Our ears, and what?s inside them, are a complex and delicate structure, and one that?s very easy to damage.
Sensorineural Hearing Loss, or SHL for short, is a condition that affects the sense of hearing. There are a number of causes for acquired SHL, with both external (outside world) and internal (the person?s own body) affecting an ear?s health.
Whereas conductive hearing loss can be treated (as in the case of acquired CHL if the trauma involves barotrauma, for instance) the treatment of SHL depends on a number of different factors (source).
The Hearing Loss Pill is the newest treatment especially designed for Sensorineural Hearing Loss. While there are some causes of SHL that can?t be avoided, such as ageing or genetics, it?s still important to treat the ears as the fragile instruments they are. Think of it this way: we all know how damaging it is to walk around in bright summer sun with little skin protection. If you are interested in learning more detailed information on the available ways to improve hearing loss, including stem cells, cochlear implants, hearing aids and of course The Hearing Loss Pill, please see our hearing loss treatment page. Whatever its cause, conductive hearing loss decreases the energy of the sound waves that causes the fluid of the inner ear to move, this translates as a decrease in sound perception.
Treatment of this condition begins by re-establishing the ventilation of the middle ear by inserting small vents, called grommets, into the eardrum. Repair of the ossicular chain: ossicle prosthesisA perforated eardrum or the blockage or damage of the ossicles can be remedied by surgical intervention or a hearing aid. Some causes of conductive hearing loss are wax in the ear canal, fluid in the middle ear, or a hole in the eardrum. Children with sensorineural hearing loss also can have middle ear problems (such as fluid in the middle ear).
Though there may be deficits in every sensory modality, for educational purposes, CHARGE is considered to be a deaf-blind syndrome. Within individuals, each of the 20+ possible anomalies may be absent or present (varying in degree of expression from mild to severe).
Individuals with CHARGE syndrome are typically delayed in development-motorically, intellectually, and physically. External ears typically are malformed and have patterns of malformation that are so distinctive that preemptive diagnoses of CHARGE can be made on the basis of unusually shaped, asymmetrical pinnae.
Middle ears typically have ossicular malformations that result in conductive losses that are greatest in the low frequencies but can be present at all frequencies.
This audiogram was selected to illustrate asymmetry of hearing loss between the ears, which is common in CHARGE syndrome. This is a rare case of familial CHARGE syndrome that includes the woman whose audiogram is shown, her mother, her brother (one of her four siblings), and three of her nine children (Thelin, Mitchell, Hefner, & Davenport, 1986).
This audiogram was selected because it illustrates (a) asymmetrical hearing loss and (b) bilateral mixed loss with significant cochlear loss that is difficult to treat.
A unique aspect of this individual's auditory problems is that even though the cochlear sensitivity in the left ear is in the moderate to moderately severe hearing loss range, because of the large conductive loss, the left ear is unaidable.
This audiogram was selected to illustrate the magnitude of conductive loss that can be present in CHARGE syndrome.
The solid lines (labeled with an S) indicate the pure-tone thresholds obtained with supra-aural earphones. It is our opinion that the thresholds with the supra-aural earphones significantly underestimate the true degree of hearing loss and that a better estimate of the air-conduction thresholds is obtained with insert earphones (dashed lines labeled with an I). Individuals with CHARGE often have physical and sensory disorders, limited communication ability, and behaviors that provide challenges in the assessment of hearing and the treatment of hearing loss.
Communication A significant percentage of individuals with CHARGE have no symbolic communication. Behavior Individuals with CHARGE may exhibit tactile defensiveness, attention deficit disorder, autistic-like behaviors, self-stimulatory behaviors, and in extreme cases, self-mutilation. Mucus and Saliva Children with CHARGE often have major breathing, swallowing, and feeding problems.
Communication Bubble For many individuals with CHARGE, their combined auditory and visual deficits are so significant that they have only a small area in front of them in which they can communicate optimally. Parents of Children with CHARGE Parents of children with CHARGE have likely seen dozens of health care providers before seeing an audiologist. The ASHA Action Center welcomes questions and requests for information from members and non-members.
Hearing loss is a symptom of a variety of conditions affecting the hearing organ or its nerve connection to the brain.
Conductive hearing loss is caused when something interferes with the transmission of sound from the ear canal to the cochlea. Conductive hearing loss can be due to problems in the ear canal, ear drum (tympanic membrane) or the middle ear bones (ossicles). Rarely children may be born with poorly formed middle ear bones, or these structures can be damaged through ear infection.
Conductive hearing loss in adults is less common, but may be due to problems with the bones of hearing or occasionally glue ear.
