Lead wires and 76% Urografin are attached to the dry skull specimen and the normal anatomic landmarks of maxillary sinus can be effectively demonstrated on the panex EM.
Distortions of the pantomogram on the anterior wall of maxillary sinus are 9° deviation, 30% reduction, horizontal and 3°deviation, 16% prolongation, vertical. The so-called posterior wall of the maxillary sinus was cleary outlined on the panoramic view, but composed of the posterior, lateral, and interior wall. Therefore, the so-called posterior wall is properly named the lateral-posterior region and lateral-posterior line. The Anterior wall is recognized as anatomic landmarks, but the posterior, lateral and interior wall are recognized only when these wall are covered by radiopaque markers.
The median wall is composed of the anterior region of median wall and anterior wall, so the median wall is properly named the interior Region and the interior line.
Therefore, careful interpretation of the pantomogram is highly essential for the diagnosis of maxillary sinus.
