The nasal septum (septum nasi) is a structure within the nose that separates the left and right nasal cavities. It is composed of both bone and cartilage and plays a crucial role in supporting the nose and regulating airflow.
Anatomy[edit | edit source]
The nasal septum is made up of several components:
- The perpendicular plate of the ethmoid bone forms the superior part.
- The vomer forms the posterior and inferior part.
- The septal cartilage (quadrangular cartilage) forms the anterior part.
Blood Supply[edit | edit source]
The nasal septum receives blood from several arteries:
- The sphenopalatine artery, a branch of the maxillary artery.
- The greater palatine artery, also a branch of the maxillary artery.
- The superior labial artery, a branch of the facial artery.
- The anterior ethmoidal artery, a branch of the ophthalmic artery.
Innervation[edit | edit source]
The nasal septum is innervated by:
- The nasopalatine nerve, a branch of the maxillary nerve.
- The anterior ethmoidal nerve, a branch of the ophthalmic nerve.
Lymphatic Drainage[edit | edit source]
Lymph from the nasal septum drains into the:
Clinical Significance[edit | edit source]
A common condition associated with the nasal septum is a deviated septum, where the septum is displaced to one side, potentially causing breathing difficulties, nasal congestion, and sinusitis. Treatment may involve septoplasty, a surgical procedure to correct the deviation.
