How to Perform Subfronto-Orbitonasal Approach for Anterior Cranial Base Surgery

摘要: Subfrontal approaches were first proposed and described by Horsley Cushing in the early beginning of neurosurgery. These mostly bifrontal flaps for skull base surgery. First combined craniofacial Dandy [1] 1941 Ray McLean [6] 1943 orbital tumors removal. Principles transcranial transfacial surgery then precised Smith et al. [8], Ketcham [3] Derome [2]. Later, enlarged with mobilization rims nasal pyramid proposed. Subfronto-orbito-nasal (SFON) approach was 1978 Raveh as “anterior extended subcranial approach” anterior fractures [4, 5]. He indications 1980 benign malignant tumor resection This allows performing a mediofrontonasal monobloc flap including rims. We used it removal ethmoidal such adenocarcinomas but we rapidly discovered large field vision given this cranial fossa, ethmoidal, sphenoidal maxillary sinuses, internal part orbit clivus well [7].
