RESUMO
This study was carried out on 50 apparently healthy animals [30 dogs and 20 cats] and 15 dogs suffered from skull affections. Animals were subjected to Conventional plain radiographic imaging [lateral, dorso ventral, rostrocaudal, lateral oblique, open-mouth rostrocaudal, open-mouth lateral, open-mouth ventrodorsal and intra-oral positionings]. Also, positive contrast canalography and rhinography were done to visualize, in details, the acoustic canal and nasal structures respectively. The results revealed that the evaluated Conventional plain radiographic positionings were efficient for imaging the skull anatomy and its affections. Canalography can be regarded as an accurate technique to measure the diameter of the horizontal .ear canal and the tympanic membrane which are predictors of ear diseases. Rhinography was found to be valuable in imaging of nasal sinuses and conchae
