Superior Thyroid Artery Originating from the Ascending Pharyngeal Artery

Background: The superior thyroid artery generally originates from the anterior surface of the external carotid artery. The superior thyroid artery originating from the ascending pharyngeal artery is an extremely rare anatomic variation. Nevertheless, some variations in the origin of the superior thyroid artery have been reported in the literature. Such knowledge is important during neck surgeries such as thyroidectomy and radical neck dissection. Here we report the first case of a superior thyroid artery arising from the ascending pharyngeal artery. Case report: During a routine dissection on the neck, a superior thyroid artery originating from the ascending pharyngeal artery was observed on the right side, in a 37-year-old male cadaver. The superior thyroid artery had two segments, a superior (or horizontal) segment and an inferior (or vertical) segment. The superior segment passed posterior to the linguofacial trunk. The inferior segment passed posterior to the superior laryngeal artery and an artery that went to the infrahyoid muscles. These last two arteries came directly from the external carotid artery. The superior thyroid artery terminated in two branches (one lateral and one medial) 6 mm above the superior pole of the right thyroid lobe. Conclusion: The origin of the superior thyroid artery from the ascending pharyngeal artery is an extremely rare anatomical variation. A thorough knowledge of the variations in origin of the superior thyroid artery is decisive for head and neck surgeries.

Comparison of diffusion ranges at different local anesthetic volumes during superior laryngeal nerve block

ObjectivesUltrasound-guided superior laryngeal nerve (SLN) block is a practical and painless approach to avoid the hemodynamic stress response during endotracheal intubation and relieve sore throat after laryngeal surgery. The main purpose of this study was to establish an optimal dosage of local anesthetic when performing SLN block to help anesthetists balance analgesia and side effects.MethodsTwenty fresh larynx specimens were obtained immediately after resection and then injected with 2-, 3-, 4-, or 5- mL of a lidocaine-blue dye mixture at bilateral SLN puncture sites. Superficial areas of deposited blue dye were measured. Dye leakage and surrounding dyed tissue were recorded. Another 40 patients were included in the ultrasound investigation. Distances between the internal branch of the SLN (iSLN) and adjacent structures were calculated.ResultsThe dye spread area was greater with the administration of larger doses, especially to the visceral space. A 2- or 3-mL injection of local anesthetic was sufficient to infiltrate the SLN gap. A higher incidence of dye leaking out of the thyrohyoid membrane and anterior epiglottis space was observed; furthermore, there was substantially more dyed hyoid/thyroid cartilage with 4 and 5 mL of injected dye mixture than 2 mL. There was no significant difference between the specimen and ultrasound measurements of for length of iSLN-adjacent structures.ConclusionsIn the Chinese population, 2- or 3- mL of local anesthetic is a safe dose during SLN block. A larger volume could overflow from the cavity to cause complications. The thyrohyoid membrane combined with the superior laryngeal artery is a reliable target for positioning the iSLN during ultrasound-guided regional anesthesia.

Superior laryngeal artery originating from the lingual artery.

In most cases, the superior laryngeal artery (SLA) branches from the superior thyroid artery, which, in turn, leaves the external carotid artery. Few dissection studies found previously that the SLA could originate from the lingual artery. We report here probably the first evidence of such a rare anatomical variation found unilaterally in a retrospectively evaluated by computed tomography angiography adult male case. The left SLA left a suprahyoid coil of the lingual artery and continued over the greater hyoid horn to enter the larynx through the thyrohyoid membrane. On both sides, thyroid foramina were found, but only the right one used for the entry of the right SLA. Therefore, the rare SLA origin from the lingual artery can be documented on computed tomography angiograms, which could help during preoperative evaluations and prevent unwanted surgical complications.

Inside-Out Surgical Anatomy of Superior Laryngeal Artery Endoscopic Dissection and Proposal for Nomenclature of Branches.

