The septal nasal cartilage (cartilage of the septum or quadrangular cartilage) is composed of hyaline cartilage. [1] It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.
Right side view of the septal nasal cartilage. The septal nasal cartilage is a flat, quadrilateral piece of hyaline cartilage that separates both nasal cavities from one another. [3] The septal nasal cartilage fits in a place between the perpendicular plate of the ethmoid and vomer bones while also being covered by an internal mucous membrane ...
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 nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone; Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone; The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum. This strip of bone is ...
The major and minor cartilages are also known as the greater and lesser alar cartilages. There is a narrow strip of cartilage called the vomeronasal cartilage that lies between the vomer and the septal cartilage. [9] The septal nasal cartilage, extends from the nasal bones in the midline, to the bony part of the septum in the
Interventricular septum, the wall separating the left and right ventricles of the heart [2] Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue [3] The lingual septum can be seen running vertically through the center of the tongue. Nasal septum: the cartilage wall separating the nostrils of the nose [4]
The anterior border articulates with the spine of the frontal bone and the crest of the nasal bones. The posterior border articulates by its upper half with the sphenoidal crest, by its lower with the vomer. The inferior border is thicker than the posterior, and serves for the attachment of the septal nasal cartilage of the nose.
Harvesting of nasal cartilage is minimally invasive, can be performed in an outpatient procedure under local anesthesia and is associated with minimal morbidity. [6] NC can be isolated from nasal septal cartilage biopsies by enzymatic digestion using collagenase type I, II or IV (at different combination and concentration – varying from 0.15% to 0.6% –) alone or after an initial short pre ...
