{Abstract}: Surgery remains the mainstay treatment for parapharyngeal space (PPS) tumors. Given the rapid advance and increasing usage of endoscopic and robotic techniques, we aimed to investigate the surgical trends of PPS tumors in our institution and analyze their impact on patients' treatment outcomes.<BR>All patients who underwent surgical resection of PPS tumors from 2014 to 2021 at the Eye, Ear, Nose, and Throat Hospital of Fudan University were retrospectively reviewed. Student's t-test, Chi-square test, and multinomial logistic regression analyses were used to compare the surgical outcomes between groups.<BR>Of the included 389 patients, the recipients of endoscopic surgery have largely increased in our center, with 17 of 134 cases (12.7%) in the group 2014-2017 and 187 of 255 cases (73.3%) in the group 2018-2021. The use of transoral and trans-nasal approaches increased in recent years (5.2% in 2014-2017 vs. 26.0% in 2018-2021), while that of trans-mandibular and lateral skull base approaches decreased (5.9% in 2014-2017 vs. 0.8% in 2018-2021). Decreased blood loss of operation and decreased risks of postoperative neurovascular complications were observed in the group 2018-2021. Similar findings were observed among patients receiving endoscopic surgery when compared with those receiving conventional surgery.<BR>In our institution, the overall trends in the surgical management of PPS tumors moved towards minimally invasive approaches with the assistance of endoscopy or surgical robots. The two surgical techniques were feasible and safe, and to a great extent, contributed to the improved surgical outcomes we observed in recent years.
