What is a lingual artery?
The lingual artery is a branch of the external carotid artery between the superior thyroid and facial arteries. The lingual artery courses medially to the greater horn of the hyoid bone and crosses inferiorly and facially around the hypoglossal nerve.
What are the 8 branches of ECA?
The ECA is the main feeding vessel to the tissues of the head and neck region through its 8 branches, namely the superior thyroid artery (STA), ascending pharyngeal artery (APA), lingual artery (LA), facial artery (FA), occipital artery, posterior auricular artery (PAA), superficial temporal artery, and maxillary …
What does the ECA feed?
The ECA supplies the superficial temporal artery, occipital artery, and several other superficial arteries.
Is there a main artery in your tongue?
Blood Supply to Gustatory Papillae The main artery supplying the tongue with blood in mammals is the lingual artery, which is usually a branch of the external carotid artery (Figs. 10.8 and 10.10). Study of the tongue’s vascular system historically parallels that of the lingual papillae.
Can you bleed out from the lingual artery?
Clinical Significance. Because of its placement, there is a risk of lingual artery bleeding during particular head and neck surgeries. It’s important for surgeons to understand the artery’s placement, including possible anatomic variations, to prevent injury and complications.
What is ECA stenosis?
External carotid artery (ECA) stenosis is an independent mortality predictor. Additionally, concomitant ECA and internal carotid artery (ICA) stenosis progression has been associated with an increased risk of ipsilateral ischemic events in asymptomatic patients.
What is the circle of Willis?
The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
Where is the ECA located?
Origin and course. The ECA begins at the level of the upper border of the thyroid cartilage (at the level of the fourth cervical vertebra). It takes a slightly curved course upwards and anteriorly before inclining backwards to the space behind the neck of the mandible.
What causes varices on the tongue?
Sublingual varices are clinically characterised by small dilated veins under the lateral borders of the tongue. Their pathogenesis may be due to a change in the connective tissue or weakening of the venous wall, as a result of degeneration of elastic fibres related to the ageing process [3–5].
Which part of the face or oral cavity receives its blood supply from the lingual artery?
The tongue receives its blood supply primarily from the lingual artery, a branch of the external carotid artery.
How do you manage a sublingual hematoma?
In addition, the clinical management of sublingual hematoma includes control of spontaneous bleeding by correction of anticoagulation with or without surgical drainage. There have been sporadic reports that the use of leeches to break down the hematoma can yield good results.
