Etiology of Lingual Nerve Injuries in the Third Molar Region

It does appear that different modalities in nerve injury produce a different type of injury both clinically and histologically. Clinical recovery may occur best with close approximation of a sharp scalpel-type wound or excision of a crushed area of nerve with reapproximation of the nerve endings, but a ragged wound caused by a fissure bur may require excision back to healthy nerve with subsequent reapproximation, whereas with the stretching injury it may be difficult to ascertain the edges and limits of the wound, and difficult to repair, and it may be most appropriate to rely on a natural healing process for the best results.
