In some cases, a cochlear implant can be used to restore hearing to those suffering from severe to minor hearing loss. A diagnosis of congenital hearing loss is often made when a baby fails to meet specific developmental milestones. If congenital hearing loss is suspected at a young age, a physical will examine the child to determine if there are any structural issues with the ear. Infections, such as bacterial meningitis, or cranial injury sustained during labor and delivery can result in damage to the inner ear.
Hereditary conditions, such as albinism and Hurler's syndrome, can contribute to a loss of hearing.
An auditory brain stem response (ABSR) exam involves the use of electrode patches to evaluate the efficiency of the auditory nerve's response to sound.
Treatment for congenital hearing loss is dependent on the child's health and the reason for the hearing loss. Complications associated with congenital hearing loss include delayed communicative development and its accompanying emotional impact. Of children with sensorineural hearing loss of any type, between 11-41% of them have inner abnormalities seen on CT.
Before we start talking about individual syndromes, inherited deafness is usually symmetrical and bilateral, nearly always sensorineural, and usually more severe at high frequencies. Barakat syndrome, also known as HDR syndrome, is an inherited condition characterized by hypoparathyroidism, sensorineural deafness and renal disease (Barakat et al in 1977).
Large Vestibular Aqueduct Syndrome (LVAS) also known as EVA (enlarged vestibular aqueduct). About 60% of mutations in the SLC26A4 gene known to cause Pendred syndrome can be detected with genetic testing. Although the SMA's are not generally associated with hearing symptoms, a recent report suggests that the disorder caused by a mutation in TRPV4 can induce a neuropathy as well as hearing loss (Oonk et al, 2014).
Waardenburg syndrome (WS) is a largely autosomal dominant disorder characterised by pigmentary anomalies of the skin, hairs, eyes and various defects of other neural crest derived tissues (Read and Newton, 1997). The displacement of the canthus, dystropia cantorum, is the distinguishing feature between WS1 (has it) and WS2 (doesn't have it). Wolfram Syndrome, first described in 1938, is also known as DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, deafness). Delayed onset of hearing loss is common -- infants with CMV and normal hearing at birth should be monitored for 6 years. There are also some deformities of the membranous labyrinth -- as for example the very common Schiebe deformity (pars inferior -- cochlea and saccule). One would think that the VEMP test would be a good method of detecting the Schiebe deformity, as the VEMP is sensitive to saccule disturbances. Unusually sized openings between the inner ear and the brain (internal auditory meatus) are usually associated with other bone abnormalities (surprise !). Li Y1, Yang J, Liu J, Wu H.Restudy of malformations of the internal auditory meatus, cochlear nerve canal and cochlear nerve. Oonk AM1, Ekker MS2, Huygen PL3, Kunst HP3, Kremer H4, Schelhaas JJ5, Pennings RJ3.] Intrafamilial Variable Hearing Loss in TRPV4 Induced Spinal Muscular Atrophy. Aural atresia is an underdeveloped external ear (auditory) canal, eardrum, and middle ear bones, causing hearing loss. Although the outer and middle ear anatomy is affected in aural atresia, most children have a normally functioning inner ear (cochlea and auditory nerve). Aural atresia is often associated with microtia, a congenital condition in which the outer ear is small, malformed, or missing.
While some children may have an ear canal, there is no eardrum and the middle ear is not properly formed. A baby born with aural atresia or aural stenosis needs to see an Audiologist for specialized hearing testing and be closely monitored by an Otolaryngologist (Ear, Nose and Throat Surgeon). Otitis media is an inflammation in the middle ear (the area behind the eardrum) that is usually associated with the buildup of fluid.
The Eustachian tube, a passage between the middle ear and the back of the throat, is smaller and more horizontal in children as compared to adults. Three tiny bones (ossicles) in the middle ear carry sound vibrations from the eardrum to the inner ear. When fluid is present behind the eardrum, the eardrum may become retracted into the middle ear space.
Generally, this type of hearing loss is conductive and most often temporary and fluctuating. If a hearing loss exists, a child does not get the full benefit of language learning experiences. Middle ear fluid without infection presents a special problem because symptoms of pain and fever are usually not present.
