In recent years, resections of midline skull base tumors have been conducted
using endoscopic endonasal skull base (EESB) approaches. Nevertheless, many
surgeons reported that cerebrospinal fluid (CSF) leakage is still a major
complication of these approaches. Here, we report the results of our 42 EESB
surgeries and discuss the advantages and limits of this approach for resecting
various types of tumors, and also report our technique to overcome CSF leakage.
All 42 cases involved midline skull base tumors resected using the EESB
technique. Dural incisions were closed using nasoseptal flaps and fascia patch
inlay sutures. Total removal of the tumor was accomplished in seven pituitary
adenomas (33.3%), five craniopharyngiomas (62.5%), five tuberculum sellae
meningiomas (83.3%), three clival chordomas (100%), and one suprasellar
ependymoma. Residual regions included the cavernous sinus, the outside of the
intracranial part of the internal carotid artery, the lower lateral part of the
posterior clivus, and the posterior pituitary stalk. Overall incidence of CSF
leakage was 7.1%. Even though the versatility of the approach is limited, EESB
surgery has many advantages compared to the transcranial approach for managing
mid-line skull base lesions. To avoid CSF leakage, surgeons should have skills
and techniques for complete closure, including use of the nasoseptal flap and
fascia patch inlay techniques.