To describe the inside out surgical anatomy of the superior laryngeal artery and to resolve the ambiguities in the nomenclature of its main branches. Endoscopic dissection of the superior laryngeal artery in the paraglottic space of larynges of fresh frozen cadavers and a review of the literature. A center for anatomy encompassing facilities for latex injection into the cervical arteries of human donor bodies and a laryngeal dissection station equipped with a video-guided endoscope and a 3-dimensional camera. Video-guided endoscopic dissection of 12 hemilarynges in fresh frozen cadavers whose cervical arteries were injected with red latex. Description of the inside-out surgical anatomy of the superior laryngeal artery and its main branches. Review of the previous reports describing the anatomy of the superior laryngeal artery. From inside the larynx, the artery was exposed upon its entry through the thyrohyoid membrane or through the foramen thyroideum. It was traced ventrocaudally in the paraglottic space exposing its branches to the epiglottis, the arytenoid, and the laryngeal muscles and mucosa. Its terminal branch was followed until it left the larynx through the cricothyroid membrane. Branches of the artery, previously described under different names, appeared to supply the same anatomical domains. Mastering the inside out anatomy of the superior laryngeal artery is mandatory to control any intraoperative or postoperative hemorrhage during transoral laryngeal microsurgery or during transoral robotic surgery. Naming the artery's main branches according to their domain of supply would resolve the ambiguities resulting from various nomenclatures.

Variations in the Origin of the Superior Laryngeal Artery and their Clinical Significance: A Case Report with a Proposal for a New Classification

The superior laryngeal artery is the primary vessel providing the blood supply to the larynx. Commonly, it is derived from the superior thyroid artery. Different variations in the origin have been described in the current literature; knowledge of such variations is crucial for various surgical interventions of the larynx and surgical procedures in the lateral region of the neck regarding the carotid triangle. It should be noted that radiological studies, such as selective angiography of the thyroid gland, can also be misleading in cases of variations. Herein, we describe a case of bilateral superior laryngeal artery originating directly from the external carotid artery of the neck. The arteries at first have a transverse course and then pierce through the thyrohyoid membrane alongside internal laryngeal nerves. Moreover, we also review the known variations in the origin of the superior laryngeal artery and propose a new classification of all known variations.

Clinical anatomy of superior laryngeal artery via transoral approach.

ObjectiveHemorrhage is the most common complication caused by transoral laryngopharyngeal surgery. It is believed that proper management of the superior laryngeal artery (SLA), the main feeding artery for the larynx and pharynx, may reduce intra‐ and postoperative hemorrhage incidence. The aim of this study was to illustrate the anatomy of the SLA via transoral endoscopic approach.MethodsFourteen sides of SLA from heads of seven fresh‐frozen and silicone‐injected cadavers were dissected. Transoral dissections were performed for the intra‐laryngeal segment of SLA, and transcervical dissections were performed to confirm the anatomical measurements.ResultsSLA had a slightly descending course from the origin to the larynx, and there was a major branch supplying the epiglottis, named pharyngo‐epiglottic artery (PEA). Parallel with the internal superior laryngeal nerve (ISLN), SLA passed through the thyrohyoid membrane and ended into the hypopharynx. The distance from SLA to the superior horn of thyroid cartilage (SHTC) was (9.11 ± 0.58)mm on the left and (9.01 ± 0.37)mm on the right; the distance from SLA to the inferior margin of the hyoid bone (IMHB) was (2.00 ± 0.11)mm on the left and (1.95 ± 0.08)mm on the right; the distance from SLA to ISLN was (5.98 ± 0.48)mm on the left and (5.78 ± 0.36)mm on the right. No significant difference was found between bilateral sides (p > 0.05). Moreover, the distance from SLA to superior margin of thyroid cartilage (SMTC) was (5.52 ± 0.24)mm on the left and (5.80 ± 0.15)mm on the right. A significant difference was also found between bilateral sides (p = 0.03), which might suggest the SLA is located further from the SMTC on the right side.ConclusionSHTC, SMTC, and IMHB could be regarded as anatomical landmarks to locate SLA when applying a transoral approach. Moreover, a complete understanding of the detailed anatomy of the superior laryngeal artery may improve the detection of hemostasis in transoral laryngeal or hypo‐pharyngeal surgery.

