The nasal septum can depart from the centre line of the nose in a condition that is known as a deviated septum caused by 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 seven, at which point it will frequently deviate to the right.
Nasal septum deviation is the most common cause of nasal obstruction. [7] A history of trauma to the nose is often present including trauma from the process of birth or microfractures. [ 7 ] A medical professional, such as an otorhinolaryngologist (ears, nose, and throat doctor), typically makes the diagnosis after taking a thorough history ...
The human nose is the first organ of the respiratory system.It is also the principal organ in the olfactory system.The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two.
The nasal septum is the thin wall within the nose separating the nasal cavity. When this tissue is significantly displaced to one side, it can interfere with breathing and cause various symptoms.
A nasal septum perforation is a medical condition in which the nasal septum, the bony/cartilaginous wall dividing the nasal cavities, develops a hole or fissure. [1]This may be brought on directly, as in the case of nasal piercings, or indirectly, as by long-term topical drug application, including nasal administration of ethylphenidate, methamphetamine, cocaine, crushed prescription pills, or ...
The septal nasal cartilage (cartilage of the septum or quadrangular cartilage) is composed of hyaline cartilage. [1] It is somewhat quadrilateral in form, thicker at its margins than at its center, and completes the separation between the nasal cavities in front.
The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.
The nasal septum is composed of cartilaginous, membranous, and bony components overlaid by mucoperichondrium and mucoperiosteum. Bleeding within the confines of the mucoperichnondrium leads to a septal hematoma, where as external bleeding from Kiesselbach's plexus results in epistaxis . [ 3 ]
