The Auditory Ossicles

3.1K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Nervous System

3.4K
The nervous system coordinates body functions through its complex network of nerve cells, enabling sensation and movement. It is divided into two primary parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and the spinal cord. The brain acts as the body's control center, processing sensory information and coordinating responses. The spinal cord functions as a major signaling pathway for the brain and the rest of the body.

Summary

Otitis media negatively impacts children's auditory processing and brainstem responses, even after tube surgery. Early intervention is crucial for auditory development in children with a history of ear infections.

Area of Science:

  • Neuroscience
  • Audiology
  • Pediatrics

Background:

  • Otitis media is a common childhood infection.
  • It can affect auditory development and central auditory nervous system function.
  • Bilateral tubes placement is a common surgical intervention.

Purpose of the Study:

  • To analyze central auditory nervous system function in children with a history of otitis media and bilateral tubes placement.
  • To compare behavioral and electrophysiological measures between children with and without a history of otitis media.

Main Methods:

  • Two groups of children (8-14 years): control (n=40) and experimental (n=50) with otitis media history and tube surgery.
  • Evaluations included audiological, behavioral (dichotic digits, SSI, GIN, frequency pattern), and electrophysiological tests (ABR, FFR, LLAEP).

Main Results:

  • Children with otitis media history showed significantly poorer performance in all auditory abilities.
  • Electrophysiological tests revealed latency delays and reduced amplitudes in ABR, LLAEP, and FFR for the experimental group.

Conclusions:

  • Otitis media has a demonstrable negative effect on auditory abilities and electrophysiological measures in children.
  • These deficits persist even after surgical intervention with bilateral tubes.
