  • Look Inside

The reports of the skull base reconstruction surgeries have been recently increasing accom-panied with expanded excisions of head and neck malignancies. However, the technical security has not been completely established yet, and the indica-tions of operation has been discussed for each case.

We experienced one case with nasal septal chon-drosarcoma. The mass of this case deeply ex-panded into the intracranial space and the prognosis was diagnosed unfavorable without radical opera-tion because this tumor is low malignancy but resistant to radiotherapy and chemotherapy. Skull base was excised with full thickness bidirectionally from the nasopharynx and intracranially. The defect of the skull base was 4×5cm in large and was reconstructed with a pericranial flap, free skin graft beneath it and an outer table of parietal calvarium. At 6 months after the operation the reconstructed skull base steady and the general condition was favorable.
