Solitary Fibrous Tumors (SFTs) are an uncommon mesenchymal neoplasm, mainly treated by surgical resection. A complete resection is important, but it may be difficult to secure sufficient margins with preserved functionality and esthetics in the head and neck region. We report a rare case of SFT occupying the temporal and infratemporal fossa. A 36-year-old woman presented with a tumor in the right temporal and infratemporal fossa. A core needle biopsy was performed; histopathological examination led to a diagnosis of SFT. We resected the tumor with a hemifacial dismasking flap and a zygomatic approach; reconstruction was performed using a free anterolateral thigh flap. The resected tumor revealed negative surgical margins on histopathology, with no recurrence at 1 year postoperatively. A facial dismasking flap is useful for approaching deep face areas, such as the infratemporal fossa or skull base. Moreover, the upper two-thirds of the face can be unfolded without any noticeable facial wounds, and the facial nerve can be preserved. Because the visual field could be secured only by temporary zygomatic arch transection and mandible coronoid process transection, we selected a zygomatic approach. We considered the facial dismasking flap and zygomatic approach as useful given the tumor localization and postoperative esthetic outcome in this case
