Clinical characteristics and surgical outcomes between traumatic and nontraumatic cerebrospinal fluid rhinorrhea

Multifocal defects and meningitis were more prevalent in traumatic CSF rhinorrhea patients, leading to increased complexity in treatment management. Iatrogenic rather than accidental traumatic CSF rhinorrhea is an independent risk factor for development of meningitis. The endoscopic combined coronal extradural approach, in conjunction with various vascularized flaps, can effectively supplement skull base reconstruction, especially for complex traumatic CSF rhinorrhea.
