The Auditory Ossicles01:11

The Auditory Ossicles

2.1K
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...

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...

Equilibrium and Balance01:15

Equilibrium and Balance

5.1K
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...

The Vestibular System01:29

The Vestibular System

40.2K
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.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Trauma Surgery

Background:

  • Traumatic ossicular dislocation is a known otolaryngologic injury.
  • Stapes luxation, specifically displacement into the vestibule, is exceptionally rare.

Purpose of the Study:

  • To report a rare case of traumatic stapes luxation into the vestibule.
  • To describe the successful surgical management and outcomes of this rare injury.

Main Methods:

  • A 31-year-old female with sudden vertigo and hearing loss after ear trauma underwent temporal bone CT.
  • Exploratory tympanotomy revealed incudostapedial joint separation and stapes footplate luxation into the vestibule.
  • Stapedectomy was performed, followed by reconstruction with a piston wire, and the footplate was sealed.

Main Results:

  • Post-surgery, vertigo rapidly subsided, and hearing improved to normal ranges.
  • High-frequency hearing loss persisted, potentially due to inner ear damage or surgical manipulation.
  • The patient experienced a successful repair of the traumatic stapes luxation.

Conclusions:

  • This case demonstrates the successful surgical repair of traumatic stapes luxation into the vestibule.
  • The described technique provides a potential treatment approach for similar rare otologic injuries.
  • Early diagnosis and surgical intervention are crucial for favorable outcomes in traumatic stapes luxation.
