It is clear that the majority of adults with bilateral cochlear implants are much better at horizontal localization with two implants compared with one, but their abilities do not reach those of normal-hearing listeners. The localization results for children and for bimodal (cochlear implant in one ear, hearing aid in the other) listeners are less clear, with some improvement over monaural listening, but not for all subjects.[...]© Thieme Medical PublishersGet connected:Table of contents  |  Abstract  |  Full text (Source: Seminars in Hearing) Seminars in Hearing journals http://www.medworm.com/rss/comments.php?id=3354142 Thu, 11 Mar 2010 18:10:54 +0100 3354142 http://www.medworm.com/index.php?rid=3354141&cid=s_36622_161_f&fid=36622&url=http%3A%2F%2Fwww.thieme-connect.com%2FDOI%2FDOI10.1055%2Fs-0029-1246322 Semin Hear 2010; 31: 028-036DOI: 10.1055/s-0029-1246322ABSTRACTImplantable middle ear hearing devices (IMEHDs) were developed in an effort to improve on the limitations of traditional hearing aids. The last few years have seen significant advances in this technology with the emergence of several new devices, including fully implantable prostheses. As more patients are being implanted, experience with these devices has increased and refinements have been made. The indications also have expanded to include patients with mixed hearing loss in addition to those with pure sensorineural hearing loss, with application of the transducer to either the ossicles or the oval or round window. Fully implantable devices also are gaining ground, although most of these are relatively new and are still in t...

As satisfaction is related to expectations, if postfitting performance with the Baha matches or exceeds initial expectations, the patient may consider this management a success and have satisfaction with treatment outcome. In contrast, unrealistically high preoperative expectations for this management approach may result in dissatisfaction if performance falls short after the sound processor is fitted. The present study explores the relationship between prefitting expectations and postfitting satisfaction in a sample of 10 patients with acquired unilateral sensorineura...

BPPV is one of the most common causes of dizziness or vertigo, and almost 10% of the elderly population experiences BPPV. It is often self-limiting but can become chronic and recurrent with considerable effects on a person's quality of life. Most cases result from the migration of free-floating canalith particles into the posterior (more commonly) or horizontal (less commonly) semicircular canals, rendering them sensitive to gravity. Diagnosis of BPPV is based on a suggestive history and physical examination, and other tests are not normally required. Repo...

The subjective visual vertical (SVV) is a psychophysical measure of the angle between perceptual vertical and true (gravitational) vertical. The otoliths contribute to the estimation of the physical vertical orientation, and individuals with normal vestibular function align the SVV within 2 degrees of true vertical (0 degrees). Impaired SVV has been documented in patients with unilateral vestibular disorders. Most research has focused on measuring the static SVV (head upright and stationary); however, more recently, methods have been developed to measure the SVV during stimul...

Currently, two types of rotation tests are in clinical use: passive whole-body rotation where the stimulus is produced by a motorized chair, and active rotation where the stimulus is produced by voluntary head movements. In both methods, the frequency response of the vestibulo-ocular reflex (VOR) is determined by measuring the eye movements and comparing the head velocity with the slow-phase eye velocity. Rotation tests offer several advantages over other vestibular function tests in patients with bilateral caloric weakness, in young children, or in patients for whom VOR changes have to be assessed o...

The balance system is complex, which can make differential diagnosis of dizziness quite challenging. However, this complex system is organized anatomically in a variety of pathways, and some of these pathways have been documented. The vestibulo-ocular reflex (VOR) is one such pathway. Understanding the anatomy and physiology of the VOR facilitates our understanding of normal and abnormal eye movements, and research is advancing our understanding of the plastici...

This creates barriers for many patients who defer hearing and balance health care because they find the process cumbersome. Eliminating the need to see the physician first would remove a hurdle for the Medicare patient.

As primary care providers and gatekeepers to both medical and audiological services, physicians possess the influence and opportunity to encourage patients of all ages and their families to recognize, accept, and seek further testing and treatment for hearing and balance problems when they exist. It is critical that physicians who work with patients of all ages having audiological-related issues possess current knowledge of these topics so that they can make appropriate referrals to audiologists for further diagnosis and intervention.

In the 1970s, the first self-employed audiologists began practicing independently of medical and academic centers. Since that time, the number of audiologists choosing to enter private practice has increased significantly. Private practitioners have made significant contributions to the field, including advocacy, involvement in professional organizations, and increased recognition of the audiologist as a well-credentialed and skilled professional. In this article, current challenges of private practice are discussed, including recognition among the medical community and the general public, business and time management, education and recruitment of new p...

Changes in cochlear structures, whether from biological aging of the structures themselves or secondary to intrinsic and extrinsic influences that occur with the passage of time, result in hearing sensitivity loss. The outward expression of the underlying disorder is fairly consistent. That is, loss of function of cochlear hair cells and other structures consistently manifest hearing sensitivity loss and the consequent deficits in audibility. Age-related changes in auditory nervous system structures may also play a role in overall hearing capability, although the outward expression of the disorder is likely t...

