INTRODUCTION
Facial nerve palsy (FP) has multiple etiologies and is estimated to affect 20-30 per 100,000 individuals in the United States annually. Approximately 30% of affected patients experience long-term sequelae that do not fully resolve.¹,² These sequelae--both functional and aesthetic--can significantly impact quality of life and lead to psychosocial distress.3,4
In addition to visible asymmetry, FP may result in taste disturbances, dry eye syndrome, gustatory lacrimation, and motor deficits affecting speech and mastication. Botulinum toxin (BTX) has played an instrumental role in the advancement of multimodal management strategies for facial nerve disorders. Understanding facial nerve anatomy, pathophysiology, and postparalytic sequelae is essential prior to addressing aesthetic asymmetry or functional deficits.5 This review proposes a neuroaesthetic framework in which facial paralysis is first evaluated through etiology and functional deficits, followed by targeted neuromodulator interventions that address therapeutic symptoms and aesthetic asymmetry concurrently.
A Neuroaesthetic Framework for Facial Paralysis
Framework Overview
Facial paralysis represents a complex interaction between neurologic injury, functional impairment, compensatory motor activity, and aesthetic asymmetry. Management strategies that focus solely on visible asymmetry may overlook underlying neuromuscular and autonomic sequelae that contribute to persistent symptoms and patient distress.1-4 A neuroaesthetic framework integrates neurologic understanding with aesthetic principles to guide comprehensive and safe management of facial paralysis.
