Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.
Electrical waves in the CEREBRAL CORTEX generated by BRAIN STEM structures in response to auditory click stimuli. These are found to be abnormal in many patients with CEREBELLOPONTINE ANGLE lesions, MULTIPLE SCLEROSIS, or other DEMYELINATING DISEASES.
Surgical insertion of an electronic hearing device (AUDITORY BRAIN STEM IMPLANTS) with electrodes to the cochlea nucleus in the BRAIN STEM rather than to the inner ear as in COCHLEAR IMPLANTATION.
Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.
Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.
A general term for the complete loss of the ability to hear from both ears.
Partial hearing loss in both ears.
The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).
Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.
An autosomal dominant inherited disorder (with a high frequency of spontaneous mutations) that features developmental changes in the nervous system, muscles, bones, and skin, most notably in tissue derived from the embryonic NEURAL CREST. Multiple hyperpigmented skin lesions and subcutaneous tumors are the hallmark of this disease. Peripheral and central nervous system neoplasms occur frequently, especially OPTIC NERVE GLIOMA and NEUROFIBROSARCOMA. NF1 is caused by mutations which inactivate the NF1 gene (GENES, NEUROFIBROMATOSIS 1) on chromosome 17q. The incidence of learning disabilities is also elevated in this condition. (From Adams et al., Principles of Neurology, 6th ed, pp1014-18) There is overlap of clinical features with NOONAN SYNDROME in a syndrome called neurofibromatosis-Noonan syndrome. Both the PTPN11 and NF1 gene products are involved in the SIGNAL TRANSDUCTION pathway of Ras (RAS PROTEINS).
An autosomal dominant disorder characterized by a high incidence of bilateral acoustic neuromas as well as schwannomas (NEURILEMMOMA) of other cranial and peripheral nerves, and other benign intracranial tumors including meningiomas, ependymomas, spinal neurofibromas, and gliomas. The disease has been linked to mutations of the NF2 gene (GENES, NEUROFIBROMATOSIS 2) on chromosome 22 (22q12) and usually presents clinically in the first or second decade of life.
Tumor suppressor genes located on the long arm of human chromosome 17 in the region 17q11.2. Mutation of these genes is thought to cause NEUROFIBROMATOSIS 1, Watson syndrome, and LEOPARD syndrome.
Design of patient care wherein institutional resources and personnel are organized around patients rather than around specialized departments. (From Hospitals 1993 Feb 5;67(3):14)
Children with mental or physical disabilities that interfere with usual activities of daily living and that may require accommodation or intervention.
Facilities which provide nursing supervision and limited medical care to persons who do not require hospitalization.

Inferior colliculus responses to multichannel microstimulation of the ventral cochlear nucleus: implications for auditory brain stem implants. (1/10)

Multichannel techniques were used to assess the frequency specificity of activation in the central nucleus of the inferior colliculus (CIC) produced by electrical stimulation of localized regions within the ventral cochlear nucleus (VCN). Data were recorded in response to pure tones from 141 and 193 multiunit clusters in the rat VCN and the CIC, respectively. Of 141 VCN sites, 126 were individually stimulated while recording responses in the CIC. A variety of CIC response types were seen with an increase in both electrical and acoustic stimulation levels. The majority of sites exhibited monotonic rate-level types acoustically, whereas spike rate saturation was achieved predominantly with electrical stimulation. In 20.6% of the 364 characteristic frequency aligned VCN-CIC pairs, the CIC sites did not respond to stimulation. In 26% of the 193 CIC sites, a high correlation was observed between acoustic tuning and electrical tuning obtained through VCN stimulation. A high degree of frequency specificity was found in 58% of the 118 lowest threshold VCN-CIC pairs. This was dependent on electrode placement within the VCN because a higher degree of frequency specificity was achieved with stimulation of medial, central, and posterolateral VCN regions than more anterolateral regions. Broadness of acoustic tuning in the CIC played a role in frequency-specific activation. Narrowly tuned CIC sites showed the lowest degree of frequency specificity on stimulation of the anterolateral VCN regions. These data provide significant implications for auditory brain stem implant electrode placement, current localization, power requirements, and facilitation of information transfer to higher brain centers.  (+info)

Electrical stimulation of the midbrain for hearing restoration: insight into the functional organization of the human central auditory system. (2/10)

