children a country employing conservative guidelines treating media.All admitted (0-15 years) diagnosed with during period from 1998 2007 eastern Denmark (population 2.2 million) were identified.
