“…Niemi et al [33] affirmed that the deterioration of the function of the LN becomes more difficult with tongue control in anterior-posterior movements. This involvement in the voice production might be the result of the motor impairment, suggesting that the damage also results in interference in the proprioceptive answer of the muscular fibres of the tongue.…”

ObjectivesThis study evaluated the relationship of the lingual nerve with the adjacent anatomical structures of the mandibular third molar region, influencing the dentist to be aware of the variability of these relationships.Material and MethodsSamples of 24 human corpse half-heads were selected and divided according with the presence or absence of the mandibular third molars. The lingual nerve (LN) was explored, showing its run from the oblique line until its crossing with the submandibular gland duct. The measurements along the LN and the adjacent anatomical structures were taken at the retromolar, molar and sublingual region with the use of a digital caliper.ResultsThe distance from the LN and the third molar socket, which represents the horizontal distance of the lingual plate to the nerve, on average, was 4.4 mm (SD 2.4 mm). The distance from the LN and the lingual alveolar rim, which represents the vertical relationship between the nerve and the lingual alveolar rim of the third molar socket, on average, was 16.8 mm (SD 5.7 mm). The LN has a varied topography that leaves it very vulnerable during any procedure executed in this region.ConclusionsUnless adequate protection of the lingual nerve is acquired by following an adequate surgical technique, the lingual nerve will always be vulnerable to damage during surgical intervention or manipulation in this region.

“…In a previous study with vowel sounds, a man with a permanent lingual nerve lesion had more prominent changes than men whose lingual nerve function was temporarily disturbed by local anesthesia 11 . The patient's formant changes were found mainly in F1.…”

“…Earlier studies, in which lingual nerve function was temporarily disturbed by local anesthesia, have shown that sensory dysfunction of the tongue affects vowels, diphthongs and sibilant sound /s/ production [11][12][13] . The effects are extremely individual and variable.…”

“…In these kinds of situations, speakers need to modify their normal articulatory configurations in order to produce acoustically acceptable speech sounds. Earlier, the authors of this study reported that alterations in acoustic characteristics of speech sounds are observed in connection with a reduction in tactile and proprioceptive feedback mechanisms 8,9 .…”
