    Abstract:
    OBJECTIVE: This study compared the incidence of cerebrospinal fluid (CSF) leakage and residual tumors between functional and nonfunctional pituitary adenomas treated with the endoscopic endonasal transsphenoidal approach (EETA). METHODS: All patients underwent endocrine examinations and brain magnetic resonance imaging before and after surgery. The length of admission, incidence of central diabetes insipidus, incidence of CSF leakage, symptom relief, and presence of residual tumors were compared between patients with functional and nonfunctional pituitary adenomas. RESULTS: Thirty-eight patients were enrolled, among whom 12 and 26 had functional and nonfunctional pituitary adenomas, respectively. The incidence of CSF leakage was significantly higher in patients with nonfunctional adenomas; a hard or elastic tumor character accounted for the difference. A large tumor size and cavernous sinus invasion were risk factors for residual tumors. No significant differences were found in sex, length of admission, operative times, incidence of diabetes insipidus, or number of residual tumors between the two groups. The hormone levels were lower postoperatively than preoperatively in patients with nonfunctional adenomas. CONCLUSION: Nonfunctional pituitary macroadenomas resulted in more CSF leakage. Use of the rescue nasoseptal flap reduced unnecessary nasal destruction. Cooperation between a neurosurgeon and otolaryngologist was safer and more effective when using the EETA.
