Transsphenoidal Approach for Pituitary Adenomas in Elderly Patients.

With a rapidly expanding elderly population in the United States, the incidence of pituitary adenomas in elderly will continue to rise. In this study, we aim to evaluate the safety and efficacy of transsphenoidal endoscopic endonasal resection for pituitary adenomas in the elderly population. A retrospective review of 131 consecutive patients who underwent transsphenoidal endoscopic endonasal resection for pituitary adenomas at the University of Miami Hospital between 2012 and 2016 was performed. Preoperative, intraoperative, and surgical outcomes were analyzed in elderly (>70 years) versus nonelderly (<70 years) patients. Of the 131 patients, 23 of them were >70 years (18%), of which 14 were septuagenarians and 9 were octogenarians. Elderly patients were more likely to present with vision loss (80.8% vs. 56.6%; P = 0.013) and larger tumors on imaging (2.7 ± 1.0 cm vs. 2.4 ± 1.3 cm; P = 0.042). Overall surgical and endocrinologic outcomes between the 2 groups were similar. However, patients <70 years old were more likely to have a gross total resection (86.7% vs. 65.4%; P = 0.011), as well as transient diabetes insipidus (54.3% vs. 26.9% P = 0.012) and intraoperative cerebrospinal fluid leak (83.5% vs. 58.5%; P = 0.013). However, permanent postoperative complication rates were similar including rate of permanent diabetes insipidus (4.3% elderly vs. 12.1% adult), cerebrospinal fluid leak (8.7% elderly vs. 8.4% adult), and meningitis (4.3% elderly vs. 2.8% adult). There were no medical complications or deaths in our cohort. The transsphenoidal endoscopic endonasal approach can be a safe and effective technique for resection of pituitary adenomas in patients >70 years old with appropriate patient selection.
