The nasals are a pair of bones in the skull of many animals. They are connected to each other in the midline of the skull, and are usually bordered by the premaxilla, maxilla, and frontal bone, though this may vary with species.
But in some cases, your signs and symptoms may be due to nasal polyps — soft, noncancerous (benign) growths that develop on the lining of your nose or sinuses.
Nasal polyps result from chronic inflammation in the lining of your nose or sinuses, but just what triggers the inflammation isn't always clear.
Although nasal polyps can affect anyone, they're more common in people older than 40 and in adults and children with conditions such as asthma, chronic sinus infections, hay fever and cystic fibrosis.
