The usefulness of the infratemporal fossa type C approach is reported through a presentation of a case of clival chordoma, which was successfully treated by this approach. Although it is complicated and includes some demerits, this approach gives a shorter and wider access to mid-skull base pathology than other approaches. Among the demerits, deformity of the temporal region caused by extensive drilling of the bone could be minimized by cosmetic mastoidectomy, which was first applied during this approach by the authors. The surgical anatomy for this approach is demonstrated using a cadaver specimen.

Background/aim: Neurofibromatosis type 1 (NF1) is an autosomal dominant tumor predisposition syndrome that is also characterized by skeletal abnormalities. In the cranial region, skeletal dysplasia is observed that is associated with a characteristic peripheral nerve sheath tumor, the plexiform neurofibroma (PNF). The aim of the study was to determine PNF-associated skeletal asymmetries of the mid-skull and skull base as an indicator of local tumor development.

We report a patient who underwent secondary reconstruction for facial paralysis involving 2 regions of augmentation and 3 facial reanimations using a neurovascular latissimus dorsi (LD) chimeric flap.A 53-year-old man underwent mid-skull base surgery for a chondrosarcoma at the temporomandibular joint and primary reconstruction using a free anterolateral thigh flap. At 28 months after surgery, he showed temporal and buccal depression and incomplete facial paralysis.
