A case report of a traumatic cerebrospinal rhinorrhea patient with sphenoid sinus bone defect

Cerebrospinal fluid (CSF) rhinorrhea is a result of communication between subarachnoid space and sinonasal mucosa through skull base defects. The presence of skull base defect can increase the risk of meningitis, thus in most cases of consistent CSF rhinorrhea, surgery is needed to repair the defect and prevent further complications. The surgical approach can be determined by the location of skull base defect. Here, we present a case of CSF leak in a 34-year-old female with defect of lateral recess of left sphenoid sinus that present as watery rhinorrhea. We repaired the skull base defect by endoscopic transnasal transpterygoidal approach with multi-layered grafts. There was no recurrence or complications during the 12 months after surgery.
