Background:
The creation of a high-defining tragus and antitragus complex remains a demanding challenge during staged lobule-type microtia reconstruction. The success of the complex carving relies greatly on proper operation of the cartilage, which is commonly residual cartilage of various sizes. The authors discuss the relevant details for sculpting the tragus and antitragus complex based on cartilage remnants in various conditions.
Methods:
A series of 562 lobule-type microtia patients underwent autogenous costal cartilage auricular reconstruction between 2007 and 2016. Because of the various sizes and shapes of the remnant cartilage used for the tragus and antitragus complex reconstruction, the authors have described possible scenarios for fabrication and introduced relevant tactics for appropriate treatment.
Results:
Corresponding methods for various scenarios in tragus and antitragus complex fabrication have been shown to demonstrate a satisfactory appearance. The results demonstrate the achievement of a harmonious tragus and antitragus complex for the integrity of a constructed ear.
Conclusions:
Proper use of the residual cartilage for tragus and antitragus complex sculpture plays a vital role in acquiring a favorable contour of the auricle in microtia reconstruction. The introduced approach enhances the aesthetics and functionality of the complex for modern life.
Clinical Question/Level Of Evidence:
