Non-recurrent nerve from the vagus anterio-medially located in the carotid sheath

Öz:

Vagus sinirinden çıkan non-reküren larenjeal sinir nadir bir anatomik varyasyondur. Vagus, boyun nörovasküler kılıf içinde, karotis arter ve internal jügüler ven arasında ve arkasında aşağıya doğru dikey seyreder. Vagusun da bazı anatomik varyasyonlarına rastlanır. Bu yazıda hem vagus siniri, hem de inferior larenjeal sinirde (ILS) eş zamanlı görülen iki anatomik varyasyon olgusu sunulmaktadır. Total tiroidektomi yapılan bir olguda her iki ILS bulunmuş, servikal seyir boyunca tam olarak ortaya konmuş ve korunmuştur. Sağ tarafta ILS'in vagustan çıktıktan sonra inferior tiroit artere paralel kısa bir seyirle normal yerinden larenkse giren non-reküren sinir bulundu. Diseksiyonu sonrası tiroit sağ lobu mediale çekilince ortaya konan vagus sinirinin karotis arterin medialinde seyrettiği tespit edildi. Aynı olguda, medial seyirli vagustan çıkan non-reküren sinir birlikteliği gözlendi. Non-reküren sinir ve servikal nörovasküler kılıf içinde medial yerleşimli vagus siniri iki farklı varyasyondur. Bu iki varyasyona aynı olguda rastlanması ilgi çekici bir özelliktir. Emniyetli tiroit cerrahisi, ILS'in bulunması, tam ve doğru olarak ortaya konmasına dayanır. Varyasyonları da içerecek şekilde komşu sinir yapıların anatomisinin tam olarak bilinmesi komplikasyonsuz tiroit cerrahisi için gereklidir.

Karotis kılıfı içinde ön-medialde yerleşik vagustan çıkan non-reküren sinir

Öz:

Non-recurrent inferior laryngeal nerve (ILN) arising from the vagus nerve is a rare anatomic variation. The vagus descends vertically in the cervical neurovascular bundle, between and posterior to common carotid artery (CCA) and internal jugular vein (IJV). The vagus has also some anatomic variations. We present a case of two coincident anatomic variations both ILN and the vagus nerve. A patient with multinodular goiter was surgically treated with total thyroidectomy. Both two ILNs were identified, fully exposed and preserved along their cervical courses. We found that the right non-recurrent ILN directly arises from cervical vagal trunk, and enters the larynx at usual point after a short transverse course parallel to the inferior thyroid artery. The vagus nerve, easily exposed after dissection of the right lobe of the thyroid gland, is located medially to the CCA. We discovered the association of non-recurrent ILN and medially located vagus nerve in the same patient. Non-recurrent nerve and medially located vagus nerve in the cervical neurovascular bundle are two different variations. The coincidence of right non-recurrent ILN arising from cervical part of the vagus medial to the CCA in the same patient is a very interesting feature. The safety of thyroid operations is dependent to proper identification, dissection and full exposition of ILN. The safe procedure requires complete knowledge on the anatomy of neural structures including all their anatomic variations.
