Answer

Most patients with Bell palsy recover without any cosmetically obvious deformities. Approximately 30% of patients, however, experience long-term symptoms following the paralysis, and approximately 5% are left with an unacceptably high degree of sequelae. Bell palsy sequelae include incomplete motor regeneration, incomplete sensory regeneration, and aberrant reinnervation of the facial nerve.