Sensorineural hearing loss is due to loss of sound sensing cells in the cochlea (These are called hair cells) or damage to the nerves that take hearing signals to the brain. Children can also suffer from sensorineural hearing loss, and for some children this is an inherited disorder that may even be present at birth. Finally it is worth remembering that hearing loss can be due to a mixture of conductive and sensorineural causes. Most adults first start to notice difficulty in following conversation when there is background noise or when more than one person is talking. In children, parents find that they might be inattentive, or ignore instructions or appear naughty. Action On Hearing Loss, formerly The Royal National Institute for the Deaf (RNID), offers an Online Hearing Test. In most circumstances you should see your doctor, who will be able to examine you for wax impaction and look for signs of ear disease.
In cases where the hearing loss is due to a problem with the ossicles (eg otosclerosis) surgical hearing restoration is usually possible.
With modern surgery and high technology devices ENT surgeons are able to offer even the most severely deaf patients useful hearing. People with SHL can be born with it or else acquire it over the course of a lifetime or as a result of a particular incident, such as head trauma or a sudden loud noise. It occurs when damage or disorder renders the inner ear (such as the cochlea) ineffective in receiving and transmitting soundwaves as signals to the brain. In fact, many of us will acquire this in one form or another over the course of our lifetime. Conductive hearing loss is when sound is being blocked from reaching the inner ear in order to be registered as sound by the brain. The basics may simply be for the doctor to cover one of the patient?s ears at a time and speaking at different volumes to determine if there?s anything abnormal. As the particular situation varies from person to person, the approach to treatment varies as well.
This new treatment is designed to improve hearing by targeting the nerves in the inner ear that are still working.
Limit time spent in environments with a high level of noise, such as workshops, in traffic or at airports. We?ve been told it?s a one-way ticket to skin damage and potentially risking skin cancer and melanomas.
The nerves that make up the hearing process are the vestibulocochlear nerve, the processing centers of the brain, or the actual inner ear itself.

Right now there is an FDA approved study being conducted to evaluate whether or not hearing problems can be cured using stem cell treatments. The Hearing Loss Pill is not a cure, but is instead an ongoing treatment to gradually help improve the nerves of the inner ear, and help the brain better process it. The truth is that most people never do anything with the products they buy, so most of the time, they dona€™t get ANY results. Although the inner ear still works properly, sound is perceived as less intense because of the attenuation of the sound vibrations. This extremely common surgical intervention is accompanied by further diagnostic tests into the underlying cause of the condition, and further treatment.This cause is often abnormal function of the Eustachian tube, which can occur with gastric reflux, allergy, smoking (even passive), or by the presence of considerable vegetal growth in the tube.
Each method has its advantages, inconveniences and counter-indications.In a first case, reconstructing the ossicles aims to return the physical integrity to the system that transmits the sound, therefore improving the mechanical conduction of sound vibrations.
The anomalous pinnae rarely cause hearing loss, but they are often so soft and floppy that they may not support a behind-the-ear hearing aid. Many different forms of structural anomalies have been reported, including Mondini's dysplasia, which includes dwarf cochleas and incomplete formation of the semicircular canals. The most common features are asymmetrical mixed losses that are severe-to-profound in degree. In this case, there is asymmetry in both the conductive and cochlear components and in the overall degree of hearing loss in the two ears.
Among these individuals, auditory anomalies were found for every individual, but hearing levels ranged from normal to profound hearing loss. In the right ear, there is a mild conductive loss through 1500 Hz falling to a profound mixed loss in the higher frequencies.
She wears a behind-the-ear hearing aid in the right ear, but when there is effusion, her aided benefit is reduced. The tympanograms were shallow but peaked at room pressure-indicating that the conductive loss was not due to eustachian tube dysfunction or middle-ear effusion but rather to ossicular anomalies. It is our interpretation that these thresholds were "bone-conduction" thresholds because, at these signal levels, the earphone cushion on the pinna begins to act as a bone vibrator rather than as an acoustic sound source. The insert earphones may be generating bone-conducted stimulation as well, but we suspect because of the coupling in the external auditory canal and the reduced amount of sound power required, the stimulation is likely to be acoustic.
These are very large conductive components that are difficult to overcome with conventional hearing aids without encountering feedback.
For individuals with limited communication abilities, the presence of an adult who understands the individual's communication system is very helpful. These challenging behaviors are those by which individuals with severe sensory deprivation deal with the world that they encounter. This is evidenced as a keyhole slot at the bottom of the eye that creates a triangular iris as well as a void on the retina and in the optic nerve. This area has been called the "communication bubble." The size of the bubble varies depending on the individual's hearing and vision, on the presence of background noise, and on lighting (sensitivity to bright light is common).
Because the pinnae are often very soft and misshapen, they will not support conventional behind-the-ear hearing aids. Once the survival of the child is assured, parents shift their focus to development, communication, and learning. Thelin is an audiologist who teaches graduate students and conducts auditory and vestibular research at the University of Tennessee.
