CI-Diagnostics with special attention to neural function
Immanuel Kant already described how deafness divides people. It does not matter whether people are affected unilaterally or on both sides. Every form of hearing impairment has its own characteristics. In any case, speech understanding is limited or even canceled. The cochlear implant is the only form of hearing rehabilitation that offers the possibility of rehabilitating binaural hearing as an inner ear prosthesis in sensorineural disorders. Various conditions must be met in advance. In this workshop the special cochlear implant diagnostics will be discussed. The focus is on audiological functional diagnostics. The application and statement of various early auditory evoked potentials will be discussed and demonstrated. We are available to you in an interactive discussion in a team of engineer and doctor multidisciplinary.

Small animal audiometry - distorted product otoacustic emissions (DPOAE) and auditory brainstem response (ABR)
The electrophysiological and audiological measurements such as auditory brainstem responses (ABR) and distorted product otoacoustic emissions (DPOAE) are diagnostic methods measuring the performance of auditory pathway. ABR and OAE are used in clinical and in the basic research setting. During this workshop, we will demonstrate the technical aspects of the electrophysiological measurements in animals using rat as an example. The ABR measures synchronous activity of the auditory brainstem evoked by a short acoustic stimulus. A series of beeps ranging between 500 Hz and 32 kHz are presented to anesthetized animal. This signal induces neural activity in the auditory brainstem, recorded from electrodes on the skin surface. There are 5 identifiable ABR wave forms. Wave I represents the summated response from the spiral ganglion and auditory nerve while waves II-V represent responses from the ascending auditory pathway. DPOAEs are acoustic signals measured in the ear canal and generated by the outer hair cells in response to two simultaneously stimuli different frequency. In our experiments, frequencies between 2 kHz and 32 kHz. The DPOAE represents non-linear processes occurring in the healthy cochlea.

Vestibular diagnostics
There are predictable relationships between vestibular pathophysiology and tests that comprise contemporary vestibular diagnostics. The workshop will descibe each test in the balance function test battery, the diagnostic information it yields and how the tests correlate with each other to provide a complete diagnostic picture. The learning objectives of the vestibular diagnostic’s workshop include:
1. To help decide the appropriate vestibular test(s) to conduct to assist in better diagnostic outcome;
2. Describe the contribution VNG/ENG or posturographic testing makes to vestibular diagnostic assessment;
3. Describe how each of the vestibular assessments do (or do not) correlate with one another;
4. Describe how these relationships contribute to the creation of coherent diagnostic patterns.

Diagnosis of psychosomatic comorbidities
Psychiatric disorders such as depression, anxiety disorders or somatoform disorders are common and associated with severe impairment of patients’ quality of life. Diagnosis can be challenging, due to complex psychosomatic interactions, mimicked symptom presentations and heterogeneous expressions. Associated symptom clusters yield complex interactions between cognitive, affective, behavioural and somatic factors that occur against a background of genetic and environmental vulnerability. The present workshop gives an overview of common psychiatric syndromes, placing particular emphasis on heterogeneous symptom presentation. The aim is to sensitize ENT practitioners and psychologists to common symptom profiles and psychosomatic interactions.

Cochlear immunofluorescence
The unique tissue architecture enables visualization of cochlear morphology with a relatively little effort, especially when using fluorescent staining and epifluorescent microscopy. You will be introduced to a 30-minutes staining procedure using with fluorochrome-coupled phalloidin and DAPI. Phalloidin a seven amino acids peptide that binds filamentous actin (F-actin) and prevents its depolymerization, which makes it very useful in cell biology. All structures containing F-actin (such as cell walls or stereocillia) can be visualized by incubation with labeled phalloidin. DAPI is a synthetic, naturally fluorescent stain of DNA that binds between deoxyadenosine triphosphate (dATP) and deoxythymidine triphosphate (dTTP). Using both – phalloidin and DAPI – one can visualize the outer and inner hair cells, which are F-Actin rich, and differentiation between healthy and apoptotic/necrotic nuclei of all cells present in cochlea.
In addition to this, we will perform two-step, antigen-specific staining of cochlea. In the first step, we will use antibody recognizing myosin VIIa (expressed by sensory hair cells) and another antibody recognizing neurofilament-200 (expressed by cochlear spiral ganglion cells). In the second step, we will use fluorescently-labeled secondary antibodies that react with primary antibodies.
This workshop is intended for those who would like to have hands-on experience with fluorescent and immunofluorescent staining.
The read-out will be profimed with Evos FL (https://www.youtube.com/watch?v=cw5mKPM-fHQ).

Hearing aids
Hearing instruments have developed dramatically during the last two decades. Especially the introduction of digital signal processing has lead to many new processing approaches. Active feedback suppression algorithms enable more open fittings. Adaptive directional microphone systems improve speech intelligibility in noisy situations. Automatic analysis and classifica¬tion of the acoustical environment improve the performance in complex listening situations and facilitate the use of multi-memory hearing instruments. Even binaural signal processing now is emerging due to the wireless technologies now available. In this presentation, an overview over actual trends in amplification and their benefit for hearing impaired subjects and tinnitus patients will be given.

Tinnitus: diagnosis and treatment
Tinnitus is one of the most frequent symptoms encountered in ENT practice. Its diagnosis and treatment are challenging due to its multifactorial etiology as well as commonly encountered interactions with preceding or resulting affective comorbidities. This workshop describes factors thought to be involved in the etiology and maintenance of the phenomenon. Particular emphasis will be placed on medical-emotional interactions that may delay tinnitus and distress habituation. A brief overview of gold-standard diagnostic instruments will be given. Recommendations for treatment pathways will be given in accordance with current evidence-based treatment guidelines.

Cervical spine and hearing impairment
It is evident, that dysfunction of and trauma to the cervical spine and disorders of the temporo-mandibular joints may lead to hearing loss and tinnitus. The neurophysiologistic background has already been shown in the 90ies by Neuhuber and Pfaller. Shore et al have been investigating the relevance of the trigeminal system in the pathophysiology of tinnitus since more than 15 years. In this workshop the clinical and practical tools for these topics will be shown. This will include a demonstration of the anatomy and physiology, aspects of history, important diagnostic findings of the cervical spine and TMJ and special X-ray findings. The therapeutic approach with medicaments, physical and manual therapy will be discussed. A special issue will be the diagnostics of the somatosensoric tinnitus. Finally, a new and successful therapy for tinnitus will be demonstrated: local anaesthesia of the ganglion oticum. This workshop is practical with “hands on training” in the functional diagnosis of the mentioned structures. This workshop gives you practical access to the diagnostic and therapeutic management of hearing disorders in relation to the functional system of head and neck.
