Endoscopic endonasal transsphenoidal approach in the management of sellar and parasellar lesions: Alternative surgical techniques, results, complications (Part II)
The endoscopic endonasal transsphenoidal approach is a minimally invasive surgical technique for the removal of sellar and parasellar lesions. It allows panoramic vision of the surgical target and surrounding structures, with minimal trauma and a low complication rate. The procedure has been gaining in popularity in recent years. There are now surgical instruments intentionally conceived to respond to the specific characteristics of the neuroendoscopy. The widespread use of the endoscope in transsphenoidal surgery has recently contributed to the extension of the approach superior, inferior or lateral. This expansion carries significant potential for the resection of skull base lesions. For selected patients, the various techniques of the endoscopic endonasal transsphenoidal approach are valid alternatives to transcranial approaches. Macroadenomas, suprasellar or even intraventricular craniopharyngiomas, tuberculum sellae or even planum sphenoidale meningiomas and clival tumors become accessible for removal via an endoscopic approach. The authors review the main alternative surgical techniques of the endoscopic endonasal transsphenoidal approach. They also present the results and the complications of the endoscopic transsphenoidal surgery. Due to an improvement and refinement of the surgical procedures, the endoscopic endonasal transsphenoidal approach can be considered a good choice for the excision of the sellar and parasellar lesions
