Extended transsphenoidal approach

Abstract

Transsphenoidal surgery is well established as an effective primary treatment for tumors of the sellar region. The technique of transsphenoidal surgery has evolved over the years with many prominent surgeons contributing to its present state of refinement. The transsphenoidal approach can be modified in various ways to permit resection of parasellar tumors that otherwise would require a transcranial or transbasal operation. Our experience with these 'extended' techniques has primarily involved the transtuberculum sella approach in which bone is removed from the tuberculum sellae and the posterior portion of the planum sphenoidale. Experience with this technique continues to burgeon, and offers an excellent alternative to transcranial surgery in dealing with a difficult constellation of tumors. Meticulous attention to detail, particularly with respect to reconstruction and closure of the sellar floor, is necessary for its effective application.
