Abstract:
Objective:To evaluate the repair protocols for intraoperative cerebrospinal fluid (CSF) leaks after endoscopic endonasal clival malignancy resection (EECR) and to analyze the risk factors of surgical complication.Methods:The clinical data of patients who underwent EECR and had intraoperative CSF leaks in XuanWu Hospital, Capital Medical University between January 2012 and January 2024 were reviewed. The pathological results, imaging data, location of the dural defect, degree of intraoperative CSF leaks, repair materials, complications such as postoperative central nervous system (CNS) infections, types of antibiotics used, bacterial culture and drug sensitivity results, secondary repair, and follow-up results were collected. IBM SPSS 26 software was used to evaluate the effectiveness of the repair. Additionally, statistical analysis was conducted on perioperative complications such as CNS infections.Results:Twenty-eight patients underwent 31 EECR and 36 skull base reconstructions. There were 14 females and 14 males, aged from 4 to 70 years old, with a median of 53 years. For the repair, autologous materials such as free turbinate flap, free nasoseptal flap, pedicled nasoseptal flap, and fascia lata combined with mashed muscle were used. Initial reconstruction was successful in 26 cases, while 5 patients required a second repair, which was also successful. Postoperatively CNS infections occurred in 4 patients, and all of whom were cured. Follow-up ranged from 3 to 146 months, with no delayed CSF leak reported. The infection rate was significantly higher in patients whose first repair failed compared to those whose repair was successful (Fisher exact test, P<0.001). Conclusions:The use of different autologous materials based on the patient′s condition can effectively repair CSF leakage that occurs during EECR. Howerver, the success rate of initial repair requires improvement, as the risk of CNS infection significantly increases after a failed repair..
