ABSTRACT
BACKGROUND AND OBJECTIVES: The classic craniofacial resection for anterior skull base tumor uses bifrontal craniotomies together with lateral rhinotomies. This approach requires frontal lobe retraction and may be associated with the development of brain edema and encephalomalacia. The subfrontal approach by use of supraorbital-frontal bone osteotomy permits removal of anterior skull base lesions with minimal retraction of frontal lobe and provides excellent exposure by reducing the depth and obliquity of the approaches and lowering the inferior visual angle. MATERIALS AND METHODS: We reviewed 3 cases of anterior skull base tumor involving the frontal, sphenoid sinus and partially clivus, or frontal lobe. They were 1 female patient and 2 male patients aging from 56 to 64. RESULTS: We obtained sound results, both functionally and cosmetically, except for one who died of brain metastasis. CONCLUSION: The craniofacial resection with subfrontal approach using supraorbital-frontal bone osteotomy provides excellent exposure, particularly in high grade malignancy of the anterior skull base, and can reduce postoperative morbidities.
