ABSTRACT
OBJECTIVE To study clinical application technique of skin soft tissue expansion in auricular reconstruction.METHODS 502 patients (517 ears)were selected for skin soft tissue expansion. Skin expander was implanted and liquid injected routinely to expand skin to obtain excessive skin for auricular reconstruction.RESULTS Of 502 patients (517 ears),10 patients(10 ears) had complicated skin hematoma formation which had been cleaned out successfully;12 patients(12 ears) had complicated skin expander uncover,skin expander was taken out and reposted 4 months later in 7 patients(7 ears) without affecting opertative effect;No infection was found and all patients obtain satisfactory effect. CONCLUSION Skillful and normative operation is the key for preventing complication.Fibre layer must be got rid of during operation.Skin expander auricular reconstruction has the advantage of obvious concave and protruding figure as well as satisfactory cubical sense.It is the perfect method for treating ear malformation at present.
