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...

Context:

Microtia is a congenital condition characterized by underdeveloped external ears.
Concha-type microtia specifically affects the conchal bowl, posing unique reconstruction challenges.
Current reconstructive techniques aim to restore both form and function.

Purpose:

To evaluate the efficacy of a two-staged auricular reconstruction technique for concha-type microtia.
To assess the aesthetic outcomes and symmetry achieved with this method.
To determine the suitability of autologous cartilage frameworks for this procedure.

Summary:

A two-staged surgical approach was employed for 13 patients (14 ears) with concha-type microtia.
The first stage involved fabricating and implanting an autologous cartilage auricular framework.
The second stage focused on ear elevation and establishing the cranio-auricle angle.

Impact:

The two-staged method provides satisfactory aesthetic results and symmetry with contralateral ears.
This technique offers an ideal solution for auricular reconstruction in concha-type microtia.
The study contributes to improved surgical strategies for congenital ear deformities.
