Objective This study was aimed to compare comparative efficacy of transsphenoidal endonasal endoscopic and microscopic pituitary surgery at single center of a developing country. Methods This study included 198 patients in which 50 patients were studied prospectively and 148 patients were studied retrospectively, diagnosed with pituitary adenoma who presented to neurosurgery department at Sawai Man Singh hospital in Jaipur, India, and were operated via transsphenoidal route between 2013 and 2018. Patients' records were reviewed and relevant clinical and surgical data were collected. Patients were divided into two groups based on the surgical procedure performed, endoscopic endonasal transsphenoid approach (group 1) and microscopic transsphenoidal approach (group 2). Outcomes, in terms of efficacy and the resulting complications of each procedure were compared and analyzed. Results A total of 198 patients with pituitary adenoma were operated during the study period. Among them, 119 (60.1%) patients were operated by endoscopic and 79 (39.9%) patients were operated by microscopic transsphenoidal approach. In endoscopic group, intraoperative cerebrospinal fluid (CSF) leak was present in 39 patients (32.77%) and 23 (29.11%) in microscopic group. Complete tumor removal was achieved in 69.75% in endoscopic and 48.13% in microscopic group ( p = 0.004). Endocrine control was achieved in 78.94% (30 out of 38) in endoscopic and 68.18% (15 out of 22 patients) in microscopic group. Conclusion The transsphenoidal approaches for resection of pituitary adenoma, both endoscopic and microscopic approach, are minimally invasive and effective for disease control. Both the approaches lead to similar endocrine control, visual symptoms, complications, and long-term outcome. Therefore, the selection of the final approach should be individualized, ultimately depending on the surgeons' comfort, experience, and familiarity with the particular technique.
