septal cartilage

It also articulates with the septal cartilage of the nose.

Saddle nose: Due to over resection of the dorsal wall of the septal cartilage.

The inferior border is thicker than the posterior, and serves for the attachment of the septal cartilage of the nose.

The cartilage of the septum (or septal cartilage, or quadrangular cartilage)is composed of hyaline cartilage.

Nasal septal abscess is a condition of the nasal septum in which there is a collection of pus between the mucoperichondrium and septal cartilage.

Its upper half is fused with the perpendicular plate of the ethmoid; its lower half is grooved for the inferior margin of the septal cartilage of the nose.

Because the septal cartilage has no blood supply of its own and receives all of its nutrients and oxygen from the perichondrium, an untreated septal hematoma may lead to destruction of the septum.

The nasal lining of the distal two-thirds of the nose can be covered with anteriorly based septal mucosal flaps; however, if bilateral septal-flaps are used, the septal cartilage does become devascularized, possibly from iatrogenic septal perforation.

The postero-superior part of this cartilage is ossified to form the perpendicular plate of the ethmoid; its antero-inferior portion persists as the septal cartilage, while the vomer is ossified in the membrane covering its postero-inferior part.

The nasal skeleton is replaced with a rib-graft nasal dorsum and lateral nasal wall; septal cartilage grafts and conchal cartilage grafts are applied to correct defects of the nasal tip and of the alar lobules.