Magnetic resonance angiographic study of the variations in the branching pattern of external carotid artery

Knowledge of anatomy of the branching pattern of external carotid artery (ECA) is needed for head and neck surgeries and diagnostic purposes. Previously knowledge regarding this was obtained from dissecting specimens. But with magnetic resonance angiograms being done widely, data from these may be taken for a better understanding of the branching pattern of ECA. To study the branching pattern of external carotid artery using MR angiograms taken for other purposes. A cross-sectional study was carried out in our institution, which is a tertiary care centre, between September 2013 and September 2015 in which we studied the MR angiograms of 50 patients. Out of the 50 MR angiograms studied, variations were seen in 5 cases. In two cases, the ascending pharyngeal artery was seen to arise from the lateral side instead of the medial side on the left side. In another two, the ascending pharyngeal artery was seen to arise from the occipital artery on the left side. In one case the superior laryngeal artery arose from the external carotid artery. MR angiogram taken for other purposes is an inexpensive, ionizing radiation free method which can be used to study the branching pattern of external carotid artery.

Solitary fibrous tumor of the larynx treated with transoral endoscopic CO2 laser surgery – a case report and literature review

Presented is a case of an exceptionally rare laryngeal tumor removed by means of endoscopic surgery using a CO2 laser following earlier embolization of the left superior laryngeal artery. From the patient’s perspective, it is extremely important that the procedure be performed in a possibly least invasive manner so that no laryngeal or pharyngeal dysfunctions develop as the consequence thereof. </br> </br> Due to the total nature of the resection with negative (R0) resection margins being achieved, and due to the histopathological examina-tion being suggestive of the benign nature of the lesion, no adjuvant treatment was required in the reported case. </br> </br> Due to the sporadic incidence of SFTs within the laryngeal region and the incompletely studied biology of these tumors, long-term follow-up in the setting of an outpatient laryngological clinic is advisable.

The Superior Laryngeal Nerve and Its Vulnerability in Surgeries of the Neck.

Anatomical considerations of the superior laryngeal nerve (SLN), a branch of the vagus, provides information to minimize the potential for iatrogenic intraoperative injury, thereby preventing motor and sensory dysfunctions of the larynx. The present study aims to assess the variation of the SLN and its relationship to the superior thyroid artery (STA) and superior laryngeal artery (SLA). The study was done on 35 formalin-fixed cadavers at Oakland University in 2018–2019. In our study, we found that out of 21 cadavers, 52.4% of the external laryngeal branches (ebSLN) are related posteromedial to the STA, while 47.6% are related anteromedial to it. Out of 14 cadavers, 64.3% of the internal laryngeal branches (ibSLN) are related superoposterior to the SLA, while 35.7% are inferoposterior to it. In most cases, the SLA crosses above the ebSLN while traveling to pierce the thyrohyoid membrane to reach the larynx. The data demonstrate that both the ebSLN and ibSLN display variation in their relationship with the STA and the SLA, respectively. Awareness of these variable relationships is critical for identification and isolation of these structures in order to prevent consequences of nerve injury, primarily a reduction in the highest attainable frequency of the voice and aspiration pneumonia.

Early Internal Branch of Superior Laryngeal Nerve Bifurcation Passes Through Double Thyroid Foramen.

