3D-Volume Rendering of tomography study reconstruction. (a) Anterolateral view with image of soft tissue, a transspatial tumor is demonstrated in the right subtemporal region with extension to the zygomatic and pterygomaxillary fossae, deep in the masseter muscle. (b) Anteroinferior view with bone image: Facial asymmetry is demonstrated with increased width of the zygomatic fossa, anterior displacement, and thinning of the right zygomatic process. As with remodeling of the mandibular ramus, there is no alteration of the cortical bone.

Magnetic resonance studies were evaluated where, when a considerable extension of the lesion is observed, from the zygomatic fossa to the pterygomaxillary, with displacement of the masseter muscle [Figure 1].

The first procedure involved a suprazygomatic incision where a biopsy was taken for histopathological study and ablation of the suprazygomatic portion of the lesion was realized [Figure 2].
