Анатомо-топографическое и рентгенологическое обоснование дополнительного пути иннервации фронтальных зубов нижней челюсти

Авторами статьи проведена анатомическая диссекция язычных каналов нижней челюсти. Выявлены три группы язычных каналов. Для изучения структур сосудисто-нервных пучков использовалось эндоскопическое оборудование. Дополнительное гистологическое исследование проводилось при малом размере сосудисто-нервного пучка. По результатам исследования было выявлено, что верхние альвеолярные язычные каналы содержат нервные структуры. Срединный и нижние каналы содержат преимущественно сосуды системы язычной и лицевой артерий. Авторы предполагают, что дополнительная иннервация резцов нижней челюсти осуществляется за счет ответвлений язычного нерва. Не выявлено взаимосвязи между челюстно-подъязычным нервом и язычными каналами нижней челюсти.

The authors of the articles have carried anatomy dissection study of lingual mandibular canals. It was identified three groups lingual channels. The structures of neurovascular bundles were exanimate with endoscopic equipment. In case of small neurovascular bundle size, additional histological investigation studies were carried out. By the results of the study, it was found, that the upper alveolar lingual channels contain neural structures. The middle and lower channels contain primarily vessels of the lingual and facial arteries. The authors suggests, that additional innervation of the lower jaw incisors is carried through branches of lingual nerve. There were no relationship between myelohyoid nerve and lingual mandible canals.
