Inferior alveolar nerve paralysis is a rare complication of third molar extraction, occurring in 0.6% of patients. The risk increases with patient age and complex surgical procedures like bone removal.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Neurology
  • Dental Anesthesia

Context:

  • Surgical removal of impacted third molars is a common dental procedure.
  • Nerve injury, particularly to the inferior alveolar nerve (IAN), is a known complication.
  • Understanding the incidence and risk factors for IAN paralysis is crucial for patient counseling and surgical planning.

Purpose:

  • To determine the incidence of inferior alveolar nerve paralysis following surgical extraction of impacted third molars.
  • To identify patient demographics and surgical factors associated with an increased risk of IAN paralysis.

Summary:

  • A study of 789 patients undergoing 1,299 third molar extractions found an 0.6% incidence of inferior alveolar nerve paralysis.
  • The incidence was higher in patients over 40 years old (3.5%) compared to younger age groups.

Related Experiment Videos

  • Procedures requiring root splitting or bone removal were associated with a greater risk of nerve injury.

    • Impact:

    • Provides essential data on the incidence of inferior alveolar nerve paralysis in a large patient cohort.
    • Highlights age and surgical complexity as significant risk factors for nerve injury.
    • Informs surgical decision-making and patient consent processes in third molar surgery.