The cochlear implant can restore speech perception in patients with sensorineural hearing loss. However, it is ineffective for those without an implantable cochlea or a functional auditory nerve. These patients can be implanted with the auditory brainstem implant (ABI), which stimulates the surface of the cochlear nucleus. Unfortunately, the ABI has achieved limited success in its main patient group [i.e., those with neurofibromatosis type 2 (NF2)] and requires a difficult surgical procedure. These limitations have motivated us to develop a new hearing prosthesis that stimulates the midbrain with a penetrating electrode array. We recently implanted three patients with the auditory midbrain implant (AMI), and it has proven to be safe with minimal movement over time. The AMI provides loudness, pitch, temporal, and directional cues, features that have shown to be important for speech perception and more complex sound processing. Thus far, all three patients obtain enhancements in lip reading capabilities and environmental awareness and some improvements in speech perception comparable with that of NF2 ABI patients. Considering that our midbrain target is more surgically exposable than the cochlear nucleus, this argues for the use of the AMI as an alternative to the ABI. Fortunately, we were able to stimulate different midbrain regions in our patients and investigate the functional organization of the human central auditory system. These findings provide some insight into how we may need to stimulate the midbrain to improve hearing performance with the AMI.  (+info)

Surgical removal of these tumors typically damages the auditory nerve, resulting in deafness. Unlike a cochlear implant, an ABI does not require an intact auditory nerve and can be placed after tumor removal to provide sound sensations to the deafened patient (Prog Brain Res2009;175:333-345).. Research performed over the past several decades has demonstrated that ABIs provide meaningful sound awareness and improve lip-reading scores (Laryngoscope 2005;115[11]:1974-1978 ).. For example, among 26 patients in a study by Barry Nevison, DPhil, and colleagues, all but one patient had auditory sensation at initial ABI activation, and the ABI provided most subjects with some ability to appreciate sound (Ear Hear 2002;23[3]:170-183). However, benefits for individual ABI patients have varied substantially, as noted by Marc S. Schwartz, MD, et al (Stereotact Funct Neurosurg 2003;81[1-4]:110-114).. While US otologists and neurosurgeons have predominately used auditory brainstem implants in the adult NF2 ...
Single or Multi-Channel Cochlear Implants Cochlear implants are recognized as an effective treatment of sensorineural deafness. While use of a unilateral cochlear implant in an individual with severe to profound hearing loss has become a standard clinical practice, bilateral implantation is less common. Evolution of cochlear implant devices has focused on minimizing the internally implanted electrodes, such that one device, the Nucleus® 24 (Cochlear Americas, Englewood, CO), received FDA approval (2000) for use in children 12 months of age and older. A review of the early peer-reviewed literature includes several reports on individuals with bilateral cochlear implants (Long, 2003; Muller, 2002; Schoen, 2005; Tyler, 2002; van Hoesel, 2002; van Hoesel, 2003). These early reports evaluated small numbers of individuals and provided limited outcome information. In these reports, most, but not all, individuals reported very slight to modest improvements in sound localization and speech ...
When ABIs are provided to patients who have lost their auditory nerve from causes other than NF2 (non-tumor or NT patients), the outcomes of the ABI are dramatically different. Colletti and colleagues in Verona, Italy, have demonstrated that about 50% of NT ABI patients have sentence understanding of more than 50% with only the sound from the ABI without speechreading (Colletti & Shannon, 2005). Several of these patients achieved speech understanding equivalent to the best performance of CI patients. These results demonstrate that electrical stimulation of the human brainstem (CN) can provide excellent speech understanding for some patients. It also suggests that the cause of poor speech recognition in NF2 ABI patients may be related to NF2. However, recent results in Europe have demonstrated speech recognition levels similar to those of CI patients in NF2 ABI patients-a level previously not obtained by hundreds of patients with ABIs around the world (Behr et al., 2007). Several NF2 ABI patients ...

Short stem prostheses provide conservative surgery and favorable metaphyseal load transmission. However, clinical long‐term results are lacking. Therefore, in vitro trials can be used to predict bone‐implant performance. In this in vitro study, primary stability and stress shielding of a new cementless short stem implant was evaluated in comparison to a straight stem using nine pairs of human cadaver femurs. Primary stability, including reversible micromotion and irreversible migration, was assessed in a hip simulator. Furthermore, changes in the pattern of cortical strain were evaluated. The short stem was more resistant to reversible micromotion and irreversible migration into retroversion. Axial stability was similar, with mean reversible micromotions of 9 µm for the short stem and 7 µm for the straight stem. Proximal load transmission was more physiological with the short stem, though both implants could not avoid stress shielding in Gruen zones 1 and 7. Primary stability of the short ...

