“…posterior cricoarytenoid (PCA) muscles receive any kind of nerve fibers from posterior division of the ILN. These fibers contribute innervations of PCA muscle [14, 15]. On the other hand, Maranillo et al [16] have reported that PCA muscles, the only abductor muscle of the larynx receive motor fiber from anterior division of the ILN.…”

Background. Complete anatomic knowledge including all variations of the inferior laryngeal nerve (ILN) is mandatory for thyroid surgeon. Extralaryngeal terminal division (ETD) of the ILN has significant importance for the safety of thyroidectomy. Material and Methods. Surgical dissection of 200 ILNs was performed on 100 cases. The presence of ETD of the nerve was determined intraoperatively. We propose by a surgical point of view a regional (segmental) classification of ETD of the ILN along its cervical course. Results. ETD has been observed in 54/200 nerves (27%). Great majority are bifurcated nerves (trifurcation 2%). Four types of ETD are classified. In type 1 (arterial; 46.3%), ETD has occurred near inferior thyroid artery (ITA). In type 2 (postarterial; 31.5%), division has been found on postarterial segment. In type 3 (prelaryngeal; 11%), division has been located very close to laryngeal entry point. In type 4 (prearterial; 11%), ETD has occurred before the nerve crossing the ITA. Conclusions. ETD of the ILN is a common anatomical variation. The bifurcation occurs in the ILN at various distances from laryngeal entry point. The classification increasing surgeons' awareness may help to simplify identification and exposure of terminal branches. Preservation of both extralaryngeal terminal branches of the ILN has paramount importance for the safety of thyroid operations.

A brief history of topographical anatomy

This brief history of topographical anatomy begins with Egyptian medical papyri and the works known collectively as the Greco-Arabian canon, the time line then moves on to the excitement of discovery that characterised the Renaissance, the increasing regulatory and legislative frameworks introduced in the 18th and 19th centuries, and ends with a consideration of the impact of technology that epitomises the period from the late 19th century to the present day. This paper is based on a lecture I gave at the Winter Meeting of the Anatomical Society in Cambridge in December 2015, when I was awarded the Anatomical Society Medal.

Intraoperative complications of neck surgery are uncommon and rarely life-threatening and exact anatomical knowledge and precise dissection are most important for prevention. Anatomical variants (e.g. non-recurrent nerve, extralaryngeal branching) predispose to damage of the recurrent laryngeal nerve. The use of intraoperative neuromonitoring (IONM) can prevent bilateral nerve damage but in cases of accidental nerve damage primary reconstruction can improve vocal cord function. Autotransplantation of parathyroid tissue can reduce the rate of hypoparathyroidism but cannot be postulated as a routine measure. Intraoperative bleeding can usually be well controlled and greater danger for the patient emanates from early postoperative bleeding for which many techniques (clip, ligature, vessel sealing) can be employed for prevention. Lesions of the thoracic duct can be controlled by clip, ligation or stitch. Smaller lesions of the trachea and esophagus can be secured with direct suture or muscle flap plasty. In cases of larger lesions plastic reconstruction or organ replacement can be necessary.

Functional anatomy of the recurrent and superior laryngeal nerve

Abstract: The increased knowledge in neurolaryngology provides the basis for a selective neuromonitoring to lower the risk of laryngeal paralyses after thyroid surgery.
