© 2019 Turkish Neurosurgical Society.AIM: To investigate comparative efficacy of a novel absorbable adhesive membrane (TissuePatchDuralTM "TPD") and a fibrin glue (Tisseel "T") in reducing cerebrospinal fluid (CSF) leaks after posterior fossa and spinal procedures, and also to identify potential risk factors for CSF leakage. MATERIAL and METHODS: This is a single-center, retrospective cohort study of 123 consecutive posterior fossa (n=77) and spinal (n=46) surgeries. Patients were grouped based on dural sealants used 2-group comparison: TPD (n=56) vs. no-TPD (n=67) and 3-group comparison: T only (n=43), TPD only (n=32) vs TPD+T (n=35). RESULTS: Mean age was 38.9 ± 22.2 years (62 males, 61 females). Baseline characteristics were similar between groups. Neither 2-group (TPD: 10.4% vs no-TPD: 8.9%; p=0.778) nor 3-group (T: 9.3% vs TPD: 6.3% vs TPD+T: 14.3%; p=0.539) comparisons revealed a significant difference in postoperative CSF leakage rates. Multivariate analysis showed that diagnosis (non-tumoral vs. tumor) (OR: 5.487; 95% CI: 1.118-26.937; p=0.036); previous surgery (OR: 9.268; 95% CI: 1.911-44.958; p=0.006), postoperative hydrocephalus (OR: 5.456; 95% CI: 1.250-23.821; p=0.024) were independent predictors of postoperative CSF leakage. CONCLUSION: TissuePatchDuralTM is a novel dural sealant patch which can be safely used to reinforce dural closure in posterior fossa and spinal surgeries, and its efficacy is comparable to widely used fibrin glue (Tisseel). Non-tumoral pathologies, previous surgery, and postoperative hydrocephalus appear to be independent risk factors for postoperative CSF leakage.
