  • Abstract
  • Look Inside

Introduction of CT and MRI has overturned the concept that the early diagnosis of malignant tumors invading the masticator space is impossible and their involvemnt is equated with inoperability and noncurability. We experienced 12 patients with cancer in the space in the recent 5 years. Among them two cases of tumor de novo and a case in-volved by metastasis were presented. Nine other tumors were directly extended from other regions. Despite of no early signs or symptoms, maligna-ncies of the masticator space are characterized clinically by trismus and pain. Tumor extending from the oral cavity or tonsil elicited trismus earlier than others.
