Management of Facial Paralysis Following Skull Base Surgery: A Comprehensive Narrative Review

Objectives: Facial paralysis is a devastating yet frequent complication of skull base surgery, significantly impacting quality of life through functional impairments and psychosocial consequences. Management is complex and requires an individualized approach based on duration of paralysis, etiology and extent of nerve injury, overall prognosis, and rehabilitative goals. This review provides a comprehensive overview of current strategies for managing post-skull base surgery facial paralysis. Methods: A narrative review of the literature was performed, analyzing surgical reanimation techniques (nerve grafting, nerve transfers, regional and free muscle transfers), static procedures for facial symmetry and ocular protection, and non-surgical interventions such as physical therapy, botulinum toxin injections, and psychological support. Key criteria guiding treatment selection, including muscle viability and timing since injury, were examined. Results: Dynamic surgical approaches remain central to restoring movement. Nerve grafting and transfers are effective when viable musculature is present, whereas regional or free muscle transfers are required in long-standing paralysis with irreversible atrophy. Static procedures provide adjunctive improvements in resting symmetry and eye protection. Non-surgical strategies, including rehabilitation therapy and botulinum toxin, enhance functional outcomes and reduce synkinesis. Psychological counseling addresses the profound emotional burden associated with facial disfigurement. Across modalities, individualized treatment planning is crucial. Conclusions: Management of facial paralysis after skull base surgery demands a multidisciplinary, patient-centered approach. Combining surgical and non-surgical interventions optimizes functional and aesthetic outcomes, helping restore both facial movement and psychosocial well-being.
