title: A classification system for maxillary sinus carcinoma.
abstract: A system of classification that reflects the site of origin within the sinus cavity is proposed for maxillary sinus carcinoma. Careful examination for areas of anesthesia or pain over the distribution of the various branches of the infraorbital nerve may localize the site of origin of the disease within the maxillary sinus. Early treatment can thus be provided, sometimes before the tumor can be identified radiologically.
