Deviated Nasal Septum

See nasal septum.... deviated nasal septum

Nasal Septum

The dividing partition inside the nose. The nasal septum consists of cartilage at the front and bone at the rear, both of which are covered by mucous membrane.

Disorders include a deviated septum (twisting of the septum to one side), which may be present from birth or caused by injury. Surgery may be needed if breathing is obstructed.

Injury may also cause a haematoma (a collection of clotted blood) to form between the cartilage of the septum and the wall of one nasal cavity. A haematoma may obstruct breathing and may become infected, causing an abscess that could require surgical drainage.

Rarely, a hole may be eroded in the nasal septum by tuberculosis, syphilis, Wegener’s granulomatosis, or as a result of sniffing cocaine.... nasal septum
