The fleshy external end of the nasal septum is sometimes also called columella.
The nasal septum is composed of five structures:
- perpendicular plate of ethmoid bone
- vomer bone
- cartilage of the septum
- crest of the maxillary bone
- crest of the palatine bone
The nasal septum can depart from the centre line of the nose in a condition is known as a deviated septum due to trauma. However, it is normal to have a slight deviation to one side. The septum generally stays in the midline until about the age of 7, at which point it will frequently deviate to the right.
A perforated nasal septum can be caused by an ulcer, trauma due to an inserted object, excessive nose-picking, long-term exposure to welding fumes, or cocaine abuse. There is a procedure that can be of help to those suffering from perforated septum. A silicone button can be inserted in the hole to close the open sore. An operation to the nasal septum is known as a septoplasty.
The inferior part of the nasal septum can be pierced, usually through the soft tissue but the piercing can also transverse (partially) the cartilage of the septum.
