The Auditory Ossicles

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...

Anatomy of the Ear

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...

Area of Science:

Otolaryngology
Medical Device Complications

Background:

Hearing aids are common assistive devices.
Custom molds are used for optimal fit and acoustic performance.

Observation:

Two rare cases of otologic complications from retained hearing aid mold impression material are presented.
Symptoms are dependent on the duration of material retention.

Findings:

Case 1: Chronic middle ear discharge and granulation tissue.
Case 2: Acute ear pain and dizziness.

Implications:

Retained impression material is a potential cause of otologic issues.
Standard otologic surgical techniques can safely manage these complications.
