Introduction: Coronectomy is a treatment method for mandibular third molars in close proximity with the alveolar inferior nerve, preventing nerve injuries. In this study, a rare case of a delayed lip paresthesia two years post-coronectomy of a mandibular third molar will be presented with accompanying literature review.
Case: A 41-year-old female initially presented with a symptomatic right mandibular third molar. Panoramic Xray evaluation showed a high risk for inferior alveolar nerve (IAN) injury. As such, further analysis using a CBCT scan demonstrated the IAN to be coursing through the roots, which were united at their apical portions. Based on these findings, coronectomy was performed instead of surgical extraction.
Following an uneventful recovery, the patient remained asymptomatic for two years until she presented with paresthesia on the right lower lip. Subsequent 2-year follow-up CBCT imaging revealed eruption of the roots vertically, causing a tension and associated paresthesia of the IAN. As such, a secondary operation was carried out splitting and retrieving the roots separately using burs and chisels, preserving the IAN. Paresthesia resolved within the first post-operative month, and the patient remained symptom-free on the first-year follow-up.
Conclusion: This atypical case draws attention to the need for long-term follow-up after coronectomy procedures and outlines a favorable surgical approach to manage delayed complications such as paresthesia.
