Trigeminal nerve injuries

Injuries to peripheral branches of the trigeminal nerve are relatively uncommon; however, they are fairly debilitating to the patient when they do occur. Treating clinicians should evaluate and document baseline neurosensory testing results on patients and perform serial examinations approximately every two weeks. If there are no changes after one month, consideration should be given for referral to an oral and maxillofacial surgeon trained in trigeminal nerve microsurgery. Many patients will go on to spontaneous recovery; however, a number will require microsurgery. It is prudent for the treating clinician to recognize, document and discuss the injury with the patient prior to referring to the oral and maxillofacial surgeon trained in microsurgery.
