Success Rate and Complications of Cerebrospinal Fluid Rhinorrhea Treated with a Transcranial Approach

The aim of this study was to evaluate the clinical outcomes of cerebrospinal fluid (CSF) rhinorrhea in patients treated with transcranial surgery. Here, we retrospectively reviewed 23 patients with CSF rhinorrhea between 2008 and 2015 at our university hospital. Nine (39.1%) patients were treated conservatively, whereas 12 (52.2%) patients were treated with a transcranial approach. Our results showed that 7 (30.4%), 11 (47.8%), and 5 (21.7%) patients had spontaneous, traumatic, and iatrogenic CSF leakage, respectively. In our study, the cribriform plate was the most common site of leakage, and it was found to be involved in 5 (21.7%) patients. The mean diameter defect of the fistula was 130.40 ± 190.47 mm2 and there was no significant difference between this defect and the different etiology types. In our study, meningitis, third nerve palsy, and vasospasm were the main complications that arose during the treatment of CSF rhinorrhea. Moreover, 6 (26.1%) of 7 (30.4%) patients had spontaneous CSF leaks that were treated with surgery. Notably, spontaneous CSF leaks did not stop when treated with conservative measures. In addition, there were no significant differences between etiology types and CSF leaks. The primary surgical repair rate was 78.3% and the secondary surgery repair rate was 91.6%. Importantly, as we preferred using this type of transcranial surgery in our clinic, there has been a higher success rate with endoscopic treatments and fewer major complications from CSF rhinorrhea in the literature.