An audiologist’s evaluation will assess the severity of any hearing impairment, and will indicate if a middle ear disorder is present. A speech-language pathologist measures your child’s speech and language skills and can provide remediation programs as needed. Parents should not be afraid to let their instincts guide them in requesting or independently arranging for further evaluation if they are concerned about their children’s health or development.
At Clear Choice Hearing and Balance we provide a full range of pediatric evaluations to assess hearing loss in toddlers and children. Otoacoustic Emissions (OAE) is the primary screening tool utilized by hospitals for the Newborn Hearing Screening. Tympanometry and Acoustic reflexes are tools used to assess middle ear function and identify the presence of fluid (effusion), negative middle ear pressure, ossicular chain (middle ear bones) disruption, and tympanic membrane (ear drum) perforation. Behavioral Tests: Play Audiometry utilized from approximately three years to five years of age-is a test where the child is conditioned to respond to sounds with a play task such as placing a block in a bucket after hearing tones through head phones. Standard Audiometry utilized from five years of age and beyond-is a test where the child is instructed to raise their hand every time they hear the tone through head phones.

Embryologic Origins of Hearing Loss:What’s the relationship between prenatal development and congenital and progressive hearing impairment? Embryologic Origins of Hearing LossWhat’s the relationship between prenatal development and congenital and progressive hearing impairment? You will receive an email whenever this article is corrected, updated, or cited in the literature. Carol Runyan: As complicated as the ear structure and function are, do you have any hypotheses about why it is?
Bridget Gonzalez: Is there more risk of spinal meningitis, the younger the infant is, due to developmental ossification of the temporal bone?

Dodson: Definitely the risk of meningitis is higher from otitis media in infants and children who have developmental anomalies of the inner ear that lead to direct communication between the ear and brain, commonly from a patent cochlear aqueduct or the like. Vaibhavi Dharkar: What is the relationship between hearing loss and skin disease, is this in any way related to the fact that both the skin and sensory cells are a product of the ectoderm? Gonzalez: Hi, Just to clarify, are you saying that you can occasionally see a congenital cholesteatoma with Treacher-Collins, Goldenhars or Omenn’s syndrome?
Dodson: We see congenital cholesteatoma more frequently if there is aural atresia (meaning the canal is underdeveloped), because the epithelium that lines the ear canal may be trapped inside and not be able to get out.
Margo McNiven: Is a pre-auricular or post-auricular tag or cyst considered a marker for hearing loss?
Dodson: There is a small association of an isolated pit or tag with hearing loss apart from BOR. Christine Cook: What is the best practice for follow-up with children who have been diagnosed with meningitis? Dodson: Definitely, part of the risk of hearing loss depends on the type of meningitis—it’s probably greatest with streptococcus pneumoniae, which causes a lot of inflammatory damage. Cook: If the child’s hearing is normal, what would you recommend for continued testing—every three months through the first year? Dodson: I would say at a minimum, six-month intervals, but for children whose progression I am particularly concerned about (because many of these babies also receive antibiotics that may be ototoxic), I might see them back at three-month intervals for a year. Dodson: Familiarity with embryology is really helpful in everyday clinical practice, particularly if you work with the pediatric population. Mary Violanti: Regarding preauricular pits, can a physician tell by examination if it’s a blind pit or one with potential for infection? Dodson: It is usually difficult to tell early on how deep and in which direction the pit is going. Alicia White: I had a patient that had bilateral anotia and also had bilateral absent cochlear nerves. Dodson: Usually in kids we want to wait until their bone thickness exceeds 4 mm so we can implant a 4-mm osseointegrated implant.
Leslie Heuser: Can you have just a first branchial cleft cyst that is not associated with hearing loss or syndromes? A Case Study of an Emerging Community-Based Early Hearing Detection and Intervention Program: Part II.
In children who are deemed likely to have an inner ear abnormality and who are sent for MRI scan, about 40% have abnormalities (McClay et al, 2008). In other words, although there are many many more papers about genetic syndromes than non-syndrome deafness, and lots more text on this page, these conditions that are the subject of so much discussion, are just a little piece to the big genetic hearing loss puzzle.
WS1 is mostly caused by PAX3 mutations, while MITF, SNAI2, and SOX10 mutations are associated with WS2. Mutations of EDNRB, EDN3 and SOX10 genes are responsible for Waardenburg syndrome type IV (Otreba et al, 2013) . According to Plantinga et al (2008), all patients had similar sensorineural hearing loss with a gently downsloping pattern.
