With the advancement of medical science over the last few decades, one would think that we would be abe to explain the reasons for each individual's hearing loss, unfortunately this is not the case. Conductive Hearing Loss occurs when there is a problem in the outer ear or the middle ear, such as ear wax, fluid behind the eardrum, or middle ear infection. The Hearing Device Center is committed to providing clinical services to those children and adults with specific needs regarding cochlear implantation and amplification. Hearing Animations: In order for the normal process of hearing to take place, all of the intricate components of the outer, middle and inner ear must function normally. Middle Ear: Comprised of the eardrum (tympanic membrane) connected to three tiny bones that move together to send sound vibrations to the inner ear.
View the animation below to learn more about how we hear with normal hearing and with a cochlear implant.
All patients will be seen for a candidacy evaluation by the cochlear implant audiologist and the implant surgeon. Patients return for initial programming of their device approximately three to four weeks following surgery.
In cases where the middle ear function is blocked, damaged or occluded, the Baha system may be a better option as it bypasses the outer and middle ear altogether. We receive sound in two ways, by air conduction via the ear canal, eardrum, and ossicles, and by bone conduction. In most cases, those with a hearing loss will be fitted with traditional air conduction devices. The Baha system, which is based on bone conduction, utilizes a titanium implant, which is placed in the skull bone behind the ear. Direct bone conduction, provided by the Baha implant, may give improved access to sound when compared to traditional bone conduction hearing aids because sound is not weakened or distorted by passing through the skin, muscle and fat covering the skull.
After a period of approximately three months (six months for children) the implant will have osseointegrated with the bone.
No matter where you are, the Baha BP100 automatically selects the optimum combination of sound processing settings. Children born with, or later aquiring middle or outer ear problems, or single sided deafness (SSD)TM, can still benefit from bilateral hearing. Children using Baha can be taught to clean the abutment just as they are taught to clean their teeth. Cautions: If it is used during the fixture healing process, the sound processor must not be placed on top of the abutment or implant as this might jeopardize osseointegration.
One of the benefits of choosing Baha is that you can ask your hearing care professional for a Baha demonstration, so you can hear the difference yourself.
Potential recipients can easily test the Baha so that they can experience the benefits before they have surgery. You can wear it for all normal activities, but you should take off the sound processor before going to sleep, taking showers, swimming or other water. Many thousands of people have been treated so far – some of whom have been wearing Baha sound processors since they were introduced in 1977.
Conductive hearing loss with no other surgical option, Sensorineural hearing loss with intolerance of hearing devices, unilateral deafness. An auditory brainstem implant (ABI) provides a sensation of hearing to deaf people by directly stimulating the brainstem. The device is used most commonly in people with neurofibromatosis type II (NF-2), a disease causes tumors to form on the balance and hearing nerves, which usually results in deafness. In people with NF-2, the ABI usually is placed at the same time the nerve tumors are removed, so it's completed within one surgery.
The device doesn't give the full range of hearing, but it provides increased environmental noise awareness. Diseases that damage the inner ear and the auditory nerve connecting the inner ear to the brain (such as Neurofibromatosis Type II in which bilateral acoustic neuromas are present) require a novel solution to provide hearing.
The device (very similar to a cochlear implant) is placed under the skin behind and above the ear. The VIBRANT SOUNDBRIDGE® is the first FDA approved implantable middle ear hearing device to treat sensorineural hearing loss (the most common form of hearing loss). Information provided on this website is for informational purposes only and is not a substitute for professional medical advice.
The questions below may be helpful in determining whether you are a candidate for the MED-EL Vibrant Soundbridge®.
Keep in mind that only an Audiologist or Otologist can determine whether your hearing loss is appropriate for this device.
The Vibrant Soundbridge significantly improved patients' perceived benefit in many listening situations, such as: familiar talkers, ease of communication, reverberation, reduced cues, background noise, aversiveness of sound, and distortion of sound. The Vibrant Soundbridge significantly reduced acoustic feedback when compared to the patients' own hearing aids. Patients reported that the Vibrant Soundbridge provided better overall fit and comfort compared to their own hearing aids, and reduced maintenance issues due to cerumen and moisture accumulation.
The Vibrant Soundbridge provided equal or increased functional gain when compared to the patients' own hearing aid.
The Vibrant Soundbridge consists of two components, one internally implanted and the other externally worn that work together enhancing the normal middle ear hearing function.
