“…According to the literature, the ELN is a linear nerve trunk (Olthoff et al 2007;Oliveira and Silva 2007). Based on a study of 60 adult cadavers, Sun and Chang (1991) reported that the superior laryngeal nerve (SLN) and its branches often connected with one or more branches from the cervical sympathetic chain (CSC) to form an SLN loop.…”

This study was conducted to investigate the topographic relationship between the external laryngeal nerve (ELN) loop and the superior thyroid artery (STA), in order to provide the anatomical foundations for protecting the ELN during surgery. In the present study, 48 adult human cadavers were dissected and analyzed. For the 21 (21.9%) low-position ELN loops observed, the neurovascular relationship between the STA and the nerve was classified into four types: (1) the artery overlapped the nerve; (2) the artery passed through the ELN loop; (3) the muscular branch of the ELN loop and the laryngeal branch of the STA coursed together; and (4) the branches of the STA and the ELN loop were interlaced. Our study suggested that the patterns of ELN loops are so complicated that they have not been statistically defined in any previous study, which should be kept in mind when attempting to protect the nerve from injury. Also, because of the variable morphology of the ELN loop and its complicated topographic relationship to the STA, the vessels should be individually isolated and then ligated during thyroidectomy. When ligating the laryngeal branch of the STA during larynx surgery, special attention should be paid to avoiding damage to the muscular branch of the ELN/ELN loop.

“…Because of the contiguity with the superior thyroid artery, iatrogenic lesions of the ESLN in thyroidectomies are mentioned in the literature [9][10][11][12] . It is reasonable to assume that iatrogenic injuries, which may involve the superior parathyroid glands, are influenced by anatomical variations of the nerve in relation to the short vertical segment of the superior thyroid artery before it penetrates the gland, since the superior thyroid vein usually lies more laterally in relation to the cranial border of the thyroid lobe; thus, farther from the nerve [13][14][15][16][17] .…”

OBJETIVO: Construir um protocolo das relações anatômicas topográficas do ramo externo do nervo laríngeo superior (NLSE) com a artéria tireóidea superior, para minimizar as falhas das propostas descritas na literatura. MÉTODOS: Foram dissecadas bilateralmente as regiões cervicais de 57 cadáveres frescos, no Instituto Médico-Legal do Estado do Amazonas, com identificação fotográfica dos NLSE e respectivas relações com a artéria tireóidea superior. A partir dos dados obtidos elaborou-se classificação: Tipo1: NLSE não identificado; Tipo 2: NLSE cruza a artéria tireóidea superior a distância maior de 1,5cm do limite cranial do lobo da glândula tireóide; Tipo 3: NLSE cruza a artéria entre 1cm e 1,5cm do limite cranial do lobo da glândula tireóide; Tipo 4: NLSE cruza a artéria a menos de 1cm do limite cranial do lobo da glândula; Tipo 5: NLSE cruza, látero-medialmente, abaixo do limite cranial do lobo tireóideo. Como suplemento classificatório, os tipos 2, 3 e 4 receberam subclassificação: A - quando se encontrava parcial ou totalmente envolto no tecido conjuntivo superficial peri-muscular ou intra-muscular, no constritor inferior da faringe, em mais da metade de seu percurso, após cruzar a artéria tireóide superior; B - quando se encontrava fora destes tecidos. RESULTADOS: Tipo 1, 11,88%; Tipo 2, 13,86%; Tipo 3, 34,65%; Tipo 4, 38,61% e Tipo 5, 0,99%. CONCLUSÃO: Os NLSE mais próximos ao limite cranial (Tipos 3 e 4) percorriam, em sua maioria, o tecido frouxo peri-muscular ou intramuscular, no pólo superior da tireóide, o que neste estudo, desobrigam identificação sistemática do nervo nas tireoidectomias (p=0,075).
