Insights

This study establishes normative cervical vestibular evoked myogenic potential (c-VEMP) values for children, finding responses comparable between air and bone conduction. These findings support bone conduction as a viable alternative for vestibular testing in pediatric populations.

Area of Science:

  • Neuroscience
  • Audiology
  • Vestibular System Physiology

Background:

  • Cervical vestibular evoked myogenic potentials (c-VEMPs) assess otolith function.
  • Normative data for c-VEMPs in children, particularly comparing air conduction (AC) and bone conduction (BC) stimulation, are limited.
  • Understanding age- and sex-specific variations is crucial for accurate clinical interpretation.

Purpose of the Study:

  • To characterize c-VEMPs using both AC and BC in healthy children.
  • To compare pediatric c-VEMP responses with those of adults.
  • To establish normative age- and sex-specific values for pediatric c-VEMPs.

Main Methods:

  • An observational study involving 118 healthy children and 41 healthy adults.
  • c-VEMPs were recorded using both AC and BC stimulation.
  • Responses were normalized to individual EMG traces, and amplitude ratios were modeled using the Royston-Wright method.

Main Results:

  • In children, AC and BC c-VEMP amplitude ratios were correlated and not significantly different.
  • Amplitude ratios were higher in males than females for both AC and BC.
  • Children exhibited significantly higher amplitude ratios than adults for both AC and BC stimulation.

Conclusions:

  • The study provides age- and sex-specific normative data for pediatric AC and BC c-VEMPs.
  • c-VEMP responses are equally effective with AC and BC stimulation in children up to 15 years.
  • BC stimulation is a valid alternative for vestibular otolith testing in children, especially with AC disorders.

Equilibrium and Balance01:15

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

The Vestibular System01:29

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Anatomy of the Ear01:16

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

The Auditory Ossicles01:11

The Auditory Ossicles

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...
