The Auditory Ossicles

2.6K
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...

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...

Summary
This summary is machine-generated.

This study describes a rare case of isolated ear clicks, a type of objective tinnitus, in a 15-year-old boy. The patient exhibited voluntary control over the ear clicking, a novel finding in this condition.

Area of Science:

  • Neurology
  • Otolaryngology

Background:

  • Ear click is a rare form of objective tinnitus.
  • It is often associated with palatal tremor/myoclonus (PT).

Observation:

  • A 15-year-old male experienced constant bilateral ear clicking for four years.
  • The ear clicking was audible, could be voluntarily controlled briefly, and was entrainable by an examiner.
  • No visible palatal movement or eardrum activity was observed; brain MRI was normal.

Findings:

  • The case presents as isolated ear clicks with partial voluntary control.
  • This suggests a potential new subcategory within the spectrum of palatal myoclonus.

Implications:

  • This case expands the understanding of objective tinnitus and its variations.
  • Further research may clarify the pathophysiology of isolated, voluntarily controlled ear clicks.