TY - JOUR. T1 - Periprosthetic fractures of the humerus. AU - Schmidt, A. H.. PY - 1999/1/1. Y1 - 1999/1/1. N2 - Periprosthetic fractures of the humerus complicate 2-4% of total shoulder arthroplasties. Intraoperative fractures are more common than those that occur after surgery and are usually the result of faulty surgical technique. Patients with osteoporosis are at increased risk for periprosthetic fracture of the humerus, and these injuries are most common in patients with rheumatoid arthritis. Common mechanisms of intraoperative fracture include excessive external rotation forces because of poor operative exposure, improper starting hole location, and too forceful impaction. Intraoperative fractures should be stabilized with cerclage wires, and long- stem implants should be used if the fracture involves the shaft of the humerus. Postoperative fractures frequently compromise the functional abilities of the patient; operative treatment seems to give the best results. Treatment is based on a ...
In less extensive cholesteatomas, especially when infection is well controlled before surgery, an intact canal wall operation may be the favoured procedure. This operation preserves the wall between the middle ear and mastoid. The principal advantages of the intact canal wall operation are a more normal canal and ear drum, and a greater possibility of hearing restoration. In addition, most patients with the intact canal wall operation can allow water in the ear. The chief disadvantage of the intact canal wall operation is that a regrowth of cholesteatoma may not be evident. Thus, many ear surgeons will delay rebuilding the bones of hearing for a year after an intact canal wall operation for cholesteatoma. The ear drum is opened at the second operation and the bones of hearing are then reconstructed. If a regrowth of cholesteatoma is found, the disease is again removed and reconstruction may be delayed for another 6 months or a year. Repeat CT scans may also be performed in some cases to avoid ...

The mammalian cochlea is a complex macroscopic structure due to its helical shape and the microscopic arrangements of the individual layers of cells. To improve the outcomes of hearing restoration in deaf patients, it is important to understand the anatomic structure and composition of the cochlea ex vivo. Hitherto, only one histological technique based on confocal laser scanning microscopy and optical clearing has been developed for in toto optical imaging of the murine cochlea. However, with a growing size of the specimen, e.g., human cochlea, this technique reaches its limitations. Here, we demonstrate scanning laser optical tomography (SLOT) as a valuable imaging technique to visualize the murine cochlea in toto without any physical slicing. This technique can also be applied in larger specimens up to cm3 such as the human cochlea. Furthermore, immunolabeling allows visualization of inner hair cells (otoferlin) or spiral ganglion cells (neurofilament) within the whole cochlea. After image ...

This paper presents the effects of spontaneous random activity on information transmission in an auditory brain stem neuron model. In computer simulations, the supra-threshold synaptic current stimuli ascending from auditory nerve fibers (ANFs) were modeled by a filtered inhomogeneous Poisson process modulated by sinusoidal functions at a frequency of 220-3520 Hz with regard to the human speech spectrum. The stochastic sodium and stochastic high- and low-threshold potassium channels were incorporated into a single compartment model of the soma in spherical bushy neurons, so as to realize threshold fluctuations or a variation of spike firing times. The results show that the information rates estimated from the entropy of inter-spike intervals of spike trains tend toward a convex function of the spontaneous rates when the intensity of sinusoidal functions decreases. Furthermore, the results show that a convex function of the spontaneous rates tends to disappear as the frequency of the sinusoidal function

A bone-anchored hearing aid (Baha) consists of a titanium implant located at the mastoid, and a sound processor connected with the implant. The sound processor delivers bone conducted stimuli to the cochlea, bypassing the outer and middle ear.. Some patients who are unable to wear or do not benefit from a conventional air-conduction hearing aid, are candidate for a Baha. Typically, these patients suffer from a conductive or a mixed hearing loss. Recently however, Bahas are also being recommended in patients with unilateral deafness. Sound coming from the deaf side is captured and transmitted through bone conduction to the normal inner ear. The overall benefit of a Baha is more difficult to assess in those patients.. Therefore, the goal of the current study is to examine the benefit of a Baha in patients with different audiological profiles (unilateral or bilateral conductive or mixed hearing loss, and unilateral deafness). Special attention will be given to predictive determinants of the ...

N2 - Click-evoked auditory brain stem responses (ABRs) were measured using a Beyer DT48 circumaural earphone and an Etymotic ER-3A insert earphone in a group of normal-hearing subjects. Comparisons were made between time waveforms and amplitude spectra for the two transducers. ABR waveforms, latencies, and thresholds were compared for the two transducers. Click-evoked ABR and behavioral thresholds were comparable for the two earphones. In addition, absolute response-component latencies differed by an amount that was equivalent to the travel time introduced by the insert earphones sound-delivery tube. Inter-peak latency differences were virtually identical. These findings suggest that the insert earphone is a viable transducer for clinical ABR evaluations. Further, a temporal ...
