BACKGROUND: The emerging endoscopic endonasal transsphenoidal approach for pituitary adenomas is safe and effective. An intraoperative sellar floor reconstructive method after this approach is challenging.[nl] OBJECTIVE: To describe a simple method of sellar reconstruction after endoscopic endonasal transsphenoidal surgery for pituitary adenomas by nasal turbinate tissue.[nl] MATERIALS AND METHODS: Thirty patients with defects in the floor of the sella turcica, after endoscopic endonasal transsphenoidal surgery for pituitary adenomas, underwent reconstruction with nasal turbinate tissue. The surgical technique is described.[nl] RESULTS: Patients who underwent this sellar reconstruction did not show postoperative cerebrospinal leak or other complications.[nl] CONCLUSION: Nasal turbinate tissue is an excellent source of donor material for successful reconstruction of the sellar floor. It is costless, safe, soft, malleable and easy to obtain in the same field of surgery with suitable size without inducing side effects or complications.