Internal branch of superior laryngeal nerve (ibSLN) provides sensory innervation mostly to the supraglottic part of the larynx and thus prevents aspiration during ingestion. Normally, it is distributed to the larynx after piercing the thyrohyoid membrane above the superior laryngeal artery. Multiple anatomical variations in the course of ibSLN have been reported. An early ibSLN bifurcation and course through double thyroid foramen constitutes an interesting anatomical variation that may easily lead to an injury during procedures in the thyroid gland and the larynx. Knowledge of the anatomical variability is essential in order to prevent surgical complications that could potentially impact the patient's quality of life.

BACKGROUND External carotid arteries account for a major share of arterial supply of head and neck regions. As variations are frequently observed in the branching pattern of external carotid artery, surgeons, radiologists and anaesthetists often encounter difficulties in various procedures of head and neck. The purpose of this study is to describe the variations in the branching pattern of external carotid artery as observed in South Indian population which definitely reduces its iatrogenic injuries associated with surgical and radiological procedures of head and neck. METHODS This is cross-sectional descriptive study. Bilateral neck dissection was done on twenty-two formalin fixed cadavers to study the branching pattern of external carotid artery during a period of two years in the Department of Anatomy in Government Medical College, Alappuzha. Common carotid, external carotid and internal carotid arteries were dissected. All the branches of external carotid artery were traced and the variations were noted. The distance between carotid bifurcation and point of origin of individual branches of external carotid were measured and statistically analyzed. RESULTS In the present study along with normal branching pattern of external carotid artery, variations like origin of superior thyroid artery from common carotid artery and also from carotid bifurcation were seen. A common linguofacial trunk and direct origin of superior laryngeal artery from external carotid artery were also observed. CONCLUSIONS Prior knowledge of the variations will be helpful to surgeons and anaesthetists while dealing with these vessels during procedures of head and neck regions.

ЗАКОНОМЕРНОСТИ АНАТОМИИ И ТОПОГРАФИИ ГОРТАННЫХ НЕРВОВ У ВЗРОСЛОГО ЧЕЛОВЕКА ПО ДАННЫМ ЛИТЕРАТУРЫ

Establishing the morphological regularities of laryngeal nerves of the human is extremely important in surgical and oncological practice. During surgical intervenrions on the thyroid gland, damage of the superior and inferior laryngeal nerves can occur — the second most common complication after hypoparathyroidism. Based on the studied literature data on anatomy and topography of the laryngeal nerves in an adult, a number of the morphological features have been identified. The article describes the morphometric parameters of the laryngeal nerves and their branches. Also, the article describes variants of the localisation of the internal branch of the superior laryngeal nerve relatively to the superior laryngeal artery, a number of classifications based on the localisation of the external branch of the superior laryngeal nerve relatively to the superior thyroid artery and the inferior laryngeal constrictor, variants for the inferior laryngeal nerve passage in tracheoesophageal groove, its location in relation to the trunk and branches of the inferior thyroid artery, Berry's ligament, Zuckerkandl's tubercle and also such anatomical features of the inferior laryngeal nerve as its extralaryngeal branching and cases of non-recurrent laryngeal nerve. These topographic and anatomical features of the laryngeal nerves that should be taken into account for the identification of the nerves during surgery, and also allows them to be considered prerequisites for an increased risk of iatrogenic trauma.

Topographic anatomy of the ınternal branch of the superior laryngeal nerve.

The aim of this study was to investigate the surgical and topographical anatomy of the internal branch of the superior laryngeal nerve (ibSLN) in laryngectomy patients. Patients aged 36-90years old who underwent a total laryngectomy operation with a diagnosis of laryngeal carcinoma participated in the study. Fifteen patients who underwent a total laryngectomy operation between June 2015 and November 2016 were included in the study. A total of 29 superior laryngeal nerves (SLN) of 15 patients were studied. The position of the nerve was photographed before the thyrohyoid membrane (THM) was passed during dissection. The relationship and course of the ibSLN with respect to the superior laryngeal artery (SLA) were observed. The distance to adjacent formations and branching variants were examined along the course of the nerve. Of the total 29 ibSLN, 17 were divided into three branches and 12 into two branches. In all cases except for one, the ibSLN course after piercing the THM was determined. The ibSLN penetrated the THM at a mean of 12.0 ± 2.61mm (6-16mm) from the superior border of the thyroid cartilage. The ibSLN penetrated the THM with a mean distance of 9.34 ± 1.65 (6-12) mm from the inferior border of the hyoid bone. Our study demonstrated the surgical and topographical features of the ibSLN with respect to the THM, and provided a more precise knowledge of its anatomy in laryngectomy patients. It thus may help head and neck surgeons identify this nerve.

