Sinonasal tumours are rare types of tumours that occur in the nasal sinuses or nasal cavity. These tumours can be cancerous or noncancerous. Signs and symptoms of nasal tumours include stuffy nose, headache, coughing up mucus, a bloody nose or bloody spit, snoring, pus draining from the nose and throat and the ears. Frequently these symptoms are concentrated on only one side of the nose. Also, one may experience pain below the eyes on one side, or double vision. In Australia, sinonasal tumours occur in 5-10 males/million and 2-5 females/million.
