Feasibilty of Trans-sphenoidal Surgery for Pituitary Tumors with Parasellar and Suprasellar Extension
Journal Title: Nepal Journal of Neuroscience - Year 2009, Vol 6, Issue 1
Abstract
Trans-sphenoidal surgery (TSS) is preferred approach for surgical management of pituitary adenoma because of its simplicity, low morbidity and mortality. However, because of narrow surgical corridor of microscopic exposure, direct visualization of cavernous sinus sometime becomes difficult leading to incomplete excision of the tumors extended into the cavernous sinus. Several modifications of this approach have been made to expand the surgical field, but despite ample experience with transsphenoidal surgery, objective data on which tumor expansion and growth pattern allows for radical adenoma resection are still sparse. It is more so in the context of our country where neurosurgical service is very limited. Therefore we tried to study the feasibility of TSS in removing pituitary tumors with extrasellar extension. We also studied the significance of tumor size and consistency in predicting extent of surgical resection of these tumors. We found that more is the extrasellar extension of tumor, more difficult it is to completely resect it as expected. Similarly, we also found that tumor size and consistency also significantly influence the extent of surgical resection.
