Posteromedially, at the level of the hard palate (the superior aspect of the buccal space), the superficial layer of the deep cervical fascia (SLDCF) extending between the masseter and the buccinator muscle is incomplete, allowing spread of pathology between the buccal space and the masticator space. • • • Masseter and pterygoids Temporalis. The differential diagnosis of a masticator space (MS) lesion is broad, owing in part to the multiple structures contained within such a small region. Each space is delineated by a superficial layer of the deep cervical fascia (SLDCF). The masticator space is a deep facial space that is outlined by the superficial layer of the deep cervical fascia and lies laterally and evenly in front of the prestyloid space, medial to the pharyngeal space and beneath the skull base. When they do occur, they can be either benign or malignant, such as vasculogenic tumors, lipomas, neurogenic tumors (e.g., Submasseteric abscesses are rare and are associated with marked trismus. CT has been the main imaging method for diagnosing lesions in the masticator space and adjacent to the mandible; however, we found that, in some of our cases, CT defined the lesion poorly or not at all. 1). It lies inferiorly to the temporal space and is anterolateral to the parapharyngeal space. Medial wall of the parapharyngeal space is the lateral wall of the peritonsillar space. 6 Perivertebral space (anterior portion). Floor of the Mouth, Sublingual and Submandibular Space: Imaging . As defined with anatomic criteria, the masticator space (anatomic masticator space) is a deep facial space delineated by a splitting of the deep cervical fascia that encloses the four muscles of mastication: the medial and lateral pterygoid muscles, the masseter muscle, and the temporalis muscle. 7 Retropharyngeal space (virtual at this level). Contrast enhanced CT 1 Parapharyngeal space.
