Abstract(s)
O nervo lingual é um dos mais importantes nervos da cavidade oral, é ele quem providencia sensação geral à mucosa dos dois terços anteriores da língua, mucosa sublingual do pavimento da boca e da gengiva língual e a ele junta-se o nervo da corda do tímpano que providencia sensação de paladar. O nervo lingual encontra-se entre 2,28 a 16,8 mm abaixo da crista alveolar e 0,57 a 7,10mm mesialmente à tábua óssea lingual. Devido a sua localização anatómica variável torna-se difícil a realização de atos clínicos na zona circundante, zona esta que está sujeita com muita frequência a intervenções cirúrgicas. Sendo as principais causas de lesão as técnicas anestésicas, reabilitações e cirurgias. As diversas causas de lesão têm vindo a ser estudadas de forma a diminuir a probabilidade da sua ocorrência, principalmente no caso da extracção de terceiros molares mandibulares que é o ato cirúrgico que pode apresentar maior risco para o nervo lingual.
The lingual nerve is one of the most important of the oral cavity, it is the one that provides general sensation to the mucosa of the anterior two thirds of the tongue, the sublingual mucosa, the floor of the mouth and the lingual gum, it carries the nerve of the tympanic cord that provides taste sensation. The lingual nerve lies between 2.28 to 16.8 mm below the alveolar crest and 0.57 to 7.10 mm mesially to the lingual plate. Due to its variable anatomical location it is difficult to perform clinical acts in the surrounding area, which is very often subject to surgical intervention. Being the main causes of injury anesthetic techniques, rehabilitation and surgery. The various causes of injury have been studied in order to decrease the likelihood of injury, especially in the case of extraction of mandibular third molars, which is the surgical act that presents the greatest risk to the lingual nerve.
