The fleshy external end of the nasal septum is sometimes also called columella.
The nasal septum is composed of three structures:
The nasal septum can depart from the centreline of the nose; this condition is known as a deviated septum. Trauma, excessive nose-picking and cocaine usage can cause septum perforations, or holes developing in the septum.
An operation to the nasal septum is known as a septoplasty.
