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
Pediatric Emergency Medicine

Background:

Foreign bodies (FB) in the external auditory canal represent a common otolaryngologic presentation.
Prompt management is essential to prevent secondary complications such as infection or hearing impairment.

Purpose of the Study:

To characterize the types of foreign bodies encountered in the external auditory canal.
To identify associated complications and demographic patterns of affected patients.

Main Methods:

A hospital-based descriptive study was conducted over 3 years and 5 months.
Data were collected from 126 patients presenting with foreign bodies in the ear.
All cases were managed by an Ear, Nose, and Throat (ENT) specialist.

Main Results:

The majority of cases (63.49%) involved children under five years of age.
The male to female ratio was 1.33:1, with most foreign bodies located in the right ear.
Most patients presented within 24 hours, and complications were infrequent; management often required local or no anesthesia.

Conclusions:

Children under five years are the most affected demographic for external auditory canal foreign bodies.
Expertise in instrumentation and skillful removal by an ENT specialist are key to minimizing complications.
