Abstract:
Objective:To evaluate the feasibility, safety and effects of tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach. Methods:This retrospective study included 24 patients who were diagnosed with tumors in the anterior space of the styloid process and treated with the transoral endoscopic medial parapterygomandibular ligament approach. Twenty-four patients who underwent surgery by traditional approach were selected on a 1∶1 ratio as control group. We compared the en bloc resection rate, the operation time, amount of blood loss, the postoperative pain VAS score, recurrence rate, length of hospital stay, complication rate between the two groups. Results:Among the 24 patients, pleomorphic adenoma was confirmed in 18 cases （75.0%）, basal cell adenoma in 2 cases （8.3%）, and neurilemmoma in 4 cases （16.7%）. In the transoral endoscopic group, the en bloc resection rate was 91.7%, the maximum tumor diameter was （42.2±12.2） mm, the operative time was （117.9±29.8）min, the blood loss was （36.7±18.7） mL, the postoperative pain VAS score （1.5±0.7）, no recurrence was observed, length of hospital stay was （10.8±2.9） d. Wound dehiscence occurred in one case in the transoral endoscopic group, and no other postoperative complication was observed. There were significant differences in the operation time, blood loss, the postoperative pain VAS score between the two groups, while no difference was found in gender, age, en bloc resection rate and length of hospital stay. Conclusion:The tumor resection in the anterior space of the styloid process via transoral endoscopic medial parapterygomandibular ligament approach was safe, minimally invasive and feasible.
