The aim of the study is to discuss the current management options for intra- and extra-cranial communication giant cell tumor of the lateral skull base and perform a review of the literature. A total of 6 patients with giant cell tumor of the lateral skull base were retrospectively enrolled in the study. The principal complaints, imaging manifestations, surgical resection and reconstruction of intra- and extra-cranial communication defects for the diseases were discussed. There were 2 males and 4 females. The most of principal complaints were discomfort or pain in the temporomandibular joint in 5 cases (83.3%). Imaging examination showed invasion of the temporal bone alone in 3 cases (50.0%) and both temporal bone and sphenoid bone involvement in 3 cases (50.0%). C-shaped preauricular infratemporal fossa approach was used for tumour removal and gross total resection was done in all 6 cases. The pedicled temporal muscle fascial flap was used to reconstruct the intra- and extra-cranial communication defect of the lateral skull base. The conclusion is that giant cell tumor is a benign tumor but is also locally aggressive. Gross total resection is the most commonly recommended treatment choice for giant cell tumor of the skull and can achieve good treatment outcomes. The temporalis muscle flap is a good alternative choice for reconstruction of the defect.
