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

Area of Science:

• Neurology
• Dentistry
• Ophthalmology

Background:

• Facial nerve palsy, including Bell's palsy, is a known neurological condition.
• Dental procedures can rarely lead to complications affecting facial nerve function.
• Understanding the link between dental treatment and facial palsy is important for patient care.

Purpose of the Study:

• To investigate the incidence and characteristics of facial nerve palsy following dental treatment.
• To determine the time of onset and affected side of facial paralysis post-dental procedures.
• To emphasize the significance of early diagnosis and management for improving prognosis.

Main Methods:

• Retrospective review of 2543 subjects diagnosed with idiopathic facial palsy over a 10-year period.
• Identification of cases with a history of recent dental treatment.
• Analysis of clinical presentation, onset, and management outcomes.

Main Results:

• Eighteen cases (0.70%) of facial paralysis were identified as a post-dental complication.
• All identified cases presented with ipsilateral facial paralysis.
• The mean onset of paralysis was 3.82 days after dental treatment.

Conclusions:

• Facial nerve palsy is a rare but recognized complication of dental treatment.
• Prompt diagnosis and intervention significantly enhance the prognosis for patients experiencing post-dental facial paralysis.
• Increased awareness among dental professionals and patients is vital for preventive measures and timely management.