Bess to the early detection of hearing loss in infants and children. Based on public health and educational policy, Bess challenged audiologists to view hearing screening as a responsibility that brought with it the need to develop screening tools that are effective in identifying hearing loss—whether for use with infants, preschoolers, or school-age children—and that adhere to important screening principles.

Occupational exposure to solvents or administration of clinically important drugs, such as aminoglycoside antibiotics and cisplatin, also can induce permanent hearing loss. The mechanisms by which these ototoxic insults cause auditory dysfunction are still being unraveled, yet they share common sequelae, particularly generation of reactive oxygen species, that ultimately lead to hearing loss and deafness. Individuals are frequently exposed to ototoxic chemical contaminants (e.g., fuel) and noise simultaneously in a variety of work and recreational environments.

The contribution of nonauditory centers in the pathogenesis and regulation of tinnitus is reinforced by studies showing that many patients have somatic tinnitus whereby movements and manipulations of the eyes, head, neck, jaw, and shoulder can modulate the loudness and pitch of their tinnitus. In most cases, the maneuvers lead to increases in tinnitus loudness or pitch rather than decreases. Our results indicate that most tinnitus patients experience only a modest change in loudness or pitch when performing these maneuvers. However,...

This means that the psychoacoustic attributes of tinnitus might be changed temporarily during forceful muscle contractions of the head, neck, and limbs; eye movements in horizontal or vertical axis; myofascial trigger points; cutaneous stimulation of the hand or fingertip region; electrical stimulation of the median nerve and hand region; finger movements; or orofacial movements or pressure applied to the temporomandibular joint.

However, most studies have found that hearing loss reduces the neural outputs from the damaged cochlea. These negative findings led to the hypothesis that tinnitus arises from aberrant neural activity in the central auditory system. Positron emission tomography imaging studies performed on tinnitus patients that could modulate their tinnitus provide evidence showing that the aberrant neural activity that gives rise to tinnitus resides in the central auditory pathway.

We make some suggestions regarding how electrical current might alter these patterns of neural activity. For example, if tinnitus were represented with periodic neural activity, then electrical stimulation would need to disrupt this periodicity. Some cases of cochlear electrical stimulation are reviewed that show the tinnitus can be reduced or eliminated with cochlear electrical stimulation although it varies across individuals.

Both functional imaging studies in patients and electrophysiological studies in animals suggest that hyperactivity in the central auditory system due to increased synchronicity may cause tinnitus. Targeted modulation of tinnitus-related cortical activity has been proposed as a promising new treatment. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive method that can focally modulate cortical activity. This technique has been used to diagnose and treat tinnitus. Single sessions of high-frequency rTMS over the temporal cortex have been used to suppress tinnitus transiently and could become a useful predictor for treatment outcome of epidural stimu...

Thus the activation of neuronal cell assemblies is chronically changed in patients with an ongoing tinnitus perception. We used magnetoencephalography to investigate these changes in a resting condition. There was an increase of synchronized activity in the gamma and delta frequency range together with a decrease in the α band. Manipulation of these cortical networks by means of neurofeedback therapy resulted in a reduction of tinnitus loudness and distress.

Increased neural spontaneous activity in the central auditory system found in animal models of tinnitus should have a basis in their chemistry. Most chemical studies so far have focused on neurotransmitters, by which neurons communicate with each other, because alteration of this chemistry could easily lead to abnormal neural activity that might be perceived as tinnitus. Although increased spontaneous activity has been observed in the hamster dorsal cochlear nucleus (DCN) a month after intense tone exposure, we did not find increased glutamate concentrations in the 3 layers of the hamster dorsal DCN at that time.

The premise on which these models are based is that chronic tinnitus is most likely a primitive hearing disorder. Because no evidence indicates that higher-order cognitive skills are required to experience tinnitus, it is also likely that animals such as laboratory rats can experience tinnitus. Chronic tinnitus in humans commonly emerges after peripheral auditory damage caused by exposure to loud sound, ototoxic agents, or aging. Tinnitus can be induced in animals using the same treatments. A significant advantage of using animals to study tinnitus is that the etiology of their disorder can be carefully controlled in a laboratory setting, a difficult ta...

Psychoeducational and psychosocial problems have been well documented in a large percentage of these children. However, audiologists remain concerned about the appropriate application of hearing technologies in children with these mild degrees of losses and the effectiveness of these technologies. Concerns generally center on which of these children should use hearing technology, which technologies are most effective, and how the technology should be fitted. Furthermore, audiologists are uncertain about when children should be fit with hearing technology. This review of hearin...

Children with unilateral or mild bilateral permanent hearing loss represent a substantial proportion of all children with hearing loss, and there are serious negative consequences for these children if they are not identified early and given appropriate help. Many children, particularly those with unilateral or mild bilateral hearing loss, acquire hearing loss after the newborn period. Although virtually all newborns are now screened for hearing loss before leaving the hospital, there are very few opportunities for periodic hearing screening after the newborn period.

