The primary objective is to demonstrate superiority of TachoSil® compared to current practice as an adjunct in sealing the dura mater. The efficacy of the dura mater sealing must be evaluated post-operatively. The secondary objective is to evaluate the safety of TachoSil® as an adjunct in sealing the dura mater.
The trial population will consist of 726 randomised (1:1) patients elected for skull base surgery. The trial duration consists of screening, surgery, efficacy follow-up after 7±1 weeks and safety follow-up 28±2 weeks after surgery.

Primary suture must be performed. Duraplasty may be performed at the discretion of the investigator. TachoSil® must be applied under aseptic conditions during the closure of the dura.
|Active Comparator: Current practice group||
Procedure: Current Practice
Primary suture must be performed. Duraplasty may be performed at the discretion of the investigator.
In addition to primary suture, whatever means of dura closure deemed necessary by the investigator may be used with the exception of TachoSil®.
- Percentage of Participants With Clinically Evident Verified Post-Operative Cerebrospinal Fluid Leak or Clinically Evident Pseudomeningocele or Treatment Failure [ Time Frame: Up to 8 Weeks (7 Weeks ± 1 Week) ]An assessment was performed daily from randomization to Day of Discharge and at the Efficacy Follow-up visit at week 7 ± 1 week. Clinically evident cerebrospinal fluid leak was confirmed by: 1. Glucose concentration test and/or 2. β-2-transferrin test. A clinically evident pseudomeningocele was considered to be present post-operatively if the following criteria were fulfilled: 1. A subcutaneous, visible/palpable fluctuant fluid accumulation was noted at the site of the surgical incision or adjacent to it; 2. It is suspected the fluid accumulation is cerebrospinal fluid. A treatment failure was defined as application of a new and/or different treatment after application of the study treatment or a third application of (or part of) the selected study treatment on the outside of the dura.
- Percentage of Participants With Post-Surgical Non-Clinically Evident Post-Operative Pseudomeningocele [ Time Frame: Assessment at least once prior to discharge from neurosurgical ward, with the expected discharge from neurosurgical ward after an average of 10 days (Up to 28 Weeks) ]Non-clinically evident pseudomeningocele was defined as a cerebrospinal fluid accumulation found on a postoperative computerized tomography (CT) or magnetic resonance imaging (MRI) scan which fulfilled the following criteria according to the radiologist assessment before Day of Discharge: CT Scan-Fluid accumulation seen as Hypodense signal, MRI Scan-Fluid accumulation seen as Hypointense signal in T1-weighted image and/ OR Fluid accumulation seen as Hyperintense signal in T2-weighted image.