It may be caused by problems affecting the transmission of sound through the eardrum and bones of hearing (called ossicles) to the cochlea (the organ of hearing), or it may be due to problems in the cochlea and the auditory nerve that connects the cochlea to the brain (Figure 1).
Sensorineural hearing loss is caused when there is a problem with the cochlea, or the nerve connection from the cochlea to the brain. Heavy wax accumulation in the ear canal can also cause a mild degree of conductive hearing impairment.
Often their friends will complain that they don’t listen or that they turn the television volume up too loud.
Listening to the television at high volumes is common and some times the child’s teachers will complain.
A variety of tests are available, and special test techniques can be used to assess children, even when they are newborns. Treatment depends on the severity of the hearing loss and whether it is conductive or sensorineural. This may involve using metal or plastic implants or reusing your existing ossicles to restore the hearing mechanism. There is a hearing restoration solution available for almost everyone who is hearing impaired. Hearing loss is on the rise, especially in the elderly population, and our modern life is the cause of it.
Sudden Sensorineural Hearing Loss is something else entirely, and not to be confused with SHL ? SHL used to be known as nerve ?deafness?, which is a simple way of looking at a complex situation.
On the other hand, SHL is when sound can reach the ear but the sound isn?t being registered. From there, the tuning fork test may be administered, or an audiometer test for further examination. As such, the ability of the inner ear to recognise and convert sounds to clear signals may be compromised. The product works by helping the existing nerves transfer more "sound information" into the brain for processing and understanding. Obviously, if you?re employed at one of these places, it?s necessary to wear the appropriate type of ear protection to reduce exposure to potentially damaging sound. We already know that it is supposedly already being successfully used in more exotic countries (without much health regulation), but the safety and effectiveness is questionable, not to mention the $30,000+ price tag on the treatment that health insurance will not pay for.
Audiologic evaluation of individuals with CHARGE syndrome can be challenging as a result of characteristics that are unique to this population. Pagon and her coworkers in 1981 (Pagon, Graham, Zozana, & Yong, 1981) to describe six features of a complex genetic disorder. As a result of this complexity, each individual may have a unique set of physical disorders, a unique combination of sensory deficits, and a unique pattern of behavior. However, the documentation of hearing loss that enables either the fitting of appropriate amplification (i.e. The most common report from parents is that their child has reached some developmental milestone well beyond the expected age of acquisition and after the parents had lost hope that the milestone would ever be reached. Eustachian tube dysfunction is almost universal, with most children requiring several sets of tympanostomy tubes.
Recent evidence suggests that the anatomical assessment of the auditory nerve is best accomplished with magnetic resonance images that are supplemented with information obtained by computerized tomography. Conductive components, which are due to a combination of ossicular anomalies and middle ear effusion, are often asymmetrical and fluctuating in nature; cochlear hearing loss, often due to cochlear malformations, is typically greater in the high frequencies. Tympanometry was normal in both ears, indicating that the middle ear losses are due to ossicular anomalies. Unmasked bone-conduction thresholds were measured only on the right ear but are shown for the left ear with a dotted line. The average air-bone gap for the five test frequencies was 61 dB in the right ear and 72 dB in the left ear.
We believe that thresholds obtained with the insert earphones more accurately reflect the individual's hearing loss. This individual's bone-conduction thresholds make him a candidate for bone-conduction amplification or an auditory osseointegrated device.
Frequent breaks may be needed in managing the child and keeping him or her comfortable during assessment.

First, in some cases, the individuals with CHARGE are medically fragile and have breathing and swallowing difficulties that need to be taken into consideration. This can create holes in the visual field that prevent detection of visual images-especially from above the individual. When the individual with CHARGE is unable to walk or move independently to situate himself or herself for optimal communication, the clinician will need to make these accommodations and place the interaction within the communication bubble. Due to permanent and long-standing conductive hearing losses, individuals with CHARGE may be candidates for bone-conduction hearing aids or auditory osseointegrated devices such as the "Baha." Cochlear implantation is sometimes an option, but there are often concerns about the reduced diameter of the auditory nerve and stimulation of the facial nerve by the cochlear implant. Many have accessed the 250+ page manual titled CHARGE Syndrome: A Manual for Parents from the CHARGE Syndrome Foundation Web site.
Our data indicate that there is a significant relationship between development of symbolic communication (spoken or signed language) and early intervention (before 3 years of age) by audiologists and speech-language pathologists. He has worked with parents of children with CHARGE syndrome and individuals with CHARGE syndrome for 25 years. Sensorineural loss can also be due to excessive noise exposure in both work situations (industrial noise damage) or through excessively loud music exposure (recreational noise damage). In conductive hearing loss there may be an infection of other disease process that needs to be treated. The technology in hearing aids is always improving to make them more discrete and offer better sound quality. Hearing aids are inserted into the ear, where they amplify native soundwaves to make them clearer for the ear to recognise. A cochlear implant converts sound to electrical impulses, mimicking the natural hearing process and stimulating the hearing nerve. You know how bad it is to sunbathe without sunscreen, why would you do the same with your ears? The testimonials you see on this web site are some of our better results and are not typical.
