Aim: The aim of this study was to compare the efficacy of endoscopic versus microscopic excision of pituitary adenoma, and to evaluate the merits and demerits of each approach. Materials and Methods: Prospective data were collected and patients were surgically treated for pituitary adenoma at SMS Hospital, Jaipur, Rajasthan, India. Patients consent was obtained. Age, sex, presenting symptoms, length of hospital stay, pre- and post-operative hormone status, extent of resections of tumors, and intra- and post-operative complication were noted. Results: A total of thirty patients with pituitary adenoma were operated transsphenoidally. Seventeen patients were operated by endonasal endoscopic transsphenoidal surgery and 13 patients were operated by microscopic transsphenoidal surgery. In an endoscopic group, complete tumor excision was achieved in 11 (64.71%) patients, and in microscopic group, it was achieved in 6 (46.15%) patients. In endoscopic group, mean operative time was 111.29 ± 21.95 min (ranged 80–135 min), and in microscopic group, it was 134.38 ± 8.33 min (ranged 120–145 min). In endoscopic group, mean blood loss was 124.41 ± 39.64 ml (60–190 ml), and in microscopic group, it was 174.62 ± 37.99 (100–220 ml). Postoperative sinusitis was present in 1 (5.88%) patient in endoscopic group and in 2 (15.38%) patients in microscopic group. Conclusion: Endoscopic approach provides a wide surgical field and broad lateral vision making easier distinction of tumor tissues. Thus, there is less blood loss, greater extent of tumor removal and it had less operative time, less postoperative complication, and early discharge from the hospital.
