A radiographic study was performed on the maxilla of two healthy dogs to assess the effect of replacement of air by fluid and removal of conchae on the radiographic appearance. The purpose was to determine the significance of the presence or absence of the fine trabecular pattern on radiographs of the canine nasal cavity. The results indicate that the radiographic appearance of the maxillary conchae is primarily based on the presence of soft tissues covering the bony conchae, in combination with surrounding air. The radiographic appearance of the ethmoidal conchae is caused by the bony structures themselves. It is concluded that a loss of the characteristic parallel pattern in the cranial part of the nose is primarily the result of silhouetting of maxillary conchae by fluid. A loss of the fine trabecular pattern is caused by destruction of conchae.
