Summary

Surgical removal of impacted lower third molars can cause lingual dysesthesia. Deeper impactions and specific surgical techniques significantly increase risk, but prompt intervention with incomplete sensory loss aids recovery.

Area of Science:

  • Oral Surgery
  • Dental Anesthesia
  • Neurology

Background:

  • Lingual dysesthesia is a potential complication following lower third molar extraction.
  • Understanding causative factors is crucial for risk mitigation and patient counseling.

Purpose of the Study:

  • To investigate surgical, operator, and anatomical variables influencing lingual dysesthesia post-third molar surgery.
  • To assess the predictive value of sensory loss area on recovery.

Main Methods:

  • Prospective study of 602 patients undergoing 1040 lower third molar extractions.
  • Analysis of 22 potential causative factors using Chi-squared and logit analysis.
  • Evaluation of lingual dysesthesia incidence, duration, and recovery patterns.

Main Results:

  • Overall incidence of lingual dysesthesia was 11.5% (120 cases).
  • Significant risk factors included deep impaction, bone removal, lingual flap elevation, and longer operating times.
  • Operator experience did not significantly affect incidence.

Conclusions:

  • Specific surgical factors, not operator skill, are key predictors of lingual dysesthesia.
  • Incomplete sensory loss area within 6 months predicts full recovery, aiding prognosis.
