Objective: This study presents a comprehensive analysis of the outcomes associated with the application of the endoscopic endonasal approach in the management of tumors situated within the sellar and suprasellar region.
Methods: Between 2018 and 2024, a total of 87 cases were performed, including 78 cases of simple transsphenoidal approach (TSA), 6 cases of extended TSA, and 3 transclival cases. The mean patient age was 54 years, with a male-to-female ratio of 53:33. Pituitary adenomas were the most common pathology, accounting for 62 cases.
Results: Drawing upon five years of institutional experience, we assessed surgical efficacy, postoperative complications, and long-term patient outcomes. When comparing two periods, 2018–2020 and 2021–2024, a gradual decrease in operative time was observed. Gross total resection (GTR) was achieved in 72% and 74% of cases in the respective periods. No significant differences were observed between the two periods in terms of GTR rates or complication rates, including cerebrospinal fluid (CSF) leakage. Analysis of risk factors for incomplete resection revealed that cavernous sinus invasion was statistically significant (p = 0.007).
Conclusion: Our findings confirm that the endoscopic endonasal approach is an effective and safe technique for managing sellar and suprasellar tumors. The results provide practical guidance on surgical planning, tumor resection, hormonal preservation, and complication management, while highlighting areas for further research and refinement of surgical strategies.