Such exposure puts children at risk for developing noise-induced hearing loss (NIHL) and tinnitus. For more than 30 years, health policy agencies and numerous experts in hearing science have recommended teaching hearing-loss prevention practices to children in schools as a way to reduce the prevalence of NIHL. Despite these recommendations, basic hearing-loss prevention information that could prevent countless cases of NIHL remains conspicuously absent from most school curricula.

To meet that goal, this paper focuses on the relationship between the prevalence of noise-induced hearing loss, attitudes to noise and exposure, and how hearing protection use seems to be linked to cultural and socioeconomic factors. Results of a series of studies point to attitudes as one explanatory factor. Additionally, the experience of hearing symptoms such as tinnitus and noise sensitivity increases the likelihood that adolescents and young adults will choose to wear earplugs when attending clubs or discotheques.

The Code of Ethics of both the American Academy of Audiology and the American Speech-Language and Hearing Association incorporate the elements of ethical practice for audiologists. To appreciate the added requirements of professionalism, one needs to understand fully such concepts as public trust, conflict of interest, and personal versus corporate integrity. A few short courses teach the concepts of business ethics; however, there are few required courses that teach ethical concepts to audiologists. The lack of such didactic information does not remove the audiologist from the r...

One can be prepared by developing and following a practice compliance program. There are steps you can take to prepare for a Medicare audit. Prepayment and postpayment audits will be discussed as well as appealing your carrier's overpayment claim. It is important to understand what Medicare considers fraud and recognize reasons why Medicare claims are rejected. There is no need to panic if you receive a letter from your Medicare carrier requesting review of specific patient charts or a letter requesting a refund due to overpayment. A Medicare audit should be taken seriously. With good record keeping and adhering to Medicare guidelines, going ...

The expectations they may have for their treatment, their personal issues, and even their desire to receive the recommended treatment must all be recognized as essential components to the care provided. In this article, the author presents three case scenarios in which the audiologist's treatment recommendations do not match what the patients are willing to accept. Ultimately, patients follow their own judgment and make their own decisions. Here suggestions are offered for guiding patients to recognize alternative views. Ultimately, it is their decisions that must be honored-even if erroneous.[...]Copyright © 2...

Traditional self-report methods used to measure loudness and loudness discomfort are not suitable for use with animals because the animals cannot provide subjective responses about the magnitude of an internal psychological perception. Instead, reaction time (RT) measures have been used in animals to estimate loudness perception. In the present study, the authors demonstrate that RTs are shorter at moderate and high sound levels in canaries of a strain with a hereditary high-frequency hearing loss than in normal canaries, indicating increased loudness. As far as we know, this is the first report of hyperacusis in...

Two types of DPOAE measures were evaluated: (1) the distortion product- (DP-) gram measured with fixed primary levels as a function of frequency, and (2) DPOAE input/output (I/O) functions for a range of primary levels between 45 and 70 dB sound pressure level (SPL) at 1000, 2000, and 4000 Hz.

In theory, this hypothetical gain process is plastic and can be systematically modified and recalibrated. The idea of an adaptive auditory gain mechanism is a fundamental concept in the treatment of both tinnitus and hyperacusis with tinnitus retraining therapy (TRT). This notion, however, has gone virtually untested. The hypothesis of this research is that judgments of loudness provide a functional index of chronic auditory gain. Further, chronic auditory gain can be manipulated either upward or downward in a controlled way by prolonged reduction or enhancement in the levels of background sound to which a ...

Sizable secondary treatment benefits, namely, incremental shifts in loudness discomfort levels (LDLs) and expansion of the auditory dynamic range (DR) for loudness, have been reported for tinnitus patients who use noise generators (NGs) for ST in TRT. The primary questions addressed in this study are (1) Then hearing-impaired tinnitus patients using amplified environmental sound for their ST also achieve significant secondary treatment benefits and, if so, (2) are these secondary effects of similar magnitude to those measured for tinnitus patients using NGs f...

Follow-up LDLs subsequent to tinnitus retraining therapy (TRT) were used to predict hyperacusis subsequent to treatment. Pretreatment and TRT follow-up audiometric thresholds and LDLs were analyzed for a group of 68 tinnitus patients who self-reported sound tolerance complaints and a group of 58 tinnitus patients who denied sound tolerance problems. A logistic regression model was implemented to determine which of the eight audiological measures (i.e., four threshold and four LDL measures) were essen...

Pretreatment and TRT follow-up audiometric threshold, loudness discomfort level (LDL), and dynamic-range (DR) data are documented for (1) a group of 68 tinnitus patients who presented with primary complaints of sound intolerance, and (2) a second group of 70 patients who reported only tinnitus (and no sound tolerance problems). TRT-related increases in sound tolerance are (1) due to increases in LDLs and occur independently of changes in audiometric threshold, which were invariant with treatment; (2) statistically significant in tinnitus ...
