Summary
This study compared three total ear reconstruction methods. Skin expansion with autogenous rib cartilage or Medpor framework, and ear prosthesis all yielded good cosmetic results when matched to patient suitability.
Area of Science:
- Reconstructive surgery
- Plastic surgery
- Biomaterials in medicine
Background:
- Total ear defects can result from trauma, infection, or congenital conditions.
- Reconstruction aims to restore both form and function.
- Various techniques exist, each with specific indications and outcomes.
Purpose of the Study:
- To evaluate the indications and outcomes of three distinct total ear reconstruction methods.
- To compare the efficacy of skin expansion with autogenous rib cartilage framework, Medpor framework, and ear prosthesis.
Main Methods:
- A retrospective analysis of 960 cases of total ear defect.
- Treatment modalities included skin expansion with autogenous rib cartilage framework (n=786), skin expansion with Medpor framework (n=150), and ear prosthesis (n=24).
- Indications and results for each method were systematically analyzed.
Main Results:
- All three methods achieved satisfactory cosmetic outcomes.
- Autogenous rib cartilage framework is ideal for patients under 30 with healthy mastoid skin.
- Medpor framework suits adults over 30 or those with mild mastoid infections.
- Ear prosthesis is recommended for severe skin damage or patients avoiding surgery.
Conclusions:
- Appropriate patient selection is crucial for successful total ear reconstruction.
- Each method offers a viable solution depending on individual patient factors and defect characteristics.
- Satisfactory aesthetic results are achievable across all evaluated techniques.
