Facial Paralysis (FP) profoundly impairs the life of individuals, both functionally and psychosocially. Surgical approaches to treat this condition are myriad, but the ultimate goal is to restore symmetry and movement. Ablative surgery for tumors of the head and neck region are amongst the most common etiologies causing FP and this group of patients represents unique challenges. Surgical defects may have multiple competing reconstructive requirements and addressing the FP must be considered in this context. Furthermore, extent of disease, patient age, duration of preceding paralysis, adjuvant treatment, as well as the various different type of facial nerve defects are factors that may influence the type of reconstructive technique selected to address the FP.The complexity of FP especially following head and neck ablation can lead to results that are inconsistent and humbling. FP defects can be broadly described as having the potential for facial muscle recovery versus irreversible paralysis. Literature that specifically focuses on primary facial reanimation procedures in the oncological setting is scarce. We present a comprehensive review of primary facial reanimation after ablative surgery including the descriptions of a wide array of surgical techniques such as reinnervation, dynamic muscle transposition, static suspension, and free tissue transfer. Understanding the advantages and limitations of the different options will enable the surgeon to offer treatment for the paralyzed face for most clinical scenarios.