Nevertheless, depending upon its cause (noise trauma, Meniere’s disease, auto-immune problems…), specific treatments can be used with variable outcomes. Since 1981, the diagnostic criteria have been revised, and they will continue to be revised. However, the combination of these two sensory deficits almost always results in overall challenges that are much greater than would be expected from the sum of the two. The challenge to the clinician is to determine how best to interface with that individual, recognizing the individual's specific abilities, to obtain diagnostic information and to provide needed treatment. Parents are keenly sensitive to this issue and discount the advice of clinicians who underestimate their child's potential. When the eustachian tube dysfunction is caused by craniofacial anomalies, middle ear fluid and otitis media may persist into adulthood. As a result, individuals with CHARGE may have difficulty walking and performing acts that require balance-related skills, but they rarely have any complaints related to dizziness. Radiographic studies have shown instances of dysgenesis or agenesis of the corpus callosum.
With the large conductive loss in the right ear, if she is eating or chewing gum, the internally generated noise is so great that she cannot understand a person who is talking to her.
For example, the audiologic assessment of a 27-year-old male who was profoundly intellectually challenged and who had very poor vision was possible because this individual would respond to speech stimuli with grunts, head banging, and rapid eye movements.
The challenge to the audiologist is to work through these behaviors to obtain an assessment of hearing and to develop a method of treatment.
Second, some individuals with CHARGE have shown resistance to sedation and do not respond to standard doses of sedatives. If visual reinforcement audiometry is used, the individual may turn his or her head at an unusual angle to place the image on a functioning part of the retina. As a result, audiologists and speech-language pathologists have a great opportunity to improve the quality of life for individuals with this complex and multifaceted disorder. CHARGE syndrome: Multiple congenital anomalies including disorders of all senses and speech, language, feeding, swallowing, and behavior. Vestibular anomalies in CHARGE syndrome: Investigations on and consequences for postural development. Other causes of sensori neural hearing loss include some prescribed medication, and some infections. They stuck to the dose as directed and maintained a healthy lifestyle and balanced diet alongside it.
At present, the criteria include more than 20 physical anomalies, deficits in all sensory modalities, and a behavioral phenotype that is unique.
With multiple sensory deficits, the effects are often subtle and may manifest themselves as unique challenges in communication, learning, and behavior. As a result of very significant sensory deprivation in all modalities, a substantial percentage of individuals with CHARGE do not develop symbolic communication. In the most extreme cases, individuals with CHARGE who have virtually no channels of meaningful sensory input may resort to destructive behaviors and self-mutilation as their only means of communication. It is critical for the clinician to recognize this and to proceed and plan as if goals that may seem unattainable may eventually be attained. In cases with relatively normal hearing, evidence of retrocochlear involvement has been documented using auditory evoked response testing.
Hearing results were specified using the audiometric standard in effect when the audiograms were obtained. He responded consistently to speech in each ear at 60 dB HL and to bone-conducted speech at 40 dB HL, indicating the presence of a bilateral mixed hearing loss.
In many cases, successful treatment of hearing loss opens up the best channel of communication for the individual.
The professionals who are most appreciated are those who acknowledge that they have not encountered CHARGE before but are willing to acquire the information. Other conditions may affect the ossicles, for instance the stapes bone can become attached to the surrounding bone which stops it transmitting sound. Some may use gestures to communicate, while others may rely on more primitive forms of expression.
In some cases, these behaviors have ceased after audiologic intervention that ended the individual's isolation. The conductive component of her hearing loss is probably due to a combination of ossicular anomalies and effusion. To reach this goal, it is often necessary to conduct the assessment in small steps with specific, limited objectives over a series of patient visits. Also, audiologists and speech-language pathologists should understand that parents of children with CHARGE are eternally hopeful about their child's prospects for the future and appreciate the professional who will encourage them even when the challenges are great. Coloboma, congenital heart disease, and choanal atresia with multiple congenital anomalies: CHARGE association.
Krivenki is a doctor of audiology student at the University of Tennessee who is conducting research on the vestibulo-ocular reflex in CHARGE syndrome. For some patients with specific types of hearing loss a surgically implanted hearing device may be advised. A more general observation has been that the acquisition of symbolic communication is highly correlated with successful audiologic intervention -regardless of the degree of hearing loss.
Patience and perseverance are essential-and are greatly appreciated by parents who typically rate hearing loss as their child's most significant disability.
