When the bone and cartilage dividing your nasal cavity is off-center or crooked, the condition is referred to as a deviated septum. If the deviation is serious enough, it can cause breathing difficulties and chronic sinus conditions that require treatment.
Symptoms
The perfect nasal septum divides the left and right nostrils evenly, but this is pretty rare; it’s estimated that about 80% of the population has a septum that is off-center to some extent. Usually, the deviation is slight and goes unnoticed; only the worst cases produce symptoms that affect breathing. Symptoms include nasal congestion (often limited to one side of the nose), frequent nosebleeds and sinus infections, facial pain and pressure, headaches, postnasal drip, and noisy breathing or snoring during sleep.
