Posttraumatic cerebrospinal fluid (CSF) leakage frequently complicates skull base fractures. While most CSF leaks will cease without treatment, patients with persistent CSF leaks may be at increased risk for meningitis, and many will require surgical intervention. We reviewed the medical records of 51 patients treated between 1984 and 1998, with CSF leaks that persisted for 24 hours or longer after head trauma. Twenty-eight patients (53%) had spontaneous resolution of the leakage at an average of 5 days. Twenty-three patients (47%) required surgery. Eight patients (16%) had occult leaks presenting with recurrent meningitis at an average of 6.5 years posttrauma. Forty-three (84%) patients with CSF leaks had an associated skull fracture, most commonly involving the frontal sinus, while only 18 patients (35%) had parenchymal brain injury or extra-axial hematoma. Eight patients (16%) had delayed leaks at an average of 13 days posttrauma. Among patients with clinically evident CSF leakage the frequency of meningitis was 10% with antibiotic prophylaxis, and 21% without antibiotic prophylaxis. Thus, prophylactic antibiotic administration halved risk of meningitis. A variety of surgical approaches was used, with minimal morbidity. Three of 23 surgically treated patients (13%) required additional surgery for continued leakage. Patients with CSF leaks that persist greater than 24 hours are at risk for meningitis, and many will require surgical intervention. Prophylactic antibiotics may be effective and should be considered in this group of patients. Patients with skull fractures involving the skull base or frontal sinus should be followed for delayed leakage. Surgical outcome is excellent.
