“…However, in 2014, an angiographic study showed that 71.5% of cases had the STA arising from the ECA, 21.5% from the carotid bifurcation, and 1 case had the STA originating from the ICA as seen in our cadaver [11]. This report correlates with one of the most recent papers where 60 adult heminecks showed that in 88% of cases, the STA had its origin from the ECA, while 8% was found originating from the CCB [12]. With such a vast difference in its anatomical location, questions must arise about the implications these abnormalities can pose to patient care and the surgeries performed in this region.…”

Anatomical anomalies in the human body are common, and their description helps physicians and surgeons during treatment. This article presents the discovery of an abnormal arterial branch originating from the internal carotid artery (ICA). Typically, this artery does not give off branches until it passes through the carotid canal, but during a cadaveric dissection of a 58-year-old female, the superior thyroid artery (STA) was found to be originating from the ICA. Some common variations of the origin of the STA are the common carotid and at the bifurcation of the Common carotid, but rarely, has it been seen origination from the ICA. No known health implication of this variation has been reported, although surgeries can become difficult since the artery is used as an anatomical landmark.

“…Nosotros no encontramos nacimientos en este último nivel. Sreedharan et al (2018) en 30 cadáveres econtraron que el 88 % de las ATS nacía de la ACE, mientras que el 8 % lo hacía de la BC y el 4 % de la ACC. En este trabajo se relata que en dos casos en que la ATS nacía a nivel de la ACC no se presentaron entrecruzamientos con el RLNLS (Sreedharan et al).…”

MEDINA-RUIZ, B. A.; MEDINA-IZCURDIA, J. J.; MEDINA-IZCURDIA, B. A.; MARTÍNEZ-VERA, R. B.; MARTÍNEZ-VERA, P. R.; IZCURDIA, C. E. & OTTONE, N. E. Anatomía topográfica del nervio laríngeo superior: Importancia quirúrgica en las tiroidectomías. Int. J. Morphol., 38(4):766-773, 2020. RESUMEN:En las cirugías sobre la glándula tiroides se ha prestado mucha atención al manejo del nervio laríngeo inferior y de las glándulas paratiroides, no así del ramo lateral del nervio laríngeo superior, el cual es satélite del pedículo vascular superior de la glándula tiroides. El manejo del polo superior de la glándula tiroides requiere de un conocimiento acabado de su anatomía topográfica del área y está determinada por sus relaciones más importantes, dadas por el citado nervio y la arteria tiroidea superior principalmente. En este trabajo se pretende estudiar estas relaciones en base a la disección meticulosa del triángulo laringo-esternotiroideo ("Triángulo de Joll") de 25 cadáveres adultos formolizados. Como hallazgo relevante se informa que los "nervios en riesgo", según la clasificación de Cernea, que se basa en una distancia menor a un centímetro en el entrecruzamiento del nervio con la arteria tiroidea superior con respecto al polo superior de la glándula tiroides, es del 52 % para el lado derecho y 44 % para el lado izquierdo del cuello. El origen bajo de la arteria a nivel de la bifurcación carotídea se presenta asociada a un mayor número de "nervios en riesgo" en el lado izquierdo. Según el punto de penetración del ramo lateral del nervio laríngeo superior en el músculo constrictor inferior de la faringe se establece la clasificación de Friedman, muy útil sobre todo en cirugías ayudadas por la neuroestimulación. En esta clasifiacción los "nervios en riesgo" son aquellos que transcurrren superficial al músculo, mientras que los "nervios protegidos" serían aquellos que perforan el músculo en su porción superior. En este trabajo los "nervios en riesgo" se presentaron del lado izquierdo en el 56 % de los casos y del derecho en el 60 %, mientras que los "nervios protegidos" en el 24 % y 16 %, respectivamente.PALABRAS CLAVE: Ramo lateral del nervio laríngeo superior; Arteria tiroidea superior; Polo superior de la glándula tiroides; Anatomía topográfica.

Background: The superior thyroid artery (STA) is the dominant arterial supply of the thyroid gland, larynx and the neck. Knowledge of these variations is crucial for decreasing morbidity during the surgeries. The present study was undertaken to evaluate the frequency of usual anatomical variations in the origin of STA in human cadavers. Method: The origin of STA was studied by dissecting hundred human carotid specimens obtained from the formalin embalmed cadavers who were allotted to the undergraduate students for dissection in the Department of Anatomy. Results: STA arose commonly from external carotid artery (ECA) in 71 cases (71%), arising directly from common carotid artery (CCA) in 24 (24%) cases whereas only in 5 specimens (5%) it was arising at the level of bifurcation of CCA. On the right side STA was originated from ECA in 31(43.7%) and on left side it was 40(56.3%). STA was originated at bifurcation level in 5(100%) cases on right side and on left side no case was observed (0%). On right side STA was originated from CCA in14 (58.3%) cases and on left side in 10(41.6%) cases. Conclusion: The wide range of variations of the STA on its origin, course, branching patterns and relationship with adjacent structures is a common phenomenon. Thus, the deep knowledge concerning the origin and branching pattern of STA is essential in enhancing precision and decreasing morbidity related to the surgical and interventional radiological head and neck procedures.
