The Auditory Ossicles01:11

The Auditory Ossicles

1.8K
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

8.7K
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 Cochlea01:13

The Cochlea

45.6K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Prosthodontics

Background:

  • Auricular defects, resulting from trauma, congenital issues, or cancer, cause significant disfigurement and psychological distress.
  • Rehabilitation is challenging, particularly for bilateral defects, and surgical options may not suit all patients.
  • Custom-made auricular prostheses offer a viable reconstructive solution, enhancing social acceptance and self-esteem.

Observation:

  • This case report details an innovative, multidisciplinary technique for rehabilitating a patient with auricular defects, mixed hearing loss, and bilateral microtia.
  • A functional auricular prosthesis was successfully created and fitted for the patient.
  • The treatment prioritized patient satisfaction, comfort, and cost-effectiveness.

Findings:

  • The multidisciplinary approach successfully restored the auricular structure, addressing both aesthetic and functional concerns.
  • The custom auricular prosthesis led to improved social acceptance and psychological well-being for the patient.
  • Early rehabilitation with prosthetics is crucial for physical and psychological healing.

Implications:

  • This technique provides a valuable alternative for patients unsuitable for surgical ear reconstruction.
  • It highlights the importance of a multidisciplinary team in managing complex auricular defects.
  • Custom auricular prostheses can significantly enhance quality of life for individuals with ear loss or malformation.
