Microsurgical Reconstruction of the Ear and Temporal Region: Structural and Functional Considerations Including Hearing Rehabilitation—A Narrative Review

Reconstruction of the ear and temporal region presents unique challenges due to the complex anatomy of the lateral skull base and the need to restore both structural integrity and auditory function. Historically managed as separate entities, auricular reconstruction and hearing rehabilitation are increasingly approached in an integrated manner, supported by advances in microsurgical techniques and implantable hearing technologies. This narrative review synthesizes contemporary evidence on microsurgical reconstruction of the ear and temporal region in conjunction with hearing rehabilitation, analyzing a wide range of existing surgical techniques in an integrative manner. Reconstructive techniques discussed include local and regional flaps, free tissue transfer, auricular framework reconstruction using autologous cartilage or alloplastic materials, external auditory canal reconstruction, and subtotal petrosectomy. Hearing rehabilitation options reviewed encompass bone-anchored hearing systems, active and passive transcutaneous devices, middle ear implants, and cochlear implantation. Simultaneous reconstruction and implantation may reduce surgical burden and enable earlier hearing restoration in carefully selected patients, while staged approaches remain advantageous in complex or high-risk scenarios, particularly in the presence of chronic infection or extensive temporal bone surgery. Multidisciplinary collaboration, meticulous preoperative planning, and long-term follow-up are essential to optimize outcomes.
