Repair of the sella turcica during endonasal endoscopic transsphenoidal surgery

Objective To describe techniques and clinical effects used in repair of the sella turcica during(endoscopic) endonasal transsphenoidal surgery for sellar region lesions.Methods Two hundred and thirty-five patients with defects in the floor of the sella turcica,after endoscopic endonasal transsphenoidal surgery,underwent repair with biomaterial and autologous tissues.Different techniques of sellar reconstruction and indications for each specific condition were reviewed in a series of the consecutive patients.Results All patients in our group were considered the candidates for sellar reconstruction after the endoscopic operation,mainly because of intraoperative sellar floor open or cerebrospinal fluid leaks.Patients who underwent the sellar repair and lumbar subarachnoid cavity drainage did not show postoperative cerebrospinal leak or other complications permanently.Conclusion Repair of the sellar floor is considered necessary in the patients who underwent operations via the endoscopic transsphenoidal approach.It is important to select suitable materials for successful reconstruction of the sellar floor.
