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 called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer ...
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.
The septal nasal cartilage, extends from the nasal bones in the midline, to the bony part of the septum in the midline, posteriorly. It then passes along the floor of the nasal cavity. [10] The septum is quadrangular–the upper half is attached to the two lateral nasal cartilages, which are fused to
Like the septal nasal cartilage, the lateral nasal cartilage is composed of hyaline cartilage. Hyaline cartilage provides form and flexibility within a specific structure. The superior portion of the lateral nasal cartilage fuses with the septum to provide support within the nasal cavities.
A deviated nasal septum doesn’t necessarily cause any symptoms except for difficulty breathing, which, fortunately, hasn’t been an issue for me. “It’s pretty common,” McDonald says.
A deviated septum is an abnormal condition in which the top of the cartilaginous ridge leans to the left or the right, causing obstruction of the affected nasal passage. It is common for nasal septa to depart from the exact centerline; the septum is only considered deviated if the shift is substantial or causes problems. [3]
The remaining cartilaginous part (characterized as hyaline cartilage) of the human nasal septum has a specific three-dimensional organization with regards to local differences in cell size and the amounts of extracellular matrix. In the outer region of the cartilage, NC are numerous, small, flat and oriented parallel to the surface.
The nasal septum is composed of cartilaginous, membranous, and bony components overlaid by mucoperichondrium and mucoperiosteum. Bleeding within the confines of the mucoperichnondrium leads to a septal hematoma, where as external bleeding from Kiesselbach's plexus results in epistaxis . [ 3 ]
