Correlative study of clinical, anatomical, and pathologic aspects of supervoltage roen tgentherapy

Evaluation of treatment of malignant tumors of the maxillary sinus is difficult, being complicated by the unique and complex anatomic composition of the antrum and the infrequent occurrence of the variable tumor types. This study of 47 patients treated at The Tumor Institute of The Swedish Hospital between 1939 and 1957 has been carried out by detailed individual case analysis in an effort to correlate in each instance the clinical, anatomical, and pathologic manifestations with the therapeutic management. Such evaluation results in more definitive prognostic information than available in illdefined group studies. Anatomical considerations. The complex anatomic structure of the maxillary sinus is a major contributor to the difficulty of evaluation and management of these tumors. These completely bone-encased, pneumatic cavities are lined by epithelium, which includes mucin-secreting glandular components, and rests in apposition to the periosteum. The orbit, palate, alveolar ridge, pterygoid fossa, ethmoid and sphenoid sinuses, nasal fossa, and soft tissues of the cheek are contiguous with the bony walls. Such anatomic complexities may account
