Facial symmetry impacts attractiveness, especially for microtia patients. Tissue engineering offers a promising, less invasive approach to ear reconstruction, improving aesthetic and functional outcomes.

Area of Science:

Biomedical Engineering
Regenerative Medicine
Plastic Surgery

Background:

Microtia, a congenital ear defect, causes psychosocial distress and challenges with current treatments like prostheses and the Nagata technique.
Existing treatments for microtia have limitations, including aesthetic issues, invasiveness, and surgical risks.
Facial symmetry is crucial for attractiveness, making ear reconstruction vital for patients with microtia.

Purpose of the Study:

To explore novel tissue engineering strategies for microtia treatment.
To discuss advancements in scaffold fabrication and cellular integration for auricular reconstruction.
To highlight innovative methodologies for improved aesthetic and functional outcomes in microtia repair.

Main Methods:

Reviewing current microtia treatments and their limitations.

Keywords:

Biodevices Microtia Nagata surgery Regenerative medicine Tissue engineering Translational medicine
