The nasal septum is the septum that divides the nasal cavity into two halves. It consists of an anterior cartilaginous and a posterior bony part. The septum plays an essential role in the structure of the nose and significantly influences nasal breathing.
Layout and function:
The nasal septum comprises cartilage and bone and is covered with mucous membranes. It provides structural support to the nose and ensures air flows evenly through both nostrils. A well-aligned nasal septum allows for efficient air circulation, humidifying, warming, and filtering air before it enters the lower respiratory tract.
Septal deviation:
A common nasal septum disorder is septal deviation, in which the septum deviates from the midline. This can be congenital or caused by injury, such as a broken nose. A deviated septum can lead to problems such as obstructed nasal breathing, chronic nasal congestion, headaches and snoring.
Diagnosis and treatment:
Diagnosing a deviated nasal septum is made through a clinical examination, often supplemented by imaging procedures such as digital volume tomography (DVT) or computed tomography (CT). Treatment ranges from conservative measures such as appropriate nasal sprays to surgical correction, known as septoplasty. The nasal septum is straightened to improve the passage of air.
The nasal septum is very important for nasal breathing and overall nasal health. Correctly diagnosing and treating nasal septum problems is essential to improve respiratory function and relieve associated discomfort.