The Superior Laryngeal Nerve and its Vulnerability in Surgeries of the Neck

Knowledge of anatomical considerations of the superior laryngeal nerve, a branch of the vagus, provides information to prevent intraoperative injuries and associated dysfunctions. The superior laryngeal nerve has external and internal branches providing motor innervation to the cricothyroid muscle and sensory innervation to the supraglottic mucosa of the larynx, respectively. The external laryngeal branch travels for a relatively greater distance together with the superior thyroid artery and the internal laryngeal branch accompanies, for a shorter distance, the superior laryngeal artery, though their relationship with their respective artery varies. Isolation and identification of the superior pole and superior laryngeal vessels, which are intimately related to the external and internal laryngeal branches, respectively, is clinically important. Both branches can potentially be severed, compressed, or stretched during surgical procedures of the neck such as thyroidectomy and anterior cervical discectomy. Injury to the external laryngeal nerve results in a reduction in the highest attainable frequency of the voice, while injury to the internal laryngeal nerve results in a loss of sensation in the laryngeal vestibule, increasing the risk of aspiration pneumonia. The consequences of superior laryngeal nerve injury are variable in growing literature and are commonly disregarded compared to the recurrent laryngeal nerve. The present study aims to assess the anatomical considerations of the superior laryngeal nerve pertaining to its course and relationship to the superior thyroid and superior laryngeal arteries. The study was done on 35 formalin‐fixed cadavers at Oakland University William Beaumont School of Medicine in 2018–2020. Following critical observation and careful dissection, photographs were taken and the data was analyzed quantitatively and in a descriptive manner. In our investigation, we found that out of twenty‐one cadavers, 52.4% of the external laryngeal branches are related posteromedial to the superior thyroid artery, while 47.6% are related anteromedial to it. On the other hand, our findings indicate that out of fourteen cadavers, 64.3% of the internal laryngeal branches are related superoposterior to the superior laryngeal artery, while 35.7% are inferoposterior to it. In addition, in most cases, the superior laryngeal artery crosses above the external laryngeal branch while traveling to pierce the thyrohyoid membrane to reach the larynx. The data portrays that both the external and internal laryngeal branches display a variation in their relationship with the superior thyroid artery and the superior laryngeal artery. The findings show a clinically important variation in the course and relationship of the superior laryngeal nerve and its related vessels, especially the posteromedial and superoposterior relationships, which exposes the nerves during ligation of the respective vessels. Awareness of these variable relationships is critical for identification and isolation of the neurovascular structures in order to preserve the nerve, prevent a reduction in the highest attainable frequency of the voice, and minimize the risk of aspiration pneumonia during surgical procedures of the neck.

Origin of superior thyroid artery and superior laryngeal artery - A cadaveric study

Origin of superior thyroid artery and superior laryngeal artery - A cadaveric study

Anatomical Cadaver Study of Endolaryngeal Vascularization: Focus on the Glottis, Supraglottis, and Subglottis From the Transoral Microsurgical Point of View.

