Achieving a watertight dural closure is always important. It is even more important in the case of skull-base procedures where transsphenoidal, extended transsphenoidal, and translabrynthine approaches are used. When the arachnoid is opened the requirement to achieve closure is essential. Failure to achieve closure may lead to meningitis and other serious sequellae.
Skull base surgery has traditionally involved large transcranial, transsphenoidal, or transfacial approaches with a relatively high morbidity. The endonasal, endoscopic approach to the midline skull base decreases morbidity, increases visualization, and increases patient comfort. Other benefits of this type of approach include: |
