Practical Tips to Perform the Subcranial Approach

• Admit the patient to an intensive care unit for 24 h after surgery. Introduction The concept of a broad subcranial approach to the entire anterior skull base was first introduced as an alternative to the traditional craniofacial approach. The subcranial approach has several major advantages. (1) It affords a broad exposure of the anterior skull base from below rather than through the transfrontal route. (2) It provides an excellent access to the medial orbital walls and to the sphenoethmoidal, nasal and paranasal cavities. (3) It allows simultaneous intradural and extradural tumor removal and safe reconstruction of dural defects. (4) It does not require facial incisions. (5) It is performed with minimal frontal lobe manipulation.
