The symptoms of a deviated nasal septum can vary significantly from person to person. Some individuals with a mild deviation might not exhibit any obvious clinical symptoms and are only diagnosed during a physical examination or an endoscopic nasal examination. However, if the deviation is more pronounced, it may cause various symptoms such as nasal congestion, runny nose, nosebleeds, headaches, and dizziness. In some cases, it can also lead to sinusitis, characterized by sudden acute purulent nasal discharge, nasal congestion, headaches, and a reduced sense of smell. Overall, this is a relatively common condition and most patients see good results after timely and standard medical treatment.
