Show morePurpose: Endoscopic transsphenoidal surgery causes nasal morbidity and negatively affects health-related quality of life (HRQoL). Knowledge on actionable symptoms that could improve postoperative HRQoL is therefore important. This study assessed the impact of nasal symptoms on postoperative HRQoL. Methods: This perioperative cohort study included 103 adult patients undergoing endoscopic pituitary adenoma resection (August 2016-December 2018), with measurements preoperatively, and 5 days, 6 weeks and 6 months after surgery. Nasal symptoms were measured with the Anterior Skull base nasal inventory-12, and HRQoL with the Short Form-36 (SF-36) physical (PCS) and mental component scores (MCS). Linear regression analysis was used to assess (1) determinants of postoperative nasal morbidity, (2) associations between number of symptoms or (3) individual symptoms and HRQoL, and (4) the percentage of variance of HRQoL explained by nasal symptoms. Results: The number of nasal symptoms transiently increased after surgery. No significant treatment- or disease-related determinants of nasal morbidity were identified. The number of nasal symptoms was significantly associated with a lower PCS (beta = - 1.0; 95%CI - 1.5, - 0.4), but not with MCS at 6 weeks. Similar results were observed at 6 months. Headaches (42.2%), problems with smell (42.0%), and taste (36.0%) were the most prevalent symptoms, while sense of smell and taste, and nasal discharge showed the strongest associations with HRQoL. Conclusions: Postoperative nasal symptoms, in particular problems with smell and taste, significantly affect pituitary patients' physical HRQoL. Monitoring of these symptoms may aid in determining which patients may benefit from intensified follow-up and treatment, aiming to optimize HRQoL. Show less

Show moreObjective The extended endoscopic approach provides unimpaired visualization and direct access to ventral skull base pathology, but is associated with cerebrospinal fluid (CSF) leak in up to 25% of patients. To evaluate the impact of improved surgical techniques and devices to better repair skull base defects, we assessed published surgical outcomes of the extended endoscopic endonasal approach in the last two decades for a well-defined homogenous group of tuberculum sellae and olfactory groove meningioma patients. Methods Random-effects meta-analyses were performed for studies published between 2004 (first publications) and April 2020. We evaluated CSF leak as primary outcome. Secondary outcomes were gross total resection, improvement in visual outcomes in those presenting with a deficit, intraoperative arterial injury, and 30-day mortality. For the main analyses, publications were pragmatically grouped based on publication year in three categories: 2004-2010, 2011-2015, and 2016-2020. Results We included 29 studies describing 540 patients with tuberculum sellae and 115 with olfactory groove meningioma. The percentage patients with CSF leak dropped over time from 22% (95% CI: 6-43%) in studies published between 2004 and 2010, to 16% (95% CI: 11-23%) between 2011 and 2015, and 4% (95% CI: 1-9%) between 2016 and 2020. Outcomes of gross total resection, visual improvement, intraoperative arterial injury, and 30-day mortality remained stable over time Conclusions We report a noticeable decrease in CSF leak over time, which might be attributed to the development and improvement of new closure techniques (e.g., Hadad-Bassagasteguy flap, and gasket seal), refined multilayer repair protocols, and lumbar drain usage.

Show moreEndoscopic transsphenoidal surgery for pituitary adenomas is a safe and highly effective first-line treatment that is well tolerated by patients. There are many potential complications, and there is a large variation in complexity of surgery. This article presents the philosophy, surgical techniques, and outcomes of a high-volume pituitary adenoma center. Three surgical videos illustrate some procedures. The experience has reinforced the authors' belief that experience and surgical volume are key to high quality of care. Show less
