Definition: A calcification in the nasal cavity.
Location: Nasal cavity, will appear superior to the floor of the nasal cavity on a pantomograph.
Edge: Well-defined, smooth or irregular outline.
Shape: Round, ovoid, irregular.
Internal: Radiopaque, may have a ‘laminated’ appearance with radiopaque and radiolucent bands evident due to continued laying down of calcium salts. (This looks similar to layers of an onion.)
Number: Typically single.
TIP: A maxillary standard occlusal radiograph is helpful to determine the location before a cone beam CT is recommended.
