 In order to apply pantomography to radiological diagnosis of the maxillary lesions it is very important not only to know roentgenographic anatomy but also to know value limitation of pantomography.

 Lead foils and lines are attached to anatomic landmarks of the dry maxillozygoma specimen and x-ray pictures are taken with Panex, Morita Co., Ltd.

 On the pantomogram the medial border of the maxillary sinus is composed of the angle of anterior and medial walls. The lateral border is composed of maximum convexity of the posterior wall.

 The anterior, posterior and medial walls are recognized as anatomical landmarks only when these walls are covered by radiopaque material. Most of the anterior and posterior walls in these pictures are superimposed to the medial wall. The anterior wall will appears to occupy medial two thirds of the maxillary sinus and the posterior wall occupies lateral third.

 The anterior, posterior and medial walls of the sinus cavity do not appear as definite landmarks on the pantomogram. Moreover, the individual wall is superimposed to each other. Therefore, careful interpretation of the pantomogram is highly essential, for assessment of the maxillary bone destruction.
