Abstract
Objective: 1) Report our experience in surgical treatment for closure of CSF fistulas of different etiologies, with a new endoscopic technique without invasive surgery. 2) Improve the treatment of CSF leakage, thus avoiding craniotomy and its sequelae.
Method: We present 5 cases of adult patients with CSF fistula treated by endoscopic surgery from July to December 2011 using cartilage and mucoperichondrium tragal graft, resorbable thread as a guide and sterile sponge, previus revivig edges. Overlay technique was used and nasal packing was for 5 days. Endoscopic controls were carried out.
Results: In all surgery cases closure of the fistula was observed at 6 weeks. There were no recurrences and no reoperationes were necessary. All patients improved their symptoms without reoccurring liquorrhea.
Conclusion: Endoscopic closure of CSF fistulas with the technique of cartilage graft has proved a very safe method for this type of defect in the skull base as well as being reliable, secure, and free of sequelae known as craniotomies.
