  • Harrison's Internal Medicine Chapter 30. Disorders of Smell, Taste, and Hearing Smell The sense of smell determines the flavor and palatability of food and drink and serves, along with the trigeminal system, as a monitor of inhaled chemicals, including dangerous substances such as natural gas, smoke, and air pollutants. Olfactory dysfunction affects ~1% of people under age 60 and more than half of the population beyond this age. Definitions Smell is the perception of odor by the nose. Taste is the perception of salty, sweet, sour, or bitter by the tongue.

  • In the event that the hearing aid provides inadequate rehabilitation, cochlear implants may be appropriate. Criteria for implantation include severe to profound hearing loss with word recognition score ≤30% under best aided conditions. Worldwide, 20,000 deaf individuals (including 4000 children) have received cochlear implants. Cochlear implants are neural prostheses that convert sound energy to electrical energy and can be used to stimulate the auditory division of the eighth nerve directly.

  • The contribution of genetics to presbycusis (see below) is also becoming better understood. In addition to GJB2, several other nonsyndromic genes are associated with hearing loss that progresses with age. Sensitivity to aminoglycoside ototoxicity can be maternally transmitted through a mitochondrial mutation. Susceptibility to noise-induced hearing loss may also be genetically determined. There are 400 syndromic forms of hearing loss.

  • Presbycusis (age-associated hearing loss) is the most common cause of sensorineural hearing loss in adults. In the early stages, it is characterized by symmetric, gentle to sharply sloping high-frequency hearing loss. With progression, the hearing loss involves all frequencies. More importantly, the hearing impairment is associated with significant loss in clarity. There is a loss of discrimination for phonemes, recruitment (abnormal growth of loudness), and particular difficulty in understanding speech in noisy environments.

  • Approach to the Patient: Disorders of the Sense of Hearing The goal in the evaluation of a patient with auditory complaints is to determine (1) the nature of the hearing impairment (conductive vs. sensorineural vs. mixed), (2) the severity of the impairment (mild, moderate, severe, profound), (3) the anatomy of the impairment (external ear, middle ear, inner ear, or central auditory pathway), and (4) the etiology. The history should elicit characteristics of the hearing loss, including the duration of deafness, unilateral vs. bilateral involvement, nature of onset (sudden vs.

  • Disorders of the Sense of Hearing Hearing loss can result from disorders of the auricle, external auditory canal, middle ear, inner ear, or central auditory pathways (Fig. 30-4). In general, lesions in the auricle, external auditory canal, or middle ear cause conductive hearing losses, whereas lesions in the inner ear or eighth nerve cause sensorineural hearing losses. Figure 30-4 An algorithm for the approach to hearing loss.

  • The responses are measured in decibels. An audiogram is a plot of intensity in decibels of hearing threshold versus frequency. A decibel (dB) is equal to 20 times the logarithm of the ratio of the sound pressure required to achieve threshold in the patient to the sound pressure required to achieve threshold in a normal hearing person. Therefore, a change of 6 dB represents doubling of sound pressure, and a change of 20 dB represents a tenfold change in sound pressure.

  • "Hear" và "Listen". Câu hỏi về sự khác biệt của hai từ tiếng Anh này đã làm tôi khá bối rối khi sử dụng. Chúng ta dùng "hear" với những tiếng động đến tai chúng ta mặc dù không nhất thiết là chúng ta phải cố gắng lắng nghe những tiếng động đó. Tôi có thể nói 'They hear a strange noise in the middle of the night' - Họ nghe thấy một tiếng động lạ hồi nửa đêm. "Listen" được dùng để miêu tả việc lắng nghe, tập trung chú ý tới tiếng động đang diễn ra. Ví dụ:...

  • Disorders of the Sense of Taste Disorders of the sense of taste are caused by conditions that interfere with the access of the tastant to the receptor cells in the taste bud (transport loss), injure receptor cells (sensory loss), or damage gustatory afferent nerves and central gustatory pathways (neural loss) (Table 30-2). Transport gustatory losses result from xerostomia due to many causes, including Sjögren's syndrome, radiation therapy, heavy-metal intoxication, and bacterial colonization of the taste pore.