The Audio Processor picks up sound from the environment and transmits that sound across the skin to the implanted receiver. The FMT is a tiny transducer that directly vibrates the ossicles by mimicking the natural motion of the ossicular chain, sending an enhanced signal to the fluid-filled inner ear (cochlea). That ossicular motion creates movement in the fluid of the cochlea, stimulating the hair cells. Candidacy evaluations include a series of hearing tests to determine if your hearing loss is appropriate, followed by a medical exam to determine your surgical candidacy. If you have private insurance, there is a good chance that your insurance may cover the Soundbridge implant procedure. Occlusion is the sensation of hearing distorted, muffled sounds experienced when an object blocks the ear canal. Can the Vibrant Soundbridge be customized to different levels of hearing loss, and can it be upgraded when new technologies are developed? The Vibrant Soundbridge is fully programmable using software that enables audiologists to customize the device depending on patients’ individual hearing needs. The procedure to implant the Vibrant Soundbridge is done on an outpatient basis and it takes approximately one and a half to two hours. Extensive clinical studies conducted in the Unites States and Europe have confirmed that the Vibrant Soundbridge is a safe and effective treatment option for adults with moderate to severe sensorineural hearing loss who are seeking an alternative to acoustic hearing aids. Hearing aids, which are worn in the ear canal, amplify sound acoustically in order to increase the movement of the eardrum and indirectly vibrate the middle ear bones.

This presentation will focus on cochlear implant candidacy criteria and how it has changed over the years to current standards. In this webinar, several unusual causes of conductive hearing loss will be examined including enlarged vestibular aqueduct, superior semicircular canal dehiscence, malleus fixation and cerebrospinal fluid leak. This presentation will focus on bilateral cochlear implants and the differences between simultaneous and sequential. Cases that are virus positive also are positive for TNF-alpha, suggesting a possible link to autoimmune inner ear disease.
In otosclerosis, the most commonly affected portion of the bone around the inner ear (otic capsule) is the anterior oval window (about 96%). Disorders that can be mistaken for otosclerosis (a disease) include disorders of the inner ear bones (ossicles), and fluid within the middle ear. Examples of disorders of the inner ear bones other than otosclersosis include ossicular chain disruption and ossicular fixation. In congenital ossicular fixation, the normal articulation of the small ossicular bones does not occur. Bedside: The otologic clinician should confirm audiological testing suggesting a conductive hearing loss with bedside examination. VEMP testing can also be used to diagnose superior canal dehiscence and distinguish otosclerosis from SCD. The symptom of paracusis Willisii, where the patient perceives speech better in a noisy background, is said to be frequently present in otosclerosis as well as other causes of conductive hearing loss. Otosclerosis does not have to be treated, as there are no medications that have been shown to work, and it will progress or not independent of any treatment. Hearing aids are effective for conductive hearing loss and certainly are less risky than having ear surgery. Lictor (2013) reviewed all medical treatments and concluded that there is no medical treatment proven to work. At the present writing, fluoride therapy is no longer a recommended primary treatment for otosclerosis (NIH consensus), because of its effect on other bones including the possibility of increasing the risk of hip fractures. Lippy and Berenholtz suggest adding Caltrate and 30 mg of risedronate (a biphophonate -- Actonel) in persons who do not respond to Florical and Vitamin D. The author's advice on stapedectomy (the author is not an otologic surgeon), is that the BAHA implanted hearing aid, as well as similar devices, seem better suited to treatment of otosclerosis and similar causes of conductive hearing loss than stapes surgery.


Surgery should also not be performed in patients whose hearing loss is 70 dB or less unless their speech discrimination score is 80% or better. Riggs BL, Hodgson SF, O'Fallon WM, Chao EY, Wahner HW, Muhs JM, Cedel SL, Melton LJ 3rd.1990.
Effect of fluoride treatment on the fracture rate in postmenopausal women with osteoporosis.
Almost half are under the age of 65 and 54% of the population over the age of 65 suffer from hearing loss.
Many times this type of hearing loss may be corrected by medical or surgical treatments.Symptoms of Hearing Loss. Individuals are seen for extensive comprehensive evaluations to determine both audiological and surgical candidacy and receive extensive information regarding device options. The hair cells are responsible for sending impulses to the auditory nerve fibers, then on to the brain for interpretation into sounds. The audiologist that is working with you in the clinic will fit the external equipment to make sure that all components are appropriate. Instead, sound is sent around the damaged or problematic area, naturally stimulating the cochlea through bone conduction.
