[Management of patients with complex ear deformities]

Area of Science:

• Plastic Surgery
• Otolaryngology
• Biomedical Engineering

Background:

• Complex ear reconstruction addresses microtia, a congenital condition often linked to hearing impairments.
• Management of associated hearing disorders is prioritized over external ear reconstruction.
• Current auricular reconstruction techniques involve subcutaneous implantation of autologous cartilage or allogeneic implants.

Purpose of the Study:

• To review current methodologies for auricular reconstruction in patients with microtia.
• To compare the outcomes and risks associated with autologous cartilage versus allogeneic implants.
• To evaluate the impact of ear reconstruction on patients' psychosocial well-being.

Main Methods:

• Subcutaneous implantation of either autologous cartilage grafts or allogeneic implants.
• Surgical expertise required for autologous reconstruction involves harvesting rib cartilage.
• Comparison of complication rates, focusing on implant exposure risks.

Main Results:

• Both autologous cartilage and allogeneic implant techniques achieve good aesthetic and functional results.
• Autologous reconstruction, while requiring specialized skill, presents a lower risk of post-operative exposure.
• Successful ear reconstruction positively influences patients' social integration and daily life quality.

Conclusions:

• Auricular reconstruction is an optional but beneficial procedure for patients with microtia.
• Both autologous and allogeneic implant methods are viable, with distinct risk profiles.
• The choice of technique should consider surgical expertise, patient factors, and desired outcomes for improved psychosocial functioning.