The organ of Corti, particularly the basal turn of the cochlea and adjacent ganglion cells, is affected most prominently. Ther reason is that these deformities cannot be diagnosed on CT scan, as CT scans are not able to define abnormalities of the membranous labyrinth. Screening of SLC26A4, FOXI1, KCNJ10, and GJB2 in Bilateral Deafness Patients with Inner Ear Malformation. The majority of patients born with microtia are affected only on one side (unilateral microtia and aural atresia), although approximately 10% are affected on both sides (bilateral microtia and aural atresia).
Others may have a very small ear canal with associated hearing loss, called aural stenosis. Early diagnosis of hearing loss in children is critical for proper speech and language development. At one extreme is a single short period of thin, clear, noninfected fluid without any pain or fever but with a slight decrease in hearing ability. Seventy-five percent of children experience at least one episode of otitis media by their third birthday. When fluid is present, the vibrations are not transmitted efficiently from the eardrum through the ossicles. Because of this it  cannot vibrate as efficiently and conduct sound to the tiny bones in the middle ear. However when otitis media occurs over and over again, damage to the eardrum, the bones of the ear, or even the hearing nerve can occur and cause a permanent hearing loss.
Ear infections require immediate attention, most likely from a pediatrician or otolaryngologist (ear physician). This may be at any time in one’s life, perhaps as a result of a disease, a condition, or an injury. Our available tests include play audiometry, tympanometry, acoustic reflex, and otoacoustic emissions (OAE). A soft probe is placed in the child’s ear which delivers a sound to the ear and in return measures the echo response sounds emitted from the inner ear.
A soft probe is placed in the ear which delivers a safe measurable amount of sound and pressure.
At birth, theoretically there should be complete ossification of the middle ear cavity (albeit quite thin) that helps separate the ear and brain. I don’t think that congenital cholesteatoma of the middle ear has an increased associated with these syndromes, but definitely of the ear canal.
Or is hearing loss only a concern when the tag or cyst is seen in conjunction with BOR [branchiootorenal syndrome]? Whenever I see a child with a pit or tag that appears nonsyndromic, I take a detailed history and physical and get an audiogram just to be sure.
I always like to get a hearing test as soon as the child is stable, and preferably before discharge home from the meningitis admit. There are no hard-and-fast guidelines, but following the guidelines set forth by the Joint Committee on Infant Hearing for babies with risk factors, until the age of 3 is a good general rule to follow for the postnatal infections and ototoxicitiy. If you work with syndromic or medically complicated patients, your knowledge of embryology when you evaluate their ear, head and neck can make you suspicious for other associated conditions that might not be readily apparent. Sometimes it is obvious that the pit is really just a blind-ended depression, but if there is clearly a tract, the best option is observation.
From an embryologic development point of view, could there be any relationship between the two abnormalities?
Probably the etiology involves a global insult to the nervous system and to the branchial arches at the early stages of development (Hillocks of His completely absent for the anotia) and the neurosensory otic placode not making any connection with the developing brain.
I have heard many conflicting reports about the best time to begin the surgical process of canal reconstruction if it is the parental choice.

A large part of the discussion involves whether it is bilateral or unilateral and if the patient is a “good” candidate. She had had bilateral [bone-anchored hearing aids] with a band, and they were simply waiting till she was “big” enough for the surgery. It is approved in kids 5 and up, but if the child has good bone thickness you could do earlier, although insurance would probably not cover it.
Marker analysis enables identification of the region of the genome where the disease gene lies. Of course, this does not mean that 40% of all deaf children will have MRI abnormalties, but rather 40% of those who are thought by their doctors to have an MRI abnormality, and who are sent for an MRI, have MRI abnormalities. It is associated with congenital anomalies of all three parts of the ear (external, middle and inner ear) as well as the IAC and vestibular aqueduct (see below). Roughly two thirds of the Turner's population has hearing loss, about evenly split between sensorineural and conductive types (Ingeborg et al, 2005). More than 100 different disease-causing mutations have been reported in many ethnic groups(Chen et al, 2010). Hearing loss is most notable with higher frequencies, while low-frequency hearing is relatively preserved. Children acquire a significant amount of language from listening to the speech and language of others. Young children are more prone to this condition than adults, due to the configuration of the eustachian tube.
