Task: Intent Identification
Input (English): Skin grafting is needed for traditional auricular reconstruction. As the skin grafts contract, the postoperative framework is distorted. This leads to a decrease in the auriculocephalic angle. The objective of this study was to test a new method to cover the reconstructive framework by using three skin flaps and a larger tissue expander than that normally used. This may reduce the distortion of the reconstructed ear and create a well-shaped auriculocephalic angle.', 'A large expander was inserted in the postauricular mastoid area. Three expanded flaps were then created to cover the anterior and posterior frameworks, with separate mastoid coverage. By measuring the height and angle at three different points on the reconstructed ear and comparing them with the contralateral normal ear, a system for measuring the auriculocephalic angle was established.', "The surface of the framework and the mastoid area were covered by three flaps developed from one large tissue expander. The appearance of the reconstructed ears was similar to that of the normal side by the patient's 6- to 12-month follow-up. The difference in the distance at the three points between the reconstructed and normal sides after the three-flap reconstruction was less than that following traditional reconstruction (p\xa0<\xa00.05). The variation in the angle measured at these three points in the three-flap group was also much smaller than that in the traditional group (p\xa0<\xa00.01).
