Bell's palsy and dental procedures: A cross-sectional study

Facial nerve palsy, including Bell's palsy, can occur as a post-dental complication, leading to sudden facial muscle weakness or paralysis. This study reviewed 2543 subjects with idiopathic facial palsy over 10 years, identifying 18 cases (0.70%) of facial paralysis post-dental treatment. All cases involved ipsilateral paralysis, with a mean onset of 3.82 days after treatment. Early diagnosis and management significantly improve prognosis, highlighting the importance of preventive measures and awareness. The identification of facial paralysis as a rare post-dental complication and the finding that early diagnosis and management significantly improve the prognosis of the condition.
