201 Couldwell, William T.; Orlandi, Richard R.; Jensen, Randy L.Endoscopic-assisted craniofacial resection of esthesioneuroblastoma: minimizing facial incisionsThe surgical management of esthesioneuroblastomas has traditionally been craniofacial resection, which combines a bifrontal craniotomy with a transfacial approach. The latter usually involves a disfiguring facial incision, mid-facial degloving, lateral rhinotomy, and/or extensive facial osteotomies...Esthesioneuroblastoma; Craniofacial resection; Endoscope; Craniofacial surgery; Minimally invasive2003
