[Template design of tissue flaps for covering auricular cage in one-stage total auricular reconstruction].

ABSTRACT

OBJECTIVE: To study the template design of tissue flaps for covering auricular cage in order to acquire accurate and reliable design method. METHODS: By the theory of engineering drawing and three-dimensional measuring on CT image, three dimensional configuration of 40 auricular surfaces were expanded approximately, and the character of them was analysed for the template design. RESULTS: It is similar of the expanded graphs of auricular surface three dimensional configuration in healthy persons, and simplified template of tissue flaps is drawn based on the key points of the above graph. CONCLUSIONS: CT three-dimensional measurement of auricular surface configuration can be used to design the template of tissue flaps for covering auricular cage, and can provide accurate and reliable template of tissue flaps for clinics.
