Anterior skullbase surgery with transbasal approach via frontal craniotomy has been performed in fifteen cases. Eleven patients underwent combined transbasal and transfacia procedure. Eleven cases were the malignant tumors of paranasal sinuses and nasal cavity.Galeopericranial flap were used for the reconstruction of the anterior skull base. The patients in this series suffered no major complications such as CSF leak, meningitis, flap necrosis. The patients who underwent combined procedure and were widely resected of facial and nasal bone structure had minor deformation of feature and nasal dysfunction. On the other hand four patients who underwent transbasal procedure alone could be remained the normal nasal function and feature. We can get the good access to the nasal cavity by transbasal approach rather than by transfacial approach, and we can extend the operation field further more with osteotomy of supraorbital bar. The transbasal approach is the first choice of procedure for en bloc resection of tumor of the paranasal sinuses and nasal cavity invading to the anterior cranial fossa.
