nässkiljvägg

The term "nässkiljvägg" is a Swedish word that translates to "nasal septum" in English. It refers to the wall of cartilage and bone that divides the nasal cavity into two separate nostrils. This structure plays a crucial role in the respiratory system, ensuring that air flows efficiently through the nose.

The nasal septum is composed of several parts, including the quadrangular cartilage anteriorly and the bony septum posteriorly, which is formed by the perpendicular plate of the ethmoid bone and the vomer. The condition where the nasal septum is deviated or not straight is known as a deviated septum. This deviation can range in severity and may be congenital or caused by trauma.

A deviated nasal septum can obstruct airflow in one or both nostrils, leading to symptoms such as difficulty breathing through the nose, recurrent sinus infections, nosebleeds, and facial pain. In some cases, a deviated septum can contribute to snoring and sleep apnea. Diagnosis is typically made through a physical examination, and treatment options may include nasal sprays, decongestants, or surgical correction, such as septoplasty, to straighten the septum.
