Facial nerve palsy, a rare dental complication, can cause sudden facial paralysis. Early diagnosis and management are crucial for improving patient outcomes and prognosis after dental procedures.

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.
