Establishing the topographic features of the nerves of the larynx is an important area of modern medicine due to the frequent surgical intervention on the organs of the neck. It is known that the innervation of the larynx is provided by the superior and recurrent (inferior) laryngeal nerves. The laryngeal nerves, as well as their branches, can form many anastomoses between themselves inside the organ, which should be taken into account by practicing surgeons to prevent the development of postoperative complications. So, there are a large number of different variants for the innervation of the muscles and mucous membrane of the larynx due to the presence of intralaryngeal anastomoses. As for extralaryngeal anastomoses, they are rare and are of great interest to both morphologists and practicing surgeons. During surgical intervention on the thyroid gland during intraoperative identification of the superior and recurrent laryngeal nerves, the presence of extralaryngeal anastomoses between them can make it difficult to identify the nerves and lead to iatrogenic damage to the latter.This article describes 3 cases of extralaryngeal anastomoses between the nerves of the larynx established during the macroscopic preparation of organocomplexes of the neck of an adult. The 1st case is an anastomosis between the internal and external branches of the superior laryngeal nerve, the 2nd and 3rd are anastomoses between the external branch of the superior laryngeal nerve and the recurrent laryngeal nerve.
