Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.
The sphenopalatine artery passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus.Here it gives off its posterior lateral nasal branches which spread forward over the conchæ and meatuses, anastomose with the ethmoidal arteries and the nasal branches of the descending palatine, and assist in supplying the frontal, maxillary, ethmoidal, and ...
It supplies the ala and dorsum of the nose, anastomosing with its fellow, with the septal and alar branches, with the dorsal nasal branch of the ophthalmic artery, and with the infraorbital branch of the internal maxillary. If the posterior lateral nasal artery is superficial in the nasal wall, a laceration may occur during an aggressive curettage.
It passes anteriorly [citation needed] to exit the orbit between the trochlea (superiorly [citation needed]), the medial palpebral ligament (inferiorly [citation needed]). [1] It gives a branch to the lacrimal sac before bifurcating into two branches: one branch anastomoses with the terminal (angular) part of the facial artery [1] and is important for the blood supply of the face; [citation ...
A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected. [5]
The ophthalmic artery (OA) is an artery of the head.It is the first branch of the internal carotid artery distal to the carotid sinus.Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges.
The sphenopalatine artery is a branch of the maxillary artery which passes through the sphenopalatine foramen into the cavity of the nose, at the back part of the superior meatus. Here it gives off its posterior lateral nasal branches .
The anterior ethmoidal artery is a branch of the ophthalmic artery in the orbit. [1] It exits the orbit through the anterior ethmoidal foramen alongside the anterior ethmoidal nerve.