Carbon dioxide laser coagulation during transoral laser microsurgery (TLM) for laryngeal cancer allows control of bleeding from vessels smaller than 0.5 mm. Therefore, larger arteries and veins must be carefully managed by clipping and/or monopolar cautery. The aim of this paper is to detail endolaryngeal vascular anatomy and identify areas of possible bleeding during TLM. We performed an anatomical study on a series of 11 fresh-frozen human cadavers. After injection of a bicomponent red silicone into the innominate, left common carotid, and left subclavian arteries, 22 hemilarynges were dissected, the course of the supraglottic, glottic, and subglottic vessels were traced after microdissection of the intervening structures, and their size measured at specific landmark points where such vessels are more frequently encountered during TLM. Three vessels arising from the superior laryngeal artery were identified after its entry point at the level of the thyro-hyoid membrane: (1) the epiglottic artery (EA), documented in 100% of cases, a common trunk dividing into two main vessels (2) the postero-inferior artery (PIA), present in 100% of the specimens, running downward and dividing in a posterior (pPIA), and anterior (aPIA) branches (3) the antero-inferior artery (AIA), present in 95% of our specimens, running downward to the anterior commissure (AC). Two transverse anastomotic networks (TANs) connected the AIA and PIA, both parallel to the vocal muscle, one lateral (present in 100% of cases), and another medial (91% of specimens). Finally, a fourth vessel supplying the glottic plane was found to be the endolaryngeal paracommissural branch of the crico-thyroid artery (PCA), arising from the inferior laryngeal artery and emerging just below the AC, through the crico-thyroid membrane (reported in 100% of the specimens). This vessel anastomosed in 91% of cases with the AIA, through one or both of the TANs. The course of the endolaryngeal arteries, their relationships with adjacent structures, and size at specific landmark points have been herein described in order to provide surgeons with a map to guide them during the steep learning curve of transoral surgery of the larynx, with special emphasis given to TLM.

Variations in the origin of superior laryngeal artery.

The superior laryngeal artery is the principal artery supplying the laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of superior laryngeal artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for laryngeal and hypolaryngeal cancers. However, relatively few studies have been done on the superior laryngeal artery in comparison to its clinical importance. The present study was aimed at documenting the prevalence of variable origin of the superior laryngeal artery within the carotid triangle. Sixty hemi-necks obtained from 30 South Indian cadavers were dissected and studied for variations in the origin of superior laryngeal artery. It was observed that the superior laryngeal artery took origin from superior thyroid in 91.7% cases. Variable origin from the external carotid artery was noted in 5% cases. The superior laryngeal artery was found to arise from the lingual artery in one case alone (1.7%). In addition to the above findings, a very rare variation of superior laryngeal artery arising from the ascending pharyngeal (1.7%) was also observed in the hemi-neck of one cadaver. All the variations that were observed were unilateral and on the left side. These findings may help provide further insight to the anatomists, radiologists and surgeons and can help improve performances during surgical manipulations of the larynx.

Resection of a laryngeal hemangioma in an adult using an ultrasonic scalpel: A case report.

Adult laryngeal hemangioma is an extremely rare and slowly progressing vascular tumor. The present study describes the first reported case of a male with a large laryngeal hemangioma that was treated by ultrasonic scalpel. A 61-year-old male presented to our hospital with a recurrent pharyngeal foreign body sensation, without hoarseness, hemoptysis, expectoration or dyspnea. A blue-black mass was detected in the right pyriform sinus, with a morular surface and a wide pedicle positioned lateral to the right arytenoid cartilage and aryepiglottic fold under electronic laryngoscopy. Following tracheotomy under local anesthesia, right superior laryngeal artery ligation and laryngeal hemangioma resection via a lateral neck hypopharyngeal approach were performed under general anesthesia using an ultrasonic scalpel. Pathological examination verified that the tumor was a cavernous hemangioma. On day 11, subsequent to post-operative anti-inflammatory and symptomatic treatment, electronic laryngoscopy showed that the arytenoid mucosal edema had decreased and that the movement of the arytenoid was good. There was no recurrence of hemangioma during a 2-year follow-up period. Therefore, it is recommended that complete surgical resection using an ultrasonic scalpel should be considered for similar cases involving large laryngeal hemangiomas.
