Abstract: This paper reviews the clinical applications of MEG in patients with sensory disturbances of the lip and tongue due to unilateral injury of the mandibular nerve. Multiple non-invasive approaches are available for the evaluation of human brain function. Some of these approaches are electroencephalography (EEG), magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET). MEG is particularly advantageous due to its high spatiotemporal resolution. Mandibular nerve injury during orofacial surgery may result in sensory deficits of the lower lip and tongue, which often lead to speech disorders, eating difficulties, and significant reductions in patients quality of life. Conventional methods for evaluating abnormalities in lip and tongue sensation in clinical settings include the von Frey and two-point discrimination tests. However, the reproducibility and reliability of such tests remains low due to the subjective nature of the information provided by the patient. In this paper we propose that MEG can be used to effectively and objectively detect sensory abnormalities of the lower lip and tongue.
