Common nasal symptoms include blockage, runny nose (rhinorrhea), sneezing, bleeding, hyposmia (reduced sense of smell). Conditions include allergy, infection and tumor.
Sinusitis is a common infection involving the sinuses which are air spaces next to the nasal cavities. Also known as rhinosinusitis, it presents with thick nasal discharge, blocked, reduced sense of smell, pain, cough, headache.
Nasal polyps are a more severe form of sinus infection resulting from the swelling of the sinus cavities lining. Nasal blockage and loss of sense of smell are common symptoms. On examination, endoscopy will reveal grape-like swellings in the nasal cavities.
Epistaxis (bleeding from the nose) usually results from trauma eg nose digging, sports injury, fights, falls. It can also result from infection and tumor.
Deviated nasal septums are found in some degree in up to 90% of the population. Not all deviated nasal septums cause symptoms. Significant deviated nasal septums usually cause unilateral (one-sided) nasal blockage. They are easily detected on direct examination of the nasal cavities.
Nose cancer is almost exclusively a Chinese cancer. The most common presentation is a neck swelling, not nasal symptoms. Common nasal symptoms include unilateral nasal blockage and epistaxis.
