Abstract

Purpose

Mandibular third molar extractions are common treatment in oral maxillofacial surgery, but risk disturbance of the lingual nerves causing anesthesia, eating difficulty and allodynia, which can seriously reduce patient quality of life. This study investigates the change in allodynia before and after repair in patients with lingual nerve disorder.

Subjects and methods

This retrospective cohort study comprises the 52 patients with affected lingual nerve after third molar extraction at our hospital over a 7-year period. Pre- and postoperative (6 months and 12 months) neurosensory records were analyzed.

Results

Fifty-two patients underwent lingual nerve repair and returned for at least 1 year of follow-up. Mean age was 36.8 ± 11.9. Median interval between injury and surgery was 5 (4, 8) months. In 92.9% of those with pain before surgery, allodynia disappeared postoperatively.

Conclusions

This study shows that microsurgical lingual reconstructions are effective in patients with preoperative allodynia, but a small number of patients may have remaining allodynia after surgery. Large-scale, more detailed analysis of such cases is required.
