[X-ray anatomy of the maxillary sinuses]

In a complex roentgenological investigation of 12 anatomical preparations of the cranium and of 100 isolated maxillary bones (including multiplane roentgenography and the artificial contrasting of the antrum of Highmore) it has been established that in adult people the maxillary sinuses have as a rule, a shape of an irregular truncated pyramid (96%), rarely - a rounded shape. The standard roentgenograms of the cranium can reveal comparatively small portions of osseous walls of the maxillary sinuses. Special spot-films are necessary for studying the sinus walls on their full length.
