Auricular Protection after Ear Reconstruction Using an Antipressure Alarm

Auricular protection is an important part of postoperative care for ear reconstruction and has an important impact on the expected outcome of the surgery. Therefore, we developed an antipressure alarm to protect the reconstructed ear in the supine position. The device consists of three components: an alarm, a pressure detector, and an adjustable elastic band. When the patient is in a supine position, the pressure sensor is located above the back of the reconstructed ear. When the head is rotated to the affected side, the pressure detector senses the pressure signal in advance compared with the reconstructed ear, and then triggers an alarm to remind the patient to adjust his position in time to avoid pressing the reconstructed ear. The device has been applied to more than 100 patients and has achieved satisfactory clinical results.
