Strategies of Total Auricular Reconstruction for Patients With Poor Skin Coverage at the Mastoid Area.

Objective: Burns and injuries can lead to massive defects in the mastoid tissues, which increase the difficulty of ear reconstruction. It is crucial to choose an appropriate surgical method for these patients. Here, we introduce strategies for auricular reconstruction in patients without satisfactory mastoid tissues.

Methods: From April 2020 to July 2021, 12 men and 4 women were admitted to our institution. Twelve patients were severely burned, 3 patients experienced car accidents, and 1 patient had a tumor on his ear. The temporoparietal fascia was used for ear reconstruction in 10 cases, and the upper arm flap was used in 6 cases. All of the ear frameworks were made of costal cartilage.

Results: The location, size, and shape of both sides of the auricles were generally the same. Two patients needed further surgical repair because of cartilage exposure at the helix. All of the patients were satisfied with the outcome of the reconstructed ear.

Conclusion: For patients with ear deformity and poor skin coverage in the mastoid area, we can choose the temporoparietal fascia if the patient's available superficial temporal artery is longer than 10 cm. If not, we can choose the upper arm flap. The latter needs a five-stage operation, which is more time consuming and difficult than the former. Moreover, the expanded upper arm flap is thinner and has better elasticity than the temporoparietal fascia, so the shape of the reconstructed ear is better. We need to evaluate the condition of the affected tissue and choose the appropriate surgical method to achieve a good result.
