Couldwell, William T. | Intracranial hypotension in the setting of concurrent perineural cyst rupture and subarachnoid hemorrhage | Although most patients with intracranial hypotension typically present with headaches, the rest of the clinical spectrum is characteristically non-specific and often quite variable. In a patient with concurrent pathologies that can produce a similar clinical picture, a high index of suspicion must b... | | 2013-01-01 |

Couldwell, William T.; Orlandi, Richard R.; Jensen, Randy L. | Endoscopic-assisted craniofacial resection of esthesioneuroblastoma: minimizing facial incisions | The 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 invasive | 2003 |