The sound processor may now be attached to the abutment, enabling the recipient to hear with the Baha®system fully in place for the first time. The BP100 now has both automatic noise reduction and directional microphones to help improve your ability to understand speech in background noise, such as a restaurant. Hearing is a vital part of a child’s learning process and it's of great importance to start stimulation for speech and language development as early as possible. The FDA has only cleared implant placement in children age 5 and up, who have stronger and thicker skull bones. The Baha sound processor can be easily attached to the plastic connector and the band can be worn by kids of any age, including a newborn baby. Additionally, the Baha system does not preclude any benefits from future hearing technological advances because it doesn’t compromise middle or inner ear or compromise hearing nerve sensitivity. It can be connected to a test band, test rod or the Softband, which allows you to try the sound processor in different environments such as at home, at work etc. But you should never hold the phone against the sound processor itself, because this could cause feedback problems. Over the last 10 years, Baha has become a treatment of choice for thousands of hearing impaired people worldwide, and the numbers of Baha users are increasing rapidly.
After a 2 month healing phase, a sound processor is attached to the post allowing transmission of hearing directly to the inner ear, bypassing the eardrum and middle ear structures.
The ABI bypasses the cochlear nerves, so it may be an option for individuals with nonfunctioning or absent cochlear nerves.
The device comprises a tiny microphone positioned by the ear, a decoding chip and an array of electrodes implanted on the brainstem.
After surgery, the patient returns for multiple sessions with an audiologist to test and adjust the sound processor, and to learn and interpret new sounds. Most patients are able to hear noises like a telephone ringing or horn honking, but the degree of hearing usefulness can vary greatly.
In this procedure and with this device, the hearing pathway is stimulated electrically at its connection to the brain. An electrode is placed through the inner ear and connected to the auditory nucleus on the portion of the brainstem where the hearing nerve connects from the inner ear.
A proven, safe and effective treatment that leaves the ear canal completely open, the Soundbridge features a 94% improvement in patient satisfaction1, with thousands of patients worldwide. Only your healthcare provider can diagnose your healthcare problems and prescribe treatment.

The hair cells provide stimuli to the auditory nerve, which are then interpreted by the brain as sound. The implant surgery itself is a 2-hour outpatient procedure, performed under general anesthesia. Phase III Clinical Trial results with the Vibrant Soundbridge Implantable Middle Ear Hearing Device.Prospective Controlled Multicenter Study. Since February 2002 many of the patients who have submitted the Soundbridge procedure for payment have been successful. They are implanted directly in the inner ear, or cochlea, where they electronically stimulate the nerves through a series of electrodes. It is a common complaint among hearing aid users, who often find that the presence of the hearing aid, or hearing aid ear mold, in their ear canal distorts not only outside sounds but also the sound of their own voice. The Vibrant Soundbridge is designed to accommodate technology advances via the Audio Processor.
A typical patient who uses their Vibrant Soundbridge 12-16 hours a day may need to change the battery about once a week. Implant patients are exposed to the normal risks of middle ear surgery and general anesthesia. The Vibrant Soundbridge is a direct drive device which mechanically vibrates the bones in the middle ear without surgically altering the structures of the middle ear.
In contrast, the Vibrant Soundbridge is an implantable prosthetic that provides an enhanced signal to the inner ear by directly vibrating the middle ear bones, while leaving the ear canal open and the eardrum undisturbed. Jill Messina has experience with audiological and vestibular diagnostic assessment, electrophysiological testing, hearing aids, aural rehabilitation, and supervision of audiology Doctoral students. The presentation will include brief videos of the mechanics of ossicular reconstruction and surgical reconstruction of the ossicles including stapedectomy. The differentiating features of these unusual causes of conductive hearing loss will be discussed relative to more common causes of conductive hearing loss. We will also discuss the process of obtaining bilateral cochlear implants, decision making process, audiologic criteria, benefit of bilateral hearing, surgery, programming, and case studies. Although hearing loss is usually diagnosed in early adult life, the prevalence increases almost 7-fold with age (Niedermeyer et al, 2001).
This may be mediated by increased activity of the renin-angiotension system (Imauchi et al, 2008).
There are some differences in opinion about this - -as about 100% of monozygotic twins match up with respect to otosclerosis (Fowler, 1966). The author's clinical experience suggests that this estimate may be an order of magnitude too high, as practically, otosclerosis is a rare diagnosis and getting rarer.
It can also involve the round window niche (30%), the internal auditory canal, and occasionally ossicles other than the stapes (Schuknecht and Kirchner 1974; Schucknecht, 1993). The reason for this is that mistakes can be made, and when there is a significant hearing loss, inexperienced audiologists may omit or use masking incorrectly.
We have not found this to be useful and in fact find tymps to be almost universally normal (see tymps in figure towards top of this page).
