ASHA Clinical Competence in Audiology - Test Reviews Sample Questions

Which type of presbycusis is due to the degeneration of the sensory hair cells?

Correct Answer:
sensory.


sensory presbycusis: sensory presbycusis, one of the most common types of age-related hearing loss, specifically refers to the degeneration of sensory hair cells in the cochlea of the inner ear. these sensory hair cells are critical for converting sound waves into electrical signals that are sent to the brain. in sensory presbycusis, it is primarily the cells located near the basal turn of the cochlea that are affected. this part of the cochlea is crucial for hearing higher frequencies, which is why individuals with sensory presbycusis often first lose their ability to hear high-pitched sounds.

the progression of sensory presbycusis can also lead to atrophy of the spiral ganglion neurons, which are responsible for transmitting auditory signals from the hair cells to the brain. the loss of these neurons can exacerbate hearing difficulties, making it harder for individuals to understand speech, especially in noisy environments. the degeneration is typically gradual and affects both ears symmetrically, contributing to the overall decline in auditory sensitivity associated with aging.

other types of presbycusis: while sensory presbycusis focuses on the hair cells, other types of presbycusis have different pathologies. for example, neural presbycusis involves the degeneration of nerve fibers in the cochlea, metabolic (or strial) presbycusis affects the stria vascularis which is responsible for maintaining the ionic composition of the fluids in the inner ear, and mechanical (or cochlear conductive) presbycusis is related to changes in the mechanical properties of the basilar membrane. each type impacts hearing in different ways, contributing to the complexity of diagnosing and treating hearing loss in elderly patients.

understanding the specific type of presbycusis is crucial for developing targeted treatment strategies. for sensory presbycusis, interventions may focus on enhancing the amplification of sounds or using cochlear implants to bypass the damaged hair cells, whereas other types might require different approaches. early detection and tailored interventions can help mitigate the impact of hearing loss on the quality of life among the elderly.
