This study analyzed risk factors for postoperative cerebrospinal fluid (CSF) leak after graded multilayer cranial base repair method with dural suturing. We performed surgery via the endoscopic endonasal approach (EEA) from 2012.6 to 2018.4, and those consecutive clinical data were prospectively accumulated and retrospectively analyzed. We tailored the repair method according to the intraoperative CSF leak grade. Among 388 surgeries via the EEA, there were 10 (2.6%) cases of postoperative CSF leak after graded repair with suturing. Postoperative CSF leak occurred in two of the 150 cases without intraoperative CSF leak (grade 0), one of the 104 cases with small (grade 1) intraoperative CSF leak, two of the 60 cases with moderate (grade 2) leak, and five of the 74 cases with large (grade 3) leak. Univariate analysis indicated that chordoma (P = 0.023), estimated tumor volume ≥ 7400 mm3 (P = 0.003), and maximum tumor diameter ≥ 32.5 mm (P = 0.001) were significant risk factors for postoperative CSF leak. Additionally, among cases with intraoperative grade 3 CSF leak, chordoma (P = 0.021), estimated tumor volume ≥ 23000 mm3 (P = 0.003), and maximum tumor diameter ≥ 45.5 mm (P = 0.001) were significant risk factors for postoperative CSF leak. Maximum tumor diameter, estimated tumor volume, and chordoma tumor pathology are related to a higher risk of postoperative CSF leak.

We report the use of endoscopic endonasal surgery for dural reconstruction following a cerebrospinal fluid leak in a 33-year-old patient with recurrent meningitis since at age of 2 years. Magnetic resonance imaging showed osteolytic changes in the left temporal and sphenoid bones, including the left pterygoid plate, a few left temporal encephaloceles, and cerebrospinal fluid-like fluid in the expanded Meckel's cave and the parapharyngeal space. After endoscopic endonasal surgery, Gorham-Stout disease was diagnosed. No recurrence of cerebrospinal fluid leakage or meningitis has been observed. Thus, endoscopic endonasal surgery might improve clinical outcomes in patients with Gorham-Stout disease and skull base defects.