Almost one-half of these children will have three or more ear infections during their first 3 years of life (2). Until the Eustachian tube changes in size and angle as the child grows, children are more susceptible to middle ear infections. During this time, the child may miss out on some of the information that can influence speech and language development. If your child has frequent infections or chronic fluid in the middle ear, two additional specialists should be consulted: an audiologist and a speech-language pathologist. Her clinical and research interests include pediatric otolaryngology, congenital and hereditary hearing loss, unilateral hearing loss, vestibular disorders, tinnitus and pediatric sinusitis, and she has published extensively on pediatric and genetic hearing loss, risk factors associated with unilateral and bilateral hearing loss, and nonsyndromic mitochondrial deafness. I have seen many children born where the mother was unaware of her pregnancy and, as a result, had no prenatal care and abuse of alcohol, drugs, etc.
Sadly, most of this development takes place before women are aware they may be pregnant and so it is highly susceptible to teratogens and environmental influences.
However, infants younger than 3 months are at greater risk, in general, for sepsis or generalized spread from infections due to the immaturity of the immune system, and bacteria can travel via preformed pathways (along veins, etc.) to cause meningitis.
These babies typically have several other risk factors known to be associated with hearing loss as well (low birth weights, prematurity and NICU stays), so we would certainly pay close attention to newborn hearing screening and provide appropriate follow-up during infancy. If it cannot be done in the inpatient setting, they should see someone within a week or two after discharge. For instance, if you are evaluating an infant who failed the newborn hearing test, you might be the first to note small branchial cysts in the neck and preauricular pits, and that would alert you to evaluate their kidneys for BOR syndrome, which is potentially life-saving. In other words, it means that the abnormal rate for clinicians at the location where this study was done (Dallas), is about 40%. It seems likely that outside of academic settings, cookie-bite hearing patterns are even more likely to be associated with inherited hearing loss. Renal disease includes nephrotic syndrome, renal dysplasia, hypoplasia or aplasia, chronic renal failure, hematuria, proteinuria and others.
Pendred is associated with large vestibular aqueduct syndrome (see above) as well as Mondini (see below). The SOX10 mutation is also involved in the Kallman syndrome with deafness (Pingault et al, 2015).
If a hearing loss is present, especially during the first few years of life, the child is deprived much of the language learning opportunity.
Health costs for otitis media in the United States have been reported to be $3 billion to $5 billion per year (3). Physiologic tests are those which rely upon non-behavioral responses from the child’s auditory system. This test not only provides very valuable information for hospital screening but is also routinely utilized in clinical settings.
If there is bilateral severe-to-profound hearing loss, you want to be able to proceed with cochlear implantation sooner rather than later—before the inflammatory changes cause ossification within the cochlea. The first is a more straightforward “duplication” of the ear canal, the second is a more winding tract through the parotid salivary gland and into the neck. Note that many persons with thyroid problems have Meniere's disease (Brenner et al, 2004), and thus LVAS, Meniere's and Pendred syndrome may all be interconnected.
The MITF (microphthalmia transcription factor) is related to the melanogenesis process (i.e. There are many different causes of hearing loss in children including otitis media (middle ear infections), congenital (present at birth) and acquired. The problem with atresiaplasty is that over time, the canal tends to stenose down and never exfoliates normally—so it generally requires lifelong cleaning and has perhaps not the greatest hearing result long-term. We place the implant and keep it covered (nothing protruding through the skin) for three to six months to allow the titanium to bond with the bone. Each of these can have detrimental effects on language acquisition and communication if left unidentified and untreated.
If excellent hearing is really the goal, osseointegrated implants probably work better, but the decision depends on many factors. In the second stage, we place the “abutment,” which basically screws into the implant in the bone and protrudes out of the bone to allow the processor to clip on. When they clip on the processor, they get direct bone conduction on that side and excellent hearing results for conductive losses or single-sided profound deafness. Irreversible hearing losses can be evaluated and fitted with the most appropriate hearing aids. Diagnosis of hearing loss and fitting hearing aids on children can be a special challenge, but our staff’s experience allows us to provide quality care.
Our audiologists are some of the most experienced pediatric audiologists with extensive experience with hearing care for kids.
