septal cartilage การใช้
- The septal cartilage of the nose can be destroyed through repeated nasal inhalation of drugs such as cocaine.
- 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.
- The shape of the nose is determined by the nasal bones and the nasal cartilages, including the septal cartilage ( which separates the nostrils ) and the upper and lower lateral cartilages.
- 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.
