PSITTACINE PARANASAL SINUS—A NEW DEFINITION OF COMPARTMENTS

摘要: Documentation of the psittacine paranasal sinuses has been limited. To provide more published detail, spiral computed tomography (CT) was used to scan cephalic and cervical region from cadavers 10 birds (Ara ararauna, Ara chloroptera, macao, Anodorhynchus hyacinthinus). Skeletal studies, histologic examinations, evaluation deep-frozen sections anatomic preparations confirmed results CT scans. New morphologic details sinus some compartments were discovered. The these macaws consist two unpaired rostral compartments, followed caudally by eight paired compartments. Histologic examinations revealed that walls flat or cubic monolayer epithelium with underlying connective tissue. described method examination macaws, especially positioning, orientation parameters, documentation normal sinus, provides a basis for future clinical use CT.
