The external lateral nasal artery (a. nasalis lateralis externa), also known as the external nasal artery, is one of the branches of the external carotid artery and is responsible for the blood supply to the lateral wall of the nose and its paranasal sinuses. It runs in the lateral wall of the nose under the skin and cartilage, and then branches into small vessels that supply the tissues of the lateral walls of the nose, the ethmoid bone, the frontal sinus and the maxillary sinus.
The nasal external lateral artery is a very important artery in the human body, as it supplies blood to tissues that are involved in breathing, smell, mucus secretion and protection against infections. Disruption of the blood supply to this artery can lead to various diseases, such as sinusitis, rhinitis, sinusitis and other infectious diseases of the nose.
For the treatment and prevention of diseases associated with the external lateral nasal artery, it is recommended to undergo regular medical examinations, monitor the hygiene of the nasal cavity and use products to protect against infections and allergies. If you have problems with this artery, you need to see a doctor for diagnosis and treatment.
