These discrepancies may be attributed to different series with different criteria for remission and variable follow-up durations. Additional data from experienced centers may address these discrepancies. In this study, we present the results obtained from 96 endoscopic transsphenoidal surgeries (ETSSs) for CD conducted in a well-experienced center.Methods : Pre- and postoperative data of 96 ETSS in 87 patients with CD were included. All cases were handled by the same neurosurgical team between 2014 and 2022. We obtained data on remission status 3\u22126 months postoperatively (medium-term) and during the latest follow-up (long-term). Additionally, magnetic resonance imaging (MRI) and pathology results were obtained for each case.Results : The mean follow-up duration was 39.5\u00b13.2 months. Medium and long-term remission rates were 77% and 82%, respectively. When only first-time operations were considered, the medium- and long-term remission rates were 78% and 82%, respectively. The recurrence rate in this series was 2.5%. Patients who showed remission between 3\u22126 months had higher longterm remission rates than did those without initial remission. Tumors &gt;2 cm and extended tumor invasion of the cavernous sinus (Knosp 4) were associated with lower postoperative remission rates.Conclusion : Adenoma size and the presence\/absence of cavernous sinus invasion on preopera-tive MRI may predict long-term postoperative remission. A tumor size of 2 cm may be a supporting criterion for predicting remission in Knosp 4 tumors. Further studies with larger patient populations are necessary to support this finding.<\/jats:p>","DOI":"10.3340\/jkns.2023.0100","type":"journal-article","created":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T05:04:36Z","timestamp":1709183076000},"page":"237-248","update-policy":"https:\/\/doi.org\/10.3340\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Medium
