ABSTRACT: Objective: This retrospective study aims to survey the clinical outcomes of 341 consecutive patients surgically treated for and diagnosed with craniopharyngioma (CP) treated in a 10-year period in a single institution. Methods: The clinical reports of three hundred forty-one patients CP patients treated surgically between January 2006 and December 2016 were reviewed and analyzed retrospectively. Results: Our cohort consisted of 341 patients (202 male, 139 female) with a mean age of 34.9 years (range 1 - 74 years); Tumor Features: 129 patients (37.8%) had cystic tumors, 88 (23.8%) had solid tumors whereas 126 (36.4%) had heterogeneous lesions with a solid and cystic portion; calcifications were present in 139 (40.8%); Tumor Topography: Suprasellar 198 (58.1%), Intrasellar 40 (11.7%), Intra-third ventricular 103 (30.2%); Surgical approaches used among the patients included: Pterional 262 (76.8%), Transsphenoidal (TS) 42 (12.3%) Transcallosal 20 (5.9%), Transcortical 16 (4.7%) suboccipital 1 and combined approach 1; Gross total removal (GTR) was achieved in 247 patients (72.4%), Subtotal removal (STR) in 94 patients (27.6%). Good postoperative outcome at discharge was achieved in 324 (95%) patients while 17 (5%) patients had poor outcome including 5 (1.5%) perioperative deaths. Mean hospital length of stay was 21.87 (8 - 129). There were 42 (12.9%) recurrences with a mean time to recurrence of 28.36 (3 - 84) months, among which 37 (88.1%) underwent surgery for recurrence treatment. Follow-up time ranged from 3 months to 10 years. There was a statistical significance between open transcranial surgery and suprasellar tumors (p Conclusion: Good surgical outcome and long-term tumor control can be achieved through individual-based selective resection, whether total or subtotal resection. Whereas surgical prehistory of CP was found to be a significant risk factor to recurrence (p
