[Application on the clinical effect of immediate repair of part helix defect with flap on post aurem and mastoid region].

Objective

To investigate the clinical effect of the flap on post aurem and mastoid region on immediate repair of part helix defect. Method: Fifteen patients with part helix defect were immediately repaired using the flap on post aurem and mastoid region. Firstly, the skin tissue above the defect of the helix was used as the pedicle. The flap was drawn toward the post aurem and mastoid region closing to the auriculocephalic angle. The flap was generally 3-4 cm long and at least 1 cm wide. Secondly, the flap was lifted on the perichondrium, and the structure of the helix was formed by upward rotation of the flap to repair the defect of the helix. Finally, the flap was sutured to repair the helix defect. Result: Fifteen cases were applied with this method to repair immediately the defect in the emergency environment. The sizes of helix contour were satisfactory and the auriculocephalic angles had not changed. The ear shape was stable after 1 to 3 months of followup.

Conclusion

The flap on post aurem and mastoid region could immediately repair the part helix defect. It has the advantages of simple operation, high flap survival rate and one-time satisfactory shape..
