Cancer of the head and neck is the sixth most frequent cancer worldwide and associated with significant morbidity. The anatomy of the head and neck is very complex and knowledge of anatomy is imperative for oral and maxillofacial radiologists in order to accurately localize the tumor and its relationship to adjacent structures and to make the correct diagnosis.
Next to the development of metastases, infiltration and resultant spread of cancer into the adjacent structures are the most reliable features that differentiate malignant from benign tumors. Therefore, particularly important is the determination of tumor margins with respect to anatomic landmark structures as well as assessment of tumor spread.
The lecture will give an overview of the various routes of spread in head and neck cancers with special emphasis on imaging anatomy.
