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...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Summary

Isolated malleus handle fractures, though rare, can occur after digital ear manipulation. Prompt diagnosis via otomicroscopy and CT scans is crucial for appropriate management of this ossicular injury.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Surgical Case Series

Background:

  • Isolated malleus fracture is an uncommon ossicular injury.
  • Fewer than 80 cases have been documented in medical literature.
  • This study focuses on malleus handle fractures, a specific type of this rare injury.

Observation:

  • A case series of three patients with isolated malleus handle fractures is presented.
  • Patients reported sudden hearing loss and aural fullness after digital manipulation of the external auditory canal.
  • Otomicroscopy revealed malleus fractures with abnormal distal malleus movement during pneumatic otoscopy.

Findings:

  • High-resolution CT scans with multiplanar reconstruction confirmed malleus fractures and displacement.
  • Conservative treatment was employed for one patient.
  • Two patients underwent ossiculoplasty for their malleus handle fractures.

Implications:

  • Malleus handle fracture should be suspected in cases of sudden hearing loss and aural fullness following digital ear canal manipulation.
  • Accurate diagnosis relies on otomicroscopy and advanced imaging like CT scans.
  • Treatment strategies range from conservative management to surgical ossiculoplasty.
