Auricular cartilage is widely used in rhinoplasty because of its excellent elasticity, curvature, and plasticity; however, changes in auricular morphology at the donor site remain a key concern affecting patient satisfaction and safety. This review focuses on the postoperative morphological stability of the donor-site auricle by synthesizing recent reviews and original studies, and it summarizes influencing factors, assessment methods, and clinical strategies. Evidence indicates that morphological stability is closely related to the anatomical and biomechanical foundations of the auricle, the amount and location of cartilage harvest, reconstruction methods and suturing strategies, and objective measurements with long-term follow-up. However, standardized assessments and long-term evidence remain insufficient, highlighting the need for surgical technique optimization and individualized strategies in future practice.