As mentioned above, VEMP's should be absent in conductive hearing loss, but present in sensorineural hearing loss. The main reason for this is to exclude alternatives (such as tumors or Menieres-- otosclerosis does not protect you from other ear diseases), and also to keep in touch with the audiologist in regards to when a hearing aid might be indicated. Hearing aid technology has undergone tremendous advances since the invention of surgical treatment for otosclerosis. Monical is a preparation that is absorbed in the intestine rather than in the stomach and may cause less side effects. Note that the small end of the prosthesis is no longer adjacent to bone, and also that the entire prosthesis has rotated about 45 degrees clockwise. If the prosthesis migrates inward, then ear drum movement may directly stimulate the saccule utricle. This operation, which involves drilling out the bone of the mastoid, is rarely if ever offered.
This may be due to increasing prevalence of measles immunization, catching up on the backlog of cases that existed before surgery was available, or just changes in how conductive hearing loss is treated.
Devices like the BAHA have less risk of dizziness or failure, and more control over the outcome. Always test each patient at least twice before doing the surgery (because mistakes can happen). We ourselves would modify this to say that acoustic reflexes should be either absent or inverted. Hearing loss is the third most common medical condition in our adult population, following only high blood pressure and arthritis.
With this type of hearing loss the hair cells in the inner ear (Cochlea) have become damaged or less effective.
If you recognize any of the following symptoms of hearing loss, please contact one of our offices or your personal physician to have your hearing professionally evaluated. Our facility offers a selection for implantation of all FDA approved manufacturer’s devices including Cochlear Corporation, Advanced Bionics and MedEl. New implant users (children and adults) often find that one-on-one therapy initiated shortly after they obtain their device is very beneficial! However, younger children can be fitted with a Baha sound processor with an external attachment.


The Softband is often used as a temporary solution until the child is old enough for surgery. In the US, children aged five years and older are cleared by the FDA for implantation, but younger children can use a Baha with a Softband. A telecoil unit can be used with any Baha to help improve the sound quality of an ordinary phone that is fitted with a loop or a coil. The ABI connects directly to the brainstem, bypassing the damaged cochlea and cochlear nerves.
This process can take significant time, because the sound cues from an ABI are different from normal hearing. This procedure is usually done in conjunction with a translabyrinthine approach for acoustic tumor removal and the closure is accomplished in the same fashion. Please select topics from the menu on your left to read more about hearing loss and treatment options. It has been approved by the FDA as a safe and effective treatment option for adults with moderate to severe sensorineural hearing loss who have been unsuccessful with or are medically unable to wear hearing aids. It is 100% digital and is programmed by an Audiologist to fit the user's specific hearing loss. The internal receiver is placed under the skin behind the ear, and the FMT is attached to one of the bones of the middle ear. In contrast, the Vibrant Soundbridge is for hearing-impaired people with moderate to severe hearing loss.
The tiny FMT ™, part of the implant and the component that is attached to the bone (incus) in the middle ear, is approximately the size of a grain of rice. As a result, patients will be able to take advantage of new signal processing circuits and enhanced programming options as they become available without further surgery. He is in private practice at the Ear Institute of Illinois (formerly called the Ear Institute of Chicago) in Hinsdale, Illinois.
Renin blockers (tekturna -- Aliskiren) are available, as well as many angiotension convertase inhibitors (ACE), but to our knowledge, no one has attempted their use to block worsening of otosclerosis in pregnancy. Nuclear inclusions similar to paramyxoviral nucleocapsids have been observed in otosclerosis osteoclasts (McKenna et al, 1986; Chole and McKenna, 2001). Otosclerosis is thought to begin with otospongiosis, which is a localized softening of the normally very hard bone of the otic capsule (Shambough 1971). The malleus can be fixed at the anteior nuchal ligament, or the head can be adherent to the medial-most portion of the ear canal. Lippy and Berenholz) suggest that this condition can be diagnosed with a flat sensorineural hearing loss, good speech discrimination, absent acoustic reflexes, and a family history.
It is best to confirm the conductive hearing loss both with the tuning fork test (512 hz) -- both Weber and Rinne, and with the VEMP test. This is the same patient as above (right) where the Right ear was operated, and the left ear unoperated, but both clearly had stapedial otosclerosis. This being said, it is still difficult to see the logic and we ourselves have never seen a patient who has volunteered this observation. It would seem to us, that one would need to consider both the risk of hearing progression, and balance it against the risk of adverse effects on other bones, when prescribing. Cruise et al (2010) indicated that there is only low-quality evidence for sodium fluoride therapy being effective in otosclerosis.
