[Transnasal-sphenoided endosurgical and microsurgical technique of pituitary adenometomies].

ABSTRACT

OBJECTIVE: To evaluate the surgical technique of pituitary adenomas by naso-sphenoid way and the prevention of complication. METHOD: The pituitary adenomas in 19 cases were removed under endoscope and microscope by the transnasosphenoided way. Sphenoid-saddle base was restructed with lip-tendon-membrane and the nasal separate bone. RESULT: Seventeen cases had entire resection in the 19 patients. Two cases had subtotal resection. The symptoms were improved with no sever complications in 19 cases during the period of 3-36 months follow-up and no recovery in 17 cases. CONCLUSION: lt is a effective surgical technique that the pituitary neoplasms are removed by nasosphenoidal way under the endoscope and microscope with the alcohol for preventing the tumor recovery and with the lip-tendon-membrane and nasal separate bone for restructing the saddle base.
