Abstract:Abstract: Objective To investigate the application effects and summarize the clinical experiences of Enhanced Recovery After Surgery (ERAS) for the perioperative management of endoscopic endonasal skull base tumor resection. Methods We retrospectively analyzed patients who had been diagnosed with skull base tumors at the Department of Otorhinolaryngology Head and Neck Surgery, Xuanwu Hospital, Capital Medical University, from January to June 2026. These patients received endoscopic endonasal skull base tumor resection using an ERAS protocol that was applied perioperatively. Patients receiving the same surgery in 2025 were also considered; we compared their baseline characteristics including age, tumor location, pathological type, and reconstruction materials. Two groups were then compared regarding complications, postoperative pain score, postoperative length of stay, and hospitalization cost. Results There were sixty-six patients enrolled in the ERAS group and 147 in the control group. No statistically significant differences existed among the baseline characteristics of both groups. Average postoperative hospital stay of the ERAS group is 8.48±2.47 days while it''s 9.31±2.94 days in the control group, with P<0.05, and the difference is statistically significant. Conclusion Implementation of the ERAS protocol shortened postoperative length of stay. The mean hospital stays and average cost per admission decreased slightly in the ERAS group when compared to the control group, highlighting the importance of ERAS in endoscopic skull base surgery. Larger samples should be studied further so as to elucidate the benefit of this pathway.
