Diagnostics and Treatments with Mechanical Rotation Chairs - what have we learned after more than ten years of use?
09-10, 07:30–08:00 (Europe/Istanbul), Equilibrium 2

<p>Description: Mechanical Rotation Chairs (MRCs) have proven very successful with both diagnostics and treatments of patients with Benign Paroxysmal Positional Vertigo (BPPV). Previous studies have shown that an MRC offer superior diagnostics by being more sensitive (and thereby accurate) than traditional BPPV diagnostics. With canalith repositioning maneuver (CRM) refractory BPPV patients (retractable BPPV cases, multi-canal BPPV, cupulolithiasis subtype BPPV), MRCs provide successful treatment with overall success rates of 90+ percentages. Even very retractable BPPV cases (defined by a need of more than ten MRC treatments) can also, to a large extent, be treated successfully by individually targeted treatments.</p> <p>Outcome Objectives: The primary objective is to describe results from ten years of clinical experience and research with two separate MRCs on BPPV diagnostics and -treatments. A total of twelve (seven originating from own Tertiary University Hospital based outpatient clinic) clinical trials evaluating both BPPV diagnostics and -treatments with MRCs will be included.</p> <p>Background: Patients with BPPV may be seen, diagnosed, and treated by many different health care professionals, e.g. General Practitioners or Physiotherapists (primary sector), ENT Specialists (secondary sector) or Neurotologists at highly specialized University Hospital-based centers (tertiary sector). Despite an a priori good prognosis for successful treatment, ten to twenty percent of patients diagnosed with BPPV cannot be treated successfully by means of traditional CRMs carried out on an examination bed. Therefore, several new therapeutic modalities like bi- axial MRCs have been developed.</p>
<p>Increase knowledge of the pros and cons with the use of MRCs. Especially important to make peers aware of the superior diagnostic properties of MRCs as the path to successfull treatment of BPPV starts by doing the best possible diagnostics.</p>

<p>I received my Medical degree from Aarhus University, Denmark in 2004 and I was certified as an ENT Specialist in 2012. Since 2014 I have been the Head of the Audiovestibular Department at Aalborg University Hospital, Denmark as well as an Associate Professor of Otolaryngology at Department of Clinical Medicine, Aalborg University, Denmark. I have been a Board member of the Danish Vestibular Society since 2017, President from 2020-2023 and Vice President from 2017-2019 and from 2024 and onwards. Primary areas of interest include inner ear diseases, audiology, neurotology, and Bone Anchored Hearing Aids. Work areas include an oto-surgery, neurotology, medical audiology, and research. The primary focus of my research is clinical research of inner ear diseases within the audiological- and vestibular subspecialties. Current research areas primarily include diagnostics and treatment of Benign Paroxysmal Positional Vertigo (BPPV) with Mechanical Rotation Chairs, video Head Impulse Testing, Wide Band Tympanometry in diagnostics of inner ear diseases, telemedicine in audiology and Implants for Bone Anchored Hearing Systems.</p>

<p>I am an ENT specialist (MD) with a PhD in Audiology. My clinical and academic focus is on vestibular disorders, auditory pathologies, and the differential diagnosis of vertigo. My PhD thesis explored cVEMP responses using air and bone conduction stimuli in various types of hearing loss. I aim to bridge the gap between clinical otolaryngology and advanced vestibular diagnostics, and I continue to contribute to interdisciplinary research in neurotology and balance disorders.</p>
