An unusual communication between the trunk of the mandibular nerve and the lingual nerve in a female cadaver

AbstractMandibular nerve is a branch of Trigeminal nerve which gives off Lingual, Inferior alveolar, Auriculotemporal, Buccal branch and motor branches to muscles of mastication. Anatomical variations related to mandibular nerve and its branches are of great importance to Oral maxillofacial surgeons and Dentists. During routine cadaveric dissection of infratemporal fossa of an adult male in the Institute of Anatomy, Madurai Medical College, variations in the branching pattern of mandibular nerve and an unusual course of lingual nerve were found on the left side. Such anatomical variations of mandibular nerve and its branches are of clinical significance during dental procedures and maxillofacial surgeries.

The lingual nerve is a branch of the posterior trunk of the mandibular nerve. It provides sensation and taste to the ipsilateral anterior two-thirds of the tongue. Posttraumatic neuropathy of the lingual nerve can be chronic and debilitating long after the inciting trauma. In this operative video, the authors describe a novel technique for the treatment of lingual nerve neuropathy with neuromodulation. They present a case of a 69-year-old female with posttraumatic lingual nerve neuropathy after left molar extraction. The patient reported 95% symptom improvement after the procedure. This video demonstrates the feasibility of lingual nerve neuromodulation.The video can be found here: https://youtu.be/l-CKP8-8eqk

Clinical Determination

Abstract Purpose Recently we described mapping of the lingual nerve clinically in patients using electrical nerve stimulation. This paper reports results of a larger study with inter- and intra-observer reliability and comparison with positional measurements from magnetic resonance imaging (MRI). Methods In 50 healthy participants, measurements were taken when subjects felt a tingling sensation in the tongue induced by a stimulation probe over the lingual nerve. Three positions were measured in relation to the third molar. Measurement reliability was tested for both inter-observer and intra-observer agreement and positional data of the lingual nerve measured clinically was also compared with nerve position as measured from MRI scans. Results Out of 50 participants, 96 nerves (49 = left/47 = right) were included in the study. The lingual nerve was identified in 90% (87) of this sample. The mean of height of the nerve in points A, B and C were 9.64 mm, 10.77 mm and 12.34 respectively. Inter-and intra-observer agreement was considered to be good to excellent (ICC = 0.8–0.96). Agreement between nerve mapping measured values and MRI measured values was good (ICC < 0.6). Conclusion This technique may prove useful for the clinical determination of lingual nerve position prior to procedures in the third molar region.
