Hearing Loss : the Otolaryngologist's Guide to Amplification.

Intro -- 1 Why Should I Use Hearing Aids: Talking to the Patient About Hearing Loss WILLIAM LUXFORD, M.D. SERGEI KOCHKIN, PH.D.   Two groups of users are represented by the "I" in the title "Why should I use hearing aids?" The first group consists of hearing professionals: otolaryngologists, audiologists, and hearing aid dispensers who identify and care for patients with hearing loss. The second group consists of the consumers: patients, both adults and children, who would benefit from using hearing aids -- 2 Review of Audiometry MICHAEL J. NILSSON, PH.D. MICHELLE L. HICKS, PH.D.   The Purpose of Audiometric Testing The purpose of audiometric testing is to determine the presence and degree of hearing loss and the site of lesion. Hearing loss is defined as a frequency-dependent loss of sensitivity to soft sounds (typically tones) relative to expected normal sensitivity as reported by the audiogram. Normal hearing sensitivity across frequency is defined for young adults by the American National Stand -- 3 Hearing Aid Types DAVID M. BARRS, M.D.   Hearing Aids The otolaryngologist is often the initial contact for a patient who has questions about hearing aids. It is important, therefore, that the physician be familiar with the types of hearing aids and current hearing aid technology. The potential hearing aid market in the United States is at least 30 million individuals (Kochkin, 2001 -- National Institute on Deafness and Other Communication Disorders, 2008). Of this group, only approximately 20%.

4 Subjective and Objective Measures of Hearing Aid Performance STEPHEN J. SANDERS, AU.D. JOHN R. COLEMAN, AU.D.   Introduction Today's hearing instruments are increasingly complex with many programming options available across multiple channels. This chapter reviews the subjective and objective measures used to assess hearing and performance. Subjective Measurements of Hearing Aid Performance In the early days of amplification devices for hearing loss, verification of a beneficial or positive ou -- 5 Hearing Aid Candidacy in Adults MARCIA RAGGIO, PH.D.   Adult Hearing Aid Candidacy With dozens of hearing aid manufacturers, and hundreds of hearing aid possibilities, choosing the best hearing aid for a patient can be a challenging task. On the other hand, nearly all of today's digital hearing aids contain complex integrated circuits that allow for elaborate digital signal processing, while providing great flexibility for fitting essentially any hearing loss. Before any hearing aid choices ca -- 6 Verification of Hearing Aid Fitting DAVID FABRY, PH.D.   According to Hearing Industries Association (2008) figures, digital hearing aids represent over 95% of the total hearing aids dispensed in the United States. Although digital technology affords access to unparalleled technology for noise cancellation, multiple-channel compression, adaptive directionality, and adaptive feedback cancellation, the primary advantage compared to analog devices is the sophisticated control over these features,.

7 Hearing Aid Amplification in Pediatric Patients MARGARET E. WINTER, M.S., CCC-A   A fundamental principle of pediatric hearing care is that no child is too young for a hearing test. A fundamental corollary of this principle is that, when a potentially handicapping hearing loss is discovered, even if it is within the first few weeks of life, immediate steps toward auditory habilitation are essential. The ultimate linguistic success of a child with hearing loss rests less on early identification -- 8 Medical Reasons for Hearing Aid Failure M. JENNIFER DEREBERY, M.D.   It is the rare patient who looks forward to wearing hearing aids. The most common barriers to successful amplification are patient denial, patient reluctance and cost. Cosmetic concerns, unrealistic expectations, patient dexterity, and level of hearing loss are also significant issues that the physician and audiologist/dispenser must confront in virtually every patient who receives a recommendation for amplification. In contr -- 9 The Management of Tinnitus in the Hearing-Impaired Patient JOHN W. HOUSE, M.D.   Tinnitus is defined as a sensation of sound in the ears or head. The tinnitus may be unilateral, bilateral, or located in the head. The patient describes it as ringing, roaring, bells, crickets, seashell sound, like escaping steam, and so on. The patient's tinnitus maybe present constantly or intermittently. In discussing tinnitus, it is important to understand that tinnitus is a symptom and not a disease. Therefo.

10 The Role of Hearing Aids in the Management of Tinnitus PAWEL J. JASTREBOFF, PH.D., SC.D., M.B.A. MARGARET M. JASTREBOFF, PH.D.   A perception of sound without the presence of a physical sound that can be linked to this perception is known as tinnitus. Therefore, tinnitus is a phantom auditory perception, analogous to phantom pain or limb phenomena. Typically, it is described as ringing, buzzing, hissing, humming, whistling, roaring sound, perceived in the ears or the head. The majority of peo -- 11 Nutritional Supplements for the Hearing-Impaired Patient MICHAEL J. A. ROBB, M.D MICHAEL D. SEIDMAN, M.D.   Introduction Nutraceutical is defined as "food, or parts of food, that provide medical or health benefits, including the prevention and treatment of disease" (DeFelice, 2002 -- Kalra, 2003). The purpose of this chapter is to review the scientific evidence of select nutraceuticals that suggest these natural compounds either help prevent mitochondrial dysfunction and/or possess anti-inflamm -- 12 Implantable Hearing Devices WILLIAM H. SLATTERY, III, M.D.   It is estimated that 32 million Americans have a hearing loss severe enough to cause problems with communication. The severity of this loss ranges from mild, in which the individual may have difficulty only when significant background noise is present, to a profound loss in which even in the quietest situation the patient is unable to understand and communicate. Most hearing loss is sensorineural in nature. Less than 10% of the hear.

13 Assistive Listening Devices RANDY DRULLINGER   ALDs and the Modern Practice Assistive listening devices (ALDs) have been an overlooked and underused tool in many practices. The hassle of deciding which items to carry, where to display them, and how to manage excess inventory has kept many practitioners from recognizing the benefits that ALDs can bring. Increasingly today, products in this category are being recognized as another component in treating hearing loss, along with hearing aids and -- 14 Hearing Aid Dispensing for the Otolaryngologist NEIL GIDDINGS, M.D.   "Marketing is what we do so we don't have to advertise." Marketing and advertising may be foreign concepts to the practitioner. Although beneficial to most business owners, it is the rare otolaryngology residency that devotes time to teaching the "business" of running a practice. In order to expand beyond simply servicing those patients noted in the office setting who require amplification, the shift from "marketing" to adv -- 15 Economics of Hearing Aid Dispensing BRAD VOLKMER, M.B.A.   Hearing aid dispensing can be a great business addition to the otolaryngology practice. A considered and thoughtful approach to the components required to successfully dispense hearing aids and the development of an operational model are critical to the successful undertaking of hearing aid dispensing. It is important for the otolaryngologist to understand all of the operational requirements and the related costs. Establishing up fron.

16 Lessons from the Real World MICHAEL VALENTE, PH.D.   Introduction Directing a professionally and financially successful Audiology practice in the current medical environment can present significant obstacles and challenges. Unlike a private practice where much of the energy may be focused on a profitable hearing aid segment, services provided in a medical environment include both rehabilitative (including hearing aid dispensing) and diagnostic procedures. Unfortunately, reimbursement for many.

This textbook is designed for otolaryngologists, both those in training as well as in practice, to enhance the basic knowledge of hearing aid mechanics and dispensing taught in residency programs. The text has informative chapters on special testing, real-ear measurements, the requirements of fitting the pediatric patient with hearing loss, as well as the patient with tinnitus and hearing loss that otolaryngologists can expect to see commonly in practice.
