The sphenopalatine artery is the artery commonly responsible for epistaxis (difficult to control bleeding of the nasal cavity, especially the posterior nasal cavity). [3] In severe nose bleed cases which do not stop after intense packing of anti-clotting agents, the sphenopalatine artery can be ligated (clipped and then cut) during open surgery ...
The arteries that supply Kiesselbach's plexus (responsible for anterior nosebleeds) The nasal mucosa contains a rich blood supply that can be easily ruptured and cause bleeding. Rupture may be spontaneous or initiated by trauma.
a posterior ethmoidal artery, a branch of the ophthalmic artery, a branch of the internal carotid artery. [1] There is contention as whether this is truly part of Kiesselbach's plexus. Most sources quote that it is not part of the plexus, but rather one of the blood supplies for the nasal septum itself.
Woodruff's plexus is located on the lateral wall of the nasal cavity below the posterior end of the inferior nasal concha (turbinate). [3] The plexus contains both arteries and veins which lie in a thin mucosa. [4] The major arteries supplying the plexus are the sphenopalatine artery and ascending pharyngeal artery. [5]
The posterior septal artery passes through the sphenopalatine foramen to enter the nasal cavity. [2] To enter the posterior border of the nasal septum, the posterior septal artery travels along the anterior wall of the sphenoid sinus passing by the sphenoid ostium and choana. [1] This part of the posterior septal artery is called the sphenoidal ...
Coronary artery bypass grafting (CABG): A bypass surgery improves blood flow to your heart by taking another blood vessel from somewhere else in your body and using it to create a new passage for ...
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 ...
The exact mechanism for the formation of hematoma from nasal trauma is controversial, but thought to occur in nasal septal hematomas when there is forced to the nasal cartilage. The force causes the perichondrial blood vessels to leak and rupture in the nasal septum. [7] The cartilage in the septum is avascular and can be 2–4 mm thick.
