[Anatomy and normal variations of paranasal sinuses in radiological imaging]. / Anatomie und Normvarianten der Nasennebenhöhlen in der Schnittbildgebung.

ABSTRACT

CT and MRI are the radiological methods of choice in the diagnostics of diseases of the paranasal sinuses. Detailed anatomical knowledge is mandatory for correct image interpretation. Before endonasal surgery the individually variable anatomic situation has to be known. This article describes radiologically relevant anatomical structures and summarizes normal variations.
