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...

This two-stage microtia reconstruction method creates natural-looking ears. The technique reconstructs fine ear structures with rare complications, offering a promising solution for microtia.

Area of Science:

Plastic Surgery
Otolaryngology
Pediatric Surgery

Background:

Microtia reconstruction presents significant challenges in achieving natural ear contours.
Existing methods may not fully restore intricate ear structures.

Purpose of the Study:

To present a novel two-stage surgical technique for microtia reconstruction.
To achieve aesthetically pleasing and anatomically accurate reconstructed ears.

Main Methods:

Fabrication of a 3D cartilage framework in the first stage.
Elevation of skin and retroauricular fascial flaps for framework coverage.
Reconstruction of the crus, tragus, and conchal cavity in the second stage.

Main Results:

Published on: May 23, 2021

Successfully reconstructed ears in 68 pediatric patients (ages 5-17).

Achieved a 3-dimensional ear configuration with cranioauricular angles similar to the unaffected ear.

Demonstrated a low complication rate.

Conclusions:

The two-stage ear reconstruction is a straightforward and effective method for microtia.
This technique reliably restores the complex anatomy of the ear with good cosmetic outcomes.
