Tinnitus, a condition that causes ringing or buzzing in the ears, can be treated with the help of hearing aids. Untreated hearing loss can affect the ability to understand speech and can negatively impact social and emotional well-being. If you answered yes to any of these questions, you may have a hearing loss and should have your hearing tested. Conductive hearing loss occurs when sound waves are not conducted properly from the outer ear through to the middle ear. Mixed hearing loss is a combination of Sensorineural hearing loss and Conductive hearing loss indicating problems with the outer, middle, and inner ear. BergerHenry ENT offers the safest and most advanced equipment and technology available today for the hearing impaired. This spring, on the eastern coast of the United States, we have not witnessed tree pollen spikes as we have in prior years.

Sensorineural hearing loss is the most common type of hearing loss, occurring in 23% of population older than 65 years of age. Infections, such as meningitis, are a common cause of hearing loss in children where it occurs in approximately 20% of those with streptococcus pneumoniae meningitis (Heckenberg et al 2011). Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise.
Children who are born prematurely or contract certain infections in utero are at a higher risk of hearing loss (Hille et al 2007, Roizen 2003). While very unusual, acoustic neuromas or metastatic cancer (particularly breast) can be a source of hearing loss. Sudden hearing loss (SHL) is defined as greater than 30 dB hearing reduction, over at least three contiguous frequencies, occurring over 72 hours or less.
Sensory presbyacusis is caused by loss of sensory elements in the basal (high-frequency) end of the cochlea with preservation of neurons. Cochlear conductive presbyacusis is caused by thickening of the basilar membrane caused by deposition of basophilic substance. Because presbycusis occurs in some individuals as they age but not in others, genetic or environmental factors must also play a role in its development (Liu & Yan 2007).


In conductive hearing loss, the second most common form of hearing loss, sound is not transmitted into the inner ear.
Images marked as copyright Northwestern University were developed with the support of a National Institutes of Health (NIH) grant to Northwestern University Dept. The American Hearing Research Foundation is a non-profit foundation that funds research into hearing loss and balance disorders related to the inner ear and is also committed to educating the public about these health issues. Central: Hearing loss caused by a problem along the pathway from the inner ear to the auditory region of the brain or in the brain itself.
You often have to ask people to repeat what they say because you can't quite hear them, especially in groups or when there is background noise. If you have any of these symptoms, contact one of our offices so you can be tested for hearing loss. The Better Hearing Institute states that 1 out of 10 Americans have a hearing loss – that’s more than 14,000,000 people nationwide!
Hearing loss in the older population has been linked to a contributor of depression due to feeling excluded and unable to communicate comfortably in social settings. While some sizes offer better amplification for different types of hearing loss, we can ensure you a comfortable fit with minimal visibility. We will advise and guide you through each step to improve your hearing and get you back to your daily life. The outer ear includes the auricle, the external auditory canal, and the lateral surface of the tympanic membrane (TM).
Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear damage). One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech.
Much research has focused on the detection of genetic causes of hearing loss, and many of them can now be diagnosed at an early age (Blanchard et al 2012, Dror & Avraham 2009, Kochhar et al 2007, Kokotas et al 2007, Robin et al 2005, Xing et al 2007). Risk factors that correlate with hearing loss in premature infants include hypoxia, mechanical ventilation, hyperbilirubinemia, very low birth weight, and the use of ototoxic medications. It occurs most frequently in the 30- to 60-year age group and affects males and females equally. These patients have symmetrical, high-frequency sensorineural hearing loss (as shown in Figure 3).


Medical conditions that are common in the elderly, such as diabetes and stroke, may also increase the risk of hearing loss with aging (Bainbridge et al 2010, Helzner et al 2005, Maia & Campos 2005, Schreiber et al 2010). Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, tympanosclerosis (as shown in Figure 4), external or middle ear infections (otitis externa or media), allergy with serous otitis media, trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane.
Depending on what type of hearing loss you may have, treatment options are available ranging from a simple wax cleaning, treating an infection or possibly hearing aids. The middle ear includes the medial surface of the TM, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve. These conditions are relatively common in premature infants, and the majority do not go on to develop hearing deficits. Hearing loss in adults surviving pneumococcal meningitis is associated with otitis and pneumococcal serotype. Race and sex differences in age-related hearing loss: the Health, Aging and Body Composition Study. The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals). The National Institute of Health reports that about 15 percent of Americans aged 20 to 69 have high frequency hearing loss related to occupational or leisure activities.
If the loss is minor, then avoidance of noise and ototoxic medications may be an appropriate treatment. Trauma is more likely to affect hearing in patients who suffer a temporal bone fracture or are older in age (Bergemalm, 2003). Because of occupational risk of noise induced hearing loss, there are government standards regulating allowable noise exposure.
People working before the mid 1960s may have been exposed to higher levels of noise where there were no laws mandating use of devices to protect hearing. Occasionally, persons with acquired deafness can be treated surgically with a surgically implanted device, a cochlear implant.
