The masticator space

Pictorial Review


The posterior displacement of parapharyngeal fat differentiates tumors that originate in the masticator space (MS) from those originating in surrounding spaces. Most benign tumors originating in the MS are hemangiomas, lymphangiomas, osteoblastomas, or schwannomas. Malignant tumors include chondrosarcomas, osteosarcomas, malignant schwannomas, non-Hodgkin lymphomas, rabdomyosarcomas, mandibular metastases, and so on. If a tumor is suspected to have originated in the MS, we should consider the possibility of malignancy.