If it migrates outward, a fistula can arise at the oval window, from which the prosthesis was dislodged. Because it involves creating an otic capsule fistula, similar to that seen in superior canal dehiscence, it has many untoward effects.
The surgeon should be prepared, if necessary, to repair the ear drum prior to the operation, treat all infections prior to the operation, and remove exostoses at the time of the ear surgery. On average, once a person determines that they have a hearing loss, they wait over seven years before seeking assistance.The impact of a hearing loss can be far reaching and involve many aspects of one's life.
The therapist can assist in establishing realistic goals and expectations, help the individual to maximize their listening potential, assist with IEP goal selection, and provide home program exercises. In contrast, traditional bone conduction hearing aids connect indirectly to the bone through unbroken skin (transcutaneous) and work by exerting pressure against the skull. Surgery is minor, and Baha recipients report a wide range of advantages over other hearing devices.
Until recently, only uncomfortable metal steel spring headbands were available as an option for children to use Baha while awaiting surgery.
The sound processor is held against the skin behind the ear, or at another bony location of the skull, through the pressure from the band. The microphone picks up sounds from the environment and digitally transmits them to a decoding chip placed under the skin.
Prior to receiving the device, it is recommended that an individual have experience with appropriately fit hearing aids.
About 8 weeks after surgery, after the external audio processor is digitally programmed by an audiologist to best fit your hearing loss, the Soundbridge is activated.
It provides an enhanced signal to the inner ear by directly vibrating the middle ear bones. She is working in conjunction with the physicians of the Ear Institute of Chicago, LLC on a research study examining the Vibrant Soundbridge as a method for treating conductive and mixed hearing losses.
This would be consistent with the observation that it is of variable penetrance, as one would expect a single gene to be more consistent in behavior.
Measles virus RNA has been found in the stapes of otosclerotic persons (Potocka-Baklazek et al, 2014).
On the other hand, about 40% of stapes from otosclerosis patients are negative for measles (Karosi et al, 2007), and it is also unclear why measles should affect the temporal bone, but not affect other bones in the body. To our knowledge, nobody has yet attempted to apply this finding with anti-TNF drugs such as entanercept.
There appear to be three stages of otosclerosis -resorptive osteoclastic stages with signs of inflammation, followed by an osteoblastic stage involving immature bone, followed by mature bone formation. OPH is found in high concentration in the perilymph (Zehnder et al, 2005), and thus lack of OPG might be thought of as a possible explanation for the the otospongiosis part of otosclerosis. To us, this clinical picture would seem rather difficult to distinguish from any other type of sensorineural hearing loss.
VEMP's should be absent in a conductive hearing loss but present in sensorineural hearing loss. Another possible explanation is that persons with sensorineural hearing loss have great problems hearing in noise, perhaps because of loss of outer hair cells, but this is simply not the case in conductive hearing loss. There is not much one can do about a failed stapes procedure other than take more CT scans adding on more radiation, and then do more surgery. Hearing impaired individuals may have difficulty localizing sounds, understanding speech in busy environments, and participating in everyday normal conversations. Audiologic unaided and aided testing will be performed to assess hearing ability and benefit as well as an assessment of word recognition ability with amplification devices.
Even families of children who are already receiving therapy services at school find that adjunct services in the private sector are quite beneficial.
These proved difficult to wear for some children due to discomfort and difficulties keeping the headband in place.
They need to practice good hygiene in the Baha implant area and to be supervised by responsible adults who also ensure that the Baha care and maintenance instructions are followed.
The chip stimulates the brainstem electrodes, allowing the patient to hear a variety of sounds. View PDFSigns and SymptomsUnilateral sensorineural hearing loss is most common presenting symptom of a patient with an acoustic neuroma. As the treatments for cochlear otosclerosis vary from doing nothing to an unproven medical treatment (sodium fluoride), we would favor simply diagnosing such patients as having sensorineural hearing loss. This can lead to social isolation, confusion, frustration, tension, anger, stress and depression. Once programming has been completed and a useable program has been downloaded to the processor, the external equipment function is reviewed with the recipient. Especially because these services are provided here, at the Cochlear Implant Center, allowing for excellent communication and continuity of care between all of the implant team members. The band can be turned so that the connector is not always in the same position, which will help to avoid skin discomfort. This is called Schwartz sign -- it is not a reliable sign and should not be relied upon (Lippy and Berenholz, 2008). Recent studies also indicate that untreated hearing loss negatively affects one's overall health, quality of life and happiness.Causes of Adult Hearing Loss.
