OBJECTIVE: Psychotic disorders and intelligence deficiencies are no longer contraindications for cochlear implantation regarding the revised German guidelines from May 2012. This article aims to evaluate the outcome of patients with severe psychiatric comorbidities. Therefore the database of the Cochlear Implant Center of the University Hospital of Heidelberg was investigated. STUDY DESIGN: Retrospective case review. METHODS: We present three patients who received a cochlear implant (CI) despite a serious psychiatric disorder...

CONCLUSIONS: The detection of cytomegalovirus (CMV) and herpes simplex virus-1 (HSV-1) genome in perilymph of patients with negative serology or clinical history for congenital infections supports the hypothesis that Herpesviridae, even after acquired postnatal infections, could remain in latent phase in the spiral ganglion and damage the cochlea by a possible subsequent reactivation. Further studies are needed to identify the markers of such reactivation. OBJECTIVE: To identify the presence of certain viral species in the endolabyrinthic fluid of deaf patients with non-congenital infection...

Lemierre's syndrome is a rare disorder that is characterized by anaerobic organisms inducing a thrombophlebitis of the internal jugular vein (IJV) following a course of oropharyngeal infection. It often occurs in young and healthy patients. Clinicians continuously misinterpret early symptoms until infection disseminates systematically and life-threatening sepsis transpires. We report the case of a 58-year-old female developing Lemierre's syndrome accompanied by invasive ventilation support and a profound deafness requiring the implementation of a cochlear implant...

Cochlear implants are mechanical devices used for patients with severe sensory-neural hearing loss, which has an inner magnet. It is proven that 1.5 Tesla magnetic resonance imaging (MRI) scanners are safe to use in patients with cochlear implant. In our patient, the authors aim to introduce a rare complication caused after a 1.5 Tesla MRI scanning and the management of this situation; the reversion of the magnet of the implant without displacement and significance of surgery in management.

Even as recently as the mid-1980s, many experts in otology and auditory science thought that restoration of useful hearing with crude and pervasive electrical stimulation of the cochlea was a fool's dream. The esteemed Prof. Rainer Klinke from Frankfurt (Figure 1) was among the chorus of critics, asserting in 1978 that "from a physiological point of view, cochlear implants will not work." Many others made similar categorical statements.

OBJECTIVE: To study the aspects of the quality of life (QoL) on which music has an impact in adult cochlear implant (CI) users. METHODS: Thirty adult CI users aged between 18 and 81 years old with a wide range of patient characteristics and musical backgrounds participated in the study. Six focus group discussions about music in everyday life were conducted and data were analysed using template analysis based on the QoL model of the World Health Organisation Quality of Life BREF questionnaire...

Jérôme J Servais, Karl Hörmann, Elisabeth Wallhäusser-Franke
Perceptive and receptive aspects of subjective tinnitus like loudness and tinnitus-related distress are partly independent. The high percentage of hearing loss in individuals with tinnitus suggests causality of hearing impairment particularly for the tinnitus percept, leading to the hypothesis that restoration of auditory input has a larger effect on tinnitus loudness than on tinnitus-related distress. Furthermore, it is assumed that high levels of depression or anxiety prevent reductions of tinnitus loudness and distress following restoration of activity in the cochlea...

Clear visualization of the round window niche (RWN) and round window membrane (RWM) through the facial recess using standard posterior tympanotomy approach is a prime requisite for the surgeon. Moreover, even with the traditional cochleostomy approach, proper identification of RWN is essential for accurate localization of promontory cochleostomy site.

Heather A Kreft, Andrew J Oxenham
Auditory enhancement is the phenomenon whereby the salience or detectability of a target sound within a masker is enhanced by the prior presentation of the masker alone. Enhancement has been demonstrated using both simultaneous and forward masking in normal-hearing listeners and may play an important role in auditory and speech perception within complex and time-varying acoustic environments. The few studies of enhancement in hearing-impaired listeners have reported reduced or absent enhancement effects under forward masking, suggesting a potentially peripheral locus of the effect...

A Büchner, L Gärtner
Twenty years ago, cochlear implants (CI) were indicated only in cases of profound hearing loss or complete deafness. While from today's perspective the technology was clumsy and provided patients with only limited speech comprehension in quiet scenarios, successive advances in CI technology and the consequent substantial hearing improvements over time have since then resulted in continuous relaxation of indication criteria toward residual hearing. While achievements in implant and processor electronics have been one key factor for the ever-improving hearing performance, development of electro-acoustic CI systems-together with atraumatic implantation concepts-has led to enormous improvements in patients with low-frequency residual hearing...

OBJECTIVE: The primary objective of this study was to assess the effect of electric and acoustic overlap for speech understanding in typical listening conditions using semidiffuse noise. DESIGN: This study used a within-subjects, repeated measures design including 11 experienced adult implant recipients (13 ears) with functional residual hearing in the implanted and nonimplanted ear. The aided acoustic bandwidth was fixed and the low-frequency cutoff for the cochlear implant (CI) was varied systematically...

OBJECTIVE: Current spread is a substantial limitation of speech coding strategies in cochlear implants. Multipoles have the potential to reduce current spread and thus generate more discriminable pitch percepts. The difficulty with multipoles is reaching sufficient loudness. The primary goal was to compare the loudness characteristics and spread of excitation (SOE) of three types of phased array stimulation, a novel multipole, with three more conventional configurations. DESIGN: Fifteen postlingually deafened cochlear implant users performed psychophysical experiments addressing SOE, loudness scaling, loudness threshold, loudness balancing, and loudness discrimination...
