Research Article: Accuracy of MR neurography as a diagnostic tool in detecting injuries to the lingual and inferior alveolar nerve in patients with iatrogenic post-traumatic trigeminal neuropathy

Date Published: 2023-12-04

Abstract:
MR neurography has the ability to detect and depict peripheral nerve injuries. This study evaluated the potential of MR neurography in the diagnosis of post-traumatic trigeminal neuropathy.

Introduction:
The trigeminal nerve (TN) provides sensation to the face via its three major branches: the ophthalmic, maxillary, and mandibular nerves. The latter has an additional function in supplying innervation to the muscles responsible for biting and chewing. Maxillofacial surgery and dental procedures (e.g., implant placement, molar tooth extraction, local anesthesia) have a risk of damage to one of these branches, which can result in the development of neurosensory deficiencies [1,2,3], a condition called iatrogenic…
